+Want to contribute? Great! First, read this page (including the small print at the end).
+
+### Before you contribute
+Before we can use your code, you must sign the
+[Google Individual Contributor License Agreement]
+(https://cla.developers.google.com/about/google-individual)
+(CLA), which you can do online. The CLA is necessary mainly because you own the
+copyright to your changes, even after your contribution becomes part of our
+codebase, so we need your permission to use and distribute your code. We also
+need to be sure of various other things—for instance that you'll tell us if you
+know that your code infringes on other people's patents. You don't have to sign
+the CLA until after you've submitted your code for review and a member has
+approved it, but you must do it before we can put your code into our codebase.
+Before you start working on a larger contribution, you should get in touch with
+us first through the issue tracker with your idea so that we can help out and
+possibly guide you. Coordinating up front makes it much easier to avoid
+frustration later on.
+
+### Code reviews
+All submissions, including submissions by project members, require review. We
+use Github pull requests for this purpose.
+
+### The small print
+Contributions made by corporations are covered by a different agreement than
+the one above, the
+[Software Grant and Corporate Contributor License Agreement]
+(https://cla.developers.google.com/about/google-corporate).

+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+Nest Labs Unit Test
+===================
+
+Nest Labs Unit Test (nlunittest) is designed to provide a
+simple, portable unit test suite framework.
+
+It should be capable of running on just about any system, no
+matter how constrained and depends only on the C Standard Library.
+
+It is recognized and acknowledged that not every piece of code or
+subsystem, library, thread or process can be easily unit tested.
+However, unit tests are a Good Thing&tm; and will give you the
+confidence to make changes and prove to both yourself and other
+colleagues that you have things **right**, in so far as your
+unit tests cover **right**.
+
+Unit tests will be combined with other methods of verification to
+fully cover the various test requirements in the system. The
+purpose of the unit test is to isolate your module's methods and
+ensure that they have the proper output, affect state properly,
+and handle errors appropriately. This ensures each of the building
+blocks of the system functions correctly. These tests can also be
+used for regression testing so that any code changes that affect a
+module's output will be automatically flagged.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+\`configure' configures nlunittest g899ce0d to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  --with-sysroot=DIR Search for dependent libraries within DIR
+                        (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+  DOXYGEN     Doxygen executable
+  DOT         GraphViz 'dot' executable, which may be used, when present, to
+              generate Doxygen class graphs
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+#    Description:
+#      This file describes the settings to be used by the
+#      documentation system # doxygen (www.doxygen.org) for Weave.
+#
+#      This was initially autogenerated 'doxywizard' and then hand-tuned.
+#
+#      All text after a hash (#) is considered a comment and will be
+#      ignored.
+#
+#      The format is:
+#
+#          TAG = value [value, ...]
+#
+#      For lists items can also be appended using:
+#
+#          TAG += value [value, ...]
+#
+#      Values that contain spaces should be placed between quotes (" ")
+#

+#---------------------------------------------------------------------------
+
+# This tag specifies the encoding used for all characters in the config file
+# that follow. The default is UTF-8 which is also the encoding used for all text
+# before the first occurrence of this tag. Doxygen uses libiconv (or the iconv
+# built into libc) for the transcoding. See http://www.gnu.org/software/libiconv
+# for the list of possible encodings.
+# The default value is: UTF-8.
+
+DOXYFILE_ENCODING      = UTF-8
+
+# The PROJECT_NAME tag is a single word (or a sequence of words surrounded by
+# double-quotes, unless you are using Doxywizard) that should identify the
+# project for which the documentation is generated. This name is used in the
+# title of most generated pages and in a few other places.
+# The default value is: My Project.

+# left blank the current directory will be used.
+
+OUTPUT_DIRECTORY       = @abs_builddir@
+
+# If the CREATE_SUBDIRS tag is set to YES, then doxygen will create 4096 sub-
+# directories (in 2 levels) under the output directory of each output format and

+# option can be useful when feeding doxygen a huge amount of source files, where
+# putting all generated files in the same directory would otherwise causes
+# performance problems for the file system.
+# The default value is: NO.

+# documentation generated by doxygen is written. Doxygen will use this
+# information to generate all constant output in the proper language.

+# For example adding
+# "sideeffect=@par Side Effects:\n"
+# will allow you to put the command \sideeffect (or @sideeffect) in the

+# language is one of the parsers supported by doxygen: IDL, Java, Javascript,
+# C#, C, C++, D, PHP, Objective-C, Python, Fortran, VHDL. For instance to make

+(CLA), which you can do online. The CLA is necessary mainly because you own the
+copyright to your changes, even after your contribution becomes part of our

+need to be sure of various other things—for instance that you'll tell us if you
+know that your code infringes on other people's patents. You don't have to sign
+the CLA until after you've submitted your code for review and a member has
+approved it, but you must do it before we can put your code into our codebase.
+Before you start working on a larger contribution, you should get in touch with
+us first through the issue tracker with your idea so that we can help out and
+possibly guide you. Coordinating up front makes it much easier to avoid
+frustration later on.
+
+### Code reviews
+All submissions, including submissions by project members, require review. We

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of

+Nest Labs Build - GNU Autotools
+===============================
+
+Introduction
+------------
+
+The Nest Labs Build - GNU Autotools (nlbuild-autotools) provides a
+customized, turnkey build system framework, based on GNU autotools, for
+standalone Nest Labs software packages that need to support not only
+building on and targeting against standalone build host systems but
+also embedded target systems using GCC-based or -compatible toolchains.
+
+Getting Started
+---------------
+
+This project is typically subtreed into a target project repository
+and serves as the seed for that project's build system.
+
+Assuming that you already have a project repository established in
+git, perform the following in your project repository:
+
+    > 1. % git remote add nlbuild-autotools ssh://<PATH_TO_REPOSITORY>/nlbuild-autotools.git
+    > 2. % git fetch nlbuild-autotools
+
+You can place the nlbuild-autotools package anywhere in your project;
+however, by convention, "third_party/nlbuild-autotools/repo" is recommended:
+
+    > 3. % mkdir third_party
+    > 4. % git subtree add --prefix=third_party/nlbuild-autotools/repo --squash --message="Add subtree mirror of repository 'ssh://<PATH_TO_REPOSITORY>/nlbuild-autotools.git' branch 'master' at commit 'HEAD'." nlbuild-autotools HEAD
+
+At this point, you now have the nlbuild-autotools package integrated
+into your project. The next step is using the
+nlbuild-autotools-provided examples as templates. To do this, a
+convenience script has been provided that will get you started. You
+can tune and customize the results, as needed, for your project. From
+the top level of your project tree:
+

+
+Supported Build Host Systems
+----------------------------
+
+The nlbuild-autotools system supports the following POSIX-based build
+host systems:
+
+  * i686-pc-cygwin
+  * i686-pc-linux-gnu
+  * x86_64-apple-darwin
+  * x86_64-unknown-linux-gnu
+
+Support for these systems includes a set of pre-built, qualified
+versions of GNU autotools along with integration and automation
+scripts to run them.
+
+If support is required for a new POSIX-compatible build host system,
+use the 'build' script in 'tools/packages' to unarchive, build, and
+install the tools for your system.
+
+Please see the FAQ section for more background on why this package
+provides these pre-built tools.
+

+FAQ
+---
+
+Q: Why does nlbuild-autotools have its own built versions of GNU
+   autotools rather than leveraging whatever versions exist on the build
+   host system?
+
+A: Some build host systems such as Mac OS X may not have GNU autotools
+   at all. Other build host systems, such as Linux, may have different
+   distributions or different versions of those distributions in which
+   the versions of GNU autotools are apt to be different.
+
+   This differences lead to different primary and secondary autotools
+   output and, as a consequence, a divergent user and support
+   experience. To avoid this, this package provides a pre-built,
+   qualified set of GNU autotools along with a comprehensive,
+   standalone set of scripts to drive them without reliance on those
+   versions of the tools on the build host system.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse
+##   than renaming).

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.

+# SYNOPSIS
+#
+#   AX_JNI_INCLUDE_DIR
+#
+# DESCRIPTION
+#
+#   AX_JNI_INCLUDE_DIR finds include directories needed for compiling
+#   programs using the JNI interface.
+#
+#   JNI include directories are usually in the Java distribution. This is
+#   deduced from the value of $JAVA_HOME, $JAVAC, or the path to "javac", in
+#   that order. When this macro completes, a list of directories is left in
+#   the variable JNI_INCLUDE_DIRS.
+#
+#   Example usage follows:
+#
+#     AX_JNI_INCLUDE_DIR
+#
+#     for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
+#     do
+#             CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
+#     done
+#
+#   If you want to force a specific compiler:
+#
+#   - at the configure.in level, set JAVAC=yourcompiler before calling
+#   AX_JNI_INCLUDE_DIR
+#
+#   - at the configure level, setenv JAVAC
+#
+#   Note: This macro can work with the autoconf M4 macros for Java programs.
+#   This particular macro is not part of the original set of macros.

+# SYNOPSIS
+#
+#   DX_INIT_DOXYGEN(PROJECT-NAME, DOXYFILE-PATH, [OUTPUT-DIR])
+#   DX_DOXYGEN_FEATURE(ON|OFF)
+#   DX_DOT_FEATURE(ON|OFF)
+#   DX_HTML_FEATURE(ON|OFF)
+#   DX_CHM_FEATURE(ON|OFF)

+#   DX_PDF_FEATURE(ON|OFF)
+#   DX_PS_FEATURE(ON|OFF)
+#
+# DESCRIPTION
+#
+#   The DX_*_FEATURE macros control the default setting for the given
+#   Doxygen feature. Supported features are 'DOXYGEN' itself, 'DOT' for
+#   generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML
+#   help (for MS users), 'CHI' for generating a seperate .chi file by the
+#   .chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate
+#   output formats. The environment variable DOXYGEN_PAPER_SIZE may be
+#   specified to override the default 'a4wide' paper size.
+#
+#   By default, HTML, PDF and PS documentation is generated as this seems to
+#   be the most popular and portable combination. MAN pages created by
+#   Doxygen are usually problematic, though by picking an appropriate subset
+#   and doing some massaging they might be better than nothing. CHM and RTF
+#   are specific for MS (note that you can't generate both HTML and CHM at
+#   the same time). The XML is rather useless unless you apply specialized
+#   post-processing to it.
+#
+#   The macros mainly control the default state of the feature. The use can
+#   override the default by specifying --enable or --disable. The macros
+#   ensure that contradictory flags are not given (e.g.,
+#   --enable-doxygen-html and --enable-doxygen-chm,
+#   --enable-doxygen-anything with --disable-doxygen, etc.) Finally, each
+#   feature will be automatically disabled (with a warning) if the required
+#   programs are missing.
+#
+#   Once all the feature defaults have been specified, call DX_INIT_DOXYGEN
+#   with the following parameters: a one-word name for the project for use
+#   as a filename base etc., an optional configuration file name (the
+#   default is 'Doxyfile', the same as Doxygen's default), and an optional
+#   output directory name (the default is 'doxygen-doc').
+#
+#   Automake Support
+#
+#   The following is a template aminclude.am file for use with Automake.
+#   Make targets and variables values are controlled by the various
+#   DX_COND_* conditionals set by autoconf.
+#
+#   The provided targets are:
+#
+#     doxygen-doc: Generate all doxygen documentation.
+#
+#     doxygen-run: Run doxygen, which will generate some of the
+#                  documentation (HTML, CHM, CHI, MAN, RTF, XML)
+#                  but will not do the post processing required
+#                  for the rest of it (PS, PDF, and some MAN).
+#
+#     doxygen-man: Rename some doxygen generated man pages.
+#
+#     doxygen-ps:  Generate doxygen PostScript documentation.
+#
+#     doxygen-pdf: Generate doxygen PDF documentation.
+#
+#   Note that by default these are not integrated into the automake targets.
+#   If doxygen is used to generate man pages, you can achieve this
+#   integration by setting man3_MANS to the list of man pages generated and
+#   then adding the dependency:
+#
+#     $(man3_MANS): doxygen-doc
+#
+#   This will cause make to run doxygen and generate all the documentation.
+#
+#   The following variable is intended for use in Makefile.am:
+#
+#     DX_CLEANFILES = everything to clean.
+#
+#   Then add this variable to MOSTLYCLEANFILES.

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+
+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+#                             internally or externally to the current
+#                             package or 'external' if the dependent

+#                             the current package. This also serves as

+#                             example, "My Great Software Package".
+#   PACKAGE-VARIABLE-PREFIX : The package-specific prefix applied to variables
+#                             defined as a result of running this macro for the

+#      documentation system # doxygen (www.doxygen.org)
+#
+#      This was initially autogenerated 'doxywizard' and then hand-tuned.
+#
+#      All text after a hash (#) is considered a comment and will be
+#      ignored.
+#
+#      The format is:
+#
+#          TAG = value [value, ...]
+#
+#      For lists items can also be appended using:

+#      Values that contain spaces should be placed between quotes (" ")
+#
+
+#---------------------------------------------------------------------------
+# Project related configuration options
+#---------------------------------------------------------------------------
+
+# This tag specifies the encoding used for all characters in the config file
+# that follow. The default is UTF-8 which is also the encoding used for all text
+# before the first occurrence of this tag. Doxygen uses libiconv (or the iconv
+# built into libc) for the transcoding. See http://www.gnu.org/software/libiconv
+# for the list of possible encodings.
+# The default value is: UTF-8.
+
+DOXYFILE_ENCODING      = UTF-8
+
+# The PROJECT_NAME tag is a single word (or a sequence of words surrounded by
+# double-quotes, unless you are using Doxywizard) that should identify the
+# project for which the documentation is generated. This name is used in the
+# title of most generated pages and in a few other places.
+# The default value is: My Project.

+# could be handy for archiving the generated documentation or if some version
+# control system is used.

+
+# Using the PROJECT_BRIEF tag one can provide an optional one line description
+# for a project that appears at the top of each page and should give viewer a

+# With the PROJECT_LOGO tag one can specify an logo or icon that is included in

+# directories (in 2 levels) under the output directory of each output format and

+# information to generate all constant output in the proper language.
+# Possible values are: Afrikaans, Arabic, Armenian, Brazilian, Catalan, Chinese,
+# Chinese-Traditional, Croatian, Czech, Danish, Dutch, English (United States),

+Run GNU M4 on the FILES, avoiding useless runs.  Output the traces if tracing,
+the frozen file if freezing, otherwise the expansion of the FILES.
+
+If some of the FILES are named \`FILE.m4f\' they are considered to be M4
+frozen files of all the previous files (which are therefore not loaded).
+If \`FILE.m4f\' is not found, then \`FILE.m4\' will be used, together with
+all the previous files.
+
+Some files may be optional, i.e., will only be processed if found in the
+include path, but then must end in \`.m4?\';  the question mark is not part of
+the actual file name.
+
+Operation modes:
+  -h, --help               print this help, then exit
+  -V, --version            print version number, then exit
+  -v, --verbose            verbosely report processing
+  -d, --debug              don\'t remove temporary files
+  -o, --output=FILE        save output in FILE (defaults to \`-\', stdout)
+  -f, --force              don\'t rely on cached values
+  -W, --warnings=CATEGORY  report the warnings falling in CATEGORY
+  -l, --language=LANG      specify the set of M4 macros to use
+  -C, --cache=DIRECTORY    preserve results for future runs in DIRECTORY
+      --no-cache           disable the cache
+  -m, --mode=OCTAL         change the non trace output file mode (0666)
+  -M, --melt               don\'t use M4 frozen files
+
+Languages include:
+  \`Autoconf\'   create Autoconf configure scripts
+  \`Autotest\'   create Autotest test suites
+  \`M4sh\'       create M4sh shell scripts
+  \`M4sugar\'    create M4sugar output
+
+" . Autom4te::ChannelDefs::usage . "
+
+The environment variables \`M4\' and \`WARNINGS\' are honored.
+
+Library directories:
+  -B, --prepend-include=DIR  prepend directory DIR to search path
+  -I, --include=DIR          append directory DIR to search path
+
+Tracing:
+  -t, --trace=MACRO[:FORMAT]  report the MACRO invocations
+  -p, --preselect=MACRO       prepare to trace MACRO in a future run
+
+Freezing:
+  -F, --freeze   produce an M4 frozen state file for FILES
+
+FORMAT defaults to \`\$f:\$l:\$n:\$%\', and can use the following escapes:
+  \$\$     literal \$
+  \$f     file where macro was called
+  \$l     line where macro was called
+  \$d     nesting depth of macro call
+  \$n     name of the macro

+  \$SEP*  all arguments, with newlines, unquoted, and separated by SEP
+  \$SEP%  all arguments, without newlines, unquoted, and separated by SEP
+SEP can be empty for the default (comma for \@ and *, colon for %),

+      # non-distributed .info files, and non-distributed .texi
+      # files.
+      #
+      # * Non-distributed .texi files is important in some packages
+      #   where .texi files are built at make time, probably using
+      #   other binaries built in the package itself, maybe using
+      #   tools or information found on the build host.  Because
+      #   these files are not distributed they are always rebuilt
+      #   at make time; they should therefore not lie in the source
+      #   directory.  One plan was to support this using
+      #   nodist_info_TEXINFOS or something similar.  (Doing this
+      #   requires some sanity checks.  For instance Automake should
+      #   not allow:
+      #      dist_info_TEXINFOS = foo.texi
+      #      nodist_foo_TEXINFOS = included.texi
+      #   because a distributed file should never depend on a
+      #   non-distributed file.)
+      #
+      # * If .texi files are not distributed, then .info files should
+      #   not be distributed either.  There are also cases where one
+      #   wants to distribute .texi files, but does not want to
+      #   distribute the .info files.  For instance the Texinfo package
+      #   distributes the tool used to build these files; it would
+      #   be a waste of space to distribute them.  It's not clear
+      #   which syntax we should use to indicate that .info files should
+      #   not be distributed.  Akim Demaille suggested that eventually
+      #   we switch to a new syntax:
+      #   |  Maybe we should take some inspiration from what's already
+      #   |  done in the rest of Automake.  Maybe there is too much
+      #   |  syntactic sugar here, and you want
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  with a bit of magic to have bar.info represent the whole
+      #   |  bar*info set.  That's a lot more verbose that the current
+      #   |  situation, but it is # not new, hence the user has less
+      #   |  to learn.
+      #	  |
+      #   |  But there is still too much room for meaningless specs:
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     dist_PS = bar.ps something-written-by-hand.ps
+      #   |     nodist_bar_ps_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  here bar.texi is dist_ in line 2, and nodist_ in 4.
+      #
+      # Back to the point, it should be clear that in order to support
+      # non-distributed .info files, we need to build them in the
+      # build tree, not in the source tree (non-distributed .texi
+      # files are less of a problem, because we do not output build
+      # rules for them).  In Automake 1.7 .info build rules have been
+      # largely cleaned up so that .info files get always build in the
+      # build tree, even when distributed.  The idea was that
+      #   (1) if during a VPATH build the .info file was found to be
+      #       absent or out-of-date (in the source tree or in the
+      #       build tree), Make would rebuild it in the build tree.
+      #       If an up-to-date source-tree of the .info file existed,
+      #       make would not rebuild it in the build tree.
+      #   (2) having two copies of .info files, one in the source tree
+      #       and one (newer) in the build tree is not a problem
+      #       because 'make dist' always pick files in the build tree
+      #       first.
+      # However it turned out the be a bad idea for several reasons:
+      #   * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+      #     like GNU Make on point (1) above.  These implementations
+      #     of Make would always rebuild .info files in the build
+      #     tree, even if such files were up to date in the source
+      #     tree.  Consequently, it was impossible to perform a VPATH
+      #     build of a package containing Texinfo files using these
+      #     Make implementations.
+      #     (Refer to the Autoconf Manual, section "Limitation of
+      #     Make", paragraph "VPATH", item "target lookup", for
+      #     an account of the differences between these
+      #     implementations.)
+      #   * The GNU Coding Standards require these files to be built
+      #     in the source-tree (when they are distributed, that is).
+      #   * Keeping a fresher copy of distributed files in the
+      #     build tree can be annoying during development because
+      #     - if the files is kept under CVS, you really want it
+      #       to be updated in the source tree
+      #     - it is confusing that 'make distclean' does not erase
+      #       all files in the build tree.
+      #
+      # Consequently, starting with Automake 1.8, .info files are
+      # built in the source tree again.  Because we still plan to
+      # support non-distributed .info files at some point, we
+      # have a single variable ($INSRC) that controls whether
+      # the current .info file must be built in the source tree
+      # or in the build tree.  Actually this variable is switched
+      # off in two cases:
+      #  (1) For '.info' files that appear to be cleaned; this is for
+      #      backward compatibility with package such as Texinfo,
+      #      which do things like
+      #        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+      #        DISTCLEANFILES = texinfo texinfo-* info*.info*
+      #        # Do not create info files for distribution.
+      #        dist-info:
+      #      in order not to distribute .info files.
+      #  (2) When the undocumented option 'info-in-builddir' is given.
+      #      This is done to allow the developers of GCC, GDB, GNU
+      #      binutils and the GNU bfd library to force the '.info' files
+      #      to be generated in the builddir rather than the srcdir, as
+      #      was once done when the (now removed) 'cygnus' option was
+      #      given.  See automake bug#11034 for more discussion.

+      # non-distributed .info files, and non-distributed .texi
+      # files.
+      #
+      # * Non-distributed .texi files is important in some packages
+      #   where .texi files are built at make time, probably using
+      #   other binaries built in the package itself, maybe using
+      #   tools or information found on the build host.  Because
+      #   these files are not distributed they are always rebuilt
+      #   at make time; they should therefore not lie in the source
+      #   directory.  One plan was to support this using
+      #   nodist_info_TEXINFOS or something similar.  (Doing this
+      #   requires some sanity checks.  For instance Automake should
+      #   not allow:
+      #      dist_info_TEXINFOS = foo.texi
+      #      nodist_foo_TEXINFOS = included.texi
+      #   because a distributed file should never depend on a
+      #   non-distributed file.)
+      #
+      # * If .texi files are not distributed, then .info files should
+      #   not be distributed either.  There are also cases where one
+      #   wants to distribute .texi files, but does not want to
+      #   distribute the .info files.  For instance the Texinfo package
+      #   distributes the tool used to build these files; it would
+      #   be a waste of space to distribute them.  It's not clear
+      #   which syntax we should use to indicate that .info files should
+      #   not be distributed.  Akim Demaille suggested that eventually
+      #   we switch to a new syntax:
+      #   |  Maybe we should take some inspiration from what's already
+      #   |  done in the rest of Automake.  Maybe there is too much
+      #   |  syntactic sugar here, and you want
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  with a bit of magic to have bar.info represent the whole
+      #   |  bar*info set.  That's a lot more verbose that the current
+      #   |  situation, but it is # not new, hence the user has less
+      #   |  to learn.
+      #	  |
+      #   |  But there is still too much room for meaningless specs:
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     dist_PS = bar.ps something-written-by-hand.ps
+      #   |     nodist_bar_ps_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  here bar.texi is dist_ in line 2, and nodist_ in 4.
+      #
+      # Back to the point, it should be clear that in order to support
+      # non-distributed .info files, we need to build them in the
+      # build tree, not in the source tree (non-distributed .texi
+      # files are less of a problem, because we do not output build
+      # rules for them).  In Automake 1.7 .info build rules have been
+      # largely cleaned up so that .info files get always build in the
+      # build tree, even when distributed.  The idea was that
+      #   (1) if during a VPATH build the .info file was found to be
+      #       absent or out-of-date (in the source tree or in the
+      #       build tree), Make would rebuild it in the build tree.
+      #       If an up-to-date source-tree of the .info file existed,
+      #       make would not rebuild it in the build tree.
+      #   (2) having two copies of .info files, one in the source tree
+      #       and one (newer) in the build tree is not a problem
+      #       because 'make dist' always pick files in the build tree
+      #       first.
+      # However it turned out the be a bad idea for several reasons:
+      #   * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+      #     like GNU Make on point (1) above.  These implementations
+      #     of Make would always rebuild .info files in the build
+      #     tree, even if such files were up to date in the source
+      #     tree.  Consequently, it was impossible to perform a VPATH
+      #     build of a package containing Texinfo files using these
+      #     Make implementations.
+      #     (Refer to the Autoconf Manual, section "Limitation of
+      #     Make", paragraph "VPATH", item "target lookup", for
+      #     an account of the differences between these
+      #     implementations.)
+      #   * The GNU Coding Standards require these files to be built
+      #     in the source-tree (when they are distributed, that is).
+      #   * Keeping a fresher copy of distributed files in the
+      #     build tree can be annoying during development because
+      #     - if the files is kept under CVS, you really want it
+      #       to be updated in the source tree
+      #     - it is confusing that 'make distclean' does not erase
+      #       all files in the build tree.
+      #
+      # Consequently, starting with Automake 1.8, .info files are
+      # built in the source tree again.  Because we still plan to
+      # support non-distributed .info files at some point, we
+      # have a single variable ($INSRC) that controls whether
+      # the current .info file must be built in the source tree
+      # or in the build tree.  Actually this variable is switched
+      # off in two cases:
+      #  (1) For '.info' files that appear to be cleaned; this is for
+      #      backward compatibility with package such as Texinfo,
+      #      which do things like
+      #        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+      #        DISTCLEANFILES = texinfo texinfo-* info*.info*
+      #        # Do not create info files for distribution.
+      #        dist-info:
+      #      in order not to distribute .info files.
+      #  (2) When the undocumented option 'info-in-builddir' is given.
+      #      This is done to allow the developers of GCC, GDB, GNU
+      #      binutils and the GNU bfd library to force the '.info' files
+      #      to be generated in the builddir rather than the srcdir, as
+      #      was once done when the (now removed) 'cygnus' option was
+      #      given.  See automake bug#11034 for more discussion.

+Run `autoconf' (and `autoheader', `aclocal', `automake', `autopoint'
+(formerly `gettextize'), and `libtoolize' where appropriate)
+repeatedly to remake the GNU Build System files in specified
+DIRECTORIES and their subdirectories (defaulting to `.').
+
+By default, it only remakes those files that are older than their
+sources.  If you install new versions of the GNU Build System,
+you can make `autoreconf' remake all of the files by giving it the
+`--force' option.
+
+Operation modes:
+  -h, --help               print this help, then exit
+  -V, --version            print version number, then exit
+  -v, --verbose            verbosely report processing
+  -d, --debug              don't remove temporary files
+  -f, --force              consider all files obsolete
+  -i, --install            copy missing auxiliary files
+      --no-recursive       don't rebuild sub-packages

+#		  ## How `autoupdate' functions.  ##
+#		  ## ---------------------------- ##
+#
+# The task of `autoupdate' is not trivial: the biggest difficulty being
+# that you must limit the changes to the parts that really need to be
+# updated.  Finding a satisfying implementation proved to be quite hard,
+# as this is the fifth implementation of `autoupdate'.
+#
+# Below, we will use a simple example of an obsolete macro:
+#
+#     AU_DEFUN([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))])
+#     AC_DEFUN([NEW], [echo "sum($1) = $2"])
+#
+# the input file contains
+#
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Of course the expected output is
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2], [3])
+#     NEW([0, 0], [0])
+#
+#
+# # First implementation: sed
+# # =========================
+#
+# The first implementation was only able to change the name of obsolete
+# macros.
+#
+# The file `acoldnames.m4' defined the old names based on the new names.
+# It was simple then to produce a sed script such as:
+#
+#     s/OLD/NEW/g
+#
+# Updating merely consisted in running this script on the file to
+# update.
+#
+# This scheme suffers from an obvious limitation: that `autoupdate' was
+# unable to cope with new macros that just swap some of its arguments
+# compared to the old macro.  Fortunately, that was enough to upgrade
+# from Autoconf 1 to Autoconf 2.  (But I have no idea whether the
+# changes in Autoconf 2 were precisely limited by this constraint.)
+#
+#
+# # Second implementation: hooks
+# # ============================
+#
+# The version 2.15 of Autoconf brought a vast number of changes compared
+# to 2.13, so a solution was needed.  One could think of extending the
+# `sed' scripts with specialized code for complex macros.  However, this
+# approach is of course full of flaws:
+#
+# a. the Autoconf maintainers have to write these snippets, which we
+#    just don't want to,
+#
+# b. I really don't think you'll ever manage to handle the quoting of
+#    m4 with a sed script.
+#
+# To satisfy a., let's remark that the code which implements the old
+# features in term of the new feature is exactly the code which should
+# replace the old code.
+#
+# To answer point b, as usual in the history of Autoconf, the answer, at
+# least on the paper, is simple: m4 is the best tool to parse m4, so
+# let's use m4.
+#
+# Therefore the specification is:
+#
+#     I want to be able to tell Autoconf, well, m4, that the macro I
+#     am currently defining is an obsolete macro (so that the user is
+#     warned), and its code is the code to use when running autoconf,
+#     but that the very same code has to be used when running
+#     autoupdate.  To summarize, the interface I want is
+#     `AU_DEFUN(OLD-NAME, NEW-CODE)'.
+#
+#
+# Now for the technical details.
+#
+# When running autoconf, except for the warning, AU_DEFUN is basically
+# AC_DEFUN.
+#
+# When running autoupdate, we want *only* OLD-NAMEs to be expanded.
+# This obviously means that acgeneral.m4 and acspecific.m4 must not be
+# loaded.  Nonetheless, because we want to use a rich set of m4
+# features, m4sugar.m4 is needed.  Please note that the fact that
+# Autoconf's macros are not loaded is positive on two points:
+#
+# - we do get an updated `configure.ac', not a `configure'!
+#
+# - the old macros are replaced by *calls* to the new-macros, not the
+#   body of the new macros, since their body is not defined!!!
+#   (Whoa, that's really beautiful!).
+#
+# Additionally we need to disable the quotes when reading the input for
+# two reasons: first because otherwise `m4' will swallow the quotes of
+# other macros:
+#
+#     NEW([1, 2], 3)
+#     => NEW(1, 2, 3)
+#
+# and second, because we want to update the macro calls which are
+# quoted, i.e., we want
+#
+#     FOO([OLD(1, 2)])
+#     => FOO([NEW([1, 2], [3])])
+#
+# If we don't disable the quotes, only the macros called at the top
+# level would be updated.
+#
+# So, let's disable the quotes.
+#
+# Well, not quite: m4sugar.m4 still needs to use quotes for some macros.
+# Well, in this case, when running in autoupdate code, each macro first
+# reestablishes the quotes, expands itself, and disables the quotes.
+#
+# Thinking a bit more, you realize that in fact, people may use `define',
+# `ifelse' etc. in their files, and you certainly don't want to process
+# them.  Another example is `dnl': you don't want to remove the
+# comments.  You then realize you don't want exactly to import m4sugar:
+# you want to specify when it is enabled (macros active), and disabled.
+# m4sugar provides m4_disable/m4_enable to this end.
+#
+# You're getting close to it.  Now remains one task: how to handle
+# twofold definitions?
+#
+# Remember that the same AU_DEFUN must be understood in two different
+# ways, the AC way, and the AU way.
+#
+# One first solution is to check whether acgeneral.m4 was loaded.  But
+# that's definitely not cute.  Another is simply to install `hooks',
+# that is to say, to keep in some place m4 knows, late `define' to be
+# triggered *only* in AU mode.
+#
+# You first think of designing AU_DEFUN like this:
+#
+# 1. AC_DEFUN(OLD-NAME,
+#	      [Warn the user OLD-NAME is obsolete.
+#	       NEW-CODE])
+#
+# 2. Store for late AU binding([define(OLD_NAME,
+#				[Reestablish the quotes.
+#				 NEW-CODE
+#				 Disable the quotes.])])
+#
+# but this will not work: NEW-CODE probably uses $1, $2 etc. and these
+# guys will be replaced with the argument of `Store for late AU binding'
+# when you call it.
+#
+# I don't think there is a means to avoid this using this technology
+# (remember that $1 etc. are *always* expanded in m4).  You may also try
+# to replace them with $[1] to preserve them for a later evaluation, but
+# if `Store for late AU binding' is properly written, it will remain
+# quoted till the end...
+#
+# You have to change technology.  Since the problem is that `$1'
+# etc. should be `consumed' right away, one solution is to define now a
+# second macro, `AU_OLD-NAME', and to install a hook than binds OLD-NAME
+# to AU_OLD-NAME.  Then, autoupdate.m4 just need to run the hooks.  By
+# the way, the same method was used in autoheader.
+#
+#
+# # Third implementation: m4 namespaces by m4sugar
+# # ==============================================
+#
+# Actually, this implementation was just a clean up of the previous
+# implementation: instead of defining hooks by hand, m4sugar was equipped
+# with `namespaces'.  What are they?
+#
+# Sometimes we want to disable some *set* of macros, and restore them
+# later.  We provide support for this via namespaces.
+#
+# There are basically three characters playing this scene: defining a
+# macro in a namespace, disabling a namespace, and restoring a namespace
+# (i.e., all the definitions it holds).
+#
+# Technically, to define a MACRO in NAMESPACE means to define the macro
+# named `NAMESPACE::MACRO' to the VALUE.  At the same time, we append
+# `undefine(NAME)' in the macro named `m4_disable(NAMESPACE)', and
+# similarly a binding of NAME to the value of `NAMESPACE::MACRO' in
+# `m4_enable(NAMESPACE)'.  These mechanisms allow to bind the macro of
+# NAMESPACE and to unbind them at will.
+#
+# Of course this implementation is really inefficient: m4 has to grow
+# strings which can become quickly huge, which slows it significantly.
+#
+# In particular one should avoid as much as possible to use `define' for
+# temporaries.  Now that `define' has quite a complex meaning, it is an
+# expensive operations that should be limited to macros.  Use
+# `m4_define' for temporaries.
+#
+# Private copies of the macros we used in entering / exiting the m4sugar
+# namespace.  It is much more convenient than fighting with the renamed
+# version of define etc.
+#
+#
+#
+# Those two implementations suffered from serious problems:
+#
+# - namespaces were really expensive, and incurred a major performance
+#   loss on `autoconf' itself, not only `autoupdate'.  One solution
+#   would have been the limit the use of namespaces to `autoupdate', but
+#   that's again some complications on m4sugar, which really doesn't need
+#   this.  So we wanted to get rid of the namespaces.
+#
+# - since the quotes were disabled, autoupdate was sometimes making
+#   wrong guesses, for instance on:
+#
+#     foo([1, 2])
+#
+#   m4 saw 2 arguments: `[1'and `2]'.  A simple solution, somewhat
+#   fragile, is to reestablish the quotes right before all the obsolete
+#   macros, i.e., to use sed so that the previous text becomes
+#
+#     changequote([, ])foo([1, 2])
+#
+#   To this end, one wants to trace the definition of obsolete macros.
+#
+# It was there that the limitations of the namespace approach became
+# painful: because it was a complex machinery playing a lot with the
+# builtins of m4 (hence, quite fragile), tracing was almost impossible.
+#
+#
+# So this approach was dropped.
+#
+#
+# # The fourth implementation: two steps
+# # ====================================
+#
+# If you drop the uses of namespaces, you no longer can compute the
+# updated value, and replace the old call with it simultaneously.
+#
+# Obviously you will use m4 to compute the updated values, but you may
+# use some other tool to achieve the replacement.  Personally, I trust
+# nobody but m4 to parse m4, so below, m4 will perform the two tasks.
+#
+# How can m4 be used to replace *some* macros calls with newer values.
+# Well, that's dead simple: m4 should learn the definitions of obsolete
+# macros, forget its builtins, disable the quotes, and then run on the
+# input file, which amounts to doing this:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# which will result in
+#
+#     dnl The Unbelievable Truth
+#     NEW(1, 2, m4_eval(1 + 2))
+#     NEW([0, 0],
+#	  0)
+#
+# Grpmh.  Two problems.  A minor problem: it would have been much better
+# to have the `m4_eval' computed, and a major problem: you lost the
+# quotation in the result.
+#
+# Let's address the big problem first.  One solution is to define any
+# modern macro to rewrite its calls with the proper quotation, thanks to
+# `$@'.  Again, tracing the `define's makes it possible to know which
+# are these macros, so you input is:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
+#     define([NEW], [[NEW($@)]changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     changequote([, ])NEW([0, 0],
+#	  0)
+#
+# which results in
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2],[m4_eval(1 + 2)])
+#     NEW([0, 0],[0])
+#
+# Our problem is solved, i.e., the first call to `NEW' is properly
+# quoted, but introduced another problem: we changed the layout of the
+# second calls, which can be a drama in the case of huge macro calls
+# (think of `AC_TRY_RUN' for instance).  This example didn't show it,
+# but we also introduced parens to macros which did not have some:
+#
+#     AC_INIT
+#     => AC_INIT()
+#
+# No big deal for the semantics (unless the macro depends upon $#, which
+# is bad), but the users would not be happy.
+#
+# Additionally, we introduced quotes that were not there before, which is
+# OK in most cases, but could change the semantics of the file.
+#
+# Cruel dilemma: we do want the auto-quoting definition of `NEW' when
+# evaluating `OLD', but we don't when we evaluate the second `NEW'.
+# Back to namespaces?
+#
+# No.
+#
+#
+# # Second step: replacement
+# # ------------------------
+#
+# No, as announced above, we will work in two steps: in a first step we
+# compute the updated values, and in a second step we replace them.  Our
+# goal is something like this:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([1, 2], [3])changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# i.e., the new value of `OLD' is precomputed using the auto-quoting
+# definition of `NEW' and the m4 builtins.  We'll see how afterwards,
+# let's finish with the replacement.
+#
+# Of course the solution above is wrong: if there were other calls to
+# `OLD' with different values, we would smash them to the same value.
+# But it is quite easy to generalize the scheme above:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD([1],[2])], [NEW([1, 2], [3])])
+#     define([OLD], [defn([OLD($@)])changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# i.e., for each call to obsolete macros, we build an array `call =>
+# value', and use a macro to dispatch these values.  This results in:
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2], [3])
+#     NEW([0, 0],
+#	  0)
+#
+# In French, we say `Youpi !', which you might roughly translate as
+# `Yippee!'.
+#
+#
+# # First step: computation
+# # -----------------------
+#
+# Let's study the anatomy of the file, and name its sections:
+#
+# prologue
+#     divert(-1)dnl
+#     changequote([, ])
+# values
+#     define([OLD([1],[2])], [NEW([1, 2], [3])])
+# dispatcher
+#     define([OLD], [defn([OLD($@)])changequote()])
+# disabler
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+# input
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+#
+# # Computing the `values' section
+# # ..............................
+#
+# First we need to get the list of all the AU macro uses.  To this end,
+# first get the list of all the AU macros names by tracing `AU_DEFUN' in
+# the initialization of autoconf.  This list is computed in the file
+# `au.txt' below.
+#
+# Then use this list to trace all the AU macro uses in the input.  The
+# goal is obtain in the case of our example:
+#
+#     [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
+#
+# This is the file `values.in' below.
+#
+# We want to evaluate this with only the builtins (in fact m4sugar), the
+# auto-quoting definitions of the new macros (`new.m4'), and the
+# definition of the old macros (`old.m4').  Computing these last two
+# files is easy: it's just a matter of using the right `--trace' option.
+#
+# So the content of `values.in' is:
+#
+#     include($autoconf_dir/m4sugar.m4)
+#     m4_include(new.m4)
+#     m4_include(old.m4)
+#     divert(0)dnl
+#     [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
+#
+# We run m4 on it, which yields:
+#
+#     define([OLD([1],[2])],@<<@NEW([1, 2], [3])@>>@)
+#
+# Transform `@<<@' and `@>>@' into quotes and we get
+#
+#     define([OLD([1],[2])],[NEW([1, 2], [3])])
+#
+# This is `values.m4'.
+#
+#
+# # Computing the `dispatcher' section
+# # ..................................
+#
+# The `prologue', and the `disabler' are simple and need no commenting.
+#
+# To compute the `dispatcher' (`dispatch.m4'), again, it is a simple
+# matter of using the right `--trace'.
+#
+# Finally, the input is not exactly the input file, rather it is the
+# input file with the added `changequote'.  To this end, we build
+# `quote.sed'.
+#
+#
+# # Putting it all together
+# # .......................
+#
+# We build the file `input.m4' which contains:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     include(values.m4)
+#     include(dispatch.m4)
+#     undefine([dnl])
+#     undefine([eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# And we just run m4 on it.  Et voila`, Monsieur !  Mais oui, mais oui.
+#
+# Well, there are a few additional technicalities.  For instance, we
+# rely on `changequote', `ifelse' and `defn', but we don't want to
+# interpret the changequotes of the user, so we simply use another name:
+# `_au_changequote' etc.
+#
+#
+# # Failure of the fourth approach
+# # ------------------------------
+#
+# This approach is heavily based on traces, but then there is an obvious
+# problem: non expanded code will never be seen.  In particular, the body
+# of a `define' definition is not seen, so on the input
+#
+#	  define([idem], [OLD(0, [$1])])
+#
+# autoupdate would never see the `OLD', and wouldn't have updated it.
+# Worse yet, if `idem(0)' was used later, then autoupdate sees that
+# `OLD' is used, computes the result for `OLD(0, 0)' and sets up a
+# dispatcher for `OLD'.  Since there was no computed value for `OLD(0,
+# [$1])', the dispatcher would have replaced with... nothing, leading
+# to
+#
+#	  define([idem], [])
+#
+# With some more thinking, you see that the two step approach is wrong,
+# the namespace approach was much saner.
+#
+# But you learned a lot, in particular you realized that using traces
+# can make it possible to simulate namespaces!
+#
+#
+#
+# # The fifth implementation: m4 namespaces by files
+# # ================================================
+#
+# The fourth implementation demonstrated something unsurprising: you
+# cannot precompute, i.e., the namespace approach was the right one.
+# Still, we no longer want them, they're too expensive.  Let's have a
+# look at the way it worked.
+#
+# When updating
+#
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# you evaluate `input.m4':
+#
+#     divert(-1)
+#     changequote([, ])
+#     define([OLD],
+#     [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
+#     ...
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# where `m4_disable' undefines the m4 and m4sugar, and disables the quotes
+# and comments:
+#
+#     define([m4_disable],
+#     [undefine([__file__])
+#     ...
+#     changecom(#)
+#     changequote()])
+#
+# `m4_enable' does the converse: reestablish quotes and comments
+# --easy--, reestablish m4sugar --easy: just load `m4sugar.m4' again-- and
+# reenable the builtins.  This later task requires that you first save
+# the builtins.  And BTW, the definition above of `m4_disable' cannot
+# work: you undefined `changequote' before using it!  So you need to use
+# your privates copies of the builtins.  Let's introduce three files for
+# this:
+#
+#  `m4save.m4'
+#    moves the m4 builtins into the `_au_' pseudo namespace,
+#  `unm4.m4'
+#    undefines the builtins,
+#  `m4.m4'
+#    restores them.
+#
+# So `input.m4' is:
+#
+#     divert(-1)
+#     changequote([, ])
+#
+#     include([m4save.m4])
+#
+#     # Import AU.
+#     define([OLD],
+#     [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
+#
+#     define([_au_enable],
+#     [_au_changecom([#])
+#     _au_include([m4.m4])
+#     _au_include(m4sugar.m4)])
+#
+#     define([_au_disable],
+#     [# Disable m4sugar.
+#     # Disable the m4 builtins.
+#     _au_include([unm4.m4])
+#     # 1. Disable special characters.
+#     _au_changequote()
+#     _au_changecom()])
+#
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Based on what we learned in the fourth implementation we know that we
+# have to enable the quotes *before* any AU macro, and we know we need
+# to build autoquoting versions of the AC macros.  But the autoquoting
+# AC definitions must be disabled in the rest of the file, and enabled
+# inside AU macros.
+#
+# Using `autoconf --trace' it is easy to build the files
+#
+#   `ac.m4'
+#     define the autoquoting AC fake macros
+#   `disable.m4'
+#     undefine the m4sugar and AC autoquoting macros.
+#   `au.m4'
+#     definitions of the AU macros (such as `OLD' above).
+#
+# Now, `input.m4' is:
+#
+#     divert(-1)
+#     changequote([, ])
+#
+#     include([m4save.m4])
+#     # Import AU.
+#     include([au.m4])
+#
+#     define([_au_enable],
+#     [_au_changecom([#])
+#     _au_include([m4.m4])
+#     _au_include(m4sugar.m4)
+#     _au_include(ac.m4)])
+#
+#     define([_au_disable],
+#     [_au_include([disable.m4])
+#     _au_include([unm4.m4])
+#     # 1. Disable special characters.
+#     _au_changequote()
+#     _au_changecom()])
+#
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     _au_changequote([, ])OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Finally, version V is ready.
+#
+# Well... almost.
+#
+# There is a slight problem that remains: if an AU macro OUTER includes
+# an AU macro INNER, then _au_enable will be run when entering OUTER
+# and when entering INNER (not good, but not too bad yet).  But when
+# getting out of INNER, _au_disable will disable everything while we
+# were still in OUTER.  Badaboom.
+#
+# Therefore _au_enable and _au_disable have to be written to work by
+# pairs: each _au_enable pushdef's _au_enabled, and each _au_disable
+# popdef's _au_enabled.  And of course _au_enable and _au_disable are
+# effective when _au_enabled is *not* defined.
+#
+# Finally, version V' is ready.  And there is much rejoicing.  (And I
+# have free time again.  I think.  Yeah, right.)

+Run GNU M4 on the FILES, avoiding useless runs.  Output the traces if tracing,
+the frozen file if freezing, otherwise the expansion of the FILES.
+
+If some of the FILES are named \`FILE.m4f\' they are considered to be M4
+frozen files of all the previous files (which are therefore not loaded).
+If \`FILE.m4f\' is not found, then \`FILE.m4\' will be used, together with
+all the previous files.
+
+Some files may be optional, i.e., will only be processed if found in the
+include path, but then must end in \`.m4?\';  the question mark is not part of
+the actual file name.
+
+Operation modes:
+  -h, --help               print this help, then exit
+  -V, --version            print version number, then exit
+  -v, --verbose            verbosely report processing
+  -d, --debug              don\'t remove temporary files
+  -o, --output=FILE        save output in FILE (defaults to \`-\', stdout)

+  -W, --warnings=CATEGORY  report the warnings falling in CATEGORY
+  -l, --language=LANG      specify the set of M4 macros to use
+  -C, --cache=DIRECTORY    preserve results for future runs in DIRECTORY
+      --no-cache           disable the cache
+  -m, --mode=OCTAL         change the non trace output file mode (0666)
+  -M, --melt               don\'t use M4 frozen files
+
+Languages include:
+  \`Autoconf\'   create Autoconf configure scripts
+  \`Autotest\'   create Autotest test suites
+  \`M4sh\'       create M4sh shell scripts
+  \`M4sugar\'    create M4sugar output
+
+" . Autom4te::ChannelDefs::usage . "
+
+The environment variables \`M4\' and \`WARNINGS\' are honored.

+Library directories:

+
+Tracing:
+  -t, --trace=MACRO[:FORMAT]  report the MACRO invocations
+  -p, --preselect=MACRO       prepare to trace MACRO in a future run
+
+Freezing:
+  -F, --freeze   produce an M4 frozen state file for FILES
+
+FORMAT defaults to \`\$f:\$l:\$n:\$%\', and can use the following escapes:
+  \$\$     literal \$
+  \$f     file where macro was called
+  \$l     line where macro was called
+  \$d     nesting depth of macro call
+  \$n     name of the macro

+  \$SEP*  all arguments, with newlines, unquoted, and separated by SEP
+  \$SEP%  all arguments, without newlines, unquoted, and separated by SEP
+SEP can be empty for the default (comma for \@ and *, colon for %),

+      # non-distributed .info files, and non-distributed .texi
+      # files.
+      #
+      # * Non-distributed .texi files is important in some packages
+      #   where .texi files are built at make time, probably using
+      #   other binaries built in the package itself, maybe using
+      #   tools or information found on the build host.  Because
+      #   these files are not distributed they are always rebuilt
+      #   at make time; they should therefore not lie in the source
+      #   directory.  One plan was to support this using
+      #   nodist_info_TEXINFOS or something similar.  (Doing this
+      #   requires some sanity checks.  For instance Automake should
+      #   not allow:
+      #      dist_info_TEXINFOS = foo.texi
+      #      nodist_foo_TEXINFOS = included.texi
+      #   because a distributed file should never depend on a
+      #   non-distributed file.)
+      #
+      # * If .texi files are not distributed, then .info files should
+      #   not be distributed either.  There are also cases where one
+      #   wants to distribute .texi files, but does not want to
+      #   distribute the .info files.  For instance the Texinfo package
+      #   distributes the tool used to build these files; it would
+      #   be a waste of space to distribute them.  It's not clear
+      #   which syntax we should use to indicate that .info files should
+      #   not be distributed.  Akim Demaille suggested that eventually
+      #   we switch to a new syntax:
+      #   |  Maybe we should take some inspiration from what's already
+      #   |  done in the rest of Automake.  Maybe there is too much
+      #   |  syntactic sugar here, and you want
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  with a bit of magic to have bar.info represent the whole
+      #   |  bar*info set.  That's a lot more verbose that the current
+      #   |  situation, but it is # not new, hence the user has less
+      #   |  to learn.
+      #	  |
+      #   |  But there is still too much room for meaningless specs:
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     dist_PS = bar.ps something-written-by-hand.ps
+      #   |     nodist_bar_ps_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  here bar.texi is dist_ in line 2, and nodist_ in 4.
+      #
+      # Back to the point, it should be clear that in order to support
+      # non-distributed .info files, we need to build them in the
+      # build tree, not in the source tree (non-distributed .texi
+      # files are less of a problem, because we do not output build
+      # rules for them).  In Automake 1.7 .info build rules have been
+      # largely cleaned up so that .info files get always build in the
+      # build tree, even when distributed.  The idea was that
+      #   (1) if during a VPATH build the .info file was found to be
+      #       absent or out-of-date (in the source tree or in the
+      #       build tree), Make would rebuild it in the build tree.
+      #       If an up-to-date source-tree of the .info file existed,
+      #       make would not rebuild it in the build tree.
+      #   (2) having two copies of .info files, one in the source tree
+      #       and one (newer) in the build tree is not a problem
+      #       because 'make dist' always pick files in the build tree
+      #       first.
+      # However it turned out the be a bad idea for several reasons:
+      #   * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+      #     like GNU Make on point (1) above.  These implementations
+      #     of Make would always rebuild .info files in the build
+      #     tree, even if such files were up to date in the source
+      #     tree.  Consequently, it was impossible to perform a VPATH
+      #     build of a package containing Texinfo files using these
+      #     Make implementations.
+      #     (Refer to the Autoconf Manual, section "Limitation of
+      #     Make", paragraph "VPATH", item "target lookup", for
+      #     an account of the differences between these
+      #     implementations.)
+      #   * The GNU Coding Standards require these files to be built
+      #     in the source-tree (when they are distributed, that is).
+      #   * Keeping a fresher copy of distributed files in the
+      #     build tree can be annoying during development because
+      #     - if the files is kept under CVS, you really want it
+      #       to be updated in the source tree
+      #     - it is confusing that 'make distclean' does not erase
+      #       all files in the build tree.
+      #
+      # Consequently, starting with Automake 1.8, .info files are
+      # built in the source tree again.  Because we still plan to
+      # support non-distributed .info files at some point, we
+      # have a single variable ($INSRC) that controls whether
+      # the current .info file must be built in the source tree
+      # or in the build tree.  Actually this variable is switched
+      # off in two cases:
+      #  (1) For '.info' files that appear to be cleaned; this is for
+      #      backward compatibility with package such as Texinfo,
+      #      which do things like
+      #        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+      #        DISTCLEANFILES = texinfo texinfo-* info*.info*
+      #        # Do not create info files for distribution.
+      #        dist-info:
+      #      in order not to distribute .info files.
+      #  (2) When the undocumented option 'info-in-builddir' is given.
+      #      This is done to allow the developers of GCC, GDB, GNU
+      #      binutils and the GNU bfd library to force the '.info' files
+      #      to be generated in the builddir rather than the srcdir, as
+      #      was once done when the (now removed) 'cygnus' option was

+      # non-distributed .info files, and non-distributed .texi
+      # files.
+      #
+      # * Non-distributed .texi files is important in some packages
+      #   where .texi files are built at make time, probably using
+      #   other binaries built in the package itself, maybe using
+      #   tools or information found on the build host.  Because
+      #   these files are not distributed they are always rebuilt
+      #   at make time; they should therefore not lie in the source
+      #   directory.  One plan was to support this using
+      #   nodist_info_TEXINFOS or something similar.  (Doing this
+      #   requires some sanity checks.  For instance Automake should
+      #   not allow:
+      #      dist_info_TEXINFOS = foo.texi
+      #      nodist_foo_TEXINFOS = included.texi
+      #   because a distributed file should never depend on a
+      #   non-distributed file.)
+      #
+      # * If .texi files are not distributed, then .info files should
+      #   not be distributed either.  There are also cases where one
+      #   wants to distribute .texi files, but does not want to
+      #   distribute the .info files.  For instance the Texinfo package
+      #   distributes the tool used to build these files; it would
+      #   be a waste of space to distribute them.  It's not clear
+      #   which syntax we should use to indicate that .info files should
+      #   not be distributed.  Akim Demaille suggested that eventually
+      #   we switch to a new syntax:
+      #   |  Maybe we should take some inspiration from what's already
+      #   |  done in the rest of Automake.  Maybe there is too much
+      #   |  syntactic sugar here, and you want
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  with a bit of magic to have bar.info represent the whole
+      #   |  bar*info set.  That's a lot more verbose that the current
+      #   |  situation, but it is # not new, hence the user has less
+      #   |  to learn.
+      #	  |
+      #   |  But there is still too much room for meaningless specs:
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     dist_PS = bar.ps something-written-by-hand.ps
+      #   |     nodist_bar_ps_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  here bar.texi is dist_ in line 2, and nodist_ in 4.
+      #
+      # Back to the point, it should be clear that in order to support
+      # non-distributed .info files, we need to build them in the
+      # build tree, not in the source tree (non-distributed .texi
+      # files are less of a problem, because we do not output build
+      # rules for them).  In Automake 1.7 .info build rules have been
+      # largely cleaned up so that .info files get always build in the
+      # build tree, even when distributed.  The idea was that
+      #   (1) if during a VPATH build the .info file was found to be
+      #       absent or out-of-date (in the source tree or in the
+      #       build tree), Make would rebuild it in the build tree.
+      #       If an up-to-date source-tree of the .info file existed,
+      #       make would not rebuild it in the build tree.
+      #   (2) having two copies of .info files, one in the source tree
+      #       and one (newer) in the build tree is not a problem
+      #       because 'make dist' always pick files in the build tree
+      #       first.
+      # However it turned out the be a bad idea for several reasons:
+      #   * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+      #     like GNU Make on point (1) above.  These implementations
+      #     of Make would always rebuild .info files in the build
+      #     tree, even if such files were up to date in the source
+      #     tree.  Consequently, it was impossible to perform a VPATH
+      #     build of a package containing Texinfo files using these
+      #     Make implementations.
+      #     (Refer to the Autoconf Manual, section "Limitation of
+      #     Make", paragraph "VPATH", item "target lookup", for
+      #     an account of the differences between these
+      #     implementations.)
+      #   * The GNU Coding Standards require these files to be built
+      #     in the source-tree (when they are distributed, that is).
+      #   * Keeping a fresher copy of distributed files in the
+      #     build tree can be annoying during development because
+      #     - if the files is kept under CVS, you really want it
+      #       to be updated in the source tree
+      #     - it is confusing that 'make distclean' does not erase
+      #       all files in the build tree.
+      #
+      # Consequently, starting with Automake 1.8, .info files are
+      # built in the source tree again.  Because we still plan to
+      # support non-distributed .info files at some point, we
+      # have a single variable ($INSRC) that controls whether
+      # the current .info file must be built in the source tree
+      # or in the build tree.  Actually this variable is switched
+      # off in two cases:
+      #  (1) For '.info' files that appear to be cleaned; this is for
+      #      backward compatibility with package such as Texinfo,
+      #      which do things like
+      #        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+      #        DISTCLEANFILES = texinfo texinfo-* info*.info*
+      #        # Do not create info files for distribution.
+      #        dist-info:
+      #      in order not to distribute .info files.
+      #  (2) When the undocumented option 'info-in-builddir' is given.
+      #      This is done to allow the developers of GCC, GDB, GNU
+      #      binutils and the GNU bfd library to force the '.info' files
+      #      to be generated in the builddir rather than the srcdir, as

+Run `autoconf' (and `autoheader', `aclocal', `automake', `autopoint'
+(formerly `gettextize'), and `libtoolize' where appropriate)
+repeatedly to remake the GNU Build System files in specified
+DIRECTORIES and their subdirectories (defaulting to `.').
+
+By default, it only remakes those files that are older than their
+sources.  If you install new versions of the GNU Build System,
+you can make `autoreconf' remake all of the files by giving it the
+`--force' option.
+
+Operation modes:
+  -h, --help               print this help, then exit
+  -V, --version            print version number, then exit
+  -v, --verbose            verbosely report processing
+  -d, --debug              don't remove temporary files
+  -f, --force              consider all files obsolete
+  -i, --install            copy missing auxiliary files
+      --no-recursive       don't rebuild sub-packages
+  -s, --symlink            with -i, install symbolic links instead of copies

+The environment variable \`WARNINGS\' is honored.  Some subtools might
+support other warning types, using \`all' is encouraged.
+
+Library directories:
+  -B, --prepend-include=DIR  prepend directory DIR to search path
+  -I, --include=DIR          append directory DIR to search path

+#		  ## How `autoupdate' functions.  ##
+#		  ## ---------------------------- ##
+#
+# The task of `autoupdate' is not trivial: the biggest difficulty being
+# that you must limit the changes to the parts that really need to be
+# updated.  Finding a satisfying implementation proved to be quite hard,
+# as this is the fifth implementation of `autoupdate'.
+#
+# Below, we will use a simple example of an obsolete macro:
+#
+#     AU_DEFUN([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))])
+#     AC_DEFUN([NEW], [echo "sum($1) = $2"])
+#
+# the input file contains
+#
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Of course the expected output is
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2], [3])
+#     NEW([0, 0], [0])
+#
+#
+# # First implementation: sed
+# # =========================
+#
+# The first implementation was only able to change the name of obsolete
+# macros.
+#
+# The file `acoldnames.m4' defined the old names based on the new names.
+# It was simple then to produce a sed script such as:
+#
+#     s/OLD/NEW/g
+#
+# Updating merely consisted in running this script on the file to
+# update.
+#
+# This scheme suffers from an obvious limitation: that `autoupdate' was
+# unable to cope with new macros that just swap some of its arguments
+# compared to the old macro.  Fortunately, that was enough to upgrade
+# from Autoconf 1 to Autoconf 2.  (But I have no idea whether the
+# changes in Autoconf 2 were precisely limited by this constraint.)
+#
+#
+# # Second implementation: hooks
+# # ============================
+#
+# The version 2.15 of Autoconf brought a vast number of changes compared
+# to 2.13, so a solution was needed.  One could think of extending the
+# `sed' scripts with specialized code for complex macros.  However, this
+# approach is of course full of flaws:
+#
+# a. the Autoconf maintainers have to write these snippets, which we
+#    just don't want to,
+#
+# b. I really don't think you'll ever manage to handle the quoting of
+#    m4 with a sed script.
+#
+# To satisfy a., let's remark that the code which implements the old
+# features in term of the new feature is exactly the code which should
+# replace the old code.
+#
+# To answer point b, as usual in the history of Autoconf, the answer, at
+# least on the paper, is simple: m4 is the best tool to parse m4, so
+# let's use m4.
+#
+# Therefore the specification is:
+#
+#     I want to be able to tell Autoconf, well, m4, that the macro I
+#     am currently defining is an obsolete macro (so that the user is
+#     warned), and its code is the code to use when running autoconf,
+#     but that the very same code has to be used when running
+#     autoupdate.  To summarize, the interface I want is
+#     `AU_DEFUN(OLD-NAME, NEW-CODE)'.
+#
+#
+# Now for the technical details.
+#
+# When running autoconf, except for the warning, AU_DEFUN is basically
+# AC_DEFUN.
+#
+# When running autoupdate, we want *only* OLD-NAMEs to be expanded.
+# This obviously means that acgeneral.m4 and acspecific.m4 must not be
+# loaded.  Nonetheless, because we want to use a rich set of m4
+# features, m4sugar.m4 is needed.  Please note that the fact that
+# Autoconf's macros are not loaded is positive on two points:
+#
+# - we do get an updated `configure.ac', not a `configure'!
+#
+# - the old macros are replaced by *calls* to the new-macros, not the
+#   body of the new macros, since their body is not defined!!!
+#   (Whoa, that's really beautiful!).
+#
+# Additionally we need to disable the quotes when reading the input for
+# two reasons: first because otherwise `m4' will swallow the quotes of
+# other macros:
+#
+#     NEW([1, 2], 3)
+#     => NEW(1, 2, 3)
+#
+# and second, because we want to update the macro calls which are
+# quoted, i.e., we want
+#
+#     FOO([OLD(1, 2)])
+#     => FOO([NEW([1, 2], [3])])
+#
+# If we don't disable the quotes, only the macros called at the top
+# level would be updated.
+#
+# So, let's disable the quotes.
+#
+# Well, not quite: m4sugar.m4 still needs to use quotes for some macros.
+# Well, in this case, when running in autoupdate code, each macro first
+# reestablishes the quotes, expands itself, and disables the quotes.
+#
+# Thinking a bit more, you realize that in fact, people may use `define',
+# `ifelse' etc. in their files, and you certainly don't want to process
+# them.  Another example is `dnl': you don't want to remove the
+# comments.  You then realize you don't want exactly to import m4sugar:
+# you want to specify when it is enabled (macros active), and disabled.
+# m4sugar provides m4_disable/m4_enable to this end.
+#
+# You're getting close to it.  Now remains one task: how to handle
+# twofold definitions?
+#
+# Remember that the same AU_DEFUN must be understood in two different
+# ways, the AC way, and the AU way.
+#
+# One first solution is to check whether acgeneral.m4 was loaded.  But
+# that's definitely not cute.  Another is simply to install `hooks',
+# that is to say, to keep in some place m4 knows, late `define' to be
+# triggered *only* in AU mode.
+#
+# You first think of designing AU_DEFUN like this:
+#
+# 1. AC_DEFUN(OLD-NAME,
+#	      [Warn the user OLD-NAME is obsolete.
+#	       NEW-CODE])
+#
+# 2. Store for late AU binding([define(OLD_NAME,
+#				[Reestablish the quotes.
+#				 NEW-CODE
+#				 Disable the quotes.])])
+#
+# but this will not work: NEW-CODE probably uses $1, $2 etc. and these
+# guys will be replaced with the argument of `Store for late AU binding'
+# when you call it.
+#
+# I don't think there is a means to avoid this using this technology
+# (remember that $1 etc. are *always* expanded in m4).  You may also try
+# to replace them with $[1] to preserve them for a later evaluation, but
+# if `Store for late AU binding' is properly written, it will remain
+# quoted till the end...
+#
+# You have to change technology.  Since the problem is that `$1'
+# etc. should be `consumed' right away, one solution is to define now a
+# second macro, `AU_OLD-NAME', and to install a hook than binds OLD-NAME
+# to AU_OLD-NAME.  Then, autoupdate.m4 just need to run the hooks.  By
+# the way, the same method was used in autoheader.
+#
+#
+# # Third implementation: m4 namespaces by m4sugar
+# # ==============================================
+#
+# Actually, this implementation was just a clean up of the previous
+# implementation: instead of defining hooks by hand, m4sugar was equipped
+# with `namespaces'.  What are they?
+#
+# Sometimes we want to disable some *set* of macros, and restore them
+# later.  We provide support for this via namespaces.
+#
+# There are basically three characters playing this scene: defining a
+# macro in a namespace, disabling a namespace, and restoring a namespace
+# (i.e., all the definitions it holds).
+#
+# Technically, to define a MACRO in NAMESPACE means to define the macro
+# named `NAMESPACE::MACRO' to the VALUE.  At the same time, we append
+# `undefine(NAME)' in the macro named `m4_disable(NAMESPACE)', and
+# similarly a binding of NAME to the value of `NAMESPACE::MACRO' in
+# `m4_enable(NAMESPACE)'.  These mechanisms allow to bind the macro of
+# NAMESPACE and to unbind them at will.
+#
+# Of course this implementation is really inefficient: m4 has to grow
+# strings which can become quickly huge, which slows it significantly.
+#
+# In particular one should avoid as much as possible to use `define' for
+# temporaries.  Now that `define' has quite a complex meaning, it is an
+# expensive operations that should be limited to macros.  Use
+# `m4_define' for temporaries.
+#
+# Private copies of the macros we used in entering / exiting the m4sugar
+# namespace.  It is much more convenient than fighting with the renamed
+# version of define etc.
+#
+#
+#
+# Those two implementations suffered from serious problems:
+#
+# - namespaces were really expensive, and incurred a major performance
+#   loss on `autoconf' itself, not only `autoupdate'.  One solution
+#   would have been the limit the use of namespaces to `autoupdate', but
+#   that's again some complications on m4sugar, which really doesn't need
+#   this.  So we wanted to get rid of the namespaces.
+#
+# - since the quotes were disabled, autoupdate was sometimes making
+#   wrong guesses, for instance on:
+#
+#     foo([1, 2])
+#
+#   m4 saw 2 arguments: `[1'and `2]'.  A simple solution, somewhat
+#   fragile, is to reestablish the quotes right before all the obsolete
+#   macros, i.e., to use sed so that the previous text becomes
+#
+#     changequote([, ])foo([1, 2])
+#
+#   To this end, one wants to trace the definition of obsolete macros.
+#
+# It was there that the limitations of the namespace approach became
+# painful: because it was a complex machinery playing a lot with the
+# builtins of m4 (hence, quite fragile), tracing was almost impossible.
+#
+#
+# So this approach was dropped.
+#
+#
+# # The fourth implementation: two steps
+# # ====================================
+#
+# If you drop the uses of namespaces, you no longer can compute the
+# updated value, and replace the old call with it simultaneously.
+#
+# Obviously you will use m4 to compute the updated values, but you may
+# use some other tool to achieve the replacement.  Personally, I trust
+# nobody but m4 to parse m4, so below, m4 will perform the two tasks.
+#
+# How can m4 be used to replace *some* macros calls with newer values.
+# Well, that's dead simple: m4 should learn the definitions of obsolete
+# macros, forget its builtins, disable the quotes, and then run on the
+# input file, which amounts to doing this:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# which will result in
+#
+#     dnl The Unbelievable Truth
+#     NEW(1, 2, m4_eval(1 + 2))
+#     NEW([0, 0],
+#	  0)
+#
+# Grpmh.  Two problems.  A minor problem: it would have been much better
+# to have the `m4_eval' computed, and a major problem: you lost the
+# quotation in the result.
+#
+# Let's address the big problem first.  One solution is to define any
+# modern macro to rewrite its calls with the proper quotation, thanks to
+# `$@'.  Again, tracing the `define's makes it possible to know which
+# are these macros, so you input is:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
+#     define([NEW], [[NEW($@)]changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     changequote([, ])NEW([0, 0],
+#	  0)
+#
+# which results in
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2],[m4_eval(1 + 2)])
+#     NEW([0, 0],[0])
+#
+# Our problem is solved, i.e., the first call to `NEW' is properly
+# quoted, but introduced another problem: we changed the layout of the
+# second calls, which can be a drama in the case of huge macro calls
+# (think of `AC_TRY_RUN' for instance).  This example didn't show it,
+# but we also introduced parens to macros which did not have some:
+#
+#     AC_INIT
+#     => AC_INIT()
+#
+# No big deal for the semantics (unless the macro depends upon $#, which
+# is bad), but the users would not be happy.
+#
+# Additionally, we introduced quotes that were not there before, which is
+# OK in most cases, but could change the semantics of the file.
+#
+# Cruel dilemma: we do want the auto-quoting definition of `NEW' when
+# evaluating `OLD', but we don't when we evaluate the second `NEW'.
+# Back to namespaces?
+#
+# No.
+#
+#
+# # Second step: replacement
+# # ------------------------
+#
+# No, as announced above, we will work in two steps: in a first step we
+# compute the updated values, and in a second step we replace them.  Our
+# goal is something like this:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([1, 2], [3])changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# i.e., the new value of `OLD' is precomputed using the auto-quoting
+# definition of `NEW' and the m4 builtins.  We'll see how afterwards,
+# let's finish with the replacement.
+#
+# Of course the solution above is wrong: if there were other calls to
+# `OLD' with different values, we would smash them to the same value.
+# But it is quite easy to generalize the scheme above:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD([1],[2])], [NEW([1, 2], [3])])
+#     define([OLD], [defn([OLD($@)])changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# i.e., for each call to obsolete macros, we build an array `call =>
+# value', and use a macro to dispatch these values.  This results in:
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2], [3])
+#     NEW([0, 0],
+#	  0)
+#
+# In French, we say `Youpi !', which you might roughly translate as
+# `Yippee!'.
+#
+#
+# # First step: computation
+# # -----------------------
+#
+# Let's study the anatomy of the file, and name its sections:
+#
+# prologue
+#     divert(-1)dnl
+#     changequote([, ])
+# values
+#     define([OLD([1],[2])], [NEW([1, 2], [3])])
+# dispatcher
+#     define([OLD], [defn([OLD($@)])changequote()])
+# disabler
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+# input
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+#
+# # Computing the `values' section
+# # ..............................
+#
+# First we need to get the list of all the AU macro uses.  To this end,
+# first get the list of all the AU macros names by tracing `AU_DEFUN' in
+# the initialization of autoconf.  This list is computed in the file
+# `au.txt' below.
+#
+# Then use this list to trace all the AU macro uses in the input.  The
+# goal is obtain in the case of our example:
+#
+#     [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
+#
+# This is the file `values.in' below.
+#
+# We want to evaluate this with only the builtins (in fact m4sugar), the
+# auto-quoting definitions of the new macros (`new.m4'), and the
+# definition of the old macros (`old.m4').  Computing these last two
+# files is easy: it's just a matter of using the right `--trace' option.
+#
+# So the content of `values.in' is:
+#
+#     include($autoconf_dir/m4sugar.m4)
+#     m4_include(new.m4)
+#     m4_include(old.m4)
+#     divert(0)dnl
+#     [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
+#
+# We run m4 on it, which yields:
+#
+#     define([OLD([1],[2])],@<<@NEW([1, 2], [3])@>>@)
+#
+# Transform `@<<@' and `@>>@' into quotes and we get
+#
+#     define([OLD([1],[2])],[NEW([1, 2], [3])])
+#
+# This is `values.m4'.
+#
+#
+# # Computing the `dispatcher' section
+# # ..................................
+#
+# The `prologue', and the `disabler' are simple and need no commenting.
+#
+# To compute the `dispatcher' (`dispatch.m4'), again, it is a simple
+# matter of using the right `--trace'.
+#
+# Finally, the input is not exactly the input file, rather it is the
+# input file with the added `changequote'.  To this end, we build
+# `quote.sed'.
+#
+#
+# # Putting it all together
+# # .......................
+#
+# We build the file `input.m4' which contains:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     include(values.m4)
+#     include(dispatch.m4)
+#     undefine([dnl])
+#     undefine([eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# And we just run m4 on it.  Et voila`, Monsieur !  Mais oui, mais oui.
+#
+# Well, there are a few additional technicalities.  For instance, we
+# rely on `changequote', `ifelse' and `defn', but we don't want to
+# interpret the changequotes of the user, so we simply use another name:
+# `_au_changequote' etc.
+#
+#
+# # Failure of the fourth approach
+# # ------------------------------
+#
+# This approach is heavily based on traces, but then there is an obvious
+# problem: non expanded code will never be seen.  In particular, the body
+# of a `define' definition is not seen, so on the input
+#
+#	  define([idem], [OLD(0, [$1])])
+#
+# autoupdate would never see the `OLD', and wouldn't have updated it.
+# Worse yet, if `idem(0)' was used later, then autoupdate sees that
+# `OLD' is used, computes the result for `OLD(0, 0)' and sets up a
+# dispatcher for `OLD'.  Since there was no computed value for `OLD(0,
+# [$1])', the dispatcher would have replaced with... nothing, leading
+# to
+#
+#	  define([idem], [])
+#
+# With some more thinking, you see that the two step approach is wrong,
+# the namespace approach was much saner.
+#
+# But you learned a lot, in particular you realized that using traces
+# can make it possible to simulate namespaces!
+#
+#
+#
+# # The fifth implementation: m4 namespaces by files
+# # ================================================
+#
+# The fourth implementation demonstrated something unsurprising: you
+# cannot precompute, i.e., the namespace approach was the right one.
+# Still, we no longer want them, they're too expensive.  Let's have a
+# look at the way it worked.
+#
+# When updating
+#
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# you evaluate `input.m4':
+#
+#     divert(-1)
+#     changequote([, ])
+#     define([OLD],
+#     [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
+#     ...
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# where `m4_disable' undefines the m4 and m4sugar, and disables the quotes
+# and comments:
+#
+#     define([m4_disable],
+#     [undefine([__file__])
+#     ...
+#     changecom(#)
+#     changequote()])
+#
+# `m4_enable' does the converse: reestablish quotes and comments
+# --easy--, reestablish m4sugar --easy: just load `m4sugar.m4' again-- and
+# reenable the builtins.  This later task requires that you first save
+# the builtins.  And BTW, the definition above of `m4_disable' cannot
+# work: you undefined `changequote' before using it!  So you need to use
+# your privates copies of the builtins.  Let's introduce three files for
+# this:
+#
+#  `m4save.m4'
+#    moves the m4 builtins into the `_au_' pseudo namespace,
+#  `unm4.m4'
+#    undefines the builtins,
+#  `m4.m4'
+#    restores them.
+#
+# So `input.m4' is:
+#
+#     divert(-1)
+#     changequote([, ])
+#
+#     include([m4save.m4])
+#
+#     # Import AU.
+#     define([OLD],
+#     [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
+#
+#     define([_au_enable],
+#     [_au_changecom([#])
+#     _au_include([m4.m4])
+#     _au_include(m4sugar.m4)])
+#
+#     define([_au_disable],
+#     [# Disable m4sugar.
+#     # Disable the m4 builtins.
+#     _au_include([unm4.m4])
+#     # 1. Disable special characters.
+#     _au_changequote()
+#     _au_changecom()])
+#
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Based on what we learned in the fourth implementation we know that we
+# have to enable the quotes *before* any AU macro, and we know we need
+# to build autoquoting versions of the AC macros.  But the autoquoting
+# AC definitions must be disabled in the rest of the file, and enabled
+# inside AU macros.
+#
+# Using `autoconf --trace' it is easy to build the files
+#
+#   `ac.m4'
+#     define the autoquoting AC fake macros
+#   `disable.m4'
+#     undefine the m4sugar and AC autoquoting macros.
+#   `au.m4'
+#     definitions of the AU macros (such as `OLD' above).
+#
+# Now, `input.m4' is:
+#
+#     divert(-1)
+#     changequote([, ])
+#
+#     include([m4save.m4])
+#     # Import AU.
+#     include([au.m4])
+#
+#     define([_au_enable],
+#     [_au_changecom([#])
+#     _au_include([m4.m4])
+#     _au_include(m4sugar.m4)
+#     _au_include(ac.m4)])
+#
+#     define([_au_disable],
+#     [_au_include([disable.m4])
+#     _au_include([unm4.m4])
+#     # 1. Disable special characters.
+#     _au_changequote()
+#     _au_changecom()])
+#
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     _au_changequote([, ])OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Finally, version V is ready.
+#
+# Well... almost.
+#
+# There is a slight problem that remains: if an AU macro OUTER includes
+# an AU macro INNER, then _au_enable will be run when entering OUTER
+# and when entering INNER (not good, but not too bad yet).  But when
+# getting out of INNER, _au_disable will disable everything while we
+# were still in OUTER.  Badaboom.
+#
+# Therefore _au_enable and _au_disable have to be written to work by
+# pairs: each _au_enable pushdef's _au_enabled, and each _au_disable
+# popdef's _au_enabled.  And of course _au_enable and _au_disable are
+# effective when _au_enabled is *not* defined.
+#
+# Finally, version V' is ready.  And there is much rejoicing.  (And I
+# have free time again.  I think.  Yeah, right.)

+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a

+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+=head1 DESCRIPTION
+
+This package defines channels that can be used in Automake to
+output diagnostics and other messages (via C<msg()>).  It also defines
+some helper function to enable or disable these channels, and some
+shorthand function to output on specific channels.

+=head1 DESCRIPTION
+
+This perl module provides support functions for handling diagnostic
+channels in programs.  Channels can be registered to convey fatal,
+error, warning, or debug messages.  Each channel has various options
+(e.g. is the channel silent, should duplicate messages be removed,
+etc.) that can also be overridden on a per-message basis.

+
+Possible values for the C<uniq_part> options.  This selects the part
+of the message that should be considered when filtering out duplicates.
+If C<UP_LOC_TEXT> is used, the location and the explanation message
+are used for filtering.  If C<UP_TEXT> is used, only the explanation
+message is used (so the same message will be filtered out if it appears
+at different locations).  C<UP_NONE> means that duplicate messages

+Use C<US_GLOBAL> for error messages that should be printed only

+should be printed only once per file.  (Actually, C<Channels> does not
+do this now when files are changed, it relies on you calling
+C<reset_local_duplicates> when this happens.)

+
+=head2 Options
+
+Channels accept the options described below.  These options can be
+passed as a hash to the C<register_channel>, C<setup_channel>, and C<msg>
+functions.  The possible keys, with their default value are:
+
+=over
+
+=item C<type =E<gt> 'warning'>
+
+The type of the channel.  One of C<'debug'>, C<'warning'>, C<'error'>, or
+C<'fatal'>.  Fatal messages abort the program when they are output.
+Error messages update the exit status.  Debug and warning messages are
+harmless, except that warnings are treated as errors if
+C<$warnings_are_errors> is set.
+
+=item C<exit_code =E<gt> 1>
+
+The value to update C<$exit_code> with when a fatal or error message
+is emitted.  C<$exit_code> is also updated for warnings output
+when C<$warnings_are_errors> is set.
+
+=item C<file =E<gt> \*STDERR>
+
+The file where the error should be output.
+
+=item C<silent =E<gt> 0>
+
+Whether the channel should be silent.  Use this do disable a
+category of warning, for instance.
+
+=item C<ordered =E<gt> 1>
+
+Whether, with multi-threaded execution, the message should be queued
+for ordered output.
+
+=item C<uniq_part =E<gt> UP_LOC_TEXT>
+
+The part of the message subject to duplicate filtering.  See the
+documentation for the C<UP_NONE>, C<UP_TEXT>, and C<UP_LOC_TEXT>
+constants above.
+
+C<uniq_part> can also be set to an arbitrary string that will be used
+instead of the message when considering duplicates.
+
+=item C<uniq_scope =E<gt> US_LOCAL>
+
+The scope of duplicate filtering.  See the documentation for the
+C<US_LOCAL>, and C<US_GLOBAL> constants above.
+
+=item C<header =E<gt> ''>
+
+A string to prepend to each message emitted through this channel.
+With partial messages, only the first part will have C<header>
+prepended.
+
+=item C<footer =E<gt> ''>
+
+A string to append to each message emitted through this channel.
+With partial messages, only the final part will have C<footer>
+appended.
+
+=item C<backtrace =E<gt> 0>
+
+Die with a stack backtrace after displaying the message.
+
+=item C<partial =E<gt> 0>
+
+When set, indicates a partial message that should
+be output along with the next message with C<partial> unset.
+Several partial messages can be stacked this way.
+
+Duplicate filtering will apply to the I<global> message resulting from
+all I<partial> messages, using the options from the last (non-partial)
+message.  Linking associated messages is the main reason to use this
+option.
+
+For instance the following messages
+
+  msg 'channel', 'foo:2', 'redefinition of A ...';
+  msg 'channel', 'foo:1', '... A previously defined here';
+  msg 'channel', 'foo:3', 'redefinition of A ...';
+  msg 'channel', 'foo:1', '... A previously defined here';
+
+will result in
+
+ foo:2: redefinition of A ...
+ foo:1: ... A previously defined here
+ foo:3: redefinition of A ...
+
+where the duplicate "I<... A previously defined here>" has been
+filtered out.
+
+Linking these messages using C<partial> as follows will prevent the
+fourth message to disappear.
+
+  msg 'channel', 'foo:2', 'redefinition of A ...', partial => 1;
+  msg 'channel', 'foo:1', '... A previously defined here';
+  msg 'channel', 'foo:3', 'redefinition of A ...', partial => 1;
+  msg 'channel', 'foo:1', '... A previously defined here';
+
+Note that because the stack of C<partial> messages is printed with the
+first non-C<partial> message, most options of C<partial> messages will
+be ignored.

+=item C<msg ($channel, $location, $message, [%options])>
+
+Emit a message on C<$channel>, overriding some options of the channel with
+those specified in C<%options>.  Obviously C<$channel> must have been
+registered with C<register_channel>.
+
+C<$message> is the text of the message, and C<$location> is a location
+associated to the message.
+
+For instance to complain about some unused variable C<mumble>
+declared at line 10 in F<foo.c>, one could do:
+
+  msg 'unused', 'foo.c:10', "unused variable `mumble'";
+
+If channel C<unused> is not silent (and if this message is not a duplicate),
+the following would be output:
+
+  foo.c:10: unused variable `mumble'
+
+C<$location> can also be an instance of C<Autom4te::Location>.  In this
+case, the stack of contexts will be displayed in addition.
+
+If C<$message> contains newline characters, C<$location> is prepended
+to each line.  For instance,
+
+  msg 'error', 'somewhere', "1st line\n2nd line";
+
+becomes
+
+  somewhere: 1st line
+  somewhere: 2nd line
+
+If C<$location> is an empty string, it is replaced by the name of the
+program.  Actually, if you don't use C<%options>, you can even
+elide the empty C<$location>.  Thus
+
+  msg 'fatal', '', 'fatal error';
+  msg 'fatal', 'fatal error';
+
+both print
+
+  progname: fatal error

+=item C<dup_channel_setup ()>, C<drop_channel_setup ()>
+
+Sometimes it is necessary to make temporary modifications to channels.
+For instance one may want to disable a warning while processing a
+particular file, and then restore the initial setup.  These two
+functions make it easy: C<dup_channel_setup ()> saves a copy of the
+current configuration for later restoration by
+C<drop_channel_setup ()>.
+
+You can think of this as a stack of configurations whose first entry
+is the active one.  C<dup_channel_setup ()> duplicates the first
+entry, while C<drop_channel_setup ()> just deletes it.

+=item C<buffer_messages (@types)>, C<flush_messages ()>
+
+By default, when C<msg> is called, messages are processed immediately.
+
+Sometimes it is necessary to delay the output of messages.
+For instance you might want to make diagnostics before
+channels have been completely configured.
+
+After C<buffer_messages(@types)> has been called, messages sent with
+C<msg> to a channel whose type is listed in C<@types> will be stored in a
+list for later processing.
+
+This backlog of messages is processed when C<flush_messages> is
+called, with the current channel options (not the options in effect,
+at the time of C<msg>).  So for instance, if some channel was silenced
+in the meantime, messages to this channel will not be printed.
+
+C<flush_messages> cancels the effect of C<buffer_messages>.  Following
+calls to C<msg> are processed immediately as usual.

+
+
+=head1 DESCRIPTION
+
+C<Autom4te::Struct> exports a single function, C<struct>.
+Given a list of element names and types, and optionally
+a class name, C<struct> creates a Perl 5 class that implements
+a "struct-like" data structure.
+
+The new class is given a constructor method, C<new>, for creating
+struct objects.
+
+Each element in the struct data has an accessor method, which is
+used to assign to the element and to fetch its value.  The
+default accessor can be overridden by declaring a C<sub> of the
+same name in the package.  (See Example 2.)
+
+Each element's type can be scalar, array, hash, or class.
+
+
+=head2 The C<struct()> function
+
+The C<struct> function has three forms of parameter-list.
+
+    struct( CLASS_NAME => [ ELEMENT_LIST ]);
+    struct( CLASS_NAME => { ELEMENT_LIST });
+    struct( ELEMENT_LIST );
+
+The first and second forms explicitly identify the name of the
+class being created.  The third form assumes the current package
+name as the class name.
+
+An object of a class created by the first and third forms is
+based on an array, whereas an object of a class created by the
+second form is based on a hash. The array-based forms will be
+somewhat faster and smaller; the hash-based forms are more
+flexible.
+
+The class created by C<struct> must not be a subclass of another
+class other than C<UNIVERSAL>.
+
+It can, however, be used as a superclass for other classes. To facilitate
+this, the generated constructor method uses a two-argument blessing.
+Furthermore, if the class is hash-based, the key of each element is
+prefixed with the class name (see I<Perl Cookbook>, Recipe 13.12).
+
+A function named C<new> must not be explicitly defined in a class
+created by C<struct>.
+
+The I<ELEMENT_LIST> has the form
+
+    NAME => TYPE, ...
+
+Each name-type pair declares one element of the struct. Each
+element name will be defined as an accessor method unless a
+method by that name is explicitly defined; in the latter case, a
+warning is issued if the warning flag (B<-w>) is set.
+
+
+=head2 Element Types and Accessor Methods
+
+The four element types -- scalar, array, hash, and class -- are
+represented by strings -- C<'$'>, C<'@'>, C<'%'>, and a class name --
+optionally preceded by a C<'*'>.
+
+The accessor method provided by C<struct> for an element depends
+on the declared type of the element.
+
+=over
+
+=item Scalar (C<'$'> or C<'*$'>)
+
+The element is a scalar, and by default is initialized to C<undef>
+(but see L<Initializing with new>).
+
+The accessor's argument, if any, is assigned to the element.
+
+If the element type is C<'$'>, the value of the element (after
+assignment) is returned. If the element type is C<'*$'>, a reference
+to the element is returned.
+
+=item Array (C<'@'> or C<'*@'>)
+
+The element is an array, initialized by default to C<()>.
+
+With no argument, the accessor returns a reference to the
+element's whole array (whether or not the element was
+specified as C<'@'> or C<'*@'>).
+
+With one or two arguments, the first argument is an index
+specifying one element of the array; the second argument, if
+present, is assigned to the array element.  If the element type
+is C<'@'>, the accessor returns the array element value.  If the
+element type is C<'*@'>, a reference to the array element is
+returned.
+
+=item Hash (C<'%'> or C<'*%'>)
+
+The element is a hash, initialized by default to C<()>.
+
+With no argument, the accessor returns a reference to the
+element's whole hash (whether or not the element was
+specified as C<'%'> or C<'*%'>).
+
+With one or two arguments, the first argument is a key specifying
+one element of the hash; the second argument, if present, is
+assigned to the hash element.  If the element type is C<'%'>, the
+accessor returns the hash element value.  If the element type is
+C<'*%'>, a reference to the hash element is returned.
+
+=item Class (C<'Class_Name'> or C<'*Class_Name'>)
+
+The element's value must be a reference blessed to the named
+class or to one of its subclasses. The element is initialized to
+the result of calling the C<new> constructor of the named class.
+
+The accessor's argument, if any, is assigned to the element. The
+accessor will C<croak> if this is not an appropriate object
+reference.
+
+If the element type does not start with a C<'*'>, the accessor
+returns the element value (after assignment). If the element type
+starts with a C<'*'>, a reference to the element itself is returned.
+
+=back
+
+=head2 Initializing with C<new>
+
+C<struct> always creates a constructor called C<new>. That constructor
+may take a list of initializers for the various elements of the new
+struct.
+
+Each initializer is a pair of values: I<element name>C< =E<gt> >I<value>.
+The initializer value for a scalar element is just a scalar value. The
+initializer for an array element is an array reference. The initializer
+for a hash is a hash reference.
+
+The initializer for a class element is also a hash reference, and the
+contents of that hash are passed to the element's own constructor.
+
+See Example 3 below for an example of initialization.
+
+
+=head1 EXAMPLES
+
+=over
+
+=item Example 1
+
+Giving a struct element a class type that is also a struct is how
+structs are nested.  Here, C<timeval> represents a time (seconds and
+microseconds), and C<rusage> has two elements, each of which is of
+type C<timeval>.
+
+    use Autom4te::Struct;
+
+    struct( rusage => {
+        ru_utime => timeval,  # seconds
+        ru_stime => timeval,  # microseconds
+    });
+
+    struct( timeval => [
+        tv_secs  => '$',
+        tv_usecs => '$',
+    ]);
+
+        # create an object:
+    my $t = new rusage;
+
+        # $t->ru_utime and $t->ru_stime are objects of type timeval.
+        # set $t->ru_utime to 100.0 sec and $t->ru_stime to 5.0 sec.
+    $t->ru_utime->tv_secs(100);
+    $t->ru_utime->tv_usecs(0);
+    $t->ru_stime->tv_secs(5);
+    $t->ru_stime->tv_usecs(0);
+
+
+=item Example 2
+
+An accessor function can be redefined in order to provide
+additional checking of values, etc.  Here, we want the C<count>
+element always to be nonnegative, so we redefine the C<count>
+accessor accordingly.
+
+    package MyObj;
+    use Autom4te::Struct;
+
+    # declare the struct
+    struct ( 'MyObj', { count => '$', stuff => '%' } );
+
+    # override the default accessor method for 'count'
+    sub count {
+        my $self = shift;
+        if ( @_ ) {
+            die 'count must be nonnegative' if $_[0] < 0;
+            $self->{'count'} = shift;
+            warn "Too many args to count" if @_;
+        }
+        return $self->{'count'};
+    }
+
+    package main;
+    $x = new MyObj;
+    print "\$x->count(5) = ", $x->count(5), "\n";
+                            # prints '$x->count(5) = 5'
+
+    print "\$x->count = ", $x->count, "\n";
+                            # prints '$x->count = 5'
+
+    print "\$x->count(-5) = ", $x->count(-5), "\n";
+                            # dies due to negative argument!
+
+=item Example 3
+
+The constructor of a generated class can be passed a list
+of I<element>=>I<value> pairs, with which to initialize the struct.
+If no initializer is specified for a particular element, its default
+initialization is performed instead. Initializers for non-existent
+elements are silently ignored.
+
+Note that the initializer for a nested struct is specified
+as an anonymous hash of initializers, which is passed on to the nested
+struct's constructor.
+
+
+    use Autom4te::Struct;
+
+    struct Breed =>
+    {
+        name  => '$',
+        cross => '$',
+    };
+
+    struct Cat =>
+    [
+        name     => '$',
+        kittens  => '@',
+        markings => '%',
+        breed    => 'Breed',
+    ];
+
+
+    my $cat = Cat->new( name     => 'Socks',
+                        kittens  => ['Monica', 'Kenneth'],
+                        markings => { socks=>1, blaze=>"white" },
+                        breed    => { name=>'short-hair', cross=>1 },
+                      );
+
+    print "Once a cat called ", $cat->name, "\n";
+    print "(which was a ", $cat->breed->name, ")\n";
+    print "had two kittens: ", join(' and ', @{$cat->kittens}), "\n";

+=head1 Author and Modification History
+
+Modified by Akim Demaille, 2001-08-03
+
+    Rename as Autom4te::Struct to avoid name clashes with
+    Class::Struct.
+
+    Make it compatible with Perl 5.5.
+
+Modified by Damian Conway, 1999-03-05, v0.58.
+
+    Added handling of hash-like arg list to class ctor.
+
+    Changed to two-argument blessing in ctor to support
+    derivation from created classes.
+
+    Added classname prefixes to keys in hash-based classes
+    (refer to "Perl Cookbook", Recipe 13.12 for rationale).
+
+    Corrected behavior of accessors for '*@' and '*%' struct
+    elements.  Package now implements documented behavior when
+    returning a reference to an entire hash or array element.
+    Previously these were returned as a reference to a reference
+    to the element.
+
+
+Renamed to C<Class::Struct> and modified by Jim Miner, 1997-04-02.
+
+    members() function removed.
+    Documentation corrected and extended.
+    Use of struct() in a subclass prohibited.
+    User definition of accessor allowed.
+    Treatment of '*' in element types corrected.
+    Treatment of classes as element types corrected.
+    Class name to struct() made optional.
+    Diagnostic checks added.
+
+

+Autom4te::XFile - supply object methods for filehandles with error handling
+
+=head1 SYNOPSIS
+
+    use Autom4te::XFile;
+
+    $fh = new Autom4te::XFile;
+    $fh->open ("< file");
+    # No need to check $FH: we died if open failed.
+    print <$fh>;
+    $fh->close;
+    # No need to check the return value of close: we died if it failed.
+
+    $fh = new Autom4te::XFile "> file";
+    # No need to check $FH: we died if new failed.
+    print $fh "bar\n";
+    $fh->close;
+
+    $fh = new Autom4te::XFile "file", "r";
+    # No need to check $FH: we died if new failed.
+    defined $fh
+    print <$fh>;
+    undef $fh;   # automatically closes the file and checks for errors.
+
+    $fh = new Autom4te::XFile "file", O_WRONLY | O_APPEND;
+    # No need to check $FH: we died if new failed.
+    print $fh "corge\n";
+
+    $pos = $fh->getpos;
+    $fh->setpos ($pos);
+
+    undef $fh;   # automatically closes the file and checks for errors.
+
+    autoflush STDOUT 1;
+
+=head1 DESCRIPTION
+
+C<Autom4te::XFile> inherits from C<IO::File>.  It provides the method
+C<name> returning the file name.  It provides dying versions of the
+methods C<close>, C<lock> (corresponding to C<flock>), C<new>,
+C<open>, C<seek>, and C<truncate>.  It also overrides the C<getline>
+and C<getlines> methods to translate C<\r\n> to C<\n>.

+
+Basic Installation
+==================
+
+   Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.  Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the `make install' phase executed with root
+     privileges.
+
+  5. Optionally, type `make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior `make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type `make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide `make
+     distcheck', which can by used by developers to test that all other
+     targets like `make install' and `make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.  This
+is known as a "VPATH" build.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of `make' will be.  For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run

+# Fortran vs. Fortran 77:
+#   This file contains macros for both "Fortran 77" and "Fortran", where
+# the former is the "classic" autoconf Fortran interface and is intended
+# for legacy F77 codes, while the latter is intended to support newer Fortran
+# dialects.  Fortran 77 uses environment variables F77, FFLAGS, and FLIBS,
+# while Fortran uses FC, FCFLAGS, and FCLIBS.  For each user-callable AC_*
+# macro, there is generally both an F77 and an FC version, where both versions
+# share the same _AC_*_FC_* backend.  This backend macro requires that
+# the appropriate language be AC_LANG_PUSH'ed, and uses _AC_LANG_ABBREV and
+# _AC_LANG_PREFIX in order to name cache and environment variables, etc.

+# What is technically happening is that the Fortran libraries provide

+# Check whether `mkdir -p' is known to be thread-safe, and fall back to
+# install-sh -d otherwise.
+#
+# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
+# created by `make install' are always world readable, even if the
+# installer happens to have an overly restrictive umask (e.g. 077).
+# This was a mistake.  There are at least two reasons why we must not
+# use `-m 0755':
+#   - it causes special bits like SGID to be ignored,
+#   - it may be too restrictive (some setups expect 775 directories).
+#
+# Do not use -m 0755 and let people choose whatever they expect by
+# setting umask.
+#
+# We cannot accept any implementation of `mkdir' that recognizes `-p'.
+# Some implementations (such as Solaris 8's) are vulnerable to race conditions:
+# if a parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
+# concurrently, both version can detect that a/ is missing, but only
+# one can create it and the other will error out.  Consequently we
+# restrict ourselves to known race-free implementations.
+#
+# Automake used to define mkdir_p as `mkdir -p .', in order to
+# allow $(mkdir_p) to be used without argument.  As in
+#   $(mkdir_p) $(somedir)
+# where $(somedir) is conditionally defined.  However we don't do
+# that for MKDIR_P.
+#  1. before we restricted the check to GNU mkdir, `mkdir -p .' was
+#     reported to fail in read-only directories.  The system where this
+#     happened has been forgotten.
+#  2. in practice we call $(MKDIR_P) on directories such as
+#       $(MKDIR_P) "$(DESTDIR)$(somedir)"
+#     and we don't want to create $(DESTDIR) if $(somedir) is empty.
+#     To support the latter case, we have to write
+#       test -z "$(somedir)" || $(MKDIR_P) "$(DESTDIR)$(somedir)"
+#     so $(MKDIR_P) always has an argument.
+#     We will have better chances of detecting a missing test if
+#     $(MKDIR_P) complains about missing arguments.
+#  3. $(MKDIR_P) is named after `mkdir -p' and we don't expect this
+#     to accept no argument.
+#  4. having something like `mkdir .' in the output is unsightly.

+# This file handles about all the preparation aspects for
+# `config.status': registering the configuration files, the headers,
+# the links, and the commands `config.status' will run.  There is a
+# little mixture though of things actually handled by `configure',
+# such as running the `configure' in the sub directories.  Minor
+# detail.
+#
+# There are two kinds of commands:
+#
+# COMMANDS:
+#
+#   They are output into `config.status' via a quoted here doc.  These
+#   commands are always associated to a tag which the user can use to
+#   tell `config.status' what are the commands she wants to run.
+#
+# INIT-CMDS:
+#
+#   They are output via an *unquoted* here-doc.  As a consequence $var
+#   will be output as the value of VAR.  This is typically used by
+#   `configure' to give `config.status' some variables it needs to run
+#   the COMMANDS.  At the difference of COMMANDS, the INIT-CMDS are
+#   always run.
+#
+#
+# Honorable members of this family are AC_CONFIG_FILES,
+# AC_CONFIG_HEADERS, AC_CONFIG_LINKS and AC_CONFIG_COMMANDS.  Bad boys
+# are AC_LINK_FILES, AC_OUTPUT_COMMANDS and AC_OUTPUT when used with
+# arguments.  False members are AC_CONFIG_SRCDIR, AC_CONFIG_SUBDIRS
+# and AC_CONFIG_AUX_DIR.  Cousins are AC_CONFIG_COMMANDS_PRE and
+# AC_CONFIG_COMMANDS_POST.

+## Type existence.  ##
+## ---------------- ##
+
+# ---------------- #
+# General checks.  #
+# ---------------- #
+
+# Up to 2.13 included, Autoconf used to provide the macro
+#
+#    AC_CHECK_TYPE(TYPE, DEFAULT)
+#
+# Since, it provides another version which fits better with the other
+# AC_CHECK_ families:
+#
+#    AC_CHECK_TYPE(TYPE,
+#		   [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
+#		   [INCLUDES = DEFAULT-INCLUDES])
+#
+# In order to provide backward compatibility, the new scheme is
+# implemented as _AC_CHECK_TYPE_NEW, the old scheme as _AC_CHECK_TYPE_OLD,
+# and AC_CHECK_TYPE branches to one or the other, depending upon its
+# arguments.
+
+
+# _AC_CHECK_TYPE_NEW_BODY
+# -----------------------
+# Shell function body for _AC_CHECK_TYPE_NEW.  This macro implements the
+# former task of AC_CHECK_TYPE, with one big difference though: AC_CHECK_TYPE
+# used to grep in the headers, which, BTW, led to many problems until the
+# extended regular expression was correct and did not give false positives.
+# It turned out there are even portability issues with egrep...
+#
+# The most obvious way to check for a TYPE is just to compile a variable
+# definition:
+#
+#	  TYPE my_var;
+#
+# (TYPE being the second parameter to the shell function, hence $[]2 in m4).
+# Unfortunately this does not work for const qualified types in C++, where
+# you need an initializer.  So you think of
+#
+#	  TYPE my_var = (TYPE) 0;
+#
+# Unfortunately, again, this is not valid for some C++ classes.
+#
+# Then you look for another scheme.  For instance you think of declaring
+# a function which uses a parameter of type TYPE:
+#
+#	  int foo (TYPE param);
+#
+# but of course you soon realize this does not make it with K&R
+# compilers.  And by no ways you want to
+#
+#	  int foo (param)
+#	    TYPE param
+#	  { ; }
+#
+# since this time it's C++ who is not happy.
+#
+# Don't even think of the return type of a function, since K&R cries
+# there too.  So you start thinking of declaring a *pointer* to this TYPE:
+#
+#	  TYPE *p;
+#
+# but you know fairly well that this is legal in C for aggregates which
+# are unknown (TYPE = struct does-not-exist).
+#
+# Then you think of using sizeof to make sure the TYPE is really
+# defined:
+#
+#	  sizeof (TYPE);
+#
+# But this succeeds if TYPE is a variable: you get the size of the
+# variable's type!!!
+#
+# So, to filter out the last possibility, you try this too:
+#
+#	  sizeof ((TYPE));
+#
+# This fails if TYPE is a type, but succeeds if TYPE is actually a variable.
+#
+# Also note that we use
+#
+#	  if (sizeof (TYPE))
+#
+# to `read' sizeof (to avoid warnings), while not depending on its type
+# (not necessarily size_t etc.).
+#
+# C++ disallows defining types inside `sizeof ()', but that's OK,
+# since we don't want to consider unnamed structs to be types for C++,
+# precisely because they don't work in cases like that.

+dnl Catching signals correctly:
+dnl
+dnl The first idea was: trap the signal, send it to all spawned jobs,
+dnl then reset the handler and reraise the signal for ourselves.
+dnl However, before exiting, ksh will then send the signal to all
+dnl process group members, potentially killing the outer testsuite
+dnl and/or the 'make' process driving us.
+dnl So now the strategy is: trap the signal, send it to all spawned jobs,
+dnl then exit the script with the right status.
+dnl
+dnl In order to let the jobs know about the signal, we cannot just send it
+dnl to the current process group (kill $SIG 0), for the same reason as above.
+dnl Also, it does not reliably stop the suite to send the signal to the
+dnl spawned processes, because they might not transport it further
+dnl (maybe this can be fixed?).
+dnl
+dnl So what we do is enable shell job control if available, which causes the
+dnl shell to start each parallel task as its own shell job, thus as a new
+dnl process group leader.  We then send the signal to all new process groups.

+# _AT_DECIDE_TRACEABLE(COMMANDS)
+# ------------------------------
+# Worker for _AT_CHECK that expands to shell code.  If COMMANDS are safe to
+# trace with `set -x', the shell code will evaluate to true.  Otherwise,
+# the shell code will print a message stating an aspect of COMMANDS that makes
+# tracing them unsafe, and evaluate to false.
+#
+# Tracing COMMANDS is not safe if they contain a command that spans multiple
+# lines.  When the test suite user passes `-x' or `--trace', the test suite
+# precedes every command with a `set -x'.  Since most tests expect a specific
+# stderr, if only to confirm that it is empty, the test suite filters ^+ from
+# the captured stderr before comparing with the expected stderr.  If a command
+# spans multiple lines, so will its trace, but a `+' only prefixes the first
+# line of that trace:
+#
+# $ echo 'foo
+# bar'
+# => stdout
+# foo
+# bar
+# => stderr
+# + foo
+# bar
+#
+# In a subset of cases, one could filter such extended shell traces from
+# stderr.  Since test commands spanning several lines are rare, I chose
+# instead to simply not trace COMMANDS that could yield multiple trace lines.
+# Distinguishing such COMMANDS became the task at hand.
+#
+# These features may cause a shell command to span multiple lines:
+#
+# (a) A quoted literal newline.
+# Example:
+#   echo foo'
+#   'bar
+# M4 is a hostile language for the job of parsing COMMANDS to determine whether
+# each literal newline is quoted, so we simply disable tracing for all COMMANDS
+# that bear literal newlines.
+#
+# (b) A command substitution not subject to word splitting.
+# Example:
+#   var=$(printf 'foo\nbar')
+# Example:
+#   echo "`printf 'foo\\nbar`"
+# One cannot know in general the number of lines a command substitution will
+# yield without executing the substituted command.  As such, we disable tracing
+# for all COMMANDS containing these constructs.
+#
+# (c) A parameter expansion not subject to word splitting.
+# Example:
+#   var=foo'
+#   'bar
+#   echo "$var"
+# Parameter expansions appear in COMMANDS with much greater frequency than do
+# newlines and command substitutions, so disabling tracing for all such
+# COMMANDS would much more substantially devalue `testsuite -x'.  To determine
+# which parameter expansions yield multiple lines, we escape all ``', `"',
+# and `\' in a copy of COMMANDS and expand that string within double quotes
+# at runtime.  If the result of that expansion contains multiple lines, the
+# test suite disables tracing for the command in question.
+#
+# This method leads the test suite to expand some parameters that the shell
+# itself will never expand due to single-quotes or backslash escapes.  This is
+# not a problem for `$foo' expansions, which will simply yield the empty string
+# or some unrelated value.  A `${...}' expansion could actually form invalid
+# shell code, however; consider `${=foo}'.  Therefore, we disable tracing for
+# all COMMANDS containing `${...}'.  This affects few COMMANDS.
+#
+# This macro falls in a very hot path; the Autoconf test suite expands it 1640
+# times as of this writing.  To give a sense of the impact of the heuristics I
+# just described, the test suite preemptively disables tracing for 31 of those,
+# and 268 contain parameter expansions that require runtime evaluation.  The

+# but we must group COMMANDS as it is not limited to a single command, and
+# then the shells will save the traces in at-stderr. So we have to filter
+# them out when checking stderr, and we must send them into the test suite's
+# stderr to honor -x properly. Since only the first line of the trace of a
+# multiline command starts with a `+', and I know of no straightforward way to
+# filter out the unadorned trace lines, we disable shell tracing entirely for
+# commands that could span multiple lines.
+#
+# Limiting COMMANDS to a single command is not good either, since then
+# the user herself would use {} or (), and then we face the same problem.
+#
+# But then, there is no point in running

+#   ( $at_traceon { $1 ; } >at-stdout 2>at-stder1 )

+# In M4 1.4.x, every byte of $@ is rescanned.  This means that an
+# algorithm on n arguments that recurses with one less argument each
+# iteration will scan n * (n + 1) / 2 arguments, for O(n^2) time.  In
+# M4 1.6, this was fixed so that $@ is only scanned once, then
+# back-references are made to information stored about the scan.
+# Thus, n iterations need only scan n arguments, for O(n) time.
+# Additionally, in M4 1.4.x, recursive algorithms did not clean up
+# memory very well, requiring O(n^2) memory rather than O(n) for n
+# iterations.
+#
+# This file is designed to overcome the quadratic nature of $@
+# recursion by writing a variant of m4_foreach that uses m4_for rather
+# than $@ recursion to operate on the list.  This involves more macro
+# expansions, but avoids the need to rescan a quadratic number of
+# arguments, making these replacements very attractive for M4 1.4.x.
+# On the other hand, in any version of M4, expanding additional macros
+# costs additional time; therefore, in M4 1.6, where $@ recursion uses
+# fewer macros, these replacements actually pessimize performance.
+# Additionally, the use of $10 to mean the tenth argument violates
+# POSIX; although all versions of m4 1.4.x support this meaning, a
+# future m4 version may switch to take it as the first argument
+# concatenated with a literal 0, so the implementations in this file
+# are not future-proof.  Thus, this file is conditionally included as
+# part of m4_init(), only when it is detected that M4 probably has
+# quadratic behavior (ie. it lacks the macro __m4_version__).
+#
+# Please keep this file in sync with m4sugar.m4.
+
+# _m4_foreach(PRE, POST, IGNORED, ARG...)
+# ---------------------------------------
+# Form the common basis of the m4_foreach and m4_map macros.  For each
+# ARG, expand PRE[ARG]POST[].  The IGNORED argument makes recursion
+# easier, and must be supplied rather than implicit.
+#
+# This version minimizes the number of times that $@ is evaluated by
+# using m4_for to generate a boilerplate into _m4_f then passing $@ to
+# that temporary macro.  Thus, the recursion is done in m4_for without
+# reparsing any user input, and is not quadratic.  For an idea of how
+# this works, note that m4_foreach(i,[1,2],[i]) calls
+#   _m4_foreach([m4_define([i],],[)i],[],[1],[2])
+# which defines _m4_f:
+#   $1[$4]$2[]$1[$5]$2[]_m4_popdef([_m4_f])
+# then calls _m4_f([m4_define([i],],[)i],[],[1],[2]) for a net result:

+#
+# A help string is made up of a "left hand side" (LHS) and a "right

+# must be complex to safely deal with ``, while a simpler
+# expression IF-SIMPLE-REF can be used if the indirection
+# involves only shell variable expansion (as in ${varname}).
+#
+# EXPRESSION is treated as a literal if it results in the same
+# interpretation whether it is unquoted or contained within double
+# quotes, with the exception that whitespace is ignored (on the
+# assumption that it will be flattened to _).  Therefore, neither `\$'
+# nor `a''b' is a literal, since both backslash and single quotes have
+# different quoting behavior in the two contexts; and `a*' is not a
+# literal, because it has different globbing.  Note, however, that
+# while `${a+b}' is neither a literal nor a simple ref, `a+b' is a
+# literal.  This macro is an *approximation*: it is possible that
+# there are some EXPRESSIONs which the shell would treat as literals,
+# but which this macro does not recognize.
+#
+# Why do we reject EXPRESSION expanding with `[' or `]' as a literal?
+# Because AS_TR_SH is MUCH faster if it can use m4_translit on literals
+# instead of m4_bpatsubst; but m4_translit is much tougher to do safely
+# if `[' is translated.  That, and file globbing matters.
+#
+# Note that the quadrigraph @S|@ can result in non-literals, but outright
+# rejecting all @ would make AC_INIT complain on its bug report address.
+#
+# We used to use m4_bmatch(m4_quote($1), [[`$]], [$3], [$2]), but
+# profiling shows that it is faster to use m4_translit.
+#
+# Because the translit is stripping quotes, it must also neutralize
+# anything that might be in a macro name, as well as comments, commas,
+# or unbalanced parentheses.  Valid shell variable characters and
+# unambiguous literal characters are deleted (`a.b'), and remaining
+# characters are normalized into `$' if they can form simple refs
+# (${a}), `+' if they can potentially form literals (a+b), ``' if they
+# can interfere with m4 parsing, or left alone otherwise.  If both `$'
+# and `+' are left, it is treated as a complex reference (${a+b}),
+# even though it could technically be a simple reference (${a}+b).
+# _AS_LITERAL_IF_ only has to check for an empty string after removing
+# one of the two normalized characters.
+#
+# Rather than expand m4_defn every time AS_LITERAL_IF is expanded, we
+# inline its expansion up front.  _AS_LITERAL_IF expands to the name
+# of a macro that takes three arguments: IF-SIMPLE-REF,
+# IF-NOT-LITERAL, IF-LITERAL.  It also takes an optional argument of
+# any additional characters to allow as literals (useful for AS_TR_SH

+# Now, just replace the `$2' with `m4_quote($2)' in the outer `m4_if'
+# to improve robustness, and you come up with a nice implementation
+# that doesn't require extra parentheses in the user's LIST.
+#
+# But wait -  now the algorithm is quadratic, because every recursion of
+# the algorithm keeps the entire LIST and merely adds another m4_shift to
+# the quoted text.  If the user has a lot of elements in LIST, you can
+# bring the system to its knees with the memory m4 then requires, or trip
+# the m4 --nesting-limit recursion factor.  The only way to avoid
+# quadratic growth is ensure m4_shift is expanded prior to the recursion.
+# Hence the design below.
+#
+# The M4 manual now includes a chapter devoted to this issue, with
+# the lessons learned from m4sugar.  And still, this design is only

+## 10. Defining macros with bells and whistles.  ##
+## --------------------------------------------- ##
+
+# `m4_defun' is basically `m4_define' but it equips the macro with the
+# needed machinery for `m4_require'.  A macro must be m4_defun'd if
+# either it is m4_require'd, or it m4_require's.
+#
+# Two things deserve attention and are detailed below:
+#  1. Implementation of m4_require
+#  2. Keeping track of the expansion stack
+#
+# 1. Implementation of m4_require
+# ===============================
+#
+# Of course m4_defun calls m4_provide, so that a macro which has
+# been expanded is not expanded again when m4_require'd, but the
+# difficult part is the proper expansion of macros when they are
+# m4_require'd.
+#
+# The implementation is based on three ideas, (i) using diversions to
+# prepare the expansion of the macro and its dependencies (by Franc,ois
+# Pinard), (ii) expand the most recently m4_require'd macros _after_
+# the previous macros (by Axel Thimm), and (iii) track instances of
+# provide before require (by Eric Blake).
+#
+#
+# The first idea: why use diversions?
+# -----------------------------------
+#
+# When a macro requires another, the other macro is expanded in new
+# diversion, GROW.  When the outer macro is fully expanded, we first
+# undivert the most nested diversions (GROW - 1...), and finally
+# undivert GROW.  To understand why we need several diversions,
+# consider the following example:
+#
+# | m4_defun([TEST1], [Test...m4_require([TEST2])1])
+# | m4_defun([TEST2], [Test...m4_require([TEST3])2])
+# | m4_defun([TEST3], [Test...3])
+#
+# Because m4_require is not required to be first in the outer macros, we
+# must keep the expansions of the various levels of m4_require separated.
+# Right before executing the epilogue of TEST1, we have:
+#
+#	   GROW - 2: Test...3
+#	   GROW - 1: Test...2
+#	   GROW:     Test...1
+#	   BODY:
+#
+# Finally the epilogue of TEST1 undiverts GROW - 2, GROW - 1, and
+# GROW into the regular flow, BODY.
+#
+#	   GROW - 2:
+#	   GROW - 1:
+#	   GROW:
+#	   BODY:        Test...3; Test...2; Test...1
+#
+# (The semicolons are here for clarification, but of course are not
+# emitted.)  This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
+# implement.
+#
+#
+# The second idea: first required first out
+# -----------------------------------------
+#
+# The natural implementation of the idea above is buggy and produces
+# very surprising results in some situations.  Let's consider the
+# following example to explain the bug:
+#
+# | m4_defun([TEST1],  [m4_require([TEST2a])m4_require([TEST2b])])
+# | m4_defun([TEST2a], [])
+# | m4_defun([TEST2b], [m4_require([TEST3])])
+# | m4_defun([TEST3],  [m4_require([TEST2a])])
+# |
+# | AC_INIT
+# | TEST1
+#
+# The dependencies between the macros are:
+#
+#		 3 --- 2b
+#		/        \              is m4_require'd by
+#	       /          \       left -------------------- right
+#	    2a ------------ 1
+#
+# If you strictly apply the rules given in the previous section you get:
+#
+#	   GROW - 2: TEST3
+#	   GROW - 1: TEST2a; TEST2b
+#	   GROW:     TEST1
+#	   BODY:
+#
+# (TEST2a, although required by TEST3 is not expanded in GROW - 3
+# because is has already been expanded before in GROW - 1, so it has
+# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
+# the stack of diversions, you get:
+#
+#	   GROW - 2:
+#	   GROW - 1:
+#	   GROW:
+#	   BODY:        TEST3; TEST2a; TEST2b; TEST1
+#
+# i.e., TEST2a is expanded after TEST3 although the latter required the
+# former.
+#
+# Starting from 2.50, we use an implementation provided by Axel Thimm.
+# The idea is simple: the order in which macros are emitted must be the
+# same as the one in which macros are expanded.  (The bug above can
+# indeed be described as: a macro has been m4_provide'd before its
+# dependent, but it is emitted after: the lack of correlation between
+# emission and expansion order is guilty).
+#
+# How to do that?  You keep the stack of diversions to elaborate the
+# macros, but each time a macro is fully expanded, emit it immediately.
+#
+# In the example above, when TEST2a is expanded, but it's epilogue is
+# not run yet, you have:
+#
+#	   GROW - 2:
+#	   GROW - 1: TEST2a
+#	   GROW:     Elaboration of TEST1
+#	   BODY:
+#
+# The epilogue of TEST2a emits it immediately:
+#
+#	   GROW - 2:

+# details.
+#
+#
+# The Axel Thimm implementation at work
+# -------------------------------------
+#
+# We consider the macros above, and this configure.ac:
+#
+#	    AC_INIT
+#	    TEST1
+#
+# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and
+# m4_require at hand to follow the steps.
+#
+# This implementation tries not to assume that the current diversion is
+# BODY, so as soon as a macro (m4_defun'd) is expanded, we first
+# record the current diversion under the name _m4_divert_dump (denoted
+# DUMP below for short).  This introduces an important difference with
+# the previous versions of Autoconf: you cannot use m4_require if you
+# are not inside an m4_defun'd macro, and especially, you cannot
+# m4_require directly from the top level.
+#
+# We have not tried to simulate the old behavior (better yet, we
+# diagnose it), because it is too dangerous: a macro m4_require'd from
+# the top level is expanded before the body of `configure', i.e., before
+# any other test was run.  I let you imagine the result of requiring
+# AC_STDC_HEADERS for instance, before AC_PROG_CC was actually run....
+#
+# After AC_INIT was run, the current diversion is BODY.
+# * AC_INIT was run
+#   DUMP:                undefined
+#   diversion stack:     BODY |-
+#
+# * TEST1 is expanded
+# The prologue of TEST1 sets _m4_divert_dump, which is the diversion
+# where the current elaboration will be dumped, to the current
+# diversion.  It also m4_divert_push to GROW, where the full
+# expansion of TEST1 and its dependencies will be elaborated.
+#   DUMP:        BODY
+#   BODY:        empty
+#   diversions:  GROW, BODY |-
+#
+# * TEST1 requires TEST2a
+# _m4_require_call m4_divert_pushes another temporary diversion,
+# GROW - 1, and expands TEST2a in there.
+#   DUMP:        BODY
+#   BODY:        empty
+#   GROW - 1:    TEST2a
+#   diversions:  GROW - 1, GROW, BODY |-
+# Then the content of the temporary diversion is moved to DUMP and the
+# temporary diversion is popped.
+#   DUMP:        BODY
+#   BODY:        TEST2a
+#   diversions:  GROW, BODY |-
+#
+# * TEST1 requires TEST2b
+# Again, _m4_require_call pushes GROW - 1 and heads to expand TEST2b.
+#   DUMP:        BODY
+#   BODY:        TEST2a
+#   diversions:  GROW - 1, GROW, BODY |-
+#
+# * TEST2b requires TEST3
+# _m4_require_call pushes GROW - 2 and expands TEST3 here.
+# (TEST3 requires TEST2a, but TEST2a has already been m4_provide'd, so
+# nothing happens.)
+#   DUMP:        BODY
+#   BODY:        TEST2a
+#   GROW - 2:    TEST3
+#   diversions:  GROW - 2, GROW - 1, GROW, BODY |-
+# Then the diversion is appended to DUMP, and popped.
+#   DUMP:        BODY
+#   BODY:        TEST2a; TEST3
+#   diversions:  GROW - 1, GROW, BODY |-
+#
+# * TEST1 requires TEST2b (contd.)
+# The content of TEST2b is expanded...
+#   DUMP:        BODY
+#   BODY:        TEST2a; TEST3
+#   GROW - 1:    TEST2b,
+#   diversions:  GROW - 1, GROW, BODY |-
+# ... and moved to DUMP.
+#   DUMP:        BODY
+#   BODY:        TEST2a; TEST3; TEST2b
+#   diversions:  GROW, BODY |-
+#
+# * TEST1 is expanded: epilogue
+# TEST1's own content is in GROW...
+#   DUMP:        BODY
+#   BODY:        TEST2a; TEST3; TEST2b
+#   GROW:        TEST1
+#   diversions:  BODY |-
+# ... and it's epilogue moves it to DUMP and then undefines DUMP.
+#   DUMP:       undefined
+#   BODY:       TEST2a; TEST3; TEST2b; TEST1
+#   diversions: BODY |-
+#
+#
+# The third idea: track macros provided before they were required
+# ---------------------------------------------------------------
+#
+# Using just the first two ideas, Autoconf 2.50 through 2.63 still had
+# a subtle bug for more than seven years.  Let's consider the
+# following example to explain the bug:
+#
+# | m4_defun([TEST1], [1])
+# | m4_defun([TEST2], [2[]m4_require([TEST1])])
+# | m4_defun([TEST3], [3 TEST1 m4_require([TEST2])])
+# | TEST3
+#
+# After the prologue of TEST3, we are collecting text in GROW with the
+# intent of dumping it in BODY during the epilogue.  Next, we
+# encounter the direct invocation of TEST1, which provides the macro
+# in place in GROW.  From there, we encounter a requirement for TEST2,
+# which must be collected in a new diversion.  While expanding TEST2,
+# we encounter a requirement for TEST1, but since it has already been
+# expanded, the Axel Thimm algorithm states that we can treat it as a
+# no-op.  But that would lead to an end result of `2 3 1', meaning
+# that we have once again output a macro (TEST2) prior to its
+# requirements (TEST1).
+#
+# The problem can only occur if a single defun'd macro first provides,
+# then later indirectly requires, the same macro.  Note that directly
+# expanding then requiring a macro is okay: because the dependency was
+# met, the require phase can be a no-op.  For that matter, the outer
+# macro can even require two helpers, where the first helper expands
+# the macro, and the second helper indirectly requires the macro.
+# Out-of-order expansion is only present if the inner macro is
+# required by something that will be hoisted in front of where the
+# direct expansion occurred.  In other words, we must be careful not
+# to warn on:
+#
+# | m4_defun([TEST4], [4])
+# | m4_defun([TEST5], [5 TEST4 m4_require([TEST4])])
+# | TEST5 => 5 4
+#
+# or even the more complex:
+#
+# | m4_defun([TEST6], [6])
+# | m4_defun([TEST7], [7 TEST6])
+# | m4_defun([TEST8], [8 m4_require([TEST6])])
+# | m4_defun([TEST9], [9 m4_require([TEST8])])
+# | m4_defun([TEST10], [10 m4_require([TEST7]) m4_require([TEST9])])
+# | TEST10 => 7 6 8 9 10
+#
+# So, to detect whether a require was direct or indirect, m4_defun and
+# m4_require track the name of the macro that caused a diversion to be
+# created (using the stack _m4_diverting, coupled with an O(1) lookup
+# _m4_diverting([NAME])), and m4_provide stores the name associated
+# with the diversion at which a macro was provided.  A require call is
+# direct if it occurs within the same diversion where the macro was
+# provided, or if the diversion associated with the providing context
+# has been collected.
+#
+# The implementation of the warning involves tracking the set of
+# macros which have been provided since the start of the outermost
+# defun'd macro (the set is named _m4_provide).  When starting an
+# outermost macro, the set is emptied; when a macro is provided, it is
+# added to the set; when require expands the body of a macro, it is
+# removed from the set; and when a macro is indirectly required, the
+# set is checked.  If a macro is in the set, then it has been provided
+# before it was required, and we satisfy dependencies by expanding the
+# macro as if it had never been provided; in the example given above,
+# this means we now output `1 2 3 1'.  Meanwhile, a warning is issued
+# to inform the user that her macros trigger the bug in older autoconf
+# versions, and that her output file now contains redundant contents
+# (and possibly new problems, if the repeated macro was not
+# idempotent).  Meanwhile, macros defined by m4_defun_once instead of
+# m4_defun are idempotent, avoiding any warning or duplicate output.
+#
+#
+# 2. Keeping track of the expansion stack
+# =======================================
+#
+# When M4 expansion goes wrong it is often extremely hard to find the
+# path amongst macros that drove to the failure.  What is needed is
+# the stack of macro `calls'. One could imagine that GNU M4 would
+# maintain a stack of macro expansions, unfortunately it doesn't, so
+# we do it by hand.  This is of course extremely costly, but the help
+# this stack provides is worth it.  Nevertheless to limit the
+# performance penalty this is implemented only for m4_defun'd macros,
+# not for define'd macros.
+#
+# Each time we enter an m4_defun'd macros, we add a definition in
+# _m4_expansion_stack, and when we exit the macro, we remove it (thanks
+# to pushdef/popdef).  m4_stack_foreach is used to print the expansion
+# stack in the rare cases when it's needed.
+#
+# In addition, we want to detect circular m4_require dependencies.
+# Each time we expand a macro FOO we define _m4_expanding(FOO); and
+# m4_require(BAR) simply checks whether _m4_expanding(BAR) is defined.
+
+
+# m4_expansion_stack
+# ------------------
+# Expands to the entire contents of the expansion stack.  The caller
+# must supply a trailing newline.  This macro always prints a
+# location; check whether _m4_expansion_stack is defined to filter out
+# the case when no defun'd macro is in force.
+m4_define([m4_expansion_stack],
+[m4_stack_foreach_sep_lifo([_$0], [_$0_entry(], [)
+])m4_location[: the top level]])

+## 15. Set handling.  ##
+## ------------------ ##
+
+# Autoconf likes to create arbitrarily large sets; for example, as of
+# this writing, the configure.ac for coreutils tracks a set of more
+# than 400 AC_SUBST.  How do we track all of these set members,
+# without introducing duplicates?  We could use m4_append_uniq, with
+# the set NAME residing in the contents of the macro NAME.
+# Unfortunately, m4_append_uniq is quadratic for set creation, because
+# it costs O(n) to search the string for each of O(n) insertions; not
+# to mention that with m4 1.4.x, even using m4_append is slow, costing
+# O(n) rather than O(1) per insertion.  Other set operations, not used
+# by Autoconf but still possible by manipulation of the definition
+# tracked in macro NAME, include O(n) deletion of one element and O(n)
+# computation of set size.  Because the set is exposed to the user via
+# the definition of a single macro, we cannot cache any data about the
+# set without risking the cache being invalidated by the user
+# redefining NAME.
+#
+# Can we do better?  Yes, because m4 gives us an O(1) search function
+# for free: ifdef.  Additionally, even m4 1.4.x gives us an O(1)
+# insert operation for free: pushdef.  But to use these, we must
+# represent the set via a group of macros; to keep the set consistent,
+# we must hide the set so that the user can only manipulate it through
+# accessor macros.  The contents of the set are maintained through two
+# access points; _m4_set([name]) is a pushdef stack of values in the
+# set, useful for O(n) traversal of the set contents; while the
+# existence of _m4_set([name],value) with no particular value is
+# useful for O(1) querying of set membership.  And since the user
+# cannot externally manipulate the set, we are free to add additional
+# caching macros for other performance improvements.  Deletion can be
+# O(1) per element rather than O(n), by reworking the definition of
+# _m4_set([name],value) to be 0 or 1 based on current membership, and
+# adding _m4_set_cleanup(name) to defer the O(n) cleanup of
+# _m4_set([name]) until we have another reason to do an O(n)
+# traversal.  The existence of _m4_set_cleanup(name) can then be used
+# elsewhere to determine if we must dereference _m4_set([name],value),
+# or assume that definition implies set membership.  Finally, size can
+# be tracked in an O(1) fashion with _m4_set_size(name).
+#
+# The quoting in _m4_set([name],value) is chosen so that there is no
+# ambiguity with a set whose name contains a comma, and so that we can
+# supply the value via _m4_defn([_m4_set([name])]) without needing any
+# quote manipulation.

+
+=head1 DESCRIPTION
+
+This packages defines channels that can be used in Automake to
+output diagnostics and other messages (via C<msg()>).  It also defines
+some helper function to enable or disable these channels, and some
+shorthand function to output on specific channels.

+=head1 DESCRIPTION
+
+This perl module provides support functions for handling diagnostic
+channels in programs.  Channels can be registered to convey fatal,
+error, warning, or debug messages.  Each channel has various options
+(e.g. is the channel silent, should duplicate messages be removed,
+etc.) that can also be overridden on a per-message basis.

+If C<UP_LOC_TEXT> is used, the location and the explanation message
+are used for filtering.  If C<UP_TEXT> is used, only the explanation
+message is used (so the same message will be filtered out if it appears

+=head2 Options
+
+Channels accept the options described below.  These options can be
+passed as a hash to the C<register_channel>, C<setup_channel>, and C<msg>
+functions.  The possible keys, with their default value are:
+
+=over
+
+=item C<type =E<gt> 'warning'>
+
+The type of the channel.  One of C<'debug'>, C<'warning'>, C<'error'>, or
+C<'fatal'>.  Fatal messages abort the program when they are output.
+Error messages update the exit status.  Debug and warning messages are
+harmless, except that warnings are treated as errors if
+C<$warnings_are_errors> is set.
+
+=item C<exit_code =E<gt> 1>
+
+The value to update C<$exit_code> with when a fatal or error message
+is emitted.  C<$exit_code> is also updated for warnings output
+when C<$warnings_are_errors> is set.
+
+=item C<file =E<gt> \*STDERR>
+
+The file where the error should be output.
+
+=item C<silent =E<gt> 0>
+
+Whether the channel should be silent.  Use this do disable a
+category of warning, for instance.
+
+=item C<ordered =E<gt> 1>
+
+Whether, with multi-threaded execution, the message should be queued
+for ordered output.
+
+=item C<uniq_part =E<gt> UP_LOC_TEXT>
+
+The part of the message subject to duplicate filtering.  See the
+documentation for the C<UP_NONE>, C<UP_TEXT>, and C<UP_LOC_TEXT>
+constants above.
+
+C<uniq_part> can also be set to an arbitrary string that will be used
+instead of the message when considering duplicates.
+
+=item C<uniq_scope =E<gt> US_LOCAL>
+
+The scope of duplicate filtering.  See the documentation for the
+C<US_LOCAL>, and C<US_GLOBAL> constants above.
+
+=item C<header =E<gt> ''>
+
+A string to prepend to each message emitted through this channel.
+With partial messages, only the first part will have C<header>
+prepended.
+
+=item C<footer =E<gt> ''>
+
+A string to append to each message emitted through this channel.
+With partial messages, only the final part will have C<footer>
+appended.
+
+=item C<backtrace =E<gt> 0>
+
+Die with a stack backtrace after displaying the message.
+
+=item C<partial =E<gt> 0>
+
+When set, indicates a partial message that should
+be output along with the next message with C<partial> unset.
+Several partial messages can be stacked this way.
+
+Duplicate filtering will apply to the I<global> message resulting from
+all I<partial> messages, using the options from the last (non-partial)
+message.  Linking associated messages is the main reason to use this
+option.
+
+For instance the following messages
+
+  msg 'channel', 'foo:2', 'redefinition of A ...';
+  msg 'channel', 'foo:1', '... A previously defined here';
+  msg 'channel', 'foo:3', 'redefinition of A ...';
+  msg 'channel', 'foo:1', '... A previously defined here';
+
+will result in
+
+ foo:2: redefinition of A ...
+ foo:1: ... A previously defined here
+ foo:3: redefinition of A ...
+
+where the duplicate "I<... A previously defined here>" has been
+filtered out.
+
+Linking these messages using C<partial> as follows will prevent the
+fourth message to disappear.
+
+  msg 'channel', 'foo:2', 'redefinition of A ...', partial => 1;
+  msg 'channel', 'foo:1', '... A previously defined here';
+  msg 'channel', 'foo:3', 'redefinition of A ...', partial => 1;
+  msg 'channel', 'foo:1', '... A previously defined here';
+
+Note that because the stack of C<partial> messages is printed with the
+first non-C<partial> message, most options of C<partial> messages will
+be ignored.

+
+Emit a message on C<$channel>, overriding some options of the channel with
+those specified in C<%options>.  Obviously C<$channel> must have been
+registered with C<register_channel>.
+
+C<$message> is the text of the message, and C<$location> is a location
+associated to the message.
+
+For instance to complain about some unused variable C<mumble>
+declared at line 10 in F<foo.c>, one could do:
+
+  msg 'unused', 'foo.c:10', "unused variable 'mumble'";
+
+If channel C<unused> is not silent (and if this message is not a duplicate),
+the following would be output:
+
+  foo.c:10: unused variable 'mumble'
+
+C<$location> can also be an instance of C<Automake::Location>.  In this
+case, the stack of contexts will be displayed in addition.
+
+If C<$message> contains newline characters, C<$location> is prepended
+to each line.  For instance,
+
+  msg 'error', 'somewhere', "1st line\n2nd line";
+
+becomes
+
+  somewhere: 1st line
+  somewhere: 2nd line
+
+If C<$location> is an empty string, it is replaced by the name of the
+program.  Actually, if you don't use C<%options>, you can even
+elide the empty C<$location>.  Thus

+
+After C<buffer_messages(@types)> has been called, messages sent with

+=head1 DESCRIPTION
+
+A C<Condition> is a conjunction of conditionals (i.e., atomic conditions
+defined in F<configure.ac> by C<AM_CONDITIONAL>.  In Automake they
+are used to represent the conditions into which F<Makefile> variables and
+F<Makefile> rules are defined.
+
+If the variable C<VAR> is defined as
+
+  if COND1
+    if COND2
+      VAR = value
+    endif
+  endif
+
+then it will be associated a C<Condition> created with
+the following statement.
+
+  new Automake::Condition "COND1_TRUE", "COND2_TRUE";
+
+Remember that a C<Condition> is a I<conjunction> of conditionals, so
+the above C<Condition> means C<VAR> is defined when C<COND1>
+B<and> C<COND2> are true. There is no way to express disjunctions
+(i.e., I<or>s) with this class (but see L<DisjConditions>).
+
+Another point worth to mention is that each C<Condition> object is
+unique with respect to its conditionals.  Two C<Condition> objects
+created for the same set of conditionals will have the same address.
+This makes it easy to compare C<Condition>s: just compare the
+references.
+
+  my $c1 = new Automake::Condition "COND1_TRUE", "COND2_TRUE";
+  my $c2 = new Automake::Condition "COND1_TRUE", "COND2_TRUE";
+  $c1 == $c2;  # True!
+
+=head2 Methods
+
+=over 4
+
+=item C<$cond = new Automake::Condition [@conds]>
+
+Return a C<Condition> objects for the conjunctions of conditionals
+listed in C<@conds> as strings.
+
+An item in C<@conds> should be either C<"FALSE">, C<"TRUE">, or have
+the form C<"NAME_FALSE"> or C<"NAME_TRUE"> where C<NAME> can be
+anything (in practice C<NAME> should be the name of a conditional
+declared in F<configure.ac> with C<AM_CONDITIONAL>, but it's not
+C<Automake::Condition>'s responsibility to ensure this).
+
+An empty C<@conds> means C<"TRUE">.
+
+As explained previously, the reference (object) returned is unique
+with respect to C<@conds>.  For this purpose, duplicate elements are
+ignored, and C<@conds> is rewritten as C<("FALSE")> if it contains
+C<"FALSE"> or two contradictory conditionals (such as C<"NAME_FALSE">
+and C<"NAME_TRUE">.)
+
+Therefore the following two statements create the same object (they
+both create the C<"FALSE"> condition).
+
+  my $c3 = new Automake::Condition "COND1_TRUE", "COND1_FALSE";
+  my $c4 = new Automake::Condition "COND2_TRUE", "FALSE";
+  $c3 == $c4;   # True!
+  $c3 == FALSE; # True!

+
+=head1 DESCRIPTION
+
+A C<DisjConditions> is a disjunction of C<Condition>s.  In Automake
+they are used to represent the conditions into which Makefile
+variables and Makefile rules are defined.
+
+If the variable C<VAR> is defined as
+
+  if COND1
+    if COND2
+      VAR = value1
+    endif
+  endif
+  if !COND3
+    if COND4
+      VAR = value2
+    endif
+  endif
+
+then it will be associated a C<DisjConditions> created with
+the following statement.
+
+  new Automake::DisjConditions
+    (new Automake::Condition ("COND1_TRUE", "COND2_TRUE"),
+     new Automake::Condition ("COND3_FALSE", "COND4_TRUE"));
+
+As you can see, a C<DisjConditions> is made from a list of
+C<Condition>s.  Since C<DisjConditions> is a disjunction, and
+C<Condition> is a conjunction, the above can be read as
+follows.
+
+  (COND1 and COND2) or ((not COND3) and COND4)
+
+That's indeed the condition in which C<VAR> has a value.
+
+Like C<Condition> objects, a C<DisjConditions> object is unique
+with respect to its conditions.  Two C<DisjConditions> objects created
+for the same set of conditions will have the same address.  This makes
+it easy to compare C<DisjConditions>s: just compare the references.
+
+=head2 Methods

+=head1 DESCRIPTION
+
+C<Location> objects are used to keep track of locations in Automake,
+and used to produce diagnostics.
+
+A C<Location> object is made of two parts: a location string, and
+a stack of contexts.
+
+For instance if C<VAR> is defined at line 1 in F<bar.h> which was
+included at line 14 in F<foo.c>, then the location string should be
+C<"bar.h:10"> and the context should be the pair (C<"foo.c:14">,
+C<"included from here">).
+
+Section I<SYNOPSIS> shows how to setup such a C<Location>, and access
+the location string or the stack of contexts.
+
+You can pass a C<Location> to C<Automake::Channels::msg>.

+
+Automake::Rule - support for rules definitions
+
+=head1 SYNOPSIS
+
+  use Automake::Rule;
+  use Automake::RuleDef;
+
+
+=head1 DESCRIPTION
+
+This package provides support for Makefile rule definitions.
+
+An C<Automake::Rule> is a rule name associated to possibly
+many conditional definitions.  These definitions are instances
+of C<Automake::RuleDef>.
+
+Therefore obtaining the value of a rule under a given
+condition involves two lookups.  One to look up the rule,
+and one to look up the conditional definition:
+
+  my $rule = rule $name;
+  if ($rule)
+    {
+      my $def = $rule->def ($cond);
+      if ($def)
+	{
+	  return $def->location;
+	}
+      ...
+    }
+  ...
+
+when it is known that the rule and the definition
+being looked up exist, the above can be simplified to
+
+  return rule ($name)->def ($cond)->location; # do not write this.
+
+but is better written
+
+  return rrule ($name)->rdef ($cond)->location;
+
+or even
+
+  return rruledef ($name, $cond)->location;
+
+The I<r> variants of the C<rule>, C<def>, and C<ruledef> methods add
+an extra test to ensure that the lookup succeeded, and will diagnose
+failures as internal errors (with a message which is much more
+informative than Perl's warning about calling a method on a
+non-object).

+
+Create a new Makefile-variable definition.  C<$varname> is the name of
+the variable being defined and C<$value> its value.
+
+C<$comment> is any comment preceding the definition.  (Because
+Automake reorders variable definitions in the output, it also tries to
+carry comments around.)
+
+C<$location> is the place where the definition occurred, it should be
+an instance of L<Automake::Location>.
+
+C<$type> should be C<''> for definitions made with C<=>, and C<':'>
+for those made with C<:=>.
+
+C<$owner> specifies who owns the variables, it can be one of
+C<VAR_AUTOMAKE>, C<VAR_CONFIGURE>, or C<VAR_MAKEFILE> (see these
+definitions).
+
+Finally, C<$pretty> tells how the variable should be output, and can
+be one of C<VAR_ASIS>, C<VAR_PRETTY>, or C<VAR_SILENT>, or
+C<VAR_SORTED> (see these definitions).

+
+
+=head1 DESCRIPTION
+
+This package provides support for Makefile variable definitions.
+
+An C<Automake::Variable> is a variable name associated to possibly
+many conditional definitions.  These definitions are instances
+of C<Automake::VarDef>.
+
+Therefore obtaining the value of a variable under a given
+condition involves two lookups.  One to look up the variable,
+and one to look up the conditional definition:
+
+  my $var = var $name;
+  if ($var)
+    {
+      my $def = $var->def ($cond);
+      if ($def)
+        {
+          return $def->value;
+        }
+      ...
+    }
+  ...
+
+When it is known that the variable and the definition
+being looked up exist, the above can be simplified to
+
+  return var ($name)->def ($cond)->value; # Do not write this.
+
+but is better written
+
+  return rvar ($name)->rdef ($cond)->value;
+
+or even
+
+  return rvardef ($name, $cond)->value;
+
+The I<r> variants of the C<var>, C<def>, and C<vardef> methods add an
+extra test to ensure that the lookup succeeded, and will diagnose
+failures as internal errors (with a message which is much more
+informative than Perl's warning about calling a method on a
+non-object).

+
+Split the value of the Automake::Variable C<$var> on space, and
+traverse its components recursively.
+
+If C<$cond_filter> is an C<Automake::Condition>, process any
+conditions which are true when C<$cond_filter> is true.  Otherwise,
+process all conditions.
+
+We distinguish two kinds of items in the content of C<$var>.
+Terms that look like C<$(foo)> or C<${foo}> are subvariables
+and cause recursion.  Other terms are assumed to be filenames.
+
+Each time a filename is encountered, C<&fun_item> is called with the
+following arguments:
+
+  ($var,        -- the Automake::Variable we are currently
+                   traversing
+   $val,        -- the item (i.e., filename) to process
+   $cond,       -- the Condition for the $var definition we are
+                   examining (ignoring the recursion context)
+   $full_cond)  -- the full Condition, taking into account
+                   conditions inherited from parent variables
+                   during recursion
+
+If C<inner_expand> is set, variable references occurring in filename
+(as in C<$(BASE).ext>) are expanded before the filename is passed to
+C<&fun_item>.
+
+If C<skip_ac_subst> is set, Autoconf @substitutions@ will be skipped,
+i.e., C<&fun_item> will never be called for them.
+
+C<&fun_item> may return a list of items, they will be passed to
+C<&fun_store> later on.  Define C<&fun_item> or @<&fun_store> as
+C<undef> when they serve no purpose.
+
+Once all items of a variable have been processed, the result (of the
+calls to C<&fun_items>, or of recursive traversals of subvariables)
+are passed to C<&fun_collect>.  C<&fun_collect> receives three
+arguments:
+
+  ($var,         -- the variable being traversed
+   $parent_cond, -- the Condition inherited from parent
+                    variables during recursion
+   @condlist)    -- a list of [$cond, @results] pairs
+                    where each $cond appear only once, and @result
+                    are all the results for this condition.
+
+Typically you should do C<$cond->merge ($parent_cond)> to recompute
+the C<$full_cond> associated to C<@result>.  C<&fun_collect> may
+return a list of items, that will be used as the result of
+C<Automake::Variable::traverse_recursively> (the top-level, or its
+recursive calls).

+=head1 NAME
+
+Automake::Version - version comparison
+
+=head1 SYNOPSIS
+
+  use Automake::Version;
+
+  print "Version $version is older than required version $required\n"
+    if Automake::Version::check ($version, $required);
+
+=head1 DESCRIPTION
+
+This module provides support for comparing versions string
+as they are used in Automake.
+
+A version is a string that looks like
+C<MAJOR.MINOR[.MICRO][ALPHA][-FORK]> where C<MAJOR>, C<MINOR>, and
+C<MICRO> are digits, C<ALPHA> is a character, and C<FORK> any
+alphanumeric word.
+
+Usually, C<ALPHA> is used to label alpha releases or intermediate
+snapshots, C<FORK> is used for git branches or patched releases, and
+C<MICRO> is used for bug fixes releases on the C<MAJOR.MINOR> branch.
+
+For the purpose of ordering, C<1.4> is the same as C<1.4.0>, but
+C<1.4g> is the same as C<1.4.99g>.  The C<FORK> identifier is ignored
+in the ordering, except when it looks like C<-pMINOR[ALPHA]>: some
+versions were labeled like C<1.4-p3a>, this is the same as an alpha
+release labeled C<1.4.3a>.  Yes, it's horrible, but Automake did not
+support two-dot versions in the past.
+
+=head2 FUNCTIONS
+
+=over 4
+
+=item C<split ($version)>
+
+Split the string C<$version> into the corresponding C<(MAJOR, MINOR,
+MICRO, ALPHA, FORK)> tuple.  For instance C<'1.4g'> would be split
+into C<(1, 4, 99, 'g', '')>.  Return C<()> on error.

+  }
+  return ();
+}
+
+=item C<compare (\@LVERSION, \@RVERSION)>
+
+Compare two version tuples, as returned by C<split>.
+
+Return 1, 0, or -1, if C<LVERSION> is found to be respectively
+greater than, equal to, or less than C<RVERSION>.

+    return -1 if ($l[$i] lt $r[$i]);
+  }
+  return 0;
+}
+
+=item C<check($VERSION, $REQUIRED)>
+
+Handles the logic of requiring a version number in Automake.
+C<$VERSION> should be Automake's version, while C<$REQUIRED>
+is the version required by the user input.
+
+Return 0 if the required version is satisfied, 1 otherwise.

+
+  print makefile_wrap ("VARIABLE = ", "    ", @values);
+
+=head1 DESCRIPTION
+
+This modules provide facility to format list of strings.  It is
+comparable to Perl's L<Text::Wrap>, however we can't use L<Text::Wrap>
+because some versions will abort when some word to print exceeds the
+maximum length allowed.  (Ticket #17141, fixed in Perl 5.8.0.)

+followed by the strings in C<@values> separated by spaces or by
+C<"$eol\n$fill"> so that the length of each line never exceeds
+C<$max_len>.

+The C<$max_len> constraint is ignored for C<@values> items which
+are too big to fit alone one a line.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the

+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of

+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the

+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,

+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>

+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see

+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with

+Installation Instructions

+without warranty of any kind.
+
+Basic Installation
+==================
+
+   Briefly, the shell command `./configure && make && make install'
+should configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.  Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the `make install' phase executed with root
+     privileges.
+
+  5. Optionally, type `make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior `make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type `make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide `make
+     distcheck', which can by used by developers to test that all other
+     targets like `make install' and `make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.  This
+is known as a "VPATH" build.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of `make' will be.  For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved.  Use GNU `make'
+instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf limitation.  Until the limitation is lifted, you can use
+this workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+## Yet another hack to support SUN make.
+##
+## Let's assume 'foo' appears in DISTFILES and is not a built file.
+## When building with VPATH=$(srcdir), SUN make and OSF1/Tru64 will
+## rewrite 'foo' as '$(srcdir)/foo'.  An attempt to install the file
+## with
+##    cp $file $(distdir)/$file
+## will thus install $(srcdir)/foo as $(distdir)/$(srcdir)/foo
+## instead of $(distdir)/foo.
+##
+## So let's strip this leading $(srcdir)/ when it exists.  (As far we
+## know, only SUN make and OSF1/Tru64 make add it.)  Searching whether
+## the file is to be found in the source or build directory will be
+## done later.
+##
+## In case we are _not_ using SUN or OSF1/Tru64 make, how can we be sure
+## we are not stripping a legitimate filename that starts with the
+## same pattern as $(srcdir)?
+## Well, it can't happen without the Makefile author distributing
+## something out of the distribution (which is bad).  As an example,
+## consider "EXTRA_DIST = ../bar".  This is an issue if $srcdir is
+## '..', however getting this value for srcdir is impossible:
+## "EXTRA_DIST = ../bar" implies we are in a subdirectory (so '../bar'
+## is within the package), hence '$srcdir' is something like
+## '../../subdir'.
+##
+## There is more to say about files which are above the current directory,
+## like '../bar' in the previous example.  The OSF1/Tru64 make
+## implementation can simplify filenames resulting from a VPATH lookup.
+## For instance if "VPATH = ../../subdir" and '../bar' is found in that
+## VPATH directory, then occurrences of '../bar' will be replaced by
+## '../../bar' (instead of '../../subdir/../bar').  This obviously defeats
+## any attempt to strip a leading $srcdir.  Presently we have no workaround
+## for this.  We avoid this issue by writing "EXTRA_DIST = $(srcdir)/../bar"
+## instead of "EXTRA_DIST = ../bar".  This prefixing is needed only for files
+## above the current directory.  Fortunately, apart from auxdir files which
+## can be located in .. or ../.., this situation hardly occurs in practice.
+##
+## Also rewrite $(top_srcdir) (which sometimes appears in DISTFILES, and can
+## be absolute) by $(top_builddir) (which is always relative).  $(srcdir) will

+## The -o option of GNU tar used to exclude empty directories.  This

+##
+## There are some tricky cases where this rule will build a
+## config.hin which has the same timestamp as %STAMP%, in which case
+## ./config.status will not be rerun (meaning that users will use an
+## out-of-date config.h without knowing it).  One situation where this
+## can occur is the following:
+## 1. the user updates some configure dependency (let's say foo.m4)
+##    and runs 'make';
+## 2. the rebuild rules detect that a foo.m4 has changed,
+##    run aclocal, autoconf, automake, and then run ./config.status.
+##    (Note that autoheader hasn't been called yet, so ./config.status
+##    outputs a config.h from an obsolete config.hin);
+## 3. once Makefile has been regenerated, make continues, and
+##    discovers that config.h is a dependency of the 'all' rule.
+##    Because config.h depends on stamp-h1, stamp-h1 depends on
+##    config.hin, and config.hin depends on aclocal.m4, make runs
+##    autoheader to rebuild config.hin.
+## Now make ought to call ./config.status once again to rebuild
+## config.h from the new config.hin, but if you have a sufficiently
+## fast box, steps 2 and 3 will occur within the same second: the
+## config.h/stamp-h1 generated from the outdated config.hin will have
+## the same mtime as the new config.hin.  Hence make will think that
+## config.h is up to date.
+##
+## A solution is to erase %STAMP% here so that the %STAMP% rule
+## is always triggered after the this one.
+	rm -f %STAMP%
+## Autoheader has the bad habit of not changing the timestamp if
+## config.hin is unchanged, which breaks Make targets.  Since what

+## config.hin.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH

+% Please try the latest version of texinfo.tex before submitting bug

+%   http://ftpmirror.gnu.org/texinfo/ (same, via a mirror), or

+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+**********
+
+1994-09-19 First CVS commit.
+
+     If we can trust the CVS repository, David J. MacKenzie (djm)
+     started working on Automake (or AutoMake, as it was spelt then)
+     this Monday.
+
+     The first version of the 'automake' script looks as follows.
+
+          #!/bin/sh
+
+          status=0
+
+          for makefile
+          do
+            if test ! -f ${makefile}.am; then
+              echo "automake: ${makefile}.am: No such honkin' file"
+              status=1
+              continue
+            fi
+
+            exec 4> ${makefile}.in
+
+          done
+
+     From this you can already see that Automake will be about reading
+     '*.am' file and producing '*.in' files.  You cannot see anything
+     else, but if you also know that David is the one who created
+     Autoconf two years before you can guess the rest.
+
+     Several commits follow, and by the end of the day Automake is
+     reported to work for GNU fileutils and GNU m4.
+
+     The modus operandi is the one that is still used today: variable
+     assignments in 'Makefile.am' files trigger injections of precanned
+     'Makefile' fragments into the generated 'Makefile.in'.  The use of
+     'Makefile' fragments was inspired by the 4.4BSD 'make' and include
+     files, however Automake aims to be portable and to conform to the
+     GNU standards for 'Makefile' variables and targets.
+
+     At this point, the most recent release of Autoconf is version 1.11,
+     and David is preparing to release Autoconf 2.0 in late October.  As
+     a matter of fact, he will barely touch Automake after September.
+
+1994-11-05 David MacKenzie's last commit.
+
+     At this point Automake is a 200 line portable shell script, plus
+     332 lines of 'Makefile' fragments.  In the 'README', David states
+     his ambivalence between "portable shell" and "more appropriate
+     language":
+
+          I wrote it keeping in mind the possibility of it becoming an
+          Autoconf macro, so it would run at configure-time.  That would
+          slow configuration down a bit, but allow users to modify the
+          Makefile.am without needing to fetch the AutoMake package.
+          And, the Makefile.in files wouldn't need to be distributed.
+          But all of AutoMake would.  So I might reimplement AutoMake in
+          Perl, m4, or some other more appropriate language.
+
+     Automake is described as "an experimental Makefile generator".
+     There is no documentation.  Adventurous users are referred to the
+     examples and patches needed to use Automake with GNU m4 1.3,
+     fileutils 3.9, time 1.6, and development versions of find and
+     indent.
+
+     These examples seem to have been lost.  However at the time of
+     writing (10 years later in September, 2004) the FSF still
+     distributes a package that uses this version of Automake: check out
+     GNU termutils 2.0.
+
+1995-11-12 Tom Tromey's first commit.
+
+     After one year of inactivity, Tom Tromey takes over the package.
+     Tom was working on GNU cpio back then, and doing this just for fun,
+     having trouble finding a project to contribute to.  So while
+     hacking he wanted to bring the 'Makefile.in' up to GNU standards.
+     This was hard, and one day he saw Automake on
+     <ftp://alpha.gnu.org/>, grabbed it and tried it out.
+
+     Tom didn't talk to djm about it until later, just to make sure he
+     didn't mind if he made a release.  He did a bunch of early releases
+     to the Gnits folks.
+
+     Gnits was (and still is) totally informal, just a few GNU friends
+     who Franc,ois Pinard knew, who were all interested in making a
+     common infrastructure for GNU projects, and shared a similar
+     outlook on how to do it.  So they were able to make some progress.
+     It came along with Autoconf and extensions thereof, and then
+     Automake from David and Tom (who were both gnitsians).  One of
+     their ideas was to write a document paralleling the GNU standards,
+     that was more strict in some ways and more detailed.  They never
+     finished the GNITS standards, but the ideas mostly made their way
+     into Automake.
+
+1995-11-23 Automake 0.20
+
+     Besides introducing automatic dependency tracking (*note Dependency
+     Tracking Evolution::), this version also supplies a 9-page manual.
+
+     At this time 'aclocal' and 'AM_INIT_AUTOMAKE' did not exist, so
+     many things had to be done by hand.  For instance, here is what a
+     configure.in (this is the former name of the 'configure.ac' we use
+     today) must contain in order to use Automake 0.20:
+
+          PACKAGE=cpio
+          VERSION=2.3.911
+          AC_DEFINE_UNQUOTED(PACKAGE, "$PACKAGE")
+          AC_DEFINE_UNQUOTED(VERSION, "$VERSION")
+          AC_SUBST(PACKAGE)
+          AC_SUBST(VERSION)
+          AC_ARG_PROGRAM
+          AC_PROG_INSTALL
+
+     (Today all of the above is achieved by 'AC_INIT' and
+     'AM_INIT_AUTOMAKE'.)
+
+     Here is how programs are specified in 'Makefile.am':
+
+          PROGRAMS = hello
+          hello_SOURCES = hello.c
+
+     This looks pretty much like what we do today, except the 'PROGRAMS'
+     variable has no directory prefix specifying where 'hello' should be
+     installed: all programs are installed in '$(bindir)'.
+     'LIBPROGRAMS' can be used to specify programs that must be built
+     but not installed (it is called 'noinst_PROGRAMS' nowadays).
+
+     Programs can be built conditionally using 'AC_SUBST'itutions:
+
+          PROGRAMS = @progs@
+          AM_PROGRAMS = foo bar baz
+
+     ('AM_PROGRAMS' has since then been renamed to 'EXTRA_PROGRAMS'.)
+
+     Similarly scripts, static libraries, and data can be built and
+     installed using the 'LIBRARIES', 'SCRIPTS', and 'DATA' variables.
+     However 'LIBRARIES' were treated a bit specially in that Automake
+     did automatically supply the 'lib' and '.a' prefixes.  Therefore to
+     build 'libcpio.a', one had to write
+
+          LIBRARIES = cpio
+          cpio_SOURCES = ...
+
+     Extra files to distribute must be listed in 'DIST_OTHER' (the
+     ancestor of 'EXTRA_DIST').  Also extra directories that are to be
+     distributed should appear in 'DIST_SUBDIRS', but the manual
+     describes this as a temporary ugly hack (today extra directories
+     should also be listed in 'EXTRA_DIST', and 'DIST_SUBDIRS' is used
+     for another purpose, *note Conditional Subdirectories:
+     (automake)Conditional Subdirectories.).
+
+1995-11-26 Automake 0.21
+
+     In less time than it takes to cook a frozen pizza, Tom rewrites
+     Automake using Perl.  At this time Perl 5 is only one year old, and
+     Perl 4.036 is in use at many sites.  Supporting several Perl
+     versions has been a source of problems through the whole history of
+     Automake.
+
+     If you never used Perl 4, imagine Perl 5 without objects, without
+     'my' variables (only dynamically scoped 'local' variables), without
+     function prototypes, with function calls that needs to be prefixed
+     with '&', etc.  Traces of this old style can still be found in
+     today's 'automake'.
+
+1995-11-28 Automake 0.22
+1995-11-29 Automake 0.23
+
+     Bug fixes.

+1995-12-08 Automake 0.24
+1995-12-10 Automake 0.25
+
+     Releases are raining.  0.24 introduces the uniform naming scheme we
+     use today, i.e., 'bin_PROGRAMS' instead of 'PROGRAMS',
+     'noinst_LIBRARIES' instead of 'LIBLIBRARIES', etc.  (However
+     'EXTRA_PROGRAMS' does not exist yet, 'AM_PROGRAMS' is still in use;
+     and 'TEXINFOS' and 'MANS' still have no directory prefixes.)
+     Adding support for prefixes like that was one of the major ideas in
+     'automake'; it has lasted pretty well.
+
+     AutoMake is renamed to Automake (Tom seems to recall it was
+     Franc,ois Pinard's doing).
+
+     0.25 fixes a Perl 4 portability bug.
+
+1995-12-18 Jim Meyering starts using Automake in GNU Textutils.
+1995-12-31 Franc,ois Pinard starts using Automake in GNU tar.
+
+1996-01-03 Automake 0.26
+1996-01-03 Automake 0.27
+
+     Of the many changes and suggestions sent by Franc,ois Pinard and
+     included in 0.26, perhaps the most important is the advice that to
+     ease customization a user rule or variable definition should always
+     override an Automake rule or definition.
+
+     Gordon Matzigkeit and Jim Meyering are two other early contributors
+     that have been sending fixes.
+
+     0.27 fixes yet another Perl 4 portability bug.
+
+1996-01-13 Automake 0.28
+
+     Automake starts scanning 'configure.in' for 'LIBOBJS' support.
+     This is an important step because until this version Automake only
+     knew about the 'Makefile.am's it processed.  'configure.in' was
+     Autoconf's world and the link between Autoconf and Automake had to
+     be done by the 'Makefile.am' author.  For instance, if 'config.h'
+     was generated by 'configure', it was the package maintainer's
+     responsibility to define the 'CONFIG_HEADER' variable in each
+     'Makefile.am'.
+
+     Succeeding releases will rely more and more on scanning
+     'configure.in' to better automate the Autoconf integration.
+
+     0.28 also introduces the 'AUTOMAKE_OPTIONS' variable and the
+     '--gnu' and '--gnits' options, the latter being stricter.
+
+1996-02-07 Automake 0.29
+
+     Thanks to 'configure.in' scanning, 'CONFIG_HEADER' is gone, and
+     rebuild rules for 'configure'-generated file are automatically
+     output.
+
+     'TEXINFOS' and 'MANS' converted to the uniform naming scheme.
+
+1996-02-24 Automake 0.30
+
+     The test suite is born.  It contains 9 tests.  From now on test
+     cases will be added pretty regularly (*note Releases::), and this
+     proved to be really helpful later on.
+
+     'EXTRA_PROGRAMS' finally replaces 'AM_PROGRAMS'.
+
+     All the third-party Autoconf macros, written mostly by Franc,ois
+     Pinard (and later Jim Meyering), are distributed in Automake's
+     hand-written 'aclocal.m4' file.  Package maintainers are expected
+     to extract the necessary macros from this file.  (In previous
+     versions you had to copy and paste them from the manual...)
+
+1996-03-11 Automake 0.31
+
+     The test suite in 0.30 was run via a long 'check-local' rule.  Upon
+     Ulrich Drepper's suggestion, 0.31 makes it an Automake rule output
+     whenever the 'TESTS' variable is defined.
+
+     'DIST_OTHER' is renamed to 'EXTRA_DIST', and the 'check_' prefix is
+     introduced.  The syntax is now the same as today.
+
+1996-03-15 Gordon Matzigkeit starts writing libtool.
+
+1996-04-27 Automake 0.32
+
+     '-hook' targets are introduced; an idea from Dieter Baron.
+
+     '*.info' files, which were output in the build directory are now
+     built in the source directory, because they are distributed.  It
+     seems these files like to move back and forth as that will happen
+     again in future versions.
+
+1996-05-18 Automake 0.33
+
+     Gord Matzigkeit's main two contributions:
+
+        * very preliminary libtool support
+        * the distcheck rule
+
+     Although they were very basic at this point, these are probably
+     among the top features for Automake today.
+
+     Jim Meyering also provides the infamous 'jm_MAINTAINER_MODE', since
+     then renamed to 'AM_MAINTAINER_MODE' and abandoned by its author
+     (*note maintainer-mode: (automake)maintainer-mode.).
+
+1996-05-28 Automake 1.0
+
+     After only six months of heavy development, the 'automake' script
+     is 3134 lines long, plus 973 lines of 'Makefile' fragments.  The
+     package has 30 pages of documentation, and 38 test cases.
+     'aclocal.m4' contains 4 macros.
+
+     From now on and until version 1.4, new releases will occur at a
+     rate of about one a year.  1.1 did not exist, actually 1.1b to 1.1p
+     have been the name of beta releases for 1.2.  This is the first
+     time Automake uses suffix letters to designate beta releases, a
+     habit that lasts.
+
+1996-10-10 Kevin Dalley packages Automake 1.0 for Debian GNU/Linux.
+
+1996-11-26 David J. MacKenzie releases Autoconf 2.12.
+
+     Between June and October, the Autoconf development is almost
+     stalled.  Roland McGrath has been working at the beginning of the
+     year.  David comes back in November to release 2.12, but he won't
+     touch Autoconf anymore after this year, and Autoconf then really
+     stagnates.  The desolate Autoconf 'ChangeLog' for 1997 lists only 7
+     commits.
+
+1997-02-28 <automake@gnu.ai.mit.edu> list alive
+
+     The mailing list is announced as follows:
+          I've created the "automake" mailing list.  It is
+          "automake@gnu.ai.mit.edu".  Administrivia, as always, to
+          automake-request@gnu.ai.mit.edu.
+
+          The charter of this list is discussion of automake, autoconf, and
+          other configuration/portability tools (e.g., libtool).  It is expected
+          that discussion will range from pleas for help all the way up to
+          patches.
+
+          This list is archived on the FSF machines.  Offhand I don't know if
+          you can get the archive without an account there.
+
+          This list is open to anybody who wants to join.  Tell all your
+          friends!
+          -- Tom Tromey
+
+     Before that people were discussing Automake privately, on the Gnits
+     mailing list (which is not public either), and less frequently on
+     'gnu.misc.discuss'.
+
+     'gnu.ai.mit.edu' is now 'gnu.org', in case you never noticed.  The
+     archives of the early years of the 'automake@gnu.org' list have
+     been lost, so today it is almost impossible to find traces of
+     discussions that occurred before 1999.  This has been annoying more
+     than once, as such discussions can be useful to understand the
+     rationale behind a piece of uncommented code that was introduced
+     back then.
+
+1997-06-22 Automake 1.2
+
+     Automake developments continues, and more and more new Autoconf
+     macros are required.  Distributing them in 'aclocal.m4' and
+     requiring people to browse this file to extract the relevant macros
+     becomes uncomfortable.  Ideally, some of them should be contributed
+     to Autoconf so that they can be used directly, however Autoconf is
+     currently inactive.  Automake 1.2 consequently introduces 'aclocal'
+     ('aclocal' was actually started on 1996-07-28), a tool that
+     automatically constructs an 'aclocal.m4' file from a repository of
+     third-party macros.  Because Autoconf has stalled, Automake also
+     becomes a kind of repository for such third-party macros, even
+     macros completely unrelated to Automake (for instance macros that
+     fix broken Autoconf macros).
+
+     The 1.2 release contains 20 macros, including the
+     'AM_INIT_AUTOMAKE' macro that simplifies the creation of
+     'configure.in'.
+
+     Libtool is fully supported using '*_LTLIBRARIES'.
+
+     The missing script is introduced by Franc,ois Pinard; it is meant
+     to be a better solution than 'AM_MAINTAINER_MODE' (*note
+     maintainer-mode: (automake)maintainer-mode.).
+
+     Conditionals support was implemented by Ian Lance Taylor.  At the
+     time, Tom and Ian were working on an internal project at Cygnus.
+     They were using ILU, which is pretty similar to CORBA.  They wanted
+     to integrate ILU into their build, which was all 'configure'-based,
+     and Ian thought that adding conditionals to 'automake' was simpler
+     than doing all the work in 'configure' (which was the standard at
+     the time).  So this was actually funded by Cygnus.
+
+     This very useful but tricky feature will take a lot of time to
+     stabilize.  (At the time this text is written, there are still
+     primaries that have not been updated to support conditional
+     definitions in Automake 1.9.)
+
+     The 'automake' script has almost doubled: 6089 lines of Perl, plus
+     1294 lines of 'Makefile' fragments.
+
+1997-07-08 Gordon Matzigkeit releases Libtool 1.0.
+
+1998-04-05 Automake 1.3
+
+     This is a small advance compared to 1.2.  It adds support for
+     assembly, and preliminary support for Java.
+
+     Perl 5.004_04 is out, but fixes to support Perl 4 are still
+     regularly submitted whenever Automake breaks it.
+
+1998-09-06 'sourceware.cygnus.com' is on-line.
+
+     Sourceware was setup by Jason Molenda to host open source projects.
+
+1998-09-19 Automake CVS repository moved to 'sourceware.cygnus.com'
+1998-10-26 'sourceware.cygnus.com' announces it hosts Automake:
+     Automake is now hosted on 'sourceware.cygnus.com'.  It has a
+     publicly accessible CVS repository.  This CVS repository is a copy
+     of the one Tom was using on his machine, which in turn is based on
+     a copy of the CVS repository of David MacKenzie.  This is why we
+     still have to full source history.  (Automake was on Sourceware
+     until 2007-10-29, when it moved to a git repository on
+     'savannah.gnu.org', but the Sourceware host had been renamed to
+     'sources.redhat.com'.)
+
+     The oldest file in the administrative directory of the CVS
+     repository that was created on Sourceware is dated 1998-09-19,
+     while the announcement that 'automake' and 'autoconf' had joined
+     'sourceware' was made on 1998-10-26.  They were among the first
+     projects to be hosted there.
+
+     The heedful reader will have noticed Automake was exactly 4 years
+     old on 1998-09-19.
+
+1999-01-05 Ben Elliston releases Autoconf 2.13.
+
+1999-01-14 Automake 1.4
+
+     This release adds support for Fortran 77 and for the 'include'
+     statement.  Also, '+=' assignments are introduced, but it is still
+     quite easy to fool Automake when mixing this with conditionals.
+
+     These two releases, Automake 1.4 and Autoconf 2.13 make a duo that
+     will be used together for years.
+
+     'automake' is 7228 lines, plus 1591 lines of Makefile fragment, 20
+     macros (some 1.3 macros were finally contributed back to Autoconf),
+     197 test cases, and 51 pages of documentation.
+
+1999-03-27 The 'user-dep-branch' is created on the CVS repository.
+
+     This implements a new dependency tracking schemed that should be
+     able to handle automatic dependency tracking using any compiler
+     (not just gcc) and any make (not just GNU 'make').  In addition,
+     the new scheme should be more reliable than the old one, as
+     dependencies are generated on the end user's machine.  Alexandre
+     Oliva creates depcomp for this purpose.
+
+     *Note Dependency Tracking Evolution::, for more details about the
+     evolution of automatic dependency tracking in Automake.
+
+1999-11-21 The 'user-dep-branch' is merged into the main trunk.
+
+     This was a huge problem since we also had patches going in on the
+     trunk.  The merge took a long time and was very painful.
+
+2000-05-10
+
+     Since September 1999 and until 2003, Akim Demaille will be
+     zealously revamping Autoconf.
+
+          I think the next release should be called "3.0".
+          Let's face it: you've basically rewritten autoconf.
+          Every weekend there are 30 new patches.
+          I don't see how we could call this "2.15" with a straight
+          face.
+          - Tom Tromey on <autoconf@gnu.org>
+
+     Actually Akim works like a submarine: he will pile up patches while
+     he works off-line during the weekend, and flush them in batch when
+     he resurfaces on Monday.
+
+2001-01-24
+
+     On this Wednesday, Autoconf 2.49c, the last beta before Autoconf
+     2.50 is out, and Akim has to find something to do during his
+     week-end :)
+
+2001-01-28
+
+     Akim sends a batch of 14 patches to <automake@gnu.org>.
+
+          Aiieeee!  I was dreading the day that the Demaillator turned
+          his sights on automake... and now it has arrived!  - Tom
+          Tromey
+
+     It's only the beginning: in two months he will send 192 patches.
+     Then he would slow down so Tom can catch up and review all this.
+     Initially Tom actually read all of these patches, then he probably
+     trustingly answered OK to most of them, and finally gave up and let
+     Akim apply whatever he wanted.  There was no way to keep up with
+     that patch rate.
+
+          Anyway the patch below won't apply since it predates Akim's
+          sourcequake; I have yet to figure where the relevant passage
+          has been moved :) - Alexandre Duret-Lutz
+
+     All of these patches were sent to and discussed on
+     <automake@gnu.org>, so subscribed users were literally drowning in
+     technical mails.  Eventually, the <automake-patches@gnu.org>
+     mailing list was created in May.
+
+     Year after year, Automake had drifted away from its initial design:
+     construct 'Makefile.in' by assembling various 'Makefile' fragments.
+     In 1.4, lots of 'Makefile' rules are being emitted at various
+     places in the 'automake' script itself; this does not help ensuring
+     a consistent treatment of these rules (for instance making sure
+     that user-defined rules override Automake's own rules).  One of
+     Akim's goal was moving all of these hard-coded rules to separate
+     'Makefile' fragments, so the logic could be centralized in a
+     'Makefile' fragment processor.
+
+     Another significant contribution of Akim is the interface with the
+     "trace" feature of Autoconf.  The way to scan 'configure.in' at
+     this time was to read the file and grep the various macro of
+     interest to Automake.  Doing so could break in many unexpected
+     ways; 'automake' could miss some definition (for instance
+     'AC_SUBST([$1], [$2])' where the arguments are known only when M4
+     is run), or conversely it could detect some macro that was not
+     expanded (because it is called conditionally).  In the CVS version
+     of Autoconf, Akim had implemented the '--trace' option, which
+     provides accurate information about where macros are actually
+     called and with what arguments.  Akim will equip Automake with a
+     second 'configure.in' scanner that uses this '--trace' interface.
+     Since it was not sensible to drop the Autoconf 2.13 compatibility
+     yet, this experimental scanner was only used when an environment
+     variable was set, the traditional grep-scanner being still the
+     default.
+
+2001-04-25 Gary V. Vaughan releases Libtool 1.4
+
+     It has been more than two years since Automake 1.4, CVS Automake
+     has suffered lot's of heavy changes and still is not ready for
+     release.  Libtool 1.4 had to be distributed with a patch against
+     Automake 1.4.
+
+2001-05-08 Automake 1.4-p1
+2001-05-24 Automake 1.4-p2
+
+     Gary V. Vaughan, the principal Libtool maintainer, makes a "patch
+     release" of Automake:
+
+          The main purpose of this release is to have a stable automake
+          which is compatible with the latest stable libtool.
+
+     The release also contains obvious fixes for bugs in Automake 1.4,
+     some of which were reported almost monthly.
+
+2001-05-21 Akim Demaille releases Autoconf 2.50
+
+2001-06-07 Automake 1.4-p3
+2001-06-10 Automake 1.4-p4
+2001-07-15 Automake 1.4-p5
+
+     Gary continues his patch-release series.  These also add support
+     for some new Autoconf 2.50 idioms.  Essentially, Autoconf now
+     advocates 'configure.ac' over 'configure.in', and it introduces a
+     new syntax for 'AC_OUTPUT'ing files.
+
+2001-08-23 Automake 1.5
+
+     A major and long-awaited release, that comes more than two years
+     after 1.4.  It brings many changes, among which:
+        * The new dependency tracking scheme that uses 'depcomp'.  Aside
+          from the improvement on the dependency tracking itself (*note
+          Dependency Tracking Evolution::), this also streamlines the
+          use of 'automake'-generated 'Makefile.in's as the
+          'Makefile.in's used during development are now the same as
+          those used in distributions.  Before that the 'Makefile.in's
+          generated for maintainers required GNU 'make' and GCC, they
+          were different from the portable 'Makefile' generated for
+          distribution; this was causing some confusion.
+
+        * Support for per-target compilation flags.
+
+        * Support for reference to files in subdirectories in most
+          'Makefile.am' variables.
+
+        * Introduction of the 'dist_', 'nodist_', and 'nobase_'
+          prefixes.
+        * Perl 4 support is finally dropped.
+
+     1.5 did break several packages that worked with 1.4.  Enough so
+     that Linux distributions could not easily install the new Automake
+     version without breaking many of the packages for which they had to
+     run 'automake'.
+
+     Some of these breakages were effectively bugs that would eventually
+     be fixed in the next release.  However, a lot of damage was caused
+     by some changes made deliberately to render Automake stricter on
+     some setup we did consider bogus.  For instance, 'make distcheck'
+     was improved to check that 'make uninstall' did remove all the
+     files 'make install' installed, that 'make distclean' did not omit
+     some file, and that a VPATH build would work even if the source
+     directory was read-only.  Similarly, Automake now rejects multiple
+     definitions of the same variable (because that would mix very badly
+     with conditionals), and '+=' assignments with no previous
+     definition.  Because these changes all occurred suddenly after 1.4
+     had been established for more than two years, it hurt users.
+
+     To make matter worse, meanwhile Autoconf (now at version 2.52) was
+     facing similar troubles, for similar reasons.
+
+2002-03-05 Automake 1.6
+
+     This release introduced versioned installation (*note API
+     Versioning: (automake)API Versioning.).  This was mainly pushed by
+     Havoc Pennington, taking the GNOME source tree as motive: due to
+     incompatibilities between the autotools it's impossible for the
+     GNOME packages to switch to Autoconf 2.53 and Automake 1.5 all at
+     once, so they are currently stuck with Autoconf 2.13 and Automake
+     1.4.
+
+     The idea was to call this version 'automake-1.6', call all its
+     bug-fix versions identically, and switch to 'automake-1.7' for the
+     next release that adds new features or changes some rules.  This
+     scheme implies maintaining a bug-fix branch in addition to the
+     development trunk, which means more work from the maintainer, but
+     providing regular bug-fix releases proved to be really worthwhile.
+
+     Like 1.5, 1.6 also introduced a bunch of incompatibilities,
+     intentional or not.  Perhaps the more annoying was the dependence
+     on the newly released Autoconf 2.53.  Autoconf seemed to have
+     stabilized enough since its explosive 2.50 release and included
+     changes required to fix some bugs in Automake.  In order to upgrade
+     to Automake 1.6, people now had to upgrade Autoconf too; for some
+     packages it was no picnic.
+
+     While versioned installation helped people to upgrade, it also
+     unfortunately allowed people not to upgrade.  At the time of
+     writing, some Linux distributions are shipping packages for
+     Automake 1.4, 1.5, 1.6, 1.7, 1.8, and 1.9.  Most of these still
+     install 1.4 by default.  Some distribution also call 1.4 the
+     "stable" version, and present "1.9" as the development version;
+     this does not really makes sense since 1.9 is way more solid than
+     1.4.  All this does not help the newcomer.
+
+2002-04-11 Automake 1.6.1
+
+     1.6, and the upcoming 1.4-p6 release were the last release by Tom.
+     This one and those following will be handled by Alexandre
+     Duret-Lutz.  Tom is still around, and will be there until about
+     1.7, but his interest into Automake is drifting away towards
+     projects like 'gcj'.
+
+     Alexandre has been using Automake since 2000, and started to
+     contribute mostly on Akim's incitement (Akim and Alexandre have
+     been working in the same room from 1999 to 2002).  In 2001 and 2002
+     he had a lot of free time to enjoy hacking Automake.
+
+2002-06-14 Automake 1.6.2
+
+2002-07-28 Automake 1.6.3
+2002-07-28 Automake 1.4-p6
+
+     Two releases on the same day.  1.6.3 is a bug-fix release.
+
+     Tom Tromey backported the versioned installation mechanism on the
+     1.4 branch, so that Automake 1.6.x and Automake 1.4-p6 could be
+     installed side by side.  Another request from the GNOME folks.
+
+2002-09-25 Automake 1.7
+
+     This release switches to the new 'configure.ac' scanner Akim was
+     experimenting in 1.5.
+

+
+     'aclocal' now uses 'm4_include' in the produced 'aclocal.m4' when

+     people liked that, but in fact this change was really introduced to
+     fix a bug in rebuild rules: 'Makefile.in' must be rebuilt whenever
+     a dependency of 'configure' changes, but all the 'm4' files
+     included in 'aclocal.m4' where unknown from 'automake'.  Now
+     'automake' can just trace the 'm4_include's to discover the
+     dependencies.
+
+     'aclocal' also starts using the '--trace' Autoconf option in order
+     to discover used macros more accurately.  This will turn out to be
+     very tricky (later releases will improve this) as people had
+     devised many ways to cope with the limitation of previous 'aclocal'
+     versions, notably using handwritten 'm4_include's: 'aclocal' must
+     make sure not to redefine a rule that is already included by such
+     statement.
+
+     Automake also has seen its guts rewritten.  Although this rewriting
+     took a lot of efforts, it is only apparent to the users in that

+
+2.1 First Take on Dependency Tracking
+=====================================
+
+Description
+-----------
+
+Our first attempt at automatic dependency tracking was based on the
+method recommended by GNU 'make'.  (*note Generating Prerequisites
+Automatically: (make)Automatic Prerequisites.)
+
+   This version worked by precomputing dependencies ahead of time.  For
+each source file, it had a special '.P' file that held the dependencies.
+There was a rule to generate a '.P' file by invoking the compiler
+appropriately.  All such '.P' files were included by the 'Makefile',
+thus implicitly becoming dependencies of 'Makefile'.
+
+Bugs
+----
+
+This approach had several critical bugs.
+
+   * The code to generate the '.P' file relied on 'gcc'.  (A limitation,
+     not technically a bug.)
+   * The dependency tracking mechanism itself relied on GNU 'make'.  (A
+     limitation, not technically a bug.)
+   * Because each '.P' file was a dependency of 'Makefile', this meant
+     that dependency tracking was done eagerly by 'make'.  For instance,
+     'make clean' would cause all the dependency files to be updated,
+     and then immediately removed.  This eagerness also caused problems
+     with some configurations; if a certain source file could not be
+     compiled on a given architecture for some reason, dependency
+     tracking would fail, aborting the entire build.
+   * As dependency tracking was done as a pre-pass, compile times were
+     doubled-the compiler had to be run twice per source file.
+   * 'make dist' re-ran 'automake' to generate a 'Makefile' that did not
+     have automatic dependency tracking (and that was thus portable to
+     any version of 'make').  In order to do this portably, Automake had
+     to scan the dependency files and remove any reference that was to a
+     source file not in the distribution.  This process was error-prone.
+     Also, if 'make dist' was run in an environment where some object
+     file had a dependency on a source file that was only conditionally
+     created, Automake would generate a 'Makefile' that referred to a
+     file that might not appear in the end user's build.  A special,
+     hacky mechanism was required to work around this.
+
+Historical Note
+---------------
+
+The code generated by Automake is often inspired by the 'Makefile' style
+of a particular author.  In the case of the first implementation of
+dependency tracking, I believe the impetus and inspiration was Jim
+Meyering.  (I could be mistaken.  If you know otherwise feel free to
+correct me.)

+
+2.2 Dependencies As Side Effects
+================================
+
+Description
+-----------
+
+The next refinement of Automake's automatic dependency tracking scheme
+was to implement dependencies as side effects of the compilation.  This
+was aimed at solving the most commonly reported problems with the first
+approach.  In particular we were most concerned with eliminating the
+weird rebuilding effect associated with make clean.
+
+   In this approach, the '.P' files were included using the '-include'
+command, which let us create these files lazily.  This avoided the 'make
+clean' problem.
+
+   We only computed dependencies when a file was actually compiled.
+This avoided the performance penalty associated with scanning each file
+twice.  It also let us avoid the other problems associated with the
+first, eager, implementation.  For instance, dependencies would never be
+generated for a source file that was not compilable on a given
+architecture (because it in fact would never be compiled).
+
+Bugs
+----
+
+   * This approach also relied on the existence of 'gcc' and GNU 'make'.
+     (A limitation, not technically a bug.)
+   * Dependency tracking was still done by the developer, so the
+     problems from the first implementation relating to massaging of
+     dependencies by 'make dist' were still in effect.
+   * This implementation suffered from the "deleted header file"
+     problem.  Suppose a lazily-created '.P' file includes a dependency
+     on a given header file, like this:
+
+          maude.o: maude.c something.h
+
+     Now suppose that you remove 'something.h' and update 'maude.c' so
+     that this include is no longer needed.  If you run 'make', you will
+     get an error because there is no way to create 'something.h'.
+
+     We fixed this problem in a later release by further massaging the
+     output of 'gcc' to include a dummy dependency for each header file.

+
+2.3 Dependencies for the User
+=============================
+
+Description
+-----------
+
+The bugs associated with 'make dist', over time, became a real problem.
+Packages using Automake were being built on a large number of platforms,
+and were becoming increasingly complex.  Broken dependencies were
+distributed in "portable" 'Makefile.in's, leading to user complaints.
+Also, the requirement for 'gcc' and GNU 'make' was a constant source of
+bug reports.  The next implementation of dependency tracking aimed to
+remove these problems.
+
+   We realized that the only truly reliable way to automatically track
+dependencies was to do it when the package itself was built.  This meant
+discovering a method portable to any version of make and any compiler.
+Also, we wanted to preserve what we saw as the best point of the second
+implementation: dependency computation as a side effect of compilation.
+
+   In the end we found that most modern make implementations support
+some form of include directive.  Also, we wrote a wrapper script that
+let us abstract away differences between dependency tracking methods for
+compilers.  For instance, some compilers cannot generate dependencies as
+a side effect of compilation.  In this case we simply have the script
+run the compiler twice.  Currently our wrapper script ('depcomp') knows
+about twelve different compilers (including a "compiler" that simply
+invokes 'makedepend' and then the real compiler, which is assumed to be
+a standard Unix-like C compiler with no way to do dependency tracking).
+
+Bugs
+----
+
+   * Running a wrapper script for each compilation slows down the build.
+   * Many users don't really care about precise dependencies.
+   * This implementation, like every other automatic dependency tracking
+     scheme in common use today (indeed, every one we've ever heard of),
+     suffers from the "duplicated new header" bug.
+
+     This bug occurs because dependency tracking tools, such as the
+     compiler, only generate dependencies on the successful opening of a
+     file, and not on every probe.
+
+     Suppose for instance that the compiler searches three directories
+     for a given header, and that the header is found in the third
+     directory.  If the programmer erroneously adds a header file with
+     the same name to the first directory, then a clean rebuild from
+     scratch could fail (suppose the new header file is buggy), whereas
+     an incremental rebuild will succeed.
+
+     What has happened here is that people have a misunderstanding of
+     what a dependency is.  Tool writers think a dependency encodes
+     information about which files were read by the compiler.  However,
+     a dependency must actually encode information about what the
+     compiler tried to do.
+
+     This problem is not serious in practice.  Programmers typically do
+     not use the same name for a header file twice in a given project.
+     (At least, not in C or C++.  This problem may be more troublesome
+     in Java.)  This problem is easy to fix, by modifying dependency
+     generators to record every probe, instead of every successful open.
+
+   * Since Automake generates dependencies as a side effect of
+     compilation, there is a bootstrapping problem when header files are
+     generated by running a program.  The problem is that, the first
+     time the build is done, there is no way by default to know that the
+     headers are required, so make might try to run a compilation for
+     which the headers have not yet been built.
+
+     This was also a problem in the previous dependency tracking
+     implementation.
+
+     The current fix is to use 'BUILT_SOURCES' to list built headers
+     (*note Sources: (automake)Sources.).  This causes them to be built
+     before any other build rules are run.  This is unsatisfactory as a
+     general solution, however in practice it seems sufficient for most
+     actual programs.
+
+   This code is used since Automake 1.5.
+
+   In GCC 3.0, we managed to convince the maintainers to add special
+command-line options to help Automake more efficiently do its job.  We
+hoped this would let us avoid the use of a wrapper script when
+Automake's automatic dependency tracking was used with 'gcc'.
+
+   Unfortunately, this code doesn't quite do what we want.  In
+particular, it removes the dependency file if the compilation fails;
+we'd prefer that it instead only touch the file in any way if the
+compilation succeeds.
+
+   Nevertheless, since Automake 1.7, when a recent 'gcc' is detected at
+'configure' time, we inline the dependency-generation code and do not
+use the 'depcomp' wrapper script.  This makes compilations faster for
+those using this compiler (probably our primary user base).  The
+counterpart is that because we have to encode two compilation rules in
+'Makefile' (with or without 'depcomp'), the produced 'Makefile's are
+larger.

+
+2.4 Techniques for Computing Dependencies
+=========================================
+
+There are actually several ways for a build tool like Automake to cause
+tools to generate dependencies.
+
+'makedepend'
+     This was a commonly-used method in the past.  The idea is to run a
+     special program over the source and have it generate dependency
+     information.  Traditional implementations of 'makedepend' are not
+     completely precise; ordinarily they were conservative and
+     discovered too many dependencies.
+The tool
+     An obvious way to generate dependencies is to simply write the tool
+     so that it can generate the information needed by the build tool.
+     This is also the most portable method.  Many compilers have an
+     option to generate dependencies.  Unfortunately, not all tools
+     provide such an option.
+The file system
+     It is possible to write a special file system that tracks opens,
+     reads, writes, etc, and then feed this information back to the
+     build tool.  'clearmake' does this.  This is a very powerful
+     technique, as it doesn't require cooperation from the tool.
+     Unfortunately it is also very difficult to implement and also not
+     practical in the general case.
+'LD_PRELOAD'
+     Rather than use the file system, one could write a special library
+     to intercept 'open' and other syscalls.  This technique is also
+     quite powerful, but unfortunately it is not portable enough for use
+     in 'automake'.

+
+2.4.1 Recommendations for Tool Writers
+--------------------------------------
+
+We think that every compilation tool ought to be able to generate
+dependencies as a side effect of compilation.  Furthermore, at least
+while 'make'-based tools are nearly universally in use (at least in the
+free software community), the tool itself should generate dummy
+dependencies for header files, to avoid the deleted header file bug.
+Finally, the tool should generate a dependency for each probe, instead
+of each successful file open, in order to avoid the duplicated new
+header bug.

+
+2.4.2 Future Directions for Dependencies
+----------------------------------------
+
+Currently, only languages and compilers understood by Automake can have
+dependency tracking enabled.  We would like to see if it is practical
+(and worthwhile) to let this support be extended by the user to
+languages unknown to Automake.

+A.1 GNU Free Documentation License
+==================================
+
+                     Version 1.3, 3 November 2008
+
+     Copyright (C) 2000-2013 Free Software Foundation, Inc.
+     <http://fsf.org/>
+
+     Everyone is permitted to copy and distribute verbatim copies
+     of this license document, but changing it is not allowed.
+
+  0. PREAMBLE
+
+     The purpose of this License is to make a manual, textbook, or other
+     functional and useful document "free" in the sense of freedom: to
+     assure everyone the effective freedom to copy and redistribute it,
+     with or without modifying it, either commercially or
+     noncommercially.  Secondarily, this License preserves for the
+     author and publisher a way to get credit for their work, while not
+     being considered responsible for modifications made by others.
+
+     This License is a kind of "copyleft", which means that derivative
+     works of the document must themselves be free in the same sense.
+     It complements the GNU General Public License, which is a copyleft
+     license designed for free software.
+
+     We have designed this License in order to use it for manuals for
+     free software, because free software needs free documentation: a
+     free program should come with manuals providing the same freedoms
+     that the software does.  But this License is not limited to
+     software manuals; it can be used for any textual work, regardless
+     of subject matter or whether it is published as a printed book.  We
+     recommend this License principally for works whose purpose is
+     instruction or reference.
+
+  1. APPLICABILITY AND DEFINITIONS
+
+     This License applies to any manual or other work, in any medium,
+     that contains a notice placed by the copyright holder saying it can
+     be distributed under the terms of this License.  Such a notice
+     grants a world-wide, royalty-free license, unlimited in duration,
+     to use that work under the conditions stated herein.  The
+     "Document", below, refers to any such manual or work.  Any member
+     of the public is a licensee, and is addressed as "you".  You accept
+     the license if you copy, modify or distribute the work in a way
+     requiring permission under copyright law.
+
+     A "Modified Version" of the Document means any work containing the
+     Document or a portion of it, either copied verbatim, or with
+     modifications and/or translated into another language.
+
+     A "Secondary Section" is a named appendix or a front-matter section
+     of the Document that deals exclusively with the relationship of the
+     publishers or authors of the Document to the Document's overall
+     subject (or to related matters) and contains nothing that could
+     fall directly within that overall subject.  (Thus, if the Document
+     is in part a textbook of mathematics, a Secondary Section may not
+     explain any mathematics.)  The relationship could be a matter of
+     historical connection with the subject or with related matters, or
+     of legal, commercial, philosophical, ethical or political position
+     regarding them.
+
+     The "Invariant Sections" are certain Secondary Sections whose
+     titles are designated, as being those of Invariant Sections, in the
+     notice that says that the Document is released under this License.
+     If a section does not fit the above definition of Secondary then it
+     is not allowed to be designated as Invariant.  The Document may
+     contain zero Invariant Sections.  If the Document does not identify
+     any Invariant Sections then there are none.
+
+     The "Cover Texts" are certain short passages of text that are
+     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+     that says that the Document is released under this License.  A
+     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+     be at most 25 words.
+
+     A "Transparent" copy of the Document means a machine-readable copy,
+     represented in a format whose specification is available to the
+     general public, that is suitable for revising the document
+     straightforwardly with generic text editors or (for images composed
+     of pixels) generic paint programs or (for drawings) some widely
+     available drawing editor, and that is suitable for input to text
+     formatters or for automatic translation to a variety of formats
+     suitable for input to text formatters.  A copy made in an otherwise
+     Transparent file format whose markup, or absence of markup, has
+     been arranged to thwart or discourage subsequent modification by
+     readers is not Transparent.  An image format is not Transparent if
+     used for any substantial amount of text.  A copy that is not
+     "Transparent" is called "Opaque".
+
+     Examples of suitable formats for Transparent copies include plain
+     ASCII without markup, Texinfo input format, LaTeX input format,
+     SGML or XML using a publicly available DTD, and standard-conforming
+     simple HTML, PostScript or PDF designed for human modification.
+     Examples of transparent image formats include PNG, XCF and JPG.
+     Opaque formats include proprietary formats that can be read and
+     edited only by proprietary word processors, SGML or XML for which
+     the DTD and/or processing tools are not generally available, and
+     the machine-generated HTML, PostScript or PDF produced by some word
+     processors for output purposes only.
+
+     The "Title Page" means, for a printed book, the title page itself,
+     plus such following pages as are needed to hold, legibly, the
+     material this License requires to appear in the title page.  For
+     works in formats which do not have any title page as such, "Title
+     Page" means the text near the most prominent appearance of the
+     work's title, preceding the beginning of the body of the text.
+
+     The "publisher" means any person or entity that distributes copies
+     of the Document to the public.
+
+     A section "Entitled XYZ" means a named subunit of the Document
+     whose title either is precisely XYZ or contains XYZ in parentheses
+     following text that translates XYZ in another language.  (Here XYZ
+     stands for a specific section name mentioned below, such as
+     "Acknowledgements", "Dedications", "Endorsements", or "History".)
+     To "Preserve the Title" of such a section when you modify the
+     Document means that it remains a section "Entitled XYZ" according
+     to this definition.
+
+     The Document may include Warranty Disclaimers next to the notice
+     which states that this License applies to the Document.  These
+     Warranty Disclaimers are considered to be included by reference in
+     this License, but only as regards disclaiming warranties: any other
+     implication that these Warranty Disclaimers may have is void and
+     has no effect on the meaning of this License.
+
+  2. VERBATIM COPYING
+
+     You may copy and distribute the Document in any medium, either
+     commercially or noncommercially, provided that this License, the
+     copyright notices, and the license notice saying this License
+     applies to the Document are reproduced in all copies, and that you
+     add no other conditions whatsoever to those of this License.  You
+     may not use technical measures to obstruct or control the reading
+     or further copying of the copies you make or distribute.  However,
+     you may accept compensation in exchange for copies.  If you
+     distribute a large enough number of copies you must also follow the
+     conditions in section 3.
+
+     You may also lend copies, under the same conditions stated above,
+     and you may publicly display copies.
+
+  3. COPYING IN QUANTITY
+
+     If you publish printed copies (or copies in media that commonly
+     have printed covers) of the Document, numbering more than 100, and
+     the Document's license notice requires Cover Texts, you must
+     enclose the copies in covers that carry, clearly and legibly, all
+     of these Cover Texts: Front-Cover Texts on the front cover, and
+     Back-Cover Texts on the back cover.  Both covers must also clearly
+     and legibly identify you as the publisher of these copies.  The
+     front cover must present the full title with all words of the title
+     equally prominent and visible.  You may add other material on the
+     covers in addition.  Copying with changes limited to the covers, as
+     long as they preserve the title of the Document and satisfy these
+     conditions, can be treated as verbatim copying in other respects.
+
+     If the required texts for either cover are too voluminous to fit
+     legibly, you should put the first ones listed (as many as fit
+     reasonably) on the actual cover, and continue the rest onto
+     adjacent pages.
+
+     If you publish or distribute Opaque copies of the Document
+     numbering more than 100, you must either include a machine-readable
+     Transparent copy along with each Opaque copy, or state in or with
+     each Opaque copy a computer-network location from which the general
+     network-using public has access to download using public-standard
+     network protocols a complete Transparent copy of the Document, free
+     of added material.  If you use the latter option, you must take
+     reasonably prudent steps, when you begin distribution of Opaque
+     copies in quantity, to ensure that this Transparent copy will
+     remain thus accessible at the stated location until at least one
+     year after the last time you distribute an Opaque copy (directly or
+     through your agents or retailers) of that edition to the public.
+
+     It is requested, but not required, that you contact the authors of
+     the Document well before redistributing any large number of copies,
+     to give them a chance to provide you with an updated version of the
+     Document.
+
+  4. MODIFICATIONS
+
+     You may copy and distribute a Modified Version of the Document
+     under the conditions of sections 2 and 3 above, provided that you
+     release the Modified Version under precisely this License, with the
+     Modified Version filling the role of the Document, thus licensing
+     distribution and modification of the Modified Version to whoever
+     possesses a copy of it.  In addition, you must do these things in
+     the Modified Version:
+
+       A. Use in the Title Page (and on the covers, if any) a title
+          distinct from that of the Document, and from those of previous
+          versions (which should, if there were any, be listed in the
+          History section of the Document).  You may use the same title
+          as a previous version if the original publisher of that
+          version gives permission.
+
+       B. List on the Title Page, as authors, one or more persons or
+          entities responsible for authorship of the modifications in
+          the Modified Version, together with at least five of the
+          principal authors of the Document (all of its principal
+          authors, if it has fewer than five), unless they release you
+          from this requirement.
+
+       C. State on the Title page the name of the publisher of the
+          Modified Version, as the publisher.
+
+       D. Preserve all the copyright notices of the Document.
+
+       E. Add an appropriate copyright notice for your modifications
+          adjacent to the other copyright notices.
+
+       F. Include, immediately after the copyright notices, a license
+          notice giving the public permission to use the Modified
+          Version under the terms of this License, in the form shown in
+          the Addendum below.
+
+       G. Preserve in that license notice the full lists of Invariant
+          Sections and required Cover Texts given in the Document's
+          license notice.
+
+       H. Include an unaltered copy of this License.
+
+       I. Preserve the section Entitled "History", Preserve its Title,
+          and add to it an item stating at least the title, year, new
+          authors, and publisher of the Modified Version as given on the
+          Title Page.  If there is no section Entitled "History" in the
+          Document, create one stating the title, year, authors, and
+          publisher of the Document as given on its Title Page, then add
+          an item describing the Modified Version as stated in the
+          previous sentence.
+
+       J. Preserve the network location, if any, given in the Document
+          for public access to a Transparent copy of the Document, and
+          likewise the network locations given in the Document for
+          previous versions it was based on.  These may be placed in the
+          "History" section.  You may omit a network location for a work
+          that was published at least four years before the Document
+          itself, or if the original publisher of the version it refers
+          to gives permission.
+
+       K. For any section Entitled "Acknowledgements" or "Dedications",
+          Preserve the Title of the section, and preserve in the section
+          all the substance and tone of each of the contributor
+          acknowledgements and/or dedications given therein.
+
+       L. Preserve all the Invariant Sections of the Document, unaltered
+          in their text and in their titles.  Section numbers or the
+          equivalent are not considered part of the section titles.
+
+       M. Delete any section Entitled "Endorsements".  Such a section
+          may not be included in the Modified Version.
+
+       N. Do not retitle any existing section to be Entitled
+          "Endorsements" or to conflict in title with any Invariant
+          Section.
+
+       O. Preserve any Warranty Disclaimers.
+
+     If the Modified Version includes new front-matter sections or
+     appendices that qualify as Secondary Sections and contain no
+     material copied from the Document, you may at your option designate
+     some or all of these sections as invariant.  To do this, add their
+     titles to the list of Invariant Sections in the Modified Version's
+     license notice.  These titles must be distinct from any other
+     section titles.
+
+     You may add a section Entitled "Endorsements", provided it contains
+     nothing but endorsements of your Modified Version by various
+     parties--for example, statements of peer review or that the text
+     has been approved by an organization as the authoritative
+     definition of a standard.
+
+     You may add a passage of up to five words as a Front-Cover Text,
+     and a passage of up to 25 words as a Back-Cover Text, to the end of
+     the list of Cover Texts in the Modified Version.  Only one passage
+     of Front-Cover Text and one of Back-Cover Text may be added by (or
+     through arrangements made by) any one entity.  If the Document
+     already includes a cover text for the same cover, previously added
+     by you or by arrangement made by the same entity you are acting on
+     behalf of, you may not add another; but you may replace the old
+     one, on explicit permission from the previous publisher that added
+     the old one.
+
+     The author(s) and publisher(s) of the Document do not by this
+     License give permission to use their names for publicity for or to
+     assert or imply endorsement of any Modified Version.
+
+  5. COMBINING DOCUMENTS
+
+     You may combine the Document with other documents released under
+     this License, under the terms defined in section 4 above for
+     modified versions, provided that you include in the combination all
+     of the Invariant Sections of all of the original documents,
+     unmodified, and list them all as Invariant Sections of your
+     combined work in its license notice, and that you preserve all
+     their Warranty Disclaimers.
+
+     The combined work need only contain one copy of this License, and
+     multiple identical Invariant Sections may be replaced with a single
+     copy.  If there are multiple Invariant Sections with the same name
+     but different contents, make the title of each such section unique
+     by adding at the end of it, in parentheses, the name of the
+     original author or publisher of that section if known, or else a
+     unique number.  Make the same adjustment to the section titles in
+     the list of Invariant Sections in the license notice of the
+     combined work.
+
+     In the combination, you must combine any sections Entitled
+     "History" in the various original documents, forming one section
+     Entitled "History"; likewise combine any sections Entitled
+     "Acknowledgements", and any sections Entitled "Dedications".  You
+     must delete all sections Entitled "Endorsements."
+
+  6. COLLECTIONS OF DOCUMENTS
+
+     You may make a collection consisting of the Document and other
+     documents released under this License, and replace the individual
+     copies of this License in the various documents with a single copy
+     that is included in the collection, provided that you follow the
+     rules of this License for verbatim copying of each of the documents
+     in all other respects.
+
+     You may extract a single document from such a collection, and
+     distribute it individually under this License, provided you insert
+     a copy of this License into the extracted document, and follow this
+     License in all other respects regarding verbatim copying of that
+     document.
+
+  7. AGGREGATION WITH INDEPENDENT WORKS
+
+     A compilation of the Document or its derivatives with other
+     separate and independent documents or works, in or on a volume of a
+     storage or distribution medium, is called an "aggregate" if the
+     copyright resulting from the compilation is not used to limit the
+     legal rights of the compilation's users beyond what the individual
+     works permit.  When the Document is included in an aggregate, this
+     License does not apply to the other works in the aggregate which
+     are not themselves derivative works of the Document.
+
+     If the Cover Text requirement of section 3 is applicable to these
+     copies of the Document, then if the Document is less than one half
+     of the entire aggregate, the Document's Cover Texts may be placed
+     on covers that bracket the Document within the aggregate, or the
+     electronic equivalent of covers if the Document is in electronic
+     form.  Otherwise they must appear on printed covers that bracket
+     the whole aggregate.
+
+  8. TRANSLATION
+
+     Translation is considered a kind of modification, so you may
+     distribute translations of the Document under the terms of section
+     4.  Replacing Invariant Sections with translations requires special
+     permission from their copyright holders, but you may include
+     translations of some or all Invariant Sections in addition to the
+     original versions of these Invariant Sections.  You may include a
+     translation of this License, and all the license notices in the
+     Document, and any Warranty Disclaimers, provided that you also
+     include the original English version of this License and the
+     original versions of those notices and disclaimers.  In case of a
+     disagreement between the translation and the original version of
+     this License or a notice or disclaimer, the original version will
+     prevail.
+
+     If a section in the Document is Entitled "Acknowledgements",
+     "Dedications", or "History", the requirement (section 4) to
+     Preserve its Title (section 1) will typically require changing the
+     actual title.
+
+  9. TERMINATION
+
+     You may not copy, modify, sublicense, or distribute the Document
+     except as expressly provided under this License.  Any attempt
+     otherwise to copy, modify, sublicense, or distribute it is void,
+     and will automatically terminate your rights under this License.
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly and
+     finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from you
+     under this License.  If your rights have been terminated and not
+     permanently reinstated, receipt of a copy of some or all of the
+     same material does not give you any rights to use it.
+
+  10. FUTURE REVISIONS OF THIS LICENSE
+
+     The Free Software Foundation may publish new, revised versions of
+     the GNU Free Documentation License from time to time.  Such new
+     versions will be similar in spirit to the present version, but may
+     differ in detail to address new problems or concerns.  See
+     <http://www.gnu.org/copyleft/>.
+
+     Each version of the License is given a distinguishing version
+     number.  If the Document specifies that a particular numbered
+     version of this License "or any later version" applies to it, you
+     have the option of following the terms and conditions either of
+     that specified version or of any later version that has been
+     published (not as a draft) by the Free Software Foundation.  If the
+     Document does not specify a version number of this License, you may
+     choose any version ever published (not as a draft) by the Free
+     Software Foundation.  If the Document specifies that a proxy can
+     decide which future versions of this License can be used, that
+     proxy's public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Document.
+
+  11. RELICENSING
+
+     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+     World Wide Web server that publishes copyrightable works and also
+     provides prominent facilities for anybody to edit those works.  A
+     public wiki that anybody can edit is an example of such a server.
+     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+     site means any set of copyrightable works thus published on the MMC
+     site.
+
+     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+     license published by Creative Commons Corporation, a not-for-profit
+     corporation with a principal place of business in San Francisco,
+     California, as well as future copyleft versions of that license
+     published by that same organization.
+
+     "Incorporate" means to publish or republish a Document, in whole or
+     in part, as part of another Document.
+
+     An MMC is "eligible for relicensing" if it is licensed under this
+     License, and if all works that were first published under this
+     License somewhere other than this MMC, and subsequently
+     incorporated in whole or in part into the MMC, (1) had no cover
+     texts or invariant sections, and (2) were thus incorporated prior
+     to November 1, 2008.
+
+     The operator of an MMC Site may republish an MMC contained in the
+     site under CC-BY-SA on the same site at any time before August 1,
+     2009, provided the MMC is eligible for relicensing.
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+       Copyright (C)  YEAR  YOUR NAME.
+       Permission is granted to copy, distribute and/or modify this document
+       under the terms of the GNU Free Documentation License, Version 1.3
+       or any later version published by the Free Software Foundation;
+       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+       Texts.  A copy of the license is included in the section entitled ``GNU
+       Free Documentation License''.
+
+   If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts."  line with this:
+
+         with the Invariant Sections being LIST THEIR TITLES, with
+         the Front-Cover Texts being LIST, and with the Back-Cover Texts
+         being LIST.
+
+   If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+   If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of free
+software license, such as the GNU General Public License, to permit
+their use in free software.

+1 Introduction
+**************
+
+Automake is a tool for automatically generating 'Makefile.in's from
+files called 'Makefile.am'.  Each 'Makefile.am' is basically a series of
+'make' variable definitions(1), with rules being thrown in occasionally.
+The generated 'Makefile.in's are compliant with the GNU Makefile
+standards.
+
+   The GNU Makefile Standards Document (*note (standards)Makefile
+Conventions::) is long, complicated, and subject to change.  The goal of
+Automake is to remove the burden of Makefile maintenance from the back
+of the individual GNU maintainer (and put it on the back of the Automake
+maintainers).
+
+   The typical Automake input file is simply a series of variable
+definitions.  Each such file is processed to create a 'Makefile.in'.
+
+   Automake does constrain a project in certain ways; for instance, it
+assumes that the project uses Autoconf (*note Introduction:
+(autoconf)Top.), and enforces certain restrictions on the 'configure.ac'
+contents.
+
+   Automake requires 'perl' in order to generate the 'Makefile.in's.
+However, the distributions created by Automake are fully GNU
+standards-compliant, and do not require 'perl' in order to be built.
+

+
+   (1) These variables are also called "make macros" in Make
+terminology, however in this manual we reserve the term "macro" for
+Autoconf's macros.

+2 An Introduction to the Autotools
+**********************************
+
+If you are new to Automake, maybe you know that it is part of a set of
+tools called _The Autotools_.  Maybe you've already delved into a
+package full of files named 'configure', 'configure.ac', 'Makefile.in',
+'Makefile.am', 'aclocal.m4', ..., some of them claiming to be _generated
+by_ Autoconf or Automake.  But the exact purpose of these files and
+their relations is probably fuzzy.  The goal of this chapter is to
+introduce you to this machinery, to show you how it works and how
+powerful it is.  If you've never installed or seen such a package, do
+not worry: this chapter will walk you through it.
+
+   If you need some teaching material, more illustrations, or a less
+'automake'-centered continuation, some slides for this introduction are
+available in Alexandre Duret-Lutz's Autotools Tutorial
+(http://www.lrde.epita.fr/~adl/autotools.html).  This chapter is the
+written version of the first part of his tutorial.

+
+2.1 Introducing the GNU Build System
+====================================
+
+It is a truth universally acknowledged, that as a developer in
+possession of a new package, you must be in want of a build system.
+
+   In the Unix world, such a build system is traditionally achieved
+using the command 'make' (*note Overview: (make)Top.).  You express the
+recipe to build your package in a 'Makefile'.  This file is a set of
+rules to build the files in the package.  For instance the program
+'prog' may be built by running the linker on the files 'main.o',
+'foo.o', and 'bar.o'; the file 'main.o' may be built by running the
+compiler on 'main.c'; etc.  Each time 'make' is run, it reads
+'Makefile', checks the existence and modification time of the files
+mentioned, decides what files need to be built (or rebuilt), and runs
+the associated commands.
+
+   When a package needs to be built on a different platform than the one
+it was developed on, its 'Makefile' usually needs to be adjusted.  For
+instance the compiler may have another name or require more options.  In
+1991, David J. MacKenzie got tired of customizing 'Makefile' for the 20
+platforms he had to deal with.  Instead, he handcrafted a little shell
+script called 'configure' to automatically adjust the 'Makefile' (*note
+Genesis: (autoconf)Genesis.).  Compiling his package was now as simple
+as running './configure && make'.
+
+   Today this process has been standardized in the GNU project.  The GNU
+Coding Standards (*note The Release Process: (standards)Managing
+Releases.) explains how each package of the GNU project should have a
+'configure' script, and the minimal interface it should have.  The
+'Makefile' too should follow some established conventions.  The result?
+A unified build system that makes all packages almost indistinguishable
+by the installer.  In its simplest scenario, all the installer has to do
+is to unpack the package, run './configure && make && make install', and
+repeat with the next package to install.
+
+   We call this build system the "GNU Build System", since it was grown
+out of the GNU project.  However it is used by a vast number of other
+packages: following any existing convention has its advantages.
+
+   The Autotools are tools that will create a GNU Build System for your
+package.  Autoconf mostly focuses on 'configure' and Automake on
+'Makefile's.  It is entirely possible to create a GNU Build System
+without the help of these tools.  However it is rather burdensome and
+error-prone.  We will discuss this again after some illustration of the
+GNU Build System in action.
+

+File: automake.info,  Node: Use Cases,  Next: Why Autotools,  Prev: GNU Build System,  Up: Autotools Introduction
+
+2.2 Use Cases for the GNU Build System
+======================================
+
+In this section we explore several use cases for the GNU Build System.
+You can replay all of these examples on the 'amhello-1.0.tar.gz' package
+distributed with Automake.  If Automake is installed on your system, you
+should find a copy of this file in
+'PREFIX/share/doc/automake/amhello-1.0.tar.gz', where PREFIX is the
+installation prefix specified during configuration (PREFIX defaults to
+'/usr/local', however if Automake was installed by some GNU/Linux
+distribution it most likely has been set to '/usr').  If you do not have
+a copy of Automake installed, you can find a copy of this file inside
+the 'doc/' directory of the Automake package.
+
+   Some of the following use cases present features that are in fact
+extensions to the GNU Build System.  Read: they are not specified by the
+GNU Coding Standards, but they are nonetheless part of the build system
+created by the Autotools.  To keep things simple, we do not point out
+the difference.  Our objective is to show you many of the features that
+the build system created by the Autotools will offer to you.

+
+2.2.1 Basic Installation
+------------------------
+
+The most common installation procedure looks as follows.
+
+     ~ % tar zxf amhello-1.0.tar.gz
+     ~ % cd amhello-1.0
+     ~/amhello-1.0 % ./configure
+     ...
+     config.status: creating Makefile
+     config.status: creating src/Makefile
+     ...
+     ~/amhello-1.0 % make
+     ...
+     ~/amhello-1.0 % make check
+     ...
+     ~/amhello-1.0 % su
+     Password:
+     /home/adl/amhello-1.0 # make install
+     ...
+     /home/adl/amhello-1.0 # exit
+     ~/amhello-1.0 % make installcheck
+     ...
+
+   The user first unpacks the package.  Here, and in the following
+examples, we will use the non-portable 'tar zxf' command for simplicity.
+On a system without GNU 'tar' installed, this command should read
+'gunzip -c amhello-1.0.tar.gz | tar xf -'.
+
+   The user then enters the newly created directory to run the
+'configure' script.  This script probes the system for various features,
+and finally creates the 'Makefile's.  In this toy example there are only
+two 'Makefile's, but in real-world projects, there may be many more,
+usually one 'Makefile' per directory.
+
+   It is now possible to run 'make'.  This will construct all the
+programs, libraries, and scripts that need to be constructed for the
+package.  In our example, this compiles the 'hello' program.  All files
+are constructed in place, in the source tree; we will see later how this
+can be changed.
+
+   'make check' causes the package's tests to be run.  This step is not
+mandatory, but it is often good to make sure the programs that have been
+built behave as they should, before you decide to install them.  Our
+example does not contain any tests, so running 'make check' is a no-op.
+
+   After everything has been built, and maybe tested, it is time to
+install it on the system.  That means copying the programs, libraries,
+header files, scripts, and other data files from the source directory to
+their final destination on the system.  The command 'make install' will
+do that.  However, by default everything will be installed in
+subdirectories of '/usr/local': binaries will go into '/usr/local/bin',
+libraries will end up in '/usr/local/lib', etc.  This destination is
+usually not writable by any user, so we assume that we have to become
+root before we can run 'make install'.  In our example, running 'make
+install' will copy the program 'hello' into '/usr/local/bin' and
+'README' into '/usr/local/share/doc/amhello'.
+
+   A last and optional step is to run 'make installcheck'.  This command
+may run tests on the installed files.  'make check' tests the files in
+the source tree, while 'make installcheck' tests their installed copies.
+The tests run by the latter can be different from those run by the
+former.  For instance, there are tests that cannot be run in the source
+tree.  Conversely, some packages are set up so that 'make installcheck'
+will run the very same tests as 'make check', only on different files
+(non-installed vs. installed).  It can make a difference, for instance
+when the source tree's layout is different from that of the
+installation.  Furthermore it may help to diagnose an incomplete
+installation.
+
+   Presently most packages do not have any 'installcheck' tests because
+the existence of 'installcheck' is little known, and its usefulness is
+neglected.  Our little toy package is no better: 'make installcheck'
+does nothing.

+
+2.2.2 Standard 'Makefile' Targets
+---------------------------------
+
+So far we have come across four ways to run 'make' in the GNU Build
+System: 'make', 'make check', 'make install', and 'make installcheck'.
+The words 'check', 'install', and 'installcheck', passed as arguments to
+'make', are called "targets".  'make' is a shorthand for 'make all',
+'all' being the default target in the GNU Build System.
+
+   Here is a list of the most useful targets that the GNU Coding
+Standards specify.
+
+'make all'
+     Build programs, libraries, documentation, etc. (same as 'make').
+'make install'
+     Install what needs to be installed, copying the files from the
+     package's tree to system-wide directories.
+'make install-strip'
+     Same as 'make install', then strip debugging symbols.  Some users
+     like to trade space for useful bug reports...
+'make uninstall'
+     The opposite of 'make install': erase the installed files.  (This
+     needs to be run from the same build tree that was installed.)
+'make clean'
+     Erase from the build tree the files built by 'make all'.
+'make distclean'
+     Additionally erase anything './configure' created.
+'make check'
+     Run the test suite, if any.
+'make installcheck'
+     Check the installed programs or libraries, if supported.
+'make dist'
+     Recreate 'PACKAGE-VERSION.tar.gz' from all the source files.
+
+
+File: automake.info,  Node: Standard Directory Variables,  Next: Standard Configuration Variables,  Prev: Standard Targets,  Up: Use Cases
+
+2.2.3 Standard Directory Variables
+----------------------------------
+
+The GNU Coding Standards also specify a hierarchy of variables to denote
+installation directories.  Some of these are:
+
+Directory variable   Default value
+-------------------------------------------------------
+'prefix'             '/usr/local'
+  'exec_prefix'      '${prefix}'
+    'bindir'         '${exec_prefix}/bin'
+    'libdir'         '${exec_prefix}/lib'
+    ...
+  'includedir'       '${prefix}/include'
+  'datarootdir'      '${prefix}/share'
+    'datadir'        '${datarootdir}'
+    'mandir'         '${datarootdir}/man'
+    'infodir'        '${datarootdir}/info'
+    'docdir'         '${datarootdir}/doc/${PACKAGE}'
+  ...
+
+   Each of these directories has a role which is often obvious from its
+name.  In a package, any installable file will be installed in one of
+these directories.  For instance in 'amhello-1.0', the program 'hello'
+is to be installed in BINDIR, the directory for binaries.  The default
+value for this directory is '/usr/local/bin', but the user can supply a
+different value when calling 'configure'.  Also the file 'README' will
+be installed into DOCDIR, which defaults to
+'/usr/local/share/doc/amhello'.
+
+   As a user, if you wish to install a package on your own account, you
+could proceed as follows:
+
+     ~/amhello-1.0 % ./configure --prefix ~/usr
+     ...
+     ~/amhello-1.0 % make
+     ...
+     ~/amhello-1.0 % make install
+     ...
+
+   This would install '~/usr/bin/hello' and
+'~/usr/share/doc/amhello/README'.
+
+   The list of all such directory options is shown by './configure
+--help'.

+File: automake.info,  Node: Standard Configuration Variables,  Next: config.site,  Prev: Standard Directory Variables,  Up: Use Cases
+
+2.2.4 Standard Configuration Variables
+--------------------------------------
+
+The GNU Coding Standards also define a set of standard configuration
+variables used during the build.  Here are some:
+
+'CC'
+     C compiler command
+'CFLAGS'
+     C compiler flags
+'CXX'
+     C++ compiler command
+'CXXFLAGS'
+     C++ compiler flags
+'LDFLAGS'
+     linker flags
+'CPPFLAGS'
+     C/C++ preprocessor flags
+...
+
+   'configure' usually does a good job at setting appropriate values for
+these variables, but there are cases where you may want to override
+them.  For instance you may have several versions of a compiler
+installed and would like to use another one, you may have header files
+installed outside the default search path of the compiler, or even
+libraries out of the way of the linker.
+
+   Here is how one would call 'configure' to force it to use 'gcc-3' as
+C compiler, use header files from '~/usr/include' when compiling, and
+libraries from '~/usr/lib' when linking.
+
+     ~/amhello-1.0 % ./configure --prefix ~/usr CC=gcc-3 \
+     CPPFLAGS=-I$HOME/usr/include LDFLAGS=-L$HOME/usr/lib
+
+   Again, a full list of these variables appears in the output of
+'./configure --help'.

+When installing several packages using the same setup, it can be
+convenient to create a file to capture common settings.  If a file named
+'PREFIX/share/config.site' exists, 'configure' will source it at the
+beginning of its execution.
+
+   Recall the command from the previous section:
+
+     ~/amhello-1.0 % ./configure --prefix ~/usr CC=gcc-3 \
+     CPPFLAGS=-I$HOME/usr/include LDFLAGS=-L$HOME/usr/lib
+
+   Assuming we are installing many package in '~/usr', and will always
+want to use these definitions of 'CC', 'CPPFLAGS', and 'LDFLAGS', we can
+automate this by creating the following '~/usr/share/config.site' file:
+
+     test -z "$CC" && CC=gcc-3
+     test -z "$CPPFLAGS" && CPPFLAGS=-I$HOME/usr/include
+     test -z "$LDFLAGS" && LDFLAGS=-L$HOME/usr/lib
+
+   Now, any time a 'configure' script is using the '~/usr' prefix, it
+will execute the above 'config.site' and define these three variables.
+
+     ~/amhello-1.0 % ./configure --prefix ~/usr
+     configure: loading site script /home/adl/usr/share/config.site
+     ...

+2.2.6 Parallel Build Trees (a.k.a. VPATH Builds)
+------------------------------------------------
+
+The GNU Build System distinguishes two trees: the source tree, and the
+build tree.
+
+   The source tree is rooted in the directory containing 'configure'.
+It contains all the sources files (those that are distributed), and may
+be arranged using several subdirectories.
+
+   The build tree is rooted in the directory in which 'configure' was
+run, and is populated with all object files, programs, libraries, and
+other derived files built from the sources (and hence not distributed).
+The build tree usually has the same subdirectory layout as the source
+tree; its subdirectories are created automatically by the build system.
+
+   If 'configure' is executed in its own directory, the source and build
+trees are combined: derived files are constructed in the same
+directories as their sources.  This was the case in our first
+installation example (*note Basic Installation::).
+
+   A common request from users is that they want to confine all derived
+files to a single directory, to keep their source directories
+uncluttered.  Here is how we could run 'configure' to build everything
+in a subdirectory called 'build/'.
+
+     ~ % tar zxf ~/amhello-1.0.tar.gz
+     ~ % cd amhello-1.0
+     ~/amhello-1.0 % mkdir build && cd build
+     ~/amhello-1.0/build % ../configure
+     ...
+     ~/amhello-1.0/build % make
+     ...
+
+   These setups, where source and build trees are different, are often
+called "parallel builds" or "VPATH builds".  The expression _parallel
+build_ is misleading: the word _parallel_ is a reference to the way the
+build tree shadows the source tree, it is not about some concurrency in
+the way build commands are run.  For this reason we refer to such setups
+using the name _VPATH builds_ in the following.  _VPATH_ is the name of
+the 'make' feature used by the 'Makefile's to allow these builds (*note
+'VPATH' Search Path for All Prerequisites: (make)General Search.).
+
+   VPATH builds have other interesting uses.  One is to build the same
+sources with multiple configurations.  For instance:
+
+     ~ % tar zxf ~/amhello-1.0.tar.gz
+     ~ % cd amhello-1.0
+     ~/amhello-1.0 % mkdir debug optim && cd debug
+     ~/amhello-1.0/debug % ../configure CFLAGS='-g -O0'
+     ...
+     ~/amhello-1.0/debug % make
+     ...
+     ~/amhello-1.0/debug % cd ../optim
+     ~/amhello-1.0/optim % ../configure CFLAGS='-O3 -fomit-frame-pointer'
+     ...
+     ~/amhello-1.0/optim % make
+     ...
+
+   With network file systems, a similar approach can be used to build
+the same sources on different machines.  For instance, suppose that the
+sources are installed on a directory shared by two hosts: 'HOST1' and
+'HOST2', which may be different platforms.
+
+     ~ % cd /nfs/src
+     /nfs/src % tar zxf ~/amhello-1.0.tar.gz
+
+   On the first host, you could create a local build directory:
+     [HOST1] ~ % mkdir /tmp/amh && cd /tmp/amh
+     [HOST1] /tmp/amh % /nfs/src/amhello-1.0/configure
+     ...
+     [HOST1] /tmp/amh % make && sudo make install
+     ...
+
+(Here we assume that the installer has configured 'sudo' so it can
+execute 'make install' with root privileges; it is more convenient than
+using 'su' like in *note Basic Installation::).
+
+   On the second host, you would do exactly the same, possibly at the
+same time:
+     [HOST2] ~ % mkdir /tmp/amh && cd /tmp/amh
+     [HOST2] /tmp/amh % /nfs/src/amhello-1.0/configure
+     ...
+     [HOST2] /tmp/amh % make && sudo make install
+     ...
+
+   In this scenario, nothing forbids the '/nfs/src/amhello-1.0'
+directory from being read-only.  In fact VPATH builds are also a means
+of building packages from a read-only medium such as a CD-ROM. (The FSF
+used to sell CD-ROM with unpacked source code, before the GNU project
+grew so big.)

+
+2.2.7 Two-Part Installation
+---------------------------
+
+In our last example (*note VPATH Builds::), a source tree was shared by
+two hosts, but compilation and installation were done separately on each
+host.
+
+   The GNU Build System also supports networked setups where part of the
+installed files should be shared amongst multiple hosts.  It does so by
+distinguishing architecture-dependent files from
+architecture-independent files, and providing two 'Makefile' targets to
+install each of these classes of files.
+
+   These targets are 'install-exec' for architecture-dependent files and
+'install-data' for architecture-independent files.  The command we used
+up to now, 'make install', can be thought of as a shorthand for 'make
+install-exec install-data'.
+
+   From the GNU Build System point of view, the distinction between
+architecture-dependent files and architecture-independent files is based
+exclusively on the directory variable used to specify their installation
+destination.  In the list of directory variables we provided earlier
+(*note Standard Directory Variables::), all the variables based on
+EXEC-PREFIX designate architecture-dependent directories whose files
+will be installed by 'make install-exec'.  The others designate
+architecture-independent directories and will serve files installed by
+'make install-data'.  *Note The Two Parts of Install::, for more
+details.
+
+   Here is how we could revisit our two-host installation example,
+assuming that (1) we want to install the package directly in '/usr', and
+(2) the directory '/usr/share' is shared by the two hosts.
+
+   On the first host we would run
+     [HOST1] ~ % mkdir /tmp/amh && cd /tmp/amh
+     [HOST1] /tmp/amh % /nfs/src/amhello-1.0/configure --prefix /usr
+     ...
+     [HOST1] /tmp/amh % make && sudo make install
+     ...
+
+   On the second host, however, we need only install the
+architecture-specific files.
+     [HOST2] ~ % mkdir /tmp/amh && cd /tmp/amh
+     [HOST2] /tmp/amh % /nfs/src/amhello-1.0/configure --prefix /usr
+     ...
+     [HOST2] /tmp/amh % make && sudo make install-exec
+     ...
+
+   In packages that have installation checks, it would make sense to run
+'make installcheck' (*note Basic Installation::) to verify that the
+package works correctly despite the apparent partial installation.
+

+
+2.2.8 Cross-Compilation
+-----------------------
+
+To "cross-compile" is to build on one platform a binary that will run on
+another platform.  When speaking of cross-compilation, it is important
+to distinguish between the "build platform" on which the compilation is
+performed, and the "host platform" on which the resulting executable is
+expected to run.  The following 'configure' options are used to specify
+each of them:
+
+'--build=BUILD'
+     The system on which the package is built.
+'--host=HOST'
+     The system where built programs and libraries will run.
+
+   When the '--host' is used, 'configure' will search for the
+cross-compiling suite for this platform.  Cross-compilation tools
+commonly have their target architecture as prefix of their name.  For
+instance my cross-compiler for MinGW32 has its binaries called
+'i586-mingw32msvc-gcc', 'i586-mingw32msvc-ld', 'i586-mingw32msvc-as',
+etc.
+
+   Here is how we could build 'amhello-1.0' for 'i586-mingw32msvc' on a
+GNU/Linux PC.
+
+     ~/amhello-1.0 % ./configure --build i686-pc-linux-gnu --host i586-mingw32msvc
+     checking for a BSD-compatible install... /usr/bin/install -c
+     checking whether build environment is sane... yes
+     checking for gawk... gawk
+     checking whether make sets $(MAKE)... yes
+     checking for i586-mingw32msvc-strip... i586-mingw32msvc-strip
+     checking for i586-mingw32msvc-gcc... i586-mingw32msvc-gcc
+     checking for C compiler default output file name... a.exe
+     checking whether the C compiler works... yes
+     checking whether we are cross compiling... yes
+     checking for suffix of executables... .exe
+     checking for suffix of object files... o
+     checking whether we are using the GNU C compiler... yes
+     checking whether i586-mingw32msvc-gcc accepts -g... yes
+     checking for i586-mingw32msvc-gcc option to accept ANSI C...
+     ...
+     ~/amhello-1.0 % make
+     ...
+     ~/amhello-1.0 % cd src; file hello.exe
+     hello.exe: MS Windows PE 32-bit Intel 80386 console executable not relocatable
+
+   The '--host' and '--build' options are usually all we need for
+cross-compiling.  The only exception is if the package being built is
+itself a cross-compiler: we need a third option to specify its target
+architecture.
+
+'--target=TARGET'
+     When building compiler tools: the system for which the tools will
+     create output.
+
+   For instance when installing GCC, the GNU Compiler Collection, we can
+use '--target=TARGET' to specify that we want to build GCC as a
+cross-compiler for TARGET.  Mixing '--build' and '--target', we can
+actually cross-compile a cross-compiler; such a three-way
+cross-compilation is known as a "Canadian cross".

+   *Note Specifying the System Type: (autoconf)Specifying Names, for
+more information about these 'configure' options.

+
+2.2.9 Renaming Programs at Install Time
+---------------------------------------
+
+The GNU Build System provides means to automatically rename executables
+and manpages before they are installed (*note Man Pages::).  This is
+especially convenient when installing a GNU package on a system that
+already has a proprietary implementation you do not want to overwrite.
+For instance, you may want to install GNU 'tar' as 'gtar' so you can
+distinguish it from your vendor's 'tar'.
+
+   This can be done using one of these three 'configure' options.
+
+'--program-prefix=PREFIX'
+     Prepend PREFIX to installed program names.
+'--program-suffix=SUFFIX'
+     Append SUFFIX to installed program names.
+'--program-transform-name=PROGRAM'
+     Run 'sed PROGRAM' on installed program names.
+
+   The following commands would install 'hello' as
+'/usr/local/bin/test-hello', for instance.
+
+     ~/amhello-1.0 % ./configure --program-prefix test-
+     ...
+     ~/amhello-1.0 % make
+     ...
+     ~/amhello-1.0 % sudo make install
+     ...

+
+2.2.10 Building Binary Packages Using DESTDIR
+---------------------------------------------
+
+The GNU Build System's 'make install' and 'make uninstall' interface
+does not exactly fit the needs of a system administrator who has to
+deploy and upgrade packages on lots of hosts.  In other words, the GNU
+Build System does not replace a package manager.
+
+   Such package managers usually need to know which files have been
+installed by a package, so a mere 'make install' is inappropriate.
+
+   The 'DESTDIR' variable can be used to perform a staged installation.
+The package should be configured as if it was going to be installed in
+its final location (e.g., '--prefix /usr'), but when running 'make
+install', the 'DESTDIR' should be set to the absolute name of a
+directory into which the installation will be diverted.  From this
+directory it is easy to review which files are being installed where,
+and finally copy them to their final location by some means.
+
+   For instance here is how we could create a binary package containing
+a snapshot of all the files to be installed.
+
+     ~/amhello-1.0 % ./configure --prefix /usr
+     ...
+     ~/amhello-1.0 % make
+     ...
+     ~/amhello-1.0 % make DESTDIR=$HOME/inst install
+     ...
+     ~/amhello-1.0 % cd ~/inst
+     ~/inst % find . -type f -print > ../files.lst
+     ~/inst % tar zcvf ~/amhello-1.0-i686.tar.gz `cat ../files.lst`
+     ./usr/bin/hello
+     ./usr/share/doc/amhello/README
+
+   After this example, 'amhello-1.0-i686.tar.gz' is ready to be
+uncompressed in '/' on many hosts.  (Using '`cat ../files.lst`' instead
+of '.' as argument for 'tar' avoids entries for each subdirectory in the
+archive: we would not like 'tar' to restore the modification time of
+'/', '/usr/', etc.)
+
+   Note that when building packages for several architectures, it might
+be convenient to use 'make install-data' and 'make install-exec' (*note
+Two-Part Install::) to gather architecture-independent files in a single
+package.
+
+   *Note Install::, for more information.

+File: automake.info,  Node: Preparing Distributions,  Next: Dependency Tracking,  Prev: DESTDIR,  Up: Use Cases
+
+2.2.11 Preparing Distributions
+------------------------------
+
+We have already mentioned 'make dist'.  This target collects all your
+source files and the necessary parts of the build system to create a
+tarball named 'PACKAGE-VERSION.tar.gz'.
+
+   Another, more useful command is 'make distcheck'.  The 'distcheck'
+target constructs 'PACKAGE-VERSION.tar.gz' just as well as 'dist', but
+it additionally ensures most of the use cases presented so far work:
+
+   * It attempts a full compilation of the package (*note Basic
+     Installation::), unpacking the newly constructed tarball, running
+     'make', 'make check', 'make install', as well as 'make
+     installcheck', and even 'make dist',
+   * it tests VPATH builds with read-only source tree (*note VPATH
+     Builds::),
+   * it makes sure 'make clean', 'make distclean', and 'make uninstall'
+     do not omit any file (*note Standard Targets::),
+   * and it checks that 'DESTDIR' installations work (*note DESTDIR::).
+
+   All of these actions are performed in a temporary subdirectory, so
+that no root privileges are required.
+
+   Releasing a package that fails 'make distcheck' means that one of the
+scenarios we presented will not work and some users will be
+disappointed.  Therefore it is a good practice to release a package only
+after a successful 'make distcheck'.  This of course does not imply that
+the package will be flawless, but at least it will prevent some of the
+embarrassing errors you may find in packages released by people who have
+never heard about 'distcheck' (like 'DESTDIR' not working because of a
+typo, or a distributed file being erased by 'make clean', or even
+'VPATH' builds not working).

+File: automake.info,  Node: Dependency Tracking,  Next: Nested Packages,  Prev: Preparing Distributions,  Up: Use Cases
+
+2.2.12 Automatic Dependency Tracking
+------------------------------------
+
+Dependency tracking is performed as a side-effect of compilation.  Each
+time the build system compiles a source file, it computes its list of
+dependencies (in C these are the header files included by the source
+being compiled).  Later, any time 'make' is run and a dependency appears
+to have changed, the dependent files will be rebuilt.
+
+   Automake generates code for automatic dependency tracking by default,
+unless the developer chooses to override it; for more information, *note
+Dependencies::.
+
+   When 'configure' is executed, you can see it probing each compiler
+for the dependency mechanism it supports (several mechanisms can be
+used):
+
+     ~/amhello-1.0 % ./configure --prefix /usr
+     ...
+     checking dependency style of gcc... gcc3
+     ...
+
+   Because dependencies are only computed as a side-effect of the
+compilation, no dependency information exists the first time a package
+is built.  This is OK because all the files need to be built anyway:
+'make' does not have to decide which files need to be rebuilt.  In fact,
+dependency tracking is completely useless for one-time builds and there
+is a 'configure' option to disable this:
+
+'--disable-dependency-tracking'
+     Speed up one-time builds.
+
+   Some compilers do not offer any practical way to derive the list of
+dependencies as a side-effect of the compilation, requiring a separate
+run (maybe of another tool) to compute these dependencies.  The
+performance penalty implied by these methods is important enough to
+disable them by default.  The option '--enable-dependency-tracking' must
+be passed to 'configure' to activate them.
+
+'--enable-dependency-tracking'
+     Do not reject slow dependency extractors.
+
+   *Note Dependency Tracking Evolution: (automake-history)Dependency
+Tracking Evolution, for some discussion about the different dependency
+tracking schemes used by Automake over the years.

+
+2.2.13 Nested Packages
+----------------------
+
+Although nesting packages isn't something we would recommend to someone
+who is discovering the Autotools, it is a nice feature worthy of mention
+in this small advertising tour.
+
+   Autoconfiscated packages (that means packages whose build system have
+been created by Autoconf and friends) can be nested to arbitrary depth.
+
+   A typical setup is that package A will distribute one of the
+libraries it needs in a subdirectory.  This library B is a complete
+package with its own GNU Build System.  The 'configure' script of A will
+run the 'configure' script of B as part of its execution, building and
+installing A will also build and install B. Generating a distribution
+for A will also include B.
+
+   It is possible to gather several packages like this.  GCC is a heavy
+user of this feature.  This gives installers a single package to
+configure, build and install, while it allows developers to work on
+subpackages independently.
+
+   When configuring nested packages, the 'configure' options given to
+the top-level 'configure' are passed recursively to nested 'configure's.
+A package that does not understand an option will ignore it, assuming it
+is meaningful to some other package.
+
+   The command 'configure --help=recursive' can be used to display the
+options supported by all the included packages.

+2.3 How Autotools Help
+======================
+
+There are several reasons why you may not want to implement the GNU
+Build System yourself (read: write a 'configure' script and 'Makefile's
+yourself).
+
+   * As we have seen, the GNU Build System has a lot of features (*note
+     Use Cases::).  Some users may expect features you have not
+     implemented because you did not need them.
+   * Implementing these features portably is difficult and exhausting.
+     Think of writing portable shell scripts, and portable 'Makefile's,
+     for systems you may not have handy.  *Note Portable Shell
+     Programming: (autoconf)Portable Shell, to convince yourself.
+   * You will have to upgrade your setup to follow changes to the GNU
+     Coding Standards.
+
+   The GNU Autotools take all this burden off your back and provide:
+
+   * Tools to create a portable, complete, and self-contained GNU Build
+     System, from simple instructions.  _Self-contained_ meaning the
+     resulting build system does not require the GNU Autotools.
+   * A central place where fixes and improvements are made: a bug-fix
+     for a portability issue will benefit every package.
+
+   Yet there also exist reasons why you may want NOT to use the
+Autotools...  For instance you may be already using (or used to) another
+incompatible build system.  Autotools will only be useful if you do
+accept the concepts of the GNU Build System.  People who have their own
+idea of how a build system should work will feel frustrated by the
+Autotools.

+2.4.1 Creating 'amhello-1.0.tar.gz'
+-----------------------------------
+
+Here is how we can recreate 'amhello-1.0.tar.gz' from scratch.  The
+package is simple enough so that we will only need to write 5 files.
+(You may copy them from the final 'amhello-1.0.tar.gz' that is
+distributed with Automake if you do not want to write them.)
+
+   Create the following files in an empty directory.
+
+   * 'src/main.c' is the source file for the 'hello' program.  We store
+     it in the 'src/' subdirectory, because later, when the package
+     evolves, it will ease the addition of a 'man/' directory for man
+     pages, a 'data/' directory for data files, etc.
+          ~/amhello % cat src/main.c
+          #include <config.h>
+          #include <stdio.h>
+
+          int
+          main (void)
+          {
+            puts ("Hello World!");
+            puts ("This is " PACKAGE_STRING ".");
+            return 0;
+          }
+
+   * 'README' contains some very limited documentation for our little
+     package.
+          ~/amhello % cat README
+          This is a demonstration package for GNU Automake.
+          Type 'info Automake' to read the Automake manual.
+
+   * 'Makefile.am' and 'src/Makefile.am' contain Automake instructions
+     for these two directories.
+
+          ~/amhello % cat src/Makefile.am
+          bin_PROGRAMS = hello
+          hello_SOURCES = main.c
+          ~/amhello % cat Makefile.am
+          SUBDIRS = src
+          dist_doc_DATA = README
+
+   * Finally, 'configure.ac' contains Autoconf instructions to create
+     the 'configure' script.
+
+          ~/amhello % cat configure.ac
+          AC_INIT([amhello], [1.0], [bug-automake@gnu.org])
+          AM_INIT_AUTOMAKE([-Wall -Werror foreign])
+          AC_PROG_CC
+          AC_CONFIG_HEADERS([config.h])
+          AC_CONFIG_FILES([
+           Makefile
+           src/Makefile
+          ])
+          AC_OUTPUT
+
+   Once you have these five files, it is time to run the Autotools to
+instantiate the build system.  Do this using the 'autoreconf' command as
+follows:
+
+     ~/amhello % autoreconf --install
+     configure.ac: installing './install-sh'
+     configure.ac: installing './missing'
+     configure.ac: installing './compile'
+     src/Makefile.am: installing './depcomp'
+
+   At this point the build system is complete.
+
+   In addition to the three scripts mentioned in its output, you can see
+that 'autoreconf' created four other files: 'configure', 'config.h.in',
+'Makefile.in', and 'src/Makefile.in'.  The latter three files are
+templates that will be adapted to the system by 'configure' under the
+names 'config.h', 'Makefile', and 'src/Makefile'.  Let's do this:
+

+Build System does not exist.  When you later change some instructions in
+a 'Makefile.am' or 'configure.ac', the relevant part of the build system
+will be regenerated automatically when you execute 'make'.
+
+   'autoreconf' is a script that calls 'autoconf', 'automake', and a
+bunch of other commands in the right order.  If you are beginning with
+these tools, it is not important to figure out in which order all of
+these tools should be invoked and why.  However, because Autoconf and
+Automake have separate manuals, the important point to understand is
+that 'autoconf' is in charge of creating 'configure' from
+'configure.ac', while 'automake' is in charge of creating 'Makefile.in's
+from 'Makefile.am's and 'configure.ac'.  This should at least direct you
+to the right manual when seeking answers.

+
+2.4.2 'amhello''s 'configure.ac' Setup Explained
+------------------------------------------------
+
+Let us begin with the contents of 'configure.ac'.
+
+     AC_INIT([amhello], [1.0], [bug-automake@gnu.org])
+     AM_INIT_AUTOMAKE([-Wall -Werror foreign])
+     AC_PROG_CC
+     AC_CONFIG_HEADERS([config.h])
+     AC_CONFIG_FILES([
+      Makefile
+      src/Makefile
+     ])
+     AC_OUTPUT
+
+   This file is read by both 'autoconf' (to create 'configure') and
+'automake' (to create the various 'Makefile.in's).  It contains a series
+of M4 macros that will be expanded as shell code to finally form the
+'configure' script.  We will not elaborate on the syntax of this file,
+because the Autoconf manual has a whole section about it (*note Writing
+'configure.ac': (autoconf)Writing Autoconf Input.).
+
+   The macros prefixed with 'AC_' are Autoconf macros, documented in the
+Autoconf manual (*note Autoconf Macro Index: (autoconf)Autoconf Macro
+Index.).  The macros that start with 'AM_' are Automake macros,
+documented later in this manual (*note Macro Index::).
+
+   The first two lines of 'configure.ac' initialize Autoconf and
+Automake.  'AC_INIT' takes in as parameters the name of the package, its
+version number, and a contact address for bug-reports about the package
+(this address is output at the end of './configure --help', for
+instance).  When adapting this setup to your own package, by all means
+please do not blindly copy Automake's address: use the mailing list of
+your package, or your own mail address.
+
+   The argument to 'AM_INIT_AUTOMAKE' is a list of options for
+'automake' (*note Options::).  '-Wall' and '-Werror' ask 'automake' to
+turn on all warnings and report them as errors.  We are speaking of
+*Automake* warnings here, such as dubious instructions in 'Makefile.am'.
+This has absolutely nothing to do with how the compiler will be called,
+even though it may support options with similar names.  Using '-Wall
+-Werror' is a safe setting when starting to work on a package: you do
+not want to miss any issues.  Later you may decide to relax things a
+bit.  The 'foreign' option tells Automake that this package will not
+follow the GNU Standards.  GNU packages should always distribute
+additional files such as 'ChangeLog', 'AUTHORS', etc.  We do not want
+'automake' to complain about these missing files in our small example.
+
+   The 'AC_PROG_CC' line causes the 'configure' script to search for a C
+compiler and define the variable 'CC' with its name.  The
+'src/Makefile.in' file generated by Automake uses the variable 'CC' to
+build 'hello', so when 'configure' creates 'src/Makefile' from
+'src/Makefile.in', it will define 'CC' with the value it has found.  If
+Automake is asked to create a 'Makefile.in' that uses 'CC' but
+'configure.ac' does not define it, it will suggest you add a call to
+'AC_PROG_CC'.
+
+   The 'AC_CONFIG_HEADERS([config.h])' invocation causes the 'configure'
+script to create a 'config.h' file gathering '#define's defined by other
+macros in 'configure.ac'.  In our case, the 'AC_INIT' macro already
+defined a few of them.  Here is an excerpt of 'config.h' after
+'configure' has run:
+
+     ...
+     /* Define to the address where bug reports for this package should be sent. */
+     #define PACKAGE_BUGREPORT "bug-automake@gnu.org"
+
+     /* Define to the full name and version of this package. */
+     #define PACKAGE_STRING "amhello 1.0"
+     ...
+
+   As you probably noticed, 'src/main.c' includes 'config.h' so it can
+use 'PACKAGE_STRING'.  In a real-world project, 'config.h' can grow
+really big, with one '#define' per feature probed on the system.
+
+   The 'AC_CONFIG_FILES' macro declares the list of files that
+'configure' should create from their '*.in' templates.  Automake also
+scans this list to find the 'Makefile.am' files it must process.  (This
+is important to remember: when adding a new directory to your project,
+you should add its 'Makefile' to this list, otherwise Automake will
+never process the new 'Makefile.am' you wrote in that directory.)
+
+   Finally, the 'AC_OUTPUT' line is a closing command that actually
+produces the part of the script in charge of creating the files
+registered with 'AC_CONFIG_HEADERS' and 'AC_CONFIG_FILES'.
+
+   When starting a new project, we suggest you start with such a simple
+'configure.ac', and gradually add the other tests it requires.  The
+command 'autoscan' can also suggest a few of the tests your package may
+need (*note Using 'autoscan' to Create 'configure.ac':
+(autoconf)autoscan Invocation.).

+
+2.4.3 'amhello''s 'Makefile.am' Setup Explained
+-----------------------------------------------
+
+We now turn to 'src/Makefile.am'.  This file contains Automake
+instructions to build and install 'hello'.
+
+     bin_PROGRAMS = hello
+     hello_SOURCES = main.c
+
+   A 'Makefile.am' has the same syntax as an ordinary 'Makefile'.  When
+'automake' processes a 'Makefile.am' it copies the entire file into the
+output 'Makefile.in' (that will be later turned into 'Makefile' by
+'configure') but will react to certain variable definitions by
+generating some build rules and other variables.  Often 'Makefile.am's
+contain only a list of variable definitions as above, but they can also
+contain other variable and rule definitions that 'automake' will pass
+along without interpretation.
+
+   Variables that end with '_PROGRAMS' are special variables that list
+programs that the resulting 'Makefile' should build.  In Automake speak,
+this '_PROGRAMS' suffix is called a "primary"; Automake recognizes other
+primaries such as '_SCRIPTS', '_DATA', '_LIBRARIES', etc. corresponding
+to different types of files.
+
+   The 'bin' part of the 'bin_PROGRAMS' tells 'automake' that the
+resulting programs should be installed in BINDIR.  Recall that the GNU
+Build System uses a set of variables to denote destination directories
+and allow users to customize these locations (*note Standard Directory
+Variables::).  Any such directory variable can be put in front of a
+primary (omitting the 'dir' suffix) to tell 'automake' where to install
+the listed files.
+
+   Programs need to be built from source files, so for each program
+'PROG' listed in a '_PROGRAMS' variable, 'automake' will look for
+another variable named 'PROG_SOURCES' listing its source files.  There
+may be more than one source file: they will all be compiled and linked
+together.
+
+   Automake also knows that source files need to be distributed when
+creating a tarball (unlike built programs).  So a side-effect of this
+'hello_SOURCES' declaration is that 'main.c' will be part of the tarball
+created by 'make dist'.
+
+   Finally here are some explanations regarding the top-level
+'Makefile.am'.
+
+     SUBDIRS = src
+     dist_doc_DATA = README
+
+   'SUBDIRS' is a special variable listing all directories that 'make'
+should recurse into before processing the current directory.  So this
+line is responsible for 'make' building 'src/hello' even though we run
+it from the top-level.  This line also causes 'make install' to install
+'src/hello' before installing 'README' (not that this order matters).
+
+   The line 'dist_doc_DATA = README' causes 'README' to be distributed
+and installed in DOCDIR.  Files listed with the '_DATA' primary are not
+automatically part of the tarball built with 'make dist', so we add the
+'dist_' prefix so they get distributed.  However, for 'README' it would
+not have been necessary: 'automake' automatically distributes any
+'README' file it encounters (the list of other files automatically
+distributed is presented by 'automake --help').  The only important
+effect of this second line is therefore to install 'README' during 'make
+install'.
+
+   One thing not covered in this example is accessing the installation
+directory values (*note Standard Directory Variables::) from your
+program code, that is, converting them into defined macros.  For this,
+*note (autoconf)Defining Directories::.

+File: automake.info,  Node: General Operation,  Next: Strictness,  Up: Generalities
+
+3.1 General Operation
+=====================
+
+Automake works by reading a 'Makefile.am' and generating a
+'Makefile.in'.  Certain variables and rules defined in the 'Makefile.am'
+instruct Automake to generate more specialized code; for instance, a
+'bin_PROGRAMS' variable definition will cause rules for compiling and
+linking programs to be generated.
+
+   The variable definitions and rules in the 'Makefile.am' are copied
+mostly verbatim into the generated file, with all variable definitions
+preceding all rules.  This allows you to add almost arbitrary code into
+the generated 'Makefile.in'.  For instance, the Automake distribution
+includes a non-standard rule for the 'git-dist' target, which the
+Automake maintainer uses to make distributions from the source control
+system.
+
+   Note that most GNU make extensions are not recognized by Automake.
+Using such extensions in a 'Makefile.am' will lead to errors or
+confusing behavior.
+
+   A special exception is that the GNU make append operator, '+=', is
+supported.  This operator appends its right hand argument to the
+variable specified on the left.  Automake will translate the operator
+into an ordinary '=' operator; '+=' will thus work with any make
+program.
+
+   Automake tries to keep comments grouped with any adjoining rules or
+variable definitions.
+
+   Generally, Automake is not particularly smart in the parsing of
+unusual Makefile constructs, so you're advised to avoid fancy constructs
+or "creative" use of whitespaces.  For example, <TAB> characters cannot
+be used between a target name and the following "':'" character, and
+variable assignments shouldn't be indented with <TAB> characters.  Also,
+using more complex macro in target names can cause trouble:
+
+     % cat Makefile.am
+     $(FOO:=x): bar
+     % automake
+     Makefile.am:1: bad characters in variable name '$(FOO'
+     Makefile.am:1: ':='-style assignments are not portable
+
+   A rule defined in 'Makefile.am' generally overrides any such rule of
+a similar name that would be automatically generated by 'automake'.
+Although this is a supported feature, it is generally best to avoid
+making use of it, as sometimes the generated rules are very particular.
+
+   Similarly, a variable defined in 'Makefile.am' or 'AC_SUBST'ed from
+'configure.ac' will override any definition of the variable that
+'automake' would ordinarily create.  This feature is more often useful
+than the ability to override a rule.  Be warned that many of the
+variables generated by 'automake' are considered to be for internal use
+only, and their names might change in future releases.
+
+   When examining a variable definition, Automake will recursively
+examine variables referenced in the definition.  For example, if
+Automake is looking at the content of 'foo_SOURCES' in this snippet
+
+     xs = a.c b.c
+     foo_SOURCES = c.c $(xs)
+
+   it would use the files 'a.c', 'b.c', and 'c.c' as the contents of
+'foo_SOURCES'.
+
+   Automake also allows a form of comment that is _not_ copied into the
+output; all lines beginning with '##' (leading spaces allowed) are
+completely ignored by Automake.
+
+   It is customary to make the first line of 'Makefile.am' read:
+
+     ## Process this file with automake to produce Makefile.in
+

+File: automake.info,  Node: Strictness,  Next: Uniform,  Prev: General Operation,  Up: Generalities
+
+3.2 Strictness
+==============
+
+While Automake is intended to be used by maintainers of GNU packages, it
+does make some effort to accommodate those who wish to use it, but do
+not want to use all the GNU conventions.
+
+   To this end, Automake supports three levels of "strictness"--the
+strictness indicating how stringently Automake should check standards
+conformance.
+
+   The valid strictness levels are:
+
+'foreign'
+     Automake will check for only those things that are absolutely
+     required for proper operations.  For instance, whereas GNU
+     standards dictate the existence of a 'NEWS' file, it will not be
+     required in this mode.  This strictness will also turn off some
+     warnings by default (among them, portability warnings).  The name
+     comes from the fact that Automake is intended to be used for GNU
+     programs; these relaxed rules are not the standard mode of
+     operation.
+
+'gnu'
+     Automake will check--as much as possible--for compliance to the GNU
+     standards for packages.  This is the default.
+
+'gnits'
+     Automake will check for compliance to the as-yet-unwritten "Gnits
+     standards".  These are based on the GNU standards, but are even
+     more detailed.  Unless you are a Gnits standards contributor, it is
+     recommended that you avoid this option until such time as the Gnits
+     standard is actually published (which may never happen).
+
+   *Note Gnits::, for more information on the precise implications of
+the strictness level.

+
+3.3 The Uniform Naming Scheme
+=============================
+
+Automake variables generally follow a "uniform naming scheme" that makes
+it easy to decide how programs (and other derived objects) are built,
+and how they are installed.  This scheme also supports 'configure' time
+determination of what should be built.
+
+   At 'make' time, certain variables are used to determine which objects
+are to be built.  The variable names are made of several pieces that are
+concatenated together.
+
+   The piece that tells 'automake' what is being built is commonly
+called the "primary".  For instance, the primary 'PROGRAMS' holds a list
+of programs that are to be compiled and linked.
+
+   A different set of names is used to decide where the built objects
+should be installed.  These names are prefixes to the primary, and they
+indicate which standard directory should be used as the installation
+directory.  The standard directory names are given in the GNU standards
+(*note (standards)Directory Variables::).  Automake extends this list
+with 'pkgdatadir', 'pkgincludedir', 'pkglibdir', and 'pkglibexecdir';
+these are the same as the non-'pkg' versions, but with '$(PACKAGE)'
+appended.  For instance, 'pkglibdir' is defined as
+'$(libdir)/$(PACKAGE)'.
+
+   For each primary, there is one additional variable named by
+prepending 'EXTRA_' to the primary name.  This variable is used to list
+objects that may or may not be built, depending on what 'configure'
+decides.  This variable is required because Automake must statically
+know the entire list of objects that may be built in order to generate a
+'Makefile.in' that will work in all cases.
+
+   For instance, 'cpio' decides at configure time which programs should
+be built.  Some of the programs are installed in 'bindir', and some are
+installed in 'sbindir':
+
+     EXTRA_PROGRAMS = mt rmt
+     bin_PROGRAMS = cpio pax
+     sbin_PROGRAMS = $(MORE_PROGRAMS)
+
+   Defining a primary without a prefix as a variable, e.g., 'PROGRAMS',
+is an error.
+
+   Note that the common 'dir' suffix is left off when constructing the
+variable names; thus one writes 'bin_PROGRAMS' and not
+'bindir_PROGRAMS'.
+
+   Not every sort of object can be installed in every directory.
+Automake will flag those attempts it finds in error (but see below how
+to override the check if you really need to).  Automake will also
+diagnose obvious misspellings in directory names.
+
+   Sometimes the standard directories--even as augmented by
+Automake--are not enough.  In particular it is sometimes useful, for
+clarity, to install objects in a subdirectory of some predefined
+directory.  To this end, Automake allows you to extend the list of
+possible installation directories.  A given prefix (e.g., 'zar') is
+valid if a variable of the same name with 'dir' appended is defined
+(e.g., 'zardir').
+
+   For instance, the following snippet will install 'file.xml' into
+'$(datadir)/xml'.
+
+     xmldir = $(datadir)/xml
+     xml_DATA = file.xml
+
+   This feature can also be used to override the sanity checks Automake
+performs to diagnose suspicious directory/primary couples (in the
+unlikely case these checks are undesirable, and you really know what
+you're doing).  For example, Automake would error out on this input:
+
+     # Forbidden directory combinations, automake will error out on this.
+     pkglib_PROGRAMS = foo
+     doc_LIBRARIES = libquux.a
+
+but it will succeed with this:
+
+     # Work around forbidden directory combinations.  Do not use this
+     # without a very good reason!
+     my_execbindir = $(pkglibdir)
+     my_doclibdir = $(docdir)
+     my_execbin_PROGRAMS = foo
+     my_doclib_LIBRARIES = libquux.a
+
+   The 'exec' substring of the 'my_execbindir' variable lets the files
+be installed at the right time (*note The Two Parts of Install::).
+
+   The special prefix 'noinst_' indicates that the objects in question
+should be built but not installed at all.  This is usually used for
+objects required to build the rest of your package, for instance static
+libraries (*note A Library::), or helper scripts.
+
+   The special prefix 'check_' indicates that the objects in question
+should not be built until the 'make check' command is run.  Those
+objects are not installed either.
+
+   The current primary names are 'PROGRAMS', 'LIBRARIES', 'LTLIBRARIES',
+'LISP', 'PYTHON', 'JAVA', 'SCRIPTS', 'DATA', 'HEADERS', 'MANS', and
+'TEXINFOS'.
+
+   Some primaries also allow additional prefixes that control other
+aspects of 'automake''s behavior.  The currently defined prefixes are
+'dist_', 'nodist_', 'nobase_', and 'notrans_'.  These prefixes are
+explained later (*note Program and Library Variables::) (*note Man
+Pages::).
+

+File: automake.info,  Node: Length Limitations,  Next: Canonicalization,  Prev: Uniform,  Up: Generalities
+
+3.4 Staying below the command line length limit
+===============================================
+
+Traditionally, most unix-like systems have a length limitation for the
+command line arguments and environment contents when creating new
+processes (see for example
+<http://www.in-ulm.de/~mascheck/various/argmax/> for an overview on this
+issue), which of course also applies to commands spawned by 'make'.
+POSIX requires this limit to be at least 4096 bytes, and most modern
+systems have quite high limits (or are unlimited).
+
+   In order to create portable Makefiles that do not trip over these
+limits, it is necessary to keep the length of file lists bounded.
+Unfortunately, it is not possible to do so fully transparently within
+Automake, so your help may be needed.  Typically, you can split long
+file lists manually and use different installation directory names for
+each list.  For example,
+
+     data_DATA = file1 ... fileN fileN+1 ... file2N
+
+may also be written as
+
+     data_DATA = file1 ... fileN
+     data2dir = $(datadir)
+     data2_DATA = fileN+1 ... file2N
+
+and will cause Automake to treat the two lists separately during 'make
+install'.  See *note The Two Parts of Install:: for choosing directory
+names that will keep the ordering of the two parts of installation Note
+that 'make dist' may still only work on a host with a higher length
+limit in this example.
+
+   Automake itself employs a couple of strategies to avoid long command
+lines.  For example, when '${srcdir}/' is prepended to file names, as
+can happen with above '$(data_DATA)' lists, it limits the amount of
+arguments passed to external commands.
+
+   Unfortunately, some system's 'make' commands may prepend 'VPATH'
+prefixes like '${srcdir}/' to file names from the source tree
+automatically (*note Automatic Rule Rewriting: (autoconf)Automatic Rule
+Rewriting.).  In this case, the user may have to switch to use GNU Make,
+or refrain from using VPATH builds, in order to stay below the length
+limit.
+
+   For libraries and programs built from many sources, convenience
+archives may be used as intermediates in order to limit the object list
+length (*note Libtool Convenience Libraries::).

+
+3.5 How derived variables are named
+===================================
+
+Sometimes a Makefile variable name is derived from some text the
+maintainer supplies.  For instance, a program name listed in '_PROGRAMS'
+is rewritten into the name of a '_SOURCES' variable.  In cases like
+this, Automake canonicalizes the text, so that program names and the
+like do not have to follow Makefile variable naming rules.  All
+characters in the name except for letters, numbers, the strudel (@), and
+the underscore are turned into underscores when making variable
+references.
+
+   For example, if your program is named 'sniff-glue', the derived
+variable name would be 'sniff_glue_SOURCES', not 'sniff-glue_SOURCES'.
+Similarly the sources for a library named 'libmumble++.a' should be
+listed in the 'libmumble___a_SOURCES' variable.
+
+   The strudel is an addition, to make the use of Autoconf substitutions
+in variable names less obfuscating.
+
+
+File: automake.info,  Node: User Variables,  Next: Auxiliary Programs,  Prev: Canonicalization,  Up: Generalities
+
+3.6 Variables reserved for the user
+===================================
+
+Some 'Makefile' variables are reserved by the GNU Coding Standards for
+the use of the "user"--the person building the package.  For instance,
+'CFLAGS' is one such variable.
+
+   Sometimes package developers are tempted to set user variables such
+as 'CFLAGS' because it appears to make their job easier.  However, the
+package itself should never set a user variable, particularly not to
+include switches that are required for proper compilation of the
+package.  Since these variables are documented as being for the package
+builder, that person rightfully expects to be able to override any of
+these variables at build time.
+
+   To get around this problem, Automake introduces an automake-specific
+shadow variable for each user flag variable.  (Shadow variables are not
+introduced for variables like 'CC', where they would make no sense.)
+The shadow variable is named by prepending 'AM_' to the user variable's
+name.  For instance, the shadow variable for 'YFLAGS' is 'AM_YFLAGS'.
+The package maintainer--that is, the author(s) of the 'Makefile.am' and
+'configure.ac' files--may adjust these shadow variables however
+necessary.
+
+   *Note Flag Variables Ordering::, for more discussion about these
+variables and how they interact with per-target variables.
+
+
+File: automake.info,  Node: Auxiliary Programs,  Prev: User Variables,  Up: Generalities
+
+3.7 Programs automake might require
+===================================
+
+Automake sometimes requires helper programs so that the generated
+'Makefile' can do its work properly.  There are a fairly large number of
+them, and we list them here.
+
+   Although all of these files are distributed and installed with
+Automake, a couple of them are maintained separately.  The Automake
+copies are updated before each release, but we mention the original
+source in case you need more recent versions.
+
+'ar-lib'
+     This is a wrapper primarily for the Microsoft lib archiver, to make
+     it more POSIX-like.
+
+'compile'
+     This is a wrapper for compilers that do not accept options '-c' and
+     '-o' at the same time.  It is only used when absolutely required.
+     Such compilers are rare, with the Microsoft C/C++ Compiler as the
+     most notable exception.  This wrapper also makes the following
+     common options available for that compiler, while performing file
+     name translation where needed: '-I', '-L', '-l', '-Wl,' and
+     '-Xlinker'.
+
+'config.guess'
+'config.sub'
+     These two programs compute the canonical triplets for the given
+     build, host, or target architecture.  These programs are updated
+     regularly to support new architectures and fix probes broken by
+     changes in new kernel versions.  Each new release of Automake comes
+     with up-to-date copies of these programs.  If your copy of Automake
+     is getting old, you are encouraged to fetch the latest versions of
+     these files from <http://savannah.gnu.org/git/?group=config> before
+     making a release.
+
+'depcomp'
+     This program understands how to run a compiler so that it will
+     generate not only the desired output but also dependency
+     information that is then used by the automatic dependency tracking
+     feature (*note Dependencies::).
+
+'install-sh'
+     This is a replacement for the 'install' program that works on
+     platforms where 'install' is unavailable or unusable.
+
+'mdate-sh'
+     This script is used to generate a 'version.texi' file.  It examines
+     a file and prints some date information about it.
+
+'missing'
+     This wraps a number of programs that are typically only required by
+     maintainers.  If the program in question doesn't exist, or seems to
+     old, 'missing' will print an informative warning before failing
+     out, to provide the user with more context and information.
+
+'mkinstalldirs'
+     This script used to be a wrapper around 'mkdir -p', which is not
+     portable.  Now we prefer to use 'install-sh -d' when 'configure'
+     finds that 'mkdir -p' does not work, this makes one less script to
+     distribute.
+
+     For backward compatibility 'mkinstalldirs' is still used and
+     distributed when 'automake' finds it in a package.  But it is no
+     longer installed automatically, and it should be safe to remove it.
+
+'py-compile'
+     This is used to byte-compile Python scripts.
+
+'test-driver'
+     This implements the default test driver offered by the parallel
+     testsuite harness.
+
+'texinfo.tex'
+     Not a program, this file is required for 'make dvi', 'make ps' and
+     'make pdf' to work when Texinfo sources are in the package.  The
+     latest version can be downloaded from
+     <http://www.gnu.org/software/texinfo/>.
+
+'ylwrap'
+     This program wraps 'lex' and 'yacc' to rename their output files.
+     It also ensures that, for instance, multiple 'yacc' instances can
+     be invoked in a single directory in parallel.

+4 Some example packages
+***********************
+
+This section contains two small examples.
+
+   The first example (*note Complete::) assumes you have an existing
+project already using Autoconf, with handcrafted 'Makefile's, and that
+you want to convert it to using Automake.  If you are discovering both
+tools, it is probably better that you look at the Hello World example
+presented earlier (*note Hello World::).
+
+   The second example (*note true::) shows how two programs can be built
+from the same file, using different compilation parameters.  It contains
+some technical digressions that are probably best skipped on first read.
+
+* Menu:
+
+* Complete::                    A simple example, start to finish

+File: automake.info,  Node: Complete,  Next: true,  Up: Examples
+
+4.1 A simple example, start to finish
+=====================================
+
+Let's suppose you just finished writing 'zardoz', a program to make your
+head float from vortex to vortex.  You've been using Autoconf to provide
+a portability framework, but your 'Makefile.in's have been ad-hoc.  You
+want to make them bulletproof, so you turn to Automake.
+
+   The first step is to update your 'configure.ac' to include the
+commands that 'automake' needs.  The way to do this is to add an
+'AM_INIT_AUTOMAKE' call just after 'AC_INIT':
+
+     AC_INIT([zardoz], [1.0])
+     AM_INIT_AUTOMAKE
+     ...
+
+   Since your program doesn't have any complicating factors (e.g., it
+doesn't use 'gettext', it doesn't want to build a shared library),
+you're done with this part.  That was easy!
+
+   Now you must regenerate 'configure'.  But to do that, you'll need to
+tell 'autoconf' how to find the new macro you've used.  The easiest way
+to do this is to use the 'aclocal' program to generate your 'aclocal.m4'
+for you.  But wait... maybe you already have an 'aclocal.m4', because
+you had to write some hairy macros for your program.  The 'aclocal'
+program lets you put your own macros into 'acinclude.m4', so simply
+rename and then run:
+
+     mv aclocal.m4 acinclude.m4
+     aclocal
+     autoconf
+
+   Now it is time to write your 'Makefile.am' for 'zardoz'.  Since
+'zardoz' is a user program, you want to install it where the rest of the
+user programs go: 'bindir'.  Additionally, 'zardoz' has some Texinfo
+documentation.  Your 'configure.ac' script uses 'AC_REPLACE_FUNCS', so
+you need to link against '$(LIBOBJS)'.  So here's what you'd write:
+
+     bin_PROGRAMS = zardoz
+     zardoz_SOURCES = main.c head.c float.c vortex9.c gun.c
+     zardoz_LDADD = $(LIBOBJS)
+
+     info_TEXINFOS = zardoz.texi
+
+   Now you can run 'automake --add-missing' to generate your
+'Makefile.in' and grab any auxiliary files you might need, and you're
+done!
+

+File: automake.info,  Node: true,  Prev: Complete,  Up: Examples
+
+4.2 Building true and false
+===========================
+
+Here is another, trickier example.  It shows how to generate two
+programs ('true' and 'false') from the same source file ('true.c').  The
+difficult part is that each compilation of 'true.c' requires different
+'cpp' flags.
+
+     bin_PROGRAMS = true false
+     false_SOURCES =
+     false_LDADD = false.o
+
+     true.o: true.c
+             $(COMPILE) -DEXIT_CODE=0 -c true.c
+
+     false.o: true.c
+             $(COMPILE) -DEXIT_CODE=1 -o false.o -c true.c
+
+   Note that there is no 'true_SOURCES' definition.  Automake will
+implicitly assume that there is a source file named 'true.c' (*note
+Default _SOURCES::), and define rules to compile 'true.o' and link
+'true'.  The 'true.o: true.c' rule supplied by the above 'Makefile.am',
+will override the Automake generated rule to build 'true.o'.
+
+   'false_SOURCES' is defined to be empty--that way no implicit value is
+substituted.  Because we have not listed the source of 'false', we have
+to tell Automake how to link the program.  This is the purpose of the
+'false_LDADD' line.  A 'false_DEPENDENCIES' variable, holding the
+dependencies of the 'false' target will be automatically generated by
+Automake from the content of 'false_LDADD'.
+
+   The above rules won't work if your compiler doesn't accept both '-c'
+and '-o'.  The simplest fix for this is to introduce a bogus dependency
+(to avoid problems with a parallel 'make'):
+
+     true.o: true.c false.o
+             $(COMPILE) -DEXIT_CODE=0 -c true.c
+
+     false.o: true.c
+             $(COMPILE) -DEXIT_CODE=1 -c true.c && mv true.o false.o
+
+   As it turns out, there is also a much easier way to do this same
+task.  Some of the above technique is useful enough that we've kept the
+example in the manual.  However if you were to build 'true' and 'false'
+in real life, you would probably use per-program compilation flags, like
+so:
+
+     bin_PROGRAMS = false true
+
+     false_SOURCES = true.c
+     false_CPPFLAGS = -DEXIT_CODE=1
+
+     true_SOURCES = true.c
+     true_CPPFLAGS = -DEXIT_CODE=0
+
+   In this case Automake will cause 'true.c' to be compiled twice, with
+different flags.  In this instance, the names of the object files would
+be chosen by automake; they would be 'false-true.o' and 'true-true.o'.
+(The name of the object files rarely matters.)

+
+5 Creating a 'Makefile.in'
+**************************
+
+To create all the 'Makefile.in's for a package, run the 'automake'
+program in the top level directory, with no arguments.  'automake' will
+automatically find each appropriate 'Makefile.am' (by scanning
+'configure.ac'; *note configure::) and generate the corresponding
+'Makefile.in'.  Note that 'automake' has a rather simplistic view of
+what constitutes a package; it assumes that a package has only one
+'configure.ac', at the top.  If your package has multiple
+'configure.ac's, then you must run 'automake' in each directory holding
+a 'configure.ac'.  (Alternatively, you may rely on Autoconf's
+'autoreconf', which is able to recurse your package tree and run
+'automake' where appropriate.)
+
+   You can optionally give 'automake' an argument; '.am' is appended to
+the argument and the result is used as the name of the input file.  This
+feature is generally only used to automatically rebuild an out-of-date
+'Makefile.in'.  Note that 'automake' must always be run from the topmost
+directory of a project, even if being used to regenerate the
+'Makefile.in' in some subdirectory.  This is necessary because
+'automake' must scan 'configure.ac', and because 'automake' uses the
+knowledge that a 'Makefile.in' is in a subdirectory to change its
+behavior in some cases.
+
+   Automake will run 'autoconf' to scan 'configure.ac' and its
+dependencies (i.e., 'aclocal.m4' and any included file), therefore
+'autoconf' must be in your 'PATH'.  If there is an 'AUTOCONF' variable
+in your environment it will be used instead of 'autoconf', this allows
+you to select a particular version of Autoconf.  By the way, don't
+misunderstand this paragraph: 'automake' runs 'autoconf' to *scan* your
+'configure.ac', this won't build 'configure' and you still have to run
+'autoconf' yourself for this purpose.
+
+   'automake' accepts the following options:
+
+'-a'
+'--add-missing'
+     Automake requires certain common files to exist in certain
+     situations; for instance, 'config.guess' is required if
+     'configure.ac' invokes 'AC_CANONICAL_HOST'.  Automake is
+     distributed with several of these files (*note Auxiliary
+     Programs::); this option will cause the missing ones to be
+     automatically added to the package, whenever possible.  In general
+     if Automake tells you a file is missing, try using this option.  By
+     default Automake tries to make a symbolic link pointing to its own
+     copy of the missing file; this can be changed with '--copy'.
+
+     Many of the potentially-missing files are common scripts whose
+     location may be specified via the 'AC_CONFIG_AUX_DIR' macro.
+     Therefore, 'AC_CONFIG_AUX_DIR''s setting affects whether a file is
+     considered missing, and where the missing file is added (*note
+     Optional::).
+
+     In some strictness modes, additional files are installed, see *note
+     Gnits:: for more information.
+
+'--libdir=DIR'
+     Look for Automake data files in directory DIR instead of in the
+     installation directory.  This is typically used for debugging.
+
+'--print-libdir'
+     Print the path of the installation directory containing
+     Automake-provided scripts and data files (like e.g., 'texinfo.texi'
+     and 'install-sh').
+
+'-c'
+'--copy'
+     When used with '--add-missing', causes installed files to be
+     copied.  The default is to make a symbolic link.
+
+'-f'
+'--force-missing'
+     When used with '--add-missing', causes standard files to be
+     reinstalled even if they already exist in the source tree.  This
+     involves removing the file from the source tree before creating the
+     new symlink (or, with '--copy', copying the new file).
+
+'--foreign'
+     Set the global strictness to 'foreign'.  For more information, see
+     *note Strictness::.
+
+'--gnits'
+     Set the global strictness to 'gnits'.  For more information, see
+     *note Gnits::.
+
+'--gnu'
+     Set the global strictness to 'gnu'.  For more information, see
+     *note Gnits::.  This is the default strictness.
+
+'--help'
+     Print a summary of the command line options and exit.
+
+'-i'
+'--ignore-deps'
+     This disables the dependency tracking feature in generated
+     'Makefile's; see *note Dependencies::.
+
+'--include-deps'
+     This enables the dependency tracking feature.  This feature is
+     enabled by default.  This option is provided for historical reasons
+     only and probably should not be used.
+
+'--no-force'
+     Ordinarily 'automake' creates all 'Makefile.in's mentioned in
+     'configure.ac'.  This option causes it to only update those
+     'Makefile.in's that are out of date with respect to one of their
+     dependents.
+
+'-o DIR'
+'--output-dir=DIR'
+     Put the generated 'Makefile.in' in the directory DIR.  Ordinarily
+     each 'Makefile.in' is created in the directory of the corresponding
+     'Makefile.am'.  This option is deprecated and will be removed in a
+     future release.
+
+'-v'
+'--verbose'
+     Cause Automake to print information about which files are being
+     read or created.
+
+'--version'
+     Print the version number of Automake and exit.
+
+'-W CATEGORY'
+'--warnings=CATEGORY'
+     Output warnings falling in CATEGORY.  CATEGORY can be one of:
+     'gnu'
+          warnings related to the GNU Coding Standards (*note
+          (standards)Top::).
+     'obsolete'
+          obsolete features or constructions
+     'override'
+          user redefinitions of Automake rules or variables
+     'portability'
+          portability issues (e.g., use of 'make' features that are
+          known to be not portable)
+     'extra-portability'
+          extra portability issues related to obscure tools.  One
+          example of such a tool is the Microsoft 'lib' archiver.
+     'syntax'
+          weird syntax, unused variables, typos
+     'unsupported'
+          unsupported or incomplete features
+     'all'
+          all the warnings
+     'none'
+          turn off all the warnings
+     'error'
+          treat warnings as errors
+
+     A category can be turned off by prefixing its name with 'no-'.  For
+     instance, '-Wno-syntax' will hide the warnings about unused
+     variables.
+
+     The categories output by default are 'obsolete', 'syntax' and
+     'unsupported'.  Additionally, 'gnu' and 'portability' are enabled
+     in '--gnu' and '--gnits' strictness.
+
+     Turning off 'portability' will also turn off 'extra-portability',
+     and similarly turning on 'extra-portability' will also turn on
+     'portability'.  However, turning on 'portability' or turning off
+     'extra-portability' will not affect the other category.
+
+     The environment variable 'WARNINGS' can contain a comma separated
+     list of categories to enable.  It will be taken into account before
+     the command-line switches, this way '-Wnone' will also ignore any
+     warning category enabled by 'WARNINGS'.  This variable is also used
+     by other tools like 'autoconf'; unknown categories are ignored for
+     this reason.
+
+   If the environment variable 'AUTOMAKE_JOBS' contains a positive
+number, it is taken as the maximum number of Perl threads to use in
+'automake' for generating multiple 'Makefile.in' files concurrently.
+This is an experimental feature.

+6 Scanning 'configure.ac', using 'aclocal'
+******************************************
+
+Automake scans the package's 'configure.ac' to determine certain
+information about the package.  Some 'autoconf' macros are required and
+some variables must be defined in 'configure.ac'.  Automake will also
+use information from 'configure.ac' to further tailor its output.
+
+   Automake also supplies some Autoconf macros to make the maintenance
+easier.  These macros can automatically be put into your 'aclocal.m4'
+using the 'aclocal' program.

+
+File: automake.info,  Node: Requirements,  Next: Optional,  Up: configure
+
+6.1 Configuration requirements
+==============================
+
+The one real requirement of Automake is that your 'configure.ac' call
+'AM_INIT_AUTOMAKE'.  This macro does several things that are required
+for proper Automake operation (*note Macros::).
+
+   Here are the other macros that Automake requires but which are not
+run by 'AM_INIT_AUTOMAKE':
+
+'AC_CONFIG_FILES'
+'AC_OUTPUT'
+     These two macros are usually invoked as follows near the end of
+     'configure.ac'.
+
+          ...
+          AC_CONFIG_FILES([
+            Makefile
+            doc/Makefile
+            src/Makefile
+            src/lib/Makefile
+            ...
+          ])
+          AC_OUTPUT
+
+     Automake uses these to determine which files to create (*note
+     Creating Output Files: (autoconf)Output.).  A listed file is
+     considered to be an Automake generated 'Makefile' if there exists a
+     file with the same name and the '.am' extension appended.
+     Typically, 'AC_CONFIG_FILES([foo/Makefile])' will cause Automake to
+     generate 'foo/Makefile.in' if 'foo/Makefile.am' exists.
+
+     When using 'AC_CONFIG_FILES' with multiple input files, as in
+
+          AC_CONFIG_FILES([Makefile:top.in:Makefile.in:bot.in])
+
+     'automake' will generate the first '.in' input file for which a
+     '.am' file exists.  If no such file exists the output file is not
+     considered to be generated by Automake.
+
+     Files created by 'AC_CONFIG_FILES', be they Automake 'Makefile's or
+     not, are all removed by 'make distclean'.  Their inputs are
+     automatically distributed, unless they are the output of prior
+     'AC_CONFIG_FILES' commands.  Finally, rebuild rules are generated
+     in the Automake 'Makefile' existing in the subdirectory of the
+     output file, if there is one, or in the top-level 'Makefile'
+     otherwise.
+
+     The above machinery (cleaning, distributing, and rebuilding) works
+     fine if the 'AC_CONFIG_FILES' specifications contain only literals.
+     If part of the specification uses shell variables, 'automake' will
+     not be able to fulfill this setup, and you will have to complete
+     the missing bits by hand.  For instance, on
+
+          file=input
+          ...
+          AC_CONFIG_FILES([output:$file],, [file=$file])
+
+     'automake' will output rules to clean 'output', and rebuild it.
+     However the rebuild rule will not depend on 'input', and this file
+     will not be distributed either.  (You must add 'EXTRA_DIST = input'
+     to your 'Makefile.am' if 'input' is a source file.)
+
+     Similarly
+
+          file=output
+          file2=out:in
+          ...
+          AC_CONFIG_FILES([$file:input],, [file=$file])
+          AC_CONFIG_FILES([$file2],, [file2=$file2])
+
+     will only cause 'input' to be distributed.  No file will be cleaned
+     automatically (add 'DISTCLEANFILES = output out' yourself), and no
+     rebuild rule will be output.
+
+     Obviously 'automake' cannot guess what value '$file' is going to
+     hold later when 'configure' is run, and it cannot use the shell
+     variable '$file' in a 'Makefile'.  However, if you make reference
+     to '$file' as '${file}' (i.e., in a way that is compatible with
+     'make''s syntax) and furthermore use 'AC_SUBST' to ensure that
+     '${file}' is meaningful in a 'Makefile', then 'automake' will be
+     able to use '${file}' to generate all of these rules.  For
+     instance, here is how the Automake package itself generates
+     versioned scripts for its test suite:
+
+          AC_SUBST([APIVERSION], ...)
+          ...
+          AC_CONFIG_FILES(
+            [tests/aclocal-${APIVERSION}:tests/aclocal.in],
+            [chmod +x tests/aclocal-${APIVERSION}],
+            [APIVERSION=$APIVERSION])
+          AC_CONFIG_FILES(
+            [tests/automake-${APIVERSION}:tests/automake.in],
+            [chmod +x tests/automake-${APIVERSION}])
+
+     Here cleaning, distributing, and rebuilding are done automatically,
+     because '${APIVERSION}' is known at 'make'-time.
+
+     Note that you should not use shell variables to declare 'Makefile'
+     files for which 'automake' must create 'Makefile.in'.  Even
+     'AC_SUBST' does not help here, because 'automake' needs to know the
+     file name when it runs in order to check whether 'Makefile.am'
+     exists.  (In the very hairy case that your setup requires such use
+     of variables, you will have to tell Automake which 'Makefile.in's
+     to generate on the command-line.)
+
+     It is possible to let 'automake' emit conditional rules for
+     'AC_CONFIG_FILES' with the help of 'AM_COND_IF' (*note Optional::).
+
+     To summarize:
+        * Use literals for 'Makefile's, and for other files whenever
+          possible.
+        * Use '$file' (or '${file}' without 'AC_SUBST([file])') for
+          files that 'automake' should ignore.
+        * Use '${file}' and 'AC_SUBST([file])' for files that 'automake'
+          should not ignore.

+
+6.2 Other things Automake recognizes
+====================================
+
+Every time Automake is run it calls Autoconf to trace 'configure.ac'.
+This way it can recognize the use of certain macros and tailor the
+generated 'Makefile.in' appropriately.  Currently recognized macros and
+their effects are:
+
+'AC_CANONICAL_BUILD'
+'AC_CANONICAL_HOST'
+'AC_CANONICAL_TARGET'
+     Automake will ensure that 'config.guess' and 'config.sub' exist.
+     Also, the 'Makefile' variables 'build_triplet', 'host_triplet' and
+     'target_triplet' are introduced.  See *note Getting the Canonical
+     System Type: (autoconf)Canonicalizing.
+
+'AC_CONFIG_AUX_DIR'
+     Automake will look for various helper scripts, such as
+     'install-sh', in the directory named in this macro invocation.
+     (The full list of scripts is: 'ar-lib', 'config.guess',
+     'config.sub', 'depcomp', 'compile', 'install-sh', 'ltmain.sh',
+     'mdate-sh', 'missing', 'mkinstalldirs', 'py-compile',
+     'test-driver', 'texinfo.tex', 'ylwrap'.)  Not all scripts are
+     always searched for; some scripts will only be sought if the
+     generated 'Makefile.in' requires them.
+
+     If 'AC_CONFIG_AUX_DIR' is not given, the scripts are looked for in
+     their standard locations.  For 'mdate-sh', 'texinfo.tex', and
+     'ylwrap', the standard location is the source directory
+     corresponding to the current 'Makefile.am'.  For the rest, the
+     standard location is the first one of '.', '..', or '../..'
+     (relative to the top source directory) that provides any one of the
+     helper scripts.  *Note Finding 'configure' Input: (autoconf)Input.
+
+     Required files from 'AC_CONFIG_AUX_DIR' are automatically
+     distributed, even if there is no 'Makefile.am' in this directory.
+
+'AC_CONFIG_LIBOBJ_DIR'
+     Automake will require the sources file declared with 'AC_LIBSOURCE'
+     (see below) in the directory specified by this macro.
+
+'AC_CONFIG_HEADERS'
+     Automake will generate rules to rebuild these headers from the
+     corresponding templates (usually, the template for a 'foo.h' header
+     being 'foo.h.in').  Older versions of Automake required the use of
+     'AM_CONFIG_HEADER'; this is no longer the case, and that macro has
+     indeed been removed.
+
+     As with 'AC_CONFIG_FILES' (*note Requirements::), parts of the
+     specification using shell variables will be ignored as far as
+     cleaning, distributing, and rebuilding is concerned.
+
+'AC_CONFIG_LINKS'
+     Automake will generate rules to remove 'configure' generated links
+     on 'make distclean' and to distribute named source files as part of
+     'make dist'.
+
+     As for 'AC_CONFIG_FILES' (*note Requirements::), parts of the
+     specification using shell variables will be ignored as far as
+     cleaning and distributing is concerned.  (There are no rebuild
+     rules for links.)
+
+'AC_LIBOBJ'
+'AC_LIBSOURCE'
+'AC_LIBSOURCES'
+     Automake will automatically distribute any file listed in
+     'AC_LIBSOURCE' or 'AC_LIBSOURCES'.
+
+     Note that the 'AC_LIBOBJ' macro calls 'AC_LIBSOURCE'.  So if an
+     Autoconf macro is documented to call 'AC_LIBOBJ([file])', then
+     'file.c' will be distributed automatically by Automake.  This
+     encompasses many macros like 'AC_FUNC_ALLOCA', 'AC_FUNC_MEMCMP',
+     'AC_REPLACE_FUNCS', and others.
+
+     By the way, direct assignments to 'LIBOBJS' are no longer
+     supported.  You should always use 'AC_LIBOBJ' for this purpose.
+     *Note 'AC_LIBOBJ' vs. 'LIBOBJS': (autoconf)AC_LIBOBJ vs LIBOBJS.
+
+'AC_PROG_RANLIB'
+     This is required if any libraries are built in the package.  *Note
+     Particular Program Checks: (autoconf)Particular Programs.
+
+'AC_PROG_CXX'
+     This is required if any C++ source is included.  *Note Particular
+     Program Checks: (autoconf)Particular Programs.
+
+'AC_PROG_OBJC'
+     This is required if any Objective C source is included.  *Note
+     Particular Program Checks: (autoconf)Particular Programs.
+
+'AC_PROG_OBJCXX'
+     This is required if any Objective C++ source is included.  *Note
+     Particular Program Checks: (autoconf)Particular Programs.
+
+'AC_PROG_F77'
+     This is required if any Fortran 77 source is included.  *Note
+     Particular Program Checks: (autoconf)Particular Programs.
+
+'AC_F77_LIBRARY_LDFLAGS'
+     This is required for programs and shared libraries that are a
+     mixture of languages that include Fortran 77 (*note Mixing Fortran
+     77 With C and C++::).  *Note Autoconf macros supplied with
+     Automake: Macros.
+
+'AC_FC_SRCEXT'
+     Automake will add the flags computed by 'AC_FC_SRCEXT' to
+     compilation of files with the respective source extension (*note
+     Fortran Compiler Characteristics: (autoconf)Fortran Compiler.).
+
+'AC_PROG_FC'
+     This is required if any Fortran 90/95 source is included.  This
+     macro is distributed with Autoconf version 2.58 and later.  *Note
+     Particular Program Checks: (autoconf)Particular Programs.
+
+'AC_PROG_LIBTOOL'
+     Automake will turn on processing for 'libtool' (*note Introduction:
+     (libtool)Top.).
+
+'AC_PROG_YACC'
+     If a Yacc source file is seen, then you must either use this macro
+     or define the variable 'YACC' in 'configure.ac'.  The former is
+     preferred (*note Particular Program Checks: (autoconf)Particular
+     Programs.).
+
+'AC_PROG_LEX'
+     If a Lex source file is seen, then this macro must be used.  *Note
+     Particular Program Checks: (autoconf)Particular Programs.
+
+'AC_REQUIRE_AUX_FILE'
+     For each 'AC_REQUIRE_AUX_FILE([FILE])', 'automake' will ensure that
+     'FILE' exists in the aux directory, and will complain otherwise.
+     It will also automatically distribute the file.  This macro should
+     be used by third-party Autoconf macros that require some supporting
+     files in the aux directory specified with 'AC_CONFIG_AUX_DIR'
+     above.  *Note Finding 'configure' Input: (autoconf)Input.
+
+'AC_SUBST'
+     The first argument is automatically defined as a variable in each
+     generated 'Makefile.in', unless 'AM_SUBST_NOTMAKE' is also used for
+     this variable.  *Note Setting Output Variables: (autoconf)Setting
+     Output Variables.
+
+     For every substituted variable VAR, 'automake' will add a line 'VAR
+     = VALUE' to each 'Makefile.in' file.  Many Autoconf macros invoke
+     'AC_SUBST' to set output variables this way, e.g., 'AC_PATH_XTRA'
+     defines 'X_CFLAGS' and 'X_LIBS'.  Thus, you can access these
+     variables as '$(X_CFLAGS)' and '$(X_LIBS)' in any 'Makefile.am' if
+     'AC_PATH_XTRA' is called.
+
+'AM_CONDITIONAL'
+     This introduces an Automake conditional (*note Conditionals::).
+
+'AM_COND_IF'
+     This macro allows 'automake' to detect subsequent access within
+     'configure.ac' to a conditional previously introduced with
+     'AM_CONDITIONAL', thus enabling conditional 'AC_CONFIG_FILES'
+     (*note Usage of Conditionals::).
+
+'AM_GNU_GETTEXT'
+     This macro is required for packages that use GNU gettext (*note
+     gettext::).  It is distributed with gettext.  If Automake sees this
+     macro it ensures that the package meets some of gettext's
+     requirements.
+
+'AM_GNU_GETTEXT_INTL_SUBDIR'
+     This macro specifies that the 'intl/' subdirectory is to be built,
+     even if the 'AM_GNU_GETTEXT' macro was invoked with a first
+     argument of 'external'.
+
+'AM_MAINTAINER_MODE([DEFAULT-MODE])'
+     This macro adds an '--enable-maintainer-mode' option to
+     'configure'.  If this is used, 'automake' will cause
+     "maintainer-only" rules to be turned off by default in the
+     generated 'Makefile.in's, unless DEFAULT-MODE is 'enable'.  This
+     macro defines the 'MAINTAINER_MODE' conditional, which you can use
+     in your own 'Makefile.am'.  *Note maintainer-mode::.
+
+'AM_SUBST_NOTMAKE(VAR)'
+     Prevent Automake from defining a variable VAR, even if it is
+     substituted by 'config.status'.  Normally, Automake defines a
+     'make' variable for each 'configure' substitution, i.e., for each
+     'AC_SUBST([VAR])'.  This macro prevents that definition from
+     Automake.  If 'AC_SUBST' has not been called for this variable,
+     then 'AM_SUBST_NOTMAKE' has no effects.  Preventing variable
+     definitions may be useful for substitution of multi-line values,
+     where 'VAR = @VALUE@' might yield unintended results.
+
+'m4_include'
+     Files included by 'configure.ac' using this macro will be detected
+     by Automake and automatically distributed.  They will also appear
+     as dependencies in 'Makefile' rules.
+
+     'm4_include' is seldom used by 'configure.ac' authors, but can
+     appear in 'aclocal.m4' when 'aclocal' detects that some required
+     macros come from files local to your package (as opposed to macros
+     installed in a system-wide directory, *note aclocal Invocation::).

+
+6.3 Auto-generating aclocal.m4
+==============================
+
+Automake includes a number of Autoconf macros that can be used in your
+package (*note Macros::); some of them are actually required by Automake
+in certain situations.  These macros must be defined in your
+'aclocal.m4'; otherwise they will not be seen by 'autoconf'.
+
+   The 'aclocal' program will automatically generate 'aclocal.m4' files
+based on the contents of 'configure.ac'.  This provides a convenient way
+to get Automake-provided macros, without having to search around.  The
+'aclocal' mechanism allows other packages to supply their own macros
+(*note Extending aclocal::).  You can also use it to maintain your own
+set of custom macros (*note Local Macros::).
+
+   At startup, 'aclocal' scans all the '.m4' files it can find, looking
+for macro definitions (*note Macro Search Path::).  Then it scans
+'configure.ac'.  Any mention of one of the macros found in the first
+step causes that macro, and any macros it in turn requires, to be put
+into 'aclocal.m4'.
+
+   _Putting_ the file that contains the macro definition into
+'aclocal.m4' is usually done by copying the entire text of this file,
+including unused macro definitions as well as both '#' and 'dnl'
+comments.  If you want to make a comment that will be completely ignored
+by 'aclocal', use '##' as the comment leader.
+
+   When a file selected by 'aclocal' is located in a subdirectory
+specified as a relative search path with 'aclocal''s '-I' argument,
+'aclocal' assumes the file belongs to the package and uses 'm4_include'
+instead of copying it into 'aclocal.m4'.  This makes the package
+smaller, eases dependency tracking, and cause the file to be distributed
+automatically.  (*Note Local Macros::, for an example.)  Any macro that
+is found in a system-wide directory, or via an absolute search path will
+be copied.  So use '-I `pwd`/reldir' instead of '-I reldir' whenever
+some relative directory should be considered outside the package.
+
+   The contents of 'acinclude.m4', if this file exists, are also
+automatically included in 'aclocal.m4'.  We recommend against using
+'acinclude.m4' in new packages (*note Local Macros::).
+
+   While computing 'aclocal.m4', 'aclocal' runs 'autom4te' (*note Using
+'Autom4te': (autoconf)Using autom4te.) in order to trace the macros that
+are really used, and omit from 'aclocal.m4' all macros that are
+mentioned but otherwise unexpanded (this can happen when a macro is
+called conditionally).  'autom4te' is expected to be in the 'PATH', just
+as 'autoconf'.  Its location can be overridden using the 'AUTOM4TE'
+environment variable.

+
+6.3.1 aclocal Options
+---------------------
+
+'aclocal' accepts the following options:
+
+'--automake-acdir=DIR'
+     Look for the automake-provided macro files in DIR instead of in the
+     installation directory.  This is typically used for debugging.
+
+'--system-acdir=DIR'
+     Look for the system-wide third-party macro files (and the special
+     'dirlist' file) in DIR instead of in the installation directory.
+     This is typically used for debugging.
+
+'--diff[=COMMAND]'
+     Run COMMAND on M4 file that would be installed or overwritten by
+     '--install'.  The default COMMAND is 'diff -u'.  This option
+     implies '--install' and '--dry-run'.
+
+'--dry-run'
+     Do not actually overwrite (or create) 'aclocal.m4' and M4 files
+     installed by '--install'.
+
+'--help'
+     Print a summary of the command line options and exit.
+
+'-I DIR'
+     Add the directory DIR to the list of directories searched for '.m4'
+     files.
+
+'--install'
+     Install system-wide third-party macros into the first directory
+     specified with '-I DIR' instead of copying them in the output file.
+     Note that this will happen also if DIR is an absolute path.
+
+     When this option is used, and only when this option is used,
+     'aclocal' will also honor '#serial NUMBER' lines that appear in
+     macros: an M4 file is ignored if there exists another M4 file with
+     the same basename and a greater serial number in the search path
+     (*note Serials::).
+
+'--force'
+     Always overwrite the output file.  The default is to overwrite the
+     output file only when really needed, i.e., when its contents
+     changes or if one of its dependencies is younger.
+
+     This option forces the update of 'aclocal.m4' (or the file
+     specified with '--output' below) and only this file, it has
+     absolutely no influence on files that may need to be installed by
+     '--install'.
+
+'--output=FILE'
+     Cause the output to be put into FILE instead of 'aclocal.m4'.
+
+'--print-ac-dir'
+     Prints the name of the directory that 'aclocal' will search to find
+     third-party '.m4' files.  When this option is given, normal
+     processing is suppressed.  This option was used _in the past_ by
+     third-party packages to determine where to install '.m4' macro
+     files, but _this usage is today discouraged_, since it causes
+     '$(prefix)' not to be thoroughly honoured (which violates the GNU
+     Coding Standards), and a similar semantics can be better obtained
+     with the 'ACLOCAL_PATH' environment variable; *note Extending
+     aclocal::.
+
+'--verbose'
+     Print the names of the files it examines.
+
+'--version'
+     Print the version number of Automake and exit.
+
+'-W CATEGORY'
+'--warnings=CATEGORY'
+     Output warnings falling in CATEGORY.  CATEGORY can be one of:
+     'syntax'
+          dubious syntactic constructs, underquoted macros, unused
+          macros, etc.
+     'unsupported'
+          unknown macros
+     'all'
+          all the warnings, this is the default
+     'none'
+          turn off all the warnings
+     'error'
+          treat warnings as errors
+
+     All warnings are output by default.
+
+     The environment variable 'WARNINGS' is honored in the same way as
+     it is for 'automake' (*note automake Invocation::).

+File: automake.info,  Node: Macro Search Path,  Next: Extending aclocal,  Prev: aclocal Options,  Up: aclocal Invocation
+
+6.3.2 Macro Search Path
+-----------------------
+
+By default, 'aclocal' searches for '.m4' files in the following
+directories, in this order:
+
+'ACDIR-APIVERSION'
+     This is where the '.m4' macros distributed with Automake itself are
+     stored.  APIVERSION depends on the Automake release used; for
+     example, for Automake 1.11.x, APIVERSION = '1.11'.
+
+'ACDIR'
+     This directory is intended for third party '.m4' files, and is
+     configured when 'automake' itself is built.  This is
+     '@datadir@/aclocal/', which typically expands to
+     '${prefix}/share/aclocal/'.  To find the compiled-in value of
+     ACDIR, use the '--print-ac-dir' option (*note aclocal Options::).
+
+   As an example, suppose that 'automake-1.11.2' was configured with
+'--prefix=/usr/local'.  Then, the search path would be:
+
+  1. '/usr/local/share/aclocal-1.11.2/'
+  2. '/usr/local/share/aclocal/'
+
+   The paths for the ACDIR and ACDIR-APIVERSION directories can be
+changed respectively through aclocal options '--system-acdir' and
+'--automake-acdir' (*note aclocal Options::).  Note however that these
+options are only intended for use by the internal Automake test suite,
+or for debugging under highly unusual situations; they are not
+ordinarily needed by end-users.
+
+   As explained in (*note aclocal Options::), there are several options
+that can be used to change or extend this search path.
+
+Modifying the Macro Search Path: '-I DIR'
+.........................................
+
+Any extra directories specified using '-I' options (*note aclocal
+Options::) are _prepended_ to this search list.  Thus, 'aclocal -I /foo
+-I /bar' results in the following search path:
+
+  1. '/foo'
+  2. '/bar'
+  3. ACDIR-APIVERSION
+  4. ACDIR
+
+Modifying the Macro Search Path: 'dirlist'
+..........................................
+
+There is a third mechanism for customizing the search path.  If a
+'dirlist' file exists in ACDIR, then that file is assumed to contain a
+list of directory patterns, one per line.  'aclocal' expands these
+patterns to directory names, and adds them to the search list _after_
+all other directories.  'dirlist' entries may use shell wildcards such
+as '*', '?', or '[...]'.
+
+   For example, suppose 'ACDIR/dirlist' contains the following:
+
+     /test1
+     /test2
+     /test3*
+
+and that 'aclocal' was called with the '-I /foo -I /bar' options.  Then,
+the search path would be
+
+  1. '/foo'
+  2. '/bar'
+  3. ACDIR-APIVERSION
+  4. ACDIR
+  5. '/test1'
+  6. '/test2'
+
+and all directories with path names starting with '/test3'.
+
+   If the '--system-acdir=DIR' option is used, then 'aclocal' will
+search for the 'dirlist' file in DIR; but remember the warnings above
+against the use of '--system-acdir'.
+
+   'dirlist' is useful in the following situation: suppose that
+'automake' version '1.11.2' is installed with '--prefix=/usr' by the
+system vendor.  Thus, the default search directories are
+
+  1. '/usr/share/aclocal-1.11/'
+  2. '/usr/share/aclocal/'
+
+   However, suppose further that many packages have been manually
+installed on the system, with $prefix=/usr/local, as is typical.  In
+that case, many of these "extra" '.m4' files are in
+'/usr/local/share/aclocal'.  The only way to force '/usr/bin/aclocal' to
+find these "extra" '.m4' files is to always call 'aclocal -I
+/usr/local/share/aclocal'.  This is inconvenient.  With 'dirlist', one
+may create a file '/usr/share/aclocal/dirlist' containing only the
+single line
+
+     /usr/local/share/aclocal
+
+   Now, the "default" search path on the affected system is
+
+  1. '/usr/share/aclocal-1.11/'
+  2. '/usr/share/aclocal/'
+  3. '/usr/local/share/aclocal/'
+
+   without the need for '-I' options; '-I' options can be reserved for
+project-specific needs ('my-source-dir/m4/'), rather than using it to
+work around local system-dependent tool installation directories.
+
+   Similarly, 'dirlist' can be handy if you have installed a local copy
+of Automake in your account and want 'aclocal' to look for macros
+installed at other places on the system.
+
+Modifying the Macro Search Path: 'ACLOCAL_PATH'
+...............................................
+
+The fourth and last mechanism to customize the macro search path is also
+the simplest.  Any directory included in the colon-separated environment
+variable 'ACLOCAL_PATH' is added to the search path and takes precedence
+over system directories (including those found via 'dirlist'), with the
+exception of the versioned directory ACDIR-APIVERSION (*note Macro
+Search Path::).  However, directories passed via '-I' will take
+precedence over directories in 'ACLOCAL_PATH'.
+
+   Also note that, if the '--install' option is used, any '.m4' file
+containing a required macro that is found in a directory listed in
+'ACLOCAL_PATH' will be installed locally.  In this case, serial numbers
+in '.m4' are honoured too, *note Serials::.
+
+   Conversely to 'dirlist', 'ACLOCAL_PATH' is useful if you are using a
+global copy of Automake and want 'aclocal' to look for macros somewhere
+under your home directory.
+
+Planned future incompatibilities
+................................
+
+The order in which the directories in the macro search path are
+currently looked up is confusing and/or suboptimal in various aspects,
+and is probably going to be changed in the future Automake release.  In
+particular, directories in 'ACLOCAL_PATH' and 'ACDIR' might end up
+taking precedence over 'ACDIR-APIVERSION', and directories in
+'ACDIR/dirlist' might end up taking precedence over 'ACDIR'.  _This is a
+possible future incompatibility!_

+
+6.3.3 Writing your own aclocal macros
+-------------------------------------
+
+The 'aclocal' program doesn't have any built-in knowledge of any macros,
+so it is easy to extend it with your own macros.
+
+   This can be used by libraries that want to supply their own Autoconf
+macros for use by other programs.  For instance, the 'gettext' library
+supplies a macro 'AM_GNU_GETTEXT' that should be used by any package
+using 'gettext'.  When the library is installed, it installs this macro
+so that 'aclocal' will find it.
+
+   A macro file's name should end in '.m4'.  Such files should be
+installed in '$(datadir)/aclocal'.  This is as simple as writing:
+
+     aclocaldir = $(datadir)/aclocal
+     aclocal_DATA = mymacro.m4 myothermacro.m4
+
+Please do use '$(datadir)/aclocal', and not something based on the
+result of 'aclocal --print-ac-dir' (*note Hard-Coded Install Paths::,
+for arguments).  It might also be helpful to suggest to the user to add
+the '$(datadir)/aclocal' directory to his 'ACLOCAL_PATH' variable (*note
+ACLOCAL_PATH::) so that 'aclocal' will find the '.m4' files installed by
+your package automatically.
+
+   A file of macros should be a series of properly quoted 'AC_DEFUN''s
+(*note (autoconf)Macro Definitions::).  The 'aclocal' programs also
+understands 'AC_REQUIRE' (*note (autoconf)Prerequisite Macros::), so it
+is safe to put each macro in a separate file.  Each file should have no
+side effects but macro definitions.  Especially, any call to 'AC_PREREQ'
+should be done inside the defined macro, not at the beginning of the
+file.
+
+   Starting with Automake 1.8, 'aclocal' will warn about all underquoted
+calls to 'AC_DEFUN'.  We realize this will annoy a lot of people,
+because 'aclocal' was not so strict in the past and many third party
+macros are underquoted; and we have to apologize for this temporary
+inconvenience.  The reason we have to be stricter is that a future
+implementation of 'aclocal' (*note Future of aclocal::) will have to
+temporarily include all of these third party '.m4' files, maybe several
+times, including even files that are not actually needed.  Doing so
+should alleviate many problems of the current implementation, however it
+requires a stricter style from the macro authors.  Hopefully it is easy
+to revise the existing macros.  For instance,
+
+     # bad style
+     AC_PREREQ(2.68)
+     AC_DEFUN(AX_FOOBAR,
+     [AC_REQUIRE([AX_SOMETHING])dnl
+     AX_FOO
+     AX_BAR
+     ])
+
+should be rewritten as
+
+     AC_DEFUN([AX_FOOBAR],
+     [AC_PREREQ([2.68])dnl
+     AC_REQUIRE([AX_SOMETHING])dnl
+     AX_FOO
+     AX_BAR
+     ])
+
+   Wrapping the 'AC_PREREQ' call inside the macro ensures that Autoconf
+2.68 will not be required if 'AX_FOOBAR' is not actually used.  Most
+importantly, quoting the first argument of 'AC_DEFUN' allows the macro
+to be redefined or included twice (otherwise this first argument would
+be expanded during the second definition).  For consistency we like to
+quote even arguments such as '2.68' that do not require it.
+
+   If you have been directed here by the 'aclocal' diagnostic but are
+not the maintainer of the implicated macro, you will want to contact the
+maintainer of that macro.  Please make sure you have the latest version
+of the macro and that the problem hasn't already been reported before
+doing so: people tend to work faster when they aren't flooded by mails.
+
+   Another situation where 'aclocal' is commonly used is to manage
+macros that are used locally by the package, *note Local Macros::.

+
+6.3.4 Handling Local Macros
+---------------------------
+
+Feature tests offered by Autoconf do not cover all needs.  People often
+have to supplement existing tests with their own macros, or with
+third-party macros.
+
+   There are two ways to organize custom macros in a package.
+
+   The first possibility (the historical practice) is to list all your
+macros in 'acinclude.m4'.  This file will be included in 'aclocal.m4'
+when you run 'aclocal', and its macro(s) will henceforth be visible to
+'autoconf'.  However if it contains numerous macros, it will rapidly
+become difficult to maintain, and it will be almost impossible to share
+macros between packages.
+
+   The second possibility, which we do recommend, is to write each macro
+in its own file and gather all these files in a directory.  This
+directory is usually called 'm4/'.  Then it's enough to update
+'configure.ac' by adding a proper call to 'AC_CONFIG_MACRO_DIRS':
+
+     AC_CONFIG_MACRO_DIRS([m4])
+
+   'aclocal' will then take care of automatically adding 'm4/' to its
+search path for m4 files.
+
+   When 'aclocal' is run, it will build an 'aclocal.m4' that
+'m4_include's any file from 'm4/' that defines a required macro.  Macros
+not found locally will still be searched in system-wide directories, as
+explained in *note Macro Search Path::.
+
+   Custom macros should be distributed for the same reason that
+'configure.ac' is: so that other people have all the sources of your
+package if they want to work on it.  Actually, this distribution happens
+automatically because all 'm4_include'd files are distributed.
+
+   However there is no consensus on the distribution of third-party
+macros that your package may use.  Many libraries install their own
+macro in the system-wide 'aclocal' directory (*note Extending
+aclocal::).  For instance, Guile ships with a file called 'guile.m4'
+that contains the macro 'GUILE_FLAGS' that can be used to define setup
+compiler and linker flags appropriate for using Guile.  Using
+'GUILE_FLAGS' in 'configure.ac' will cause 'aclocal' to copy 'guile.m4'
+into 'aclocal.m4', but as 'guile.m4' is not part of the project, it will
+not be distributed.  Technically, that means a user who needs to rebuild
+'aclocal.m4' will have to install Guile first.  This is probably OK, if
+Guile already is a requirement to build the package.  However, if Guile
+is only an optional feature, or if your package might run on
+architectures where Guile cannot be installed, this requirement will
+hinder development.  An easy solution is to copy such third-party macros
+in your local 'm4/' directory so they get distributed.
+
+   Since Automake 1.10, 'aclocal' offers the option '--install' to copy
+these system-wide third-party macros in your local macro directory,
+helping to solve the above problem.
+
+   With this setup, system-wide macros will be copied to 'm4/' the first
+time you run 'aclocal'.  Then the locally installed macros will have
+precedence over the system-wide installed macros each time 'aclocal' is
+run again.
+
+   One reason why you should keep '--install' in the flags even after
+the first run is that when you later edit 'configure.ac' and depend on a
+new macro, this macro will be installed in your 'm4/' automatically.
+Another one is that serial numbers (*note Serials::) can be used to
+update the macros in your source tree automatically when new system-wide
+versions are installed.  A serial number should be a single line of the
+form
+
+     #serial NNN
+
+where NNN contains only digits and dots.  It should appear in the M4
+file before any macro definition.  It is a good practice to maintain a
+serial number for each macro you distribute, even if you do not use the
+'--install' option of 'aclocal': this allows other people to use it.

+
+6.3.5 Serial Numbers
+--------------------
+
+Because third-party macros defined in '*.m4' files are naturally shared
+between multiple projects, some people like to version them.  This makes
+it easier to tell which of two M4 files is newer.  Since at least 1996,
+the tradition is to use a '#serial' line for this.
+
+   A serial number should be a single line of the form
+
+     # serial VERSION
+
+where VERSION is a version number containing only digits and dots.
+Usually people use a single integer, and they increment it each time
+they change the macro (hence the name of "serial").  Such a line should
+appear in the M4 file before any macro definition.
+
+   The '#' must be the first character on the line, and it is OK to have
+extra words after the version, as in
+
+     #serial VERSION GARBAGE
+
+   Normally these serial numbers are completely ignored by 'aclocal' and
+'autoconf', like any genuine comment.  However when using 'aclocal''s
+'--install' feature, these serial numbers will modify the way 'aclocal'
+selects the macros to install in the package: if two files with the same
+basename exist in your search path, and if at least one of them uses a
+'#serial' line, 'aclocal' will ignore the file that has the older
+'#serial' line (or the file that has none).
+
+   Note that a serial number applies to a whole M4 file, not to any
+macro it contains.  A file can contains multiple macros, but only one
+serial.
+
+   Here is a use case that illustrates the use of '--install' and its
+interaction with serial numbers.  Let's assume we maintain a package
+called MyPackage, the 'configure.ac' of which requires a third-party
+macro 'AX_THIRD_PARTY' defined in '/usr/share/aclocal/thirdparty.m4' as
+follows:
+
+     # serial 1
+     AC_DEFUN([AX_THIRD_PARTY], [...])
+
+   MyPackage uses an 'm4/' directory to store local macros as explained
+in *note Local Macros::, and has
+
+     AC_CONFIG_MACRO_DIRS([m4])
+
+in its 'configure.ac'.
+
+   Initially the 'm4/' directory is empty.  The first time we run
+'aclocal --install', it will notice that
+
+   * 'configure.ac' uses 'AX_THIRD_PARTY'
+   * No local macros define 'AX_THIRD_PARTY'
+   * '/usr/share/aclocal/thirdparty.m4' defines 'AX_THIRD_PARTY' with
+     serial 1.
+
+Because '/usr/share/aclocal/thirdparty.m4' is a system-wide macro and
+'aclocal' was given the '--install' option, it will copy this file in
+'m4/thirdparty.m4', and output an 'aclocal.m4' that contains
+'m4_include([m4/thirdparty.m4])'.
+
+   The next time 'aclocal --install' is run, something different
+happens.  'aclocal' notices that
+
+   * 'configure.ac' uses 'AX_THIRD_PARTY'
+   * 'm4/thirdparty.m4' defines 'AX_THIRD_PARTY' with serial 1.
+   * '/usr/share/aclocal/thirdparty.m4' defines 'AX_THIRD_PARTY' with
+     serial 1.
+
+Because both files have the same serial number, 'aclocal' uses the first
+it found in its search path order (*note Macro Search Path::).
+'aclocal' therefore ignores '/usr/share/aclocal/thirdparty.m4' and
+outputs an 'aclocal.m4' that contains 'm4_include([m4/thirdparty.m4])'.
+
+   Local directories specified with '-I' are always searched before
+system-wide directories, so a local file will always be preferred to the
+system-wide file in case of equal serial numbers.
+
+   Now suppose the system-wide third-party macro is changed.  This can
+happen if the package installing this macro is updated.  Let's suppose
+the new macro has serial number 2.  The next time 'aclocal --install' is
+run the situation is the following:
+
+   * 'configure.ac' uses 'AX_THIRD_PARTY'
+   * 'm4/thirdparty.m4' defines 'AX_THIRD_PARTY' with serial 1.
+   * '/usr/share/aclocal/thirdparty.m4' defines 'AX_THIRD_PARTY' with
+     serial 2.
+
+When 'aclocal' sees a greater serial number, it immediately forgets
+anything it knows from files that have the same basename and a smaller
+serial number.  So after it has found '/usr/share/aclocal/thirdparty.m4'
+with serial 2, 'aclocal' will proceed as if it had never seen
+'m4/thirdparty.m4'.  This brings us back to a situation similar to that
+at the beginning of our example, where no local file defined the macro.
+'aclocal' will install the new version of the macro in
+'m4/thirdparty.m4', in this case overriding the old version.  MyPackage
+just had its macro updated as a side effect of running 'aclocal'.
+
+   If you are leery of letting 'aclocal' update your local macro, you
+can run 'aclocal --diff' to review the changes 'aclocal --install' would
+perform on these macros.
+
+   Finally, note that the '--force' option of 'aclocal' has absolutely
+no effect on the files installed by '--install'.  For instance, if you
+have modified your local macros, do not expect '--install --force' to
+replace the local macros by their system-wide versions.  If you want to
+do so, simply erase the local macros you want to revert, and run
+'aclocal --install'.

+
+6.3.6 The Future of 'aclocal'
+-----------------------------
+
+'aclocal' is expected to disappear.  This feature really should not be
+offered by Automake.  Automake should focus on generating 'Makefile's;
+dealing with M4 macros really is Autoconf's job.  The fact that some
+people install Automake just to use 'aclocal', but do not use 'automake'
+otherwise is an indication of how that feature is misplaced.
+
+   The new implementation will probably be done slightly differently.
+For instance, it could enforce the 'm4/'-style layout discussed in *note
+Local Macros::.
+
+   We have no idea when and how this will happen.  This has been
+discussed several times in the past, but someone still has to commit to
+that non-trivial task.
+
+   From the user point of view, 'aclocal''s removal might turn out to be
+painful.  There is a simple precaution that you may take to make that
+switch more seamless: never call 'aclocal' yourself.  Keep this guy
+under the exclusive control of 'autoreconf' and Automake's rebuild
+rules.  Hopefully you won't need to worry about things breaking, when
+'aclocal' disappears, because everything will have been taken care of.
+If otherwise you used to call 'aclocal' directly yourself or from some
+script, you will quickly notice the change.
+
+   Many packages come with a script called 'bootstrap.sh' or
+'autogen.sh', that will just call 'aclocal', 'libtoolize', 'gettextize'
+or 'autopoint', 'autoconf', 'autoheader', and 'automake' in the right
+order.  Actually this is precisely what 'autoreconf' can do for you.  If
+your package has such a 'bootstrap.sh' or 'autogen.sh' script, consider
+using 'autoreconf'.  That should simplify its logic a lot (less things
+to maintain, yum!), it's even likely you will not need the script
+anymore, and more to the point you will not call 'aclocal' directly
+anymore.
+
+   For the time being, third-party packages should continue to install
+public macros into '/usr/share/aclocal/'.  If 'aclocal' is replaced by
+another tool it might make sense to rename the directory, but supporting
+'/usr/share/aclocal/' for backward compatibility should be really easy
+provided all macros are properly written (*note Extending aclocal::).

+6.4 Autoconf macros supplied with Automake

+

+'configure.ac'.  When you use one of them it will be included by
+'aclocal' in 'aclocal.m4'.

+
+
+File: automake.info,  Node: Public Macros,  Next: Obsolete Macros,  Up: Macros
+
+6.4.1 Public Macros
+-------------------
+
+'AM_INIT_AUTOMAKE([OPTIONS])'
+     Runs many macros required for proper operation of the generated
+     Makefiles.
+
+     Today, 'AM_INIT_AUTOMAKE' is called with a single argument: a
+     space-separated list of Automake options that should be applied to
+     every 'Makefile.am' in the tree.  The effect is as if each option
+     were listed in 'AUTOMAKE_OPTIONS' (*note Options::).
+
+     This macro can also be called in another, _deprecated_ form:
+     'AM_INIT_AUTOMAKE(PACKAGE, VERSION, [NO-DEFINE])'.  In this form,
+     there are two required arguments: the package and the version
+     number.  This usage is mostly obsolete because the PACKAGE and
+     VERSION can be obtained from Autoconf's 'AC_INIT' macro.  However,
+     differently from what happens for 'AC_INIT' invocations, this
+     'AM_INIT_AUTOMAKE' invocation supports shell variables' expansions
+     in the 'PACKAGE' and 'VERSION' arguments, and this can be still be
+     useful in some selected situations.  Our hope is that future
+     Autoconf versions will improve their support for package versions
+     defined dynamically at configure runtime; when (and if) this
+     happens, support for the two-args 'AM_INIT_AUTOMAKE' invocation
+     will likely be removed from Automake.
+
+     If your 'configure.ac' has:
+
+          AC_INIT([src/foo.c])
+          AM_INIT_AUTOMAKE([mumble], [1.5])
+
+     you should modernize it as follows:
+
+          AC_INIT([mumble], [1.5])
+          AC_CONFIG_SRCDIR([src/foo.c])
+          AM_INIT_AUTOMAKE
+
+     Note that if you're upgrading your 'configure.ac' from an earlier
+     version of Automake, it is not always correct to simply move the
+     package and version arguments from 'AM_INIT_AUTOMAKE' directly to
+     'AC_INIT', as in the example above.  The first argument to
+     'AC_INIT' should be the name of your package (e.g., 'GNU
+     Automake'), not the tarball name (e.g., 'automake') that you used
+     to pass to 'AM_INIT_AUTOMAKE'.  Autoconf tries to derive a tarball
+     name from the package name, which should work for most but not all
+     package names.  (If it doesn't work for yours, you can use the
+     four-argument form of 'AC_INIT' to provide the tarball name
+     explicitly).
+
+     By default this macro 'AC_DEFINE''s 'PACKAGE' and 'VERSION'.  This
+     can be avoided by passing the 'no-define' option (*note List of
+     Automake options::):
+          AM_INIT_AUTOMAKE([no-define ...])
+
+'AM_PATH_LISPDIR'
+     Searches for the program 'emacs', and, if found, sets the output
+     variable 'lispdir' to the full path to Emacs' site-lisp directory.
+
+     Note that this test assumes the 'emacs' found to be a version that
+     supports Emacs Lisp (such as GNU Emacs or XEmacs).  Other emacsen
+     can cause this test to hang (some, like old versions of MicroEmacs,
+     start up in interactive mode, requiring 'C-x C-c' to exit, which is
+     hardly obvious for a non-emacs user).  In most cases, however, you
+     should be able to use 'C-c' to kill the test.  In order to avoid
+     problems, you can set 'EMACS' to "no" in the environment, or use
+     the '--with-lispdir' option to 'configure' to explicitly set the
+     correct path (if you're sure you have an 'emacs' that supports
+     Emacs Lisp).
+
+'AM_PROG_AR([ACT-IF-FAIL])'
+     You must use this macro when you use the archiver in your project,
+     if you want support for unusual archivers such as Microsoft 'lib'.
+     The content of the optional argument is executed if the archiver
+     interface is not recognized; the default action is to abort
+     configure with an error message.
+
+'AM_PROG_AS'
+     Use this macro when you have assembly code in your project.  This
+     will choose the assembler for you (by default the C compiler) and
+     set 'CCAS', and will also set 'CCASFLAGS' if required.
+
+'AM_PROG_CC_C_O'
+     This is an obsolescent macro that checks that the C compiler
+     supports the '-c' and '-o' options together.  Note that, since
+     Automake 1.14, the 'AC_PROG_CC' is rewritten to implement such
+     checks itself, and thus the explicit use of 'AM_PROG_CC_C_O' should
+     no longer be required.
+
+'AM_PROG_LEX'
+     Like 'AC_PROG_LEX' (*note Particular Program Checks:
+     (autoconf)Particular Programs.), but uses the 'missing' script on
+     systems that do not have 'lex'.  HP-UX 10 is one such system.
+
+'AM_PROG_GCJ'
+     This macro finds the 'gcj' program or causes an error.  It sets
+     'GCJ' and 'GCJFLAGS'.  'gcj' is the Java front-end to the GNU
+     Compiler Collection.
+
+'AM_PROG_UPC([COMPILER-SEARCH-LIST])'
+     Find a compiler for Unified Parallel C and define the 'UPC'
+     variable.  The default COMPILER-SEARCH-LIST is 'upcc upc'.  This
+     macro will abort 'configure' if no Unified Parallel C compiler is
+     found.
+
+'AM_MISSING_PROG(NAME, PROGRAM)'
+     Find a maintainer tool PROGRAM and define the NAME environment
+     variable with its location.  If PROGRAM is not detected, then NAME
+     will instead invoke the 'missing' script, in order to give useful
+     advice to the user about the missing maintainer tool.  *Note
+     maintainer-mode::, for more information on when the 'missing'
+     script is appropriate.
+
+'AM_SILENT_RULES'
+     Control the machinery for less verbose build output (*note Automake
+     Silent Rules::).
+
+'AM_WITH_DMALLOC'
+     Add support for the Dmalloc package (http://dmalloc.com/).  If the
+     user runs 'configure' with '--with-dmalloc', then define
+     'WITH_DMALLOC' and add '-ldmalloc' to 'LIBS'.

+6.4.2 Obsolete Macros
+---------------------
+
+Although using some of the following macros was required in past
+releases, you should not use any of them in new code.  _All these macros
+will be removed in the next major Automake version_; if you are still
+using them, running 'autoupdate' should adjust your 'configure.ac'
+automatically (*note Using 'autoupdate' to Modernize 'configure.ac':
+(autoconf)autoupdate Invocation.).  _Do it NOW!_
+
+'AM_PROG_MKDIR_P'
+
+     From Automake 1.8 to 1.9.6 this macro used to define the output
+     variable 'mkdir_p' to one of 'mkdir -p', 'install-sh -d', or
+     'mkinstalldirs'.
+
+     Nowadays Autoconf provides a similar functionality with
+     'AC_PROG_MKDIR_P' (*note Particular Program Checks:
+     (autoconf)Particular Programs.), however this defines the output
+     variable 'MKDIR_P' instead.  In case you are still using the
+     'AM_PROG_MKDIR_P' macro in your 'configure.ac', or its provided
+     variable '$(mkdir_p)' in your 'Makefile.am', you are advised to
+     switch ASAP to the more modern Autoconf-provided interface instead;
+     both the macro and the variable might be removed in a future major

+     required, and there should be no need to invoke them manually.
+
+'AM_MAKE_INCLUDE'
+     This macro is used to discover how the user's 'make' handles
+     'include' statements.  This macro is automatically invoked when
+     needed; there should be no need to invoke it manually.
+
+'AM_PROG_INSTALL_STRIP'
+     This is used to find a version of 'install' that can be used to
+     strip a program at installation time.  This macro is automatically
+     included when required.
+
+'AM_SANITY_CHECK'
+     This checks to make sure that a file created in the build directory
+     is newer than a file in the source directory.  This can fail on
+     systems where the clock is set incorrectly.  This macro is
+     automatically run from 'AM_INIT_AUTOMAKE'.

+7 Directories
+*************
+
+For simple projects that distribute all files in the same directory it
+is enough to have a single 'Makefile.am' that builds everything in
+place.
+
+   In larger projects, it is common to organize files in different
+directories, in a tree.  For example, there could be a directory for the
+program's source, one for the testsuite, and one for the documentation;
+or, for very large projects, there could be one directory per program,
+per library or per module.
+
+   The traditional approach is to build these subdirectories
+recursively, employing _make recursion_: each directory contains its own
+'Makefile', and when 'make' is run from the top-level directory, it
+enters each subdirectory in turn, and invokes there a new 'make'
+instance to build the directory's contents.
+
+   Because this approach is very widespread, Automake offers built-in
+support for it.  However, it is worth nothing that the use of make
+recursion has its own serious issues and drawbacks, and that it's well
+possible to have packages with a multi directory layout that make little
+or no use of such recursion (examples of such packages are GNU Bison and
+GNU Automake itself); see also the *note Alternative:: section below.

+
+7.1 Recursing subdirectories
+============================
+
+In packages using make recursion, the top level 'Makefile.am' must tell
+Automake which subdirectories are to be built.  This is done via the
+'SUBDIRS' variable.
+
+   The 'SUBDIRS' variable holds a list of subdirectories in which
+building of various sorts can occur.  The rules for many targets (e.g.,
+'all') in the generated 'Makefile' will run commands both locally and in
+all specified subdirectories.  Note that the directories listed in
+'SUBDIRS' are not required to contain 'Makefile.am's; only 'Makefile's
+(after configuration).  This allows inclusion of libraries from packages
+that do not use Automake (such as 'gettext'; see also *note Third-Party
+Makefiles::).
+
+   In packages that use subdirectories, the top-level 'Makefile.am' is
+often very short.  For instance, here is the 'Makefile.am' from the GNU
+Hello distribution:
+
+     EXTRA_DIST = BUGS ChangeLog.O README-alpha
+     SUBDIRS = doc intl po src tests
+
+   When Automake invokes 'make' in a subdirectory, it uses the value of
+the 'MAKE' variable.  It passes the value of the variable 'AM_MAKEFLAGS'
+to the 'make' invocation; this can be set in 'Makefile.am' if there are
+flags you must always pass to 'make'.
+
+   The directories mentioned in 'SUBDIRS' are usually direct children of
+the current directory, each subdirectory containing its own
+'Makefile.am' with a 'SUBDIRS' pointing to deeper subdirectories.
+Automake can be used to construct packages of arbitrary depth this way.
+
+   By default, Automake generates 'Makefiles' that work depth-first in
+postfix order: the subdirectories are built before the current
+directory.  However, it is possible to change this ordering.  You can do
+this by putting '.' into 'SUBDIRS'.  For instance, putting '.' first
+will cause a prefix ordering of directories.
+
+   Using
+
+     SUBDIRS = lib src . test
+
+will cause 'lib/' to be built before 'src/', then the current directory
+will be built, finally the 'test/' directory will be built.  It is
+customary to arrange test directories to be built after everything else
+since they are meant to test what has been constructed.
+
+   In addition to the built-in recursive targets defined by Automake
+('all', 'check', etc.), the developer can also define his own recursive
+targets.  That is done by passing the names of such targets as arguments
+to the m4 macro 'AM_EXTRA_RECURSIVE_TARGETS' in 'configure.ac'.
+Automake generates rules to handle the recursion for such targets; and
+the developer can define real actions for them by defining corresponding
+'-local' targets.

+7.2 Conditional Subdirectories
+==============================
+
+It is possible to define the 'SUBDIRS' variable conditionally if, like
+in the case of GNU Inetutils, you want to only build a subset of the
+entire package.
+
+   To illustrate how this works, let's assume we have two directories
+'src/' and 'opt/'.  'src/' should always be built, but we want to decide
+in 'configure' whether 'opt/' will be built or not.  (For this example
+we will assume that 'opt/' should be built when the variable '$want_opt'
+was set to 'yes'.)
+
+   Running 'make' should thus recurse into 'src/' always, and then maybe
+in 'opt/'.
+
+   However 'make dist' should always recurse into both 'src/' and
+'opt/'.  Because 'opt/' should be distributed even if it is not needed
+in the current configuration.  This means 'opt/Makefile' should be
+created _unconditionally_.
+
+   There are two ways to setup a project like this.  You can use
+Automake conditionals (*note Conditionals::) or use Autoconf 'AC_SUBST'
+variables (*note Setting Output Variables: (autoconf)Setting Output
+Variables.).  Using Automake conditionals is the preferred solution.
+Before we illustrate these two possibilities, let's introduce
+'DIST_SUBDIRS'.
+
+* Menu:
+
+* SUBDIRS vs DIST_SUBDIRS::     Two sets of directories
+* Subdirectories with AM_CONDITIONAL::  Specifying conditional subdirectories
+* Subdirectories with AC_SUBST::  Another way for conditional recursion
+* Unconfigured Subdirectories::  Not even creating a 'Makefile'

+
+7.2.1 'SUBDIRS' vs. 'DIST_SUBDIRS'
+----------------------------------
+
+Automake considers two sets of directories, defined by the variables
+'SUBDIRS' and 'DIST_SUBDIRS'.
+
+   'SUBDIRS' contains the subdirectories of the current directory that
+must be built (*note Subdirectories::).  It must be defined manually;
+Automake will never guess a directory is to be built.  As we will see in
+the next two sections, it is possible to define it conditionally so that
+some directory will be omitted from the build.
+
+   'DIST_SUBDIRS' is used in rules that need to recurse in all
+directories, even those that have been conditionally left out of the
+build.  Recall our example where we may not want to build subdirectory
+'opt/', but yet we want to distribute it?  This is where 'DIST_SUBDIRS'
+comes into play: 'opt' may not appear in 'SUBDIRS', but it must appear
+in 'DIST_SUBDIRS'.
+
+   Precisely, 'DIST_SUBDIRS' is used by 'make maintainer-clean', 'make
+distclean' and 'make dist'.  All other recursive rules use 'SUBDIRS'.
+
+   If 'SUBDIRS' is defined conditionally using Automake conditionals,
+Automake will define 'DIST_SUBDIRS' automatically from the possible
+values of 'SUBDIRS' in all conditions.
+
+   If 'SUBDIRS' contains 'AC_SUBST' variables, 'DIST_SUBDIRS' will not
+be defined correctly because Automake does not know the possible values
+of these variables.  In this case 'DIST_SUBDIRS' needs to be defined
+manually.
+

+
+7.2.2 Subdirectories with 'AM_CONDITIONAL'
+------------------------------------------
+
+'configure' should output the 'Makefile' for each directory and define a
+condition into which 'opt/' should be built.
+
+     ...
+     AM_CONDITIONAL([COND_OPT], [test "$want_opt" = yes])
+     AC_CONFIG_FILES([Makefile src/Makefile opt/Makefile])
+     ...
+
+   Then 'SUBDIRS' can be defined in the top-level 'Makefile.am' as
+follows.
+
+     if COND_OPT
+       MAYBE_OPT = opt
+     endif
+     SUBDIRS = src $(MAYBE_OPT)
+
+   As you can see, running 'make' will rightly recurse into 'src/' and
+maybe 'opt/'.
+
+   As you can't see, running 'make dist' will recurse into both 'src/'
+and 'opt/' directories because 'make dist', unlike 'make all', doesn't
+use the 'SUBDIRS' variable.  It uses the 'DIST_SUBDIRS' variable.
+
+   In this case Automake will define 'DIST_SUBDIRS = src opt'
+automatically because it knows that 'MAYBE_OPT' can contain 'opt' in
+some condition.

+
+7.2.3 Subdirectories with 'AC_SUBST'
+------------------------------------
+
+Another possibility is to define 'MAYBE_OPT' from './configure' using
+'AC_SUBST':
+
+     ...
+     if test "$want_opt" = yes; then
+       MAYBE_OPT=opt
+     else
+       MAYBE_OPT=
+     fi
+     AC_SUBST([MAYBE_OPT])
+     AC_CONFIG_FILES([Makefile src/Makefile opt/Makefile])
+     ...
+
+   In this case the top-level 'Makefile.am' should look as follows.
+
+     SUBDIRS = src $(MAYBE_OPT)
+     DIST_SUBDIRS = src opt
+
+   The drawback is that since Automake cannot guess what the possible
+values of 'MAYBE_OPT' are, it is necessary to define 'DIST_SUBDIRS'.
+
+
+File: automake.info,  Node: Unconfigured Subdirectories,  Prev: Subdirectories with AC_SUBST,  Up: Conditional Subdirectories
+
+7.2.4 Unconfigured Subdirectories
+---------------------------------
+
+The semantics of 'DIST_SUBDIRS' are often misunderstood by some users
+that try to _configure and build_ subdirectories conditionally.  Here by
+configuring we mean creating the 'Makefile' (it might also involve
+running a nested 'configure' script: this is a costly operation that
+explains why people want to do it conditionally, but only the 'Makefile'
+is relevant to the discussion).
+
+   The above examples all assume that every 'Makefile' is created, even
+in directories that are not going to be built.  The simple reason is
+that we want 'make dist' to distribute even the directories that are not
+being built (e.g., platform-dependent code), hence 'make dist' must
+recurse into the subdirectory, hence this directory must be configured
+and appear in 'DIST_SUBDIRS'.
+
+   Building packages that do not configure every subdirectory is a
+tricky business, and we do not recommend it to the novice as it is easy
+to produce an incomplete tarball by mistake.  We will not discuss this
+topic in depth here, yet for the adventurous here are a few rules to
+remember.
+
+   * 'SUBDIRS' should always be a subset of 'DIST_SUBDIRS'.
+
+     It makes little sense to have a directory in 'SUBDIRS' that is not
+     in 'DIST_SUBDIRS'.  Think of the former as a way to tell which
+     directories listed in the latter should be built.
+   * Any directory listed in 'DIST_SUBDIRS' and 'SUBDIRS' must be
+     configured.
+
+     I.e., the 'Makefile' must exists or the recursive 'make' rules will
+     not be able to process the directory.
+   * Any configured directory must be listed in 'DIST_SUBDIRS'.
+
+     So that the cleaning rules remove the generated 'Makefile's.  It
+     would be correct to see 'DIST_SUBDIRS' as a variable that lists all
+     the directories that have been configured.
+
+   In order to prevent recursion in some unconfigured directory you must
+therefore ensure that this directory does not appear in 'DIST_SUBDIRS'
+(and 'SUBDIRS').  For instance, if you define 'SUBDIRS' conditionally
+using 'AC_SUBST' and do not define 'DIST_SUBDIRS' explicitly, it will be
+default to '$(SUBDIRS)'; another possibility is to force 'DIST_SUBDIRS =
+$(SUBDIRS)'.
+
+   Of course, directories that are omitted from 'DIST_SUBDIRS' will not
+be distributed unless you make other arrangements for this to happen
+(for instance, always running 'make dist' in a configuration where all
+directories are known to appear in 'DIST_SUBDIRS'; or writing a
+'dist-hook' target to distribute these directories).
+
+   In few packages, unconfigured directories are not even expected to be
+distributed.  Although these packages do not require the aforementioned
+extra arrangements, there is another pitfall.  If the name of a
+directory appears in 'SUBDIRS' or 'DIST_SUBDIRS', 'automake' will make
+sure the directory exists.  Consequently 'automake' cannot be run on
+such a distribution when one directory has been omitted.  One way to
+avoid this check is to use the 'AC_SUBST' method to declare conditional
+directories; since 'automake' does not know the values of 'AC_SUBST'
+variables it cannot ensure the corresponding directory exists.

+
+7.3 An Alternative Approach to Subdirectories
+=============================================
+
+If you've ever read Peter Miller's excellent paper, Recursive Make
+Considered Harmful (http://miller.emu.id.au/pmiller/books/rmch/), the
+preceding sections on the use of make recursion will probably come as
+unwelcome advice.  For those who haven't read the paper, Miller's main
+thesis is that recursive 'make' invocations are both slow and
+error-prone.
+
+   Automake provides sufficient cross-directory support (1) to enable
+you to write a single 'Makefile.am' for a complex multi-directory
+package.
+
+   By default an installable file specified in a subdirectory will have
+its directory name stripped before installation.  For instance, in this
+example, the header file will be installed as '$(includedir)/stdio.h':
+
+     include_HEADERS = inc/stdio.h
+
+   However, the 'nobase_' prefix can be used to circumvent this path
+stripping.  In this example, the header file will be installed as
+'$(includedir)/sys/types.h':
+
+     nobase_include_HEADERS = sys/types.h
+
+   'nobase_' should be specified first when used in conjunction with
+either 'dist_' or 'nodist_' (*note Fine-grained Distribution Control::).
+For instance:
+
+     nobase_dist_pkgdata_DATA = images/vortex.pgm sounds/whirl.ogg
+
+   Finally, note that a variable using the 'nobase_' prefix can often be
+replaced by several variables, one for each destination directory (*note
+Uniform::).  For instance, the last example could be rewritten as
+follows:
+
+     imagesdir = $(pkgdatadir)/images
+     soundsdir = $(pkgdatadir)/sounds
+     dist_images_DATA = images/vortex.pgm
+     dist_sounds_DATA = sounds/whirl.ogg
+
+This latter syntax makes it possible to change one destination directory
+without changing the layout of the source tree.
+
+   Currently, 'nobase_*_LTLIBRARIES' are the only exception to this
+rule, in that there is no particular installation order guarantee for an
+otherwise equivalent set of variables without 'nobase_' prefix.

+
+7.4 Nesting Packages
+====================
+
+In the GNU Build System, packages can be nested to arbitrary depth.
+This means that a package can embed other packages with their own
+'configure', 'Makefile's, etc.
+
+   These other packages should just appear as subdirectories of their
+parent package.  They must be listed in 'SUBDIRS' like other ordinary
+directories.  However the subpackage's 'Makefile's should be output by
+its own 'configure' script, not by the parent's 'configure'.  This is
+achieved using the 'AC_CONFIG_SUBDIRS' Autoconf macro (*note
+AC_CONFIG_SUBDIRS: (autoconf)Subdirectories.).
+
+   Here is an example package for an 'arm' program that links with a
+'hand' library that is a nested package in subdirectory 'hand/'.
+
+   'arm''s 'configure.ac':
+
+     AC_INIT([arm], [1.0])
+     AC_CONFIG_AUX_DIR([.])
+     AM_INIT_AUTOMAKE
+     AC_PROG_CC
+     AC_CONFIG_FILES([Makefile])
+     # Call hand's ./configure script recursively.
+     AC_CONFIG_SUBDIRS([hand])
+     AC_OUTPUT
+
+   'arm''s 'Makefile.am':
+
+     # Build the library in the hand subdirectory first.
+     SUBDIRS = hand
+
+     # Include hand's header when compiling this directory.
+     AM_CPPFLAGS = -I$(srcdir)/hand
+
+     bin_PROGRAMS = arm
+     arm_SOURCES = arm.c
+     # link with the hand library.
+     arm_LDADD = hand/libhand.a
+
+   Now here is 'hand''s 'hand/configure.ac':
+
+     AC_INIT([hand], [1.2])
+     AC_CONFIG_AUX_DIR([.])
+     AM_INIT_AUTOMAKE
+     AC_PROG_CC
+     AM_PROG_AR
+     AC_PROG_RANLIB
+     AC_CONFIG_FILES([Makefile])
+     AC_OUTPUT
+
+and its 'hand/Makefile.am':
+
+     lib_LIBRARIES = libhand.a
+     libhand_a_SOURCES = hand.c
+
+   When 'make dist' is run from the top-level directory it will create
+an archive 'arm-1.0.tar.gz' that contains the 'arm' code as well as the
+'hand' subdirectory.  This package can be built and installed like any
+ordinary package, with the usual './configure && make && make install'
+sequence (the 'hand' subpackage will be built and installed by the
+process).
+
+   When 'make dist' is run from the hand directory, it will create a
+self-contained 'hand-1.2.tar.gz' archive.  So although it appears to be
+embedded in another package, it can still be used separately.
+
+   The purpose of the 'AC_CONFIG_AUX_DIR([.])' instruction is to force
+Automake and Autoconf to search for auxiliary scripts in the current
+directory.  For instance, this means that there will be two copies of
+'install-sh': one in the top-level of the 'arm' package, and another one
+in the 'hand/' subdirectory for the 'hand' package.
+
+   The historical default is to search for these auxiliary scripts in
+the parent directory and the grandparent directory.  So if the
+'AC_CONFIG_AUX_DIR([.])' line was removed from 'hand/configure.ac', that
+subpackage would share the auxiliary script of the 'arm' package.  This
+may looks like a gain in size (a few kilobytes), but it is actually a
+loss of modularity as the 'hand' subpackage is no longer self-contained
+('make dist' in the subdirectory will not work anymore).
+
+   Packages that do not use Automake need more work to be integrated
+this way.  *Note Third-Party Makefiles::.

+8.1 Building a program
+======================
+
+In order to build a program, you need to tell Automake which sources are
+part of it, and which libraries it should be linked with.
+
+   This section also covers conditional compilation of sources or
+programs.  Most of the comments about these also apply to libraries

+* Conditional Programs::        Building a program conditionally
+
+
+File: automake.info,  Node: Program Sources,  Next: Linking,  Up: A Program
+
+8.1.1 Defining program sources
+------------------------------
+
+In a directory containing source that gets built into a program (as
+opposed to a library or a script), the 'PROGRAMS' primary is used.
+Programs can be installed in 'bindir', 'sbindir', 'libexecdir',
+'pkglibexecdir', or not at all ('noinst_').  They can also be built only
+for 'make check', in which case the prefix is 'check_'.
+
+   For instance:
+
+     bin_PROGRAMS = hello
+
+   In this simple case, the resulting 'Makefile.in' will contain code to
+generate a program named 'hello'.
+
+   Associated with each program are several assisting variables that are
+named after the program.  These variables are all optional, and have
+reasonable defaults.  Each variable, its use, and default is spelled out
+below; we use the "hello" example throughout.
+
+   The variable 'hello_SOURCES' is used to specify which source files
+get built into an executable:
+
+     hello_SOURCES = hello.c version.c getopt.c getopt1.c getopt.h system.h
+
+   This causes each mentioned '.c' file to be compiled into the
+corresponding '.o'.  Then all are linked to produce 'hello'.
+
+   If 'hello_SOURCES' is not specified, then it defaults to the single
+file 'hello.c' (*note Default _SOURCES::).
+
+   Multiple programs can be built in a single directory.  Multiple
+programs can share a single source file, which must be listed in each
+'_SOURCES' definition.
+
+   Header files listed in a '_SOURCES' definition will be included in
+the distribution but otherwise ignored.  In case it isn't obvious, you
+should not include the header file generated by 'configure' in a
+'_SOURCES' variable; this file should not be distributed.  Lex ('.l')
+and Yacc ('.y') files can also be listed; see *note Yacc and Lex::.
+
+
+File: automake.info,  Node: Linking,  Next: Conditional Sources,  Prev: Program Sources,  Up: A Program
+
+8.1.2 Linking the program
+-------------------------
+
+If you need to link against libraries that are not found by 'configure',
+you can use 'LDADD' to do so.  This variable is used to specify
+additional objects or libraries to link with; it is inappropriate for
+specifying specific linker flags, you should use 'AM_LDFLAGS' for this
+purpose.
+
+   Sometimes, multiple programs are built in one directory but do not
+share the same link-time requirements.  In this case, you can use the
+'PROG_LDADD' variable (where PROG is the name of the program as it
+appears in some '_PROGRAMS' variable, and usually written in lowercase)
+to override 'LDADD'.  If this variable exists for a given program, then
+that program is not linked using 'LDADD'.
+
+   For instance, in GNU cpio, 'pax', 'cpio' and 'mt' are linked against
+the library 'libcpio.a'.  However, 'rmt' is built in the same directory,
+and has no such link requirement.  Also, 'mt' and 'rmt' are only built
+on certain architectures.  Here is what cpio's 'src/Makefile.am' looks
+like (abridged):
+
+     bin_PROGRAMS = cpio pax $(MT)
+     libexec_PROGRAMS = $(RMT)
+     EXTRA_PROGRAMS = mt rmt
+
+     LDADD = ../lib/libcpio.a $(INTLLIBS)
+     rmt_LDADD =
+
+     cpio_SOURCES = ...
+     pax_SOURCES = ...
+     mt_SOURCES = ...
+     rmt_SOURCES = ...
+
+   'PROG_LDADD' is inappropriate for passing program-specific linker
+flags (except for '-l', '-L', '-dlopen' and '-dlpreopen').  So, use the
+'PROG_LDFLAGS' variable for this purpose.
+
+   It is also occasionally useful to have a program depend on some other
+target that is not actually part of that program.  This can be done
+using either the 'PROG_DEPENDENCIES' or the 'EXTRA_PROG_DEPENDENCIES'
+variable.  Each program depends on the contents both variables, but no
+further interpretation is done.
+
+   Since these dependencies are associated to the link rule used to
+create the programs they should normally list files used by the link
+command.  That is '*.$(OBJEXT)', '*.a', or '*.la' files.  In rare cases
+you may need to add other kinds of files such as linker scripts, but
+_listing a source file in '_DEPENDENCIES' is wrong_.  If some source
+file needs to be built before all the components of a program are built,
+consider using the 'BUILT_SOURCES' variable instead (*note Sources::).
+
+   If 'PROG_DEPENDENCIES' is not supplied, it is computed by Automake.
+The automatically-assigned value is the contents of 'PROG_LDADD', with
+most configure substitutions, '-l', '-L', '-dlopen' and '-dlpreopen'
+options removed.  The configure substitutions that are left in are only
+'$(LIBOBJS)' and '$(ALLOCA)'; these are left because it is known that
+they will not cause an invalid value for 'PROG_DEPENDENCIES' to be
+generated.
+
+   *note Conditional Sources:: shows a situation where '_DEPENDENCIES'
+may be used.
+
+   The 'EXTRA_PROG_DEPENDENCIES' may be useful for cases where you
+merely want to augment the 'automake'-generated 'PROG_DEPENDENCIES'
+rather than replacing it.
+
+   We recommend that you avoid using '-l' options in 'LDADD' or
+'PROG_LDADD' when referring to libraries built by your package.
+Instead, write the file name of the library explicitly as in the above
+'cpio' example.  Use '-l' only to list third-party libraries.  If you
+follow this rule, the default value of 'PROG_DEPENDENCIES' will list all
+your local libraries and omit the other ones.
+
+
+File: automake.info,  Node: Conditional Sources,  Next: Conditional Programs,  Prev: Linking,  Up: A Program
+
+8.1.3 Conditional compilation of sources
+----------------------------------------
+
+You can't put a configure substitution (e.g., '@FOO@' or '$(FOO)' where
+'FOO' is defined via 'AC_SUBST') into a '_SOURCES' variable.  The reason
+for this is a bit hard to explain, but suffice to say that it simply
+won't work.  Automake will give an error if you try to do this.
+
+   Fortunately there are two other ways to achieve the same result.  One
+is to use configure substitutions in '_LDADD' variables, the other is to
+use an Automake conditional.
+
+Conditional Compilation using '_LDADD' Substitutions
+....................................................
+
+Automake must know all the source files that could possibly go into a
+program, even if not all the files are built in every circumstance.  Any
+files that are only conditionally built should be listed in the
+appropriate 'EXTRA_' variable.  For instance, if 'hello-linux.c' or
+'hello-generic.c' were conditionally included in 'hello', the
+'Makefile.am' would contain:
+
+     bin_PROGRAMS = hello
+     hello_SOURCES = hello-common.c
+     EXTRA_hello_SOURCES = hello-linux.c hello-generic.c
+     hello_LDADD = $(HELLO_SYSTEM)
+     hello_DEPENDENCIES = $(HELLO_SYSTEM)
+
+You can then setup the '$(HELLO_SYSTEM)' substitution from
+'configure.ac':
+
+     ...
+     case $host in
+       *linux*) HELLO_SYSTEM='hello-linux.$(OBJEXT)' ;;
+       *)       HELLO_SYSTEM='hello-generic.$(OBJEXT)' ;;
+     esac
+     AC_SUBST([HELLO_SYSTEM])
+     ...
+
+   In this case, the variable 'HELLO_SYSTEM' should be replaced by
+either 'hello-linux.o' or 'hello-generic.o', and added to both
+'hello_DEPENDENCIES' and 'hello_LDADD' in order to be built and linked
+in.
+
+Conditional Compilation using Automake Conditionals
+...................................................
+
+An often simpler way to compile source files conditionally is to use
+Automake conditionals.  For instance, you could use this 'Makefile.am'
+construct to build the same 'hello' example:
+
+     bin_PROGRAMS = hello
+     if LINUX
+     hello_SOURCES = hello-linux.c hello-common.c
+     else
+     hello_SOURCES = hello-generic.c hello-common.c
+     endif
+
+   In this case, 'configure.ac' should setup the 'LINUX' conditional
+using 'AM_CONDITIONAL' (*note Conditionals::).
+
+   When using conditionals like this you don't need to use the 'EXTRA_'
+variable, because Automake will examine the contents of each variable to
+construct the complete list of source files.
+
+   If your program uses a lot of files, you will probably prefer a
+conditional '+='.
+
+     bin_PROGRAMS = hello
+     hello_SOURCES = hello-common.c
+     if LINUX
+     hello_SOURCES += hello-linux.c
+     else
+     hello_SOURCES += hello-generic.c
+     endif

+Sometimes it is useful to determine the programs that are to be built at
+configure time.  For instance, GNU 'cpio' only builds 'mt' and 'rmt'
+under special circumstances.  The means to achieve conditional
+compilation of programs are the same you can use to compile source files
+conditionally: substitutions or conditionals.
+
+Conditional Programs using 'configure' Substitutions
+....................................................
+
+In this case, you must notify Automake of all the programs that can
+possibly be built, but at the same time cause the generated
+'Makefile.in' to use the programs specified by 'configure'.  This is
+done by having 'configure' substitute values into each '_PROGRAMS'
+definition, while listing all optionally built programs in
+'EXTRA_PROGRAMS'.
+
+     bin_PROGRAMS = cpio pax $(MT)
+     libexec_PROGRAMS = $(RMT)
+     EXTRA_PROGRAMS = mt rmt
+
+   As explained in *note EXEEXT::, Automake will rewrite 'bin_PROGRAMS',
+'libexec_PROGRAMS', and 'EXTRA_PROGRAMS', appending '$(EXEEXT)' to each
+binary.  Obviously it cannot rewrite values obtained at run-time through
+'configure' substitutions, therefore you should take care of appending
+'$(EXEEXT)' yourself, as in 'AC_SUBST([MT], ['mt${EXEEXT}'])'.
+
+Conditional Programs using Automake Conditionals
+................................................
+
+You can also use Automake conditionals (*note Conditionals::) to select
+programs to be built.  In this case you don't have to worry about
+'$(EXEEXT)' or 'EXTRA_PROGRAMS'.
+
+     bin_PROGRAMS = cpio pax
+     if WANT_MT
+       bin_PROGRAMS += mt
+     endif
+     if WANT_RMT
+       libexec_PROGRAMS = rmt

+8.2 Building a library
+======================
+
+Building a library is much like building a program.  In this case, the
+name of the primary is 'LIBRARIES'.  Libraries can be installed in
+'libdir' or 'pkglibdir'.
+
+   *Note A Shared Library::, for information on how to build shared
+libraries using libtool and the 'LTLIBRARIES' primary.
+
+   Each '_LIBRARIES' variable is a list of the libraries to be built.
+For instance, to create a library named 'libcpio.a', but not install it,
+you would write:
+
+     noinst_LIBRARIES = libcpio.a
+     libcpio_a_SOURCES = ...
+
+   The sources that go into a library are determined exactly as they are
+for programs, via the '_SOURCES' variables.  Note that the library name
+is canonicalized (*note Canonicalization::), so the '_SOURCES' variable
+corresponding to 'libcpio.a' is 'libcpio_a_SOURCES', not
+'libcpio.a_SOURCES'.
+
+   Extra objects can be added to a library using the 'LIBRARY_LIBADD'
+variable.  This should be used for objects determined by 'configure'.
+Again from 'cpio':
+
+     libcpio_a_LIBADD = $(LIBOBJS) $(ALLOCA)
+
+   In addition, sources for extra objects that will not exist until
+configure-time must be added to the 'BUILT_SOURCES' variable (*note
+Sources::).
+
+   Building a static library is done by compiling all object files, then
+by invoking '$(AR) $(ARFLAGS)' followed by the name of the library and
+the list of objects, and finally by calling '$(RANLIB)' on that library.
+You should call 'AC_PROG_RANLIB' from your 'configure.ac' to define
+'RANLIB' (Automake will complain otherwise).  You should also call
+'AM_PROG_AR' to define 'AR', in order to support unusual archivers such
+as Microsoft lib.  'ARFLAGS' will default to 'cru'; you can override
+this variable by setting it in your 'Makefile.am' or by 'AC_SUBST'ing it
+from your 'configure.ac'.  You can override the 'AR' variable by
+defining a per-library 'maude_AR' variable (*note Program and Library
+Variables::).
+
+   Be careful when selecting library components conditionally.  Because
+building an empty library is not portable, you should ensure that any
+library always contains at least one object.
+
+   To use a static library when building a program, add it to 'LDADD'
+for this program.  In the following example, the program 'cpio' is
+statically linked with the library 'libcpio.a'.
+
+     noinst_LIBRARIES = libcpio.a
+     libcpio_a_SOURCES = ...
+
+     bin_PROGRAMS = cpio
+     cpio_SOURCES = cpio.c ...
+     cpio_LDADD = libcpio.a

+8.3 Building a Shared Library
+=============================
+
+Building shared libraries portably is a relatively complex matter.  For
+this reason, GNU Libtool (*note Introduction: (libtool)Top.) was created
+to help build shared libraries in a platform-independent way.

+
+8.3.1 The Libtool Concept
+-------------------------
+
+Libtool abstracts shared and static libraries into a unified concept
+henceforth called "libtool libraries".  Libtool libraries are files
+using the '.la' suffix, and can designate a static library, a shared
+library, or maybe both.  Their exact nature cannot be determined until
+'./configure' is run: not all platforms support all kinds of libraries,
+and users can explicitly select which libraries should be built.
+(However the package's maintainers can tune the default, *note The
+'AC_PROG_LIBTOOL' macro: (libtool)AC_PROG_LIBTOOL.)
+
+   Because object files for shared and static libraries must be compiled
+differently, libtool is also used during compilation.  Object files
+built by libtool are called "libtool objects": these are files using the
+'.lo' suffix.  Libtool libraries are built from these libtool objects.
+
+   You should not assume anything about the structure of '.la' or '.lo'
+files and how libtool constructs them: this is libtool's concern, and
+the last thing one wants is to learn about libtool's guts.  However the
+existence of these files matters, because they are used as targets and
+dependencies in 'Makefile's rules when building libtool libraries.
+There are situations where you may have to refer to these, for instance
+when expressing dependencies for building source files conditionally
+(*note Conditional Libtool Sources::).
+
+   People considering writing a plug-in system, with dynamically loaded
+modules, should look into 'libltdl': libtool's dlopening library (*note
+Using libltdl: (libtool)Using libltdl.).  This offers a portable
+dlopening facility to load libtool libraries dynamically, and can also
+achieve static linking where unavoidable.
+
+   Before we discuss how to use libtool with Automake in details, it
+should be noted that the libtool manual also has a section about how to
+use Automake with libtool (*note Using Automake with Libtool:
+(libtool)Using Automake.).

+
+8.3.2 Building Libtool Libraries
+--------------------------------
+
+Automake uses libtool to build libraries declared with the 'LTLIBRARIES'
+primary.  Each '_LTLIBRARIES' variable is a list of libtool libraries to
+build.  For instance, to create a libtool library named 'libgettext.la',
+and install it in 'libdir', write:
+
+     lib_LTLIBRARIES = libgettext.la
+     libgettext_la_SOURCES = gettext.c gettext.h ...
+
+   Automake predefines the variable 'pkglibdir', so you can use
+'pkglib_LTLIBRARIES' to install libraries in '$(libdir)/@PACKAGE@/'.
+
+   If 'gettext.h' is a public header file that needs to be installed in
+order for people to use the library, it should be declared using a
+'_HEADERS' variable, not in 'libgettext_la_SOURCES'.  Headers listed in
+the latter should be internal headers that are not part of the public
+interface.
+
+     lib_LTLIBRARIES = libgettext.la
+     libgettext_la_SOURCES = gettext.c ...
+     include_HEADERS = gettext.h ...
+
+   A package can build and install such a library along with other
+programs that use it.  This dependency should be specified using
+'LDADD'.  The following example builds a program named 'hello' that is
+linked with 'libgettext.la'.
+
+     lib_LTLIBRARIES = libgettext.la
+     libgettext_la_SOURCES = gettext.c ...
+
+     bin_PROGRAMS = hello
+     hello_SOURCES = hello.c ...
+     hello_LDADD = libgettext.la
+
+Whether 'hello' is statically or dynamically linked with 'libgettext.la'
+is not yet known: this will depend on the configuration of libtool and
+the capabilities of the host.
+

+File: automake.info,  Node: Conditional Libtool Libraries,  Next: Conditional Libtool Sources,  Prev: Libtool Libraries,  Up: A Shared Library
+
+8.3.3 Building Libtool Libraries Conditionally
+----------------------------------------------
+
+Like conditional programs (*note Conditional Programs::), there are two
+main ways to build conditional libraries: using Automake conditionals or
+using Autoconf 'AC_SUBST'itutions.
+
+   The important implementation detail you have to be aware of is that
+the place where a library will be installed matters to libtool: it needs
+to be indicated _at link-time_ using the '-rpath' option.
+
+   For libraries whose destination directory is known when Automake
+runs, Automake will automatically supply the appropriate '-rpath' option
+to libtool.  This is the case for libraries listed explicitly in some
+installable '_LTLIBRARIES' variables such as 'lib_LTLIBRARIES'.
+
+   However, for libraries determined at configure time (and thus
+mentioned in 'EXTRA_LTLIBRARIES'), Automake does not know the final
+installation directory.  For such libraries you must add the '-rpath'
+option to the appropriate '_LDFLAGS' variable by hand.
+
+   The examples below illustrate the differences between these two
+methods.
+
+   Here is an example where 'WANTEDLIBS' is an 'AC_SUBST'ed variable set
+at './configure'-time to either 'libfoo.la', 'libbar.la', both, or none.
+Although '$(WANTEDLIBS)' appears in the 'lib_LTLIBRARIES', Automake
+cannot guess it relates to 'libfoo.la' or 'libbar.la' at the time it
+creates the link rule for these two libraries.  Therefore the '-rpath'
+argument must be explicitly supplied.
+
+     EXTRA_LTLIBRARIES = libfoo.la libbar.la
+     lib_LTLIBRARIES = $(WANTEDLIBS)
+     libfoo_la_SOURCES = foo.c ...
+     libfoo_la_LDFLAGS = -rpath '$(libdir)'
+     libbar_la_SOURCES = bar.c ...
+     libbar_la_LDFLAGS = -rpath '$(libdir)'
+
+   Here is how the same 'Makefile.am' would look using Automake
+conditionals named 'WANT_LIBFOO' and 'WANT_LIBBAR'.  Now Automake is
+able to compute the '-rpath' setting itself, because it's clear that
+both libraries will end up in '$(libdir)' if they are installed.
+
+     lib_LTLIBRARIES =
+     if WANT_LIBFOO
+     lib_LTLIBRARIES += libfoo.la
+     endif
+     if WANT_LIBBAR
+     lib_LTLIBRARIES += libbar.la
+     endif
+     libfoo_la_SOURCES = foo.c ...
+     libbar_la_SOURCES = bar.c ...

+
+8.3.4 Libtool Libraries with Conditional Sources
+------------------------------------------------
+
+Conditional compilation of sources in a library can be achieved in the
+same way as conditional compilation of sources in a program (*note
+Conditional Sources::).  The only difference is that '_LIBADD' should be
+used instead of '_LDADD' and that it should mention libtool objects
+('.lo' files).
+
+   So, to mimic the 'hello' example from *note Conditional Sources::, we
+could build a 'libhello.la' library using either 'hello-linux.c' or
+'hello-generic.c' with the following 'Makefile.am'.
+
+     lib_LTLIBRARIES = libhello.la
+     libhello_la_SOURCES = hello-common.c
+     EXTRA_libhello_la_SOURCES = hello-linux.c hello-generic.c
+     libhello_la_LIBADD = $(HELLO_SYSTEM)
+     libhello_la_DEPENDENCIES = $(HELLO_SYSTEM)
+
+And make sure 'configure' defines 'HELLO_SYSTEM' as either
+'hello-linux.lo' or 'hello-generic.lo'.
+
+   Or we could simply use an Automake conditional as follows.
+
+     lib_LTLIBRARIES = libhello.la
+     libhello_la_SOURCES = hello-common.c
+     if LINUX
+     libhello_la_SOURCES += hello-linux.c
+     else
+     libhello_la_SOURCES += hello-generic.c
+     endif

+
+8.3.5 Libtool Convenience Libraries
+-----------------------------------
+
+Sometimes you want to build libtool libraries that should not be
+installed.  These are called "libtool convenience libraries" and are
+typically used to encapsulate many sublibraries, later gathered into one
+big installed library.
+
+   Libtool convenience libraries are declared by directory-less
+variables such as 'noinst_LTLIBRARIES', 'check_LTLIBRARIES', or even
+'EXTRA_LTLIBRARIES'.  Unlike installed libtool libraries they do not
+need an '-rpath' flag at link time (actually this is the only
+difference).
+
+   Convenience libraries listed in 'noinst_LTLIBRARIES' are always
+built.  Those listed in 'check_LTLIBRARIES' are built only upon 'make
+check'.  Finally, libraries listed in 'EXTRA_LTLIBRARIES' are never
+built explicitly: Automake outputs rules to build them, but if the
+library does not appear as a Makefile dependency anywhere it won't be
+built (this is why 'EXTRA_LTLIBRARIES' is used for conditional
+compilation).
+
+   Here is a sample setup merging libtool convenience libraries from
+subdirectories into one main 'libtop.la' library.
+
+     # -- Top-level Makefile.am --
+     SUBDIRS = sub1 sub2 ...
+     lib_LTLIBRARIES = libtop.la
+     libtop_la_SOURCES =
+     libtop_la_LIBADD = \
+       sub1/libsub1.la \
+       sub2/libsub2.la \
+       ...
+
+     # -- sub1/Makefile.am --
+     noinst_LTLIBRARIES = libsub1.la
+     libsub1_la_SOURCES = ...
+
+     # -- sub2/Makefile.am --
+     # showing nested convenience libraries
+     SUBDIRS = sub2.1 sub2.2 ...
+     noinst_LTLIBRARIES = libsub2.la
+     libsub2_la_SOURCES =
+     libsub2_la_LIBADD = \
+       sub21/libsub21.la \
+       sub22/libsub22.la \
+       ...
+
+   When using such setup, beware that 'automake' will assume 'libtop.la'
+is to be linked with the C linker.  This is because 'libtop_la_SOURCES'
+is empty, so 'automake' picks C as default language.  If
+'libtop_la_SOURCES' was not empty, 'automake' would select the linker as
+explained in *note How the Linker is Chosen::.
+
+   If one of the sublibraries contains non-C source, it is important
+that the appropriate linker be chosen.  One way to achieve this is to
+pretend that there is such a non-C file among the sources of the
+library, thus forcing 'automake' to select the appropriate linker.  Here
+is the top-level 'Makefile' of our example updated to force C++ linking.
+
+     SUBDIRS = sub1 sub2 ...
+     lib_LTLIBRARIES = libtop.la
+     libtop_la_SOURCES =
+     # Dummy C++ source to cause C++ linking.
+     nodist_EXTRA_libtop_la_SOURCES = dummy.cxx
+     libtop_la_LIBADD = \
+       sub1/libsub1.la \
+       sub2/libsub2.la \
+       ...
+
+   'EXTRA_*_SOURCES' variables are used to keep track of source files
+that might be compiled (this is mostly useful when doing conditional
+compilation using 'AC_SUBST', *note Conditional Libtool Sources::), and
+the 'nodist_' prefix means the listed sources are not to be distributed
+(*note Program and Library Variables::).  In effect the file 'dummy.cxx'
+does not need to exist in the source tree.  Of course if you have some
+real source file to list in 'libtop_la_SOURCES' there is no point in
+cheating with 'nodist_EXTRA_libtop_la_SOURCES'.

+
+8.3.6 Libtool Modules
+---------------------
+
+These are libtool libraries meant to be dlopened.  They are indicated to
+libtool by passing '-module' at link-time.
+
+     pkglib_LTLIBRARIES = mymodule.la
+     mymodule_la_SOURCES = doit.c
+     mymodule_la_LDFLAGS = -module
+
+   Ordinarily, Automake requires that a library's name start with 'lib'.
+However, when building a dynamically loadable module you might wish to
+use a "nonstandard" name.  Automake will not complain about such
+nonstandard names if it knows the library being built is a libtool
+module, i.e., if '-module' explicitly appears in the library's
+'_LDFLAGS' variable (or in the common 'AM_LDFLAGS' variable when no
+per-library '_LDFLAGS' variable is defined).
+
+   As always, 'AC_SUBST' variables are black boxes to Automake since
+their values are not yet known when 'automake' is run.  Therefore if
+'-module' is set via such a variable, Automake cannot notice it and will
+proceed as if the library was an ordinary libtool library, with strict
+naming.
+
+   If 'mymodule_la_SOURCES' is not specified, then it defaults to the
+single file 'mymodule.c' (*note Default _SOURCES::).

+
+8.3.7 '_LIBADD', '_LDFLAGS', and '_LIBTOOLFLAGS'
+------------------------------------------------
+
+As shown in previous sections, the 'LIBRARY_LIBADD' variable should be
+used to list extra libtool objects ('.lo' files) or libtool libraries
+('.la') to add to LIBRARY.
+
+   The 'LIBRARY_LDFLAGS' variable is the place to list additional
+libtool linking flags, such as '-version-info', '-static', and a lot
+more.  *Note Link mode: (libtool)Link mode.
+
+   The 'libtool' command has two kinds of options: mode-specific options
+and generic options.  Mode-specific options such as the aforementioned
+linking flags should be lumped with the other flags passed to the tool
+invoked by 'libtool' (hence the use of 'LIBRARY_LDFLAGS' for libtool
+linking flags).  Generic options include '--tag=TAG' and '--silent'
+(*note Invoking 'libtool': (libtool)Invoking libtool. for more options)
+should appear before the mode selection on the command line; in
+'Makefile.am's they should be listed in the 'LIBRARY_LIBTOOLFLAGS'
+variable.
+
+   If 'LIBRARY_LIBTOOLFLAGS' is not defined, then the variable
+'AM_LIBTOOLFLAGS' is used instead.
+
+   These flags are passed to libtool after the '--tag=TAG' option
+computed by Automake (if any), so 'LIBRARY_LIBTOOLFLAGS' (or
+'AM_LIBTOOLFLAGS') is a good place to override or supplement the
+'--tag=TAG' setting.
+
+   The libtool rules also use a 'LIBTOOLFLAGS' variable that should not
+be set in 'Makefile.am': this is a user variable (*note Flag Variables
+Ordering::.  It allows users to run 'make LIBTOOLFLAGS=--silent', for
+instance.  Note that the verbosity of 'libtool' can also be influenced
+by the Automake support for silent rules (*note Automake Silent
+Rules::).

+8.3.8 'LTLIBOBJS' and 'LTALLOCA'
+--------------------------------
+
+Where an ordinary library might include '$(LIBOBJS)' or '$(ALLOCA)'
+(*note LIBOBJS::), a libtool library must use '$(LTLIBOBJS)' or
+'$(LTALLOCA)'.  This is required because the object files that libtool
+operates on do not necessarily end in '.o'.
+
+   Nowadays, the computation of 'LTLIBOBJS' from 'LIBOBJS' is performed
+automatically by Autoconf (*note 'AC_LIBOBJ' vs. 'LIBOBJS':

+8.3.9.1 Error: 'required file `./ltmain.sh' not found'
+......................................................
+
+Libtool comes with a tool called 'libtoolize' that will install
+libtool's supporting files into a package.  Running this command will
+install 'ltmain.sh'.  You should execute it before 'aclocal' and
+'automake'.
+
+   People upgrading old packages to newer autotools are likely to face
+this issue because older Automake versions used to call 'libtoolize'.
+Therefore old build scripts do not call 'libtoolize'.
+
+   Since Automake 1.6, it has been decided that running 'libtoolize' was
+none of Automake's business.  Instead, that functionality has been moved
+into the 'autoreconf' command (*note Using 'autoreconf':
+(autoconf)autoreconf Invocation.).  If you do not want to remember what
+to run and when, just learn the 'autoreconf' command.  Hopefully,
+replacing existing 'bootstrap.sh' or 'autogen.sh' scripts by a call to
+'autoreconf' should also free you from any similar incompatible change
+in the future.

+8.3.9.2 Objects 'created with both libtool and without'
+.......................................................
+
+Sometimes, the same source file is used both to build a libtool library
+and to build another non-libtool target (be it a program or another
+library).
+
+   Let's consider the following 'Makefile.am'.
+
+     bin_PROGRAMS = prog
+     prog_SOURCES = prog.c foo.c ...
+
+     lib_LTLIBRARIES = libfoo.la
+     libfoo_la_SOURCES = foo.c ...
+
+(In this trivial case the issue could be avoided by linking 'libfoo.la'
+with 'prog' instead of listing 'foo.c' in 'prog_SOURCES'.  But let's
+assume we really want to keep 'prog' and 'libfoo.la' separate.)
+
+   Technically, it means that we should build 'foo.$(OBJEXT)' for
+'prog', and 'foo.lo' for 'libfoo.la'.  The problem is that in the course
+of creating 'foo.lo', libtool may erase (or replace) 'foo.$(OBJEXT)',
+and this cannot be avoided.
+
+   Therefore, when Automake detects this situation it will complain with
+a message such as
+     object 'foo.$(OBJEXT)' created both with libtool and without
+
+   A workaround for this issue is to ensure that these two objects get
+different basenames.  As explained in *note Renamed Objects::, this
+happens automatically when per-targets flags are used.
+
+     bin_PROGRAMS = prog
+     prog_SOURCES = prog.c foo.c ...
+     prog_CFLAGS = $(AM_CFLAGS)
+
+     lib_LTLIBRARIES = libfoo.la
+     libfoo_la_SOURCES = foo.c ...
+
+Adding 'prog_CFLAGS = $(AM_CFLAGS)' is almost a no-op, because when the
+'prog_CFLAGS' is defined, it is used instead of 'AM_CFLAGS'.  However as
+a side effect it will cause 'prog.c' and 'foo.c' to be compiled as
+'prog-prog.$(OBJEXT)' and 'prog-foo.$(OBJEXT)', which solves the issue.

+
+8.4 Program and Library Variables
+=================================
+
+Associated with each program is a collection of variables that can be
+used to modify how that program is built.  There is a similar list of
+such variables for each library.  The canonical name of the program (or
+library) is used as a base for naming these variables.
+
+   In the list below, we use the name "maude" to refer to the program or
+library.  In your 'Makefile.am' you would replace this with the
+canonical name of your program.  This list also refers to "maude" as a
+program, but in general the same rules apply for both static and dynamic
+libraries; the documentation below notes situations where programs and
+libraries differ.
+
+'maude_SOURCES'
+     This variable, if it exists, lists all the source files that are
+     compiled to build the program.  These files are added to the
+     distribution by default.  When building the program, Automake will
+     cause each source file to be compiled to a single '.o' file (or
+     '.lo' when using libtool).  Normally these object files are named
+     after the source file, but other factors can change this.  If a
+     file in the '_SOURCES' variable has an unrecognized extension,
+     Automake will do one of two things with it.  If a suffix rule
+     exists for turning files with the unrecognized extension into '.o'
+     files, then 'automake' will treat this file as it will any other
+     source file (*note Support for Other Languages::).  Otherwise, the
+     file will be ignored as though it were a header file.
+
+     The prefixes 'dist_' and 'nodist_' can be used to control whether
+     files listed in a '_SOURCES' variable are distributed.  'dist_' is
+     redundant, as sources are distributed by default, but it can be
+     specified for clarity if desired.
+
+     It is possible to have both 'dist_' and 'nodist_' variants of a
+     given '_SOURCES' variable at once; this lets you easily distribute
+     some files and not others, for instance:
+
+          nodist_maude_SOURCES = nodist.c
+          dist_maude_SOURCES = dist-me.c
+
+     By default the output file (on Unix systems, the '.o' file) will be
+     put into the current build directory.  However, if the option
+     'subdir-objects' is in effect in the current directory then the
+     '.o' file will be put into the subdirectory named after the source
+     file.  For instance, with 'subdir-objects' enabled,
+     'sub/dir/file.c' will be compiled to 'sub/dir/file.o'.  Some people
+     prefer this mode of operation.  You can specify 'subdir-objects' in
+     'AUTOMAKE_OPTIONS' (*note Options::).
+
+'EXTRA_maude_SOURCES'
+     Automake needs to know the list of files you intend to compile
+     _statically_.  For one thing, this is the only way Automake has of
+     knowing what sort of language support a given 'Makefile.in'
+     requires.  (1) This means that, for example, you can't put a
+     configure substitution like '@my_sources@' into a '_SOURCES'
+     variable.  If you intend to conditionally compile source files and
+     use 'configure' to substitute the appropriate object names into,
+     e.g., '_LDADD' (see below), then you should list the corresponding
+     source files in the 'EXTRA_' variable.
+
+     This variable also supports 'dist_' and 'nodist_' prefixes.  For
+     instance, 'nodist_EXTRA_maude_SOURCES' would list extra sources
+     that may need to be built, but should not be distributed.
+
+'maude_AR'
+     A static library is created by default by invoking '$(AR)
+     $(ARFLAGS)' followed by the name of the library and then the
+     objects being put into the library.  You can override this by
+     setting the '_AR' variable.  This is usually used with C++; some
+     C++ compilers require a special invocation in order to instantiate
+     all the templates that should go into a library.  For instance, the
+     SGI C++ compiler likes this variable set like so:
+          libmaude_a_AR = $(CXX) -ar -o
+
+'maude_LIBADD'
+     Extra objects can be added to a _library_ using the '_LIBADD'
+     variable.  For instance, this should be used for objects determined
+     by 'configure' (*note A Library::).
+
+     In the case of libtool libraries, 'maude_LIBADD' can also refer to
+     other libtool libraries.
+
+'maude_LDADD'
+     Extra objects ('*.$(OBJEXT)') and libraries ('*.a', '*.la') can be
+     added to a _program_ by listing them in the '_LDADD' variable.  For
+     instance, this should be used for objects determined by 'configure'
+     (*note Linking::).
+
+     '_LDADD' and '_LIBADD' are inappropriate for passing
+     program-specific linker flags (except for '-l', '-L', '-dlopen' and
+     '-dlpreopen').  Use the '_LDFLAGS' variable for this purpose.
+
+     For instance, if your 'configure.ac' uses 'AC_PATH_XTRA', you could
+     link your program against the X libraries like so:
+
+          maude_LDADD = $(X_PRE_LIBS) $(X_LIBS) $(X_EXTRA_LIBS)
+
+     We recommend that you use '-l' and '-L' only when referring to
+     third-party libraries, and give the explicit file names of any
+     library built by your package.  Doing so will ensure that
+     'maude_DEPENDENCIES' (see below) is correctly defined by default.
+
+'maude_LDFLAGS'
+     This variable is used to pass extra flags to the link step of a
+     program or a shared library.  It overrides the 'AM_LDFLAGS'
+     variable.
+
+'maude_LIBTOOLFLAGS'
+     This variable is used to pass extra options to 'libtool'.  It
+     overrides the 'AM_LIBTOOLFLAGS' variable.  These options are output
+     before 'libtool''s '--mode=MODE' option, so they should not be
+     mode-specific options (those belong to the compiler or linker
+     flags).  *Note Libtool Flags::.
+
+'maude_DEPENDENCIES'
+'EXTRA_maude_DEPENDENCIES'
+     It is also occasionally useful to have a target (program or
+     library) depend on some other file that is not actually part of
+     that target.  This can be done using the '_DEPENDENCIES' variable.
+     Each target depends on the contents of such a variable, but no
+     further interpretation is done.
+
+     Since these dependencies are associated to the link rule used to
+     create the programs they should normally list files used by the
+     link command.  That is '*.$(OBJEXT)', '*.a', or '*.la' files for
+     programs; '*.lo' and '*.la' files for Libtool libraries; and
+     '*.$(OBJEXT)' files for static libraries.  In rare cases you may
+     need to add other kinds of files such as linker scripts, but
+     _listing a source file in '_DEPENDENCIES' is wrong_.  If some
+     source file needs to be built before all the components of a
+     program are built, consider using the 'BUILT_SOURCES' variable
+     (*note Sources::).
+
+     If '_DEPENDENCIES' is not supplied, it is computed by Automake.
+     The automatically-assigned value is the contents of '_LDADD' or
+     '_LIBADD', with most configure substitutions, '-l', '-L', '-dlopen'
+     and '-dlpreopen' options removed.  The configure substitutions that
+     are left in are only '$(LIBOBJS)' and '$(ALLOCA)'; these are left
+     because it is known that they will not cause an invalid value for
+     '_DEPENDENCIES' to be generated.
+
+     '_DEPENDENCIES' is more likely used to perform conditional
+     compilation using an 'AC_SUBST' variable that contains a list of
+     objects.  *Note Conditional Sources::, and *note Conditional
+     Libtool Sources::.
+
+     The 'EXTRA_*_DEPENDENCIES' variable may be useful for cases where
+     you merely want to augment the 'automake'-generated '_DEPENDENCIES'
+     variable rather than replacing it.
+
+'maude_LINK'
+     You can override the linker on a per-program basis.  By default the
+     linker is chosen according to the languages used by the program.
+     For instance, a program that includes C++ source code would use the
+     C++ compiler to link.  The '_LINK' variable must hold the name of a
+     command that can be passed all the '.o' file names and libraries to
+     link against as arguments.  Note that the name of the underlying
+     program is _not_ passed to '_LINK'; typically one uses '$@':
+
+          maude_LINK = $(CCLD) -magic -o $@
+
+     If a '_LINK' variable is not supplied, it may still be generated
+     and used by Automake due to the use of per-target link flags such
+     as '_CFLAGS', '_LDFLAGS' or '_LIBTOOLFLAGS', in cases where they
+     apply.
+
+'maude_CCASFLAGS'
+'maude_CFLAGS'
+'maude_CPPFLAGS'
+'maude_CXXFLAGS'
+'maude_FFLAGS'
+'maude_GCJFLAGS'
+'maude_LFLAGS'
+'maude_OBJCFLAGS'
+'maude_OBJCXXFLAGS'
+'maude_RFLAGS'
+'maude_UPCFLAGS'
+'maude_YFLAGS'
+     Automake allows you to set compilation flags on a per-program (or
+     per-library) basis.  A single source file can be included in
+     several programs, and it will potentially be compiled with
+     different flags for each program.  This works for any language
+     directly supported by Automake.  These "per-target compilation
+     flags" are '_CCASFLAGS', '_CFLAGS', '_CPPFLAGS', '_CXXFLAGS',
+     '_FFLAGS', '_GCJFLAGS', '_LFLAGS', '_OBJCFLAGS', '_OBJCXXFLAGS',
+     '_RFLAGS', '_UPCFLAGS', and '_YFLAGS'.
+
+     When using a per-target compilation flag, Automake will choose a
+     different name for the intermediate object files.  Ordinarily a
+     file like 'sample.c' will be compiled to produce 'sample.o'.
+     However, if the program's '_CFLAGS' variable is set, then the
+     object file will be named, for instance, 'maude-sample.o'.  (See
+     also *note Renamed Objects::).
+
+     In compilations with per-target flags, the ordinary 'AM_' form of
+     the flags variable is _not_ automatically included in the
+     compilation (however, the user form of the variable _is_ included).
+     So for instance, if you want the hypothetical 'maude' compilations
+     to also use the value of 'AM_CFLAGS', you would need to write:
+
+          maude_CFLAGS = ... your flags ... $(AM_CFLAGS)
+
+     *Note Flag Variables Ordering::, for more discussion about the
+     interaction between user variables, 'AM_' shadow variables, and
+     per-target variables.
+
+'maude_SHORTNAME'
+     On some platforms the allowable file names are very short.  In
+     order to support these systems and per-target compilation flags at
+     the same time, Automake allows you to set a "short name" that will
+     influence how intermediate object files are named.  For instance,
+     in the following example,
+
+          bin_PROGRAMS = maude
+          maude_CPPFLAGS = -DSOMEFLAG
+          maude_SHORTNAME = m
+          maude_SOURCES = sample.c ...
+
+     the object file would be named 'm-sample.o' rather than
+     'maude-sample.o'.
+
+     This facility is rarely needed in practice, and we recommend
+     avoiding it until you find it is required.

+
+8.5 Default '_SOURCES'
+======================
+
+'_SOURCES' variables are used to specify source files of programs (*note
+A Program::), libraries (*note A Library::), and Libtool libraries
+(*note A Shared Library::).
+
+   When no such variable is specified for a target, Automake will define
+one itself.  The default is to compile a single C file whose base name
+is the name of the target itself, with any extension replaced by
+'AM_DEFAULT_SOURCE_EXT', which defaults to '.c'.
+
+   For example if you have the following somewhere in your 'Makefile.am'
+with no corresponding 'libfoo_a_SOURCES':
+
+     lib_LIBRARIES = libfoo.a sub/libc++.a
+
+'libfoo.a' will be built using a default source file named 'libfoo.c',
+and 'sub/libc++.a' will be built from 'sub/libc++.c'.  (In older
+versions 'sub/libc++.a' would be built from 'sub_libc___a.c', i.e., the
+default source was the canonized name of the target, with '.c' appended.
+We believe the new behavior is more sensible, but for backward
+compatibility 'automake' will use the old name if a file or a rule with
+that name exists and 'AM_DEFAULT_SOURCE_EXT' is not used.)
+
+   Default sources are mainly useful in test suites, when building many
+test programs each from a single source.  For instance, in
+
+     check_PROGRAMS = test1 test2 test3
+     AM_DEFAULT_SOURCE_EXT = .cpp
+
+'test1', 'test2', and 'test3' will be built from 'test1.cpp',
+'test2.cpp', and 'test3.cpp'.  Without the last line, they will be built
+from 'test1.c', 'test2.c', and 'test3.c'.
+
+   Another case where this is convenient is building many Libtool
+modules ('moduleN.la'), each defined in its own file ('moduleN.c').
+
+     AM_LDFLAGS = -module
+     lib_LTLIBRARIES = module1.la module2.la module3.la
+
+   Finally, there is one situation where this default source computation
+needs to be avoided: when a target should not be built from sources.  We
+already saw such an example in *note true::; this happens when all the
+constituents of a target have already been compiled and just need to be
+combined using a '_LDADD' variable.  Then it is necessary to define an
+empty '_SOURCES' variable, so that 'automake' does not compute a
+default.
+
+     bin_PROGRAMS = target
+     target_SOURCES =
+     target_LDADD = libmain.a libmisc.a

+
+8.6 Special handling for 'LIBOBJS' and 'ALLOCA'
+===============================================
+
+The '$(LIBOBJS)' and '$(ALLOCA)' variables list object files that should
+be compiled into the project to provide an implementation for functions
+that are missing or broken on the host system.  They are substituted by
+'configure'.
+
+   These variables are defined by Autoconf macros such as 'AC_LIBOBJ',
+'AC_REPLACE_FUNCS' (*note Generic Function Checks: (autoconf)Generic
+Functions.), or 'AC_FUNC_ALLOCA' (*note Particular Function Checks:
+(autoconf)Particular Functions.).  Many other Autoconf macros call
+'AC_LIBOBJ' or 'AC_REPLACE_FUNCS' to populate '$(LIBOBJS)'.
+
+   Using these variables is very similar to doing conditional
+compilation using 'AC_SUBST' variables, as described in *note
+Conditional Sources::.  That is, when building a program, '$(LIBOBJS)'
+and '$(ALLOCA)' should be added to the associated '*_LDADD' variable, or
+to the '*_LIBADD' variable when building a library.  However there is no
+need to list the corresponding sources in 'EXTRA_*_SOURCES' nor to
+define '*_DEPENDENCIES'.  Automake automatically adds '$(LIBOBJS)' and
+'$(ALLOCA)' to the dependencies, and it will discover the list of
+corresponding source files automatically (by tracing the invocations of
+the 'AC_LIBSOURCE' Autoconf macros).  If you have already defined
+'*_DEPENDENCIES' explicitly for an unrelated reason, then you either
+need to add these variables manually, or use 'EXTRA_*_DEPENDENCIES'
+instead of '*_DEPENDENCIES'.
+
+   These variables are usually used to build a portability library that
+is linked with all the programs of the project.  We now review a sample
+setup.  First, 'configure.ac' contains some checks that affect either
+'LIBOBJS' or 'ALLOCA'.
+
+     # configure.ac
+     ...
+     AC_CONFIG_LIBOBJ_DIR([lib])
+     ...
+     AC_FUNC_MALLOC             dnl May add malloc.$(OBJEXT) to LIBOBJS
+     AC_FUNC_MEMCMP             dnl May add memcmp.$(OBJEXT) to LIBOBJS
+     AC_REPLACE_FUNCS([strdup]) dnl May add strdup.$(OBJEXT) to LIBOBJS
+     AC_FUNC_ALLOCA             dnl May add alloca.$(OBJEXT) to ALLOCA
+     ...
+     AC_CONFIG_FILES([
+       lib/Makefile
+       src/Makefile
+     ])
+     AC_OUTPUT
+
+   The 'AC_CONFIG_LIBOBJ_DIR' tells Autoconf that the source files of
+these object files are to be found in the 'lib/' directory.  Automake
+can also use this information, otherwise it expects the source files are
+to be in the directory where the '$(LIBOBJS)' and '$(ALLOCA)' variables
+are used.
+
+   The 'lib/' directory should therefore contain 'malloc.c', 'memcmp.c',
+'strdup.c', 'alloca.c'.  Here is its 'Makefile.am':
+
+     # lib/Makefile.am
+
+     noinst_LIBRARIES = libcompat.a
+     libcompat_a_SOURCES =
+     libcompat_a_LIBADD = $(LIBOBJS) $(ALLOCA)
+
+   The library can have any name, of course, and anyway it is not going
+to be installed: it just holds the replacement versions of the missing
+or broken functions so we can later link them in.  Many projects also
+include extra functions, specific to the project, in that library: they
+are simply added on the '_SOURCES' line.
+
+   There is a small trap here, though: '$(LIBOBJS)' and '$(ALLOCA)'
+might be empty, and building an empty library is not portable.  You
+should ensure that there is always something to put in 'libcompat.a'.
+Most projects will also add some utility functions in that directory,
+and list them in 'libcompat_a_SOURCES', so in practice 'libcompat.a'
+cannot be empty.
+
+   Finally here is how this library could be used from the 'src/'
+directory.
+
+     # src/Makefile.am
+
+     # Link all programs in this directory with libcompat.a
+     LDADD = ../lib/libcompat.a
+
+     bin_PROGRAMS = tool1 tool2 ...
+     tool1_SOURCES = ...
+     tool2_SOURCES = ...
+
+   When option 'subdir-objects' is not used, as in the above example,
+the variables '$(LIBOBJS)' or '$(ALLOCA)' can only be used in the
+directory where their sources lie.  E.g., here it would be wrong to use
+'$(LIBOBJS)' or '$(ALLOCA)' in 'src/Makefile.am'.  However if both
+'subdir-objects' and 'AC_CONFIG_LIBOBJ_DIR' are used, it is OK to use
+these variables in other directories.  For instance 'src/Makefile.am'
+could be changed as follows.
+
+     # src/Makefile.am
+
+     AUTOMAKE_OPTIONS = subdir-objects
+     LDADD = $(LIBOBJS) $(ALLOCA)
+
+     bin_PROGRAMS = tool1 tool2 ...
+     tool1_SOURCES = ...
+     tool2_SOURCES = ...
+
+   Because '$(LIBOBJS)' and '$(ALLOCA)' contain object file names that
+end with '.$(OBJEXT)', they are not suitable for Libtool libraries
+(where the expected object extension is '.lo'): 'LTLIBOBJS' and
+'LTALLOCA' should be used instead.
+
+   'LTLIBOBJS' is defined automatically by Autoconf and should not be
+defined by hand (as in the past), however at the time of writing
+'LTALLOCA' still needs to be defined from 'ALLOCA' manually.  *Note
+'AC_LIBOBJ' vs. 'LIBOBJS': (autoconf)AC_LIBOBJ vs LIBOBJS.

+File: automake.info,  Node: Program Variables,  Next: Yacc and Lex,  Prev: LIBOBJS,  Up: Programs
+
+8.7 Variables used when building a program
+==========================================
+
+Occasionally it is useful to know which 'Makefile' variables Automake
+uses for compilations, and in which order (*note Flag Variables
+Ordering::); for instance, you might need to do your own compilation in
+some special cases.
+
+   Some variables are inherited from Autoconf; these are 'CC', 'CFLAGS',
+'CPPFLAGS', 'DEFS', 'LDFLAGS', and 'LIBS'.
+
+   There are some additional variables that Automake defines on its own:
+
+'AM_CPPFLAGS'
+     The contents of this variable are passed to every compilation that
+     invokes the C preprocessor; it is a list of arguments to the
+     preprocessor.  For instance, '-I' and '-D' options should be listed
+     here.
+
+     Automake already provides some '-I' options automatically, in a
+     separate variable that is also passed to every compilation that
+     invokes the C preprocessor.  In particular it generates '-I.',
+     '-I$(srcdir)', and a '-I' pointing to the directory holding
+     'config.h' (if you've used 'AC_CONFIG_HEADERS').  You can disable
+     the default '-I' options using the 'nostdinc' option.
+
+     When a file to be included is generated during the build and not
+     part of a distribution tarball, its location is under
+     '$(builddir)', not under '$(srcdir)'.  This matters especially for
+     packages that use header files placed in sub-directories and want
+     to allow builds outside the source tree (*note VPATH Builds::).  In
+     that case we recommend to use a pair of '-I' options, such as,
+     e.g., '-Isome/subdir -I$(srcdir)/some/subdir' or
+     '-I$(top_builddir)/some/subdir -I$(top_srcdir)/some/subdir'.  Note
+     that the reference to the build tree should come before the
+     reference to the source tree, so that accidentally leftover
+     generated files in the source directory are ignored.
+
+     'AM_CPPFLAGS' is ignored in preference to a per-executable (or
+     per-library) '_CPPFLAGS' variable if it is defined.
+
+'INCLUDES'
+     This does the same job as 'AM_CPPFLAGS' (or any per-target
+     '_CPPFLAGS' variable if it is used).  It is an older name for the
+     same functionality.  This variable is deprecated; we suggest using
+     'AM_CPPFLAGS' and per-target '_CPPFLAGS' instead.
+
+'AM_CFLAGS'
+     This is the variable the 'Makefile.am' author can use to pass in
+     additional C compiler flags.  In some situations, this is not used,
+     in preference to the per-executable (or per-library) '_CFLAGS'.
+
+'COMPILE'
+     This is the command used to actually compile a C source file.  The
+     file name is appended to form the complete command line.
+
+'AM_LDFLAGS'
+     This is the variable the 'Makefile.am' author can use to pass in
+     additional linker flags.  In some situations, this is not used, in
+     preference to the per-executable (or per-library) '_LDFLAGS'.
+
+'LINK'
+     This is the command used to actually link a C program.  It already
+     includes '-o $@' and the usual variable references (for instance,
+     'CFLAGS'); it takes as "arguments" the names of the object files
+     and libraries to link in.  This variable is not used when the
+     linker is overridden with a per-target '_LINK' variable or
+     per-target flags cause Automake to define such a '_LINK' variable.
+

+File: automake.info,  Node: Yacc and Lex,  Next: C++ Support,  Prev: Program Variables,  Up: Programs
+
+8.8 Yacc and Lex support
+========================
+
+Automake has somewhat idiosyncratic support for Yacc and Lex.
+
+   Automake assumes that the '.c' file generated by 'yacc' (or 'lex')
+should be named using the basename of the input file.  That is, for a
+yacc source file 'foo.y', Automake will cause the intermediate file to
+be named 'foo.c' (as opposed to 'y.tab.c', which is more traditional).
+
+   The extension of a yacc source file is used to determine the
+extension of the resulting C or C++ source and header files.  Note that
+header files are generated only when the '-d' Yacc option is used; see
+below for more information about this flag, and how to specify it.
+Files with the extension '.y' will thus be turned into '.c' sources and
+'.h' headers; likewise, '.yy' will become '.cc' and '.hh', '.y++' will
+become 'c++' and 'h++', '.yxx' will become '.cxx' and '.hxx', and '.ypp'
+will become '.cpp' and '.hpp'.
+
+   Similarly, lex source files can be used to generate C or C++; the
+extensions '.l', '.ll', '.l++', '.lxx', and '.lpp' are recognized.
+
+   You should never explicitly mention the intermediate (C or C++) file
+in any 'SOURCES' variable; only list the source file.
+
+   The intermediate files generated by 'yacc' (or 'lex') will be
+included in any distribution that is made.  That way the user doesn't
+need to have 'yacc' or 'lex'.
+
+   If a 'yacc' source file is seen, then your 'configure.ac' must define
+the variable 'YACC'.  This is most easily done by invoking the macro
+'AC_PROG_YACC' (*note Particular Program Checks: (autoconf)Particular
+Programs.).
+
+   When 'yacc' is invoked, it is passed 'AM_YFLAGS' and 'YFLAGS'.  The
+latter is a user variable and the former is intended for the
+'Makefile.am' author.
+
+   'AM_YFLAGS' is usually used to pass the '-d' option to 'yacc'.
+Automake knows what this means and will automatically adjust its rules
+to update and distribute the header file built by 'yacc -d'(1).  What
+Automake cannot guess, though, is where this header will be used: it is
+up to you to ensure the header gets built before it is first used.
+Typically this is necessary in order for dependency tracking to work
+when the header is included by another file.  The common solution is
+listing the header file in 'BUILT_SOURCES' (*note Sources::) as follows.
+
+     BUILT_SOURCES = parser.h
+     AM_YFLAGS = -d
+     bin_PROGRAMS = foo
+     foo_SOURCES = ... parser.y ...
+
+   If a 'lex' source file is seen, then your 'configure.ac' must define
+the variable 'LEX'.  You can use 'AC_PROG_LEX' to do this (*note
+Particular Program Checks: (autoconf)Particular Programs.), but using
+'AM_PROG_LEX' macro (*note Macros::) is recommended.
+
+   When 'lex' is invoked, it is passed 'AM_LFLAGS' and 'LFLAGS'.  The
+latter is a user variable and the former is intended for the
+'Makefile.am' author.
+
+   When 'AM_MAINTAINER_MODE' (*note maintainer-mode::) is used, the
+rebuild rule for distributed Yacc and Lex sources are only used when
+'maintainer-mode' is enabled, or when the files have been erased.
+
+   When 'lex' or 'yacc' sources are used, 'automake -a' automatically
+installs an auxiliary program called 'ylwrap' in your package (*note
+Auxiliary Programs::).  This program is used by the build rules to
+rename the output of these tools, and makes it possible to include
+multiple 'yacc' (or 'lex') source files in a single directory.  (This is
+necessary because yacc's output file name is fixed, and a parallel make
+could conceivably invoke more than one instance of 'yacc'
+simultaneously.)
+
+   For 'yacc', simply managing locking is insufficient.  The output of
+'yacc' always uses the same symbol names internally, so it isn't
+possible to link two 'yacc' parsers into the same executable.
+
+   We recommend using the following renaming hack used in 'gdb':
+     #define yymaxdepth c_maxdepth
+     #define yyparse c_parse

+
+   The variable 'CCAS' holds the name of the compiler used to build

+
+   The autoconf macro 'AM_PROG_AS' will define 'CCAS' and 'CCASFLAGS'
+for you (unless they are already set, it simply sets 'CCAS' to the C

+8.14.3 Mixing Fortran 77 With C and C++
+---------------------------------------
+
+Automake currently provides _limited_ support for creating programs and
+shared libraries that are a mixture of Fortran 77 and C and/or C++.
+However, there are many other issues related to mixing Fortran 77 with
+other languages that are _not_ (currently) handled by Automake, but that
+are handled by other packages(1).
+
+   Automake can help in two ways:
+
+  1. Automatic selection of the linker depending on which combinations
+     of source code.
+
+  2. Automatic selection of the appropriate linker flags (e.g., '-L' and
+     '-l') to pass to the automatically selected linker in order to link
+     in the appropriate Fortran 77 intrinsic and run-time libraries.
+
+     These extra Fortran 77 linker flags are supplied in the output
+     variable 'FLIBS' by the 'AC_F77_LIBRARY_LDFLAGS' Autoconf macro.
+     *Note Fortran Compiler Characteristics: (autoconf)Fortran Compiler.
+
+   If Automake detects that a program or shared library (as mentioned in
+some '_PROGRAMS' or '_LTLIBRARIES' primary) contains source code that is
+a mixture of Fortran 77 and C and/or C++, then it requires that the
+macro 'AC_F77_LIBRARY_LDFLAGS' be called in 'configure.ac', and that
+either '$(FLIBS)' appear in the appropriate '_LDADD' (for programs) or
+'_LIBADD' (for shared libraries) variables.  It is the responsibility of
+the person writing the 'Makefile.am' to make sure that '$(FLIBS)'
+appears in the appropriate '_LDADD' or '_LIBADD' variable.
+
+   For example, consider the following 'Makefile.am':
+
+     bin_PROGRAMS = foo
+     foo_SOURCES  = main.cc foo.f
+     foo_LDADD    = libfoo.la $(FLIBS)
+
+     pkglib_LTLIBRARIES = libfoo.la
+     libfoo_la_SOURCES  = bar.f baz.c zardoz.cc
+     libfoo_la_LIBADD   = $(FLIBS)
+
+   In this case, Automake will insist that 'AC_F77_LIBRARY_LDFLAGS' is
+mentioned in 'configure.ac'.  Also, if '$(FLIBS)' hadn't been mentioned
+in 'foo_LDADD' and 'libfoo_la_LIBADD', then Automake would have issued a
+warning.

+(http://www-zeus.desy.de/~burow/cfortran/) addresses all of these
+inter-language issues, and runs under nearly all Fortran 77, C and C++

+File: automake.info,  Node: How the Linker is Chosen,  Up: Mixing Fortran 77 With C and C++
+
+8.14.3.1 How the Linker is Chosen
+.................................
+
+When a program or library mixes several languages, Automake choose the
+linker according to the following priorities.  (The names in parentheses
+are the variables containing the link command.)
+
+  1. Native Java ('GCJLINK')
+  2. Objective C++ ('OBJCXXLINK')
+  3. C++ ('CXXLINK')
+  4. Fortran 77 ('F77LINK')
+  5. Fortran ('FCLINK')
+  6. Objective C ('OBJCLINK')
+  7. Unified Parallel C ('UPCLINK')
+  8. C ('LINK')
+
+   For example, if Fortran 77, C and C++ source code is compiled into a
+program, then the C++ linker will be used.  In this case, if the C or
+Fortran 77 linkers required any special libraries that weren't included
+by the C++ linker, then they must be manually added to an '_LDADD' or
+'_LIBADD' variable by the user writing the 'Makefile.am'.
+
+   Automake only looks at the file names listed in '_SOURCES' variables
+to choose the linker, and defaults to the C linker.  Sometimes this is
+inconvenient because you are linking against a library written in
+another language and would like to set the linker more appropriately.
+*Note Libtool Convenience Libraries::, for a trick with
+'nodist_EXTRA_..._SOURCES'.
+
+   A per-target '_LINK' variable will override the above selection.
+Per-target link flags will cause Automake to write a per-target '_LINK'
+variable according to the language chosen as above.

+8.16 Compiling Java sources using gcj
+=====================================
+
+Automake includes support for natively compiled Java, using 'gcj', the
+Java front end to the GNU Compiler Collection (rudimentary support for
+compiling Java to bytecode using the 'javac' compiler is also present,
+_albeit deprecated_; *note Java::).
+
+   Any package including Java code to be compiled must define the output
+variable 'GCJ' in 'configure.ac'; the variable 'GCJFLAGS' must also be
+defined somehow (either in 'configure.ac' or 'Makefile.am').  The
+simplest way to do this is to use the 'AM_PROG_GCJ' macro.
+
+   By default, programs including Java source files are linked with
+'gcj'.
+
+   As always, the contents of 'AM_GCJFLAGS' are passed to every
+compilation invoking 'gcj' (in its role as an ahead-of-time compiler,
+when invoking it to create '.class' files, 'AM_JAVACFLAGS' is used
+instead).  If it is necessary to pass options to 'gcj' from
+'Makefile.am', this variable, and not the user variable 'GCJFLAGS',
+should be used.
+
+   'gcj' can be used to compile '.java', '.class', '.zip', or '.jar'
+files.
+
+   When linking, 'gcj' requires that the main class be specified using
+the '--main=' option.  The easiest way to do this is to use the
+'_LDFLAGS' variable for the program.
+
+
+File: automake.info,  Node: Vala Support,  Next: Support for Other Languages,  Prev: Java Support with gcj,  Up: Programs
+
+8.17 Vala Support
+=================
+
+Automake provides initial support for Vala
+(<http://www.vala-project.org/>).  This requires valac version 0.7.0 or
+later, and currently requires the user to use GNU 'make'.
+
+     foo_SOURCES = foo.vala bar.vala zardoc.c
+
+   Any '.vala' file listed in a '_SOURCES' variable will be compiled
+into C code by the Vala compiler.  The generated '.c' files are
+distributed.  The end user does not need to have a Vala compiler
+installed.
+
+   Automake ships with an Autoconf macro called 'AM_PROG_VALAC' that
+will locate the Vala compiler and optionally check its version number.
+
+ -- Macro: AM_PROG_VALAC ([MINIMUM-VERSION], [ACTION-IF-FOUND],
+     [ACTION-IF-NOT-FOUND]) Search for a Vala compiler in 'PATH'.  If it
+     is found, the variable 'VALAC' is set to point to it (see below for
+     more details).  This macro takes three optional arguments.  The
+     first argument, if present, is the minimum version of the Vala
+     compiler required to compile this package.  If a compiler is found
+     and satisfies MINIMUM-VERSION, then ACTION-IF-FOUND is run (this
+     defaults to do nothing).  Otherwise, ACTION-IF-NOT-FOUND is run.
+     If ACTION-IF-NOT-FOUND is not specified, the default value is to
+     print a warning in case no compiler is found, or if a too-old
+     version of the compiler is found.
+
+   There are a few variables that are used when compiling Vala sources:
+
+'VALAC'
+     Absolute path to the Vala compiler, or simply 'valac' if no
+     suitable compiler Vala could be found at configure runtime.
+
+'VALAFLAGS'
+     Additional arguments for the Vala compiler.
+
+'AM_VALAFLAGS'
+     The maintainer's variant of 'VALAFLAGS'.
+
+          lib_LTLIBRARIES = libfoo.la
+          libfoo_la_SOURCES = foo.vala
+
+   Note that currently, you cannot use per-target '*_VALAFLAGS' (*note
+Renamed Objects::) to produce different C files from one Vala source
+file.

+8.18 Support for Other Languages
+================================
+
+Automake currently only includes full support for C, C++ (*note C++
+Support::), Objective C (*note Objective C Support::), Objective C++
+(*note Objective C++ Support::), Fortran 77 (*note Fortran 77
+Support::), Fortran 9x (*note Fortran 9x Support::), and Java (*note
+Java Support with gcj::).  There is only rudimentary support for other
+languages, support for which will be improved based on user demand.
+
+   Some limited support for adding your own languages is available via
+the suffix rule handling (*note Suffixes::).

+
+8.19 Automatic dependency tracking
+==================================
+
+As a developer it is often painful to continually update the
+'Makefile.am' whenever the include-file dependencies change in a
+project.  Automake supplies a way to automatically track dependency
+changes (*note Dependency Tracking::).
+
+   Automake always uses complete dependencies for a compilation,
+including system headers.  Automake's model is that dependency
+computation should be a side effect of the build.  To this end,
+dependencies are computed by running all compilations through a special
+wrapper program called 'depcomp'.  'depcomp' understands how to coax
+many different C and C++ compilers into generating dependency
+information in the format it requires.  'automake -a' will install
+'depcomp' into your source tree for you.  If 'depcomp' can't figure out
+how to properly invoke your compiler, dependency tracking will simply be
+disabled for your build.
+
+   Experience with earlier versions of Automake (*note Dependency
+Tracking Evolution: (automake-history)Dependency Tracking Evolution.)
+taught us that it is not reliable to generate dependencies only on the
+maintainer's system, as configurations vary too much.  So instead
+Automake implements dependency tracking at build time.
+
+   Automatic dependency tracking can be suppressed by putting
+'no-dependencies' in the variable 'AUTOMAKE_OPTIONS', or passing
+'no-dependencies' as an argument to 'AM_INIT_AUTOMAKE' (this should be
+the preferred way).  Or, you can invoke 'automake' with the '-i' option.
+Dependency tracking is enabled by default.
+
+   The person building your package also can choose to disable
+dependency tracking by configuring with '--disable-dependency-tracking'.
+
+
+File: automake.info,  Node: EXEEXT,  Prev: Dependencies,  Up: Programs
+
+8.20 Support for executable extensions
+======================================
+
+On some platforms, such as Windows, executables are expected to have an
+extension such as '.exe'.  On these platforms, some compilers (GCC among
+them) will automatically generate 'foo.exe' when asked to generate
+'foo'.
+
+   Automake provides mostly-transparent support for this.  Unfortunately
+_mostly_ doesn't yet mean _fully_.  Until the English dictionary is
+revised, you will have to assist Automake if your package must support
+those platforms.
+
+   One thing you must be aware of is that, internally, Automake rewrites
+something like this:
+
+     bin_PROGRAMS = liver
+
+   to this:
+
+     bin_PROGRAMS = liver$(EXEEXT)
+
+   The targets Automake generates are likewise given the '$(EXEEXT)'
+extension.
+
+   The variables 'TESTS' and 'XFAIL_TESTS' (*note Simple Tests::) are
+also rewritten if they contain filenames that have been declared as
+programs in the same 'Makefile'.  (This is mostly useful when some
+programs from 'check_PROGRAMS' are listed in 'TESTS'.)
+
+   However, Automake cannot apply this rewriting to 'configure'
+substitutions.  This means that if you are conditionally building a
+program using such a substitution, then your 'configure.ac' must take
+care to add '$(EXEEXT)' when constructing the output variable.
+
+   Sometimes maintainers like to write an explicit link rule for their
+program.  Without executable extension support, this is easy--you simply
+write a rule whose target is the name of the program.  However, when
+executable extension support is enabled, you must instead add the
+'$(EXEEXT)' suffix.
+
+   This might be a nuisance for maintainers who know their package will
+never run on a platform that has executable extensions.  For those
+maintainers, the 'no-exeext' option (*note Options::) will disable this
+feature.  This works in a fairly ugly way; if 'no-exeext' is seen, then
+the presence of a rule for a target named 'foo' in 'Makefile.am' will
+override an 'automake'-generated rule for 'foo$(EXEEXT)'.  Without the
+'no-exeext' option, this use will give a diagnostic.

+
+9.1 Executable Scripts
+======================
+
+It is possible to define and install programs that are scripts.  Such
+programs are listed using the 'SCRIPTS' primary name.  When the script
+is distributed in its final, installable form, the 'Makefile' usually
+looks as follows:
+
+     # Install my_script in $(bindir) and distribute it.
+     dist_bin_SCRIPTS = my_script
+
+   Scripts are not distributed by default; as we have just seen, those
+that should be distributed can be specified using a 'dist_' prefix as
+with other primaries.
+
+   Scripts can be installed in 'bindir', 'sbindir', 'libexecdir',
+'pkglibexecdir', or 'pkgdatadir'.
+
+   Scripts that need not be installed can be listed in 'noinst_SCRIPTS',
+and among them, those which are needed only by 'make check' should go in
+'check_SCRIPTS'.
+
+   When a script needs to be built, the 'Makefile.am' should include the
+appropriate rules.  For instance the 'automake' program itself is a Perl
+script that is generated from 'automake.in'.  Here is how this is
+handled:
+
+     bin_SCRIPTS = automake
+     CLEANFILES = $(bin_SCRIPTS)
+     EXTRA_DIST = automake.in
+
+     do_subst = sed -e 's,[@]datadir[@],$(datadir),g' \
+                 -e 's,[@]PERL[@],$(PERL),g' \
+                 -e 's,[@]PACKAGE[@],$(PACKAGE),g' \
+                 -e 's,[@]VERSION[@],$(VERSION),g' \
+                 ...
+
+     automake: automake.in Makefile
+             $(do_subst) < $(srcdir)/automake.in > automake
+             chmod +x automake
+
+   Such scripts for which a build rule has been supplied need to be
+deleted explicitly using 'CLEANFILES' (*note Clean::), and their sources
+have to be distributed, usually with 'EXTRA_DIST' (*note Basics of
+Distribution::).
+
+   Another common way to build scripts is to process them from
+'configure' with 'AC_CONFIG_FILES'.  In this situation Automake knows
+which files should be cleaned and distributed, and what the rebuild
+rules should look like.
+
+   For instance if 'configure.ac' contains
+
+     AC_CONFIG_FILES([src/my_script], [chmod +x src/my_script])
+
+to build 'src/my_script' from 'src/my_script.in', then a
+'src/Makefile.am' to install this script in '$(bindir)' can be as simple
+as
+
+     bin_SCRIPTS = my_script
+     CLEANFILES = $(bin_SCRIPTS)
+
+There is no need for 'EXTRA_DIST' or any build rule: Automake infers
+them from 'AC_CONFIG_FILES' (*note Requirements::).  'CLEANFILES' is
+still useful, because by default Automake will clean targets of
+'AC_CONFIG_FILES' in 'distclean', not 'clean'.
+
+   Although this looks simpler, building scripts this way has one
+drawback: directory variables such as '$(datadir)' are not fully
+expanded and may refer to other directory variables.

+
+9.2 Header files
+================
+
+Header files that must be installed are specified by the 'HEADERS'
+family of variables.  Headers can be installed in 'includedir',
+'oldincludedir', 'pkgincludedir' or any other directory you may have
+defined (*note Uniform::).  For instance,
+
+     include_HEADERS = foo.h bar/bar.h
+
+will install the two files as '$(includedir)/foo.h' and
+'$(includedir)/bar.h'.
+
+   The 'nobase_' prefix is also supported,
+
+     nobase_include_HEADERS = foo.h bar/bar.h
+
+will install the two files as '$(includedir)/foo.h' and
+'$(includedir)/bar/bar.h' (*note Alternative::).
+
+   Usually, only header files that accompany installed libraries need to
+be installed.  Headers used by programs or convenience libraries are not
+installed.  The 'noinst_HEADERS' variable can be used for such headers.
+However when the header actually belongs to a single convenience library
+or program, we recommend listing it in the program's or library's
+'_SOURCES' variable (*note Program Sources::) instead of in
+'noinst_HEADERS'.  This is clearer for the 'Makefile.am' reader.
+'noinst_HEADERS' would be the right variable to use in a directory
+containing only headers and no associated library or program.
+
+   All header files must be listed somewhere; in a '_SOURCES' variable
+or in a '_HEADERS' variable.  Missing ones will not appear in the
+distribution.
+
+   For header files that are built and must not be distributed, use the
+'nodist_' prefix as in 'nodist_include_HEADERS' or
+'nodist_prog_SOURCES'.  If these generated headers are needed during the
+build, you must also ensure they exist before they are used (*note
+Sources::).
+

+
+9.3 Architecture-independent data files
+=======================================
+
+Automake supports the installation of miscellaneous data files using the
+'DATA' family of variables.
+
+   Such data can be installed in the directories 'datadir',
+'sysconfdir', 'sharedstatedir', 'localstatedir', or 'pkgdatadir'.
+
+   By default, data files are _not_ included in a distribution.  Of
+course, you can use the 'dist_' prefix to change this on a per-variable
+basis.
+
+   Here is how Automake declares its auxiliary data files:
+
+     dist_pkgdata_DATA = clean-kr.am clean.am ...
+
+
+File: automake.info,  Node: Sources,  Prev: Data,  Up: Other Objects
+
+9.4 Built Sources
+=================
+
+Because Automake's automatic dependency tracking works as a side-effect
+of compilation (*note Dependencies::) there is a bootstrap issue: a
+target should not be compiled before its dependencies are made, but
+these dependencies are unknown until the target is first compiled.
+
+   Ordinarily this is not a problem, because dependencies are
+distributed sources: they preexist and do not need to be built.  Suppose
+that 'foo.c' includes 'foo.h'.  When it first compiles 'foo.o', 'make'
+only knows that 'foo.o' depends on 'foo.c'.  As a side-effect of this
+compilation 'depcomp' records the 'foo.h' dependency so that following
+invocations of 'make' will honor it.  In these conditions, it's clear
+there is no problem: either 'foo.o' doesn't exist and has to be built
+(regardless of the dependencies), or accurate dependencies exist and
+they can be used to decide whether 'foo.o' should be rebuilt.
+
+   It's a different story if 'foo.h' doesn't exist by the first 'make'
+run.  For instance, there might be a rule to build 'foo.h'.  This time
+'file.o''s build will fail because the compiler can't find 'foo.h'.
+'make' failed to trigger the rule to build 'foo.h' first by lack of
+dependency information.
+
+   The 'BUILT_SOURCES' variable is a workaround for this problem.  A
+source file listed in 'BUILT_SOURCES' is made on 'make all' or 'make
+check' (or even 'make install') before other targets are processed.
+However, such a source file is not _compiled_ unless explicitly
+requested by mentioning it in some other '_SOURCES' variable.
+
+   So, to conclude our introductory example, we could use 'BUILT_SOURCES
+= foo.h' to ensure 'foo.h' gets built before any other target (including
+'foo.o') during 'make all' or 'make check'.
+
+   'BUILT_SOURCES' is actually a bit of a misnomer, as any file which
+must be created early in the build process can be listed in this
+variable.  Moreover, all built sources do not necessarily have to be
+listed in 'BUILT_SOURCES'.  For instance, a generated '.c' file doesn't
+need to appear in 'BUILT_SOURCES' (unless it is included by another
+source), because it's a known dependency of the associated object.
+
+   It might be important to emphasize that 'BUILT_SOURCES' is honored
+only by 'make all', 'make check' and 'make install'.  This means you
+cannot build a specific target (e.g., 'make foo') in a clean tree if it
+depends on a built source.  However it will succeed if you have run
+'make all' earlier, because accurate dependencies are already available.
+
+   The next section illustrates and discusses the handling of built
+sources on a toy example.
+
+* Menu:
+
+* Built Sources Example::       Several ways to handle built sources.
+
+
+File: automake.info,  Node: Built Sources Example,  Up: Sources
+
+9.4.1 Built Sources Example
+---------------------------
+
+Suppose that 'foo.c' includes 'bindir.h', which is
+installation-dependent and not distributed: it needs to be built.  Here
+'bindir.h' defines the preprocessor macro 'bindir' to the value of the
+'make' variable 'bindir' (inherited from 'configure').
+
+   We suggest several implementations below.  It's not meant to be an
+exhaustive listing of all ways to handle built sources, but it will give
+you a few ideas if you encounter this issue.
+
+First Try
+.........
+
+This first implementation will illustrate the bootstrap issue mentioned
+in the previous section (*note Sources::).
+
+   Here is a tentative 'Makefile.am'.
+
+     # This won't work.
+     bin_PROGRAMS = foo
+     foo_SOURCES = foo.c
+     nodist_foo_SOURCES = bindir.h
+     CLEANFILES = bindir.h
+     bindir.h: Makefile
+             echo '#define bindir "$(bindir)"' >$@
+
+   This setup doesn't work, because Automake doesn't know that 'foo.c'
+includes 'bindir.h'.  Remember, automatic dependency tracking works as a
+side-effect of compilation, so the dependencies of 'foo.o' will be known
+only after 'foo.o' has been compiled (*note Dependencies::).  The
+symptom is as follows.
+
+     % make
+     source='foo.c' object='foo.o' libtool=no \
+     depfile='.deps/foo.Po' tmpdepfile='.deps/foo.TPo' \
+     depmode=gcc /bin/sh ./depcomp \
+     gcc -I. -I. -g -O2 -c `test -f 'foo.c' || echo './'`foo.c
+     foo.c:2: bindir.h: No such file or directory
+     make: *** [foo.o] Error 1
+
+   In this example 'bindir.h' is not distributed nor installed, and it
+is not even being built on-time.  One may wonder if the
+'nodist_foo_SOURCES = bindir.h' line has any use at all.  This line
+simply states that 'bindir.h' is a source of 'foo', so for instance, it
+should be inspected while generating tags (*note Tags::).  In other
+words, it does not help our present problem, and the build would fail
+identically without it.
+
+Using 'BUILT_SOURCES'
+.....................
+
+A solution is to require 'bindir.h' to be built before anything else.
+This is what 'BUILT_SOURCES' is meant for (*note Sources::).
+
+     bin_PROGRAMS = foo
+     foo_SOURCES = foo.c
+     nodist_foo_SOURCES = bindir.h
+     BUILT_SOURCES = bindir.h
+     CLEANFILES = bindir.h
+     bindir.h: Makefile
+             echo '#define bindir "$(bindir)"' >$@
+
+   See how 'bindir.h' gets built first:
+
+     % make
+     echo '#define bindir "/usr/local/bin"' >bindir.h
+     make  all-am
+     make[1]: Entering directory `/home/adl/tmp'
+     source='foo.c' object='foo.o' libtool=no \
+     depfile='.deps/foo.Po' tmpdepfile='.deps/foo.TPo' \
+     depmode=gcc /bin/sh ./depcomp \
+     gcc -I. -I. -g -O2 -c `test -f 'foo.c' || echo './'`foo.c
+     gcc  -g -O2   -o foo  foo.o
+     make[1]: Leaving directory `/home/adl/tmp'
+
+   However, as said earlier, 'BUILT_SOURCES' applies only to the 'all',
+'check', and 'install' targets.  It still fails if you try to run 'make
+foo' explicitly:
+
+     % make clean
+     test -z "bindir.h" || rm -f bindir.h
+     test -z "foo" || rm -f foo
+     rm -f *.o
+     % : > .deps/foo.Po # Suppress previously recorded dependencies
+     % make foo
+     source='foo.c' object='foo.o' libtool=no \
+     depfile='.deps/foo.Po' tmpdepfile='.deps/foo.TPo' \
+     depmode=gcc /bin/sh ./depcomp \
+     gcc -I. -I. -g -O2 -c `test -f 'foo.c' || echo './'`foo.c
+     foo.c:2: bindir.h: No such file or directory
+     make: *** [foo.o] Error 1
+
+Recording Dependencies manually
+...............................
+
+Usually people are happy enough with 'BUILT_SOURCES' because they never
+build targets such as 'make foo' before 'make all', as in the previous
+example.  However if this matters to you, you can avoid 'BUILT_SOURCES'
+and record such dependencies explicitly in the 'Makefile.am'.
+
+     bin_PROGRAMS = foo
+     foo_SOURCES = foo.c
+     nodist_foo_SOURCES = bindir.h
+     foo.$(OBJEXT): bindir.h
+     CLEANFILES = bindir.h
+     bindir.h: Makefile
+             echo '#define bindir "$(bindir)"' >$@
+
+   You don't have to list _all_ the dependencies of 'foo.o' explicitly,
+only those that might need to be built.  If a dependency already exists,
+it will not hinder the first compilation and will be recorded by the
+normal dependency tracking code.  (Note that after this first
+compilation the dependency tracking code will also have recorded the
+dependency between 'foo.o' and 'bindir.h'; so our explicit dependency is
+really useful to the first build only.)
+
+   Adding explicit dependencies like this can be a bit dangerous if you
+are not careful enough.  This is due to the way Automake tries not to
+overwrite your rules (it assumes you know better than it).
+'foo.$(OBJEXT): bindir.h' supersedes any rule Automake may want to
+output to build 'foo.$(OBJEXT)'.  It happens to work in this case
+because Automake doesn't have to output any 'foo.$(OBJEXT):' target: it
+relies on a suffix rule instead (i.e., '.c.$(OBJEXT):').  Always check
+the generated 'Makefile.in' if you do this.
+
+Build 'bindir.h' from 'configure'
+.................................
+
+It's possible to define this preprocessor macro from 'configure', either
+in 'config.h' (*note Defining Directories: (autoconf)Defining
+Directories.), or by processing a 'bindir.h.in' file using
+'AC_CONFIG_FILES' (*note Configuration Actions: (autoconf)Configuration
+Actions.).
+
+   At this point it should be clear that building 'bindir.h' from
+'configure' works well for this example.  'bindir.h' will exist before
+you build any target, hence will not cause any dependency issue.
+
+   The Makefile can be shrunk as follows.  We do not even have to
+mention 'bindir.h'.
+
+     bin_PROGRAMS = foo
+     foo_SOURCES = foo.c
+
+   However, it's not always possible to build sources from 'configure',
+especially when these sources are generated by a tool that needs to be
+built first.
+
+Build 'bindir.c', not 'bindir.h'.
+.................................
+
+Another attractive idea is to define 'bindir' as a variable or function
+exported from 'bindir.o', and build 'bindir.c' instead of 'bindir.h'.
+
+     noinst_PROGRAMS = foo
+     foo_SOURCES = foo.c bindir.h
+     nodist_foo_SOURCES = bindir.c
+     CLEANFILES = bindir.c
+     bindir.c: Makefile
+             echo 'const char bindir[] = "$(bindir)";' >$@
+
+   'bindir.h' contains just the variable's declaration and doesn't need
+to be built, so it won't cause any trouble.  'bindir.o' is always
+dependent on 'bindir.c', so 'bindir.c' will get built first.
+
+Which is best?
+..............
+
+There is no panacea, of course.  Each solution has its merits and
+drawbacks.
+
+   You cannot use 'BUILT_SOURCES' if the ability to run 'make foo' on a
+clean tree is important to you.
+
+   You won't add explicit dependencies if you are leery of overriding an
+Automake rule by mistake.
+
+   Building files from './configure' is not always possible, neither is
+converting '.h' files into '.c' files.

+
+Since Automake is primarily intended to generate 'Makefile.in's for use

+
+File: automake.info,  Node: Emacs Lisp,  Next: gettext,  Up: Other GNU Tools
+
+10.1 Emacs Lisp
+===============
+
+Automake provides some support for Emacs Lisp.  The 'LISP' primary is
+used to hold a list of '.el' files.  Possible prefixes for this primary
+are 'lisp_' and 'noinst_'.  Note that if 'lisp_LISP' is defined, then
+'configure.ac' must run 'AM_PATH_LISPDIR' (*note Macros::).
+
+   Lisp sources are not distributed by default.  You can prefix the
+'LISP' primary with 'dist_', as in 'dist_lisp_LISP' or
+'dist_noinst_LISP', to indicate that these files should be distributed.
+
+   Automake will byte-compile all Emacs Lisp source files using the
+Emacs found by 'AM_PATH_LISPDIR', if any was found.  When performing
+such byte-compilation, the flags specified in the (developer-reserved)
+'AM_ELCFLAGS' and (user-reserved) 'ELCFLAGS' make variables will be
+passed to the Emacs invocation.
+
+   Byte-compiled Emacs Lisp files are not portable among all versions of
+Emacs, so it makes sense to turn this off if you expect sites to have
+more than one version of Emacs installed.  Furthermore, many packages
+don't actually benefit from byte-compilation.  Still, we recommend that
+you byte-compile your Emacs Lisp sources.  It is probably better for
+sites with strange setups to cope for themselves than to make the
+installation less nice for everybody else.
+
+   There are two ways to avoid byte-compiling.  Historically, we have
+recommended the following construct.
+
+     lisp_LISP = file1.el file2.el
+     ELCFILES =
+
+'ELCFILES' is an internal Automake variable that normally lists all
+'.elc' files that must be byte-compiled.  Automake defines 'ELCFILES'
+automatically from 'lisp_LISP'.  Emptying this variable explicitly
+prevents byte-compilation.
+
+   Since Automake 1.8, we now recommend using 'lisp_DATA' instead:
+
+     lisp_DATA = file1.el file2.el
+
+   Note that these two constructs are not equivalent.  '_LISP' will not
+install a file if Emacs is not installed, while '_DATA' will always
+install its files.

+
+10.2 Gettext
+============
+
+If 'AM_GNU_GETTEXT' is seen in 'configure.ac', then Automake turns on
+support for GNU gettext, a message catalog system for
+internationalization (*note Introduction: (gettext)Top.).
+
+   The 'gettext' support in Automake requires the addition of one or two
+subdirectories to the package: 'po' and possibly also 'intl'.  The
+latter is needed if 'AM_GNU_GETTEXT' is not invoked with the 'external'
+argument, or if 'AM_GNU_GETTEXT_INTL_SUBDIR' is used.  Automake ensures
+that these directories exist and are mentioned in 'SUBDIRS'.
+
+
+File: automake.info,  Node: Libtool,  Next: Java,  Prev: gettext,  Up: Other GNU Tools
+
+10.3 Libtool
+============
+
+Automake provides support for GNU Libtool (*note Introduction:
+(libtool)Top.) with the 'LTLIBRARIES' primary.  *Note A Shared
+Library::.
+
+
+File: automake.info,  Node: Java,  Next: Python,  Prev: Libtool,  Up: Other GNU Tools
+
+10.4 Java bytecode compilation (deprecated)
+===========================================
+
+Automake provides some minimal support for Java bytecode compilation
+with the 'JAVA' primary (in addition to the support for compiling Java
+to native machine code; *note Java Support with gcj::).  Note however
+that _the interface and most features described here are deprecated_.
+Future Automake releases will strive to provide a better and cleaner
+interface, which however _won't be backward-compatible_; the present
+interface will probably be removed altogether some time after the
+introduction of the new interface (if that ever materializes).
+
+   Any '.java' files listed in a '_JAVA' variable will be compiled with
+'JAVAC' at build time.  By default, '.java' files are not included in
+the distribution, you should use the 'dist_' prefix to distribute them.
+
+   Here is a typical setup for distributing '.java' files and installing
+the '.class' files resulting from their compilation.
+
+     javadir = $(datadir)/java
+     dist_java_JAVA = a.java b.java ...
+
+   Currently Automake enforces the restriction that only one '_JAVA'
+primary can be used in a given 'Makefile.am'.  The reason for this
+restriction is that, in general, it isn't possible to know which
+'.class' files were generated from which '.java' files, so it would be
+impossible to know which files to install where.  For instance, a
+'.java' file can define multiple classes; the resulting '.class' file
+names cannot be predicted without parsing the '.java' file.
+
+   There are a few variables that are used when compiling Java sources:
+
+'JAVAC'
+     The name of the Java compiler.  This defaults to 'javac'.
+
+'JAVACFLAGS'
+     The flags to pass to the compiler.  This is considered to be a user
+     variable (*note User Variables::).
+
+'AM_JAVACFLAGS'
+     More flags to pass to the Java compiler.  This, and not
+     'JAVACFLAGS', should be used when it is necessary to put Java
+     compiler flags into 'Makefile.am'.
+
+'JAVAROOT'
+     The value of this variable is passed to the '-d' option to 'javac'.
+     It defaults to '$(top_builddir)'.
+
+'CLASSPATH_ENV'
+     This variable is a shell expression that is used to set the
+     'CLASSPATH' environment variable on the 'javac' command line.  (In
+     the future we will probably handle class path setting differently.)
+
+
+File: automake.info,  Node: Python,  Prev: Java,  Up: Other GNU Tools
+
+10.5 Python
+===========
+
+Automake provides support for Python compilation with the 'PYTHON'
+primary.  A typical setup is to call 'AM_PATH_PYTHON' in 'configure.ac'
+and use a line like the following in 'Makefile.am':
+
+     python_PYTHON = tree.py leave.py
+
+   Any files listed in a '_PYTHON' variable will be byte-compiled with
+'py-compile' at install time.  'py-compile' actually creates both
+standard ('.pyc') and optimized ('.pyo') byte-compiled versions of the
+source files.  Note that because byte-compilation occurs at install
+time, any files listed in 'noinst_PYTHON' will not be compiled.  Python
+source files are included in the distribution by default, prepend
+'nodist_' (as in 'nodist_python_PYTHON') to omit them.
+
+   Automake ships with an Autoconf macro called 'AM_PATH_PYTHON' that
+will determine some Python-related directory variables (see below).  If
+you have called 'AM_PATH_PYTHON' from 'configure.ac', then you may use
+the variables 'python_PYTHON' or 'pkgpython_PYTHON' to list Python
+source files in your 'Makefile.am', depending on where you want your
+files installed (see the definitions of 'pythondir' and 'pkgpythondir'
+below).
+
+ -- Macro: AM_PATH_PYTHON ([VERSION], [ACTION-IF-FOUND],
+     [ACTION-IF-NOT-FOUND])
+
+     Search for a Python interpreter on the system.  This macro takes
+     three optional arguments.  The first argument, if present, is the
+     minimum version of Python required for this package:
+     'AM_PATH_PYTHON' will skip any Python interpreter that is older
+     than VERSION.  If an interpreter is found and satisfies VERSION,
+     then ACTION-IF-FOUND is run.  Otherwise, ACTION-IF-NOT-FOUND is
+     run.
+
+     If ACTION-IF-NOT-FOUND is not specified, as in the following
+     example, the default is to abort 'configure'.
+
+          AM_PATH_PYTHON([2.2])
+
+     This is fine when Python is an absolute requirement for the
+     package.  If Python >= 2.5 was only _optional_ to the package,
+     'AM_PATH_PYTHON' could be called as follows.
+
+          AM_PATH_PYTHON([2.5],, [:])
+
+     If the 'PYTHON' variable is set when 'AM_PATH_PYTHON' is called,
+     then that will be the only Python interpreter that is tried.
+
+     'AM_PATH_PYTHON' creates the following output variables based on
+     the Python installation found during configuration.
+
+'PYTHON'
+     The name of the Python executable, or ':' if no suitable
+     interpreter could be found.
+
+     Assuming ACTION-IF-NOT-FOUND is used (otherwise './configure' will
+     abort if Python is absent), the value of 'PYTHON' can be used to
+     setup a conditional in order to disable the relevant part of a
+     build as follows.
+
+          AM_PATH_PYTHON(,, [:])
+          AM_CONDITIONAL([HAVE_PYTHON], [test "$PYTHON" != :])
+
+'PYTHON_VERSION'
+     The Python version number, in the form MAJOR.MINOR (e.g., '2.5').
+     This is currently the value of 'sys.version[:3]'.
+
+'PYTHON_PREFIX'
+     The string '${prefix}'.  This term may be used in future work that
+     needs the contents of Python's 'sys.prefix', but general consensus
+     is to always use the value from 'configure'.
+
+'PYTHON_EXEC_PREFIX'
+     The string '${exec_prefix}'.  This term may be used in future work
+     that needs the contents of Python's 'sys.exec_prefix', but general
+     consensus is to always use the value from 'configure'.
+
+'PYTHON_PLATFORM'
+     The canonical name used by Python to describe the operating system,
+     as given by 'sys.platform'.  This value is sometimes needed when
+     building Python extensions.
+
+'pythondir'
+     The directory name for the 'site-packages' subdirectory of the
+     standard Python install tree.
+
+'pkgpythondir'
+     This is the directory under 'pythondir' that is named after the
+     package.  That is, it is '$(pythondir)/$(PACKAGE)'.  It is provided
+     as a convenience.
+
+'pyexecdir'
+     This is the directory where Python extension modules (shared
+     libraries) should be installed.  An extension module written in C
+     could be declared as follows to Automake:
+
+          pyexec_LTLIBRARIES = quaternion.la
+          quaternion_la_SOURCES = quaternion.c support.c support.h
+          quaternion_la_LDFLAGS = -avoid-version -module
+
+'pkgpyexecdir'
+     This is a convenience variable that is defined as
+     '$(pyexecdir)/$(PACKAGE)'.
+
+   All of these directory variables have values that start with either
+'${prefix}' or '${exec_prefix}' unexpanded.  This works fine in
+'Makefiles', but it makes these variables hard to use in 'configure'.
+This is mandated by the GNU coding standards, so that the user can run
+'make prefix=/foo install'.  The Autoconf manual has a section with more
+details on this topic (*note Installation Directory Variables:
+(autoconf)Installation Directory Variables.).  See also *note Hard-Coded
+Install Paths::.

+*************************
+
+Currently Automake provides support for Texinfo and man pages.
+
+* Menu:
+
+* Texinfo::                     Texinfo
+* Man Pages::                   Man pages
+
+
+File: automake.info,  Node: Texinfo,  Next: Man Pages,  Up: Documentation
+
+11.1 Texinfo
+============
+
+If the current directory contains Texinfo source, you must declare it
+with the 'TEXINFOS' primary.  Generally Texinfo files are converted into
+info, and thus the 'info_TEXINFOS' variable is most commonly used here.
+Any Texinfo source file should have the '.texi' extension.  Automake
+also accepts '.txi' or '.texinfo' extensions, but their use is
+discouraged now, and will elicit runtime warnings.
+
+   Automake generates rules to build '.info', '.dvi', '.ps', '.pdf' and
+'.html' files from your Texinfo sources.  Following the GNU Coding
+Standards, only the '.info' files are built by 'make all' and installed
+by 'make install' (unless you use 'no-installinfo', see below).
+Furthermore, '.info' files are automatically distributed so that Texinfo
+is not a prerequisite for installing your package.
+
+   It is worth noting that, contrary to what happens with the other
+formats, the generated '.info' files are by default placed in 'srcdir'
+rather than in the 'builddir'.  This can be changed with the
+'info-in-builddir' option.
+
+   Other documentation formats can be built on request by 'make dvi',
+'make ps', 'make pdf' and 'make html', and they can be installed with
+'make install-dvi', 'make install-ps', 'make install-pdf' and 'make
+install-html' explicitly.  'make uninstall' will remove everything: the
+Texinfo documentation installed by default as well as all the above
+optional formats.
+
+   All of these targets can be extended using '-local' rules (*note
+Extending::).
+
+   If the '.texi' file '@include's 'version.texi', then that file will
+be automatically generated.  The file 'version.texi' defines four
+Texinfo flag you can reference using '@value{EDITION}',
+'@value{VERSION}', '@value{UPDATED}', and '@value{UPDATED-MONTH}'.
+
+'EDITION'
+'VERSION'
+     Both of these flags hold the version number of your program.  They
+     are kept separate for clarity.
+
+'UPDATED'
+     This holds the date the primary '.texi' file was last modified.
+
+'UPDATED-MONTH'
+     This holds the name of the month in which the primary '.texi' file
+     was last modified.
+
+   The 'version.texi' support requires the 'mdate-sh' script; this
+script is supplied with Automake and automatically included when
+'automake' is invoked with the '--add-missing' option.
+
+   If you have multiple Texinfo files, and you want to use the
+'version.texi' feature, then you have to have a separate version file
+for each Texinfo file.  Automake will treat any include in a Texinfo
+file that matches 'vers*.texi' just as an automatically generated
+version file.
+
+   Sometimes an info file actually depends on more than one '.texi'
+file.  For instance, in GNU Hello, 'hello.texi' includes the file
+'fdl.texi'.  You can tell Automake about these dependencies using the
+'TEXI_TEXINFOS' variable.  Here is how GNU Hello does it:
+
+     info_TEXINFOS = hello.texi
+     hello_TEXINFOS = fdl.texi
+
+   By default, Automake requires the file 'texinfo.tex' to appear in the
+same directory as the 'Makefile.am' file that lists the '.texi' files.
+If you used 'AC_CONFIG_AUX_DIR' in 'configure.ac' (*note Finding
+'configure' Input: (autoconf)Input.), then 'texinfo.tex' is looked for
+there.  In both cases, 'automake' then supplies 'texinfo.tex' if
+'--add-missing' is given, and takes care of its distribution.  However,
+if you set the 'TEXINFO_TEX' variable (see below), it overrides the
+location of the file and turns off its installation into the source as
+well as its distribution.
+
+   The option 'no-texinfo.tex' can be used to eliminate the requirement
+for the file 'texinfo.tex'.  Use of the variable 'TEXINFO_TEX' is
+preferable, however, because that allows the 'dvi', 'ps', and 'pdf'
+targets to still work.
+
+   Automake generates an 'install-info' rule; some people apparently use
+this.  By default, info pages are installed by 'make install', so
+running 'make install-info' is pointless.  This can be prevented via the
+'no-installinfo' option.  In this case, '.info' files are not installed
+by default, and user must request this explicitly using 'make
+install-info'.
+
+   By default, 'make install-info' and 'make uninstall-info' will try to
+run the 'install-info' program (if available) to update (or
+create/remove) the '${infodir}/dir' index.  If this is undesired, it can
+be prevented by exporting the 'AM_UPDATE_INFO_DIR' variable to "'no'".
+
+   The following variables are used by the Texinfo build rules.
+
+'MAKEINFO'
+     The name of the program invoked to build '.info' files.  This
+     variable is defined by Automake.  If the 'makeinfo' program is
+     found on the system then it will be used by default; otherwise
+     'missing' will be used instead.
+
+'MAKEINFOHTML'
+     The command invoked to build '.html' files.  Automake defines this
+     to '$(MAKEINFO) --html'.
+
+'MAKEINFOFLAGS'
+     User flags passed to each invocation of '$(MAKEINFO)' and
+     '$(MAKEINFOHTML)'.  This user variable (*note User Variables::) is
+     not expected to be defined in any 'Makefile'; it can be used by
+     users to pass extra flags to suit their needs.
+
+'AM_MAKEINFOFLAGS'
+'AM_MAKEINFOHTMLFLAGS'
+     Maintainer flags passed to each 'makeinfo' invocation.  Unlike
+     'MAKEINFOFLAGS', these variables are meant to be defined by
+     maintainers in 'Makefile.am'.  '$(AM_MAKEINFOFLAGS)' is passed to
+     'makeinfo' when building '.info' files; and
+     '$(AM_MAKEINFOHTMLFLAGS)' is used when building '.html' files.
+
+     For instance, the following setting can be used to obtain one
+     single '.html' file per manual, without node separators.
+          AM_MAKEINFOHTMLFLAGS = --no-headers --no-split
+
+     'AM_MAKEINFOHTMLFLAGS' defaults to '$(AM_MAKEINFOFLAGS)'.  This
+     means that defining 'AM_MAKEINFOFLAGS' without defining
+     'AM_MAKEINFOHTMLFLAGS' will impact builds of both '.info' and
+     '.html' files.
+
+'TEXI2DVI'
+     The name of the command that converts a '.texi' file into a '.dvi'
+     file.  This defaults to 'texi2dvi', a script that ships with the
+     Texinfo package.
+
+'TEXI2PDF'
+     The name of the command that translates a '.texi' file into a
+     '.pdf' file.  This defaults to '$(TEXI2DVI) --pdf --batch'.
+
+'DVIPS'
+     The name of the command that builds a '.ps' file out of a '.dvi'
+     file.  This defaults to 'dvips'.
+
+'TEXINFO_TEX'
+
+     If your package has Texinfo files in many directories, you can use
+     the variable 'TEXINFO_TEX' to tell Automake where to find the
+     canonical 'texinfo.tex' for your package.  The value of this
+     variable should be the relative path from the current 'Makefile.am'
+     to 'texinfo.tex':
+
+          TEXINFO_TEX = ../doc/texinfo.tex
+
+
+File: automake.info,  Node: Man Pages,  Prev: Texinfo,  Up: Documentation
+
+11.2 Man Pages
+==============
+
+A package can also include man pages (but see the GNU standards on this
+matter, *note (standards)Man Pages::.)  Man pages are declared using the
+'MANS' primary.  Generally the 'man_MANS' variable is used.  Man pages
+are automatically installed in the correct subdirectory of 'mandir',
+based on the file extension.
+
+   File extensions such as '.1c' are handled by looking for the valid
+part of the extension and using that to determine the correct
+subdirectory of 'mandir'.  Valid section names are the digits '0'
+through '9', and the letters 'l' and 'n'.
+
+   Sometimes developers prefer to name a man page something like
+'foo.man' in the source, and then rename it to have the correct suffix,
+for example 'foo.1', when installing the file.  Automake also supports
+this mode.  For a valid section named SECTION, there is a corresponding
+directory named 'manSECTIONdir', and a corresponding '_MANS' variable.
+Files listed in such a variable are installed in the indicated section.
+If the file already has a valid suffix, then it is installed as-is;
+otherwise the file suffix is changed to match the section.
+
+   For instance, consider this example:
+     man1_MANS = rename.man thesame.1 alsothesame.1c
+
+In this case, 'rename.man' will be renamed to 'rename.1' when installed,
+but the other files will keep their names.
+
+   By default, man pages are installed by 'make install'.  However,
+since the GNU project does not require man pages, many maintainers do
+not expend effort to keep the man pages up to date.  In these cases, the
+'no-installman' option will prevent the man pages from being installed
+by default.  The user can still explicitly install them via 'make
+install-man'.
+
+   For fast installation, with many files it is preferable to use
+'manSECTION_MANS' over 'man_MANS' as well as files that do not need to
+be renamed.
+
+   Man pages are not currently considered to be source, because it is
+not uncommon for man pages to be automatically generated.  Therefore
+they are not automatically included in the distribution.  However, this
+can be changed by use of the 'dist_' prefix.  For instance here is how
+to distribute and install the two man pages of GNU 'cpio' (which
+includes both Texinfo documentation and man pages):
+
+     dist_man_MANS = cpio.1 mt.1
+
+   The 'nobase_' prefix is meaningless for man pages and is disallowed.
+
+   Executables and manpages may be renamed upon installation (*note
+Renaming::).  For manpages this can be avoided by use of the 'notrans_'
+prefix.  For instance, suppose an executable 'foo' allowing to access a
+library function 'foo' from the command line.  The way to avoid renaming
+of the 'foo.3' manpage is:
+
+     man_MANS = foo.1
+     notrans_man_MANS = foo.3
+
+   'notrans_' must be specified first when used in conjunction with
+either 'dist_' or 'nodist_' (*note Fine-grained Distribution Control::).
+For instance:
+
+     notrans_dist_man3_MANS = bar.3

+12 What Gets Installed
+**********************
+
+Naturally, Automake handles the details of actually installing your
+program once it has been built.  All files named by the various
+primaries are automatically installed in the appropriate places when the
+user runs 'make install'.

+
+
+File: automake.info,  Node: Basics of Installation,  Next: The Two Parts of Install,  Up: Install
+
+12.1 Basics of Installation
+===========================
+
+A file named in a primary is installed by copying the built file into
+the appropriate directory.  The base name of the file is used when
+installing.
+
+     bin_PROGRAMS = hello subdir/goodbye
+
+   In this example, both 'hello' and 'goodbye' will be installed in
+'$(bindir)'.
+
+   Sometimes it is useful to avoid the basename step at install time.
+For instance, you might have a number of header files in subdirectories
+of the source tree that are laid out precisely how you want to install
+them.  In this situation you can use the 'nobase_' prefix to suppress
+the base name step.  For example:
+
+     nobase_include_HEADERS = stdio.h sys/types.h
+
+will install 'stdio.h' in '$(includedir)' and 'types.h' in
+'$(includedir)/sys'.
+
+   For most file types, Automake will install multiple files at once,
+while avoiding command line length issues (*note Length Limitations::).
+Since some 'install' programs will not install the same file twice in
+one invocation, you may need to ensure that file lists are unique within
+one variable such as 'nobase_include_HEADERS' above.
+
+   You should not rely on the order in which files listed in one
+variable are installed.  Likewise, to cater for parallel make, you
+should not rely on any particular file installation order even among
+different file types (library dependencies are an exception here).
+
+
+File: automake.info,  Node: The Two Parts of Install,  Next: Extending Installation,  Prev: Basics of Installation,  Up: Install
+
+12.2 The Two Parts of Install
+=============================
+
+Automake generates separate 'install-data' and 'install-exec' rules, in
+case the installer is installing on multiple machines that share
+directory structure--these targets allow the machine-independent parts
+to be installed only once.  'install-exec' installs platform-dependent
+files, and 'install-data' installs platform-independent files.  The
+'install' target depends on both of these targets.  While Automake tries
+to automatically segregate objects into the correct category, the
+'Makefile.am' author is, in the end, responsible for making sure this is
+done correctly.
+
+   Variables using the standard directory prefixes 'data', 'info',
+'man', 'include', 'oldinclude', 'pkgdata', or 'pkginclude' are installed
+by 'install-data'.
+
+   Variables using the standard directory prefixes 'bin', 'sbin',
+'libexec', 'sysconf', 'localstate', 'lib', or 'pkglib' are installed by
+'install-exec'.
+
+   For instance, 'data_DATA' files are installed by 'install-data',
+while 'bin_PROGRAMS' files are installed by 'install-exec'.
+
+   Any variable using a user-defined directory prefix with 'exec' in the
+name (e.g., 'myexecbin_PROGRAMS') is installed by 'install-exec'.  All
+other user-defined prefixes are installed by 'install-data'.
+
+
+File: automake.info,  Node: Extending Installation,  Next: Staged Installs,  Prev: The Two Parts of Install,  Up: Install
+
+12.3 Extending Installation
+===========================
+
+It is possible to extend this mechanism by defining an
+'install-exec-local' or 'install-data-local' rule.  If these rules
+exist, they will be run at 'make install' time.  These rules can do
+almost anything; care is required.
+
+   Automake also supports two install hooks, 'install-exec-hook' and
+'install-data-hook'.  These hooks are run after all other install rules
+of the appropriate type, exec or data, have completed.  So, for
+instance, it is possible to perform post-installation modifications
+using an install hook.  *Note Extending::, for some examples.
+
+
+File: automake.info,  Node: Staged Installs,  Next: Install Rules for the User,  Prev: Extending Installation,  Up: Install
+
+12.4 Staged Installs
+====================
+
+Automake generates support for the 'DESTDIR' variable in all install
+rules.  'DESTDIR' is used during the 'make install' step to relocate
+install objects into a staging area.  Each object and path is prefixed
+with the value of 'DESTDIR' before being copied into the install area.
+Here is an example of typical DESTDIR usage:
+
+     mkdir /tmp/staging &&
+     make DESTDIR=/tmp/staging install
+
+   The 'mkdir' command avoids a security problem if the attacker creates
+a symbolic link from '/tmp/staging' to a victim area; then 'make' places
+install objects in a directory tree built under '/tmp/staging'.  If
+'/gnu/bin/foo' and '/gnu/share/aclocal/foo.m4' are to be installed, the
+above command would install '/tmp/staging/gnu/bin/foo' and
+'/tmp/staging/gnu/share/aclocal/foo.m4'.
+
+   This feature is commonly used to build install images and packages
+(*note DESTDIR::).
+
+   Support for 'DESTDIR' is implemented by coding it directly into the
+install rules.  If your 'Makefile.am' uses a local install rule (e.g.,
+'install-exec-local') or an install hook, then you must write that code
+to respect 'DESTDIR'.
+
+   *Note (standards)Makefile Conventions::, for another usage example.
+
+
+File: automake.info,  Node: Install Rules for the User,  Prev: Staged Installs,  Up: Install
+
+12.5 Install Rules for the User
+===============================
+
+Automake also generates rules for targets 'uninstall', 'installdirs',
+and 'install-strip'.
+
+   Automake supports 'uninstall-local' and 'uninstall-hook'.  There is
+no notion of separate uninstalls for "exec" and "data", as these
+features would not provide additional functionality.
+
+   Note that 'uninstall' is not meant as a replacement for a real
+packaging tool.
+
+
+File: automake.info,  Node: Clean,  Next: Dist,  Prev: Install,  Up: Top
+
+13 What Gets Cleaned
+********************
+
+The GNU Makefile Standards specify a number of different clean rules.
+*Note Standard Targets for Users: (standards)Standard Targets.
+
+   Generally the files that can be cleaned are determined automatically
+by Automake.  Of course, Automake also recognizes some variables that
+can be defined to specify additional files to clean.  These variables
+are 'MOSTLYCLEANFILES', 'CLEANFILES', 'DISTCLEANFILES', and
+'MAINTAINERCLEANFILES'.
+
+   When cleaning involves more than deleting some hard-coded list of
+files, it is also possible to supplement the cleaning rules with your
+own commands.  Simply define a rule for any of the 'mostlyclean-local',
+'clean-local', 'distclean-local', or 'maintainer-clean-local' targets
+(*note Extending::).  A common case is deleting a directory, for
+instance, a directory created by the test suite:
+
+     clean-local:
+             -rm -rf testSubDir
+
+   Since 'make' allows only one set of rules for a given target, a more
+extensible way of writing this is to use a separate target listed as a
+dependency:
+
+     clean-local: clean-local-check
+     .PHONY: clean-local-check
+     clean-local-check:
+             -rm -rf testSubDir
+
+   As the GNU Standards aren't always explicit as to which files should
+be removed by which rule, we've adopted a heuristic that we believe was
+first formulated by Franc,ois Pinard:
+
+   * If 'make' built it, and it is commonly something that one would
+     want to rebuild (for instance, a '.o' file), then 'mostlyclean'
+     should delete it.
+
+   * Otherwise, if 'make' built it, then 'clean' should delete it.
+
+   * If 'configure' built it, then 'distclean' should delete it.
+
+   * If the maintainer built it (for instance, a '.info' file), then
+     'maintainer-clean' should delete it.  However 'maintainer-clean'
+     should not delete anything that needs to exist in order to run
+     './configure && make'.
+
+   We recommend that you follow this same set of heuristics in your
+'Makefile.am'.

+
+* Basics of Distribution::      Files distributed by default
+* Fine-grained Distribution Control::  'dist_' and 'nodist_' prefixes
+* The dist Hook::               A target for last-minute distribution changes

+
+
+File: automake.info,  Node: Basics of Distribution,  Next: Fine-grained Distribution Control,  Up: Dist
+
+14.1 Basics of Distribution
+===========================
+
+The 'dist' rule in the generated 'Makefile.in' can be used to generate a
+gzipped 'tar' file and other flavors of archive for distribution.  The
+file is named based on the 'PACKAGE' and 'VERSION' variables defined by
+'AM_INIT_AUTOMAKE' (*note Macros::); more precisely the gzipped 'tar'
+file is named 'PACKAGE-VERSION.tar.gz'.  You can use the 'make' variable
+'GZIP_ENV' to control how gzip is run.  The default setting is '--best'.
+
+   For the most part, the files to distribute are automatically found by
+Automake: all source files are automatically included in a distribution,
+as are all 'Makefile.am' and 'Makefile.in' files.  Automake also has a
+built-in list of commonly used files that are automatically included if
+they are found in the current directory (either physically, or as the
+target of a 'Makefile.am' rule); this list is printed by 'automake
+--help'.  Note that some files in this list are actually distributed
+only if other certain conditions hold (for example, the 'config.h.top'
+and 'config.h.bot' files are automatically distributed only if, e.g.,
+'AC_CONFIG_HEADERS([config.h])' is used in 'configure.ac').  Also, files
+that are read by 'configure' (i.e. the source files corresponding to the
+files specified in various Autoconf macros such as 'AC_CONFIG_FILES' and
+siblings) are automatically distributed.  Files included in a
+'Makefile.am' (using 'include') or in 'configure.ac' (using
+'m4_include'), and helper scripts installed with 'automake
+--add-missing' are also distributed.
+
+   Still, sometimes there are files that must be distributed, but which
+are not covered in the automatic rules.  These files should be listed in
+the 'EXTRA_DIST' variable.  You can mention files from subdirectories in
+'EXTRA_DIST'.
+
+   You can also mention a directory in 'EXTRA_DIST'; in this case the
+entire directory will be recursively copied into the distribution.
+Please note that this will also copy _everything_ in the directory,
+including, e.g., Subversion's '.svn' private directories or CVS/RCS
+version control files; thus we recommend against using this feature
+as-is.  However, you can use the 'dist-hook' feature to ameliorate the
+problem; *note The dist Hook::.
+
+   If you define 'SUBDIRS', Automake will recursively include the
+subdirectories in the distribution.  If 'SUBDIRS' is defined
+conditionally (*note Conditionals::), Automake will normally include all
+directories that could possibly appear in 'SUBDIRS' in the distribution.
+If you need to specify the set of directories conditionally, you can set
+the variable 'DIST_SUBDIRS' to the exact list of subdirectories to
+include in the distribution (*note Conditional Subdirectories::).

+14.2 Fine-grained Distribution Control
+======================================
+
+Sometimes you need tighter control over what does _not_ go into the
+distribution; for instance, you might have source files that are
+generated and that you do not want to distribute.  In this case Automake
+gives fine-grained control using the 'dist' and 'nodist' prefixes.  Any
+primary or '_SOURCES' variable can be prefixed with 'dist_' to add the
+listed files to the distribution.  Similarly, 'nodist_' can be used to
+omit the files from the distribution.
+
+   As an example, here is how you would cause some data to be
+distributed while leaving some source code out of the distribution:
+
+     dist_data_DATA = distribute-this
+     bin_PROGRAMS = foo
+     nodist_foo_SOURCES = do-not-distribute.c
+

+
+14.3 The dist Hook
+==================
+
+Occasionally it is useful to be able to change the distribution before
+it is packaged up.  If the 'dist-hook' rule exists, it is run after the
+distribution directory is filled, but before the actual distribution
+archives are created.  One way to use this is for removing unnecessary
+files that get recursively included by specifying a directory in
+'EXTRA_DIST':
+
+     EXTRA_DIST = doc
+     dist-hook:
+             rm -rf `find $(distdir)/doc -type d -name .svn`
+
+Note that the 'dist-hook' recipe shouldn't assume that the regular files
+in the distribution directory are writable; this might not be the case
+if one is packaging from a read-only source tree, or when a 'make
+distcheck' is being done.  For similar reasons, the recipe shouldn't
+assume that the subdirectories put into the distribution directory as
+effect of having them listed in 'EXTRA_DIST' are writable.  So, if the
+'dist-hook' recipe wants to modify the content of an existing file (or
+'EXTRA_DIST' subdirectory) in the distribution directory, it should
+explicitly to make it writable first:
+
+     EXTRA_DIST = README doc
+     dist-hook:
+             chmod u+w $(distdir)/README $(distdir)/doc
+             echo "Distribution date: `date`" >> README
+             rm -f $(distdir)/doc/HACKING
+
+   Two variables that come handy when writing 'dist-hook' rules are
+'$(distdir)' and '$(top_distdir)'.
+
+   '$(distdir)' points to the directory where the 'dist' rule will copy
+files from the current directory before creating the tarball.  If you
+are at the top-level directory, then 'distdir = $(PACKAGE)-$(VERSION)'.
+When used from subdirectory named 'foo/', then 'distdir =
+../$(PACKAGE)-$(VERSION)/foo'.  '$(distdir)' can be a relative or
+absolute path, do not assume any form.
+
+   '$(top_distdir)' always points to the root directory of the
+distributed tree.  At the top-level it's equal to '$(distdir)'.  In the
+'foo/' subdirectory 'top_distdir = ../$(PACKAGE)-$(VERSION)'.
+'$(top_distdir)' too can be a relative or absolute path.
+
+   Note that when packages are nested using 'AC_CONFIG_SUBDIRS' (*note
+Subpackages::), then '$(distdir)' and '$(top_distdir)' are relative to
+the package where 'make dist' was run, not to any sub-packages involved.
+

+File: automake.info,  Node: Checking the Distribution,  Next: The Types of Distributions,  Prev: The dist Hook,  Up: Dist
+
+14.4 Checking the Distribution
+==============================
+
+Automake also generates a 'distcheck' rule that can be of help to ensure
+that a given distribution will actually work.  Simplifying a bit, we can
+say this rule first makes a distribution, and then, _operating from it_,
+takes the following steps:
+   * tries to do a 'VPATH' build (*note VPATH Builds::), with the
+     'srcdir' and all its content made _read-only_;
+   * runs the test suite (with 'make check') on this fresh build;
+   * installs the package in a temporary directory (with 'make
+     install'), and tries runs the test suite on the resulting
+     installation (with 'make installcheck');
+   * checks that the package can be correctly uninstalled (by 'make
+     uninstall') and cleaned (by 'make distclean');
+   * finally, makes another tarball to ensure the distribution is
+     self-contained.
+
+DISTCHECK_CONFIGURE_FLAGS
+-------------------------
+
+Building the package involves running './configure'.  If you need to
+supply additional flags to 'configure', define them in the
+'AM_DISTCHECK_CONFIGURE_FLAGS' variable in your top-level 'Makefile.am'.
+The user can still extend or override the flags provided there by
+defining the 'DISTCHECK_CONFIGURE_FLAGS' variable, on the command line
+when invoking 'make'.  It's worth nothing that 'make distcheck' needs
+complete control over the 'configure' options '--srcdir' and '--prefix',
+so those options cannot be overridden by 'AM_DISTCHECK_CONFIGURE_FLAGS'
+nor by 'DISTCHECK_CONFIGURE_FLAGS'.
+
+   Also note that developers are encouraged to strive to make their code
+buildable without requiring any special configure option; thus, in
+general, you shouldn't define 'AM_DISTCHECK_CONFIGURE_FLAGS'.  However,
+there might be few scenarios in which the use of this variable is
+justified.  GNU 'm4' offers an example.  GNU 'm4' configures by default
+with its experimental and seldom used "changeword" feature disabled; so
+in its case it is useful to have 'make distcheck' run configure with the
+'--with-changeword' option, to ensure that the code for changeword
+support still compiles correctly.  GNU 'm4' also employs the
+'AM_DISTCHECK_CONFIGURE_FLAGS' variable to stress-test the use of
+'--program-prefix=g', since at one point the 'm4' build system had a bug
+where 'make installcheck' was wrongly assuming it could blindly test
+"'m4'", rather than the just-installed "'gm4'".
+
+distcheck-hook
+--------------
+
+If the 'distcheck-hook' rule is defined in your top-level 'Makefile.am',
+then it will be invoked by 'distcheck' after the new distribution has
+been unpacked, but before the unpacked copy is configured and built.
+Your 'distcheck-hook' can do almost anything, though as always caution
+is advised.  Generally this hook is used to check for potential
+distribution errors not caught by the standard mechanism.  Note that
+'distcheck-hook' as well as 'AM_DISTCHECK_CONFIGURE_FLAGS' and
+'DISTCHECK_CONFIGURE_FLAGS' are not honored in a subpackage
+'Makefile.am', but the flags from 'AM_DISTCHECK_CONFIGURE_FLAGS' and
+'DISTCHECK_CONFIGURE_FLAGS' are passed down to the 'configure' script of
+the subpackage.
+
+distcleancheck
+--------------
+
+Speaking of potential distribution errors, 'distcheck' also ensures that
+the 'distclean' rule actually removes all built files.  This is done by
+running 'make distcleancheck' at the end of the 'VPATH' build.  By
+default, 'distcleancheck' will run 'distclean' and then make sure the
+build tree has been emptied by running '$(distcleancheck_listfiles)'.
+Usually this check will find generated files that you forgot to add to
+the 'DISTCLEANFILES' variable (*note Clean::).
+
+   The 'distcleancheck' behavior should be OK for most packages,
+otherwise you have the possibility to override the definition of either
+the 'distcleancheck' rule, or the '$(distcleancheck_listfiles)'
+variable.  For instance, to disable 'distcleancheck' completely, add the
+following rule to your top-level 'Makefile.am':
+
+     distcleancheck:
+             @:
+
+   If you want 'distcleancheck' to ignore built files that have not been
+cleaned because they are also part of the distribution, add the
+following definition instead:
+
+     distcleancheck_listfiles = \
+       find . -type f -exec sh -c 'test -f $(srcdir)/$$1 || echo $$1' \
+            sh '{}' ';'
+
+   The above definition is not the default because it's usually an error
+if your Makefiles cause some distributed files to be rebuilt when the
+user build the package.  (Think about the user missing the tool required
+to build the file; or if the required tool is built by your package,
+consider the cross-compilation case where it can't be run.)  There is an
+entry in the FAQ about this (*note Errors with distclean::), make sure
+you read it before playing with 'distcleancheck_listfiles'.
+
+distuninstallcheck
+------------------
+
+'distcheck' also checks that the 'uninstall' rule works properly, both
+for ordinary and 'DESTDIR' builds.  It does this by invoking 'make
+uninstall', and then it checks the install tree to see if any files are
+left over.  This check will make sure that you correctly coded your
+'uninstall'-related rules.
+
+   By default, the checking is done by the 'distuninstallcheck' rule,
+and the list of files in the install tree is generated by
+'$(distuninstallcheck_listfiles)' (this is a variable whose value is a
+shell command to run that prints the list of files to stdout).
+
+   Either of these can be overridden to modify the behavior of
+'distcheck'.  For instance, to disable this check completely, you would
+write:
+
+     distuninstallcheck:
+             @:

+1 Introduction
+**************
+
+In the past, if you were a source code package developer and wanted to
+take advantage of the power of shared libraries, you needed to write
+custom support code for each platform on which your package ran.  You
+also had to design a configuration interface so that the package
+installer could choose what sort of libraries were built.
+
+   GNU Libtool simplifies your job by encapsulating both the
+platform-specific dependencies, and the user interface, in a single
+script.  GNU Libtool is designed so that the complete functionality of
+each host type is available via a generic interface, but nasty quirks
+are hidden from the programmer.
+
+   GNU Libtool's consistent interface is reassuring... users don't need
+to read obscure documentation in order to have their favorite source
+package build shared libraries.  They just run your package `configure'
+script (or equivalent), and libtool does all the dirty work.
+
+   There are several examples throughout this document.  All assume the
+same environment: we want to build a library, `libhello', in a generic
+way.
+
+   `libhello' could be a shared library, a static library, or both...
+whatever is available on the host system, as long as libtool has been
+ported to it.
+
+   This chapter explains the original design philosophy of libtool.
+Feel free to skip to the next chapter, unless you are interested in
+history, or want to write code to extend libtool in a consistent way.

+File: libtool.info,  Node: Motivation,  Next: Issues,  Up: Introduction
+
+1.1 Motivation for writing libtool
+==================================
+
+Since early 1995, several different GNU developers have recognized the
+importance of having shared library support for their packages.  The
+primary motivation for such a change is to encourage modularity and
+reuse of code (both conceptually and physically) in GNU programs.
+
+   Such a demand means that the way libraries are built in GNU packages
+needs to be general, to allow for any library type the package installer
+might want.  The problem is compounded by the absence of a standard
+procedure for creating shared libraries on different platforms.
+
+   The following sections outline the major issues facing shared library
+support in GNU, and how shared library support could be standardized
+with libtool.
+
+   The following specifications were used in developing and evaluating
+this system:
+
+  1. The system must be as elegant as possible.
+
+  2. The system must be fully integrated with the GNU Autoconf and
+     Automake utilities, so that it will be easy for GNU maintainers to
+     use.  However, the system must not require these tools, so that it
+     can be used by non-GNU packages.
+
+  3. Portability to other (non-GNU) architectures and tools is
+     desirable.
+
+
+File: libtool.info,  Node: Issues,  Next: Other implementations,  Prev: Motivation,  Up: Introduction
+
+1.2 Implementation issues
+=========================
+
+The following issues need to be addressed in any reusable shared library
+system, specifically libtool:
+
+  1. The package installer should be able to control what sort of
+     libraries are built.
+
+  2. It can be tricky to run dynamically linked programs whose
+     libraries have not yet been installed.  `LD_LIBRARY_PATH' must be
+     set properly (if it is supported), or programs fail to run.
+
+  3. The system must operate consistently even on hosts that don't
+     support shared libraries.
+
+  4. The commands required to build shared libraries may differ wildly
+     from host to host.  These need to be determined at configure time
+     in a consistent way.
+
+  5. It is not always obvious with what prefix or suffix a shared
+     library should be installed.  This makes it difficult for
+     `Makefile' rules, since they generally assume that file names are
+     the same from host to host.
+
+  6. The system needs a simple library version number abstraction, so
+     that shared libraries can be upgraded in place.  The programmer
+     should be informed how to design the interfaces to the library to
+     maximize binary compatibility.
+
+  7. The install `Makefile' target should warn the package installer to
+     set the proper environment variables (`LD_LIBRARY_PATH' or
+     equivalent), or run `ldconfig'.

+
+1.3 Other implementations
+=========================
+
+Even before libtool was developed, many free software packages built and
+installed their own shared libraries.  At first, these packages were
+examined to avoid reinventing existing features.
+
+   Now it is clear that none of these packages have documented the
+details of shared library systems that libtool requires.  So, other
+packages have been more or less abandoned as influences.
+
+
+File: libtool.info,  Node: Postmortem,  Prev: Other implementations,  Up: Introduction
+
+1.4 A postmortem analysis of other implementations
+==================================================
+
+In all fairness, each of the implementations that were examined do the
+job that they were intended to do, for a number of different host
+systems.  However, none of these solutions seem to function well as a
+generalized, reusable component.
+
+   Most were too complex to use (much less modify) without understanding
+exactly what the implementation does, and they were generally not
+documented.
+
+   The main difficulty is that different vendors have different views of
+what libraries are, and none of the packages that were examined seemed
+to be confident enough to settle on a single paradigm that just _works_.
+
+   Ideally, libtool would be a standard that would be implemented as
+series of extensions and modifications to existing library systems to
+make them work consistently.  However, it is not an easy task to
+convince operating system developers to mend their evil ways, and
+people want to build shared libraries right now, even on buggy, broken,
+confused operating systems.
+
+   For this reason, libtool was designed as an independent shell script.
+It isolates the problems and inconsistencies in library building that
+plague `Makefile' writers by wrapping the compiler suite on different
+platforms with a consistent, powerful interface.
+
+   With luck, libtool will be useful to and used by the GNU community,
+and that the lessons that were learned in writing it will be taken up by
+designers of future library systems.

+
+2 The libtool paradigm
+**********************
+
+At first, libtool was designed to support an arbitrary number of library
+object types.  After libtool was ported to more platforms, a new
+paradigm gradually developed for describing the relationship between
+libraries and programs.
+
+   In summary, "libraries are programs with multiple entry points, and
+more formally defined interfaces."
+
+   Version 0.7 of libtool was a complete redesign and rewrite of
+libtool to reflect this new paradigm.  So far, it has proved to be
+successful: libtool is simpler and more useful than before.
+
+   The best way to introduce the libtool paradigm is to contrast it with
+the paradigm of existing library systems, with examples from each.  It
+is a new way of thinking, so it may take a little time to absorb, but
+when you understand it, the world becomes simpler.

+
+3 Using libtool
+***************
+
+It makes little sense to talk about using libtool in your own packages
+until you have seen how it makes your life simpler.  The examples in
+this chapter introduce the main features of libtool by comparing the
+standard library building procedure to libtool's operation on two
+different platforms:
+
+`a23'
+     An Ultrix 4.2 platform with only static libraries.
+
+`burger'
+     A NetBSD/i386 1.2 platform with shared libraries.
+
+   You can follow these examples on your own platform, using the
+preconfigured libtool script that was installed with libtool (*note
+Configuring::).
+
+   Source files for the following examples are taken from the `demo'
+subdirectory of the libtool distribution.  Assume that we are building a
+library, `libhello', out of the files `foo.c' and `hello.c'.
+
+   Note that the `foo.c' source file uses the `cos' math library
+function, which is usually found in the standalone math library, and not
+the C library (*note Trigonometric Functions: (libc)Trig Functions.).
+So, we need to add `-lm' to the end of the link line whenever we link
+`foo.lo' into an executable or a library (*note Inter-library
+dependencies::).
+
+   The same rule applies whenever you use functions that don't appear in
+the standard C library... you need to add the appropriate `-lNAME' flag
+to the end of the link line when you link against those objects.
+
+   After we have built that library, we want to create a program by
+linking `main.o' against `libhello'.

+
+
+File: libtool.info,  Node: Creating object files,  Next: Linking libraries,  Up: Using libtool
+
+3.1 Creating object files
+=========================
+
+To create an object file from a source file, the compiler is invoked
+with the `-c' flag (and any other desired flags):
+
+     burger$ gcc -g -O -c main.c
+     burger$
+
+   The above compiler command produces an object file, usually named
+`main.o', from the source file `main.c'.
+
+   For most library systems, creating object files that become part of a
+static library is as simple as creating object files that are linked to
+form an executable:
+
+     burger$ gcc -g -O -c foo.c
+     burger$ gcc -g -O -c hello.c
+     burger$
+
+   Shared libraries, however, may only be built from
+"position-independent code" (PIC).  So, special flags must be passed to
+the compiler to tell it to generate PIC rather than the standard
+position-dependent code.
+
+   Since this is a library implementation detail, libtool hides the
+complexity of PIC compiler flags and uses separate library object files
+(the PIC one lives in the `.libs' subdirectory and the static one lives
+in the current directory).  On systems without shared libraries, the
+PIC library object files are not created, whereas on systems where all
+code is PIC, such as AIX, the static ones are not created.
+
+   To create library object files for `foo.c' and `hello.c', simply
+invoke libtool with the standard compilation command as arguments
+(*note Compile mode::):
+
+     a23$ libtool --mode=compile gcc -g -O -c foo.c
+     gcc -g -O -c foo.c -o foo.o
+     a23$ libtool --mode=compile gcc -g -O -c hello.c
+     gcc -g -O -c hello.c -o hello.o
+     a23$
+
+   Note that libtool silently creates an additional control file on each
+`compile' invocation.  The `.lo' file is the libtool object, which
+Libtool uses to determine what object file may be built into a shared
+library.  On `a23', only static libraries are supported so the library
+objects look like this:
+
+     # foo.lo - a libtool object file
+     # Generated by ltmain.sh (GNU libtool) 2.4.2
+     #
+     # Please DO NOT delete this file!
+     # It is necessary for linking the library.
+
+     # Name of the PIC object.
+     pic_object=none
+
+     # Name of the non-PIC object.
+     non_pic_object='foo.o'
+
+   On shared library systems, libtool automatically generates an
+additional PIC object by inserting the appropriate PIC generation flags
+into the compilation command:
+
+     burger$ libtool --mode=compile gcc -g -O -c foo.c
+     mkdir .libs
+     gcc -g -O -c foo.c  -fPIC -DPIC -o .libs/foo.o
+     gcc -g -O -c foo.c -o foo.o >/dev/null 2>&1
+     burger$
+
+   Note that Libtool automatically created `.libs' directory upon its
+first execution, where PIC library object files will be stored.
+
+   Since `burger' supports shared libraries, and requires PIC objects
+to build them, Libtool has compiled a PIC object this time, and made a
+note of it in the libtool object:
+
+     # foo.lo - a libtool object file
+     # Generated by ltmain.sh (GNU libtool) 2.4.2
+     #
+     # Please DO NOT delete this file!
+     # It is necessary for linking the library.
+
+     # Name of the PIC object.
+     pic_object='.libs/foo.o'
+
+     # Name of the non-PIC object.
+     non_pic_object='foo.o'
+
+   Notice that the second run of GCC has its output discarded.  This is
+done so that compiler warnings aren't annoyingly duplicated.  If you
+need to see both sets of warnings (you might have conditional code
+inside `#ifdef PIC' for example), you can turn off suppression with the
+`-no-suppress' option to libtool's compile mode:
+
+     burger$ libtool --mode=compile gcc -no-suppress -g -O -c hello.c
+     gcc -g -O -c hello.c  -fPIC -DPIC -o .libs/hello.o
+     gcc -g -O -c hello.c -o hello.o
+     burger$
+

+File: libtool.info,  Node: Linking libraries,  Next: Linking executables,  Prev: Creating object files,  Up: Using libtool
+
+3.2 Linking libraries
+=====================
+
+Without libtool, the programmer would invoke the `ar' command to create
+a static library:
+
+     burger$ ar cru libhello.a hello.o foo.o
+     burger$
+
+   But of course, that would be too simple, so many systems require that
+you run the `ranlib' command on the resulting library (to give it
+better karma, or something):
+
+     burger$ ranlib libhello.a
+     burger$
+
+   It seems more natural to use the C compiler for this task, given
+libtool's "libraries are programs" approach.  So, on platforms without
+shared libraries, libtool simply acts as a wrapper for the system `ar'
+(and possibly `ranlib') commands.
+
+   Again, the libtool control file name (`.la' suffix) differs from the
+standard library name (`.a' suffix).  The arguments to libtool are the
+same ones you would use to produce an executable named `libhello.la'
+with your compiler (*note Link mode::):
+
+     a23$ libtool --mode=link gcc -g -O -o libhello.la foo.o hello.o
+     *** Warning: Linking the shared library libhello.la against the
+     *** non-libtool objects foo.o hello.o is not portable!
+     ar cru .libs/libhello.a
+     ranlib .libs/libhello.a
+     creating libhello.la
+     (cd .libs && rm -f libhello.la && ln -s ../libhello.la libhello.la)
+     a23$
+
+   Aha!  Libtool caught a common error... trying to build a library
+from standard objects instead of special `.lo' object files.  This
+doesn't matter so much for static libraries, but on shared library
+systems, it is of great importance.  (Note that you may replace
+`libhello.la' with `libhello.a' in which case libtool won't issue the
+warning any more.  But although this method works, this is not intended
+to be used because it makes you lose the benefits of using Libtool.)
+
+   So, let's try again, this time with the library object files.
+Remember also that we need to add `-lm' to the link command line because
+`foo.c' uses the `cos' math library function (*note Using libtool::).
+
+   Another complication in building shared libraries is that we need to
+specify the path to the directory in which they (eventually) will be
+installed (in this case, `/usr/local/lib')(1):
+
+     a23$ libtool --mode=link gcc -g -O -o libhello.la foo.lo hello.lo \
+                     -rpath /usr/local/lib -lm
+     ar cru .libs/libhello.a foo.o hello.o
+     ranlib .libs/libhello.a
+     creating libhello.la
+     (cd .libs && rm -f libhello.la && ln -s ../libhello.la libhello.la)
+     a23$
+
+   Now, let's try the same trick on the shared library platform:
+
+     burger$ libtool --mode=link gcc -g -O -o libhello.la foo.lo hello.lo \
+                     -rpath /usr/local/lib -lm
+     rm -fr  .libs/libhello.a .libs/libhello.la
+     ld -Bshareable -o .libs/libhello.so.0.0 .libs/foo.o .libs/hello.o -lm
+     ar cru .libs/libhello.a foo.o hello.o
+     ranlib .libs/libhello.a
+     creating libhello.la
+     (cd .libs && rm -f libhello.la && ln -s ../libhello.la libhello.la)
+     burger$
+
+   Now that's significantly cooler... Libtool just ran an obscure `ld'
+command to create a shared library, as well as the static library.
+
+   Note how libtool creates extra files in the `.libs' subdirectory,
+rather than the current directory.  This feature is to make it easier
+to clean up the build directory, and to help ensure that other programs
+fail horribly if you accidentally forget to use libtool when you should.
+
+   Again, you may want to have a look at the `.la' file in order to see
+what Libtool stores in it.  In particular, you will see that Libtool
+uses this file to remember the destination directory for the library
+(the argument to `-rpath') as well as the dependency on the math
+library (`-lm').
+
+   ---------- Footnotes ----------
+
+   (1) If you don't specify an `rpath', then libtool builds a libtool
+convenience archive, not a shared library (*note Static libraries::).

+
+3.3 Linking executables
+=======================
+
+If you choose at this point to "install" the library (put it in a
+permanent location) before linking executables against it, then you
+don't need to use libtool to do the linking.  Simply use the appropriate
+`-L' and `-l' flags to specify the library's location.
+
+   Some system linkers insist on encoding the full directory name of
+each shared library in the resulting executable.  Libtool has to work
+around this misfeature by special magic to ensure that only permanent
+directory names are put into installed executables.
+
+   The importance of this bug must not be overlooked: it won't cause
+programs to crash in obvious ways.  It creates a security hole, and
+possibly even worse, if you are modifying the library source code after
+you have installed the package, you will change the behaviour of the
+installed programs!
+
+   So, if you want to link programs against the library before you
+install it, you must use libtool to do the linking.
+
+   Here's the old way of linking against an uninstalled library:
+
+     burger$ gcc -g -O -o hell.old main.o libhello.a -lm
+     burger$
+
+   Libtool's way is almost the same(1) (*note Link mode::):
+
+     a23$ libtool --mode=link gcc -g -O -o hell main.o libhello.la
+     gcc -g -O -o hell main.o  ./.libs/libhello.a -lm
+     a23$
+
+   That looks too simple to be true.  All libtool did was transform
+`libhello.la' to `./.libs/libhello.a', but remember that `a23' has no
+shared libraries.  Notice that Libtool also remembered that
+`libhello.la' depends on `-lm', so even though we didn't specify `-lm'
+on the libtool command line(2) Libtool has added it to the `gcc' link
+line for us.
+
+   On `burger' Libtool links against the uninstalled shared library:
+
+     burger$ libtool --mode=link gcc -g -O -o hell main.o libhello.la
+     gcc -g -O -o .libs/hell main.o -L./.libs -R/usr/local/lib -lhello -lm
+     creating hell
+     burger$
+
+   Now assume `libhello.la' had already been installed, and you want to
+link a new program with it.  You could figure out where it lives by
+yourself, then run:
+
+     burger$ gcc -g -O -o test test.o -L/usr/local/lib -lhello -lm
+
+   However, unless `/usr/local/lib' is in the standard library search
+path, you won't be able to run `test'.  However, if you use libtool to
+link the already-installed libtool library, it will do The Right Thing
+(TM) for you:
+
+     burger$ libtool --mode=link gcc -g -O -o test test.o \
+                     /usr/local/lib/libhello.la
+     gcc -g -O -o .libs/test test.o -Wl,--rpath \
+             -Wl,/usr/local/lib /usr/local/lib/libhello.a -lm
+     creating test
+     burger$
+
+   Note that libtool added the necessary run-time path flag, as well as
+`-lm', the library libhello.la depended upon.  Nice, huh?
+
+   Notice that the executable, `hell', was actually created in the
+`.libs' subdirectory.  Then, a wrapper script (or, on certain
+platforms, a wrapper executable *note Wrapper executables::) was
+created in the current directory.
+
+   Since libtool created a wrapper script, you should use libtool to
+install it and debug it too.  However, since the program does not depend
+on any uninstalled libtool library, it is probably usable even without
+the wrapper script.
+
+   On NetBSD 1.2, libtool encodes the installation directory of
+`libhello', by using the `-R/usr/local/lib' compiler flag.  Then, the
+wrapper script guarantees that the executable finds the correct shared
+library (the one in `./.libs') until it is properly installed.
+
+   Let's compare the two different programs:
+
+     burger$ time ./hell.old
+     Welcome to GNU Hell!
+     ** This is not GNU Hello.  There is no built-in mail reader. **
+             0.21 real         0.02 user         0.08 sys
+     burger$ time ./hell
+     Welcome to GNU Hell!
+     ** This is not GNU Hello.  There is no built-in mail reader. **
+             0.63 real         0.09 user         0.59 sys
+     burger$
+
+   The wrapper script takes significantly longer to execute, but at
+least the results are correct, even though the shared library hasn't
+been installed yet.
+
+   So, what about all the space savings that shared libraries are
+supposed to yield?
+
+     burger$ ls -l hell.old libhello.a
+     -rwxr-xr-x  1 gord  gord  15481 Nov 14 12:11 hell.old
+     -rw-r--r--  1 gord  gord   4274 Nov 13 18:02 libhello.a
+     burger$ ls -l .libs/hell .libs/libhello.*
+     -rwxr-xr-x  1 gord  gord  11647 Nov 14 12:10 .libs/hell
+     -rw-r--r--  1 gord  gord   4274 Nov 13 18:44 .libs/libhello.a
+     -rwxr-xr-x  1 gord  gord  12205 Nov 13 18:44 .libs/libhello.so.0.0
+     burger$
+
+   Well, that sucks.  Maybe I should just scrap this project and take up
+basket weaving.
+
+   Actually, it just proves an important point: shared libraries incur
+overhead because of their (relative) complexity.  In this situation, the
+price of being dynamic is eight kilobytes, and the payoff is about four
+kilobytes.  So, having a shared `libhello' won't be an advantage until
+we link it against at least a few more programs.

+
+   (1) However, you should avoid using `-L' or `-l' flags to link

+to the `.la' file, such as `../intl/libintl.la'.  This is a design
+decision to eliminate any ambiguity when linking against uninstalled
+shared libraries.

+3.3.1 Wrapper executables for uninstalled programs
+--------------------------------------------------
+
+Some platforms, notably those hosted on Windows such as Cygwin and
+MinGW, use a wrapper executable rather than a wrapper script to ensure
+proper operation of uninstalled programs linked by libtool against
+uninstalled shared libraries. The wrapper executable thus performs the
+same function as the wrapper script used on other platforms, but allows
+to satisfy the `make' rules for the program, whose name ends in
+`$(EXEEXT)'. The actual program executable is created below .libs, and
+its name will end in `$(EXEEXT)' and may or may not contain an `lt-'
+prefix.  This wrapper executable sets various environment values so
+that the program executable may locate its (uninstalled) shared
+libraries, and then launches the program executable.
+
+   The wrapper executable provides a debug mode, enabled by passing the
+command-line option `--lt-debug' (see below). When executing in debug
+mode, diagnostic information will be printed to `stderr' before the
+program executable is launched.
+
+   Finally, the wrapper executable supports a number of command line
+options that may be useful when debugging the operation of the wrapper
+system. All of these options begin with `--lt-', and if present they
+and their arguments will be removed from the argument list passed on to
+the program executable.  Therefore, the program executable may not
+employ command line options that begin with `--lt-'. (In fact, the
+wrapper executable will detect any command line options that begin with
+`--lt-' and abort with an error message if the option is not
+recognized). If this presents a problem, please contact the Libtool
+team at the Libtool bug reporting address <bug-libtool@gnu.org>.
+
+   These command line options include:
+
+`--lt-dump-script'
+     Causes the wrapper to print a copy of the wrapper _script_ to
+     `stdout', and exit.
+
+`--lt-debug'
+     Causes the wrapper to print diagnostic information to `stdout',
+     before launching the program executable.
+
+
+   For consistency, both the wrapper _script_ and the wrapper
+_executable_ support these options.

+3.4 Debugging executables
+=========================
+
+If `hell' was a complicated program, you would certainly want to test
+and debug it before installing it on your system.  In the above
+section, you saw how the libtool wrapper script makes it possible to run
+the program directly, but unfortunately, this mechanism interferes with
+the debugger:
+
+     burger$ gdb hell
+     GDB is free software and you are welcome to distribute copies of it
+      under certain conditions; type "show copying" to see the conditions.
+     There is no warranty for GDB; type "show warranty" for details.

+
+     "hell": not in executable format: File format not recognized
+
+     (gdb) quit
+     burger$
+
+   Sad.  It doesn't work because GDB doesn't know where the executable
+lives.  So, let's try again, by invoking GDB directly on the executable:
+
+     burger$ gdb .libs/hell
+     GNU gdb 5.3 (i386-unknown-netbsd)
+     Copyright 2002 Free Software Foundation, Inc.
+     GDB is free software, covered by the GNU General Public License,

+     (gdb) break main
+     Breakpoint 1 at 0x8048547: file main.c, line 29.

+
+     Program exited with code 020.
+     (gdb) quit
+     burger$
+
+   Argh.  Now GDB complains because it cannot find the shared library
+that `hell' is linked against.  So, we must use libtool in order to
+properly set the library path and run the debugger.  Fortunately, we can
+forget all about the `.libs' directory, and just run it on the
+executable wrapper (*note Execute mode::):
+
+     burger$ libtool --mode=execute gdb hell

+
+3.5 Installing libraries
+========================
+
+Installing libraries on a non-libtool system is quite
+straightforward... just copy them into place:(1)
+
+     burger$ su
+     Password: ********
+     burger# cp libhello.a /usr/local/lib/libhello.a
+     burger#
+
+   Oops, don't forget the `ranlib' command:
+
+     burger# ranlib /usr/local/lib/libhello.a
+     burger#
+
+   Libtool installation is quite simple, as well.  Just use the
+`install' or `cp' command that you normally would (*note Install
+mode::):
+
+     a23# libtool --mode=install cp libhello.la /usr/local/lib/libhello.la
+     cp libhello.la /usr/local/lib/libhello.la
+     cp .libs/libhello.a /usr/local/lib/libhello.a
+     ranlib /usr/local/lib/libhello.a
+     a23#
+
+   Note that the libtool library `libhello.la' is also installed, to
+help libtool with uninstallation (*note Uninstall mode::) and linking
+(*note Linking executables::) and to help programs with dlopening
+(*note Dlopened modules::).
+
+   Here is the shared library example:
+
+     burger# libtool --mode=install install -c libhello.la \
+                     /usr/local/lib/libhello.la
+     install -c .libs/libhello.so.0.0 /usr/local/lib/libhello.so.0.0
+     install -c libhello.la /usr/local/lib/libhello.la
+     install -c .libs/libhello.a /usr/local/lib/libhello.a
+     ranlib /usr/local/lib/libhello.a
+     burger#
+
+   It is safe to specify the `-s' (strip symbols) flag if you use a
+BSD-compatible install program when installing libraries.  Libtool will
+either ignore the `-s' flag, or will run a program that will strip only
+debugging and compiler symbols from the library.
+
+   Once the libraries have been put in place, there may be some
+additional configuration that you need to do before using them.  First,
+you must make sure that where the library is installed actually agrees
+with the `-rpath' flag you used to build it.
+
+   Then, running `libtool -n finish LIBDIR' can give you further hints
+on what to do (*note Finish mode::):
+
+     burger# libtool -n finish /usr/local/lib
+     PATH="$PATH:/sbin" ldconfig -m /usr/local/lib
+     -----------------------------------------------------------------
+     Libraries have been installed in:
+        /usr/local/lib
+
+     To link against installed libraries in a given directory, LIBDIR,
+     you must use the `-LLIBDIR' flag during linking.
+
+      You will also need to do one of the following:
+        - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
+          during execution
+        - add LIBDIR to the `LD_RUN_PATH' environment variable
+          during linking
+        - use the `-RLIBDIR' linker flag
+
+     See any operating system documentation about shared libraries for
+     more information, such as the ld and ld.so manual pages.
+     -----------------------------------------------------------------
+     burger#
+
+   After you have completed these steps, you can go on to begin using
+the installed libraries.  You may also install any executables that
+depend on libraries you created.
+

+
+3.6 Installing executables
+==========================
+
+If you used libtool to link any executables against uninstalled libtool
+libraries (*note Linking executables::), you need to use libtool to
+install the executables after the libraries have been installed (*note
+Installing libraries::).
+
+   So, for our Ultrix example, we would run:
+
+     a23# libtool --mode=install -c hell /usr/local/bin/hell
+     install -c hell /usr/local/bin/hell
+     a23#
+
+   On shared library systems that require wrapper scripts, libtool just
+ignores the wrapper script and installs the correct binary:
+
+     burger# libtool --mode=install -c hell /usr/local/bin/hell
+     install -c .libs/hell /usr/local/bin/hell
+     burger#
+
+
+File: libtool.info,  Node: Static libraries,  Prev: Installing executables,  Up: Using libtool
+
+3.7 Linking static libraries
+============================
+
+Why return to `ar' and `ranlib' silliness when you've had a taste of
+libtool?  Well, sometimes it is desirable to create a static archive
+that can never be shared.  The most frequent case is when you have a
+set of object files that you use to build several different libraries.
+You can create a "convenience library" out of those objects, and link
+against that with the other libraries, instead of listing all the
+object files every time.
+
+   If you just want to link this convenience library into programs, then
+you could just ignore libtool entirely, and use the old `ar' and
+`ranlib' commands (or the corresponding GNU Automake `_LIBRARIES'
+rules).  You can even install a convenience library using GNU Libtool,
+though you probably don't want to and hence GNU Automake doesn't allow
+you to do so.
+
+     burger$ libtool --mode=install ./install-sh -c libhello.a \
+                     /local/lib/libhello.a
+     ./install-sh -c libhello.a /local/lib/libhello.a
+     ranlib /local/lib/libhello.a
+     burger$
+
+   Using libtool for static library installation protects your library
+from being accidentally stripped (if the installer used the `-s' flag),
+as well as automatically running the correct `ranlib' command.
+
+   But libtool libraries are more than just collections of object files:
+they can also carry library dependency information, which old archives
+do not.  If you want to create a libtool static convenience library, you
+can omit the `-rpath' flag and use `-static' to indicate that you're
+only interested in a static library.  When you link a program with such
+a library, libtool will actually link all object files and dependency
+libraries into the program.
+
+   If you omit both `-rpath' and `-static', libtool will create a
+convenience library that can be used to create other libtool libraries,
+even shared ones.  Just like in the static case, the library behaves as
+an alias to a set of object files and dependency libraries, but in this
+case the object files are suitable for inclusion in shared libraries.
+But be careful not to link a single convenience library, directly or
+indirectly, into a single program or library, otherwise you may get
+errors about symbol redefinitions.
+
+   The key is remembering that a convenience library contains PIC
+objects, and can be linked where a list of PIC objects makes sense;
+i.e. into a shared library.  A static convenience library contains
+non-PIC objects, so can be linked into an old static library, or a
+program.
+
+   When GNU Automake is used, you should use `noinst_LTLIBRARIES'
+instead of `lib_LTLIBRARIES' for convenience libraries, so that the
+`-rpath' option is not passed when they are linked.
+
+   As a rule of thumb, link a libtool convenience library into at most
+one libtool library, and never into a program, and link libtool static
+convenience libraries only into programs, and only if you need to carry
+library dependency information to the user of the static convenience
+library.
+
+   Another common situation where static linking is desirable is in
+creating a standalone binary.  Use libtool to do the linking and add the
+`-all-static' flag.

+4 Invoking `libtool'
+********************
+
+The `libtool' program has the following synopsis:
+
+     libtool [OPTION]... [MODE-ARG]...
+
+and accepts the following options:
+
+`--config'
+     Display libtool configuration variables and exit.
+
+`--debug'
+     Dump a trace of shell script execution to standard output.  This
+     produces a lot of output, so you may wish to pipe it to `less' (or
+     `more') or redirect to a file.
+
+`-n'
+`--dry-run'
+     Don't create, modify, or delete any files, just show what commands
+     would be executed by libtool.
+
+`--features'
+     Display basic configuration options.  This provides a way for
+     packages to determine whether shared or static libraries will be
+     built.
+
+`--finish'
+     Same as `--mode=finish'.
+
+`-h'
+     Display short help message.
+
+`--help'
+     Display a help message and exit.  If `--mode=MODE' is specified,
+     then detailed help for MODE is displayed.
+
+`--help-all'
+     Display help for the general options as well as detailed help for
+     each operation mode, and exit.
+
+`--mode=MODE'
+     Use MODE as the operation mode.  When using libtool from the
+     command line, you can give just MODE (or a unique abbreviation of
+     it) as the first argument as a shorthand for the full
+     `--mode=MODE'.  For example, the following are equivalent:
+
+          $ libtool --mode=execute --dry-run gdb prog.exe
+          $ libtool        execute --dry-run gdb prog.exe
+          $ libtool        exe     --dry-run gdb prog.exe
+          $ libtool        e       --dry-run gdb prog.exe
+
+     MODE must be set to one of the following:
+
+    `compile'
+          Compile a source file into a libtool object.
+
+    `execute'
+          Automatically set the library path so that another program
+          can use uninstalled libtool-generated programs or libraries.
+
+    `link'
+          Create a library or an executable.
+
+    `install'
+          Install libraries or executables.
+
+    `finish'
+          Complete the installation of libtool libraries on the system.
+
+    `uninstall'
+          Delete installed libraries or executables.
+
+    `clean'
+          Delete uninstalled libraries or executables.
+
+`--tag=TAG'
+     Use configuration variables from tag TAG (*note Tags::).
+
+`--preserve-dup-deps'
+     Do not remove duplicate dependencies in libraries.  When building
+     packages with static libraries, the libraries may depend
+     circularly on each other (shared libs can too, but for those it
+     doesn't matter), so there are situations, where -la -lb -la is
+     required, and the second -la may not be stripped or the link will
+     fail.  In cases where these duplications are required, this option
+     will preserve them, only stripping the libraries that libtool
+     knows it can safely.
+
+`--quiet'
+`--silent'
+     Do not print out any progress or informational messages.
+
+`-v'
+`--verbose'
+     Print out progress and informational messages (enabled by default),
+     as well as additional messages not ordinary seen by default.
+
+`--no-quiet'
+`--no-silent'
+     Print out the progress and informational messages that are seen by
+     default. This option has no effect on whether the additional
+     messages seen in `--verbose' mode are shown.
+
+`--no-verbose'
+     Do not print out any additional informational messages beyond
+     those ordinarily seen by default. This option has no effect on
+     whether the ordinary progress and informational messages enabled
+     by `--no-quiet' are shown.
+
+     Thus, there are now three different message levels (not counting
+     `--debug'), depending on whether the normal messages and/or the
+     additional verbose messages are displayed.  Note that there is no
+     mechanism to diplay verbose messages, without also displaying
+     normal messages.
+
+    *default*
+          Normal messages are displayed, verbose messages are not
+          displayed.  In addition to being the default mode, it can be
+          forcibly achieved by using both option `--no-verbose' and
+          either option `--no-silent' or option `--no-quiet'.
+
+    *silent*
+          Neither normal messages nor verbose messages are displayed.
+          This mode can be achieved using either option `--silent' or
+          option `--quiet'.
+
+    *verbose*
+          Both normal messages and verbose messages are displayed. This
+          mode can be achieved using either option `-v' or option
+          `--verbose'.
+
+`--version'
+     Print libtool version information and exit.
+
+   The current `libtool' implementation is done with a shell script
+that needs to be invoked by the shell which `configure' chose for
+configuring `libtool' (*note The Autoconf Manual:
+(autoconf)config.status Invocation.).  This shell is set in the
+she-bang (`#!') line of the `libtool' script.  Using a different shell
+may cause undefined behavior.
+
+   The MODE-ARGS are a variable number of arguments, depending on the
+selected operation mode.  In general, each MODE-ARG is interpreted by
+programs libtool invokes, rather than libtool itself.

+

+
+4.1 Compile mode
+================
+
+For "compile" mode, MODE-ARGS is a compiler command to be used in
+creating a "standard" object file.  These arguments should begin with
+the name of the C compiler, and contain the `-c' compiler flag so that
+only an object file is created.
+
+   Libtool determines the name of the output file by removing the
+directory component from the source file name, then substituting the
+source code suffix (e.g. `.c' for C source code) with the library
+object suffix, `.lo'.
+
+   If shared libraries are being built, any necessary PIC generation
+flags are substituted into the compilation command.
+
+   The following components of MODE-ARGS are treated specially:
+
+`-o'
+     Note that the `-o' option is now fully supported.  It is emulated
+     on the platforms that don't support it (by locking and moving the
+     objects), so it is really easy to use libtool, just with minor
+     modifications to your Makefiles.  Typing for example
+          libtool --mode=compile gcc -c foo/x.c -o foo/x.lo
+     will do what you expect.
+
+     Note, however, that, if the compiler does not support `-c' and
+     `-o', it is impossible to compile `foo/x.c' without overwriting an
+     existing `./x.o'.  Therefore, if you do have a source file
+     `./x.c', make sure you introduce dependencies in your `Makefile'
+     to make sure `./x.o' (or `./x.lo') is re-created after any
+     sub-directory's `x.lo':
+
+          x.o x.lo: foo/x.lo bar/x.lo
+
+     This will also ensure that make won't try to use a temporarily
+     corrupted `x.o' to create a program or library.  It may cause
+     needless recompilation on platforms that support `-c' and `-o'
+     together, but it's the only way to make it safe for those that
+     don't.
+
+`-no-suppress'
+     If both PIC and non-PIC objects are being built, libtool will
+     normally suppress the compiler output for the PIC object
+     compilation to save showing very similar, if not identical
+     duplicate output for each object.  If the `-no-suppress' option is
+     given in compile mode, libtool will show the compiler output for
+     both objects.
+
+`-prefer-pic'
+     Libtool will try to build only PIC objects.
+
+`-prefer-non-pic'
+     Libtool will try to build only non-PIC objects.
+
+`-shared'
+     Even if Libtool was configured with `--enable-static', the object
+     file Libtool builds will not be suitable for static linking.
+     Libtool will signal an error if it was configured with
+     `--disable-shared', or if the host does not support shared
+     libraries.
+
+`-static'
+     Even if libtool was configured with `--disable-static', the object
+     file Libtool builds *will* be suitable for static linking.
+
+`-Wc,FLAG'
+`-Xcompiler FLAG'
+     Pass a flag directly to the compiler.  With `-Wc,', multiple flags
+     may be separated by commas, whereas `-Xcompiler ' passes through
+     commas unchanged.

+
+4.2 Link mode
+=============
+
+"Link" mode links together object files (including library objects) to
+form another library or to create an executable program.
+
+   MODE-ARGS consist of a command using the C compiler to create an
+output file (with the `-o' flag) from several object files.
+
+   The following components of MODE-ARGS are treated specially:
+
+`-all-static'
+     If OUTPUT-FILE is a program, then do not link it against any
+     shared libraries at all.  If OUTPUT-FILE is a library, then only
+     create a static library.  In general, this flag cannot be used
+     together with `disable-static' (*note LT_INIT::).
+
+`-avoid-version'
+     Tries to avoid versioning (*note Versioning::) for libraries and
+     modules, i.e. no version information is stored and no symbolic
+     links are created.  If the platform requires versioning, this
+     option has no effect.
+
+`-bindir'
+     Pass the absolute name of the directory for installing executable
+     programs (*note Directory Variables: (standards)Directory
+     Variables.).  `libtool' may use this value to install shared
+     libraries there on systems that do not provide for any library
+     hardcoding and use the directory of a program and the `PATH'
+     variable as library search path.  This is typically used for DLLs
+     on Windows or other systems using the PE (Portable Executable)
+     format.  On other systems, `-bindir' is ignored.  The default
+     value used is `LIBDIR/../bin' for libraries installed to `LIBDIR'.
+     You should not use `-bindir' for modules.
+
+`-dlopen FILE'
+     Same as `-dlpreopen FILE', if native dlopening is not supported on
+     the host platform (*note Dlopened modules::) or if the program is
+     linked with `-static', `-static-libtool-libs', or `-all-static'.
+     Otherwise, no effect.  If FILE is `self' Libtool will make sure
+     that the program can `dlopen' itself, either by enabling
+     `-export-dynamic' or by falling back to `-dlpreopen self'.
+
+`-dlpreopen FILE'
+     Link FILE into the output program, and add its symbols to the list
+     of preloaded symbols (*note Dlpreopening::).  If FILE is `self',
+     the symbols of the program itself will be added to preloaded
+     symbol lists.  If FILE is `force' Libtool will make sure that a
+     preloaded symbol list is always _defined_, regardless of whether
+     it's empty or not.
+
+`-export-dynamic'
+     Allow symbols from OUTPUT-FILE to be resolved with `dlsym' (*note
+     Dlopened modules::).
+
+`-export-symbols SYMFILE'
+     Tells the linker to export only the symbols listed in SYMFILE.
+     The symbol file should end in `.sym' and must contain the name of
+     one symbol per line.  This option has no effect on some platforms.
+     By default all symbols are exported.
+
+`-export-symbols-regex REGEX'
+     Same as `-export-symbols', except that only symbols matching the
+     regular expression REGEX are exported.  By default all symbols are
+     exported.
+
+`-LLIBDIR'
+     Search LIBDIR for required libraries that have already been
+     installed.
+
+`-lNAME'
+     OUTPUT-FILE requires the installed library `libNAME'.  This option
+     is required even when OUTPUT-FILE is not an executable.
+
+`-module'
+     Creates a library that can be dlopened (*note Dlopened modules::).
+     This option doesn't work for programs.  Module names don't need to
+     be prefixed with `lib'.  In order to prevent name clashes,
+     however, `libNAME' and `NAME' must not be used at the same time in
+     your package.
+
+`-no-fast-install'
+     Disable fast-install mode for the executable OUTPUT-FILE.  Useful
+     if the program won't be necessarily installed.
+
+`-no-install'
+     Link an executable OUTPUT-FILE that can't be installed and
+     therefore doesn't need a wrapper script on systems that allow
+     hardcoding of library paths.  Useful if the program is only used
+     in the build tree, e.g., for testing or generating other files.
+
+`-no-undefined'
+     Declare that OUTPUT-FILE does not depend on any libraries other
+     than the ones listed on the command line, i.e., after linking, it
+     will not have unresolved symbols.  Some platforms require all
+     symbols in shared libraries to be resolved at library creation
+     (*note Inter-library dependencies::), and using this parameter
+     allows `libtool' to assume that this will not happen.
+
+`-o OUTPUT-FILE'
+     Create OUTPUT-FILE from the specified objects and libraries.
+
+`-objectlist FILE'
+     Use a list of object files found in FILE to specify objects.
+
+`-precious-files-regex REGEX'
+     Prevents removal of files from the temporary output directory whose
+     names match this regular expression.  You might specify `\.bbg?$'
+     to keep those files created with `gcc -ftest-coverage' for example.
+
+`-release RELEASE'
+     Specify that the library was generated by release RELEASE of your
+     package, so that users can easily tell which versions are newer
+     than others.  Be warned that no two releases of your package will
+     be binary compatible if you use this flag.  If you want binary
+     compatibility, use the `-version-info' flag instead (*note
+     Versioning::).
+
+`-rpath LIBDIR'
+     If OUTPUT-FILE is a library, it will eventually be installed in
+     LIBDIR.  If OUTPUT-FILE is a program, add LIBDIR to the run-time
+     path of the program.  On platforms that don't support hardcoding
+     library paths into executables and only search PATH for shared
+     libraries, such as when OUTPUT-FILE is a Windows (or other PE
+     platform) DLL, the `.la' control file will be installed in LIBDIR,
+     but see `-bindir' above for the eventual destination of the `.dll'
+     or other library file itself.
+
+`-R LIBDIR'
+     If OUTPUT-FILE is a program, add LIBDIR to its run-time path.  If
+     OUTPUT-FILE is a library, add `-RLIBDIR' to its DEPENDENCY_LIBS,
+     so that, whenever the library is linked into a program, LIBDIR
+     will be added to its run-time path.
+
+`-shared'
+     If OUTPUT-FILE is a program, then link it against any uninstalled
+     shared libtool libraries (this is the default behavior).  If
+     OUTPUT-FILE is a library, then only create a shared library.  In
+     the later case, libtool will signal an error if it was configured
+     with `--disable-shared', or if the host does not support shared
+     libraries.
+
+`-shrext SUFFIX'
+     If OUTPUT-FILE is a libtool library, replace the system's standard
+     file name extension for shared libraries with SUFFIX (most systems
+     use `.so' here).  This option is helpful in certain cases where an
+     application requires that shared libraries (typically modules)
+     have an extension other than the default one.  Please note you
+     must supply the full file name extension including any leading dot.
+
+`-static'
+     If OUTPUT-FILE is a program, then do not link it against any
+     uninstalled shared libtool libraries.  If OUTPUT-FILE is a
+     library, then only create a static library.
+
+`-static-libtool-libs'
+     If OUTPUT-FILE is a program, then do not link it against any
+     shared libtool libraries.  If OUTPUT-FILE is a library, then only
+     create a static library.
+
+`-version-info CURRENT[:REVISION[:AGE]]'
+     If OUTPUT-FILE is a libtool library, use interface version
+     information CURRENT, REVISION, and AGE to build it (*note
+     Versioning::).  Do *not* use this flag to specify package release
+     information, rather see the `-release' flag.
+
+`-version-number MAJOR[:MINOR[:REVISION]]'
+     If OUTPUT-FILE is a libtool library, compute interface version
+     information so that the resulting library uses the specified
+     major, minor and revision numbers.  This is designed to permit
+     libtool to be used with existing projects where identical version
+     numbers are already used across operating systems.  New projects
+     should use the `-version-info' flag instead.
+
+`-weak LIBNAME'
+     if OUTPUT-FILE is a libtool library, declare that it provides a
+     weak LIBNAME interface.  This is a hint to libtool that there is
+     no need to append LIBNAME to the list of dependency libraries of
+     OUTPUT-FILE, because linking against OUTPUT-FILE already supplies
+     the same interface (*note Linking with dlopened modules::).
+
+`-Wc,FLAG'
+`-Xcompiler FLAG'
+     Pass a linker-specific flag directly to the compiler.  With `-Wc,',
+     multiple flags may be separated by commas, whereas `-Xcompiler '
+     passes through commas unchanged.
+
+`-Wl,FLAG'
+`-Xlinker FLAG'
+     Pass a linker-specific flag directly to the linker.
+
+`-XCClinker FLAG'
+     Pass a link-specific flag to the compiler driver (`CC') during
+     linking.
+
+   If the OUTPUT-FILE ends in `.la', then a libtool library is created,
+which must be built only from library objects (`.lo' files).  The
+`-rpath' option is required.  In the current implementation, libtool
+libraries may not depend on other uninstalled libtool libraries (*note
+Inter-library dependencies::).
+
+   If the OUTPUT-FILE ends in `.a', then a standard library is created
+using `ar' and possibly `ranlib'.
+
+   If OUTPUT-FILE ends in `.o' or `.lo', then a reloadable object file
+is created from the input files (generally using `ld -r').  This method
+is often called "partial linking".
+
+   Otherwise, an executable program is created.

+
+4.3 Execute mode
+================
+
+For "execute" mode, the library path is automatically set, then a
+program is executed.
+
+   The first of the MODE-ARGS is treated as a program name, with the
+rest as arguments to that program.
+
+   The following components of MODE-ARGS are treated specially:
+
+`-dlopen FILE'
+     Add the directory containing FILE to the library path.
+
+   This mode sets the library path environment variable according to any
+`-dlopen' flags.
+
+   If any of the ARGS are libtool executable wrappers, then they are
+translated into the name of their corresponding uninstalled binary, and
+any of their required library directories are added to the library path.
+
+
+File: libtool.info,  Node: Install mode,  Next: Finish mode,  Prev: Execute mode,  Up: Invoking libtool
+
+4.4 Install mode
+================
+
+In "install" mode, libtool interprets most of the elements of MODE-ARGS
+as an installation command beginning with `cp', or a BSD-compatible
+`install' program.
+
+   The following components of MODE-ARGS are treated specially:
+
+`-inst-prefix-dir INST-PREFIX-DIR'
+     When installing into a temporary staging area, rather than the
+     final `prefix', this argument is used to reflect the temporary
+     path, in much the same way `automake' uses `DESTDIR'.  For
+     instance, if `prefix' is `/usr/local', but INST-PREFIX-DIR is
+     `/tmp', then the object will be installed under `/tmp/usr/local/'.
+     If the installed object is a libtool library, then the internal
+     fields of that library will reflect only `prefix', not
+     INST-PREFIX-DIR:
+
+          # Directory that this library needs to be installed in:
+          libdir='/usr/local/lib'
+
+     not
+
+          # Directory that this library needs to be installed in:
+          libdir='/tmp/usr/local/lib'
+
+     `inst-prefix' is also used to insure that if the installed object
+     must be relinked upon installation, that it is relinked against
+     the libraries in INST-PREFIX-DIR/`prefix', not `prefix'.
+
+     In truth, this option is not really intended for use when calling
+     libtool directly; it is automatically used when `libtool
+     --mode=install' calls `libtool --mode=relink'.  Libtool does this
+     by analyzing the destination path given in the original `libtool
+     --mode=install' command and comparing it to the expected
+     installation path established during `libtool --mode=link'.
+
+     Thus, end-users need change nothing, and `automake'-style `make
+     install DESTDIR=/tmp' will Just Work(tm) most of the time.  For
+     systems where fast installation can not be turned on, relinking
+     may be needed.  In this case, a `DESTDIR' install will fail.
+
+     Currently it is not generally possible to install into a temporary
+     staging area that contains needed third-party libraries which are
+     not yet visible at their final location.
+
+   The rest of the MODE-ARGS are interpreted as arguments to the `cp'
+or `install' command.
+
+   The command is run, and any necessary unprivileged post-installation
+commands are also completed.

+File: libtool.info,  Node: Finish mode,  Next: Uninstall mode,  Prev: Install mode,  Up: Invoking libtool
+
+4.5 Finish mode
+===============
+
+"Finish" mode has two functions.  One is to help system administrators
+install libtool libraries so that they can be located and linked into
+user programs.  To invoke this functionality, pass the name of a library
+directory as MODE-ARG.  Running this command may require superuser
+privileges, and the `--dry-run' option may be useful.
+
+   The second is to facilitate transferring libtool libraries to a
+native compilation environment after they were built in a
+cross-compilation environment.  Cross-compilation environments may rely
+on recent libtool features, and running libtool in finish mode will
+make it easier to work with older versions of libtool.  This task is
+performed whenever the MODE-ARG is a `.la' file.

+5 Integrating libtool with your package
+***************************************
+
+This chapter describes how to integrate libtool with your packages so
+that your users can install hassle-free shared libraries.
+
+   There are several ways in which Libtool may be integrated in your
+package, described in the following sections.  Typically, the Libtool
+macro files as well as `ltmain.sh' are copied into your package using
+`libtoolize' and `aclocal' after setting up the `configure.ac' and
+toplevel `Makefile.am', then `autoconf' adds the needed tests to the
+`configure' script.  These individual steps are often automated with
+`autoreconf'.
+
+   Here is a diagram showing how such a typical Libtool configuration
+works when preparing a package for distribution, assuming that `m4' has
+been chosen as location for additional Autoconf macros, and `build-aux'
+as location for auxiliary build tools (*note The Autoconf Manual:
+(autoconf)Input.):
+
+     libtool.m4 -----.                .--> aclocal.m4 -----.
+     ltoptions.m4 ---+  .-> aclocal* -+                    +--> autoconf*
+     ltversion.m4 ---+--+             `--> [copy in m4/] --+       |
+     ltsugar.m4 -----+  |                    ^             |       \/
+     lt~obsolete.m4 -+  +-> libtoolize* -----'             |    configure
+     [ltdl.m4] ------+  |                                  |
+                        `----------------------------------'
+
+     ltmain.sh -----------> libtoolize* -> [copy in build-aux/]
+
+   During configuration, the `libtool' script is generated either
+through `config.status' or `config.lt':
+
+                  .--> config.status* --.
+     configure* --+                     +--> libtool
+                  `--> [config.lt*] ----'      ^
+                                               |
+     ltmain.sh --------------------------------'
+
+   At `make' run time, `libtool' is then invoked as needed as a wrapper
+around compilers, linkers, install and cleanup programs.
+
+   There are alternatives choices to several parts of the setup; for
+example, the Libtool macro files can either be copied or symlinked into
+the package, or copied into `aclocal.m4'.  As another example, an
+external, pre-configured `libtool' script may be used, by-passing most
+of the tests and package-specific setup for Libtool.

+
+5.1 Autoconf macros exported by libtool
+=======================================
+
+Libtool uses a number of macros to interrogate the host system when it
+is being built, and you can use some of them yourself too.  Although
+there are a great many other macros in the libtool installed m4 files,
+these do not form part of the published interface, and are subject to
+change between releases.
+
+Macros in the `LT_CMD_' namespace check for various shell commands:
+
+ -- Macro: LT_CMD_MAX_LEN
+     Finds the longest command line that can be safely passed to
+     `$SHELL' without being truncated, and store in the shell variable
+     `$max_cmd_len'.  It is only an approximate value, but command
+     lines of this length or shorter are guaranteed not to be truncated.
+
+Macros in the `LT_FUNC_' namespace check characteristics of library
+functions:
+
+ -- Macro: LT_FUNC_DLSYM_USCORE
+     `AC_DEFINE' the preprocessor symbol `DLSYM_USCORE' if we have to
+     add an underscore to symbol-names passed in to `dlsym'.
+
+Macros in the `LT_LIB_' namespace check characteristics of system
+libraries:
+
+ -- Macro: LT_LIB_M
+     Set `LIBM' to the math library or libraries required on this
+     machine, if any.
+
+ -- Macro: LT_LIB_DLLOAD
+     This is the macro used by `libltdl' to determine which dlloaders
+     to use on this machine, if any.  Several shell variables are set
+     (and `AC_SUBST'ed) depending on the dlload interfaces are
+     available on this machine.  `LT_DLLOADERS' contains a list of
+     libtool libraries that can be used, and if necessary also sets
+     `LIBADD_DLOPEN' if additional system libraries are required by the
+     `dlopen' loader, and `LIBADD_SHL_LOAD' if additional system
+     libraries are required by the `shl_load' loader, respectively.
+     Finally some symbols are set in `config.h' depending on the
+     loaders that are found to work: `HAVE_LIBDL', `HAVE_SHL_LOAD',
+     `HAVE_DYLD', `HAVE_DLD'.
+
+Macros in the `LT_PATH_' namespace search the system for the full path
+to particular system commands:
+
+ -- Macro: LT_PATH_LD
+     Add a `--with-gnu-ld' option to `configure'.  Try to find the path
+     to the linker used by `$CC', and whether it is the GNU linker.
+     The result is stored in the shell variable `$LD', which is
+     `AC_SUBST'ed.
+
+ -- Macro: LT_PATH_NM
+     Try to find a BSD-compatible `nm' or a MS-compatible `dumpbin'
+     command on this machine.  The result is stored in the shell
+     variable `$NM', which is `AC_SUBST'ed.
+
+Macros in the `LT_SYS_' namespace probe for system characteristics:
+
+ -- Macro: LT_SYS_DLOPEN_SELF
+     Tests whether a program can dlopen itself, and then also whether
+     the same program can still dlopen itself when statically linked.
+     Results are stored in the shell variables `$enable_dlopen_self' and

+
+ -- Macro: LT_SYS_DLOPEN_DEPLIBS
+     Define the preprocessor symbol `LTDL_DLOPEN_DEPLIBS' if the OS

+     equivalent).
+
+ -- Macro: LT_SYS_DLSEARCH_PATH
+     Define the preprocessor symbol `LT_DLSEARCH_PATH' to the system
+     default library search path.
+
+ -- Macro: LT_SYS_MODULE_EXT
+     Define the preprocessor symbol `LT_MODULE_EXT' to the extension
+     used for runtime loadable modules.  If you use libltdl to open
+     modules, then you can simply use the libtool library extension,
+     `.la'.
+
+ -- Macro: LT_SYS_MODULE_PATH
+     Define the preprocessor symbol `LT_MODULE_PATH_VAR' to the name of
+     the shell environment variable that determines the run-time module
+     search path.
+
+ -- Macro: LT_SYS_SYMBOL_USCORE
+     Set the shell variable `sys_symbol_underscore' to `no' unless the

+
+5.2 Writing `Makefile' rules for libtool
+========================================
+
+Libtool is fully integrated with Automake (*note Introduction:
+(automake)Top.), starting with Automake version 1.2.
+
+   If you want to use libtool in a regular `Makefile' (or
+`Makefile.in'), you are on your own.  If you're not using Automake, and
+you don't know how to incorporate libtool into your package you need to
+do one of the following:
+
+  1. Download the latest Automake distribution from your nearest GNU
+     mirror, install it, and start using it.
+
+  2. Learn how to write `Makefile' rules by hand.  They're sometimes
+     complex, but if you're clever enough to write rules for compiling
+     your old libraries, then you should be able to figure out new
+     rules for libtool libraries (hint: examine the `Makefile.in' in
+     the `tests/demo' subdirectory of the libtool distribution... note
+     especially that it was automatically generated from the
+     `Makefile.am' by Automake).
+
+
+File: libtool.info,  Node: Using Automake,  Next: Configuring,  Prev: Makefile rules,  Up: Integrating libtool
+
+5.3 Using Automake with libtool
+===============================
+
+Libtool library support is implemented under the `LTLIBRARIES' primary.
+
+   Here are some samples from the Automake `Makefile.am' in the libtool
+distribution's `demo' subdirectory.
+
+   First, to link a program against a libtool library, just use the
+`program_LDADD'(1) variable:
+
+     bin_PROGRAMS = hell hell_static
+
+     # Build hell from main.c and libhello.la
+     hell_SOURCES = main.c
+     hell_LDADD = libhello.la
+
+     # Create a statically linked version of hell.
+     hell_static_SOURCES = main.c
+     hell_static_LDADD = libhello.la
+     hell_static_LDFLAGS = -static
+
+   You may use the `program_LDFLAGS' variable to stuff in any flags you
+want to pass to libtool while linking `program' (such as `-static' to
+avoid linking uninstalled shared libtool libraries).
+
+   Building a libtool library is almost as trivial... note the use of
+`libhello_la_LDFLAGS' to pass the `-version-info' (*note Versioning::)
+option to libtool:
+
+     # Build a libtool library, libhello.la for installation in libdir.
+     lib_LTLIBRARIES = libhello.la
+     libhello_la_SOURCES = hello.c foo.c
+     libhello_la_LDFLAGS = -version-info 3:12:1
+
+   The `-rpath' option is passed automatically by Automake (except for
+libraries listed as `noinst_LTLIBRARIES'), so you should not specify it.
+
+   *Note Building a Shared Library: (automake)A Shared Library, for
+more information.
+
+   ---------- Footnotes ----------
+
+   (1) Since GNU Automake 1.5, the flags `-dlopen' or `-dlpreopen'
+(*note Link mode::) can be employed with the `program_LDADD' variable.
+Unfortunately, older releases didn't accept these flags, so if you are
+stuck with an ancient Automake, we recommend quoting the flag itself,
+and setting `program_DEPENDENCIES' too:
+
+     program_LDADD = "-dlopen" libfoo.la
+     program_DEPENDENCIES = libfoo.la

+
+5.4 Configuring libtool
+=======================
+
+Libtool requires intimate knowledge of your compiler suite and operating
+system in order to be able to create shared libraries and link against
+them properly.  When you install the libtool distribution, a
+system-specific libtool script is installed into your binary directory.
+
+   However, when you distribute libtool with your own packages (*note
+Distributing::), you do not always know the compiler suite and
+operating system that are used to compile your package.
+
+   For this reason, libtool must be "configured" before it can be used.
+This idea should be familiar to anybody who has used a GNU `configure'
+script.  `configure' runs a number of tests for system features, then
+generates the `Makefile's (and possibly a `config.h' header file),
+after which you can run `make' and build the package.
+
+   Libtool adds its own tests to your `configure' script in order to
+generate a libtool script for the installer's host machine.
+
+* Menu:
+
+* LT_INIT::                     Configuring `libtool' in `configure.ac'.
+* Configure notes::             Platform-specific notes for configuration.

+
+5.4.1 The `LT_INIT' macro
+-------------------------
+
+If you are using GNU Autoconf (or Automake), you should add a call to
+`LT_INIT' to your `configure.ac' file.  This macro adds many new tests
+to the `configure' script so that the generated libtool script will
+understand the characteristics of the host.  It's the most important of
+a number of macros defined by Libtool:
+
+ -- Macro: LT_PREREQ (VERSION)
+     Ensure that a recent enough version of Libtool is being used.  If
+     the version of Libtool used for `LT_INIT' is earlier than VERSION,
+     print an error message to the standard error output and exit with
+     failure (exit status is 63).  For example:
+
+          LT_PREREQ([2.4.2])
+
+ -- Macro: LT_INIT (OPTIONS)
+ -- Macro: AC_PROG_LIBTOOL
+ -- Macro: AM_PROG_LIBTOOL
+     Add support for the `--enable-shared', `--disable-shared',
+     `--enable-static', `--disable-static', `--with-pic', and
+     `--without-pic' `configure' flags.(1)  `AC_PROG_LIBTOOL' and
+     `AM_PROG_LIBTOOL' are deprecated names for older versions of this
+     macro; `autoupdate' will upgrade your `configure.ac' files.
+
+     By default, this macro turns on shared libraries if they are
+     available, and also enables static libraries if they don't
+     conflict with the shared libraries.  You can modify these defaults
+     by passing either `disable-shared' or `disable-static' in the
+     option list to `LT_INIT', or using `AC_DISABLE_SHARED' or
+     `AC_DISABLE_STATIC'.
+
+          # Turn off shared libraries during beta-testing, since they
+          # make the build process take too long.
+          LT_INIT([disable-shared])
+
+     The user may specify modified forms of the configure flags
+     `--enable-shared' and `--enable-static' to choose whether shared
+     or static libraries are built based on the name of the package.
+     For example, to have shared `bfd' and `gdb' libraries built, but
+     not shared `libg++', you can run all three `configure' scripts as
+     follows:
+
+          trick$ ./configure --enable-shared=bfd,gdb
+
+     In general, specifying `--enable-shared=PKGS' is the same as
+     configuring with `--enable-shared' every package named in the
+     comma-separated PKGS list, and every other package with
+     `--disable-shared'.  The `--enable-static=PKGS' flag behaves
+     similarly, but it uses `--enable-static' and `--disable-static'.
+     The same applies to the `--enable-fast-install=PKGS' flag, which
+     uses `--enable-fast-install' and `--disable-fast-install'.
+
+     The package name `default' matches any packages that have not set
+     their name in the `PACKAGE' environment variable.
+
+     The `--with-pic' and `--without-pic' configure flags can be used
+     to specify whether or not `libtool' uses PIC objects.  By default,
+     `libtool' uses PIC objects for shared libraries and non-PIC
+     objects for static libraries.  The `--with-pic' option also
+     accepts a comma-separated list of package names.  Specifying
+     `--with-pic=PKGS' is the same as configuring every package in PKGS
+     with `--with-pic' and every other package with the default
+     configuration.  The package name `default' is treated the same as
+     for `--enable-shared' and `--enable-static'.
+
+     This macro also sets the shell variable `LIBTOOL_DEPS', that you
+     can use to automatically update the libtool script if it becomes
+     out-of-date.  In order to do that, add to your `configure.ac':
+
+          LT_INIT
+          AC_SUBST([LIBTOOL_DEPS])
+
+     and, to `Makefile.in' or `Makefile.am':
+
+          LIBTOOL_DEPS = @LIBTOOL_DEPS@
+          libtool: $(LIBTOOL_DEPS)
+                  $(SHELL) ./config.status libtool
+
+     If you are using GNU Automake, you can omit the assignment, as
+     Automake will take care of it.  You'll obviously have to create
+     some dependency on `libtool'.
+
+     Aside from `disable-static' and `disable-shared', there are other
+     options that you can pass to `LT_INIT' to modify its behaviour.
+     Here is a full list:
+
+    `dlopen'
+          Enable checking for dlopen support.  This option should be
+          used if the package makes use of the `-dlopen' and
+          `-dlpreopen' libtool flags, otherwise libtool will assume
+          that the system does not support dlopening.
+
+    `win32-dll'
+          This option should be used if the package has been ported to
+          build clean dlls on win32 platforms.  Usually this means that
+          any library data items are exported with
+          `__declspec(dllexport)' and imported with
+          `__declspec(dllimport)'.  If this macro is not used, libtool
+          will assume that the package libraries are not dll clean and
+          will build only static libraries on win32 hosts.
+
+          Provision must be made to pass `-no-undefined' to `libtool'
+          in link mode from the package `Makefile'.  Naturally, if you
+          pass `-no-undefined', you must ensure that all the library
+          symbols *really are* defined at link time!
+
+    `disable-fast-install'
+          Change the default behaviour for `LT_INIT' to disable
+          optimization for fast installation.  The user may still
+          override this default, depending on platform support, by
+          specifying `--enable-fast-install' to `configure'.
+
+    `shared'
+          Change the default behaviour for `LT_INIT' to enable shared
+          libraries.  This is the default on all systems where Libtool
+          knows how to create shared libraries.  The user may still
+          override this default by specifying `--disable-shared' to
+          `configure'.
+
+    `disable-shared'
+          Change the default behaviour for `LT_INIT' to disable shared
+          libraries.  The user may still override this default by
+          specifying `--enable-shared' to `configure'.
+
+    `static'
+          Change the default behaviour for `LT_INIT' to enable static
+          libraries.  This is the default on all systems where shared
+          libraries have been disabled for some reason, and on most
+          systems where shared libraries have been enabled.  If shared
+          libraries are enabled, the user may still override this
+          default by specifying `--disable-static' to `configure'.
+
+    `disable-static'
+          Change the default behaviour for `LT_INIT' to disable static
+          libraries.  The user may still override this default by
+          specifying `--enable-static' to `configure'.
+
+    `pic-only'
+          Change the default behaviour for `libtool' to try to use only
+          PIC objects.  The user may still override this default by
+          specifying `--without-pic' to `configure'.
+
+    `no-pic'
+          Change the default behaviour of `libtool' to try to use only
+          non-PIC objects.  The user may still override this default by
+          specifying `--with-pic' to `configure'.
+
+
+
+ -- Macro: LT_LANG (LANGUAGE)
+     Enable `libtool' support for the language given if it has not yet
+     already been enabled.  Languages accepted are "C++", "Fortran 77",
+     "Java", "Go", and "Windows Resource".
+
+     If Autoconf language support macros such as `AC_PROG_CXX' are used
+     in your `configure.ac', Libtool language support will automatically
+     be enabled.
+
+     Conversely using `LT_LANG' to enable language support for Libtool
+     will automatically enable Autoconf language support as well.
+
+     Both of the following examples are therefore valid ways of adding
+     C++ language support to Libtool.
+
+          LT_INIT
+          LT_LANG([C++])
+
+          LT_INIT
+          AC_PROG_CXX
+
+
+ -- Macro: AC_LIBTOOL_DLOPEN
+     This macro is deprecated, the `dlopen' option to `LT_INIT' should
+     be used instead.
+
+ -- Macro: AC_LIBTOOL_WIN32_DLL
+     This macro is deprecated, the `win32-dll' option to `LT_INIT'
+     should be used instead.
+
+ -- Macro: AC_DISABLE_FAST_INSTALL
+     This macro is deprecated, the `disable-fast-install' option to
+     `LT_INIT' should be used instead.
+
+ -- Macro: AC_DISABLE_SHARED
+ -- Macro: AM_DISABLE_SHARED
+     Change the default behaviour for `LT_INIT' to disable shared
+     libraries.  The user may still override this default by specifying
+     `--enable-shared'.  The option `disable-shared' to `LT_INIT' is a
+     shorthand for this.  `AM_DISABLE_SHARED' is a deprecated alias for
+     `AC_DISABLE_SHARED'.
+
+ -- Macro: AC_ENABLE_SHARED
+ -- Macro: AM_ENABLE_SHARED
+     Change the default behaviour for `LT_INIT' to enable shared
+     libraries.  This is the default on all systems where Libtool knows
+     how to create shared libraries.  The user may still override this
+     default by specifying `--disable-shared'.  The option `shared' to
+     `LT_INIT' is a shorthand for this.  `AM_ENABLE_SHARED' is a
+     deprecated alias for `AC_ENABLE_SHARED'.
+
+ -- Macro: AC_DISABLE_STATIC
+ -- Macro: AM_DISABLE_STATIC
+     Change the default behaviour for `LT_INIT' to disable static
+     libraries.  The user may still override this default by specifying
+     `--enable-static'.  The option `disable-static' to `LT_INIT' is a
+     shorthand for this.  `AM_DISABLE_STATIC' is a deprecated alias for
+     `AC_DISABLE_STATIC'.
+
+ -- Macro: AC_ENABLE_STATIC
+ -- Macro: AM_ENABLE_STATIC
+     Change the default behaviour for `LT_INIT' to enable static
+     libraries.  This is the default on all systems where shared
+     libraries have been disabled for some reason, and on most systems
+     where shared libraries have been enabled.  If shared libraries are
+     enabled, the user may still override this default by specifying
+     `--disable-static'.  The option `static' to `LT_INIT' is a
+     shorthand for this.  `AM_ENABLE_STATIC' is a deprecated alias for
+     `AC_ENABLE_STATIC'.
+
+   The tests in `LT_INIT' also recognize the following environment
+variables:
+
+ -- Variable: CC
+     The C compiler that will be used by the generated `libtool'.  If
+     this is not set, `LT_INIT' will look for `gcc' or `cc'.
+
+ -- Variable: CFLAGS
+     Compiler flags used to generate standard object files.  If this is
+     not set, `LT_INIT' will not use any such flags.  It affects only
+     the way `LT_INIT' runs tests, not the produced `libtool'.
+
+ -- Variable: CPPFLAGS
+     C preprocessor flags.  If this is not set, `LT_INIT' will not use
+     any such flags.  It affects only the way `LT_INIT' runs tests, not
+     the produced `libtool'.
+
+ -- Variable: LD
+     The system linker to use (if the generated `libtool' requires one).
+     If this is not set, `LT_INIT' will try to find out what is the
+     linker used by `CC'.
+
+ -- Variable: LDFLAGS
+     The flags to be used by `libtool' when it links a program.  If
+     this is not set, `LT_INIT' will not use any such flags.  It
+     affects only the way `LT_INIT' runs tests, not the produced
+     `libtool'.
+
+ -- Variable: LIBS
+     The libraries to be used by `LT_INIT' when it links a program.  If
+     this is not set, `LT_INIT' will not use any such flags.  It
+     affects only the way `LT_INIT' runs tests, not the produced
+     `libtool'.
+
+ -- Variable: NM
+     Program to use rather than checking for `nm'.
+
+ -- Variable: RANLIB
+     Program to use rather than checking for `ranlib'.
+
+ -- Variable: LN_S
+     A command that creates a link of a program, a soft-link if
+     possible, a hard-link otherwise.  `LT_INIT' will check for a
+     suitable program if this variable is not set.
+
+ -- Variable: DLLTOOL
+     Program to use rather than checking for `dlltool'.  Only meaningful
+     for Cygwin/MS-Windows.
+
+ -- Variable: OBJDUMP
+     Program to use rather than checking for `objdump'.  Only meaningful
+     for Cygwin/MS-Windows.
+
+ -- Variable: AS
+     Program to use rather than checking for `as'.  Only used on
+     Cygwin/MS-Windows at the moment.
+
+ -- Variable: MANIFEST_TOOL
+     Program to use rather than checking for `mt', the Manifest Tool.
+     Only used on Cygwin/MS-Windows at the moment.
+
+   With 1.3 era libtool, if you wanted to know any details of what
+libtool had discovered about your architecture and environment, you had
+to run the script with `--config' and grep through the results.  This
+idiom was supported up to and including 1.5.x era libtool, where it was
+possible to call the generated libtool script from `configure.ac' as
+soon as `LT_INIT' had completed.  However, one of the features of
+libtool 1.4 was that the libtool configuration was migrated out of a
+separate `ltconfig' file, and added to the `LT_INIT' macro (nee
+`AC_PROG_LIBTOOL'), so the results of the configuration tests were
+available directly to code in `configure.ac', rendering the call out to
+the generated libtool script obsolete.
+
+   Starting with libtool 2.0, the multipass generation of the libtool
+script has been consolidated into a single `config.status' pass, which
+happens after all the code in `configure.ac' has completed.  The
+implication of this is that the libtool script does not exist during
+execution of code from `configure.ac', and so obviously it cannot be
+called for `--config' details anymore.  If you are upgrading projects
+that used this idiom to libtool 2.0 or newer, you should replace those
+calls with direct references to the equivalent Autoconf shell variables
+that are set by the configure time tests before being passed to
+`config.status' for inclusion in the generated libtool script.
+
+ -- Macro: LT_OUTPUT
+     By default, the configured `libtool' script is generated by the
+     call to `AC_OUTPUT' command, and there is rarely any need to use
+     `libtool' from `configure'.  However, sometimes it is necessary to
+     run configure time compile and link tests using `libtool'.  You
+     can add `LT_OUTPUT' to your `configure.ac' any time after
+     `LT_INIT' and any `LT_LANG' calls; that done, `libtool' will be
+     created by a specially generated `config.lt' file, and available
+     for use in later tests.
+
+     Also, when `LT_OUTPUT' is used, for backwards compatibility with
+     Automake regeneration rules, `config.status' will call `config.lt'
+     to regenerate `libtool', rather than generating the file itself.
+
+   When you invoke the `libtoolize' program (*note Invoking
+libtoolize::), it will tell you where to find a definition of
+`LT_INIT'.  If you use Automake, the `aclocal' program will
+automatically add `LT_INIT' support to your `configure' script when it
+sees the invocation of `LT_INIT' in `configure.ac'.
+
+   Because of these changes, and the runtime version compatibility
+checks Libtool now executes, we now advise *against* including a copy of
+`libtool.m4' (and brethren) in `acinclude.m4'.  Instead, you should set
+your project macro directory with `AC_CONFIG_MACRO_DIR'.  When you
+`libtoolize' your project, a copy of the relevant macro definitions
+will be placed in your `AC_CONFIG_MACRO_DIR', where `aclocal' can
+reference them directly from `aclocal.m4'.
+
+   ---------- Footnotes ----------
+
+   (1) `LT_INIT' requires that you define the `Makefile' variable
+`top_builddir' in your `Makefile.in'.  Automake does this
+automatically, but Autoconf users should set it to the relative path to
+the top of your build directory (`../..', for example).

+
+5.4.2 Platform-specific configuration notes
+-------------------------------------------
+
+While Libtool tries to hide as many platform-specific features as
+possible, some have to be taken into account when configuring either
+the Libtool package or a libtoolized package.
+
+   * You currently need GNU make to build the Libtool package itself.
+
+   * On AIX there are two different styles of shared linking, one in
+     which symbols are bound at link-time and one in which symbols are
+     bound at runtime only, similar to ELF.  In case of doubt use
+     `LDFLAGS=-Wl,-brtl' for the latter style.
+
+   * On AIX, native tools are to be preferred over binutils; especially
+     for C++ code, if using the AIX Toolbox GCC 4.0 and binutils,
+     configure with `AR=/usr/bin/ar LD=/usr/bin/ld NM='/usr/bin/nm -B''.
+
+   * On AIX, the `/bin/sh' is very slow due to its inefficient handling
+     of here-documents.  A modern shell is preferable:
+          CONFIG_SHELL=/bin/bash; export $CONFIG_SHELL
+          $CONFIG_SHELL ./configure [...]
+
+   * For C++ code with templates, it may be necessary to specify the
+     way the compiler will generate the instantiations.  For Portland
+     pgCC version5, use `CXX='pgCC --one_instantiation_per_object'' and
+     avoid parallel `make'.
+
+   * On Darwin, for C++ code with templates you need two level shared
+     libraries.  Libtool builds these by default if
+     `MACOSX_DEPLOYMENT_TARGET' is set to 10.3 or later at `configure'
+     time.  See `rdar://problem/4135857' for more information on this
+     issue.
+
+   * The default shell on UNICOS 9, a ksh 88e variant, is too buggy to
+     correctly execute the libtool script.  Users are advised to
+     install a modern shell such as GNU bash.
+
+   * Some HP-UX `sed' programs are horribly broken, and cannot handle
+     libtool's requirements, so users may report unusual problems.
+     There is no workaround except to install a working `sed' (such as
+     GNU sed) on these systems.
+
+   * The vendor-distributed NCR MP-RAS `cc' programs emits copyright on
+     standard error that confuse tests on size of `conftest.err'.  The
+     workaround is to specify `CC' when run configure with `CC='cc
+     -Hnocopyr''.
+
+   * Any earlier DG/UX system with ELF executables, such as R3.10 or
+     R4.10, is also likely to work, but hasn't been explicitly tested.
+
+   * On Reliant Unix libtool has only been tested with the Siemens
+     C-compiler and an old version of `gcc' provided by Marco Walther.
+
+   * `libtool.m4', `ltdl.m4' and the `configure.ac' files are marked to
+     use autoconf-mode, which is distributed with GNU Emacs 21,
+     Autoconf itself, and all recent releases of XEmacs.
+
+   * When building on some GNU/Linux systems for multilib targets
+     `libtool' sometimes guesses the wrong paths that the linker and
+     dynamic linker search by default. If this occurs, you may override
+     libtool's guesses at `configure' time by setting the `autoconf'
+     cache variables `lt_cv_sys_lib_search_path_spec' and
+     `lt_cv_sys_lib_dlsearch_path_spec' respectively to the correct
+     search paths.

+=====================================
+
+In order to use libtool, you need to include the following files with
+your package:

+     Attempt to guess a canonical system name.
+
+`config.sub'
+     Canonical system name validation subroutine script.
+
+`install-sh'
+     BSD-compatible `install' replacement script.
+
+`ltmain.sh'
+     A generic script implementing basic libtool functionality.
+
+   Note that the libtool script itself should _not_ be included with
+your package.  *Note Configuring::.
+
+   You should use the `libtoolize' program, rather than manually
+copying these files into your package.

+
+5.5.1 Invoking `libtoolize'
+---------------------------
+
+The `libtoolize' program provides a standard way to add libtool support
+to your package.  In the future, it may implement better usage
+checking, or other features to make libtool even easier to use.
+
+   The `libtoolize' program has the following synopsis:
+
+     libtoolize [OPTION]...
+
+and accepts the following options:
+
+`--copy'
+`-c'
+     Copy files from the libtool data directory rather than creating
+     symlinks.
+
+`--debug'
+     Dump a trace of shell script execution to standard output.  This
+     produces a lot of output, so you may wish to pipe it to `less' (or
+     `more') or redirect to a file.
+
+`--dry-run'
+`-n'
+     Don't run any commands that modify the file system, just print them
+     out.
+
+`--force'
+`-f'
+     Replace existing libtool files.  By default, `libtoolize' won't
+     overwrite existing files.
+
+`--help'
+     Display a help message and exit.
+
+`--ltdl [TARGET-DIRECTORY-NAME]'
+     Install libltdl in the TARGET-DIRECTORY-NAME subdirectory of your
+     package.  Normally, the directory is extracted from the argument
+     to `LT_CONFIG_LTDL_DIR' in `configure.ac', though you can also
+     specify a subdirectory name here if you are not using Autoconf for
+     example.  If `libtoolize' can't determine the target directory,
+     `libltdl' is used as the default.
+
+`--no-warn'
+     Normally, Libtoolize tries to diagnose use of deprecated libtool
+     macros and other stylistic issues.  If you are deliberately using
+     outdated calling conventions, this option prevents Libtoolize from
+     explaining how to update your project's Libtool conventions.
+
+`--nonrecursive'
+     If passed in conjunction with `--ltdl', this option will cause the
+     `libltdl' installed by `libtoolize' to be set up for use with a
+     non-recursive `automake' build.  To make use of it, you will need
+     to add the following to the `Makefile.am' of the parent project:
+
+          ## libltdl/Makefile.inc appends to the following variables
+          ## so we set them here before including it:
+          BUILT_SOURCES   =
+
+          AM_CPPFLAGS        =
+          AM_LDFLAGS         =
+
+          include_HEADERS    =
+          noinst_LTLIBRARIES =
+          lib_LTLIBRARIES   =
+          EXTRA_LTLIBRARIES  =
+
+          EXTRA_DIST   =
+
+          CLEANFILES   =
+          MOSTLYCLEANFILES   =
+
+          include libltdl/Makefile.inc
+
+
+`--quiet'
+`-q'
+     Work silently.  `libtoolize --quiet' is used by GNU Automake to
+     add libtool files to your package if necessary.
+
+`--recursive'
+     If passed in conjunction with `--ltdl', this option will cause the
+     `libtoolize' installed `libltdl' to be set up for use with a
+     recursive `automake' build.  To make use of it, you will need to
+     adjust the parent project's `configure.ac':
+
+          AC_CONFIG_FILES([libltdl/Makefile])
+
+     and `Makefile.am':
+
+          SUBDIRS += libltdl
+
+`--subproject'
+     If passed in conjunction with `--ltdl', this option will cause the
+     `libtoolize' installed `libltdl' to be set up for independent
+     configuration and compilation as a self-contained subproject.  To
+     make use of it, you should arrange for your build to call
+     `libltdl/configure', and then run `make' in the `libltdl'
+     directory (or the subdirectory you put libltdl into).  If your
+     project uses Autoconf, you can use the supplied `LT_WITH_LTDL'
+     macro, or else call `AC_CONFIG_SUBDIRS' directly.
+
+     Previous releases of `libltdl' built exclusively in this mode, but
+     now it is the default mode both for backwards compatibility and
+     because, for example, it is suitable for use in projects that wish
+     to use `libltdl', but not use the Autotools for their own build
+     process.
+
+`--verbose'
+`-v'
+     Work noisily!  Give a blow by blow account of what `libtoolize' is
+     doing.
+
+`--version'
+     Print `libtoolize' version information and exit.
+
+   Sometimes it can be useful to pass options to `libtoolize' even
+though it is called by another program, such as `autoreconf'.  A
+limited number of options are parsed from the environment variable
+`LIBTOOLIZE_OPTIONS': currently `--debug', `--no-warn', `--quiet' and
+`--verbose'.  Multiple options passed in `LIBTOOLIZE_OPTIONS' must be
+separated with a space, comma or a colon.
+
+   By default, a warning is issued for unknown options found in
+`LIBTOOLIZE_OPTIONS' unless the first such option is `--no-warn'.
+Where `libtoolize' has always quit on receipt of an unknown option at
+the command line, this and all previous releases of `libtoolize' will
+continue unabated whatever the content of `LIBTOOLIZE_OPTIONS' (modulo
+some possible warning messages).
+
+     trick$ LIBTOOLIZE_OPTIONS=--no-warn,--quiet autoreconf --install
+
+   If `libtoolize' detects an explicit call to `AC_CONFIG_MACRO_DIR'
+(*note The Autoconf Manual: (autoconf)Input.) in your `configure.ac',
+it will put the Libtool macros in the specified directory.
+
+   In the future other Autotools will automatically check the contents
+of `AC_CONFIG_MACRO_DIR', but at the moment it is more portable to add
+the macro directory to `ACLOCAL_AMFLAGS' in `Makefile.am', which is
+where the tools currently look.  If `libtoolize' doesn't see
+`AC_CONFIG_MACRO_DIR', it too will honour the first `-I' argument in
+`ACLOCAL_AMFLAGS' when choosing a directory to store libtool
+configuration macros in.  It is perfectly sensible to use both
+`AC_CONFIG_MACRO_DIR' and `ACLOCAL_AMFLAGS', as long as they are kept
+in synchronisation.
+
+     ACLOCAL_AMFLAGS = -I m4
+
+   When you bootstrap your project with `aclocal', then you will need
+to explicitly pass the same macro directory with `aclocal''s `-I' flag:
+
+     trick$ aclocal -I m4
+
+   If `libtoolize' detects an explicit call to `AC_CONFIG_AUX_DIR'
+(*note The Autoconf Manual: (autoconf)Input.) in your `configure.ac', it
+will put the other support files in the specified directory.  Otherwise
+they too end up in the project root directory.
+
+   Unless `--no-warn' is passed, `libtoolize' displays hints for adding
+libtool support to your package, as well.

+5.5.2 Autoconf and `LTLIBOBJS'
+------------------------------
+
+People used to add code like the following to their `configure.ac':
+
+     LTLIBOBJS=`echo "$LIBOBJS" | sed 's/\.[^.]* /.lo /g;s/\.[^.]*$/.lo/'`
+     AC_SUBST([LTLIBOBJS])
+
+This is no longer required (since Autoconf 2.54), and doesn't take
+Automake's deansification support into account either, so doesn't work
+correctly even with ancient Autoconfs!
+
+   Provided you are using a recent (2.54 or better) incarnation of
+Autoconf, the call to `AC_OUTPUT' takes care of setting `LTLIBOBJS' up
+correctly, so you can simply delete such snippets from your
+`configure.ac' if you had them.

+
+5.6 Static-only libraries
+=========================
+
+When you are developing a package, it is often worthwhile to configure
+your package with the `--disable-shared' flag, or to override the
+defaults for `LT_INIT' by using the `disable-shared' option (*note The
+`LT_INIT' macro: LT_INIT.).  This prevents libtool from building shared
+libraries, which has several advantages:
+
+   * compilation is twice as fast, which can speed up your development
+     cycle,
+
+   * debugging is easier because you don't need to deal with any
+     complexities added by shared libraries, and
+
+   * you can see how libtool behaves on static-only platforms.
+
+   You may want to put a small note in your package `README' to let
+other developers know that `--disable-shared' can save them time.  The
+following example note is taken from the GIMP(1) distribution `README':
+
+     The GIMP uses GNU Libtool in order to build shared libraries on a
+     variety of systems.  While this is very nice for making usable
+     binaries, it can be a pain when trying to debug a program.  For that
+     reason, compilation of shared libraries can be turned off by
+     specifying the `--disable-shared' option to `configure'.

+6 Using libtool with other languages
+************************************
+
+Libtool was first implemented in order to add support for writing shared
+libraries in the C language.  However, over time, libtool is being
+integrated with other languages, so that programmers are free to reap
+the benefits of shared libraries in their favorite programming language.
+
+   This chapter describes how libtool interacts with other languages,
+and what special considerations you need to make if you do not use C.
+
+* Menu:

+
+
+File: libtool.info,  Node: C++ libraries,  Next: Tags,  Up: Other languages
+
+6.1 Writing libraries for C++
+=============================
+
+Creating libraries of C++ code should be a fairly straightforward
+process, because its object files differ from C ones in only three ways:
+
+  1. Because of name mangling, C++ libraries are only usable by the C++
+     compiler that created them.  This decision was made by the
+     designers of C++ in order to protect users from conflicting
+     implementations of features such as constructors, exception
+     handling, and RTTI.
+
+  2. On some systems, the C++ compiler must take special actions for the
+     dynamic linker to run dynamic (i.e., run-time) initializers.  This
+     means that we should not call `ld' directly to link such
+     libraries, and we should use the C++ compiler instead.
+
+  3. C++ compilers will link some Standard C++ library in by default,
+     but libtool does not know which are these libraries, so it cannot
+     even run the inter-library dependence analyzer to check how to
+     link it in.  Therefore, running `ld' to link a C++ program or
+     library is deemed to fail.
+
+   Because of these three issues, Libtool has been designed to always
+use the C++ compiler to compile and link C++ programs and libraries.  In
+some instances the `main()' function of a program must also be compiled
+with the C++ compiler for static C++ objects to be properly initialized.
+
+
+File: libtool.info,  Node: Tags,  Prev: C++ libraries,  Up: Other languages
+
+6.2 Tags
+========
+
+Libtool supports multiple languages through the use of tags.
+Technically a tag corresponds to a set of configuration variables
+associated with a language.  These variables tell `libtool' how it
+should create objects and libraries for each language.
+
+   Tags are defined at `configure'-time for each language activated in
+the package (see `LT_LANG' in *note LT_INIT::).  Here is the
+correspondence between language names and tags names.
+
+Language name      Tag name
+C                  CC
+C++                CXX
+Java               GCJ
+Fortran 77         F77
+Fortran            FC
+Go                 GO
+Windows Resource   RC
+
+   `libtool' tries to automatically infer which tag to use from the
+compiler command being used to compile or link.  If it can't infer a
+tag, then it defaults to the configuration for the `C' language.
+
+   The tag can also be specified using `libtool''s `--tag=TAG' option
+(*note Invoking libtool::).  It is a good idea to do so in `Makefile'
+rules, because that will allow users to substitute the compiler without
+relying on `libtool' inference heuristics.  When no tag is specified,
+`libtool' will default to `CC'; this tag always exists.
+
+   Finally, the set of tags available in a particular project can be
+retrieved by tracing for the `LT_SUPPORTED_TAG' macro (*note Trace
+interface::).

+
+7 Library interface versions
+****************************
+
+The most difficult issue introduced by shared libraries is that of
+creating and resolving runtime dependencies.  Dependencies on programs
+and libraries are often described in terms of a single name, such as
+`sed'.  So, one may say "libtool depends on sed," and that is good
+enough for most purposes.
+
+   However, when an interface changes regularly, we need to be more
+specific: "Gnus 5.1 requires Emacs 19.28 or above."  Here, the
+description of an interface consists of a name, and a "version number."
+
+   Even that sort of description is not accurate enough for some
+purposes.  What if Emacs 20 changes enough to break Gnus 5.1?
+
+   The same problem exists in shared libraries: we require a formal
+version system to describe the sorts of dependencies that programs have
+on shared libraries, so that the dynamic linker can guarantee that
+programs are linked only against libraries that provide the interface
+they require.
+

+
+7.1 What are library interfaces?
+================================
+
+Interfaces for libraries may be any of the following (and more):
+
+   * global variables: both names and types
+
+   * global functions: argument types and number, return types, and
+     function names
+
+   * standard input, standard output, standard error, and file formats
+
+   * sockets, pipes, and other inter-process communication protocol
+     formats
+
+   Note that static functions do not count as interfaces, because they
+are not directly available to the user of the library.
+
+
+File: libtool.info,  Node: Libtool versioning,  Next: Updating version info,  Prev: Interfaces,  Up: Versioning
+
+7.2 Libtool's versioning system
+===============================
+
+Libtool has its own formal versioning system.  It is not as flexible as
+some, but it is definitely the simplest of the more powerful versioning
+systems.
+
+   Think of a library as exporting several sets of interfaces,
+arbitrarily represented by integers.  When a program is linked against
+a library, it may use any subset of those interfaces.
+
+   Libtool's description of the interfaces that a program uses is
+simple: it encodes the least and the greatest interface numbers in the
+resulting binary (FIRST-INTERFACE, LAST-INTERFACE).
+
+   The dynamic linker is guaranteed that if a library supports _every_
+interface number between FIRST-INTERFACE and LAST-INTERFACE, then the
+program can be relinked against that library.
+
+   Note that this can cause problems because libtool's compatibility
+requirements are actually stricter than is necessary.
+
+   Say `libhello' supports interfaces 5, 16, 17, 18, and 19, and that
+libtool is used to link `test' against `libhello'.
+
+   Libtool encodes the numbers 5 and 19 in `test', and the dynamic
+linker will only link `test' against libraries that support _every_
+interface between 5 and 19.  So, the dynamic linker refuses to link
+`test' against `libhello'!
+
+   In order to eliminate this problem, libtool only allows libraries to
+declare consecutive interface numbers.  So, `libhello' can declare at
+most that it supports interfaces 16 through 19.  Then, the dynamic
+linker will link `test' against `libhello'.
+
+   So, libtool library versions are described by three integers:
+
+CURRENT
+     The most recent interface number that this library implements.
+
+REVISION
+     The implementation number of the CURRENT interface.
+
+AGE
+     The difference between the newest and oldest interfaces that this
+     library implements.  In other words, the library implements all the
+     interface numbers in the range from number `CURRENT - AGE' to
+     `CURRENT'.
+
+   If two libraries have identical CURRENT and AGE numbers, then the
+dynamic linker chooses the library with the greater REVISION number.
+
+
+File: libtool.info,  Node: Updating version info,  Next: Release numbers,  Prev: Libtool versioning,  Up: Versioning
+
+7.3 Updating library version information
+========================================
+
+If you want to use libtool's versioning system, then you must specify
+the version information to libtool using the `-version-info' flag
+during link mode (*note Link mode::).
+
+   This flag accepts an argument of the form
+`CURRENT[:REVISION[:AGE]]'.  So, passing `-version-info 3:12:1' sets
+CURRENT to 3, REVISION to 12, and AGE to 1.
+
+   If either REVISION or AGE are omitted, they default to 0.  Also note
+that AGE must be less than or equal to the CURRENT interface number.
+
+   Here are a set of rules to help you update your library version
+information:
+
+  1. Start with version information of `0:0:0' for each libtool library.
+
+  2. Update the version information only immediately before a public
+     release of your software.  More frequent updates are unnecessary,
+     and only guarantee that the current interface number gets larger
+     faster.
+
+  3. If the library source code has changed at all since the last
+     update, then increment REVISION (`C:R:A' becomes `C:r+1:A').
+
+  4. If any interfaces have been added, removed, or changed since the
+     last update, increment CURRENT, and set REVISION to 0.
+
+  5. If any interfaces have been added since the last public release,
+     then increment AGE.
+
+  6. If any interfaces have been removed or changed since the last
+     public release, then set AGE to 0.
+
+   *_Never_* try to set the interface numbers so that they correspond
+to the release number of your package.  This is an abuse that only
+fosters misunderstanding of the purpose of library versions.  Instead,
+use the `-release' flag (*note Release numbers::), but be warned that
+every release of your package will not be binary compatible with any
+other release.
+
+   The following explanation may help to understand the above rules a
+bit better: consider that there are three possible kinds of reactions
+from users of your library to changes in a shared library:
+
+  1. Programs using the previous version may use the new version as
+     drop-in replacement, and programs using the new version can also
+     work with the previous one.  In other words, no recompiling nor
+     relinking is needed.  In this case, bump REVISION only, don't touch
+     CURRENT nor AGE.
+
+  2. Programs using the previous version may use the new version as
+     drop-in replacement, but programs using the new version may use
+     APIs not present in the previous one.  In other words, a program
+     linking against the new version may fail with "unresolved symbols"
+     if linking against the old version at runtime: set REVISION to 0,
+     bump CURRENT and AGE.
+
+  3. Programs may need to be changed, recompiled, relinked in order to
+     use the new version.  Bump CURRENT, set REVISION and AGE to 0.
+
+In the above description, _programs_ using the library in question may
+also be replaced by other libraries using it.

+
+7.4 Managing release information
+================================
+
+Often, people want to encode the name of the package release into the
+shared library so that it is obvious to the user which package their
+programs are linked against.  This convention is used especially on
+GNU/Linux:
+
+     trick$ ls /usr/lib/libbfd*
+     /usr/lib/libbfd.a           /usr/lib/libbfd.so.2.7.0.2
+     /usr/lib/libbfd.so
+     trick$
+
+   On `trick', `/usr/lib/libbfd.so' is a symbolic link to
+`libbfd.so.2.7.0.2', which was distributed as a part of
+`binutils-2.7.0.2'.
+
+   Unfortunately, this convention conflicts directly with libtool's
+idea of library interface versions, because the library interface
+rarely changes at the same time that the release number does, and the
+library suffix is never the same across all platforms.
+
+   So, in order to accommodate both views, you can use the `-release'
+flag in order to set release information for libraries for which you do
+not want to use `-version-info'.  For the `libbfd' example, the next
+release that uses libtool should be built with `-release 2.9.0', which
+will produce the following files on GNU/Linux:
+
+     trick$ ls /usr/lib/libbfd*
+     /usr/lib/libbfd-2.9.0.so     /usr/lib/libbfd.a
+     /usr/lib/libbfd.so
+     trick$
+
+   In this case, `/usr/lib/libbfd.so' is a symbolic link to
+`libbfd-2.9.0.so'.  This makes it obvious that the user is dealing with
+`binutils-2.9.0', without compromising libtool's idea of interface
+versions.
+
+   Note that this option causes a modification of the library name, so
+do not use it unless you want to break binary compatibility with any
+past library releases.  In general, you should only use `-release' for
+package-internal libraries or for ones whose interfaces change very
+frequently.

+8 Tips for interface design
+***************************
+
+Writing a good library interface takes a lot of practice and thorough
+understanding of the problem that the library is intended to solve.
+
+   If you design a good interface, it won't have to change often, you
+won't have to keep updating documentation, and users won't have to keep
+relearning how to use the library.
+
+   Here is a brief list of tips for library interface design that may
+help you in your exploits:
+
+Plan ahead
+     Try to make every interface truly minimal, so that you won't need
+     to delete entry points very often.
+
+Avoid interface changes
+     Some people love redesigning and changing entry points just for
+     the heck of it (note: _renaming_ a function is considered changing
+     an entry point).  Don't be one of those people.  If you must
+     redesign an interface, then try to leave compatibility functions
+     behind so that users don't need to rewrite their existing code.
+
+Use opaque data types
+     The fewer data type definitions a library user has access to, the
+     better.  If possible, design your functions to accept a generic
+     pointer (that you can cast to an internal data type), and provide
+     access functions rather than allowing the library user to directly
+     manipulate the data.  That way, you have the freedom to change the
+     data structures without changing the interface.
+
+     This is essentially the same thing as using abstract data types and
+     inheritance in an object-oriented system.
+
+Use header files
+     If you are careful to document each of your library's global
+     functions and variables in header files, and include them in your
+     library source files, then the compiler will let you know if you
+     make any interface changes by accident (*note C header files::).
+
+Use the `static' keyword (or equivalent) whenever possible
+     The fewer global functions your library has, the more flexibility
+     you'll have in changing them.  Static functions and variables may
+     change forms as often as you like... your users cannot access
+     them, so they aren't interface changes.
+
+Be careful with array dimensions
+     The number of elements in a global array is part of an interface,
+     even if the header just declares `extern int foo[];'.  This is
+     because on i386 and some other SVR4/ELF systems, when an
+     application references data in a shared library the size of that
+     data (whatever its type) is included in the application
+     executable.  If you might want to change the size of an array or
+     string then provide a pointer not the actual array.

+
+8.1 Writing C header files
+==========================
+
+Writing portable C header files can be difficult, since they may be read
+by different types of compilers:
+
+C++ compilers
+     C++ compilers require that functions be declared with full
+     prototypes, since C++ is more strongly typed than C.  C functions
+     and variables also need to be declared with the `extern "C"'
+     directive, so that the names aren't mangled.  *Note C++
+     libraries::, for other issues relevant to using C++ with libtool.
+
+ANSI C compilers
+     ANSI C compilers are not as strict as C++ compilers, but functions
+     should be prototyped to avoid unnecessary warnings when the header
+     file is `#include'd.
+
+non-ANSI C compilers
+     Non-ANSI compilers will report errors if functions are prototyped.
+
+   These complications mean that your library interface headers must use
+some C preprocessor magic in order to be usable by each of the above
+compilers.
+
+   `foo.h' in the `tests/demo' subdirectory of the libtool distribution
+serves as an example for how to write a header file that can be safely
+installed in a system directory.
+
+   Here are the relevant portions of that file:
+
+     /* BEGIN_C_DECLS should be used at the beginning of your declarations,
+        so that C++ compilers don't mangle their names.  Use END_C_DECLS at
+        the end of C declarations. */
+     #undef BEGIN_C_DECLS
+     #undef END_C_DECLS
+     #ifdef __cplusplus
+     # define BEGIN_C_DECLS extern "C" {
+     # define END_C_DECLS }
+     #else
+     # define BEGIN_C_DECLS /* empty */
+     # define END_C_DECLS /* empty */
+     #endif
+
+     /* PARAMS is a macro used to wrap function prototypes, so that
+        compilers that don't understand ANSI C prototypes still work,
+        and ANSI C compilers can issue warnings about type mismatches. */
+     #undef PARAMS
+     #if defined (__STDC__) || defined (_AIX) \
+             || (defined (__mips) && defined (_SYSTYPE_SVR4)) \
+             || defined(WIN32) || defined(__cplusplus)
+     # define PARAMS(protos) protos
+     #else
+     # define PARAMS(protos) ()
+     #endif
+
+   These macros are used in `foo.h' as follows:
+
+     #ifndef FOO_H
+     #define FOO_H 1
+
+     /* The above macro definitions. */
+     #include "..."
+
+     BEGIN_C_DECLS
+
+     int foo PARAMS((void));
+     int hello PARAMS((void));
+
+     END_C_DECLS
+
+     #endif /* !FOO_H */
+
+   Note that the `#ifndef FOO_H' prevents the body of `foo.h' from
+being read more than once in a given compilation.
+
+   Also the only thing that must go outside the
+`BEGIN_C_DECLS'/`END_C_DECLS' pair are `#include' lines.  Strictly
+speaking it is only C symbol names that need to be protected, but your
+header files will be more maintainable if you have a single pair of
+these macros around the majority of the header contents.
+
+   You should use these definitions of `PARAMS', `BEGIN_C_DECLS', and
+`END_C_DECLS' into your own headers.  Then, you may use them to create
+header files that are valid for C++, ANSI, and non-ANSI compilers(1).
+
+   Do not be naive about writing portable code.  Following the tips
+given above will help you miss the most obvious problems, but there are
+definitely other subtle portability issues.  You may need to cope with
+some of the following issues:
+
+   * Pre-ANSI compilers do not always support the `void *' generic
+     pointer type, and so need to use `char *' in its place.
+
+   * The `const', `inline' and `signed' keywords are not supported by
+     some compilers, especially pre-ANSI compilers.
+
+   * The `long double' type is not supported by many compilers.
+
+   ---------- Footnotes ----------
+
+   (1) We used to recommend `__P', `__BEGIN_DECLS' and `__END_DECLS'.
+This was bad advice since symbols (even preprocessor macro names) that
+begin with an underscore are reserved for the use of the compiler.

+9 Inter-library dependencies
+****************************
+
+By definition, every shared library system provides a way for
+executables to depend on libraries, so that symbol resolution is
+deferred until runtime.
+
+   An "inter-library dependency" is one in which a library depends on
+other libraries.  For example, if the libtool library `libhello' uses
+the `cos' function, then it has an inter-library dependency on `libm',
+the math library that implements `cos'.
+
+   Some shared library systems provide this feature in an
+internally-consistent way: these systems allow chains of dependencies of
+potentially infinite length.
+
+   However, most shared library systems are restricted in that they only
+allow a single level of dependencies.  In these systems, programs may
+depend on shared libraries, but shared libraries may not depend on other
+shared libraries.
+
+   In any event, libtool provides a simple mechanism for you to declare
+inter-library dependencies: for every library `libNAME' that your own
+library depends on, simply add a corresponding `-lNAME' option to the
+link line when you create your library.  To make an example of our
+`libhello' that depends on `libm':
+
+     burger$ libtool --mode=link gcc -g -O -o libhello.la foo.lo hello.lo \
+                     -rpath /usr/local/lib -lm
+     burger$
+
+   When you link a program against `libhello', you don't need to
+specify the same `-l' options again: libtool will do that for you, in
+order to guarantee that all the required libraries are found.  This
+restriction is only necessary to preserve compatibility with static
+library systems and simple dynamic library systems.
+
+   Some platforms, such as Windows, do not even allow you this
+flexibility.  In order to build a shared library, it must be entirely
+self-contained or it must have dependencies known at link time (that is,
+have references only to symbols that are found in the `.lo' files or
+the specified `-l' libraries), and you need to specify the
+`-no-undefined' flag.  By default, libtool builds only static libraries
+on these kinds of platforms.
+
+   The simple-minded inter-library dependency tracking code of libtool
+releases prior to 1.2 was disabled because it was not clear when it was
+possible to link one library with another, and complex failures would
+occur.  A more complex implementation of this concept was re-introduced
+before release 1.3, but it has not been ported to all platforms that
+libtool supports.  The default, conservative behavior is to avoid
+linking one library with another, introducing their inter-dependencies
+only when a program is linked with them.

+10 Dlopened modules
+*******************
+
+It can sometimes be confusing to discuss "dynamic linking", because the
+term is used to refer to two different concepts:
+
+  1. Compiling and linking a program against a shared library, which is
+     resolved automatically at run time by the dynamic linker.  In this
+     process, dynamic linking is transparent to the application.
+
+  2. The application calling functions such as `dlopen' that load
+     arbitrary, user-specified modules at runtime.  This type of dynamic
+     linking is explicitly controlled by the application.
+
+   To mitigate confusion, this manual refers to the second type of
+dynamic linking as "dlopening" a module.
+
+   The main benefit to dlopening object modules is the ability to access
+compiled object code to extend your program, rather than using an
+interpreted language.  In fact, dlopen calls are frequently used in
+language interpreters to provide an efficient way to extend the
+language.
+
+   Libtool provides support for dlopened modules.  However, you should
+indicate that your package is willing to use such support, by using the
+`LT_INIT' option `dlopen' in `configure.ac'.  If this option is not
+given, libtool will assume no dlopening mechanism is available, and
+will try to simulate it.
+
+   This chapter discusses how you as a dlopen application developer
+might use libtool to generate dlopen-accessible modules.

+
+10.1 Building modules to dlopen
+===============================
+
+On some operating systems, a program symbol must be specially declared
+in order to be dynamically resolved with the `dlsym' (or equivalent)
+function.  Libtool provides the `-export-dynamic' and `-module' link
+flags (*note Link mode::), for you to make that declaration.  You need
+to use these flags if you are linking an application program that
+dlopens other modules or a libtool library that will also be dlopened.
+
+   For example, if we wanted to build a shared library, `hello', that
+would later be dlopened by an application, we would add `-module' to
+the other link flags:
+
+     burger$ libtool --mode=link gcc -module -o hello.la foo.lo \
+                     hello.lo -rpath /usr/local/lib -lm
+     burger$
+
+   If symbols from your _executable_ are needed to satisfy unresolved
+references in a library you want to dlopen you will have to use the flag
+`-export-dynamic'.  You should use `-export-dynamic' while linking the
+executable that calls dlopen:
+
+     burger$ libtool --mode=link gcc -export-dynamic -o helldl main.o
+     burger$
+

+
+10.2 Dlpreopening
+=================
+
+Libtool provides special support for dlopening libtool object and
+libtool library files, so that their symbols can be resolved _even on
+platforms without any `dlopen' and `dlsym' functions_.
+
+   Consider the following alternative ways of loading code into your
+program, in order of increasing "laziness":
+
+  1. Linking against object files that become part of the program
+     executable, whether or not they are referenced.  If an object file
+     cannot be found, then the compile time linker refuses to create
+     the executable.
+
+  2. Declaring a static library to the linker, so that it is searched
+     at link time in order to satisfy any undefined references in the
+     above object files.  If the static library cannot be found, then
+     the compile time linker refuses to create the executable.
+
+  3. Declaring a shared library to the runtime linker, so that it is
+     searched at runtime in order to satisfy any undefined references
+     in the above files.  If the shared library cannot be found, then
+     the dynamic linker aborts the program before it runs.
+
+  4. Dlopening a module, so that the application can resolve its own,
+     dynamically-computed references.  If there is an error opening the
+     module, or the module is not found, then the application can
+     recover without crashing.
+
+   Libtool emulates `-dlopen' on static platforms by linking objects
+into the program at compile time, and creating data structures that
+represent the program's symbol table.  In order to use this feature,
+you must declare the objects you want your application to dlopen by
+using the `-dlopen' or `-dlpreopen' flags when you link your program
+(*note Link mode::).
+
+ -- Data Type: lt_dlsymlist typedef struct { const char *NAME;
+          void *ADDRESS; } lt_dlsymlist
+     The NAME attribute is a null-terminated character string of the
+     symbol name, such as `"fprintf"'.  The ADDRESS attribute is a
+     generic pointer to the appropriate object, such as `&fprintf'.
+
+ -- Variable: const lt_dlsymlist  lt_preloaded_symbols[]
+     An array of `lt_dlsymlist' structures, representing all the
+     preloaded symbols linked into the program proper.  For each module
+     `-dlpreopen'ed by the Libtool linked program there is an element
+     with the NAME of the module and an ADDRESS of `0', followed by all
+     symbols exported from this file.  For the executable itself the
+     special name `@PROGRAM@' is used.  The last element of all has a
+     NAME and ADDRESS of `0'.
+
+     To facilitate inclusion of symbol lists into libraries,
+     `lt_preloaded_symbols' is `#define'd to a suitably unique name in
+     `ltdl.h'.
+
+     This variable may not be declared `const' on some systems due to
+     relocation issues.
+
+   Some compilers may allow identifiers that are not valid in ANSI C,
+such as dollar signs.  Libtool only recognizes valid ANSI C symbols (an
+initial ASCII letter or underscore, followed by zero or more ASCII
+letters, digits, and underscores), so non-ANSI symbols will not appear
+in `lt_preloaded_symbols'.
+
+ -- Function: int lt_dlpreload (const lt_dlsymlist *PRELOADED)
+     Register the list of preloaded modules PRELOADED.  If PRELOADED is
+     `NULL', then all previously registered symbol lists, except the
+     list set by `lt_dlpreload_default', are deleted.  Return 0 on
+     success.
+
+ -- Function: int lt_dlpreload_default (const lt_dlsymlist *PRELOADED)
+     Set the default list of preloaded modules to PRELOADED, which
+     won't be deleted by `lt_dlpreload'.  Note that this function does
+     _not_ require libltdl to be initialized using `lt_dlinit' and can
+     be used in the program to register the default preloaded modules.
+     Instead of calling this function directly, most programs will use
+     the macro `LTDL_SET_PRELOADED_SYMBOLS'.
+
+     Return 0 on success.
+
+ -- Macro: LTDL_SET_PRELOADED_SYMBOLS
+     Set the default list of preloaded symbols.  Should be used in your
+     program to initialize libltdl's list of preloaded modules.
+
+          #include <ltdl.h>
+
+          int main() {
+            /* ... */
+            LTDL_SET_PRELOADED_SYMBOLS();
+            /* ... */
+          }
+
+ -- Function Type: int lt_dlpreload_callback_func (lt_dlhandle HANDLE)
+     Functions of this type can be passed to `lt_dlpreload_open', which
+     in turn will call back into a function thus passed for each
+     preloaded module that it opens.
+
+ -- Function: int lt_dlpreload_open (const char *ORIGINATOR,
+          lt_dlpreload_callback_func *FUNC)
+     Load all of the preloaded modules for ORIGINATOR.  For every
+     module opened in this way, call FUNC.
+
+     To open all of the modules preloaded into `libhell.la' (presumably
+     from within the `libhell.a' initialisation code):
+
+          #define preloaded_symbols lt_libhell_LTX_preloaded_symbols
+
+          static int hell_preload_callback (lt_dlhandle handle);
+
+          int
+          hell_init (void)
+          {
+            ...
+            if (lt_dlpreload (&preloaded_symbols) == 0)
+              {
+                lt_dlpreload_open ("libhell", preload_callback);
+              }
+            ...
+          }
+
+     Note that to prevent clashes between multiple preloaded modules,
+     the preloaded symbols are accessed via a mangled symbol name: to
+     get the symbols preloaded into `libhell', you must prefix
+     `preloaded_symbols' with `lt_'; the originator name, `libhell' in
+     this case; and `_LTX_'.  That is,
+     `lt_libhell_LTX_preloaded_symbols' here.

+
+10.3 Linking with dlopened modules
+==================================
+
+When, say, an interpreter application uses dlopened modules to extend
+the list of methods it provides, an obvious abstraction for the
+maintainers of the interpreter is to have all methods (including the
+built in ones supplied with the interpreter) accessed through dlopen.
+For one thing, the dlopening functionality will be tested even during
+routine invocations.  For another, only one subsystem has to be written
+for getting methods into the interpreter.
+
+   The downside of this abstraction is, of course, that environments
+that provide only static linkage can't even load the intrinsic
+interpreter methods.  Not so!  We can statically link those methods by
+*dlpreopening* them.
+
+   Unfortunately, since platforms such as AIX and cygwin require that
+all library symbols must be resolved at compile time, the interpreter
+maintainers will need to provide a library to both its own dlpreopened
+modules, and third-party modules loaded by dlopen.  In itself, that is
+not so bad, except that the interpreter too must provide those same
+symbols otherwise it will be impossible to resolve all the symbols
+required by the modules as they are loaded.  Things are even worse if
+the code that loads the modules for the interpreter is itself in a
+library - and that is usually the case for any non-trivial application.
+Modern platforms take care of this by automatically loading all of a
+module's dependency libraries as the module is loaded (libltdl can do
+this even on platforms that can't do it by themselves).  In the end,
+this leads to problems with duplicated symbols and prevents modules
+from loading, and prevents the application from compiling when modules
+are preloaded.

+                        `------------------'
+
+   Libtool has the concept of "weak library interfaces" to circumvent
+this problem.  Recall that the code that dlopens method-provider
+modules for the interpreter application resides in a library: All of
+the modules and the dlopener library itself should be linked against
+the common library that resolves the module symbols at compile time.
+To guard against duplicate symbol definitions, and for dlpreopened
+modules to work at all in this scenario, the dlopener library must
+declare that it provides a weak library interface to the common symbols
+in the library it shares with the modules.  That way, when `libtool'
+links the *Module Loader* library with some *Dlpreopened Modules* that
+were in turn linked against the *Module Interface Library*, it knows
+that the *Module Loader* provides an already loaded *Module Interface
+Library* to resolve symbols for the *Dlpreopened Modules*, and doesn't
+ask the compiler driver to link an identical *Module Interface Library*
+dependency library too.
+
+   In conjunction with Automake, the `Makefile.am' for the *Module
+Loader* might look like this:
+
+     lib_LTLIBRARIES = libinterface.la libloader.la
+
+     libinterface_la_SOURCES = interface.c interface.h
+     libinterface_la_LDFLAGS = -version-info 3:2:1
+
+     libloader_la_SOURCES    = loader.c
+     libloader_la_LDFLAGS    = -weak libinterface.la \
+                               -version-info 3:2:1 \
+                               -dlpreopen ../modules/intrinsics.la
+     libloader_la_LIBADD     = $(libinterface_la_OBJECTS)
+
+   And the `Makefile.am' for the `intrinsics.la' module in a sibling
+`modules' directory might look like this:
+
+     AM_CPPFLAGS             = -I$(srcdir)/../libloader
+     AM_LDFLAGS              = -no-undefined -module -avoid-version \
+                               -export-dynamic
+
+     noinst_LTLIBRARIES      = intrinsics.la
+
+     intrinsics_la_LIBADD    = ../libloader/libinterface.la
+
+     ../libloader/libinterface.la:
+             cd ../libloader && $(MAKE) $(AM_MAKEFLAGS) libinterface.la
+
+   For a more complex example, see the sources of `libltdl' in the
+Libtool distribution, which is built with the help of the `-weak'
+option.

+
+10.4 Finding the correct name to dlopen
+=======================================
+
+After a library has been linked with `-module', it can be dlopened.
+Unfortunately, because of the variation in library names, your package
+needs to determine the correct file to dlopen.
+
+   The most straightforward and flexible implementation is to determine
+the name at runtime, by finding the installed `.la' file, and searching
+it for the following lines:
+
+     # The name that we can `dlopen'.
+     dlname='DLNAME'
+
+   If DLNAME is empty, then the library cannot be dlopened.  Otherwise,
+it gives the dlname of the library.  So, if the library was installed
+as `/usr/local/lib/libhello.la', and the DLNAME was `libhello.so.3',
+then `/usr/local/lib/libhello.so.3' should be dlopened.
+
+   If your program uses this approach, then it should search the
+directories listed in the `LD_LIBRARY_PATH'(1) environment variable, as
+well as the directory where libraries will eventually be installed.
+Searching this variable (or equivalent) will guarantee that your
+program can find its dlopened modules, even before installation,
+provided you have linked them using libtool.

+10.5 Unresolved dlopen issues
+=============================
+
+The following problems are not solved by using libtool's dlopen support:
+
+   * Dlopen functions are generally only available on shared library
+     platforms.  If you want your package to be portable to static
+     platforms, you have to use either libltdl (*note Using libltdl::)
+     or develop your own alternatives to dlopening dynamic code.  Most
+     reasonable solutions involve writing wrapper functions for the
+     `dlopen' family, which do package-specific tricks when dlopening
+     is unsupported or not available on a given platform.
+
+   * There are major differences in implementations of the `dlopen'
+     family of functions.  Some platforms do not even use the same
+     function names (notably HP-UX, with its `shl_load' family).
+
+   * The application developer must write a custom search function in
+     order to discover the correct module filename to supply to
+     `dlopen'.

+11 Using libltdl
+****************
+
+Libtool provides a small library, called `libltdl', that aims at hiding
+the various difficulties of dlopening libraries from programmers.  It
+consists of a few headers and small C source files that can be
+distributed with applications that need dlopening functionality.  On
+some platforms, whose dynamic linkers are too limited for a simple
+implementation of `libltdl' services, it requires GNU DLD, or it will
+only emulate dynamic linking with libtool's dlpreopening mechanism.
+
+libltdl supports currently the following dynamic linking mechanisms:
+
+   * `dlopen' (POSIX compliant systems, GNU/Linux, etc.)
+
+   * `shl_load' (HP-UX)
+
+   * `LoadLibrary' (Win16 and Win32)
+
+   * `load_add_on' (BeOS)
+
+   * `NSAddImage' or `NSLinkModule' (Darwin and Mac OS X)
+
+   * GNU DLD (emulates dynamic linking for static libraries)
+
+   * libtool's dlpreopen (see *note Dlpreopening::)

+
+11.1 How to use libltdl in your programs
+========================================
+
+The libltdl API is similar to the POSIX dlopen interface, which is very
+simple but powerful.
+
+To use libltdl in your program you have to include the header file
+`ltdl.h':
+
+     #include <ltdl.h>
+
+The early releases of libltdl used some symbols that violated the POSIX
+namespace conventions.  These symbols are now deprecated, and have been
+replaced by those described here.  If you have code that relies on the
+old deprecated symbol names, defining `LT_NON_POSIX_NAMESPACE' before
+you include `ltdl.h' provides conversion macros.  Whichever set of
+symbols you use, the new API is not binary compatible with the last, so
+you will need to recompile your application in order to use this
+version of libltdl.
+
+Note that libltdl is not well tested in a multithreaded environment,
+though the intention is that it should work (*note Using libltdl in a
+multi threaded environment: Thread Safety in libltdl.).  It was
+reported that GNU/Linux's glibc 2.0's `dlopen' with `RTLD_LAZY' (which
+libltdl uses by default) is not thread-safe, but this problem is
+supposed to be fixed in glibc 2.1.  On the other hand, `RTLD_NOW' was
+reported to introduce problems in multi-threaded applications on
+FreeBSD.  Working around these problems is left as an exercise for the
+reader; contributions are certainly welcome.
+
+The following macros are defined by including `ltdl.h':
+
+ -- Macro: LT_PATHSEP_CHAR
+     `LT_PATHSEP_CHAR' is the system-dependent path separator, that is,
+     `;' on Windows and `:' everywhere else.
+
+ -- Macro: LT_DIRSEP_CHAR
+     If `LT_DIRSEP_CHAR' is defined, it can be used as directory
+     separator in addition to `/'.  On Windows, this contains `\'.
+
+The following types are defined in `ltdl.h':
+
+ -- Type: lt_dlhandle
+     `lt_dlhandle' is a module "handle".  Every lt_dlopened module has
+     a handle associated with it.
+
+ -- Type: lt_dladvise
+     `lt_dladvise' is used to control optional module loading modes.
+     If it is not used, the default mode of the underlying system module
+     loader is used.
+
+ -- Type: lt_dlsymlist
+     `lt_dlsymlist' is a symbol list for dlpreopened modules.  This
+     structure is described in *note Dlpreopening::.
+
+libltdl provides the following functions:
+
+ -- Function: int lt_dlinit (void)
+     Initialize libltdl.  This function must be called before using
+     libltdl and may be called several times.  Return 0 on success,
+     otherwise the number of errors.
+
+ -- Function: int lt_dlexit (void)
+     Shut down libltdl and close all modules.  This function will only
+     then shut down libltdl when it was called as many times as
+     `lt_dlinit' has been successfully called.  Return 0 on success,
+     otherwise the number of errors.
+
+ -- Function: lt_dlhandle lt_dlopen (const char *FILENAME)
+     Open the module with the file name FILENAME and return a handle
+     for it.  `lt_dlopen' is able to open libtool dynamic modules,
+     preloaded static modules, the program itself and native dynamic
+     modules(1).
+
+     Unresolved symbols in the module are resolved using its dependency
+     libraries and previously dlopened modules.  If the executable using
+     this module was linked with the `-export-dynamic' flag, then the
+     global symbols in the executable will also be used to resolve
+     references in the module.
+
+     If FILENAME is `NULL' and the program was linked with
+     `-export-dynamic' or `-dlopen self', `lt_dlopen' will return a
+     handle for the program itself, which can be used to access its
+     symbols.
+
+     If libltdl cannot find the library and the file name FILENAME does
+     not have a directory component it will additionally look in the
+     following search paths for the module (in the following order):
+
+       1. user-defined search path: This search path can be changed by
+          the program using the functions `lt_dlsetsearchpath',
+          `lt_dladdsearchdir' and `lt_dlinsertsearchdir'.
+
+       2. libltdl's search path: This search path is the value of the
+          environment variable `LTDL_LIBRARY_PATH'.
+
+       3. system library search path: The system dependent library
+          search path (e.g. on GNU/Linux it is `LD_LIBRARY_PATH').
+
+     Each search path must be a list of absolute directories separated
+     by `LT_PATHSEP_CHAR', for example, `"/usr/lib/mypkg:/lib/foo"'.
+     The directory names may not contain the path separator.
+
+     If the same module is loaded several times, the same handle is
+     returned.  If `lt_dlopen' fails for any reason, it returns `NULL'.
+
+ -- Function: lt_dlhandle lt_dlopenext (const char *FILENAME)
+     The same as `lt_dlopen', except that it tries to append different
+     file name extensions to the file name.  If the file with the file
+     name FILENAME cannot be found libltdl tries to append the
+     following extensions:
+
+       1. the libtool archive extension `.la'
+
+       2. the extension used for native dynamically loadable modules on
+          the host platform, e.g., `.so', `.sl', etc.
+
+     This lookup strategy was designed to allow programs that don't
+     have knowledge about native dynamic libraries naming conventions
+     to be able to `dlopen' such libraries as well as libtool modules
+     transparently.
+
+ -- Function: lt_dlhandle lt_dlopenadvise (const char *FILENAME,
+          lt_dladvise ADVISE)
+     The same as `lt_dlopen', except that it also requires an additional
+     argument which may contain additional hints to the underlying
+     system module loader.  The ADVISE parameter is opaque and can only
+     be accessed with the functions documented below.
+
+     Note that this function does not change the content of ADVISE, so
+     unlike the other calls in this API takes a direct `lt_dladvise'
+     type, and not a pointer to the same.
+
+ -- Function: int lt_dladvise_init (lt_dladvise *ADVISE)
+     The ADVISE parameter can be used to pass hints to the module
+     loader when using `lt_dlopenadvise' to perform the loading.  The
+     ADVISE parameter needs to be initialised by this function before
+     it can be used.  Any memory used by ADVISE needs to be recycled
+     with `lt_dladvise_destroy' when it is no longer needed.
+
+     On failure, `lt_dladvise_init' returns non-zero and sets an error
+     message that can be retrieved with `lt_dlerror'.
+
+ -- Function: int lt_dladvise_destroy (lt_dladvise *ADVISE)
+     Recycle the memory used by ADVISE.  For an example, see the
+     documentation for `lt_dladvise_ext'.
+
+     On failure, `lt_dladvise_destroy' returns non-zero and sets an
+     error message that can be retrieved with `lt_dlerror'.
+
+ -- Function: int lt_dladvise_ext (lt_dladvise *ADVISE)
+     Set the `ext' hint on ADVISE.  Passing an ADVISE parameter to
+     `lt_dlopenadvise' with this hint set causes it to try to append
+     different file name extensions like `lt_dlopenext'.
+
+     The following example is equivalent to calling `lt_dlopenext
+     (filename)':
+
+          lt_dlhandle
+          my_dlopenext (const char *filename)
+          {
+            lt_dlhandle handle = 0;
+            lt_dladvise advise;
+
+            if (!lt_dladvise_init (&advise) && !lt_dladvise_ext (&advise))
+              handle = lt_dlopenadvise (filename, advise);
+
+            lt_dladvise_destroy (&advise);
+
+            return handle;
+          }
+
+     On failure, `lt_dladvise_ext' returns non-zero and sets an error
+     message that can be retrieved with `lt_dlerror'.
+
+ -- Function: int lt_dladvise_global (lt_dladvise *ADVISE)
+     Set the `symglobal' hint on ADVISE.  Passing an ADVISE parameter
+     to `lt_dlopenadvise' with this hint set causes it to try to make
+     the loaded module's symbols globally available for resolving
+     unresolved symbols in subsequently loaded modules.
+
+     If neither the `symglobal' nor the `symlocal' hints are set, or if
+     a module is loaded without using the `lt_dlopenadvise' call in any
+     case, then the visibility of the module's symbols will be as per
+     the default for the underlying module loader and OS.  Even if a
+     suitable hint is passed, not all loaders are able to act upon it in
+     which case `lt_dlgetinfo' will reveal whether the hint was actually
+     followed.
+
+     On failure, `lt_dladvise_global' returns non-zero and sets an error
+     message that can be retrieved with `lt_dlerror'.
+
+ -- Function: int lt_dladvise_local (lt_dladvise *ADVISE)
+     Set the `symlocal' hint on ADVISE.  Passing an ADVISE parameter to
+     `lt_dlopenadvise' with this hint set causes it to try to keep the
+     loaded module's symbols hidden so that they are not visible to
+     subsequently loaded modules.
+
+     If neither the `symglobal' nor the `symlocal' hints are set, or if
+     a module is loaded without using the `lt_dlopenadvise' call in any
+     case, then the visibility of the module's symbols will be as per
+     the default for the underlying module loader and OS.  Even if a
+     suitable hint is passed, not all loaders are able to act upon it in
+     which case `lt_dlgetinfo' will reveal whether the hint was actually
+     followed.
+
+     On failure, `lt_dladvise_local' returns non-zero and sets an error
+     message that can be retrieved with `lt_dlerror'.
+
+ -- Function: int lt_dladvise_resident (lt_dladvise *ADVISE)
+     Set the `resident' hint on ADVISE.  Passing an ADVISE parameter to
+     `lt_dlopenadvise' with this hint set causes it to try to make the
+     loaded module resident in memory, so that it cannot be unloaded
+     with a later call to `lt_dlclose'.
+
+     On failure, `lt_dladvise_resident' returns non-zero and sets an
+     error message that can be retrieved with `lt_dlerror'.
+
+ -- Function: int lt_dladvise_preload (lt_dladvise *ADVISE)
+     Set the `preload' hint on ADVISE.  Passing an ADVISE parameter to
+     `lt_dlopenadvise' with this hint set causes it to load only
+     preloaded modules, so that if a suitable preloaded module is not
+     found, `lt_dlopenadvise' will return `NULL'.
+
+ -- Function: int lt_dlclose (lt_dlhandle HANDLE)
+     Decrement the reference count on the module HANDLE.  If it drops
+     to zero and no other module depends on this module, then the
+     module is unloaded.  Return 0 on success.
+
+ -- Function: void * lt_dlsym (lt_dlhandle HANDLE, const char *NAME)
+     Return the address in the module HANDLE, where the symbol given by
+     the null-terminated string NAME is loaded.  If the symbol cannot
+     be found, `NULL' is returned.
+
+ -- Function: const char * lt_dlerror (void)
+     Return a human readable string describing the most recent error
+     that occurred from any of libltdl's functions.  Return `NULL' if
+     no errors have occurred since initialization or since it was last
+     called.
+
+ -- Function: int lt_dladdsearchdir (const char *SEARCH_DIR)
+     Append the search directory SEARCH_DIR to the current user-defined
+     library search path.  Return 0 on success.
+
+ -- Function: int lt_dlinsertsearchdir (const char *BEFORE,
+          const char *SEARCH_DIR)
+     Insert the search directory SEARCH_DIR into the user-defined
+     library search path, immediately before the element starting at
+     address BEFORE.  If BEFORE is `NULL', then SEARCH_DIR is appending
+     as if `lt_dladdsearchdir' had been called.  Return 0 on success.
+
+ -- Function: int lt_dlsetsearchpath (const char *SEARCH_PATH)
+     Replace the current user-defined library search path with
+     SEARCH_PATH, which must be a list of absolute directories separated
+     by `LT_PATHSEP_CHAR'.  Return 0 on success.
+
+ -- Function: const char * lt_dlgetsearchpath (void)
+     Return the current user-defined library search path.
+
+ -- Function: int lt_dlforeachfile (const char *SEARCH_PATH,
+          int (*FUNC) (const char *FILENAME, void * DATA), void * DATA)
+     In some applications you may not want to load individual modules
+     with known names, but rather find all of the modules in a set of
+     directories and load them all during initialisation.  With this
+     function you can have libltdl scan the `LT_PATHSEP_CHAR'-delimited
+     directory list in SEARCH_PATH for candidates, and pass them, along
+     with DATA to your own callback function, FUNC.  If SEARCH_PATH is
+     `NULL', then search all of the standard locations that `lt_dlopen'
+     would examine.  This function will continue to make calls to FUNC
+     for each file that it discovers in SEARCH_PATH until one of these
+     calls returns non-zero, or until the files are exhausted.
+     `lt_dlforeachfile' returns the value returned by the last call
+     made to FUNC.
+
+     For example you could define FUNC to build an ordered "argv"-like
+     vector of files using DATA to hold the address of the start of the
+     vector.
+
+ -- Function: int lt_dlmakeresident (lt_dlhandle HANDLE)
+     Mark a module so that it cannot be `lt_dlclose'd.  This can be
+     useful if a module implements some core functionality in your
+     project that would cause your code to crash if removed.  Return 0
+     on success.
+
+     If you use `lt_dlopen (NULL)' to get a HANDLE for the running
+     binary, that handle will always be marked as resident, and
+     consequently cannot be successfully `lt_dlclose'd.
+
+ -- Function: int lt_dlisresident (lt_dlhandle HANDLE)
+     Check whether a particular module has been marked as resident,
+     returning 1 if it has or 0 otherwise.  If there is an error while
+     executing this function, return -1 and set an error message for
+     retrieval with `lt_dlerror'.

+`-module' flag.

+
+11.2 Creating modules that can be `dlopen'ed
+============================================
+
+Libtool modules are created like normal libtool libraries with a few
+exceptions:
+
+   You have to link the module with libtool's `-module' switch, and you
+should link any program that is intended to dlopen the module with
+`-dlopen MODULENAME.LA' where possible, so that libtool can dlpreopen
+the module on platforms that do not support dlopening.  If the module
+depends on any other libraries, make sure you specify them either when
+you link the module or when you link programs that dlopen it.  If you
+want to disable versioning (*note Versioning::) for a specific module
+you should link it with the `-avoid-version' switch.  Note that libtool
+modules don't need to have a "lib" prefix.  However, Automake 1.4 or
+higher is required to build such modules.
+
+   Usually a set of modules provide the same interface, i.e. exports
+the same symbols, so that a program can dlopen them without having to
+know more about their internals: In order to avoid symbol conflicts all
+exported symbols must be prefixed with "modulename_LTX_" (MODULENAME is
+the name of the module).  Internal symbols must be named in such a way
+that they won't conflict with other modules, for example, by prefixing
+them with "_modulename_".  Although some platforms support having the
+same symbols defined more than once it is generally not portable and it
+makes it impossible to dlpreopen such modules.
+
+   libltdl will automatically cut the prefix off to get the real name of
+the symbol.  Additionally, it supports modules that do not use a prefix
+so that you can also dlopen non-libtool modules.
+
+   `foo1.c' gives an example of a portable libtool module.  Exported
+symbols are prefixed with "foo1_LTX_", internal symbols with "_foo1_".
+Aliases are defined at the beginning so that the code is more readable.
+
+     /* aliases for the exported symbols */
+     #define foo  foo1_LTX_foo
+     #define bar  foo1_LTX_bar
+
+     /* a global variable definition */
+     int bar = 1;
+
+     /* a private function */
+     int _foo1_helper() {
+       return bar;
+     }
+
+     /* an exported function */
+     int foo() {
+       return _foo1_helper();
+     }
+
+The `Makefile.am' contains the necessary rules to build the module
+`foo1.la':
+
+     ...
+     lib_LTLIBRARIES = foo1.la
+
+     foo1_la_SOURCES = foo1.c
+     foo1_la_LDFLAGS = -module
+     ...

+
+11.3 Using libltdl in a multi threaded environment
+==================================================
+
+Libltdl provides a wrapper around whatever dynamic run-time object
+loading mechanisms are provided by the host system, many of which are
+themselves not thread safe.  Consequently libltdl cannot itself be
+consistently thread safe.
+
+   If you wish to use libltdl in a multithreaded environment, then you
+must mutex lock around libltdl calls, since they may in turn be calling
+non-thread-safe system calls on some target hosts.
+
+   Some old releases of libtool provided a mutex locking API that was
+unusable with POSIX threads, so callers were forced to lock around all
+libltdl API calls anyway.  That mutex locking API was next to useless,
+and is not present in current releases.
+
+   Some future release of libtool may provide a new POSIX thread
+compliant mutex locking API.

+
+11.4 Data associated with loaded modules
+========================================
+
+Some of the internal information about each loaded module that is
+maintained by libltdl is available to the user, in the form of this
+structure:
+
+ -- Type: struct lt_dlinfo { char *FILENAME; char *NAME; int REF_COUNT;
+          int IS_RESIDENT; int IS_SYMGLOBAL; int IS_SYMLOCAL;}
+     `lt_dlinfo' is used to store information about a module.  The
+     FILENAME attribute is a null-terminated character string of the
+     real module file name.  If the module is a libtool module then
+     NAME is its module name (e.g. `"libfoo"' for `"dir/libfoo.la"'),
+     otherwise it is set to `NULL'.  The REF_COUNT attribute is a
+     reference counter that describes how often the same module is
+     currently loaded. The remaining fields can be compared to any
+     hints that were passed to `lt_dlopenadvise' to determine whether
+     the underlying loader was able to follow them.
+
+   The following function will return a pointer to libltdl's internal
+copy of this structure for the given HANDLE:
+
+ -- Function: const lt_dlinfo * lt_dlgetinfo (lt_dlhandle HANDLE)
+     Return a pointer to a struct that contains some information about
+     the module HANDLE.  The contents of the struct must not be
+     modified.  Return `NULL' on failure.
+
+   Furthermore, in order to save you from having to keep a list of the
+handles of all the modules you have loaded, these functions allow you to
+iterate over libltdl's list of loaded modules:
+
+ -- Type: lt_dlinterface_id
+     The opaque type used to hold the module interface details for each
+     registered libltdl client.
+
+ -- Type: int lt_dlhandle_interface (lt_dlhandle HANDLE,
+          const char *ID_STRING)
+     Functions of this type are called to check that a handle conforms
+     to a library's expected module interface when iterating over the
+     global handle list.  You should be careful to write a callback
+     function of this type that can correctly identify modules that
+     belong to this client, both to prevent other clients from
+     accidentally finding your loaded modules with the iterator
+     functions below, and vice versa.  The best way to do this is to
+     check that module HANDLE conforms to the interface specification
+     of your loader using `lt_dlsym'.
+
+     The callback may be given *every* module loaded by all the libltdl
+     module clients in the current address space, including any modules
+     loaded by other libraries such as libltdl itself, and should
+     return non-zero if that module does not fulfill the interface
+     requirements of your loader.

+
+ -- Function: lt_dlinterface_id lt_dlinterface_register
+          (const char *ID_STRING, lt_dlhandle_interface *IFACE)
+     Use this function to register your interface validator with
+     libltdl, and in return obtain a unique key to store and retrieve
+     per-module data.  You supply an ID_STRING and IFACE so that the
+     resulting `lt_dlinterface_id' can be used to filter the module
+     handles returned by the iteration functions below.  If IFACE is
+     `NULL', all modules will be matched.
+
+ -- Function: void lt_dlinterface_free (lt_dlinterface_id IFACE)
+     Release the data associated with IFACE.
+
+ -- Function: int lt_dlhandle_map (lt_dlinterface_id IFACE,
+          int (*FUNC) (lt_dlhandle HANDLE, void * DATA), void * DATA)
+     For each module that matches IFACE, call the function FUNC.  When
+     writing the FUNC callback function, the argument HANDLE is the
+     handle of a loaded module, and DATA is the last argument passed to
+     `lt_dlhandle_map'. As soon as FUNC returns a non-zero value for
+     one of the handles, `lt_dlhandle_map' will stop calling FUNC and
+     immediately return that non-zero value.  Otherwise 0 is eventually
+     returned when FUNC has been successfully called for all matching
+     modules.
+
+ -- Function: lt_dlhandle lt_dlhandle_iterate
+          (lt_dlinterface_id  IFACE, lt_dlhandle PLACE)
+     Iterate over the module handles loaded by IFACE, returning the
+     first matching handle in the list if PLACE is `NULL', and the next
+     one on subsequent calls.  If PLACE is the last element in the list
+     of eligible modules, this function returns `NULL'.
+
+          lt_dlhandle handle = 0;
+          lt_dlinterface_id iface = my_interface_id;
+
+          while ((handle = lt_dlhandle_iterate (iface, handle)))
+            {
+              ...
+            }
+
+ -- Function: lt_dlhandle lt_dlhandle_fetch (lt_dlinterface_id IFACE,
+          const char *MODULE_NAME)
+     Search through the module handles loaded by IFACE for a module
+     named MODULE_NAME, returning its handle if found or else `NULL' if
+     no such named module has been loaded by IFACE.
+
+   However, you might still need to maintain your own list of loaded
+module handles (in parallel with the list maintained inside libltdl) if
+there were any other data that your application wanted to associate
+with each open module.  Instead, you can use the following API calls to
+do that for you.  You must first obtain a unique interface id from
+libltdl as described above, and subsequently always use it to retrieve
+the data you stored earlier.  This allows different libraries to each
+store their own data against loaded modules, without interfering with
+one another.
+
+ -- Function: void * lt_dlcaller_set_data (lt_dlinterface_id KEY,
+          lt_dlhandle HANDLE, void * DATA)
+     Set DATA as the set of data uniquely associated with KEY and
+     HANDLE for later retrieval.  This function returns the DATA
+     previously associated with KEY and HANDLE if any.  A result of 0,
+     may indicate that a diagnostic for the last error (if any) is
+     available from `lt_dlerror()'.
+
+     For example, to correctly remove some associated data:
+
+          void *stale = lt_dlcaller_set_data (key, handle, 0);
+          if (stale != NULL)
+            {
+              free (stale);
+            }
+          else
+            {
+              char *error_msg = lt_dlerror ();
+
+              if (error_msg != NULL)
+                {
+                  my_error_handler (error_msg);
+                  return STATUS_FAILED;
+                }
+            }
+
+ -- Function: void * lt_dlcaller_get_data (lt_dlinterface_id KEY,
+          lt_dlhandle HANDLE)
+     Return the address of the data associated with KEY and HANDLE, or
+     else `NULL' if there is none.
+
+   Old versions of libltdl also provided a simpler, but similar, API
+based around `lt_dlcaller_id'.  Unfortunately, it had no provision for
+detecting whether a module belonged to a particular interface as
+libltdl didn't support multiple loaders in the same address space at
+that time.  Those APIs are no longer supported as there would be no way
+to stop clients of the old APIs from seeing (and accidentally altering)
+modules loaded by other libraries.

+
+11.5 How to create and register new module loaders
+==================================================
+
+Sometimes libltdl's many ways of gaining access to modules are not
+sufficient for the purposes of a project.  You can write your own
+loader, and register it with libltdl so that `lt_dlopen' will be able
+to use it.
+
+   Writing a loader involves writing at least three functions that can
+be called by `lt_dlopen', `lt_dlsym' and `lt_dlclose'.  Optionally, you
+can provide a finalisation function to perform any cleanup operations
+when `lt_dlexit' executes, and a symbol prefix string that will be
+prepended to any symbols passed to `lt_dlsym'.  These functions must
+match the function pointer types below, after which they can be
+allocated to an instance of `lt_user_dlloader' and registered.
+
+   Registering the loader requires that you choose a name for it, so
+that it can be recognised by `lt_dlloader_find' and removed with
+`lt_dlloader_remove'.  The name you choose must be unique, and not
+already in use by libltdl's builtin loaders:
+
+"dlopen"
+     The system dynamic library loader, if one exists.
+
+"dld"
+     The GNU dld loader, if `libdld' was installed when libltdl was
+     built.
+
+"dlpreload"
+     The loader for `lt_dlopen'ing of preloaded static modules.
+
+   The prefix "dl" is reserved for loaders supplied with future
+versions of libltdl, so you should not use that for your own loader
+names.
+
+The following types are defined in `ltdl.h':
+
+ -- Type: lt_module
+     `lt_module' is a dlloader dependent module.  The dynamic module
+     loader extensions communicate using these low level types.
+
+ -- Type: lt_dlloader
+     `lt_dlloader' is a handle for module loader types.
+
+ -- Type: lt_user_data
+     `lt_user_data' is used for specifying loader instance data.
+
+ -- Type: struct lt_user_dlloader {const char *SYM_PREFIX;
+          lt_module_open *MODULE_OPEN; lt_module_close *MODULE_CLOSE;
+          lt_find_sym *FIND_SYM; lt_dlloader_exit *DLLOADER_EXIT; }
+     If you want to define a new way to open dynamic modules, and have
+     the `lt_dlopen' API use it, you need to instantiate one of these
+     structures and pass it to `lt_dlloader_add'.  You can pass whatever
+     you like in the DLLOADER_DATA field, and it will be passed back as
+     the value of the first parameter to each of the functions
+     specified in the function pointer fields.
+
+ -- Type: lt_module lt_module_open (const char *FILENAME)
+     The type of the loader function for an `lt_dlloader' module
+     loader.  The value set in the dlloader_data field of the `struct
+     lt_user_dlloader' structure will be passed into this function in
+     the LOADER_DATA parameter.  Implementation of such a function
+     should attempt to load the named module, and return an `lt_module'
+     suitable for passing in to the associated `lt_module_close' and
+     `lt_sym_find' function pointers.  If the function fails it should
+     return `NULL', and set the error message with `lt_dlseterror'.
+
+ -- Type: int lt_module_close (lt_user_data LOADER_DATA,
+          lt_module MODULE)
+     The type of the unloader function for a user defined module loader.
+     Implementation of such a function should attempt to release any
+     resources tied up by the MODULE module, and then unload it from
+     memory.  If the function fails for some reason, set the error
+     message with `lt_dlseterror' and return non-zero.
+
+ -- Type: void * lt_find_sym (lt_module MODULE, const char *SYMBOL)
+     The type of the symbol lookup function for a user defined module
+     loader.  Implementation of such a function should return the
+     address of the named SYMBOL in the module MODULE, or else set the
+     error message with `lt_dlseterror' and return `NULL' if lookup
+     fails.
+
+ -- Type: int lt_dlloader_exit (lt_user_data LOADER_DATA)
+     The type of the finalisation function for a user defined module
+     loader.  Implementation of such a function should free any
+     resources associated with the loader, including any user specified
+     data in the `dlloader_data' field of the `lt_user_dlloader'.  If
+     non-`NULL', the function will be called by `lt_dlexit', and
+     `lt_dlloader_remove'.
+
+   For example:
+
+     int
+     register_myloader (void)
+     {
+       lt_user_dlloader dlloader;
+
+       /* User modules are responsible for their own initialisation. */
+       if (myloader_init () != 0)
+         return MYLOADER_INIT_ERROR;
+
+       dlloader.sym_prefix    = NULL;
+       dlloader.module_open   = myloader_open;
+       dlloader.module_close  = myloader_close;
+       dlloader.find_sym      = myloader_find_sym;
+       dlloader.dlloader_exit = myloader_exit;
+       dlloader.dlloader_data = (lt_user_data)myloader_function;
+
+       /* Add my loader as the default module loader. */
+       if (lt_dlloader_add (lt_dlloader_next (NULL), &dlloader,
+                            "myloader") != 0)
+         return ERROR;
+
+       return OK;
+     }
+
+   Note that if there is any initialisation required for the loader, it
+must be performed manually before the loader is registered - libltdl
+doesn't handle user loader initialisation.
+
+   Finalisation _is_ handled by libltdl however, and it is important to
+ensure the `dlloader_exit' callback releases any resources claimed
+during the initialisation phase.
+
+libltdl provides the following functions for writing your own module
+loaders:
+
+ -- Function: int lt_dlloader_add (lt_dlloader *PLACE,
+          lt_user_dlloader *DLLOADER, const char *LOADER_NAME)
+     Add a new module loader to the list of all loaders, either as the
+     last loader (if PLACE is `NULL'), else immediately before the
+     loader passed as PLACE.  LOADER_NAME will be returned by
+     `lt_dlloader_name' if it is subsequently passed a newly registered
+     loader.  These LOADER_NAMEs must be unique, or
+     `lt_dlloader_remove' and `lt_dlloader_find' cannot work.  Returns
+     0 for success.
+
+          /* Make myloader be the last one. */
+          if (lt_dlloader_add (NULL, myloader) != 0)
+            perror (lt_dlerror ());
+
+ -- Function: int lt_dlloader_remove (const char *LOADER_NAME)
+     Remove the loader identified by the unique name, LOADER_NAME.
+     Before this can succeed, all modules opened by the named loader
+     must have been closed.  Returns 0 for success, otherwise an error
+     message can be obtained from `lt_dlerror'.
+
+          /* Remove myloader. */
+          if (lt_dlloader_remove ("myloader") != 0)
+            perror (lt_dlerror ());
+
+ -- Function: lt_dlloader * lt_dlloader_next (lt_dlloader *PLACE)
+     Iterate over the module loaders, returning the first loader if
+     PLACE is `NULL', and the next one on subsequent calls.  The handle
+     is for use with `lt_dlloader_add'.
+
+          /* Make myloader be the first one. */
+          if (lt_dlloader_add (lt_dlloader_next (NULL), myloader) != 0)
+            return ERROR;
+
+ -- Function: lt_dlloader * lt_dlloader_find (const char *LOADER_NAME)
+     Return the first loader with a matching LOADER_NAME identifier, or
+     else `NULL', if the identifier is not found.
+
+     The identifiers that may be used by libltdl itself, if the host
+     architecture supports them are "dlopen"(1), "dld" and "dlpreload".
+
+          /* Add a user loader as the next module loader to be tried if
+             the standard dlopen loader were to fail when lt_dlopening. */
+          if (lt_dlloader_add (lt_dlloader_find ("dlopen"), myloader) != 0)
+            return ERROR;
+
+ -- Function: const char * lt_dlloader_name (lt_dlloader *PLACE)
+     Return the identifying name of PLACE, as obtained from
+     `lt_dlloader_next' or `lt_dlloader_find'.  If this function fails,
+     it will return `NULL' and set an error for retrieval with
+     `lt_dlerror'.
+
+ -- Function: lt_user_data * lt_dlloader_data (lt_dlloader *PLACE)
+     Return the address of the `dlloader_data' of PLACE, as obtained
+     from `lt_dlloader_next' or `lt_dlloader_find'.  If this function
+     fails, it will return `NULL' and set an error for retrieval with
+     `lt_dlerror'.
+
+11.5.1 Error handling within user module loaders
+------------------------------------------------
+
+ -- Function: int lt_dladderror (const char *DIAGNOSTIC)
+     This function allows you to integrate your own error messages into
+     `lt_dlerror'.  Pass in a suitable diagnostic message for return by
+     `lt_dlerror', and an error identifier for use with `lt_dlseterror'
+     is returned.
+
+     If the allocation of an identifier fails, this function returns -1.
+
+          int myerror = lt_dladderror ("Doh!");
+          if (myerror < 0)
+            perror (lt_dlerror ());
+
+ -- Function: int lt_dlseterror (int ERRORCODE)
+     When writing your own module loaders, you should use this function
+     to raise errors so that they are propagated through the
+     `lt_dlerror' interface.  All of the standard errors used by
+     libltdl are declared in `ltdl.h', or you can add more of your own
+     with `lt_dladderror'.  This function returns 0 on success.
+
+          if (lt_dlseterror (LTDL_ERROR_NO_MEMORY) != 0)
+            perror (lt_dlerror ());

+
+11.6 How to distribute libltdl with your package
+================================================
+
+Even though libltdl is installed together with libtool, you may wish to
+include libltdl in the distribution of your package, for the
+convenience of users of your package that don't have libtool or libltdl
+installed, or if you are using features of a very new version of
+libltdl that you don't expect your users to have yet.  In such cases,
+you must decide which flavor of libltdl you want to use: a convenience
+library or an installable libtool library.
+
+   The most simplistic way to add `libltdl' to your package is to copy
+all the `libltdl' source files to a subdirectory within your package
+and to build and link them along with the rest of your sources.  To
+help you do this, the m4 macros for Autoconf are available in
+`ltdl.m4'.  You must ensure that they are available in `aclocal.m4'
+before you run Autoconf(1).  Having made the macros available, you must
+add a call to the `LTDL_INIT' macro (after the call to `LT_INIT') to
+your package's `configure.ac' to perform the configure time checks
+required to build the library correctly.  Unfortunately, this method
+has problems if you then try to link the package binaries with an
+installed libltdl, or a library that depends on libltdl, because of the
+duplicate symbol definitions.  For example, ultimately linking against
+two different versions of libltdl, or against both a local convenience
+library and an installed libltdl is bad.  Ensuring that only one copy
+of the libltdl sources are linked into any program is left as an
+exercise for the reader.
+
+ -- Macro: LT_CONFIG_LTDL_DIR (DIRECTORY)
+     Declare DIRECTORY to be the location of the `libltdl' source
+     files, for `libtoolize --ltdl' to place them. *Note Invoking
+     libtoolize::, for more details.  Provided that you add an
+     appropriate `LT_CONFIG_LTDL_DIR' call in your `configure.ac'
+     before calling `libtoolize', the appropriate `libltdl' files will
+     be installed automatically.
+
+ -- Macro: LTDL_INIT (OPTIONS)
+ -- Macro: LT_WITH_LTDL
+ -- Macro: AC_WITH_LTDL
+     `AC_WITH_LTDL' and `LT_WITH_LTDL' are deprecated names for older
+     versions of this macro; `autoupdate' will update your
+     `configure.ac' file.
+
+     This macro adds the following options to the `configure' script:
+
+    `--with-ltdl-include INSTALLED-LTDL-HEADER-DIR'
+          The `LTDL_INIT' macro will look in the standard header file
+          locations to find the installed `libltdl' headers.  If
+          `LTDL_INIT' can't find them by itself, the person who builds
+          your package can use this option to tell `configure' where
+          the installed `libltdl' headers are.
+
+    `--with-ltdl-lib INSTALLED-LTDL-LIBRARY-DIR'
+          Similarly, the person building your package can use this
+          option to help `configure' find the installed `libltdl.la'.
+
+    `--with-included-ltdl'
+          If there is no installed `libltdl', or in any case if the
+          person building your package would rather use the `libltdl'
+          sources shipped with the package in the subdirectory named by
+          `LT_CONFIG_LTDL_DIR', they should pass this option to
+          `configure'.
+
+     If the `--with-included-ltdl' is not passed at configure time, and
+     an installed `libltdl' is not found(2), then `configure' will exit
+     immediately with an error that asks the user to either specify the
+     location of an installed `libltdl' using the `--with-ltdl-include'
+     and `--with-ltdl-lib' options, or to build with the `libltdl'
+     sources shipped with the package by passing `--with-included-ltdl'.
+
+     If an installed `libltdl' is found, then `LIBLTDL' is set to the
+     link flags needed to use it, and `LTDLINCL' to the preprocessor
+     flags needed to find the installed headers, and `LTDLDEPS' will be
+     empty.  Note, however, that no version checking is performed.  You
+     should manually check for the `libltdl' features you need in
+     `configure.ac':
+
+          LT_INIT([dlopen])
+          LTDL_INIT
+
+          # The lt_dladvise_init symbol was added with libtool-2.2
+          if test "x$with_included_ltdl" != "xyes"; then
+            save_CFLAGS="$CFLAGS"
+            save_LDFLAGS="$LDFLAGS"
+            CFLAGS="$CFLAGS $LTDLINCL"
+            LDFLAGS="$LDFLAGS $LIBLTDL"
+            AC_CHECK_LIB([ltdl], [lt_dladvise_init],
+                          [],
+                  [AC_MSG_ERROR([installed libltdl is too old])])
+            LDFLAGS="$save_LDFLAGS"
+            CFLAGS="$save_CFLAGS"
+          fi
+
+     OPTIONS may include no more than one of the following build modes
+     depending on how you want your project to build `libltdl':
+     `nonrecursive', `recursive', or `subproject'.  In order for
+     `libtoolize' to detect this option correctly, if you supply one of
+     these arguments, they must be given literally (i.e., macros or
+     shell variables that expand to the correct ltdl mode will not
+     work).
+
+    `nonrecursive'
+          This is how the Libtool project distribution builds the
+          `libltdl' we ship and install.  If you wish to use Automake
+          to build `libltdl' without invoking a recursive make to
+          descend into the `libltdl' subdirectory, then use this
+          option.  You will need to set your configuration up carefully
+          to make this work properly, and you will need releases of
+          Autoconf and Automake that support `subdir-objects' and
+          `LIBOBJDIR' properly.  In your `configure.ac', add:
+
+               AM_INIT_AUTOMAKE([subdir-objects])
+               AC_CONFIG_HEADERS([config.h])
+               LT_CONFIG_LTDL_DIR([libltdl])
+               LT_INIT([dlopen])
+               LTDL_INIT([nonrecursive])
+
+          You _have to_ use a config header, but it may have a name
+          different than `config.h'.
+
+          Also, add the following near the top of your `Makefile.am':
+
+               AM_CPPFLAGS =
+               AM_LDFLAGS =
+
+               BUILT_SOURCES =
+               EXTRA_DIST =
+               CLEANFILES =
+               MOSTLYCLEANFILES =
+
+               include_HEADERS =
+               noinst_LTLIBRARIES =
+               lib_LTLIBRARIES =
+               EXTRA_LTLIBRARIES =
+
+               include libltdl/Makefile.inc
+
+          Unless you build no other libraries from this `Makefile.am',
+          you will also need to change `lib_LTLIBRARIES' to assign with
+          `+=' so that the `libltdl' targets declared in `Makefile.inc'
+          are not overwritten.
+
+    `recursive'
+          This build mode still requires that you use Automake, but (in
+          contrast with `nonrecursive') uses the more usual device of
+          starting another `make' process in the `libltdl'
+          subdirectory.  To use this mode, you should add to your
+          `configure.ac':
+
+               AM_INIT_AUTOMAKE
+               AC_CONFIG_HEADERS([config.h])
+               LT_CONFIG_LTDL_DIR([libltdl])
+               LT_INIT([dlopen])
+               LTDL_INIT([recursive])
+               AC_CONFIG_FILES([libltdl/Makefile])
+
+          Again, you _have to_ use a config header, but it may have a
+          name different than `config.h' if you like.
+
+          Also, add this to your `Makefile.am':
+
+               SUBDIRS = libltdl
+
+    `subproject'
+          This mode is the default unless you explicitly add
+          `recursive' or `nonrecursive' to your `LTDL_INIT' options;
+          `subproject' is the only mode supported by previous releases
+          of libltdl.  Even if you do not use Autoconf in the parent
+          project, then, in `subproject' mode, still `libltdl' contains
+          all the necessary files to configure and build itself - you
+          just need to arrange for your build system to call
+          `libltdl/configure' with appropriate options, and then run
+          `make' in the `libltdl' subdirectory.
+
+          If you _are_ using Autoconf and Automake, then you will need
+          to add the following to your `configure.ac':
+
+               LT_CONFIG_LTDL_DIR([libltdl])
+               LTDL_INIT
+
+          and to `Makefile.am':
+
+               SUBDIRS = libltdl
+
+     Aside from setting the libltdl build mode, there are other keywords
+     that you can pass to `LTDL_INIT' to modify its behavior when
+     `--with-included-ltdl' has been given:
+
+    `convenience'
+          This is the default unless you explicitly add `installable' to
+          your `LTDL_INIT' options.
+
+          This keyword will cause options to be passed to the
+          `configure' script in the subdirectory named by
+          `LT_CONFIG_LTDL_DIR' in order to cause it to be built as a
+          convenience library.  If you're not using automake, you will
+          need to define `top_build_prefix', `top_builddir', and
+          `top_srcdir' in your makefile so that `LIBLTDL', `LTDLDEPS',
+          and `LTDLINCL' expand correctly.
+
+          One advantage of the convenience library is that it is not
+          installed, so the fact that you use `libltdl' will not be
+          apparent to the user, and it won't overwrite a pre-installed
+          version of `libltdl' the system might already have in the
+          installation directory.  On the other hand, if you want to
+          upgrade `libltdl' for any reason (e.g. a bugfix) you'll have
+          to recompile your package instead of just replacing the
+          shared installed version of `libltdl'.  However, if your
+          programs or libraries are linked with other libraries that
+          use such a pre-installed version of `libltdl', you may get
+          linker errors or run-time crashes.  Another problem is that
+          you cannot link the convenience library into more than one
+          libtool library, then link a single program with those
+          libraries, because you may get duplicate symbols.  In general
+          you can safely use the convenience library in programs that
+          don't depend on other libraries that might use `libltdl' too.
+
+    `installable'
+          This keyword will pass options to the `configure' script in
+          the subdirectory named by `LT_CONFIG_LTDL_DIR' in order to
+          cause it to be built as an installable library.  If you're not
+          using automake, you will need to define `top_build_prefix',
+          `top_builddir' and `top_srcdir' in your makefile so that
+          `LIBLTDL', `LTDLDEPS', and `LTDLINCL' are expanded properly.
+
+          Be aware that you could overwrite another `libltdl' already
+          installed to the same directory if you use this option.
+
+   Whatever method you use, `LTDL_INIT' will define the shell variable
+`LIBLTDL' to the link flag that you should use to link with `libltdl',
+the shell variable `LTDLDEPS' to the files that can be used as a
+dependency in `Makefile' rules, and the shell variable `LTDLINCL' to
+the preprocessor flag that you should use to compile programs that
+include `ltdl.h'. So, when you want to link a program with libltdl, be
+it a convenience, installed or installable library, just use
+`$(LTDLINCL)' for preprocessing and compilation, and `$(LIBLTDL)' for
+linking.
+
+   * If your package is built using an installed version of `libltdl',
+     `LIBLTDL' will be set to the compiler flags needed to link against
+     the installed library, `LTDLDEPS' will be empty, and `LTDLINCL'
+     will be set to the compiler flags needed to find the `libltdl'
+     header files.
+
+   * If your package is built using the convenience libltdl, `LIBLTDL'
+     and `LTDLDEPS' will be the pathname for the convenience version of
+     libltdl (starting with `${top_builddir}/' or
+     `${top_build_prefix}') and `LTDLINCL' will be `-I' followed by the
+     directory that contains `ltdl.h' (starting with `${top_srcdir}/').
+
+   * If an installable version of the included `libltdl' is being
+     built, its pathname starting with `${top_builddir}/' or
+     `${top_build_prefix}', will be stored in `LIBLTDL' and `LTDLDEPS',
+     and `LTDLINCL' will be set just like in the case of convenience
+     library.
+
+   You should probably also use the `dlopen' option to `LT_INIT' in
+your `configure.ac', otherwise libtool will assume no dlopening
+mechanism is supported, and revert to dlpreopening, which is probably
+not what you want.  Avoid using the `-static', `-static-libtool-libs',
+or `-all-static' switches when linking programs with libltdl.  This
+will not work on all platforms, because the dlopening functions may not
+be available for static linking.
+
+   The following example shows you how to embed an installable libltdl
+in your package.  In order to use the convenience variant, just replace
+the `LTDL_INIT' option `installable' with `convenience'.  We assume
+that libltdl was embedded using `libtoolize --ltdl'.
+
+   configure.ac:
+     ...
+     # Name the subdirectory that contains libltdl sources
+     LT_CONFIG_LTDL_DIR([libltdl])
+
+     # Configure libtool with dlopen support if possible
+     LT_INIT([dlopen])
+
+     # Enable building of the installable libltdl library
+     LTDL_INIT([installable])
+     ...
+
+   Makefile.am:
+     ...
+     SUBDIRS = libltdl
+
+     AM_CPPFLAGS = $(LTDLINCL)
+
+     myprog_LDFLAGS = -export-dynamic
+     myprog_LDADD = $(LIBLTDL) -dlopen self -dlopen foo1.la
+     myprog_DEPENDENCIES = $(LTDLDEPS) foo1.la
+     ...

+
+   (1) We used to recommend adding the contents of `ltdl.m4' to
+`acinclude.m4', but with `aclocal' from a modern Automake (1.8 or
+newer) and this release of libltdl that is not only unnecessary but
+makes it easy to forget to upgrade `acinclude.m4' if you move to a
+different release of libltdl.
+
+   (2) Even if libltdl is installed, `LTDL_INIT' may fail to detect it
+if libltdl depends on symbols provided by libraries other than the C
+library.

+****************************
+
+This section describes macros whose sole purpose is to be traced using
+Autoconf's `--trace' option (*note The Autoconf Manual:
+(autoconf)autoconf Invocation.) to query the Libtool configuration of a
+project.  These macros are called by Libtool internals and should never
+be called by user code; they should only be traced.
+
+ -- Macro: LT_SUPPORTED_TAG (TAG)
+     This macro is called once for each language enabled in the
+     package.  Its only argument, TAG, is the tag-name corresponding to
+     the language (*note Tags::).
+
+     You can therefore retrieve the list of all tags enabled in a
+     project using the following command:
+          autoconf --trace 'LT_SUPPORTED_TAG:$1'

+

+File: libtool.info,  Node: Stripped link flags,  Up: FAQ
+
+13.1 Why does libtool strip link flags when creating a library?
+===============================================================
+
+When creating a shared library, but not when compiling or creating a
+program, `libtool' drops some flags from the command line provided by
+the user.  This is done because flags unknown to `libtool' may
+interfere with library creation or require additional support from
+`libtool', and because omitting flags is usually the conservative
+choice for a successful build.
+
+   If you encounter flags that you think are useful to pass, as a
+work-around you can prepend flags with `-Wc,' or `-Xcompiler ' to allow
+them to be passed through to the compiler driver (*note Link mode::).
+Another possibility is to add flags already to the compiler command at
+`configure' run time:
+
+     ./configure CC='gcc -m64'
+
+   If you think `libtool' should let some flag through by default,
+here's how you can test such an inclusion: grab the Libtool development
+tree, edit the `ltmain.m4sh' file in the `libltdl/config' subdirectory
+to pass through the flag (search for `Flags to be passed through'),
+re-bootstrap and build with the flags in question added to `LDFLAGS',
+`CFLAGS', `CXXFLAGS', etc. on the `configure' command line as
+appropriate.  Run the testsuite as described in the `README' file and
+report results to the Libtool bug reporting address
+<bug-libtool@gnu.org>.

+
+14.1 The libtool test suite
+===========================
+
+Libtool comes with two integrated sets of tests to check that your build
+is sane, that test its capabilities, and report obvious bugs in the
+libtool program.  These tests, too, are constantly evolving, based on
+past problems with libtool, and known deficiencies in other operating
+systems.
+
+   As described in the `README' file, you may run `make -k check' after
+you have built libtool (possibly before you install it) in order to
+make sure that it meets basic functional requirements.

+
+14.1.1 Description of test suite
+--------------------------------
+
+Here is a list of the current programs in the old test suite, and what
+they test for:
+
+`cdemo-conf.test'
+`cdemo-make.test'
+`cdemo-exec.test'
+`cdemo-static.test'
+`cdemo-static-make.test'
+`cdemo-static-exec.test'
+`cdemo-shared.test'
+`cdemo-shared-make.test'
+`cdemo-shared-exec.test'
+`cdemo-undef.test'
+`cdemo-undef-make.test'
+`cdemo-undef-exec.test'
+     These programs check to see that the `tests/cdemo' subdirectory of
+     the libtool distribution can be configured and built correctly.
+
+     The `tests/cdemo' subdirectory contains a demonstration of libtool
+     convenience libraries, a mechanism that allows build-time static
+     libraries to be created, in a way that their components can be
+     later linked into programs or other libraries, even shared ones.
+
+     The tests matching `cdemo-*make.test' and `cdemo-*exec.test' are
+     executed three times, under three different libtool configurations:
+     `cdemo-conf.test' configures `cdemo/libtool' to build both static
+     and shared libraries (the default for platforms that support
+     both), `cdemo-static.test' builds only static libraries
+     (`--disable-shared'), and `cdemo-shared.test' builds only shared
+     libraries (`--disable-static').
+
+     The test `cdemo-undef.test' tests the generation of shared
+     libraries with undefined symbols on systems that allow this.
+
+`demo-conf.test'
+`demo-make.test'
+`demo-exec.test'
+`demo-inst.test'
+`demo-unst.test'
+`demo-static.test'
+`demo-static-make.test'
+`demo-static-exec.test'
+`demo-static-inst.test'
+`demo-static-unst.test'
+`demo-shared.test'
+`demo-shared-make.test'
+`demo-shared-exec.test'
+`demo-shared-inst.test'
+`demo-shared-unst.test'
+`demo-nofast.test'
+`demo-nofast-make.test'
+`demo-nofast-exec.test'
+`demo-nofast-inst.test'
+`demo-nofast-unst.test'
+`demo-pic.test'
+`demo-pic-make.test'
+`demo-pic-exec.test'
+`demo-nopic.test'
+`demo-nopic-make.test'
+`demo-nopic-exec.test'
+     These programs check to see that the `tests/demo' subdirectory of
+     the libtool distribution can be configured, built, installed, and
+     uninstalled correctly.
+
+     The `tests/demo' subdirectory contains a demonstration of a trivial
+     package that uses libtool.  The tests matching `demo-*make.test',
+     `demo-*exec.test', `demo-*inst.test' and `demo-*unst.test' are
+     executed four times, under four different libtool configurations:
+     `demo-conf.test' configures `demo/libtool' to build both static
+     and shared libraries, `demo-static.test' builds only static
+     libraries (`--disable-shared'), and `demo-shared.test' builds only
+     shared libraries (`--disable-static').  `demo-nofast.test'
+     configures `demo/libtool' to disable the fast-install mode
+     (`--enable-fast-install=no').  `demo-pic.test' configures
+     `demo/libtool' to prefer building PIC code (`--with-pic'),
+     `demo-nopic.test' to prefer non-PIC code (`--without-pic').
+
+`demo-deplibs.test'
+     Many systems cannot link static libraries into shared libraries.
+     libtool uses a `deplibs_check_method' to prevent such cases.  This
+     tests checks whether libtool's `deplibs_check_method' works
+     properly.
+
+`demo-hardcode.test'
+     On all systems with shared libraries, the location of the library
+     can be encoded in executables that are linked against it *note
+     Linking executables::.  This test checks the conditions under
+     which your system linker hardcodes the library location, and
+     guarantees that they correspond to libtool's own notion of how
+     your linker behaves.
+
+`demo-relink.test'
+`depdemo-relink.test'
+     These tests check whether variable `shlibpath_overrides_runpath' is
+     properly set.  If the test fails, it will indicate what the
+     variable should have been set to.
+
+`demo-noinst-link.test'
+     Checks whether libtool will not try to link with a previously
+     installed version of a library when it should be linking with a
+     just-built one.
+
+`depdemo-conf.test'
+`depdemo-make.test'
+`depdemo-exec.test'
+`depdemo-inst.test'
+`depdemo-unst.test'
+`depdemo-static.test'
+`depdemo-static-make.test'
+`depdemo-static-exec.test'
+`depdemo-static-inst.test'
+`depdemo-static-unst.test'
+`depdemo-shared.test'
+`depdemo-shared-make.test'
+`depdemo-shared-exec.test'
+`depdemo-shared-inst.test'
+`depdemo-shared-unst.test'
+`depdemo-nofast.test'
+`depdemo-nofast-make.test'
+`depdemo-nofast-exec.test'
+`depdemo-nofast-inst.test'
+`depdemo-nofast-unst.test'
+     These programs check to see that the `tests/depdemo' subdirectory
+     of the libtool distribution can be configured, built, installed,
+     and uninstalled correctly.
+
+     The `tests/depdemo' subdirectory contains a demonstration of
+     inter-library dependencies with libtool.  The test programs link
+     some interdependent libraries.
+
+     The tests matching `depdemo-*make.test', `depdemo-*exec.test',
+     `depdemo-*inst.test' and `depdemo-*unst.test' are executed four
+     times, under four different libtool configurations:
+     `depdemo-conf.test' configures `depdemo/libtool' to build both
+     static and shared libraries, `depdemo-static.test' builds only
+     static libraries (`--disable-shared'), and `depdemo-shared.test'
+     builds only shared libraries (`--disable-static').
+     `depdemo-nofast.test' configures `depdemo/libtool' to disable the
+     fast-install mode (`--enable-fast-install=no').
+
+`mdemo-conf.test'
+`mdemo-make.test'
+`mdemo-exec.test'
+`mdemo-inst.test'
+`mdemo-unst.test'
+`mdemo-static.test'
+`mdemo-static-make.test'
+`mdemo-static-exec.test'
+`mdemo-static-inst.test'
+`mdemo-static-unst.test'
+`mdemo-shared.test'
+`mdemo-shared-make.test'
+`mdemo-shared-exec.test'
+`mdemo-shared-inst.test'
+`mdemo-shared-unst.test'
+     These programs check to see that the `tests/mdemo' subdirectory of
+     the libtool distribution can be configured, built, installed, and
+     uninstalled correctly.
+
+     The `tests/mdemo' subdirectory contains a demonstration of a
+     package that uses libtool and the system independent dlopen wrapper
+     `libltdl' to load modules.  The library `libltdl' provides a
+     dlopen wrapper for various platforms (POSIX) including support for
+     dlpreopened modules (*note Dlpreopening::).
+
+     The tests matching `mdemo-*make.test', `mdemo-*exec.test',
+     `mdemo-*inst.test' and `mdemo-*unst.test' are executed three
+     times, under three different libtool configurations:
+     `mdemo-conf.test' configures `mdemo/libtool' to build both static
+     and shared libraries, `mdemo-static.test' builds only static
+     libraries (`--disable-shared'), and `mdemo-shared.test' builds
+     only shared libraries (`--disable-static').
+
+`mdemo-dryrun.test'
+     This test checks whether libtool's `--dry-run' mode works properly.
+
+`mdemo2-conf.test'
+`mdemo2-exec.test'
+`mdemo2-make.test'
+     These programs check to see that the `tests/mdemo2' subdirectory of
+     the libtool distribution can be configured, built, and executed
+     correctly.
+
+     The `tests/mdemo2' directory contains a demonstration of a package
+     that attempts to link with a library (from the `tests/mdemo'
+     directory) that itself does dlopening of libtool modules.
+
+`link.test'
+     This test guarantees that linking directly against a non-libtool
+     static library works properly.
+
+`link-2.test'
+     This test makes sure that files ending in `.lo' are never linked
+     directly into a program file.
+
+`nomode.test'
+     Check whether we can actually get help for libtool.
+
+`objectlist.test'
+     Check that a nonexistent objectlist file is properly detected.
+
+`pdemo-conf.test'
+`pdemo-make.test'
+`pdemo-exec.test'
+`pdemo-inst.test'
+     These programs check to see that the `tests/pdemo' subdirectory of
+     the libtool distribution can be configured, built, and executed
+     correctly.
+
+     The `pdemo-conf.test' lowers the `max_cmd_len' variable in the
+     generated libtool script to test the measures to evade command line
+     length limitations.
+
+`quote.test'
+     This program checks libtool's metacharacter quoting.
+
+`sh.test'
+     Checks for some nonportable or dubious or undesired shell
+     constructs in shell scripts.
+
+`suffix.test'
+     When other programming languages are used with libtool (*note
+     Other languages::), the source files may end in suffixes other
+     than `.c'.  This test validates that libtool can handle suffixes
+     for all the file types that it supports, and that it fails when
+     the suffix is invalid.
+
+`tagdemo-conf.test'
+`tagdemo-make.test'
+`tagdemo-exec.test'
+`tagdemo-static.test'
+`tagdemo-static-make.test'
+`tagdemo-static-exec.test'
+`tagdemo-shared.test'
+`tagdemo-shared-make.test'
+`tagdemo-shared-exec.test'
+`tagdemo-undef.test'
+`tagdemo-undef-make.test'
+`tagdemo-undef-exec.test'
+     These programs check to see that the `tests/tagdemo' subdirectory
+     of the libtool distribution can be configured, built, and executed
+     correctly.
+
+     The `tests/tagdemo' directory contains a demonstration of a package
+     that uses libtool's multi-language support through configuration
+     tags.  It generates a library from C++ sources, which is then
+     linked to a C++ program.
+
+`f77demo-conf.test'
+`f77demo-make.test'
+`f77demo-exec.test'
+`f77demo-static.test'
+`f77demo-static-make.test'
+`f77demo-static-exec.test'
+`f77demo-shared.test'
+`f77demo-shared-make.test'
+`f77demo-shared-exec.test'
+     These programs check to see that the `tests/f77demo' subdirectory
+     of the libtool distribution can be configured, built, and executed
+     correctly.
+
+     The `tests/f77demo' tests test Fortran 77 support in libtool by
+     creating libraries from Fortran 77 sources, and mixed Fortran and C
+     sources, and a Fortran 77 program to use the former library, and a
+     C program to use the latter library.
+
+`fcdemo-conf.test'
+`fcdemo-make.test'
+`fcdemo-exec.test'
+`fcdemo-static.test'
+`fcdemo-static-make.test'
+`fcdemo-static-exec.test'
+`fcdemo-shared.test'
+`fcdemo-shared-make.test'
+`fcdemo-shared-exec.test'
+     These programs check to see that the `tests/fcdemo' subdirectory
+     of the libtool distribution can be configured, built, and executed
+     correctly.
+
+     The `tests/fcdemo' is similar to the `tests/f77demo' directory,
+     except that Fortran 90 is used in combination with the `FC'
+     interface provided by Autoconf and Automake.
+
+
+   The new, Autotest-based test suite uses keywords to classify certain
+test groups:
+
+`CXX'
+`F77'
+`FC'
+`GCJ'
+     The test group exercises one of these `libtool' language tags.
+
+`autoconf'
+`automake'
+     These keywords denote that the respective external program is
+     needed by the test group.  The tests are typically skipped if the
+     program is not installed.  The `automake' keyword may also denote
+     use of the `aclocal' program.
+
+`interactive'
+     This test group may require user interaction on some systems.
+     Typically, this means closing a popup window about a DLL load
+     error on Windows.
+
+`libltdl'
+     Denote that the `libltdl' library is exercised by the test group.
+
+`libtool'
+`libtoolize'
+     Denote that the `libtool' or `libtoolize' scripts are exercised by
+     the test group, respectively.
+
+`recursive'
+     Denote that this test group may recursively re-invoke the test
+     suite itself, with changed settings and maybe a changed `libtool'
+     script.  You may use the `INNER_TESTSUITEFLAGS' variable to pass
+     additional settings to this recursive invocation.  Typically,
+     recursive invocations delimit the set of tests with another
+     keyword, for example by passing `-k libtool' right before the
+     expansion of the `INNER_TESTSUITEFLAGS' variable (without an
+     intervening space, so you get the chance for further delimitation).
+
+     Test groups with the keyword `recursive' should not be denoted with
+     keywords, in order to avoid infinite recursion.  As a consequence,
+     recursive test groups themselves should never require user
+     interaction, while the test groups they invoke may do so.
+
+   There is a convenience target `check-noninteractive' that runs all
+tests from both test suites that do not cause user interaction on
+Windows.  Conversely, the target `check-interactive' runs the
+complement of tests and might require closing popup windows about DLL
+load errors on Windows.

+
+14.1.2 When tests fail
+----------------------
+
+When the tests in the old test suite are run via `make check', output
+is caught in per-test `tests/TEST-NAME.log' files and summarized in the
+`test-suite.log' file.  The exit status of each program tells the
+`Makefile' whether or not the test succeeded.
+
+   If a test fails, it means that there is either a programming error in
+libtool, or in the test program itself.
+
+   To investigate a particular test, you may run it directly, as you
+would a normal program.  When the test is invoked in this way, it
+produces output that may be useful in determining what the problem is.
+
+   The new, Autotest-based test suite produces as output a file
+`tests/testsuite.log' which contains information about failed tests.
+
+   You can pass options to the test suite through the `make' variable
+`TESTSUITEFLAGS' (*note The Autoconf Manual: (autoconf)testsuite
+Invocation.).

+14.2 Reporting bugs
+===================
+
+If you think you have discovered a bug in libtool, you should think
+twice: the libtool maintainer is notorious for passing the buck (or
+maybe that should be "passing the bug").  Libtool was invented to fix
+known deficiencies in shared library implementations, so, in a way, most
+of the bugs in libtool are actually bugs in other operating systems.
+However, the libtool maintainer would definitely be happy to add support
+for somebody else's buggy operating system.  [I wish there was a good
+way to do winking smiley-faces in Texinfo.]
+
+   Genuine bugs in libtool include problems with shell script
+portability, documentation errors, and failures in the test suite
+(*note Libtool test suite::).
+
+   First, check the documentation and help screens to make sure that the
+behaviour you think is a problem is not already mentioned as a feature.
+
+   Then, you should read the Emacs guide to reporting bugs (*note
+Reporting Bugs: (emacs)Bugs.).  Some of the details listed there are
+specific to Emacs, but the principle behind them is a general one.
+
+   Finally, send a bug report to the Libtool bug reporting address
+<bug-libtool@gnu.org> with any appropriate _facts_, such as test suite
+output (*note When tests fail::), all the details needed to reproduce
+the bug, and a brief description of why you think the behaviour is a
+bug.  Be sure to include the word "libtool" in the subject line, as
+well as the version number you are using (which can be found by typing
+`libtool --version').

+15.1 Porting libtool to new systems
+===================================
+
+Before you embark on porting libtool to an unsupported system, it is
+worthwhile to send e-mail to the Libtool mailing list
+<libtool@gnu.org>, to make sure that you are not duplicating existing
+work.
+
+   If you find that any porting documentation is missing, please
+complain!  Complaints with patches and improvements to the
+documentation, or to libtool itself, are more than welcome.

+
+15.1.1 Information sources
+--------------------------
+
+Once it is clear that a new port is necessary, you'll generally need the
+following information:
+
+canonical system name
+     You need the output of `config.guess' for this system, so that you
+     can make changes to the libtool configuration process without
+     affecting other systems.
+
+man pages for `ld' and `cc'
+     These generally describe what flags are used to generate PIC, to
+     create shared libraries, and to link against only static
+     libraries.  You may need to follow some cross references to find
+     the information that is required.
+
+man pages for `ld.so', `rtld', or equivalent
+     These are a valuable resource for understanding how shared
+     libraries are loaded on the system.
+
+man page for `ldconfig', or equivalent
+     This page usually describes how to install shared libraries.
+
+output from `ls -l /lib /usr/lib'
+     This shows the naming convention for shared libraries on the
+     system, including which names should be symbolic links.
+
+any additional documentation
+     Some systems have special documentation on how to build and install
+     shared libraries.
+
+   If you know how to program the Bourne shell, then you can complete
+the port yourself; otherwise, you'll have to find somebody with the
+relevant skills who will do the work.  People on the libtool mailing
+list are usually willing to volunteer to help you with new ports, so
+you can send the information to them.
+
+   To do the port yourself, you'll definitely need to modify the
+`libtool.m4' macros in order to make platform-specific changes to the
+configuration process.  You should search that file for the `PORTME'
+keyword, which will give you some hints on what you'll need to change.
+In general, all that is involved is modifying the appropriate
+configuration variables (*note libtool script contents::).
+
+   Your best bet is to find an already-supported system that is similar
+to yours, and make your changes based on that.  In some cases, however,
+your system will differ significantly from every other supported system,
+and it may be necessary to add new configuration variables, and modify
+the `ltmain.in' script accordingly.  Be sure to write to the mailing
+list before you make changes to `ltmain.in', since they may have advice
+on the most effective way of accomplishing what you want.

+
+15.1.2 Porting inter-library dependencies support
+-------------------------------------------------
+
+Since version 1.2c, libtool has re-introduced the ability to do
+inter-library dependency on some platforms, thanks to a patch by Toshio
+Kuratomi <badger@prtr-13.ucsc.edu>.  Here's a shortened version of the
+message that contained his patch:
+
+   The basic architecture is this: in `libtool.m4', the person who
+writes libtool makes sure `$deplibs' is included in `$archive_cmds'
+somewhere and also sets the variable `$deplibs_check_method', and maybe
+`$file_magic_cmd' when `deplibs_check_method' is file_magic.
+
+   `deplibs_check_method' can be one of five things:
+`file_magic [REGEX]'
+     looks in the library link path for libraries that have the right
+     libname.  Then it runs `$file_magic_cmd' on the library and checks
+     for a match against the extended regular expression REGEX.  When
+     `file_magic_test_file' is set by `libtool.m4', it is used as an
+     argument to `$file_magic_cmd' in order to verify whether the
+     regular expression matches its output, and warn the user otherwise.
+
+`test_compile'
+     just checks whether it is possible to link a program out of a list
+     of libraries, and checks which of those are listed in the output of
+     `ldd'.  It is currently unused, and will probably be dropped in the
+     future.
+
+`pass_all'
+     will pass everything without any checking.  This may work on
+     platforms in which code is position-independent by default and
+     inter-library dependencies are properly supported by the dynamic
+     linker, for example, on DEC OSF/1 3 and 4.
+
+`none'
+     It causes deplibs to be reassigned `deplibs=""'.  That way
+     `archive_cmds' can contain deplibs on all platforms, but not have
+     deplibs used unless needed.
+
+`unknown'
+     is the default for all systems unless overridden in `libtool.m4'.
+     It is the same as `none', but it documents that we really don't
+     know what the correct value should be, and we welcome patches that
+     improve it.
+
+   Then in `ltmain.in' we have the real workhorse: a little
+initialization and postprocessing (to setup/release variables for use
+with eval echo libname_spec etc.) and a case statement that decides the
+method that is being used.  This is the real code... I wish I could
+condense it a little more, but I don't think I can without function
+calls.  I've mostly optimized it (moved things out of loops, etc.) but
+there is probably some fat left.  I thought I should stop while I was
+ahead, work on whatever bugs you discover, etc. before thinking about
+more than obvious optimizations.

+
+15.3.2 Compilers
+----------------
+
+The only compiler characteristics that affect libtool are the flags
+needed (if any) to generate PIC objects.  In general, if a C compiler
+supports certain PIC flags, then any derivative compilers support the
+same flags.  Until there are some noteworthy exceptions to this rule,
+this section will document only C compilers.
+
+   The following C compilers have standard command line options,
+regardless of the platform:
+
+`gcc'
+     This is the GNU C compiler, which is also the system compiler for
+     many free operating systems (FreeBSD, GNU/Hurd, GNU/Linux, Lites,
+     NetBSD, and OpenBSD, to name a few).
+
+     The `-fpic' or `-fPIC' flags can be used to generate
+     position-independent code.  `-fPIC' is guaranteed to generate
+     working code, but the code is slower on m68k, m88k, and Sparc
+     chips.  However, using `-fpic' on those chips imposes arbitrary
+     size limits on the shared libraries.
+
+   The rest of this subsection lists compilers by the operating system
+that they are bundled with:
+
+`aix3*'
+`aix4*'
+     Most AIX compilers have no PIC flags, since AIX (with the
+     exception of AIX for IA-64) runs on PowerPC and RS/6000 chips. (1)
+
+`hpux10*'
+     Use `+Z' to generate PIC.
+
+`osf3*'
+     Digital/UNIX 3.x does not have PIC flags, at least not on the
+     PowerPC platform.
+
+`solaris2*'
+     Use `-KPIC' to generate PIC.
+
+`sunos4*'
+     Use `-PIC' to generate PIC.
+
+   ---------- Footnotes ----------
+
+   (1) All code compiled for the PowerPC and RS/6000 chips
+(`powerpc-*-*', `powerpcle-*-*', and `rs6000-*-*') is
+position-independent, regardless of the operating system or compiler
+suite.  So, "regular objects" can be used to build shared libraries on
+these systems and no special PIC compiler flags are required.

+
+15.3.3 Reloadable objects
+-------------------------
+
+On all known systems, a reloadable object can be created by running `ld
+-r -o OUTPUT.o INPUT1.o INPUT2.o'.  This reloadable object may be
+treated as exactly equivalent to other objects.
+
+
+File: libtool.info,  Node: Multiple dependencies,  Next: Archivers,  Prev: Reloadable objects,  Up: Platform quirks
+
+15.3.4 Multiple dependencies
+----------------------------
+
+On most modern platforms the order in which dependent libraries are
+listed has no effect on object generation.  In theory, there are
+platforms that require libraries that provide missing symbols to other
+libraries to be listed after those libraries whose symbols they provide.
+
+   Particularly, if a pair of static archives each resolve some of the
+other's symbols, it might be necessary to list one of those archives
+both before and after the other one.  Libtool does not currently cope
+with this situation well, since duplicate libraries are removed from
+the link line by default.  Libtool provides the command line option
+`--preserve-dup-deps' to preserve all duplicate dependencies in cases
+where it is necessary.
+
+
+File: libtool.info,  Node: Archivers,  Next: Cross compiling,  Prev: Multiple dependencies,  Up: Platform quirks
+
+15.3.5 Archivers
+----------------
+
+On all known systems, building a static library can be accomplished by
+running `ar cru libNAME.a OBJ1.o OBJ2.o ...', where the `.a' file is
+the output library, and each `.o' file is an object file.
+
+   On all known systems, if there is a program named `ranlib', then it
+must be used to "bless" the created library before linking against it,
+with the `ranlib libNAME.a' command.  Some systems, like Irix, use the
+`ar ts' command, instead.
+
+
+File: libtool.info,  Node: Cross compiling,  Next: File name conversion,  Prev: Archivers,  Up: Platform quirks
+
+15.3.6 Cross compiling
+----------------------
+
+Most build systems support the ability to compile libraries and
+applications on one platform for use on a different platform, provided
+a compiler capable of generating the appropriate output is available.
+In such cross compiling scenarios, the platform on which the libraries
+or applications are compiled is called the "build platform", while the
+platform on which the libraries or applications are intended to be used
+or executed is called the "host platform".  *note The GNU Build System:
+(automake)GNU Build System, of which libtool is a part, supports cross
+compiling via arguments passed to the configure script: `--build=...'
+and `--host=...'. However, when the build platform and host platform
+are very different, libtool is required to make certain accommodations
+to support these scenarios.
+
+   In most cases, because the build platform and host platform differ,
+the cross-compiled libraries and executables can't be executed or
+tested on the build platform where they were compiled.  The testsuites
+of most build systems will often skip any tests that involve executing
+such foreign executables when cross-compiling.  However, if the build
+platform and host platform are sufficiently similar, it is often
+possible to run cross-compiled applications.  Libtool's own testsuite
+often attempts to execute cross-compiled tests, but will mark any
+failures as _skipped_ since the failure might simply be due to the
+differences between the two platforms.
+
+   In addition to cases where the host platform and build platform are
+extremely similar (e.g. `i586-pc-linux-gnu' and `i686-pc-linux-gnu'),
+there is another case in which cross-compiled host applications may be
+executed on the build platform.  This is possible when the build
+platform supports an emulation or API-enhanced environment for the host
+platform.  One example of this situation would be if the build platform
+were MinGW, and the host platform were Cygwin (or vice versa).  Both of
+these platforms can actually operate within a single Windows instance,
+so Cygwin applications can be launched from a MinGW context, and vice
+versa--provided certain care is taken.  Another example would be if the
+build platform were GNU/Linux on an x86 32bit processor, and the host
+platform were MinGW.  In this situation, the Wine
+(http://www.winehq.org/) environment can be used to launch Windows
+applications from the GNU/Linux operating system; again, provided
+certain care is taken.
+
+   One particular issue occurs when a Windows platform such as MinGW,
+Cygwin, or MSYS is the host or build platform, while the other platform
+is a Unix-style system.  In these cases, there are often conflicts
+between the format of the file names and paths expected within host
+platform libraries and executables, and those employed on the build
+platform.
+
+   This situation is best described using a concrete example: suppose
+the build platform is GNU/Linux with canonical triplet
+`i686-pc-linux-gnu'.  Suppose further that the host platform is MinGW
+with canonical triplet `i586-pc-mingw32'.  On the GNU/Linux platform
+there is a cross compiler following the usual naming conventions of
+such compilers, where the compiler name is prefixed by the host
+canonical triplet (or suitable alias).  (For more information
+concerning canonical triplets and platform aliases, see *note
+Specifying Target Triplets: (autoconf)Specifying Target Triplets. and
+*note Canonicalizing: (autoconf)Canonicalizing.)  In this case, the C
+compiler is named `i586-pc-mingw32-gcc'.
+
+   As described in *note Wrapper executables::, for the MinGW host
+platform libtool uses a wrapper executable to set various environment
+variables before launching the actual program executable.  Like the
+program executable, the wrapper executable is cross-compiled for the
+host platform (that is, for MinGW).  As described above, ordinarily a
+host platform executable cannot be executed on the build platform, but
+in this case the Wine environment could be used to launch the MinGW
+application from GNU/Linux.  However, the wrapper executable, as a host
+platform (MinGW) application, must set the `PATH' variable so that the
+true application's dependent libraries can be located--but the contents
+of the `PATH' variable must be structured for MinGW.  Libtool must use
+the Wine file name mapping facilities to determine the correct value so
+that the wrapper executable can set the `PATH' variable to point to the
+correct location.
+
+   For example, suppose we are compiling an application in `/var/tmp' on
+GNU/Linux, using separate source code and build directories:
+
+     `/var/tmp/foo-1.2.3/app/'          (application source code)
+     `/var/tmp/foo-1.2.3/lib/'          (library source code)
+     `/var/tmp/BUILD/app/'              (application build objects here)
+     `/var/tmp/BUILD/lib/'              (library build objects here)
+
+   Since the library will be built in `/var/tmp/BUILD/lib', the wrapper
+executable (which will be in `/var/tmp/BUILD/app') must add that
+directory to `PATH' (actually, it must add the directory named OBJDIR
+under `/var/tmp/BUILD/lib', but we'll ignore that detail for now).
+However, Windows does not have a concept of Unix-style file or
+directory names such as `/var/tmp/BUILD/lib'.  Therefore, Wine provides
+a mapping from Windows file names such as `C:\Program Files' to specific
+Unix-style file names.  Wine also provides a utility that can be used
+to map Unix-style file names to Windows file names.
+
+   In this case, the wrapper executable should actually add the value
+
+     Z:\var\tmp\BUILD\lib
+
+to the `PATH'.  libtool contains support for path conversions of this
+type, for a certain limited set of build and host platform
+combinations. In this case, libtool will invoke Wine's `winepath'
+utility to ensure that the correct `PATH' value is used.  For more
+information, see *note File name conversion::.
+
+
+File: libtool.info,  Node: File name conversion,  Next: Windows DLLs,  Prev: Cross compiling,  Up: Platform quirks
+
+15.3.7 File name conversion
+---------------------------
+
+In certain situations, libtool must convert file names and paths between
+formats appropriate to different platforms.  Usually this occurs when
+cross-compiling, and affects only the ability to launch host platform
+executables on the build platform using an emulation or API-enhancement
+environment such as Wine.  Failure to convert paths (*note File Name
+Conversion Failure::) will cause a warning to be issued, but rarely
+causes the build to fail--and should have no affect on the compiled
+products, once installed properly on the host platform.  For more
+information, *note Cross compiling::.
+
+   However, file name conversion may also occur in another scenario:
+when using a Unix emulation system on Windows (such as Cygwin or MSYS),
+combined with a native Windows compiler such as MinGW or MSVC.  Only a
+limited set of such scenarios are currently supported; in other cases
+file name conversion is skipped.  The lack of file name conversion
+usually means that uninstalled executables can't be launched, but only
+rarely causes the build to fail (*note File Name Conversion Failure::).
+
+   libtool supports file name conversion in the following scenarios:

+15.3.7.1 File Name Conversion Failure
+.....................................
+
+In most cases, file name conversion is not needed or attempted.
+However, when libtool detects that a specific combination of build and
+host platform does require file name conversion, it is possible that
+the conversion may fail.  In these cases, you may see a warning such as
+the following:
+
+     Could not determine the host file name corresponding to
+       `... a file name ...'
+     Continuing, but uninstalled executables may not work.
+
+or
+
+     Could not determine the host path corresponding to
+       `... a path ...'
+     Continuing, but uninstalled executables may not work.
+
+This should not cause the build to fail.  At worst, it means that the
+wrapper executable will specify file names or paths appropriate for the
+build platform.  Since those are not appropriate for the host platform,
+the uninstalled executables would not operate correctly, even when the
+wrapper executable is launched via the appropriate emulation or
+API-enhancement (e.g. Wine).  Simply install the executables on the
+host platform, and execute them there.

+15.3.7.2 Native MinGW File Name Conversion
+..........................................
+
+MSYS is a Unix emulation environment for Windows, and is specifically
+designed such that in normal usage it _pretends_ to be MinGW or native
+Windows, but understands Unix-style file names and paths, and supports
+standard Unix tools and shells.  Thus, "native" MinGW builds are
+actually an odd sort of cross-compile, from an MSYS Unix emulation
+environment "pretending" to be MinGW, to actual native Windows.
+
+   When an MSYS shell launches a native Windows executable (as opposed
+to other _MSYS_ executables), it uses a system of heuristics to detect
+any command-line arguments that contain file names or paths.  It
+automatically converts these file names from the MSYS (Unix-like)
+format, to the corresponding Windows file name, before launching the
+executable.  However, this auto-conversion facility is only available
+when using the MSYS runtime library.  The wrapper executable itself is
+a MinGW application (that is, it does not use the MSYS runtime
+library).  The wrapper executable must set `PATH' to, and call
+`_spawnv' with, values that have already been converted from MSYS
+format to Windows.  Thus, when libtool writes the source code for the
+wrapper executable, it must manually convert MSYS paths to Windows
+format, so that the Windows values can be hard-coded into the wrapper
+executable.

+15.3.7.3 Cygwin/Windows File Name Conversion
+............................................
+
+Cygwin provides a Unix emulation environment for Windows.  As part of
+that emulation, it provides a file system mapping that presents the
+Windows file system in a Unix-compatible manner.  Cygwin also provides
+a utility `cygpath' that can be used to convert file names and paths
+between the two representations.  In a correctly configured Cygwin

+
+   Libtool uses `cygpath' to convert from Cygwin (Unix-style) file names
+and paths to Windows format when the build platform is Cygwin and the
+host platform is MinGW.
+
+   When the host platform is Cygwin, but the build platform is MSYS or
+some Unix system, libtool also uses `cygpath' to convert from Windows
+to Cygwin format (after first converting from the build platform format
+to Windows format; see *note Native MinGW File Name Conversion:: and
+*note Unix/Windows File Name Conversion::).  Because the build platform
+is not Cygwin, `cygpath' is not (and should not be) in the `PATH'.
+Therefore, in this configuration the environment variable `LT_CYGPATH'
+is required. *Note LT_CYGPATH::.

+Wine (http://www.winehq.org/) provides an interpretation environment for
+some Unix platforms in which Windows applications can be executed.  It
+provides a mapping between the Unix file system and a virtual Windows
+file system used by the Windows programs.  For the file name conversion
+to work, Wine must be installed and properly configured on the build
+platform, and the `winepath' application must be in the build
+platform's `PATH'.  In addition, on 32bit GNU/Linux it is usually
+helpful if the binfmt extension is enabled.

+
+15.3.7.5 LT_CYGPATH
+...................
+
+For some cross-compile configurations (where the host platform is
+Cygwin), the `cygpath' program is used to convert file names from the
+build platform notation to the Cygwin form (technically, this
+conversion is from Windows notation to Cygwin notation; the conversion
+from the build platform format to Windows notation is performed via
+other means).  However, because the `cygpath' program is not (and
+should not be) in the `PATH' on the build platform, `LT_CYGPATH' must
+specify the full build platform file name (that is, the full Unix or
+MSYS file name) of the `cygpath' program.
+
+   The reason `cygpath' should not be in the build platform `PATH' is
+twofold: first, `cygpath' is usually installed in the same directory as
+many other Cygwin executables, such as `sed', `cp', etc.  If the build
+platform environment had this directory in its `PATH', then these
+Cygwin versions of common Unix utilities might be used in preference to
+the ones provided by the build platform itself, with deleterious
+effects.  Second, especially when Cygwin-1.7 or later is used, multiple
+Cygwin installations can coexist within the same Windows instance.
+Each installation will have separate "mount tables" specified in
+`CYGROOT-N/etc/fstab'.  These "mount tables" control how that instance
+of Cygwin will map Windows file names and paths to Cygwin form.  Each
+installation's `cygpath' utility automatically deduces the appropriate
+`/etc/fstab' file.  Since each `CYGROOT-N/etc/fstab' mount table may
+specify different mappings, it matters which `cygpath' is used.
+
+   Note that `cygpath' is a Cygwin application; to execute this tool
+from Unix requires a working and properly configured Wine installation,
+as well as enabling the GNU/Linux `binfmt' extension.  Furthermore, the
+Cygwin `setup.exe' tool should have been used, via Wine, to properly
+install Cygwin into the Wine file system (and registry).
+
+   Unfortunately, Wine support for Cygwin is intermittent.  Recent
+releases of Cygwin (1.7 and above) appear to require more Windows API
+support than Wine provides (as of Wine version 1.2); most Cygwin
+applications fail to execute.  This includes `cygpath' itself.  Hence,
+it is best _not_ to use the LT_CYGPATH machinery in libtool when
+performing Unix to Cygwin cross-compiles.  Similarly, it is best _not_
+to enable the GNU/Linux binfmt support in this configuration, because
+while Wine will fail to execute the compiled Cygwin applications, it
+will still exit with status zero.  This tends to confuse build systems
+and test suites (including libtool's own testsuite, resulting in
+spurious reported failures).  Wine support for the older Cygwin-1.5
+series appears satisfactory, but the Cygwin team no longer supports
+Cygwin-1.5.  It is hoped that Wine will eventually be improved such that
+Cygwin-1.7 will again operate correctly under Wine.  Until then,
+libtool will report warnings as described in *note File Name Conversion
+Failure:: in these scenarios.
+
+   However, `LT_CYGPATH' is also used for the MSYS to Cygwin cross
+compile scenario, and operates as expected.

+File: libtool.info,  Node: Cygwin to MinGW Cross,  Prev: LT_CYGPATH,  Up: File name conversion
+
+15.3.7.6 Cygwin to MinGW Cross
+..............................
+
+There are actually three different scenarios that could all
+legitimately be called a "Cygwin to MinGW" cross compile.  The current
+(and standard) definition is when there is a compiler that produces
+native Windows libraries and applications, but which itself is a Cygwin
+application, just as would be expected in any other cross compile setup.
+
+   However, historically there were two other definitions, which we
+will refer to as the _fake_ one, and the _lying_ one.
+
+   In the _fake_ Cygwin to MinGW cross compile case, you actually use a
+native MinGW compiler, but you do so from within a Cygwin environment:
+
+     export PATH="/c/MinGW/bin:${PATH}"
+     configure --build=i686-pc-cygwin \
+     	--host=mingw32 \
+     	NM=/c/MinGW/bin/nm.exe
+
+   In this way, the build system "knows" that you are cross compiling,
+and the file name conversion logic will be used.  However, because the
+tools (`mingw32-gcc', `nm', `ar') used are actually native Windows
+applications, they will not understand any Cygwin (that is, Unix-like)
+absolute file names passed as command line arguments (and, unlike MSYS,
+Cygwin does not automatically convert such arguments).  However, so
+long as only relative file names are used in the build system, and
+non-Windows-supported Unix idioms such as symlinks and mount points are
+avoided, this scenario should work.
+
+   If you must use absolute file names, you will have to force Libtool
+to convert file names for the toolchain in this case, by doing the
+following before you run configure:
+
+     export lt_cv_to_tool_file_cmd=func_convert_file_cygwin_to_w32
+   
+   In the _lying_ Cygwin to MinGW cross compile case, you lie to the
+build system:
+
+     export PATH="/c/MinGW/bin:${PATH}"
+     configure --build=i686-pc-mingw32 \
+     	--host=i686-pc-mingw32 \
+     	--disable-dependency-tracking
+
+and claim that the build platform is MinGW, even though you are actually
+running under _Cygwin_ and not MinGW.  In this case, libtool does _not_
+know that you are performing a cross compile, and thinks instead that
+you are performing a native MinGW build.  However, as described in
+(*note Native MinGW File Name Conversion::), that scenario triggers an
+"MSYS to Windows" file name conversion.  This, of course, is the wrong
+conversion since we are actually running under Cygwin.  Also, the
+toolchain is expecting Windows file names (not Cygwin) but unless told
+so Libtool will feed Cygwin file names to the toolchain in this case.
+To force the correct file name conversions in this situation, you
+should do the following _before_ running configure:
+
+     export lt_cv_to_host_file_cmd=func_convert_file_cygwin_to_w32
+     export lt_cv_to_tool_file_cmd=func_convert_file_cygwin_to_w32
+   
+   Note that this relies on internal implementation details of libtool,
+and is subject to change.  Also, `--disable-dependency-tracking' is
+required, because otherwise the MinGW GCC will generate dependency
+files that contain Windows file names.  This, in turn, will confuse the
+Cygwin `make' program, which does not accept Windows file names:
+
+     Makefile:1: *** target pattern contains no `%'.  Stop.
+
+   There have also always been a number of other details required for
+the _lying_ case to operate correctly, such as the use of so-called
+"identity mounts":
+
+     # CYGWIN-ROOT/etc/fstab
+     D:/foo    /foo     some_fs binary 0 0
+     D:/bar    /bar     some_fs binary 0 0
+     E:/grill  /grill   some_fs binary 0 0
+
+   In this way, top-level directories of each drive are available using
+identical names within Cygwin.
+
+   Note that you also need to ensure that the standard Unix directories
+(like `/bin', `/lib', `/usr', `/etc') appear in the root of a drive.
+This means that you must install Cygwin itself into the `C:/' root
+directory (or `D:/', or `E:/', etc)--instead of the recommended
+installation into `C:/cygwin/'.  In addition, all file names used in
+the build system must be relative, symlinks should not be used within
+the source or build directory trees, and all `-M*' options to `gcc'
+except `-MMD' must be avoided.
+
+   This is quite a fragile setup, but it has been in historical use,
+and so is documented here.

+
+15.3.8 Windows DLLs
+-------------------
+
+This topic describes a couple of ways to portably create Windows Dynamic
+Link Libraries (DLLs).  Libtool knows how to create DLLs using GNU tools
+and using Microsoft tools.
+
+   A typical library has a "hidden" implementation with an interface
+described in a header file.  On just about every system, the interface
+could be something like this:
+
+   Example `foo.h':
+
+     #ifndef FOO_H
+     #define FOO_H
+
+     int one (void);
+     int two (void);
+     extern int three;
+
+     #endif /* FOO_H */
+
+And the implementation could be something like this:
+
+   Example `foo.c':
+
+     #include "foo.h"
+
+     int one (void)
+     {
+       return 1;
+     }
+
+     int two (void)
+     {
+       return three - one ();
+     }
+
+     int three = 3;
+
+   When using contemporary GNU tools to create the Windows DLL, the
+above code will work there too, thanks to its auto-import/auto-export
+features.  But that is not the case when using older GNU tools or
+perhaps more interestingly when using proprietary tools.  In those
+cases the code will need additional decorations on the interface
+symbols with `__declspec(dllimport)' and `__declspec(dllexport)'
+depending on whether the library is built or it's consumed and how it's
+built and consumed.  However, it should be noted that it would have
+worked also with Microsoft tools, if only the variable `three' hadn't
+been there, due to the fact the Microsoft tools will automatically
+import functions (but sadly not variables) and Libtool will
+automatically export non-static symbols as described next.
+
+   With Microsoft tools, Libtool digs through the object files that
+make up the library, looking for non-static symbols to automatically
+export.  I.e., Libtool with Microsoft tools tries to mimic the
+auto-export feature of contemporary GNU tools.  It should be noted that
+the GNU auto-export feature is turned off when an explicit
+`__declspec(dllexport)' is seen.  The GNU tools do this to not make
+more symbols visible for projects that have already taken the trouble
+to decorate symbols.  There is no similar way to limit which symbols
+are visible in the code when Libtool is using Microsoft tools.  In
+order to limit symbol visibility in that case you need to use one of
+the options `-export-symbols' or `-export-symbols-regex'.
+
+   No matching help with auto-import is provided by Libtool, which is
+why variables must be decorated to import them from a DLL for
+everything but contemporary GNU tools.  As stated above, functions are
+automatically imported by both contemporary GNU tools and Microsoft
+tools, but for other proprietary tools the auto-import status of
+functions is unknown.
+
+   When the objects that form the library are built, there are generally
+two copies built for each object.  One copy is used when linking the DLL
+and one copy is used for the static library.  On Windows systems, a pair
+of defines are commonly used to discriminate how the interface symbols
+should be decorated.  The first define is `-DDLL_EXPORT' which is
+automatically provided by Libtool when `libtool' builds the copy of the
+object that is destined for the DLL.  The second define is
+`-DLIBFOO_BUILD' (or similar) which is often added by the package
+providing the library and is used when building the library, but not
+when consuming the library.
+
+   However, the matching double compile is not performed when consuming
+libraries.  It is therefore not possible to reliably distinguish if the
+consumer is importing from a DLL or if it is going to use a static
+library.
+
+   With contemporary GNU tools, auto-import often saves the day, but see
+the GNU ld documentation and its `--enable-auto-import' option for some
+corner cases when it does not (*note `--enable-auto-import':
+(ld)Options.).
+
+   With Microsoft tools you typically get away with always compiling the
+code such that variables are expected to be imported from a DLL and
+functions are expected to be found in a static library.  The tools will
+then automatically import the function from a DLL if that is where they
+are found.  If the variables are not imported from a DLL as expected,
+but are found in a static library that is otherwise pulled in by some
+function, the linker will issue a warning (LNK4217) that a locally
+defined symbol is imported, but it still works.  In other words, this
+scheme will not work to only consume variables from a library.  There is
+also a price connected to this liberal use of imports in that an extra
+indirection is introduced when you are consuming the static version of
+the library.  That extra indirection is unavoidable when the DLL is
+consumed, but it is not needed when consuming the static library.
+
+   For older GNU tools and other proprietary tools there is no generic
+way to make it possible to consume either of the DLL or the static
+library without user intervention, the tools need to be told what is
+intended.  One common assumption is that if a DLL is being built
+(`DLL_EXPORT' is defined) then that DLL is going to consume any
+dependent libraries as DLLs.  If that assumption is made everywhere, it
+is possible to select how an end-user application is consuming
+libraries by adding a single flag `-DDLL_EXPORT' when a DLL build is
+required.  This is of course an all or nothing deal, either everything
+as DLLs or everything as static libraries.
+
+   To sum up the above, the header file of the foo library needs to be
+changed into something like this:
+
+   Modified `foo.h':
+
+     #ifndef FOO_H
+     #define FOO_H
+
+     #if defined _WIN32 && !defined __GNUC__
+     # ifdef LIBFOO_BUILD
+     #  ifdef DLL_EXPORT
+     #   define LIBFOO_SCOPE            __declspec (dllexport)
+     #   define LIBFOO_SCOPE_VAR extern __declspec (dllexport)
+     #  endif
+     # elif defined _MSC_VER
+     #  define LIBFOO_SCOPE
+     #  define LIBFOO_SCOPE_VAR  extern __declspec (dllimport)
+     # elif defined DLL_EXPORT
+     #  define LIBFOO_SCOPE             __declspec (dllimport)
+     #  define LIBFOO_SCOPE_VAR  extern __declspec (dllimport)
+     # endif
+     #endif
+     #ifndef LIBFOO_SCOPE
+     # define LIBFOO_SCOPE
+     # define LIBFOO_SCOPE_VAR extern
+     #endif
+
+     LIBFOO_SCOPE     int one (void);
+     LIBFOO_SCOPE     int two (void);
+     LIBFOO_SCOPE_VAR int three;
+
+     #endif /* FOO_H */
+
+   When the targets are limited to contemporary GNU tools and Microsoft
+tools, the above can be simplified to the following:
+
+   Simplified `foo.h':
+
+     #ifndef FOO_H
+     #define FOO_H
+
+     #if defined _WIN32 && !defined __GNUC__ && !defined LIBFOO_BUILD
+     # define LIBFOO_SCOPE_VAR extern __declspec (dllimport)
+     #else
+     # define LIBFOO_SCOPE_VAR extern
+     #endif
+
+     int one (void);
+     int two (void);
+     LIBFOO_SCOPE_VAR int three;
+
+     #endif /* FOO_H */
+
+   This last simplified version can of course only work when Libtool is
+used to build the DLL, as no symbols would be exported otherwise (i.e.,
+when using Microsoft tools).
+
+   It should be noted that there are various projects that attempt to
+relax these requirements by various low level tricks, but they are not
+discussed here.  Examples are FlexDLL
+(http://alain.frisch.fr/flexdll.html) and edll
+(http://edll.sourceforge.net/).

+File: libtool.info,  Node: libtool script contents,  Next: Cheap tricks,  Prev: Platform quirks,  Up: Maintaining
+
+15.4 `libtool' script contents
+==============================
+
+Since version 1.4, the `libtool' script is generated by `configure'
+(*note Configuring::).  In earlier versions, `configure' achieved this
+by calling a helper script called `ltconfig'.  From libtool version 0.7
+to 1.0, this script simply set shell variables, then sourced the
+libtool backend, `ltmain.sh'.  `ltconfig' from libtool version 1.1
+through 1.3 inlined the contents of `ltmain.sh' into the generated
+`libtool', which improved performance on many systems.  The tests that
+`ltconfig' used to perform are now kept in `libtool.m4' where they can
+be written using Autoconf.  This has the runtime performance benefits
+of inlined `ltmain.sh', _and_ improves the build time a little while
+considerably easing the amount of raw shell code that used to need
+maintaining.
+
+   The convention used for naming variables that hold shell commands for
+delayed evaluation, is to use the suffix `_cmd' where a single line of
+valid shell script is needed, and the suffix `_cmds' where multiple
+lines of shell script *may* be delayed for later evaluation.  By
+convention, `_cmds' variables delimit the evaluation units with the `~'
+character where necessary.
+
+   Here is a listing of each of the configuration variables, and how
+they are used within `ltmain.sh' (*note Configuring::):
+
+ -- Variable: AR
+     The name of the system library archiver.
+
+ -- Variable: CC
+     The name of the compiler used to configure libtool.  This will
+     always contain the compiler for the current language (*note
+     Tags::).
+
+ -- Variable: ECHO
+     An `echo' program that does not interpret backslashes as an escape
+     character.  It may be given only one argument, so due quoting is
+     necessary.
+
+ -- Variable: LD
+     The name of the linker that libtool should use internally for
+     reloadable linking and possibly shared libraries.
+
+ -- Variable: LTCC
+ -- Variable: LTCFLAGS
+     The name of the C compiler and C compiler flags used to configure
+     libtool.
+
+ -- Variable: NM
+     The name of a BSD- or MS-compatible program that produces listings
+     of global symbols.  For BSD `nm', the symbols should be in one the
+     following formats:
+
+          ADDRESS C GLOBAL-VARIABLE-NAME
+          ADDRESS D GLOBAL-VARIABLE-NAME
+          ADDRESS T GLOBAL-FUNCTION-NAME
+
+     For MS `dumpbin', the symbols should be in one of the following
+     formats:
+
+          COUNTER SIZE    UNDEF    notype       External     | GLOBAL-VAR
+          COUNTER ADDRESS SECTION  notype       External     | GLOBAL-VAR
+          COUNTER ADDRESS SECTION  notype ()    External     | GLOBAL-FUNC
+
+     The SIZE of the global variables are not zero and the SECTION of
+     the global functions are not "UNDEF". Symbols in "pick any"
+     sections ("pick any" appears in the section header) are not global
+     either.
+
+ -- Variable: RANLIB
+     Set to the name of the `ranlib' program, if any.
+
+ -- Variable: allow_undefined_flag
+     The flag that is used by `archive_cmds' in order to declare that
+     there will be unresolved symbols in the resulting shared library.
+     Empty, if no such flag is required.  Set to `unsupported' if there
+     is no way to generate a shared library with references to symbols
+     that aren't defined in that library.
+
+ -- Variable: always_export_symbols
+     Whether libtool should automatically generate a list of exported
+     symbols using `export_symbols_cmds' before linking an archive.
+     Set to `yes' or `no'.  Default is `no'.
+
+ -- Variable: archive_cmds
+ -- Variable: archive_expsym_cmds
+ -- Variable: old_archive_cmds
+     Commands used to create shared libraries, shared libraries with
+     `-export-symbols' and static libraries, respectively.
+
+ -- Variable: archiver_list_spec
+     Specify filename containing input files for `AR'.
+
+ -- Variable: old_archive_from_new_cmds
+     If the shared library depends on a static library,
+     `old_archive_from_new_cmds' contains the commands used to create
+     that static library.  If this variable is not empty,
+     `old_archive_cmds' is not used.
+
+ -- Variable: old_archive_from_expsyms_cmds
+     If a static library must be created from the export symbol list in
+     order to correctly link with a shared library,
+     `old_archive_from_expsyms_cmds' contains the commands needed to
+     create that static library.  When these commands are executed, the
+     variable `soname' contains the name of the shared library in
+     question, and the `$objdir/$newlib' contains the path of the
+     static library these commands should build.  After executing these
+     commands, libtool will proceed to link against `$objdir/$newlib'
+     instead of `soname'.
+
+ -- Variable: lock_old_archive_extraction
+     Set to `yes' if the extraction of a static library requires locking
+     the library file.  This is required on Darwin.
+
+ -- Variable: build
+ -- Variable: build_alias
+ -- Variable: build_os
+     Set to the specified and canonical names of the system that
+     libtool was built on.
+
+ -- Variable: build_libtool_libs
+     Whether libtool should build shared libraries on this system.  Set
+     to `yes' or `no'.
+
+ -- Variable: build_old_libs
+     Whether libtool should build static libraries on this system.  Set
+     to `yes' or `no'.
+
+ -- Variable: compiler_c_o
+     Whether the compiler supports the `-c' and `-o' options
+     simultaneously.  Set to `yes' or `no'.
+
+ -- Variable: compiler_needs_object
+     Whether the compiler has to see an object listed on the command
+     line in order to successfully invoke the linker.  If `no', then a
+     set of convenience archives or a set of object file names can be
+     passed via linker-specific options or linker scripts.
+
+ -- Variable: dlopen_support
+     Whether `dlopen' is supported on the platform.  Set to `yes' or
+     `no'.
+
+ -- Variable: dlopen_self
+     Whether it is possible to `dlopen' the executable itself.  Set to
+     `yes' or `no'.
+
+ -- Variable: dlopen_self_static
+     Whether it is possible to `dlopen' the executable itself, when it
+     is linked statically (`-all-static').  Set to `yes' or `no'.
+
+ -- Variable: exclude_expsyms
+     List of symbols that should not be listed in the preloaded symbols.
+
+ -- Variable: export_dynamic_flag_spec
+     Compiler link flag that allows a dlopened shared library to
+     reference symbols that are defined in the program.
+
+ -- Variable: export_symbols_cmds
+     Commands to extract exported symbols from `libobjs' to the file
+     `export_symbols'.
+
+ -- Variable: extract_expsyms_cmds
+     Commands to extract the exported symbols list from a shared
+     library.  These commands are executed if there is no file
+     `$objdir/$soname-def', and should write the names of the exported
+     symbols to that file, for the use of
+     `old_archive_from_expsyms_cmds'.
+
+ -- Variable: fast_install
+     Determines whether libtool will privilege the installer or the
+     developer.  The assumption is that installers will seldom run
+     programs in the build tree, and the developer will seldom install.
+     This is only meaningful on platforms where
+     `shlibpath_overrides_runpath' is not `yes', so `fast_install' will
+     be set to `needless' in this case.  If `fast_install' set to
+     `yes', libtool will create programs that search for installed
+     libraries, and, if a program is run in the build tree, a new copy
+     will be linked on-demand to use the yet-to-be-installed libraries.
+     If set to `no', libtool will create programs that use the
+     yet-to-be-installed libraries, and will link a new copy of the
+     program at install time.  The default value is `yes' or
+     `needless', depending on platform and configuration flags, and it
+     can be turned from `yes' to `no' with the configure flag
+     `--disable-fast-install'.
+
+     On some systems, the linker always hardcodes paths to dependent
+     libraries into the output.  In this case, `fast_install' is never
+     set to `yes', and relinking at install time is triggered.  This
+     also means that `DESTDIR' installation does not work as expected.
+
+ -- Variable: file_magic_glob
+     How to find potential files when `deplibs_check_method' is
+     `file_magic'. `file_magic_glob' is a `sed' expression, and the
+     `sed' instance is fed potential file names that are transformed by
+     the `file_magic_glob' expression. Useful when the shell does not
+     support the shell option `nocaseglob', making `want_nocaseglob'
+     inappropriate. Normally disabled (i.e.  `file_magic_glob' is
+     empty).
+
+ -- Variable: finish_cmds
+     Commands to tell the dynamic linker how to find shared libraries
+     in a specific directory.
+
+ -- Variable: finish_eval
+     Same as `finish_cmds', except the commands are not displayed.
+
+ -- Variable: global_symbol_pipe
+     A pipeline that takes the output of `NM', and produces a listing of
+     raw symbols followed by their C names.  For example:
+
+          $ eval "$NM progname | $global_symbol_pipe"
+          D SYMBOL1 C-SYMBOL1
+          T SYMBOL2 C-SYMBOL2
+          C SYMBOL3 C-SYMBOL3
+          ...
+          $
+
+     The first column contains the symbol type (used to tell data from
+     code) but its meaning is system dependent.
+
+ -- Variable: global_symbol_to_cdecl
+     A pipeline that translates the output of `global_symbol_pipe' into
+     proper C declarations.  Since some platforms, such as HP/UX, have
+     linkers that differentiate code from data, data symbols are
+     declared as data, and code symbols are declared as functions.
+
+ -- Variable: hardcode_action
+     Either `immediate' or `relink', depending on whether shared
+     library paths can be hardcoded into executables before they are
+     installed, or if they need to be relinked.
+
+ -- Variable: hardcode_direct
+     Set to `yes' or `no', depending on whether the linker hardcodes
+     directories if a library is directly specified on the command line
+     (such as `DIR/libNAME.a') when `hardcode_libdir_flag_spec' is
+     specified.
+
+ -- Variable: hardcode_direct_absolute
+     Some architectures hardcode "absolute" library directories that
+     can not be overridden by `shlibpath_var' when `hardcode_direct' is
+     `yes'.  In that case set `hardcode_direct_absolute' to `yes', or
+     otherwise `no'.
+
+ -- Variable: hardcode_into_libs
+     Whether the platform supports hardcoding of run-paths into
+     libraries.  If enabled, linking of programs will be much simpler
+     but libraries will need to be relinked during installation.  Set
+     to `yes' or `no'.
+
+ -- Variable: hardcode_libdir_flag_spec
+     Flag to hardcode a `libdir' variable into a binary, so that the
+     dynamic linker searches `libdir' for shared libraries at runtime.
+     If it is empty, libtool will try to use some other hardcoding
+     mechanism.
+
+ -- Variable: hardcode_libdir_separator
+     If the compiler only accepts a single `hardcode_libdir_flag', then
+     this variable contains the string that should separate multiple
+     arguments to that flag.
+
+ -- Variable: hardcode_minus_L
+     Set to `yes' or `no', depending on whether the linker hardcodes
+     directories specified by `-L' flags into the resulting executable
+     when `hardcode_libdir_flag_spec' is specified.
+
+ -- Variable: hardcode_shlibpath_var
+     Set to `yes' or `no', depending on whether the linker hardcodes
+     directories by writing the contents of `$shlibpath_var' into the
+     resulting executable when `hardcode_libdir_flag_spec' is
+     specified.  Set to `unsupported' if directories specified by
+     `$shlibpath_var' are searched at run time, but not at link time.
+
+ -- Variable: host
+ -- Variable: host_alias
+ -- Variable: host_os
+     Set to the specified and canonical names of the system that
+     libtool was configured for.
+
+ -- Variable: include_expsyms
+     List of symbols that must always be exported when using
+     `export_symbols'.
+
+ -- Variable: inherit_rpath
+     Whether the linker adds runtime paths of dependency libraries to
+     the runtime path list, requiring libtool to relink the output when
+     installing.  Set to `yes' or `no'.  Default is `no'.
+
+ -- Variable: install_override_mode
+     Permission mode override for installation of shared libraries.  If
+     the runtime linker fails to load libraries with wrong permissions,
+     then it may fail to execute programs that are needed during
+     installation, because these need the library that has just been
+     installed.  In this case, it is necessary to pass the mode to
+     `install' with `-m INSTALL_OVERRIDE_MODE'.
+
+ -- Variable: libext
+     The standard old archive suffix (normally `a').
+
+ -- Variable: libname_spec
+     The format of a library name prefix.  On all Unix systems, static
+     libraries are called `libNAME.a', but on some systems (such as
+     OS/2 or MS-DOS), the library is just called `NAME.a'.
+
+ -- Variable: library_names_spec
+     A list of shared library names.  The first is the name of the file,
+     the rest are symbolic links to the file.  The name in the list is
+     the file name that the linker finds when given `-lNAME'.
+
+ -- Variable: link_all_deplibs
+     Whether libtool must link a program against all its dependency
+     libraries.  Set to `yes' or `no'.  Default is `unknown', which is
+     a synonym for `yes'.
+
+ -- Variable: link_static_flag
+     Linker flag (passed through the C compiler) used to prevent dynamic
+     linking.
+
+ -- Variable: macro_version
+ -- Variable: macro_revision
+     The release and revision from which the libtool.m4 macros were
+     taken.  This is used to ensure that macros and `ltmain.sh'
+     correspond to the same Libtool version.
+
+ -- Variable: max_cmd_len
+     The approximate longest command line that can be passed to `$SHELL'
+     without being truncated, as computed by `LT_CMD_MAX_LEN'.
+
+ -- Variable: need_lib_prefix
+     Whether we can `dlopen' modules without a `lib' prefix.  Set to
+     `yes' or `no'.  By default, it is `unknown', which means the same
+     as `yes', but documents that we are not really sure about it.
+     `no' means that it is possible to `dlopen' a module without the
+     `lib' prefix.
+
+ -- Variable: need_version
+     Whether versioning is required for libraries, i.e. whether the
+     dynamic linker requires a version suffix for all libraries.  Set
+     to `yes' or `no'.  By default, it is `unknown', which means the
+     same as `yes', but documents that we are not really sure about it.
+
+ -- Variable: need_locks
+     Whether files must be locked to prevent conflicts when compiling
+     simultaneously.  Set to `yes' or `no'.
+
+ -- Variable: nm_file_list_spec
+     Specify filename containing input files for `NM'.
+
+ -- Variable: no_builtin_flag
+     Compiler flag to disable builtin functions that conflict with
+     declaring external global symbols as `char'.
+
+ -- Variable: no_undefined_flag
+     The flag that is used by `archive_cmds' in order to declare that
+     there will be no unresolved symbols in the resulting shared
+     library.  Empty, if no such flag is required.
+
+ -- Variable: objdir
+     The name of the directory that contains temporary libtool files.
+
+ -- Variable: objext
+     The standard object file suffix (normally `o').
+
+ -- Variable: pic_flag
+     Any additional compiler flags for building library object files.
+
+ -- Variable: postinstall_cmds
+ -- Variable: old_postinstall_cmds
+     Commands run after installing a shared or static library,
+     respectively.
+
+ -- Variable: postuninstall_cmds
+ -- Variable: old_postuninstall_cmds
+     Commands run after uninstalling a shared or static library,
+     respectively.
+
+ -- Variable: postlink_cmds
+     Commands necessary for finishing linking programs. `postlink_cmds'
+     are executed immediately after the program is linked.  Any
+     occurrence of the string `@OUTPUT@' in `postlink_cmds' is replaced
+     by the name of the created executable (i.e. not the wrapper, if a
+     wrapper is generated) prior to execution.  Similarly,
+     `@TOOL_OUTPUT@' is replaced by the toolchain format of `@OUTPUT@'.
+     Normally disabled (i.e. `postlink_cmds' empty).
+
+ -- Variable: reload_cmds
+ -- Variable: reload_flag
+     Commands to create a reloadable object.  Set `reload_cmds' to
+     `false' on systems that cannot create reloadable objects.
+
+ -- Variable: runpath_var
+     The environment variable that tells the linker which directories to
+     hardcode in the resulting executable.
+
+ -- Variable: shlibpath_overrides_runpath
+     Indicates whether it is possible to override the hard-coded library
+     search path of a program with an environment variable.  If this is
+     set to no, libtool may have to create two copies of a program in
+     the build tree, one to be installed and one to be run in the build
+     tree only.  When each of these copies is created depends on the
+     value of `fast_install'.  The default value is `unknown', which is
+     equivalent to `no'.
+
+ -- Variable: shlibpath_var
+     The environment variable that tells the dynamic linker where to
+     find shared libraries.
+
+ -- Variable: soname_spec
+     The name coded into shared libraries, if different from the real
+     name of the file.
+
+ -- Variable: striplib
+ -- Variable: old_striplib
+     Command to strip a shared (`striplib') or static (`old_striplib')
+     library, respectively.  If these variables are empty, the strip
+     flag in the install mode will be ignored for libraries (*note
+     Install mode::).
+
+ -- Variable: sys_lib_dlsearch_path_spec
+     Expression to get the run-time system library search path.
+     Directories that appear in this list are never hard-coded into
+     executables.
+
+ -- Variable: sys_lib_search_path_spec
+     Expression to get the compile-time system library search path.
+     This variable is used by libtool when it has to test whether a
+     certain library is shared or static.  The directories listed in
+     `shlibpath_var' are automatically appended to this list, every time
+     libtool runs (i.e., not at configuration time), because some
+     linkers use this variable to extend the library search path.
+     Linker switches such as `-L' also augment the search path.
+
+ -- Variable: thread_safe_flag_spec
+     Linker flag (passed through the C compiler) used to generate
+     thread-safe libraries.
+
+ -- Variable: to_host_file_cmd
+     If the toolchain is not native to the build platform (e.g. if you
+     are using MSYS to drive the scripting, but are using the MinGW
+     native Windows compiler) this variable describes how to convert
+     file names from the format used by the build platform to the
+     format used by host platform.  Normally set to
+     `func_convert_file_noop', libtool will autodetect most cases in
+     which other values should be used.  On rare occasions, it may be
+     necessary to override the autodetected value (*note Cygwin to
+     MinGW Cross::).
+
+ -- Variable: to_tool_file_cmd
+     If the toolchain is not native to the build platform (e.g. if you
+     are using some Unix to drive the scripting together with a Windows
+     toolchain running in Wine) this variable describes how to convert
+     file names from the format used by the build platform to the
+     format used by the toolchain.  Normally set to
+     `func_convert_file_noop'.
+
+ -- Variable: version_type
+     The library version numbering type.  One of `libtool',
+     `freebsd-aout', `freebsd-elf', `irix', `linux', `osf', `sunos',
+     `windows', or `none'.
+
+ -- Variable: want_nocaseglob
+     Find potential files using the shell option `nocaseglob', when
+     `deplibs_check_method' is `file_magic'. Normally set to `no'. Set
+     to `yes' to enable the `nocaseglob' shell option when looking for
+     potential file names in a case-insensitive manner.
+
+ -- Variable: whole_archive_flag_spec
+     Compiler flag to generate shared objects from convenience archives.
+
+ -- Variable: wl
+     The C compiler flag that allows libtool to pass a flag directly to
+     the linker.  Used as: `${wl}SOME-FLAG'.
+
+   Variables ending in `_cmds' or `_eval' contain a `~'-separated list
+of commands that are `eval'ed one after another.  If any of the
+commands return a nonzero exit status, libtool generally exits with an
+error message.
+
+   Variables ending in `_spec' are `eval'ed before being used by
+libtool.

+File: libtool.info,  Node: Cheap tricks,  Prev: libtool script contents,  Up: Maintaining
+
+15.5 Cheap tricks
+=================
+
+Here are a few tricks that you can use in order to make maintainership
+easier:
+
+   * When people report bugs, ask them to use the `--config',
+     `--debug', or `--features' flags, if you think they will help you.
+     These flags are there to help you get information directly, rather
+     than having to trust second-hand observation.
+
+   * Rather than reconfiguring libtool every time I make a change to
+     `ltmain.in', I keep a permanent `libtool' script in my `PATH',
+     which sources `ltmain.in' directly.
+
+     The following steps describe how to create such a script, where
+     `/home/src/libtool' is the directory containing the libtool source
+     tree, `/home/src/libtool/libtool' is a libtool script that has been
+     configured for your platform, and `~/bin' is a directory in your
+     `PATH':
+
+          trick$ cd ~/bin
+          trick$ sed 's%^\(macro_version=\).*$%\1@VERSION@%;
+                      s%^\(macro_revision=\).*$%\1@package_revision@%;
+                      /^# ltmain\.sh/q' /home/src/libtool/libtool > libtool
+          trick$ echo '. /home/src/libtool/ltmain.in' >> libtool
+          trick$ chmod +x libtool
+          trick$ libtool --version
+          ltmain.sh (GNU @PACKAGE@@TIMESTAMP@) @VERSION@
+
+          Copyright (C) 2011 Free Software Foundation, Inc.
+          This is free software; see the source for copying conditions.  There is NO
+          warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
+          trick$
+
+   The output of the final `libtool --version' command shows that the
+`ltmain.in' script is being used directly.  Now, modify `~/bin/libtool'
+or `/home/src/libtool/ltmain.in' directly in order to test new changes
+without having to rerun `configure'.

+GNU M4
+******
+
+This manual (22 September 2013) is for GNU M4 (version 1.4.17), a
+package containing an implementation of the m4 macro language.
+
+   Copyright (C) 1989-1994, 2004-2013 Free Software Foundation, Inc.
+
+     Permission is granted to copy, distribute and/or modify this
+     document under the terms of the GNU Free Documentation License,
+     Version 1.3 or any later version published by the Free Software
+     Foundation; with no Invariant Sections, no Front-Cover Texts, and
+     no Back-Cover Texts.  A copy of the license is included in the
+     section entitled "GNU Free Documentation License."
+
+   GNU 'm4' is an implementation of the traditional UNIX macro
+processor.  It is mostly SVR4 compatible, although it has some
+extensions (for example, handling more than 9 positional parameters to
+macros).  'm4' also has builtin functions for including files, running
+shell commands, doing arithmetic, etc.  Autoconf needs GNU 'm4' for
+generating 'configure' scripts, but not for running them.
+
+   GNU 'm4' was originally written by Rene' Seindal, with subsequent
+changes by Franc,ois Pinard and other volunteers on the Internet.  All
+names and email addresses can be found in the files 'm4-1.4.17/AUTHORS'
+and 'm4-1.4.17/THANKS' from the GNU M4 distribution.
+
+   This is release 1.4.17.  It is now considered stable: future releases
+in the 1.4.x series are only meant to fix bugs, increase speed, or
+improve documentation.  However...
+
+   An experimental feature, which would improve 'm4' usefulness, allows
+for changing the syntax for what is a "word" in 'm4'.  You should use:
+     ./configure --enable-changeword
+if you want this feature compiled in.  The current implementation slows
+down 'm4' considerably and is hardly acceptable.  In the future, 'm4'

+
+1.1 Introduction to 'm4'
+========================
+
+'m4' is a macro processor, in the sense that it copies its input to the
+output, expanding macros as it goes.  Macros are either builtin or
+user-defined, and can take any number of arguments.  Besides just doing
+macro expansion, 'm4' has builtin functions for including named files,
+running shell commands, doing integer arithmetic, manipulating text in
+various ways, performing recursion, etc.... 'm4' can be used either as a
+front-end to a compiler, or as a macro processor in its own right.
+
+   The 'm4' macro processor is widely available on all UNIXes, and has
+been standardized by POSIX. Usually, only a small percentage of users
+are aware of its existence.  However, those who find it often become
+committed users.  The popularity of GNU Autoconf, which requires GNU
+'m4' for _generating_ 'configure' scripts, is an incentive for many to
+install it, while these people will not themselves program in 'm4'.  GNU
+'m4' is mostly compatible with the System V, Release 4 version, except
+for some minor differences.  *Note Compatibility::, for more details.
+
+   Some people find 'm4' to be fairly addictive.  They first use 'm4'
+for simple problems, then take bigger and bigger challenges, learning
+how to write complex sets of 'm4' macros along the way.  Once really
+addicted, users pursue writing of sophisticated 'm4' applications even
+to solve simple problems, devoting more time debugging their 'm4'
+scripts than doing real work.  Beware that 'm4' may be dangerous for the
+health of compulsive programmers.

+
+1.2 Historical references
+=========================
+
+Macro languages were invented early in the history of computing.  In the
+1950s Alan Perlis suggested that the macro language be independent of
+the language being processed.  Techniques such as conditional and
+recursive macros, and using macros to define other macros, were
+described by Doug McIlroy of Bell Labs in "Macro Instruction Extensions
+of Compiler Languages", _Communications of the ACM_ 3, 4 (1960), 214-20,
+<http://dx.doi.org/10.1145/367177.367223>.
+
+   An important precursor of 'm4' was GPM; see C. Strachey, "A general
+purpose macrogenerator", _Computer Journal_ 8, 3 (1965), 225-41,
+<http://dx.doi.org/10.1093/comjnl/8.3.225>.  GPM is also succinctly
+described in David Gries's book _Compiler Construction for Digital
+Computers_, Wiley (1971).  Strachey was a brilliant programmer: GPM fit
+into 250 machine instructions!
+
+   Inspired by GPM while visiting Strachey's Lab in 1968, McIlroy wrote
+a model preprocessor in that fit into a page of Snobol 3 code, and
+McIlroy and Robert Morris developed a series of further models at Bell
+Labs.  Andrew D. Hall followed up with M6, a general purpose macro
+processor used to port the Fortran source code of the Altran computer
+algebra system; see Hall's "The M6 Macro Processor", Computing Science
+Technical Report #2, Bell Labs (1972),
+<http://cm.bell-labs.com/cm/cs/cstr/2.pdf>.  M6's source code consisted
+of about 600 Fortran statements.  Its name was the first of the 'm4'
+line.
+
+   The Brian Kernighan and P.J. Plauger book _Software Tools_,
+Addison-Wesley (1976), describes and implements a Unix macro-processor
+language, which inspired Dennis Ritchie to write 'm3', a macro processor
+for the AP-3 minicomputer.
+
+   Kernighan and Ritchie then joined forces to develop the original
+'m4', described in "The M4 Macro Processor", Bell Laboratories (1977),
+<http://wolfram.schneider.org/bsd/7thEdManVol2/m4/m4.pdf>.  It had only
+21 builtin macros.
+
+   While 'GPM' was more _pure_, 'm4' is meant to deal with the true
+intricacies of real life: macros can be recognized without being
+pre-announced, skipping whitespace or end-of-lines is easier, more
+constructs are builtin instead of derived, etc.
+
+   Originally, the Kernighan and Plauger macro-processor, and then 'm3',
+formed the engine for the Rational FORTRAN preprocessor, that is, the
+'Ratfor' equivalent of 'cpp'.  Later, 'm4' was used as a front-end for
+'Ratfor', 'C' and 'Cobol'.
+
+   Rene' Seindal released his implementation of 'm4', GNU 'm4', in 1990,
+with the aim of removing the artificial limitations in many of the
+traditional 'm4' implementations, such as maximum line length, macro
+size, or number of macros.
+
+   The late Professor A. Dain Samples described and implemented a
+further evolution in the form of 'M5': "User's Guide to the M5 Macro
+Language: 2nd edition", Electronic Announcement on comp.compilers
+newsgroup (1992).
+
+   Franc,ois Pinard took over maintenance of GNU 'm4' in 1992, until
+1994 when he released GNU 'm4' 1.4, which was the stable release for 10
+years.  It was at this time that GNU Autoconf decided to require GNU
+'m4' as its underlying engine, since all other implementations of 'm4'
+had too many limitations.
+
+   More recently, in 2004, Paul Eggert released 1.4.1 and 1.4.2 which
+addressed some long standing bugs in the venerable 1.4 release.  Then in
+2005, Gary V. Vaughan collected together the many patches to GNU 'm4'
+1.4 that were floating around the net and released 1.4.3 and 1.4.4.  And
+in 2006, Eric Blake joined the team and prepared patches for the release
+of 1.4.5, 1.4.6, 1.4.7, and 1.4.8.  More bug fixes were incorporated in
+2007, with releases 1.4.9 and 1.4.10.  Eric continued with some
+portability fixes for 1.4.11 and 1.4.12 in 2008, 1.4.13 in 2009, 1.4.14
+and 1.4.15 in 2010, and 1.4.16 in 2011.
+
+   Meanwhile, development has continued on new features for 'm4', such
+as dynamic module loading and additional builtins.  When complete, GNU
+'m4' 2.0 will start a new series of releases.

+
+1.3 Problems and bugs
+=====================
+
+If you have problems with GNU M4 or think you've found a bug, please
+report it.  Before reporting a bug, make sure you've actually found a
+real bug.  Carefully reread the documentation and see if it really says
+you can do what you're trying to do.  If it's not clear whether you
+should be able to do something or not, report that too; it's a bug in
+the documentation!
+
+   Before reporting a bug or trying to fix it yourself, try to isolate
+it to the smallest possible input file that reproduces the problem.
+Then send us the input file and the exact results 'm4' gave you.  Also
+say what you expected to occur; this will help us decide whether the
+problem was really in the documentation.
+
+   Once you've got a precise problem, send e-mail to <bug-m4@gnu.org>.
+Please include the version number of 'm4' you are using.  You can get
+this information with the command 'm4 --version'.  Also provide details
+about the platform you are executing on.
+
+   Non-bug suggestions are always welcome as well.  If you have
+questions about things that are unclear in the documentation or are just
+obscure features, please report them too.
+
+
+File: m4.info,  Node: Manual,  Prev: Bugs,  Up: Preliminaries
+
+1.4 Using this manual
+=====================
+
+This manual contains a number of examples of 'm4' input and output, and
+a simple notation is used to distinguish input, output and error
+messages from 'm4'.  Examples are set out from the normal text, and
+shown in a fixed width font, like this
+
+     This is an example of an example!
+
+   To distinguish input from output, all output from 'm4' is prefixed by
+the string '=>', and all error messages by the string 'error->'.  When
+showing how command line options affect matters, the command line is
+shown with a prompt '$ 'like this'', otherwise, you can assume that a
+simple 'm4' invocation will work.  Thus:
+
+     $ command line to invoke m4
+     Example of input line
+     =>Output line from m4
+     error->and an error message
+
+   The sequence '^D' in an example indicates the end of the input file.
+The sequence '<NL>' refers to the newline character.  The majority of
+these examples are self-contained, and you can run them with similar
+results by invoking 'm4 -d'.  In fact, the testsuite that is bundled in
+the GNU M4 package consists of the examples in this document!  Some of
+the examples assume that your current directory is located where you
+unpacked the installation, so if you plan on following along, you may
+find it helpful to do this now:
+
+     $ cd m4-1.4.17
+
+   As each of the predefined macros in 'm4' is described, a prototype
+call of the macro will be shown, giving descriptive names to the
+arguments, e.g.,
+
+ -- Composite: example (STRING, [COUNT = '1']
+     [ARGUMENT]This is a sample prototype.  There is not really a macro
+     named 'example', but this documents that if there were, it would be
+     a Composite macro, rather than a Builtin.  It requires at least one
+     argument, STRING.  Remember that in 'm4', there must not be a space
+     between the macro name and the opening parenthesis, unless it was
+     intended to call the macro without any arguments.  The brackets
+     around COUNT and ARGUMENT show that these arguments are optional.
+     If COUNT is omitted, the macro behaves as if count were '1',
+     whereas if ARGUMENT is omitted, the macro behaves as if it were the
+     empty string.  A blank argument is not the same as an omitted
+     argument.  For example, 'example(`a')', 'example(`a',`1')', and
+     'example(`a',`1',)' would behave identically with COUNT set to '1';
+     while 'example(`a',)' and 'example(`a',`')' would explicitly pass
+     the empty string for COUNT.  The ellipses ('...') show that the
+     macro processes additional arguments after ARGUMENT, rather than
+     ignoring them.
+
+   All macro arguments in 'm4' are strings, but some are given special
+interpretation, e.g., as numbers, file names, regular expressions, etc.
+The documentation for each macro will state how the parameters are
+interpreted, and what happens if the argument cannot be parsed according
+to the desired interpretation.  Unless specified otherwise, a parameter
+specified to be a number is parsed as a decimal, even if the argument
+has leading zeros; and parsing the empty string as a number results in 0
+rather than an error, although a warning will be issued.
+
+   This document consistently writes and uses "builtin", without a
+hyphen, as if it were an English word.  This is how the 'builtin'
+primitive is spelled within 'm4'.

+
+2 Invoking 'm4'
+***************
+
+The format of the 'm4' command is:
+
+     m4 [OPTION...] [FILE...]
+
+   All options begin with '-', or if long option names are used, with
+'--'.  A long option name need not be written completely, any
+unambiguous prefix is sufficient.  POSIX requires 'm4' to recognize
+arguments intermixed with files, even when 'POSIXLY_CORRECT' is set in
+the environment.  Most options take effect at startup regardless of
+their position, but some are documented below as taking effect after any
+files that occurred earlier in the command line.  The argument '--' is a
+marker to denote the end of options.
+
+   With short options, options that do not take arguments may be
+combined into a single command line argument with subsequent options,
+options with mandatory arguments may be provided either as a single
+command line argument or as two arguments, and options with optional
+arguments must be provided as a single argument.  In other words, 'm4
+-QPDfoo -d a -df' is equivalent to 'm4 -Q -P -D foo -d -df -- ./a',
+although the latter form is considered canonical.
+
+   With long options, options with mandatory arguments may be provided
+with an equal sign ('=') in a single argument, or as two arguments, and
+options with optional arguments must be provided as a single argument.
+In other words, 'm4 --def foo --debug a' is equivalent to 'm4
+--define=foo --debug= -- ./a', although the latter form is considered
+canonical (not to mention more robust, in case a future version of 'm4'
+introduces an option named '--default').
+
+   'm4' understands the following options, grouped by functionality.

+
+* Operation modes::             Command line options for operation modes
+* Preprocessor features::       Command line options for preprocessor features

+File: m4.info,  Node: Operation modes,  Next: Preprocessor features,  Up: Invoking m4
+
+2.1 Command line options for operation modes
+============================================
+
+Several options control the overall operation of 'm4':
+
+'--help'
+     Print a help summary on standard output, then immediately exit 'm4'
+     without reading any input files or performing any other actions.
+
+'--version'
+     Print the version number of the program on standard output, then
+     immediately exit 'm4' without reading any input files or performing
+     any other actions.
+
+'-E'
+'--fatal-warnings'
+     Controls the effect of warnings.  If unspecified, then execution
+     continues and exit status is unaffected when a warning is printed.
+     If specified exactly once, warnings become fatal; when one is
+     issued, execution continues, but the exit status will be non-zero.
+     If specified multiple times, then execution halts with non-zero
+     status the first time a warning is issued.  The introduction of
+     behavior levels is new to M4 1.4.9; for behavior consistent with
+     earlier versions, you should specify '-E' twice.
+
+'-i'
+'--interactive'
+'-e'
+     Makes this invocation of 'm4' interactive.  This means that all
+     output will be unbuffered, and interrupts will be ignored.  The
+     spelling '-e' exists for compatibility with other 'm4'
+     implementations, and issues a warning because it may be withdrawn
+     in a future version of GNU M4.
+
+'-P'
+'--prefix-builtins'
+     Internally modify _all_ builtin macro names so they all start with
+     the prefix 'm4_'.  For example, using this option, one should write
+     'm4_define' instead of 'define', and 'm4___file__' instead of
+     '__file__'.  This option has no effect if '-R' is also specified.
+
+'-Q'
+'--quiet'
+'--silent'
+     Suppress warnings, such as missing or superfluous arguments in
+     macro calls, or treating the empty string as zero.
+
+'--warn-macro-sequence[=REGEXP]'
+     Issue a warning if the regular expression REGEXP has a non-empty
+     match in any macro definition (either by 'define' or 'pushdef').
+     Empty matches are ignored; therefore, supplying the empty string as
+     REGEXP disables any warning.  If the optional REGEXP is not
+     supplied, then the default regular expression is
+     '\$\({[^}]*}\|[0-9][0-9]+\)' (a literal '$' followed by multiple
+     digits or by an open brace), since these sequences will change
+     semantics in the default operation of GNU M4 2.0 (due to a change
+     in how more than 9 arguments in a macro definition will be handled,
+     *note Arguments::).  Providing an alternate regular expression can
+     provide a useful reverse lookup feature of finding where a macro is
+     defined to have a given definition.
+
+'-W REGEXP'
+'--word-regexp=REGEXP'
+     Use REGEXP as an alternative syntax for macro names.  This
+     experimental option will not be present in all GNU 'm4'
+     implementations (*note Changeword::).

+
+2.2 Command line options for preprocessor features
+==================================================
+
+Several options allow 'm4' to behave more like a preprocessor.  Macro
+definitions and deletions can be made on the command line, the search
+path can be altered, and the output file can track where the input came
+from.  These features occur with the following options:
+
+'-D NAME[=VALUE]'
+'--define=NAME[=VALUE]'
+     This enters NAME into the symbol table.  If '=VALUE' is missing,
+     the value is taken to be the empty string.  The VALUE can be any
+     string, and the macro can be defined to take arguments, just as if
+     it was defined from within the input.  This option may be given
+     more than once; order with respect to file names is significant,
+     and redefining the same NAME loses the previous value.
+
+'-I DIRECTORY'
+'--include=DIRECTORY'
+     Make 'm4' search DIRECTORY for included files that are not found in
+     the current working directory.  *Note Search Path::, for more
+     details.  This option may be given more than once.
+
+'-s'
+'--synclines'
+     Generate synchronization lines, for use by the C preprocessor or
+     other similar tools.  Order is significant with respect to file
+     names.  This option is useful, for example, when 'm4' is used as a
+     front end to a compiler.  Source file name and line number
+     information is conveyed by directives of the form '#line LINENUM
+     "FILE"', which are inserted as needed into the middle of the
+     output.  Such directives mean that the following line originated or
+     was expanded from the contents of input file FILE at line LINENUM.
+     The '"FILE"' part is often omitted when the file name did not
+     change from the previous directive.
+
+     Synchronization directives are always given on complete lines by
+     themselves.  When a synchronization discrepancy occurs in the
+     middle of an output line, the associated synchronization directive
+     is delayed until the next newline that does not occur in the middle
+     of a quoted string or comment.
+
+          define(`twoline', `1
+          2')

+          =>three
+          goodbye
+          =>#line 12
+          =>goodbye
+
+'-U NAME'
+'--undefine=NAME'
+     This deletes any predefined meaning NAME might have.  Obviously,
+     only predefined macros can be deleted in this way.  This option may
+     be given more than once; undefining a NAME that does not have a
+     definition is silently ignored.  Order is significant with respect
+     to file names.

+
+2.3 Command line options for limits control
+===========================================
+
+There are some limits within 'm4' that can be tuned.  For compatibility,
+'m4' also accepts some options that control limits in other
+implementations, but which are automatically unbounded (limited only by
+your hardware and operating system constraints) in GNU 'm4'.
+
+'-g'
+'--gnu'
+     Enable all the extensions in this implementation.  In this release
+     of M4, this option is always on by default; it is currently only
+     useful when overriding a prior use of '--traditional'.  However,
+     having GNU behavior as default makes it impossible to write a
+     strictly POSIX-compliant client that avoids all incompatible GNU M4
+     extensions, since such a client would have to use the non-POSIX
+     command-line option to force full POSIX behavior.  Thus, a future
+     version of M4 will be changed to implicitly use the option
+     '--traditional' if the environment variable 'POSIXLY_CORRECT' is
+     set.  Projects that intentionally use GNU extensions should
+     consider using '--gnu' to state their intentions, so that the
+     project will not mysteriously break if the user upgrades to a newer
+     M4 and has 'POSIXLY_CORRECT' set in their environment.
+
+'-G'
+'--traditional'
+     Suppress all the extensions made in this implementation, compared
+     to the System V version.  *Note Compatibility::, for a list of
+     these.
+
+'-H NUM'
+'--hashsize=NUM'
+     Make the internal hash table for symbol lookup be NUM entries big.
+     For better performance, the number should be prime, but this is not
+     checked.  The default is 509 entries.  It should not be necessary
+     to increase this value, unless you define an excessive number of
+     macros.
+
+'-L NUM'
+'--nesting-limit=NUM'
+     Artificially limit the nesting of macro calls to NUM levels,
+     stopping program execution if this limit is ever exceeded.  When
+     not specified, nesting defaults to unlimited on platforms that can
+     detect stack overflow, and to 1024 levels otherwise.  A value of
+     zero means unlimited; but then heavily nested code could
+     potentially cause a stack overflow.
+
+     The precise effect of this option is more correctly associated with
+     textual nesting than dynamic recursion.  It has been useful when
+     some complex 'm4' input was generated by mechanical means, and also
+     in diagnosing recursive algorithms that do not scale well.  Most
+     users never need to change this option from its default.
+
+     This option does _not_ have the ability to break endless rescanning
+     loops, since these do not necessarily consume much memory or stack
+     space.  Through clever usage of rescanning loops, one can request
+     complex, time-consuming computations from 'm4' with useful results.
+     Putting limitations in this area would break 'm4' power.  There are
+     many pathological cases: 'define(`a', `a')a' is only the simplest
+     example (but *note Compatibility::).  Expecting GNU 'm4' to detect
+     these would be a little like expecting a compiler system to detect
+     and diagnose endless loops: it is a quite _hard_ problem in
+     general, if not undecidable!
+
+'-B NUM'
+'-S NUM'
+'-T NUM'
+     These options are present for compatibility with System V 'm4', but
+     do nothing in this implementation.  They may disappear in future
+     releases, and issue a warning to that effect.
+
+'-N NUM'
+'--diversions=NUM'
+     These options are present only for compatibility with previous
+     versions of GNU 'm4', and were controlling the number of possible
+     diversions which could be used at the same time.  They do nothing,
+     because there is no fixed limit anymore.  They may disappear in
+     future releases, and issue a warning to that effect.

+
+2.4 Command line options for frozen state
+=========================================
+
+GNU 'm4' comes with a feature of freezing internal state (*note Frozen
+files::).  This can be used to speed up 'm4' execution when reusing a
+common initialization script.
+
+'-F FILE'
+'--freeze-state=FILE'
+     Once execution is finished, write out the frozen state on the
+     specified FILE.  It is conventional, but not required, for FILE to
+     end in '.m4f'.
+
+'-R FILE'
+'--reload-state=FILE'
+     Before execution starts, recover the internal state from the
+     specified frozen FILE.  The options '-D', '-U', and '-t' take
+     effect after state is reloaded, but before the input files are
+     read.

+
+2.5 Command line options for debugging
+======================================
+
+Finally, there are several options for aiding in debugging 'm4' scripts.
+
+'-d[FLAGS]'
+'--debug[=FLAGS]'
+     Set the debug-level according to the flags FLAGS.  The debug-level
+     controls the format and amount of information presented by the
+     debugging functions.  *Note Debug Levels::, for more details on the
+     format and meaning of FLAGS.  If omitted, FLAGS defaults to 'aeq'.
+
+'--debugfile[=FILE]'
+'-o FILE'
+'--error-output=FILE'
+     Redirect 'dumpdef' output, debug messages, and trace output to the
+     named FILE.  Warnings, error messages, and 'errprint' output are
+     still printed to standard error.  If these options are not used, or
+     if FILE is unspecified (only possible for '--debugfile'), debug
+     output goes to standard error; if FILE is the empty string, debug
+     output is discarded.  *Note Debug Output::, for more details.  The
+     option '--debugfile' may be given more than once, and order is
+     significant with respect to file names.  The spellings '-o' and
+     '--error-output' are misleading and inconsistent with other GNU
+     tools; for now they are silently accepted as synonyms of
+     '--debugfile' and only recognized once, but in a future version of
+     M4, using them will cause a warning to be issued.
+
+'-l NUM'
+'--arglength=NUM'
+     Restrict the size of the output generated by macro tracing to NUM
+     characters per trace line.  If unspecified or zero, output is
+     unlimited.  *Note Debug Levels::, for more details.
+
+'-t NAME'
+'--trace=NAME'
+     This enables tracing for the macro NAME, at any point where it is
+     defined.  NAME need not be defined when this option is given.  This
+     option may be given more than once, and order is significant with
+     respect to file names.  *Note Trace::, for more details.

+
+2.6 Specifying input files on the command line
+==============================================
+
+The remaining arguments on the command line are taken to be input file
+names.  If no names are present, standard input is read.  A file name of
+'-' is taken to mean standard input.  It is conventional, but not
+required, for input files to end in '.m4'.
+
+   The input files are read in the sequence given.  Standard input can
+be read more than once, so the file name '-' may appear multiple times
+on the command line; this makes a difference when input is from a
+terminal or other special file type.  It is an error if an input file
+ends in the middle of argument collection, a comment, or a quoted
+string.
+
+   The options '--define' ('-D'), '--undefine' ('-U'), '--synclines'
+('-s'), and '--trace' ('-t') only take effect after processing input
+from any file names that occur earlier on the command line.  For
+example, assume the file 'foo' contains:
+
+     $ cat foo
+     bar
+
+   The text 'bar' can then be redefined over multiple uses of 'foo':
+
+     $ m4 -Dbar=hello foo -Dbar=world foo
+     =>hello
+     =>world
+
+   If none of the input files invoked 'm4exit' (*note M4exit::), the
+exit status of 'm4' will be 0 for success, 1 for general failure (such
+as problems with reading an input file), and 63 for version mismatch
+(*note Using frozen files::).
+
+   If you need to read a file whose name starts with a '-', you can
+specify it as './-file', or use '--' to mark the end of options.

+
+3 Lexical and syntactic conventions
+***********************************
+
+As 'm4' reads its input, it separates it into "tokens".  A token is
+either a name, a quoted string, or any single character, that is not a
+part of either a name or a string.  Input to 'm4' can also contain
+comments.  GNU 'm4' does not yet understand multibyte locales; all
+operations are byte-oriented rather than character-oriented (although if
+your locale uses a single byte encoding, such as ISO-8859-1, you will
+not notice a difference).  However, 'm4' is eight-bit clean, so you can
+use non-ASCII characters in quoted strings (*note Changequote::),
+comments (*note Changecom::), and macro names (*note Indir::), with the
+exception of the NUL character (the zero byte ''\0'').

+File: m4.info,  Node: Names,  Next: Quoted strings,  Up: Syntax
+
+3.1 Macro names
+===============
+
+A name is any sequence of letters, digits, and the character '_'
+(underscore), where the first character is not a digit.  'm4' will use
+the longest such sequence found in the input.  If a name has a macro
+definition, it will be subject to macro expansion (*note Macros::).
+Names are case-sensitive.
+
+   Examples of legal names are: 'foo', '_tmp', and 'name01'.
+
+
+File: m4.info,  Node: Quoted strings,  Next: Comments,  Prev: Names,  Up: Syntax
+
+3.2 Quoting input to 'm4'
+=========================
+
+A quoted string is a sequence of characters surrounded by quote strings,
+defaulting to '`' and ''', where the nested begin and end quotes within
+the string are balanced.  The value of a string token is the text, with
+one level of quotes stripped off.  Thus
+
+     `'
+     =>
+
+is the empty string, and double-quoting turns into single-quoting.
+
+     ``quoted''
+     =>`quoted'
+
+   The quote characters can be changed at any time, using the builtin
+macro 'changequote'.  *Note Changequote::, for more information.
+
+
+File: m4.info,  Node: Comments,  Next: Other tokens,  Prev: Quoted strings,  Up: Syntax
+
+3.3 Comments in 'm4' input
+==========================
+
+Comments in 'm4' are normally delimited by the characters '#' and
+newline.  All characters between the comment delimiters are ignored, but
+the entire comment (including the delimiters) is passed through to the
+output--comments are _not_ discarded by 'm4'.
+
+   Comments cannot be nested, so the first newline after a '#' ends the
+comment.  The commenting effect of the begin-comment string can be
+inhibited by quoting it.
+
+     $ m4
+     `quoted text' # `commented text'
+     =>quoted text # `commented text'
+     `quoting inhibits' `#' `comments'
+     =>quoting inhibits # comments
+
+   The comment delimiters can be changed to any string at any time,
+using the builtin macro 'changecom'.  *Note Changecom::, for more
+information.
+
+
+File: m4.info,  Node: Other tokens,  Next: Input processing,  Prev: Comments,  Up: Syntax
+
+3.4 Other kinds of input tokens
+===============================
+
+Any character, that is neither a part of a name, nor of a quoted string,
+nor a comment, is a token by itself.  When not in the context of macro
+expansion, all of these tokens are just copied to output.  However,
+during macro expansion, whitespace characters (space, tab, newline,
+formfeed, carriage return, vertical tab), parentheses ('(' and ')'),
+comma (','), and dollar ('$') have additional roles, explained later.
+
+
+File: m4.info,  Node: Input processing,  Prev: Other tokens,  Up: Syntax
+
+3.5 How 'm4' copies input to output
+===================================
+
+As 'm4' reads the input token by token, it will copy each token directly
+to the output immediately.
+
+   The exception is when it finds a word with a macro definition.  In
+that case 'm4' will calculate the macro's expansion, possibly reading
+more input to get the arguments.  It then inserts the expansion in front
+of the remaining input.  In other words, the resulting text from a macro
+call will be read and parsed into tokens again.
+
+   'm4' expands a macro as soon as possible.  If it finds a macro call
+when collecting the arguments to another, it will expand the second call
+first.  This process continues until there are no more macro calls to
+expand and all the input has been consumed.
+
+   For a running example, examine how 'm4' handles this input:
+
+     format(`Result is %d', eval(`2**15'))
+
+First, 'm4' sees that the token 'format' is a macro name, so it collects
+the tokens '(', '`Result is %d'', ',', and ' ', before encountering
+another potential macro.  Sure enough, 'eval' is a macro name, so the
+nested argument collection picks up '(', '`2**15'', and ')', invoking
+the eval macro with the lone argument of '2**15'.  The expansion of
+'eval(2**15)' is '32768', which is then rescanned as the five tokens
+'3', '2', '7', '6', and '8'; and combined with the next ')', the format
+macro now has all its arguments, as if the user had typed:
+
+     format(`Result is %d', 32768)
+
+The format macro expands to 'Result is 32768', and we have another round
+of scanning for the tokens 'Result', ' ', 'is', ' ', '3', '2', '7', '6',
+and '8'.  None of these are macros, so the final output is
+
+     =>Result is 32768
+
+   As a more complicated example, we will contrast an actual code
+example from the Gnulib project(1), showing both a buggy approach and
+the desired results.  The user desires to output a shell assignment
+statement that takes its argument and turns it into a shell variable by
+converting it to uppercase and prepending a prefix.  The original
+attempt looks like this:
+
+     changequote([,])dnl
+     define([gl_STRING_MODULE_INDICATOR],
+       [
+         dnl comment
+         GNULIB_]translit([$1],[a-z],[A-Z])[=1
+       ])dnl
+       gl_STRING_MODULE_INDICATOR([strcase])
+     =>  
+     =>        GNULIB_strcase=1
+     =>  
+
+   Oops - the argument did not get capitalized.  And although the manual
+is not able to easily show it, both lines that appear empty actually
+contain two trailing spaces.  By stepping through the parse, it is easy
+to see what happened.  First, 'm4' sees the token 'changequote', which
+it recognizes as a macro, followed by '(', '[', ',', ']', and ')' to
+form the argument list.  The macro expands to the empty string, but
+changes the quoting characters to something more useful for generating
+shell code (unbalanced '`' and ''' appear all the time in shell scripts,
+but unbalanced '[]' tend to be rare).  Also in the first line, 'm4' sees
+the token 'dnl', which it recognizes as a builtin macro that consumes
+the rest of the line, resulting in no output for that line.
+
+   The second line starts a macro definition.  'm4' sees the token
+'define', which it recognizes as a macro, followed by a '(',
+'[gl_STRING_MODULE_INDICATOR]', and ','.  Because an unquoted comma was
+encountered, the first argument is known to be the expansion of the
+single-quoted string token, or 'gl_STRING_MODULE_INDICATOR'.  Next, 'm4'
+sees '<NL>', ' ', and ' ', but this whitespace is discarded as part of
+argument collection.  Then comes a rather lengthy single-quoted string
+token, '[<NL>    dnl comment<NL>    GNULIB_]'.  This is followed by the
+token 'translit', which 'm4' recognizes as a macro name, so a nested
+macro expansion has started.
+
+   The arguments to the 'translit' are found by the tokens '(', '[$1]',
+',', '[a-z]', ',', '[A-Z]', and finally ')'.  All three string arguments
+are expanded (or in other words, the quotes are stripped), and since
+neither '$' nor '1' need capitalization, the result of the macro is
+'$1'.  This expansion is rescanned, resulting in the two literal
+characters '$' and '1'.
+
+   Scanning of the outer macro resumes, and picks up with '[=1<NL>  ]',
+and finally ')'.  The collected pieces of expanded text are
+concatenated, with the end result that the macro
+'gl_STRING_MODULE_INDICATOR' is now defined to be the sequence
+'<NL>    dnl comment<NL>    GNULIB_$1=1<NL>  '.  Once again, 'dnl' is
+recognized and avoids a newline in the output.
+
+   The final line is then parsed, beginning with ' ' and ' ' that are
+output literally.  Then 'gl_STRING_MODULE_INDICATOR' is recognized as a
+macro name, with an argument list of '(', '[strcase]', and ')'.  Since
+the definition of the macro contains the sequence '$1', that sequence is
+replaced with the argument 'strcase' prior to starting the rescan.  The
+rescan sees '<NL>' and four spaces, which are output literally, then
+'dnl', which discards the text ' comment<NL>'.  Next comes four more
+spaces, also output literally, and the token 'GNULIB_strcase', which
+resulted from the earlier parameter substitution.  Since that is not a
+macro name, it is output literally, followed by the literal tokens '=',
+'1', '<NL>', and two more spaces.  Finally, the original '<NL>' seen
+after the macro invocation is scanned and output literally.
+
+   Now for a corrected approach.  This rearranges the use of newlines
+and whitespace so that less whitespace is output (which, although
+harmless to shell scripts, can be visually unappealing), and fixes the
+quoting issues so that the capitalization occurs when the macro
+'gl_STRING_MODULE_INDICATOR' is invoked, rather then when it is defined.
+It also adds another layer of quoting to the first argument of
+'translit', to ensure that the output will be rescanned as a string
+rather than a potential uppercase macro name needing further expansion.
+
+     changequote([,])dnl
+     define([gl_STRING_MODULE_INDICATOR],
+       [dnl comment
+       GNULIB_[]translit([[$1]], [a-z], [A-Z])=1dnl
+     ])dnl
+       gl_STRING_MODULE_INDICATOR([strcase])
+     =>    GNULIB_STRCASE=1
+
+   The parsing of the first line is unchanged.  The second line sees the
+name of the macro to define, then sees the discarded '<NL>' and two
+spaces, as before.  But this time, the next token is '[dnl
+comment<NL>  GNULIB_[]translit([[$1]], [a-z], [A-Z])=1dnl<NL>]', which
+includes nested quotes, followed by ')' to end the macro definition and
+'dnl' to skip the newline.  No early expansion of 'translit' occurs, so
+the entire string becomes the definition of the macro.
+
+   The final line is then parsed, beginning with two spaces that are
+output literally, and an invocation of 'gl_STRING_MODULE_INDICATOR' with
+the argument 'strcase'.  Again, the '$1' in the macro definition is
+substituted prior to rescanning.  Rescanning first encounters 'dnl', and
+discards ' comment<NL>'.  Then two spaces are output literally.  Next
+comes the token 'GNULIB_', but that is not a macro, so it is output
+literally.  The token '[]' is an empty string, so it does not affect
+output.  Then the token 'translit' is encountered.
+
+   This time, the arguments to 'translit' are parsed as '(',
+'[[strcase]]', ',', ' ', '[a-z]', ',', ' ', '[A-Z]', and ')'.  The two
+spaces are discarded, and the translit results in the desired result
+'[STRCASE]'.  This is rescanned, but since it is a string, the quotes
+are stripped and the only output is a literal 'STRCASE'.  Then the
+scanner sees '=' and '1', which are output literally, followed by 'dnl'
+which discards the rest of the definition of
+'gl_STRING_MODULE_INDICATOR'.  The newline at the end of output is the
+literal '<NL>' that appeared after the invocation of the macro.
+
+   The order in which 'm4' expands the macros can be further explored
+using the trace facilities of GNU 'm4' (*note Trace::).

+4.1 Macro invocation
+====================
+
+Macro invocations has one of the forms
+
+     name
+
+which is a macro invocation without any arguments, or
+
+     name(arg1, arg2, ..., argN)
+
+which is a macro invocation with N arguments.  Macros can have any
+number of arguments.  All arguments are strings, but different macros
+might interpret the arguments in different ways.
+
+   The opening parenthesis _must_ follow the NAME directly, with no
+spaces in between.  If it does not, the macro is called with no
+arguments at all.
+
+   For a macro call to have no arguments, the parentheses _must_ be left
+out.  The macro call
+
+     name()
+
+is a macro call with one argument, which is the empty string, not a call
+with no arguments.
+

+
+4.2 Preventing macro invocation
+===============================
+
+An innovation of the 'm4' language, compared to some of its predecessors
+(like Strachey's 'GPM', for example), is the ability to recognize macro
+calls without resorting to any special, prefixed invocation character.
+While generally useful, this feature might sometimes be the source of
+spurious, unwanted macro calls.  So, GNU 'm4' offers several mechanisms
+or techniques for inhibiting the recognition of names as macro calls.
+
+   First of all, many builtin macros cannot meaningfully be called
+without arguments.  As a GNU extension, for any of these macros,
+whenever an opening parenthesis does not immediately follow their name,
+the builtin macro call is not triggered.  This solves the most usual
+cases, like for 'include' or 'eval'.  Later in this document, the
+sentence "This macro is recognized only with parameters" refers to this
+specific provision of GNU M4, also known as a blind builtin macro.  For
+the builtins defined by POSIX that bear this disclaimer, POSIX
+specifically states that invoking those builtins without arguments is
+unspecified, because many other implementations simply invoke the
+builtin as though it were given one empty argument instead.
+
+     $ m4
+     eval
+     =>eval
+     eval(`1')
+     =>1
+
+   There is also a command line option ('--prefix-builtins', or '-P',
+*note Invoking m4: Operation modes.) that renames all builtin macros
+with a prefix of 'm4_' at startup.  The option has no effect whatsoever
+on user defined macros.  For example, with this option, one has to write
+'m4_dnl' and even 'm4_m4exit'.  It also has no effect on whether a macro
+requires parameters.
+
+     $ m4 -P
+     eval
+     =>eval
+     eval(`1')
+     =>eval(1)
+     m4_eval
+     =>m4_eval
+     m4_eval(`1')
+     =>1
+
+   Another alternative is to redefine problematic macros to a name less
+likely to cause conflicts, using *note Definitions::.
+
+   If your version of GNU 'm4' has the 'changeword' feature compiled in,
+it offers far more flexibility in specifying the syntax of macro names,
+both builtin or user-defined.  *Note Changeword::, for more information
+on this experimental feature.
+
+   Of course, the simplest way to prevent a name from being interpreted
+as a call to an existing macro is to quote it.  The remainder of this
+section studies a little more deeply how quoting affects macro
+invocation, and how quoting can be used to inhibit macro invocation.
+
+   Even if quoting is usually done over the whole macro name, it can
+also be done over only a few characters of this name (provided, of
+course, that the unquoted portions are not also a macro).  It is also
+possible to quote the empty string, but this works only _inside_ the
+name.  For example:
+
+     `divert'
+     =>divert
+     `d'ivert
+     =>divert
+     di`ver't
+     =>divert
+     div`'ert
+     =>divert
+
+all yield the string 'divert'.  While in both:
+
+     `'divert
+     =>
+     divert`'
+     =>
+
+the 'divert' builtin macro will be called, which expands to the empty
+string.
+
+   The output of macro evaluations is always rescanned.  In the
+following example, the input 'x`'y' yields the string 'bCD', exactly as
+if 'm4' has been given 'substr(ab`'cde, `1', `3')' as input:
+
+     define(`cde', `CDE')
+     =>
+     define(`x', `substr(ab')
+     =>
+     define(`y', `cde, `1', `3')')
+     =>
+     x`'y
+     =>bCD
+
+   Unquoted strings on either side of a quoted string are subject to
+being recognized as macro names.  In the following example, quoting the
+empty string allows for the second 'macro' to be recognized as such:
+
+     define(`macro', `m')
+     =>
+     macro(`m')macro
+     =>mmacro
+     macro(`m')`'macro
+     =>mm
+
+   Quoting may prevent recognizing as a macro name the concatenation of
+a macro expansion with the surrounding characters.  In this example:
+
+     define(`macro', `di$1')
+     =>
+     macro(`v')`ert'
+     =>divert
+     macro(`v')ert
+     =>
+
+the input will produce the string 'divert'.  When the quotes were
+removed, the 'divert' builtin was called instead.

+
+4.3 Macro arguments
+===================
+
+When a name is seen, and it has a macro definition, it will be expanded
+as a macro.
+
+   If the name is followed by an opening parenthesis, the arguments will
+be collected before the macro is called.  If too few arguments are
+supplied, the missing arguments are taken to be the empty string.
+However, some builtins are documented to behave differently for a
+missing optional argument than for an explicit empty string.  If there
+are too many arguments, the excess arguments are ignored.  Unquoted
+leading whitespace is stripped off all arguments, but whitespace
+generated by a macro expansion or occurring after a macro that expanded
+to an empty string remains intact.  Whitespace includes space, tab,
+newline, carriage return, vertical tab, and formfeed.
+
+     define(`macro', `$1')
+     =>
+     macro( unquoted leading space lost)
+     =>unquoted leading space lost
+     macro(` quoted leading space kept')
+     => quoted leading space kept
+     macro(
+      divert `unquoted space kept after expansion')
+     => unquoted space kept after expansion
+     macro(macro(`
+     ')`whitespace from expansion kept')
+     =>
+     =>whitespace from expansion kept
+     macro(`unquoted trailing whitespace kept'
+     )
+     =>unquoted trailing whitespace kept
+     =>
+
+   Normally 'm4' will issue warnings if a builtin macro is called with
+an inappropriate number of arguments, but it can be suppressed with the
+'--quiet' command line option (or '--silent', or '-Q', *note Invoking
+m4: Operation modes.).  For user defined macros, there is no check of
+the number of arguments given.
+
+     $ m4
+     index(`abc')
+     error->m4:stdin:1: Warning: too few arguments to builtin `index'
+     =>0
+     index(`abc',)
+     =>0
+     index(`abc', `b', `ignored')
+     error->m4:stdin:3: Warning: excess arguments to builtin `index' ignored
+     =>1
+
+     $ m4 -Q
+     index(`abc')
+     =>0
+     index(`abc',)
+     =>0
+     index(`abc', `b', `ignored')
+     =>1
+
+   Macros are expanded normally during argument collection, and whatever
+commas, quotes and parentheses that might show up in the resulting
+expanded text will serve to define the arguments as well.  Thus, if FOO
+expands to ', b, c', the macro call
+
+     bar(a foo, d)
+
+is a macro call with four arguments, which are 'a ', 'b', 'c' and 'd'.
+To understand why the first argument contains whitespace, remember that
+unquoted leading whitespace is never part of an argument, but trailing
+whitespace always is.
+
+   It is possible for a macro's definition to change during argument
+collection, in which case the expansion uses the definition that was in
+effect at the time the opening '(' was seen.
+
+     define(`f', `1')
+     =>
+     f(define(`f', `2'))
+     =>1
+     f
+     =>2
+
+   It is an error if the end of file occurs while collecting arguments.
+
+     hello world
+     =>hello world
+     define(
+     ^D
+     error->m4:stdin:2: ERROR: end of file in argument list
+
+

+
+4.4 On Quoting Arguments to macros
+==================================
+
+Each argument has unquoted leading whitespace removed.  Within each
+argument, all unquoted parentheses must match.  For example, if FOO is a
+macro,
+
+     foo(() (`(') `(')
+
+is a macro call, with one argument, whose value is '() (() ('.  Commas
+separate arguments, except when they occur inside quotes, comments, or
+unquoted parentheses.  *Note Pseudo Arguments::, for examples.
+
+   It is common practice to quote all arguments to macros, unless you
+are sure you want the arguments expanded.  Thus, in the above example
+with the parentheses, the 'right' way to do it is like this:
+
+     foo(`() (() (')
+
+   It is, however, in certain cases necessary (because nested expansion
+must occur to create the arguments for the outer macro) or convenient
+(because it uses fewer characters) to leave out quotes for some
+arguments, and there is nothing wrong in doing it.  It just makes life a
+bit harder, if you are not careful to follow a consistent quoting style.
+For consistency, this manual follows the rule of thumb that each layer
+of parentheses introduces another layer of single quoting, except when
+showing the consequences of quoting rules.  This is done even when the
+quoted string cannot be a macro, such as with integers when you have not
+changed the syntax via 'changeword' (*note Changeword::).
+
+   The quoting rule of thumb of one level of quoting per parentheses has
+a nice property: when a macro name appears inside parentheses, you can
+determine when it will be expanded.  If it is not quoted, it will be
+expanded prior to the outer macro, so that its expansion becomes the
+argument.  If it is single-quoted, it will be expanded after the outer
+macro.  And if it is double-quoted, it will be used as literal text
+instead of a macro name.
+
+     define(`active', `ACT, IVE')
+     =>
+     define(`show', `$1 $1')
+     =>
+     show(active)
+     =>ACT ACT
+     show(`active')
+     =>ACT, IVE ACT, IVE
+     show(``active'')
+     =>active active

+
+4.5 Macro expansion
+===================
+
+When the arguments, if any, to a macro call have been collected, the
+macro is expanded, and the expansion text is pushed back onto the input
+(unquoted), and reread.  The expansion text from one macro call might
+therefore result in more macros being called, if the calls are included,
+completely or partially, in the first macro calls' expansion.
+
+   Taking a very simple example, if FOO expands to 'bar', and BAR
+expands to 'Hello', the input
+
+     $ m4 -Dbar=Hello -Dfoo=bar
+     foo
+     =>Hello
+
+will expand first to 'bar', and when this is reread and expanded, into
+'Hello'.

+5 How to define new macros
+**************************
+
+Macros can be defined, redefined and deleted in several different ways.
+Also, it is possible to redefine a macro without losing a previous
+value, and bring back the original value at a later time.

+
+
+File: m4.info,  Node: Define,  Next: Arguments,  Up: Definitions
+
+5.1 Defining a macro
+====================
+
+The normal way to define or redefine macros is to use the builtin
+'define':
+
+ -- Builtin: define (NAME, [EXPANSION]
+     Defines NAME to expand to EXPANSION.  If EXPANSION is not given, it
+     is taken to be empty.
+
+     The expansion of 'define' is void.  The macro 'define' is
+     recognized only with parameters.
+
+   The following example defines the macro FOO to expand to the text
+'Hello World.'.
+
+     define(`foo', `Hello world.')
+     =>
+     foo
+     =>Hello world.
+
+   The empty line in the output is there because the newline is not a
+part of the macro definition, and it is consequently copied to the
+output.  This can be avoided by use of the macro 'dnl'.  *Note Dnl::,
+for details.
+
+   The first argument to 'define' should be quoted; otherwise, if the
+macro is already defined, you will be defining a different macro.  This
+example shows the problems with underquoting, since we did not want to
+redefine 'one':
+
+     define(foo, one)
+     =>
+     define(foo, two)
+     =>
+     one
+     =>two
+
+   GNU 'm4' normally replaces only the _topmost_ definition of a macro
+if it has several definitions from 'pushdef' (*note Pushdef::).  Some
+other implementations of 'm4' replace all definitions of a macro with
+'define'.  *Note Incompatibilities::, for more details.
+
+   As a GNU extension, the first argument to 'define' does not have to
+be a simple word.  It can be any text string, even the empty string.  A
+macro with a non-standard name cannot be invoked in the normal way, as
+the name is not recognized.  It can only be referenced by the builtins
+'indir' (*note Indir::) and 'defn' (*note Defn::).
+
+   Arrays and associative arrays can be simulated by using non-standard
+macro names.
+
+ -- Composite: array (INDEX)
+ -- Composite: array_set (INDEX, [VALUE]
+     Provide access to entries within an array.  'array' reads the entry
+     at location INDEX, and 'array_set' assigns VALUE to location INDEX.
+
+     define(`array', `defn(format(``array[%d]'', `$1'))')
+     =>
+     define(`array_set', `define(format(``array[%d]'', `$1'), `$2')')
+     =>
+     array_set(`4', `array element no. 4')
+     =>
+     array_set(`17', `array element no. 17')
+     =>
+     array(`4')
+     =>array element no. 4
+     array(eval(`10 + 7'))
+     =>array element no. 17
+
+   Change the '%d' to '%s' and it is an associative array.
+

+
+5.2 Arguments to macros
+=======================
+
+Macros can have arguments.  The Nth argument is denoted by '$n' in the
+expansion text, and is replaced by the Nth actual argument, when the
+macro is expanded.  Replacement of arguments happens before rescanning,
+regardless of how many nesting levels of quoting appear in the
+expansion.  Here is an example of a macro with two arguments.
+
+ -- Composite: exch (ARG1, ARG2)
+     Expands to ARG2 followed by ARG1, effectively exchanging their
+     order.
+
+     define(`exch', `$2, $1')
+     =>
+     exch(`arg1', `arg2')
+     =>arg2, arg1
+
+   This can be used, for example, if you like the arguments to 'define'
+to be reversed.
+
+     define(`exch', `$2, $1')
+     =>
+     define(exch(``expansion text'', ``macro''))
+     =>
+     macro
+     =>expansion text
+
+   *Note Quoting Arguments::, for an explanation of the double quotes.
+(You should try and improve this example so that clients of 'exch' do
+not have to double quote; or *note Answers: Improved exch.).
+
+   As a special case, the zeroth argument, '$0', is always the name of
+the macro being expanded.
+
+     define(`test', ``Macro name: $0'')
+     =>
+     test
+     =>Macro name: test
+
+   If you want quoted text to appear as part of the expansion text,
+remember that quotes can be nested in quoted strings.  Thus, in
+
+     define(`foo', `This is macro `foo'.')
+     =>
+     foo
+     =>This is macro foo.
+
+The 'foo' in the expansion text is _not_ expanded, since it is a quoted
+string, and not a name.
+
+   GNU 'm4' allows the number following the '$' to consist of one or
+more digits, allowing macros to have any number of arguments.  The
+extension of accepting multiple digits is incompatible with POSIX, and
+is different than traditional implementations of 'm4', which only
+recognize one digit.  Therefore, future versions of GNU M4 will phase
+out this feature.  To portably access beyond the ninth argument, you can
+use the 'argn' macro documented later (*note Shift::).
+
+   POSIX also states that '$' followed immediately by '{' in a macro
+definition is implementation-defined.  This version of M4 passes the
+literal characters '${' through unchanged, but M4 2.0 will implement an
+optional feature similar to 'sh', where '${11}' expands to the eleventh
+argument, to replace the current recognition of '$11'.  Meanwhile, if
+you want to guarantee that you will get a literal '${' in output when
+expanding a macro, even when you upgrade to M4 2.0, you can use nested
+quoting to your advantage:
+
+     define(`foo', `single quoted $`'{1} output')
+     =>
+     define(`bar', ``double quoted $'`{2} output'')
+     =>
+     foo(`a', `b')
+     =>single quoted ${1} output
+     bar(`a', `b')
+     =>double quoted ${2} output
+
+   To help you detect places in your M4 input files that might change in
+behavior due to the changed behavior of M4 2.0, you can use the
+'--warn-macro-sequence' command-line option (*note Invoking m4:
+Operation modes.) with the default regular expression.  This will add a
+warning any time a macro definition includes '$' followed by multiple
+digits, or by '{'.  The warning is not enabled by default, because it
+triggers a number of warnings in Autoconf 2.61 (and Autoconf uses '-E'
+to treat warnings as errors), and because it will still be possible to
+restore older behavior in M4 2.0.
+
+     $ m4 --warn-macro-sequence
+     define(`foo', `$001 ${1} $1')
+     error->m4:stdin:1: Warning: definition of `foo' contains sequence `$001'
+     error->m4:stdin:1: Warning: definition of `foo' contains sequence `${1}'
+     =>
+     foo(`bar')
+     =>bar ${1} bar
+

+
+5.3 Special arguments to macros
+===============================
+
+There is a special notation for the number of actual arguments supplied,
+and for all the actual arguments.
+
+   The number of actual arguments in a macro call is denoted by '$#' in
+the expansion text.
+
+ -- Composite: nargs (...)
+     Expands to a count of the number of arguments supplied.
+
+     define(`nargs', `$#')
+     =>
+     nargs
+     =>0
+     nargs()
+     =>1
+     nargs(`arg1', `arg2', `arg3')
+     =>3
+     nargs(`commas can be quoted, like this')
+     =>1
+     nargs(arg1#inside comments, commas do not separate arguments
+     still arg1)
+     =>1
+     nargs((unquoted parentheses, like this, group arguments))
+     =>1
+
+   Remember that '#' defaults to the comment character; if you forget
+quotes to inhibit the comment behavior, your macro definition may not
+end where you expected.
+
+     dnl Attempt to define a macro to just `$#'
+     define(underquoted, $#)
+     oops)
+     =>
+     underquoted
+     =>0)
+     =>oops
+
+   The notation '$*' can be used in the expansion text to denote all the
+actual arguments, unquoted, with commas in between.  For example
+
+     define(`echo', `$*')
+     =>
+     echo(arg1,    arg2, arg3 , arg4)
+     =>arg1,arg2,arg3 ,arg4
+
+   Often each argument should be quoted, and the notation '$@' handles
+that.  It is just like '$*', except that it quotes each argument.  A
+simple example of that is:
+
+     define(`echo', `$@')
+     =>
+     echo(arg1,    arg2, arg3 , arg4)
+     =>arg1,arg2,arg3 ,arg4
+
+   Where did the quotes go?  Of course, they were eaten, when the
+expanded text were reread by 'm4'.  To show the difference, try
+
+     define(`echo1', `$*')
+     =>
+     define(`echo2', `$@')
+     =>
+     define(`foo', `This is macro `foo'.')
+     =>
+     echo1(foo)
+     =>This is macro This is macro foo..
+     echo1(`foo')
+     =>This is macro foo.
+     echo2(foo)
+     =>This is macro foo.
+     echo2(`foo')
+     =>foo
+
+*Note Trace::, if you do not understand this.  As another example of the
+difference, remember that comments encountered in arguments are passed
+untouched to the macro, and that quoting disables comments.
+
+     define(`echo1', `$*')
+     =>
+     define(`echo2', `$@')
+     =>
+     define(`foo', `bar')
+     =>
+     echo1(#foo'foo
+     foo)
+     =>#foo'foo
+     =>bar
+     echo2(#foo'foo
+     foo)
+     =>#foobar
+     =>bar'
+
+   A '$' sign in the expansion text, that is not followed by anything
+'m4' understands, is simply copied to the macro expansion, as any other
+text is.
+
+     define(`foo', `$$$ hello $$$')
+     =>
+     foo
+     =>$$$ hello $$$
+
+   If you want a macro to expand to something like '$12', the judicious
+use of nested quoting can put a safe character between the '$' and the
+next character, relying on the rescanning to remove the nested quote.
+This will prevent 'm4' from interpreting the '$' sign as a reference to
+an argument.
+
+     define(`foo', `no nested quote: $1')

+5.4 Deleting a macro
+====================
+
+A macro definition can be removed with 'undefine':
+
+ -- Builtin: undefine (NAME...)
+     For each argument, remove the macro NAME.  The macro names must
+     necessarily be quoted, since they will be expanded otherwise.
+
+     The expansion of 'undefine' is void.  The macro 'undefine' is
+     recognized only with parameters.
+
+     foo bar blah
+     =>foo bar blah
+     define(`foo', `some')define(`bar', `other')define(`blah', `text')
+     =>
+     foo bar blah
+     =>some other text
+     undefine(`foo')
+     =>
+     foo bar blah
+     =>foo other text
+     undefine(`bar', `blah')
+     =>
+     foo bar blah
+     =>foo bar blah
+
+   Undefining a macro inside that macro's expansion is safe; the macro
+still expands to the definition that was in effect at the '('.
+
+     define(`f', ``$0':$1')
+     =>
+     f(f(f(undefine(`f')`hello world')))
+     =>f:f:f:hello world
+     f(`bye')
+     =>f(bye)
+
+   It is not an error for NAME to have no macro definition.  In that
+case, 'undefine' does nothing.

+
+5.5 Renaming macros
+===================
+
+It is possible to rename an already defined macro.  To do this, you need
+the builtin 'defn':
+
+ -- Builtin: defn (NAME...)
+     Expands to the _quoted definition_ of each NAME.  If an argument is
+     not a defined macro, the expansion for that argument is empty.
+
+     If NAME is a user-defined macro, the quoted definition is simply
+     the quoted expansion text.  If, instead, there is only one NAME and
+     it is a builtin, the expansion is a special token, which points to
+     the builtin's internal definition.  This token is only meaningful
+     as the second argument to 'define' (and 'pushdef'), and is silently
+     converted to an empty string in most other contexts.  Combining a
+     builtin with anything else is not supported; a warning is issued
+     and the builtin is omitted from the final expansion.
+
+     The macro 'defn' is recognized only with parameters.
+
+   Its normal use is best understood through an example, which shows how
+to rename 'undefine' to 'zap':
+
+     define(`zap', defn(`undefine'))
+     =>
+     zap(`undefine')
+     =>
+     undefine(`zap')
+     =>undefine(zap)
+
+   In this way, 'defn' can be used to copy macro definitions, and also
+definitions of builtin macros.  Even if the original macro is removed,
+the other name can still be used to access the definition.
+
+   The fact that macro definitions can be transferred also explains why
+you should use '$0', rather than retyping a macro's name in its
+definition:
+
+     define(`foo', `This is `$0'')
+     =>
+     define(`bar', defn(`foo'))
+     =>
+     bar
+     =>This is bar
+
+   Macros used as string variables should be referred through 'defn', to
+avoid unwanted expansion of the text:
+
+     define(`string', `The macro dnl is very useful
+     ')
+     =>
+     string
+     =>The macro 
+     defn(`string')
+     =>The macro dnl is very useful
+     =>
+
+   However, it is important to remember that 'm4' rescanning is purely
+textual.  If an unbalanced end-quote string occurs in a macro
+definition, the rescan will see that embedded quote as the termination
+of the quoted string, and the remainder of the macro's definition will
+be rescanned unquoted.  Thus it is a good idea to avoid unbalanced
+end-quotes in macro definitions or arguments to macros.
+
+     define(`foo', a'a)
+     =>
+     define(`a', `A')
+     =>
+     define(`echo', `$@')
+     =>
+     foo
+     =>A'A
+     defn(`foo')
+     =>aA'
+     echo(foo)
+     =>AA'
+
+   On the other hand, it is possible to exploit the fact that 'defn' can
+concatenate multiple macros prior to the rescanning phase, in order to
+join the definitions of macros that, in isolation, have unbalanced
+quotes.  This is particularly useful when one has used several macros to
+accumulate text that M4 should rescan as a whole.  In the example below,
+note how the use of 'defn' on 'l' in isolation opens a string, which is
+not closed until the next line; but used on 'l' and 'r' together results
+in nested quoting.
+
+     define(`l', `<[>')define(`r', `<]>')
+     =>
+     changequote(`[', `]')
+     =>
+     defn([l])defn([r])
+     ])
+     =><[>]defn([r])
+     =>)
+     defn([l], [r])
+     =><[>][<]>
+
+   Using 'defn' to generate special tokens for builtin macros outside of
+expected contexts can sometimes trigger warnings.  But most of the time,
+such tokens are silently converted to the empty string.
+
+     $ m4 -d
+     defn(`defn')
+     =>
+     define(defn(`divnum'), `cannot redefine a builtin token')
+     error->m4:stdin:2: Warning: define: invalid macro name ignored
+     =>
+     divnum
+     =>0
+     len(defn(`divnum'))
+     =>0
+
+   Also note that 'defn' with multiple arguments can only join text
+macros, not builtins, although a future version of GNU M4 may lift this
+restriction.
+
+     $ m4 -d
+     define(`a', `A')define(`AA', `b')
+     =>
+     traceon(`defn', `define')

+
+5.6 Temporarily redefining macros
+=================================
+
+It is possible to redefine a macro temporarily, reverting to the
+previous definition at a later time.  This is done with the builtins
+'pushdef' and 'popdef':
+
+ -- Builtin: pushdef (NAME, [EXPANSION]
+ -- Builtin: popdef (NAME...)
+     Analogous to 'define' and 'undefine'.
+
+     These macros work in a stack-like fashion.  A macro is temporarily
+     redefined with 'pushdef', which replaces an existing definition of
+     NAME, while saving the previous definition, before the new one is
+     installed.  If there is no previous definition, 'pushdef' behaves
+     exactly like 'define'.
+
+     If a macro has several definitions (of which only one is
+     accessible), the topmost definition can be removed with 'popdef'.
+     If there is no previous definition, 'popdef' behaves like
+     'undefine'.
+
+     The expansion of both 'pushdef' and 'popdef' is void.  The macros
+     'pushdef' and 'popdef' are recognized only with parameters.
+
+     define(`foo', `Expansion one.')
+     =>
+     foo
+     =>Expansion one.
+     pushdef(`foo', `Expansion two.')
+     =>
+     foo
+     =>Expansion two.
+     pushdef(`foo', `Expansion three.')
+     =>
+     pushdef(`foo', `Expansion four.')
+     =>
+     popdef(`foo')
+     =>
+     foo
+     =>Expansion three.
+     popdef(`foo', `foo')
+     =>
+     foo
+     =>Expansion one.
+     popdef(`foo')
+     =>
+     foo
+     =>foo
+
+   If a macro with several definitions is redefined with 'define', the
+topmost definition is _replaced_ with the new definition.  If it is
+removed with 'undefine', _all_ the definitions are removed, and not only
+the topmost one.  However, POSIX allows other implementations that treat
+'define' as replacing an entire stack of definitions with a single new
+definition, so to be portable to other implementations, it may be worth
+explicitly using 'popdef' and 'pushdef' rather than relying on the GNU
+behavior of 'define'.
+
+     define(`foo', `Expansion one.')
+     =>
+     foo
+     =>Expansion one.
+     pushdef(`foo', `Expansion two.')
+     =>
+     foo
+     =>Expansion two.
+     define(`foo', `Second expansion two.')
+     =>
+     foo
+     =>Second expansion two.
+     undefine(`foo')
+     =>
+     foo
+     =>foo
+
+   Local variables within macros are made with 'pushdef' and 'popdef'.
+At the start of the macro a new definition is pushed, within the macro
+it is manipulated and at the end it is popped, revealing the former
+definition.
+
+   It is possible to temporarily redefine a builtin with 'pushdef' and
+'defn'.

+5.7 Indirect call of macros
+===========================
+
+Any macro can be called indirectly with 'indir':
+
+ -- Builtin: indir (NAME, [ARGS...]
+     Results in a call to the macro NAME, which is passed the rest of
+     the arguments ARGS.  If NAME is not defined, an error message is
+     printed, and the expansion is void.
+
+     The macro 'indir' is recognized only with parameters.
+
+   This can be used to call macros with computed or "invalid" names
+('define' allows such names to be defined):
+
+     define(`$$internal$macro', `Internal macro (name `$0')')
+     =>
+     $$internal$macro
+     =>$$internal$macro
+     indir(`$$internal$macro')
+     =>Internal macro (name $$internal$macro)
+
+   The point is, here, that larger macro packages can have private
+macros defined, that will not be called by accident.  They can _only_ be
+called through the builtin 'indir'.
+
+   One other point to observe is that argument collection occurs before
+'indir' invokes NAME, so if argument collection changes the value of
+NAME, that will be reflected in the final expansion.  This is different
+than the behavior when invoking macros directly, where the definition
+that was in effect before argument collection is used.
+
+     $ m4 -d
+     define(`f', `1')
+     =>
+     f(define(`f', `2'))

+     =>3
+     indir(`f', undefine(`f'))
+     error->m4:stdin:4: undefined macro `f'
+     =>
+
+   When handed the result of 'defn' (*note Defn::) as one of its
+arguments, 'indir' defers to the invoked NAME for whether a token
+representing a builtin is recognized or flattened to the empty string.

+
+5.8 Indirect call of builtins
+=============================
+
+Builtin macros can be called indirectly with 'builtin':
+
+ -- Builtin: builtin (NAME, [ARGS...]
+     Results in a call to the builtin NAME, which is passed the rest of
+     the arguments ARGS.  If NAME does not name a builtin, an error
+     message is printed, and the expansion is void.
+
+     The macro 'builtin' is recognized only with parameters.
+
+   This can be used even if NAME has been given another definition that
+has covered the original, or been undefined so that no macro maps to the
+builtin.
+
+     pushdef(`define', `hidden')
+     =>
+     undefine(`undefine')
+     =>
+     define(`foo', `bar')
+     =>hidden
+     foo
+     =>foo
+     builtin(`define', `foo', defn(`divnum'))

+     foo
+     =>BAR
+     builtin(`undefine', `foo')
+     =>
+     foo
+     =>foo
+
+   The NAME argument only matches the original name of the builtin, even
+when the '--prefix-builtins' option (or '-P', *note Invoking m4:
+Operation modes.) is in effect.  This is different from 'indir', which
+only tracks current macro names.

+   Note that 'indir' and 'builtin' can be used to invoke builtins
+without arguments, even when they normally require parameters to be
+recognized; but it will provoke a warning, and result in a void

+6 Conditionals, loops, and recursion
+************************************
+
+Macros, expanding to plain text, perhaps with arguments, are not quite
+enough.  We would like to have macros expand to different things, based
+on decisions taken at run-time.  For that, we need some kind of
+conditionals.  Also, we would like to have some kind of loop construct,
+so we could do something a number of times, or while some condition is
+true.

+
+6.1 Testing if a macro is defined
+=================================
+
+There are two different builtin conditionals in 'm4'.  The first is
+'ifdef':
+
+ -- Builtin: ifdef (NAME, STRING-1, [STRING-2]
+     If NAME is defined as a macro, 'ifdef' expands to STRING-1,
+     otherwise to STRING-2.  If STRING-2 is omitted, it is taken to be
+     the empty string (according to the normal rules).
+
+     The macro 'ifdef' is recognized only with parameters.
+
+     ifdef(`foo', ``foo' is defined', ``foo' is not defined')
+     =>foo is not defined
+     define(`foo', `')
+     =>
+     ifdef(`foo', ``foo' is defined', ``foo' is not defined')
+     =>foo is defined
+     ifdef(`no_such_macro', `yes', `no', `extra argument')
+     error->m4:stdin:4: Warning: excess arguments to builtin `ifdef' ignored
+     =>no
+
+
+File: m4.info,  Node: Ifelse,  Next: Shift,  Prev: Ifdef,  Up: Conditionals
+
+6.2 If-else construct, or multibranch
+=====================================
+
+The other conditional, 'ifelse', is much more powerful.  It can be used
+as a way to introduce a long comment, as an if-else construct, or as a
+multibranch, depending on the number of arguments supplied:
+
+ -- Builtin: ifelse (COMMENT)
+ -- Builtin: ifelse (STRING-1, STRING-2, EQUAL, [NOT-EQUAL]
+ -- Builtin: ifelse (STRING-1, STRING-2, EQUAL-1, STRING-3, STRING-4,
+          EQUAL-2, ..., [NOT-EQUAL]
+     Used with only one argument, the 'ifelse' simply discards it and
+     produces no output.
+
+     If called with three or four arguments, 'ifelse' expands into
+     EQUAL, if STRING-1 and STRING-2 are equal (character for
+     character), otherwise it expands to NOT-EQUAL.  A final fifth
+     argument is ignored, after triggering a warning.
+
+     If called with six or more arguments, and STRING-1 and STRING-2 are
+     equal, 'ifelse' expands into EQUAL-1, otherwise the first three
+     arguments are discarded and the processing starts again.
+
+     The macro 'ifelse' is recognized only with parameters.
+
+   Using only one argument is a common 'm4' idiom for introducing a
+block comment, as an alternative to repeatedly using 'dnl'.  This
+special usage is recognized by GNU 'm4', so that in this case, the
+warning about missing arguments is never triggered.
+
+     ifelse(`some comments')
+     =>
+     ifelse(`foo', `bar')
+     error->m4:stdin:2: Warning: too few arguments to builtin `ifelse'
+     =>
+
+   Using three or four arguments provides decision points.
+
+     ifelse(`foo', `bar', `true')
+     =>
+     ifelse(`foo', `foo', `true')
+     =>true
+     define(`foo', `bar')
+     =>
+     ifelse(foo, `bar', `true', `false')
+     =>true
+     ifelse(foo, `foo', `true', `false')
+     =>false
+
+   Notice how the first argument was used unquoted; it is common to
+compare the expansion of a macro with a string.  With this macro, you
+can now reproduce the behavior of blind builtins, where the macro is
+recognized only with arguments.
+
+     define(`foo', `ifelse(`$#', `0', ``$0'', `arguments:$#')')
+     =>
+     foo
+     =>foo
+     foo()
+     =>arguments:1
+     foo(`a', `b', `c')
+     =>arguments:3
+
+   For an example of a way to make defining blind macros easier, see
+*note Composition::.
+
+   The macro 'ifelse' can take more than four arguments.  If given more
+than four arguments, 'ifelse' works like a 'case' or 'switch' statement
+in traditional programming languages.  If STRING-1 and STRING-2 are
+equal, 'ifelse' expands into EQUAL-1, otherwise the procedure is
+repeated with the first three arguments discarded.  This calls for an
+example:
+
+     ifelse(`foo', `bar', `third', `gnu', `gnats')
+     error->m4:stdin:1: Warning: excess arguments to builtin `ifelse' ignored
+     =>gnu
+     ifelse(`foo', `bar', `third', `gnu', `gnats', `sixth')
+     =>
+     ifelse(`foo', `bar', `third', `gnu', `gnats', `sixth', `seventh')
+     =>seventh
+     ifelse(`foo', `bar', `3', `gnu', `gnats', `6', `7', `8')
+     error->m4:stdin:4: Warning: excess arguments to builtin `ifelse' ignored
+     =>7
+
+   Naturally, the normal case will be slightly more advanced than these
+examples.  A common use of 'ifelse' is in macros implementing loops of
+various kinds.

+
+6.3 Recursion in 'm4'
+=====================
+
+There is no direct support for loops in 'm4', but macros can be
+recursive.  There is no limit on the number of recursion levels, other
+than those enforced by your hardware and operating system.
+
+   Loops can be programmed using recursion and the conditionals
+described previously.
+
+   There is a builtin macro, 'shift', which can, among other things, be
+used for iterating through the actual arguments to a macro:
+
+ -- Builtin: shift (ARG1, ...)
+     Takes any number of arguments, and expands to all its arguments
+     except ARG1, separated by commas, with each argument quoted.
+
+     The macro 'shift' is recognized only with parameters.
+
+     shift
+     =>shift
+     shift(`bar')
+     =>
+     shift(`foo', `bar', `baz')
+     =>bar,baz
+
+   An example of the use of 'shift' is this macro:
+
+ -- Composite: reverse (...)
+     Takes any number of arguments, and reverses their order.
+
+   It is implemented as:
+
+     define(`reverse', `ifelse(`$#', `0', , `$#', `1', ``$1'',
+                               `reverse(shift($@)), `$1'')')
+     =>
+     reverse
+     =>
+     reverse(`foo')
+     =>foo
+     reverse(`foo', `bar', `gnats', `and gnus')
+     =>and gnus, gnats, bar, foo
+
+   While not a very interesting macro, it does show how simple loops can
+be made with 'shift', 'ifelse' and recursion.  It also shows that
+'shift' is usually used with '$@'.  Another example of this is an
+implementation of a short-circuiting conditional operator.
+
+ -- Composite: cond (TEST-1, STRING-1, EQUAL-1, [TEST-2]
+     Similar to 'ifelse', where an equal comparison between the first
+     two strings results in the third, otherwise the first three
+     arguments are discarded and the process repeats.  The difference is
+     that each TEST-<N> is expanded only when it is encountered.  This
+     means that every third argument to 'cond' is normally given one
+     more level of quoting than the corresponding argument to 'ifelse'.
+
+   Here is the implementation of 'cond', along with a demonstration of
+how it can short-circuit the side effects in 'side'.  Notice how all the
+unquoted side effects happen regardless of how many comparisons are made
+with 'ifelse', compared with only the relevant effects with 'cond'.
+
+     define(`cond',
+     `ifelse(`$#', `1', `$1',
+             `ifelse($1, `$2', `$3',

+     =>default answer: 4
+
+   Another common task that requires iteration is joining a list of
+arguments into a single string.
+
+ -- Composite: join ([SEPARATOR]
+ -- Composite: joinall ([SEPARATOR]
+     Generate a single-quoted string, consisting of each ARG separated
+     by SEPARATOR.  While 'joinall' always outputs a SEPARATOR between
+     arguments, 'join' avoids the SEPARATOR for an empty ARG.
+
+   Here are some examples of its usage, based on the implementation
+'m4-1.4.17/examples/join.m4' distributed in this package:
+
+     $ m4 -I examples
+     include(`join.m4')
+     =>
+     join,join(`-'),join(`-', `'),join(`-', `', `')
+     =>,,,
+     joinall,joinall(`-'),joinall(`-', `'),joinall(`-', `', `')
+     =>,,,-
+     join(`-', `1')
+     =>1
+     join(`-', `1', `2', `3')
+     =>1-2-3
+     join(`', `1', `2', `3')
+     =>123
+     join(`-', `', `1', `', `', `2', `')
+     =>1-2
+     joinall(`-', `', `1', `', `', `2', `')
+     =>-1---2-
+     join(`,', `1', `2', `3')
+     =>1,2,3
+     define(`nargs', `$#')dnl
+     nargs(join(`,', `1', `2', `3'))
+     =>1
+
+   Examining the implementation shows some interesting points about
+several m4 programming idioms.
+
+     $ m4 -I examples
+     undivert(`join.m4')dnl
+     =>divert(`-1')
+     =># join(sep, args) - join each non-empty ARG into a single
+     =># string, with each element separated by SEP
+     =>define(`join',
+     =>`ifelse(`$#', `2', ``$2'',
+     =>  `ifelse(`$2', `', `', ``$2'_')$0(`$1', shift(shift($@)))')')
+     =>define(`_join',
+     =>`ifelse(`$#$2', `2', `',
+     =>  `ifelse(`$2', `', `', ``$1$2'')$0(`$1', shift(shift($@)))')')
+     =># joinall(sep, args) - join each ARG, including empty ones,
+     =># into a single string, with each element separated by SEP
+     =>define(`joinall', ``$2'_$0(`$1', shift($@))')
+     =>define(`_joinall',
+     =>`ifelse(`$#', `2', `', ``$1$3'$0(`$1', shift(shift($@)))')')
+     =>divert`'dnl
+
+   First, notice that this implementation creates helper macros '_join'
+and '_joinall'.  This division of labor makes it easier to output the
+correct number of SEPARATOR instances: 'join' and 'joinall' are
+responsible for the first argument, without a separator, while '_join'
+and '_joinall' are responsible for all remaining arguments, always
+outputting a separator when outputting an argument.
+
+   Next, observe how 'join' decides to iterate to itself, because the
+first ARG was empty, or to output the argument and swap over to '_join'.
+If the argument is non-empty, then the nested 'ifelse' results in an
+unquoted '_', which is concatenated with the '$0' to form the next macro
+name to invoke.  The 'joinall' implementation is simpler since it does
+not have to suppress empty ARG; it always executes once then defers to
+'_joinall'.
+
+   Another important idiom is the idea that SEPARATOR is reused for each
+iteration.  Each iteration has one less argument, but rather than
+discarding '$1' by iterating with '$0(shift($@))', the macro discards
+'$2' by using '$0(`$1', shift(shift($@)))'.
+
+   Next, notice that it is possible to compare more than one condition
+in a single 'ifelse' test.  The test of '$#$2' against '2' allows
+'_join' to iterate for two separate reasons--either there are still more
+than two arguments, or there are exactly two arguments but the last
+argument is not empty.
+
+   Finally, notice that these macros require exactly two arguments to
+terminate recursion, but that they still correctly result in empty
+output when given no ARGS (i.e., zero or one macro argument).  On the
+first pass when there are too few arguments, the 'shift' results in no
+output, but leaves an empty string to serve as the required second
+argument for the second pass.  Put another way, '`$1', shift($@)' is not
+the same as '$@', since only the former guarantees at least two
+arguments.
+
+   Sometimes, a recursive algorithm requires adding quotes to each
+element, or treating multiple arguments as a single element:
+
+ -- Composite: quote (...)
+ -- Composite: dquote (...)
+ -- Composite: dquote_elt (...)
+     Takes any number of arguments, and adds quoting.  With 'quote',
+     only one level of quoting is added, effectively removing whitespace
+     after commas and turning multiple arguments into a single string.
+     With 'dquote', two levels of quoting are added, one around each
+     element, and one around the list.  And with 'dquote_elt', two
+     levels of quoting are added around each element.
+
+   An actual implementation of these three macros is distributed as
+'m4-1.4.17/examples/quote.m4' in this package.  First, let's examine
+their usage:
+
+     $ m4 -I examples
+     include(`quote.m4')
+     =>
+     -quote-dquote-dquote_elt-
+     =>----
+     -quote()-dquote()-dquote_elt()-
+     =>--`'-`'-
+     -quote(`1')-dquote(`1')-dquote_elt(`1')-
+     =>-1-`1'-`1'-
+     -quote(`1', `2')-dquote(`1', `2')-dquote_elt(`1', `2')-
+     =>-1,2-`1',`2'-`1',`2'-
+     define(`n', `$#')dnl
+     -n(quote(`1', `2'))-n(dquote(`1', `2'))-n(dquote_elt(`1', `2'))-
+     =>-1-1-2-
+     dquote(dquote_elt(`1', `2'))
+     =>``1'',``2''
+     dquote_elt(dquote(`1', `2'))
+     =>``1',`2''
+
+   The last two lines show that when given two arguments, 'dquote'
+results in one string, while 'dquote_elt' results in two.  Now, examine
+the implementation.  Note that 'quote' and 'dquote_elt' make decisions
+based on their number of arguments, so that when called without
+arguments, they result in nothing instead of a quoted empty string; this
+is so that it is possible to distinguish between no arguments and an
+empty first argument.  'dquote', on the other hand, results in a string
+no matter what, since it is still possible to tell whether it was
+invoked without arguments based on the resulting string.
+
+     $ m4 -I examples
+     undivert(`quote.m4')dnl
+     =>divert(`-1')
+     =># quote(args) - convert args to single-quoted string
+     =>define(`quote', `ifelse(`$#', `0', `', ``$*'')')
+     =># dquote(args) - convert args to quoted list of quoted strings
+     =>define(`dquote', ``$@'')

+     =>divert`'dnl
+
+   It is worth pointing out that 'quote(ARGS)' is more efficient than
+'joinall(`,', ARGS)' for producing the same output.
+
+   One more useful macro based on 'shift' allows portably selecting an
+arbitrary argument (usually greater than the ninth argument), without
+relying on the GNU extension of multi-digit arguments (*note
+Arguments::).
+
+ -- Composite: argn (N, ...)
+     Expands to argument N out of the remaining arguments.  N must be a
+     positive number.  Usually invoked as 'argn(`N',$@)'.
+
+   It is implemented as:
+
+     define(`argn', `ifelse(`$1', 1, ``$2'',
+       `argn(decr(`$1'), shift(shift($@)))')')
+     =>
+     argn(`1', `a')
+     =>a
+     define(`foo', `argn(`11', $@)')
+     =>
+     foo(`a', `b', `c', `d', `e', `f', `g', `h', `i', `j', `k', `l')
+     =>k

+
+6.4 Iteration by counting
+=========================
+
+Here is an example of a loop macro that implements a simple for loop.
+
+ -- Composite: forloop (ITERATOR, START, END, TEXT)
+     Takes the name in ITERATOR, which must be a valid macro name, and
+     successively assign it each integer value from START to END,
+     inclusive.  For each assignment to ITERATOR, append TEXT to the
+     expansion of the 'forloop'.  TEXT may refer to ITERATOR.  Any
+     definition of ITERATOR prior to this invocation is restored.
+
+   It can, for example, be used for simple counting:
+
+     $ m4 -I examples
+     include(`forloop.m4')
+     =>
+     forloop(`i', `1', `8', `i ')
+     =>1 2 3 4 5 6 7 8 
+
+   For-loops can be nested, like:
+
+     $ m4 -I examples
+     include(`forloop.m4')
+     =>
+     forloop(`i', `1', `4', `forloop(`j', `1', `8', ` (i, j)')
+     ')
+     => (1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6) (1, 7) (1, 8)
+     => (2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6) (2, 7) (2, 8)
+     => (3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6) (3, 7) (3, 8)
+     => (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6) (4, 7) (4, 8)
+     =>
+
+   The implementation of the 'forloop' macro is fairly straightforward.
+The 'forloop' macro itself is simply a wrapper, which saves the previous
+definition of the first argument, calls the internal macro '_forloop',
+and re-establishes the saved definition of the first argument.
+
+   The macro '_forloop' expands the fourth argument once, and tests to
+see if the iterator has reached the final value.  If it has not
+finished, it increments the iterator (using the predefined macro 'incr',
+*note Incr::), and recurses.
+
+   Here is an actual implementation of 'forloop', distributed as
+'m4-1.4.17/examples/forloop.m4' in this package:
+
+     $ m4 -I examples
+     undivert(`forloop.m4')dnl
+     =>divert(`-1')
+     =># forloop(var, from, to, stmt) - simple version
+     =>define(`forloop', `pushdef(`$1', `$2')_forloop($@)popdef(`$1')')
+     =>define(`_forloop',
+     =>       `$4`'ifelse($1, `$3', `', `define(`$1', incr($1))$0($@)')')
+     =>divert`'dnl
+
+   Notice the careful use of quotes.  Certain macro arguments are left
+unquoted, each for its own reason.  Try to find out _why_ these
+arguments are left unquoted, and see what happens if they are quoted.
+(As presented, these two macros are useful but not very robust for
+general use.  They lack even basic error handling for cases like START
+less than END, END not numeric, or ITERATOR not being a macro name.  See
+if you can improve these macros; or *note Answers: Improved forloop.).

+
+6.5 Iteration by list contents
+==============================
+
+Here is an example of a loop macro that implements list iteration.
+
+ -- Composite: foreach (ITERATOR, PAREN-LIST, TEXT)
+ -- Composite: foreachq (ITERATOR, QUOTE-LIST, TEXT)
+     Takes the name in ITERATOR, which must be a valid macro name, and
+     successively assign it each value from PAREN-LIST or QUOTE-LIST.
+     In 'foreach', PAREN-LIST is a comma-separated list of elements
+     contained in parentheses.  In 'foreachq', QUOTE-LIST is a
+     comma-separated list of elements contained in a quoted string.  For
+     each assignment to ITERATOR, append TEXT to the overall expansion.
+     TEXT may refer to ITERATOR.  Any definition of ITERATOR prior to
+     this invocation is restored.
+
+   As an example, this displays each word in a list inside of a
+sentence, using an implementation of 'foreach' distributed as
+'m4-1.4.17/examples/foreach.m4', and 'foreachq' in
+'m4-1.4.17/examples/foreachq.m4'.
+
+     $ m4 -I examples
+     include(`foreach.m4')
+     =>
+     foreach(`x', (foo, bar, foobar), `Word was: x
+     ')dnl
+     =>Word was: foo
+     =>Word was: bar
+     =>Word was: foobar
+     include(`foreachq.m4')
+     =>
+     foreachq(`x', `foo, bar, foobar', `Word was: x
+     ')dnl
+     =>Word was: foo
+     =>Word was: bar
+     =>Word was: foobar
+
+   It is possible to be more complex; each element of the PAREN-LIST or
+QUOTE-LIST can itself be a list, to pass as further arguments to a
+helper macro.  This example generates a shell case statement:
+
+     $ m4 -I examples
+     include(`foreach.m4')
+     =>
+     define(`_case', `  $1)
+         $2=" $1";;
+     ')dnl
+     define(`_cat', `$1$2')dnl
+     case $`'1 in
+     =>case $1 in
+     foreach(`x', `(`(`a', `vara')', `(`b', `varb')', `(`c', `varc')')',
+             `_cat(`_case', x)')dnl
+     =>  a)
+     =>    vara=" a";;
+     =>  b)
+     =>    varb=" b";;
+     =>  c)
+     =>    varc=" c";;
+     esac
+     =>esac
+
+   The implementation of the 'foreach' macro is a bit more involved; it
+is a wrapper around two helper macros.  First, '_arg1' is needed to grab
+the first element of a list.  Second, '_foreach' implements the
+recursion, successively walking through the original list.  Here is a
+simple implementation of 'foreach':
+
+     $ m4 -I examples
+     undivert(`foreach.m4')dnl
+     =>divert(`-1')
+     =># foreach(x, (item_1, item_2, ..., item_n), stmt)
+     =>#   parenthesized list, simple version
+     =>define(`foreach', `pushdef(`$1')_foreach($@)popdef(`$1')')
+     =>define(`_arg1', `$1')
+     =>define(`_foreach', `ifelse(`$2', `()', `',
+     =>  `define(`$1', _arg1$2)$3`'$0(`$1', (shift$2), `$3')')')
+     =>divert`'dnl
+
+   Unfortunately, that implementation is not robust to macro names as
+list elements.  Each iteration of '_foreach' is stripping another layer
+of quotes, leading to erratic results if list elements are not already
+fully expanded.  The first cut at implementing 'foreachq' takes this
+into account.  Also, when using quoted elements in a PAREN-LIST, the
+overall list must be quoted.  A QUOTE-LIST has the nice property of
+requiring fewer characters to create a list containing the same quoted
+elements.  To see the difference between the two macros, we attempt to
+pass double-quoted macro names in a list, expecting the macro name on
+output after one layer of quotes is removed during list iteration and
+the final layer removed during the final rescan:
+
+     $ m4 -I examples
+     define(`a', `1')define(`b', `2')define(`c', `3')
+     =>
+     include(`foreach.m4')
+     =>
+     include(`foreachq.m4')
+     =>
+     foreach(`x', `(``a'', ``(b'', ``c)'')', `x
+     ')
+     =>1
+     =>(2)1
+     =>
+     =>, x
+     =>)
+     foreachq(`x', ```a'', ``(b'', ``c)''', `x
+     ')dnl
+     =>a
+     =>(b
+     =>c)
+
+   Obviously, 'foreachq' did a better job; here is its implementation:
+
+     $ m4 -I examples
+     undivert(`foreachq.m4')dnl
+     =>include(`quote.m4')dnl
+     =>divert(`-1')
+     =># foreachq(x, `item_1, item_2, ..., item_n', stmt)
+     =>#   quoted list, simple version
+     =>define(`foreachq', `pushdef(`$1')_foreachq($@)popdef(`$1')')
+     =>define(`_arg1', `$1')
+     =>define(`_foreachq', `ifelse(quote($2), `', `',
+     =>  `define(`$1', `_arg1($2)')$3`'$0(`$1', `shift($2)', `$3')')')
+     =>divert`'dnl
+
+   Notice that '_foreachq' had to use the helper macro 'quote' defined
+earlier (*note Shift::), to ensure that the embedded 'ifelse' call does
+not go haywire if a list element contains a comma.  Unfortunately, this
+implementation of 'foreachq' has its own severe flaw.  Whereas the
+'foreach' implementation was linear, this macro is quadratic in the
+number of list elements, and is much more likely to trip up the limit
+set by the command line option '--nesting-limit' (or '-L', *note
+Invoking m4: Limits control.).  Additionally, this implementation does
+not expand 'defn(`ITERATOR')' very well, when compared with 'foreach'.
+
+     $ m4 -I examples
+     include(`foreach.m4')include(`foreachq.m4')
+     =>
+     foreach(`name', `(`a', `b')', ` defn(`name')')
+     => a b
+     foreachq(`name', ``a', `b'', ` defn(`name')')
+     => _arg1(`a', `b') _arg1(shift(`a', `b'))
+
+   It is possible to have robust iteration with linear behavior and sane
+ITERATOR contents for either list style.  See if you can learn from the
+best elements of both of these implementations to create robust macros
+(or *note Answers: Improved foreach.).

+
+6.6 Working with definition stacks
+==================================
+
+Thanks to 'pushdef', manipulation of a stack is an intrinsic operation
+in 'm4'.  Normally, only the topmost definition in a stack is important,
+but sometimes, it is desirable to manipulate the entire definition
+stack.
+
+ -- Composite: stack_foreach (MACRO, ACTION)
+ -- Composite: stack_foreach_lifo (MACRO, ACTION)
+     For each of the 'pushdef' definitions associated with MACRO, invoke
+     the macro ACTION with a single argument of that definition.
+     'stack_foreach' visits the oldest definition first, while
+     'stack_foreach_lifo' visits the current definition first.  ACTION
+     should not modify or dereference MACRO.  There are a few special
+     macros, such as 'defn', which cannot be used as the MACRO
+     parameter.
+
+   A sample implementation of these macros is distributed in the file
+'m4-1.4.17/examples/stack.m4'.
+
+     $ m4 -I examples
+     include(`stack.m4')
+     =>
+     pushdef(`a', `1')pushdef(`a', `2')pushdef(`a', `3')
+     =>
+     define(`show', ``$1'
+     ')
+     =>
+     stack_foreach(`a', `show')dnl
+     =>1
+     =>2
+     =>3
+     stack_foreach_lifo(`a', `show')dnl
+     =>3
+     =>2
+     =>1
+
+   Now for the implementation.  Note the definition of a helper macro,
+'_stack_reverse', which destructively swaps the contents of one stack of
+definitions into the reverse order in the temporary macro 'tmp-$1'.  By
+calling the helper twice, the original order is restored back into the
+macro '$1'; since the operation is destructive, this explains why '$1'
+must not be modified or dereferenced during the traversal.  The caller
+can then inject additional code to pass the definition currently being
+visited to '$2'.  The choice of helper names is intentional; since '-'
+is not valid as part of a macro name, there is no risk of conflict with
+a valid macro name, and the code is guaranteed to use 'defn' where
+necessary.  Finally, note that any macro used in the traversal of a
+'pushdef' stack, such as 'pushdef' or 'defn', cannot be handled by
+'stack_foreach', since the macro would temporarily be undefined during
+the algorithm.

+6.7 Building macros with macros
+===============================
+
+Since m4 is a macro language, it is possible to write macros that can
+build other macros.  First on the list is a way to automate the creation
+of blind macros.
+
+ -- Composite: define_blind (NAME, [VALUE]
+     Defines NAME as a blind macro, such that NAME will expand to VALUE
+     only when given explicit arguments.  VALUE should not be the result
+     of 'defn' (*note Defn::).  This macro is only recognized with
+     parameters, and results in an empty string.
+
+   Defining a macro to define another macro can be a bit tricky.  We
+want to use a literal '$#' in the argument to the nested 'define'.
+However, if '$' and '#' are adjacent in the definition of
+'define_blind', then it would be expanded as the number of arguments to
+'define_blind' rather than the intended number of arguments to NAME.
+The solution is to pass the difficult characters through extra arguments
+to a helper macro '_define_blind'.  When composing macros, it is a
+common idiom to need a helper macro to concatenate text that forms
+parameters in the composed macro, rather than interpreting the text as a
+parameter of the composing macro.
+
+   As for the limitation against using 'defn', there are two reasons.
+If a macro was previously defined with 'define_blind', then it can
+safely be renamed to a new blind macro using plain 'define'; using
+'define_blind' to rename it just adds another layer of 'ifelse',
+occupying memory and slowing down execution.  And if a macro is a
+builtin, then it would result in an attempt to define a macro consisting
+of both text and a builtin token; this is not supported, and the builtin
+token is flattened to an empty string.
+
+   With that explanation, here's the definition, and some sample usage.
+Notice that 'define_blind' is itself a blind macro.
+
+     $ m4 -d
+     define(`define_blind', `ifelse(`$#', `0', ``$0'',
+     `_$0(`$1', `$2', `$'`#', `$'`0')')')
+     =>
+     define(`_define_blind', `define(`$1',
+     `ifelse(`$3', `0', ``$4'', `$2')')')
+     =>
+     define_blind
+     =>define_blind
+     define_blind(`foo', `arguments were $*')
+     =>
+     foo
+     =>foo
+     foo(`bar')
+     =>arguments were bar
+     define(`blah', defn(`foo'))
+     =>
+     blah
+     =>blah
+     blah(`a', `b')
+     =>arguments were a,b
+     defn(`blah')
+     =>ifelse(`$#', `0', ``$0'', `arguments were $*')
+
+   Another interesting composition tactic is argument "currying", or
+factoring a macro that takes multiple arguments for use in a context
+that provides exactly one argument.
+
+ -- Composite: curry (MACRO, ...)
+     Expand to a macro call that takes exactly one argument, then
+     appends that argument to the original arguments and invokes MACRO
+     with the resulting list of arguments.
+
+   A demonstration of currying makes the intent of this macro a little
+more obvious.  The macro 'stack_foreach' mentioned earlier is an example
+of a context that provides exactly one argument to a macro name.  But
+coupled with currying, we can invoke 'reverse' with two arguments for
+each definition of a macro stack.  This example uses the file
+'m4-1.4.17/examples/curry.m4' included in the distribution.
+
+     $ m4 -I examples
+     include(`curry.m4')include(`stack.m4')
+     =>
+     define(`reverse', `ifelse(`$#', `0', , `$#', `1', ``$1'',
+                               `reverse(shift($@)), `$1'')')
+     =>
+     pushdef(`a', `1')pushdef(`a', `2')pushdef(`a', `3')
+     =>
+     stack_foreach(`a', `:curry(`reverse', `4')')
+     =>:1, 4:2, 4:3, 4
+     curry(`curry', `reverse', `1')(`2')(`3')
+     =>3, 2, 1
+
+   Now for the implementation.  Notice how 'curry' leaves off with a
+macro name but no open parenthesis, while still in the middle of
+collecting arguments for '$1'.  The macro '_curry' is the helper macro
+that takes one argument, then adds it to the list and finally supplies
+the closing parenthesis.  The use of a comma inside the 'shift' call
+allows currying to also work for a macro that takes one argument,
+although it often makes more sense to invoke that macro directly rather
+than going through 'curry'.
+
+     $ m4 -I examples
+     undivert(`curry.m4')dnl
+     =>divert(`-1')
+     =># curry(macro, args)
+     =># Expand to a macro call that takes one argument, then invoke
+     =># macro(args, extra).
+     =>define(`curry', `$1(shift($@,)_$0')
+     =>define(`_curry', ``$1')')
+     =>divert`'dnl
+
+   Unfortunately, with M4 1.4.x, 'curry' is unable to handle builtin
+tokens, which are silently flattened to the empty string when passed
+through another text macro.  This limitation will be lifted in a future
+release of M4.
+
+   Putting the last few concepts together, it is possible to copy or
+rename an entire stack of macro definitions.
+
+ -- Composite: copy (SOURCE, DEST)
+ -- Composite: rename (SOURCE, DEST)
+     Ensure that DEST is undefined, then define it to the same stack of
+     definitions currently in SOURCE.  'copy' leaves SOURCE unchanged,
+     while 'rename' undefines SOURCE.  There are only a few macros, such
+     as 'copy' or 'defn', which cannot be copied via this macro.
+
+   The implementation is relatively straightforward (although since it
+uses 'curry', it is unable to copy builtin macros, such as the second
+definition of 'a' as a synonym for 'divnum'.  See if you can design a
+version that works around this limitation, or *note Answers: Improved
+copy.).
+
+     $ m4 -I examples
+     include(`curry.m4')include(`stack.m4')
+     =>
+     define(`rename', `copy($@)undefine(`$1')')dnl
+     define(`copy', `ifdef(`$2', `errprint(`$2 already defined
+     ')m4exit(`1')',
+        `stack_foreach(`$1', `curry(`pushdef', `$2')')')')dnl
+     pushdef(`a', `1')pushdef(`a', defn(`divnum'))pushdef(`a', `2')
+     =>
+     copy(`a', `b')
+     =>

+7 How to debug macros and input
+*******************************
+
+When writing macros for 'm4', they often do not work as intended on the
+first try (as is the case with most programming languages).
+Fortunately, there is support for macro debugging in 'm4'.
+
+* Menu:
+
+* Dumpdef::                     Displaying macro definitions
+* Trace::                       Tracing macro calls
+* Debug Levels::                Controlling debugging output
+* Debug Output::                Saving debugging output
+
+
+File: m4.info,  Node: Dumpdef,  Next: Trace,  Up: Debugging
+
+7.1 Displaying macro definitions
+================================
+
+If you want to see what a name expands into, you can use the builtin
+'dumpdef':
+
+ -- Builtin: dumpdef ([NAMES...]
+     Accepts any number of arguments.  If called without any arguments,
+     it displays the definitions of all known names, otherwise it
+     displays the definitions of the NAMES given.  The output is printed
+     to the current debug file (usually standard error), and is sorted
+     by name.  If an unknown name is encountered, a warning is printed.
+
+     The expansion of 'dumpdef' is void.
+
+     $ m4 -d
+     define(`foo', `Hello world.')
+     =>
+     dumpdef(`foo')
+     error->foo: =>
+     dumpdef(`define')
+     error->define: =>
+
+   The last example shows how builtin macros definitions are displayed.
+The definition that is dumped corresponds to what would occur if the
+macro were to be called at that point, even if other definitions are
+still live due to redefining a macro during argument collection.
+
+     $ m4 -d
+     pushdef(`f', ``$0'1')pushdef(`f', ``$0'2')
+     =>
+     f(popdef(`f')dumpdef(`f'))
+     error->f: =>f2
+     f(popdef(`f')dumpdef(`f'))
+     error->m4:stdin:3: undefined macro `f'
+     =>f1
+
+   *Note Debug Levels::, for information on controlling the details of
+the display.

+File: m4.info,  Node: Trace,  Next: Debug Levels,  Prev: Dumpdef,  Up: Debugging
+
+7.2 Tracing macro calls
+=======================
+
+It is possible to trace macro calls and expansions through the builtins
+'traceon' and 'traceoff':
+
+ -- Builtin: traceon ([NAMES...]
+ -- Builtin: traceoff ([NAMES...]
+     When called without any arguments, 'traceon' and 'traceoff' will
+     turn tracing on and off, respectively, for all currently defined
+     macros.
+
+     When called with arguments, only the macros listed in NAMES are
+     affected, whether or not they are currently defined.
+
+     The expansion of 'traceon' and 'traceoff' is void.
+
+   Whenever a traced macro is called and the arguments have been
+collected, the call is displayed.  If the expansion of the macro call is
+not void, the expansion can be displayed after the call.  The output is
+printed to the current debug file (defaulting to standard error, *note
+Debug Output::).
+
+     $ m4 -d
+     define(`foo', `Hello World.')
+     =>
+     define(`echo', `$@')
+     =>
+     traceon(`foo', `echo')
+     =>
+     foo
+     error->m4trace: -1- foo -> `Hello World.'
+     =>Hello World.
+     echo(`gnus', `and gnats')
+     error->m4trace: -1- echo(`gnus', `and gnats') -> ``gnus',`and gnats''
+     =>gnus,and gnats
+
+   The number between dashes is the depth of the expansion.  It is one
+most of the time, signifying an expansion at the outermost level, but it
+increases when macro arguments contain unquoted macro calls.  The
+maximum number that will appear between dashes is controlled by the
+option '--nesting-limit' (or '-L', *note Invoking m4: Limits control.).
+Additionally, the option '--trace' (or '-t') can be used to invoke
+'traceon(NAME)' before parsing input.
+
+     $ m4 -L 3 -t ifelse
+     ifelse(`one level')
+     error->m4trace: -1- ifelse
+     =>
+     ifelse(ifelse(ifelse(`three levels')))
+     error->m4trace: -3- ifelse
+     error->m4trace: -2- ifelse
+     error->m4trace: -1- ifelse
+     =>
+     ifelse(ifelse(ifelse(ifelse(`four levels'))))
+     error->m4:stdin:3: recursion limit of 3 exceeded, use -L<N> to change it
+
+   Tracing by name is an attribute that is preserved whether the macro
+is defined or not.  This allows the selection of macros to trace before
+those macros are defined.
+
+     $ m4 -d
+     traceoff(`foo')
+     =>
+     traceon(`foo')
+     =>
+     foo
+     =>foo
+     defn(`foo')
+     =>
+     define(`foo', `bar')
+     =>
+     foo
+     error->m4trace: -1- foo -> `bar'
+     =>bar
+     undefine(`foo')
+     =>
+     ifdef(`foo', `yes', `no')
+     =>no
+     indir(`foo')
+     error->m4:stdin:9: undefined macro `foo'
+     =>
+     define(`foo', `blah')
+     =>
+     foo
+     error->m4trace: -1- foo -> `blah'
+     =>blah
+     traceoff
+     =>
+     foo
+     =>blah
+
+   Tracing even works on builtins.  However, 'defn' (*note Defn::) does
+not transfer tracing status.
+
+     $ m4 -d
+     traceon(`traceon')
+     =>
+     traceon(`traceoff')
+     error->m4trace: -1- traceon(`traceoff')
+     =>
+     traceoff(`traceoff')
+     error->m4trace: -1- traceoff(`traceoff')
+     =>
+     traceoff(`traceon')
+     =>
+     traceon(`eval', `m4_divnum')
+     =>
+     define(`m4_eval', defn(`eval'))
+     =>
+     define(`m4_divnum', defn(`divnum'))
+     =>
+     eval(divnum)
+     error->m4trace: -1- eval(`0') -> `0'
+     =>0
+     m4_eval(m4_divnum)
+     error->m4trace: -2- m4_divnum -> `0'
+     =>0

+   *Note Debug Levels::, for information on controlling the details of
+the display.  The format of the trace output is not specified by POSIX,
+and varies between implementations of 'm4'.
+
+
+File: m4.info,  Node: Debug Levels,  Next: Debug Output,  Prev: Trace,  Up: Debugging
+
+7.3 Controlling debugging output
+================================
+
+The '-d' option to 'm4' (or '--debug', *note Invoking m4: Debugging
+options.) controls the amount of details presented in three categories
+of output.  Trace output is requested by 'traceon' (*note Trace::), and
+each line is prefixed by 'm4trace:' in relation to a macro invocation.
+Debug output tracks useful events not associated with a macro
+invocation, and each line is prefixed by 'm4debug:'.  Finally, 'dumpdef'
+(*note Dumpdef::) output is affected, with no prefix added to the output
+lines.
+
+   The FLAGS following the option can be one or more of the following:
+
+'a'
+     In trace output, show the actual arguments that were collected
+     before invoking the macro.  This applies to all macro calls if the
+     't' flag is used, otherwise only the macros covered by calls of
+     'traceon'.  Arguments are subject to length truncation specified by
+     the command line option '--arglength' (or '-l').
+
+'c'
+     In trace output, show several trace lines for each macro call.  A
+     line is shown when the macro is seen, but before the arguments are
+     collected; a second line when the arguments have been collected and
+     a third line after the call has completed.
+
+'e'
+     In trace output, show the expansion of each macro call, if it is
+     not void.  This applies to all macro calls if the 't' flag is used,
+     otherwise only the macros covered by calls of 'traceon'.  The
+     expansion is subject to length truncation specified by the command
+     line option '--arglength' (or '-l').
+
+'f'
+     In debug and trace output, include the name of the current input
+     file in the output line.
+
+'i'
+     In debug output, print a message each time the current input file
+     is changed.
+
+'l'
+     In debug and trace output, include the current input line number in
+     the output line.
+
+'p'
+     In debug output, print a message when a named file is found through
+     the path search mechanism (*note Search Path::), giving the actual
+     file name used.
+
+'q'
+     In trace and dumpdef output, quote actual arguments and macro
+     expansions in the display with the current quotes.  This is useful
+     in connection with the 'a' and 'e' flags above.
+
+'t'
+     In trace output, trace all macro calls made in this invocation of
+     'm4', regardless of the settings of 'traceon'.
+
+'x'
+     In trace output, add a unique 'macro call id' to each line of the
+     trace output.  This is useful in connection with the 'c' flag
+     above.
+
+'V'
+     A shorthand for all of the above flags.
+
+   If no flags are specified with the '-d' option, the default is 'aeq'.
+The examples throughout this manual assume the default flags.
+
+   There is a builtin macro 'debugmode', which allows on-the-fly control
+of the debugging output format:
+
+ -- Builtin: debugmode ([FLAGS]
+     The argument FLAGS should be a subset of the letters listed above.
+     As special cases, if the argument starts with a '+', the flags are
+     added to the current debug flags, and if it starts with a '-', they
+     are removed.  If no argument is present, all debugging flags are
+     cleared (as if no '-d' was given), and with an empty argument the
+     flags are reset to the default of 'aeq'.
+
+     The expansion of 'debugmode' is void.
+
+     $ m4
+     define(`foo', `FOO')
+     =>
+     traceon(`foo')
+     =>
+     debugmode()
+     =>
+     foo
+     error->m4trace: -1- foo -> `FOO'
+     =>FOO
+     debugmode
+     =>
+     foo
+     error->m4trace: -1- foo

+     debugmode(`+l')
+     =>
+     foo
+     error->m4trace:8: -1- foo
+     =>FOO
+
+   The following example demonstrates the behavior of length truncation,
+when specified on the command line.  Note that each argument and the
+final result are individually truncated.  Also, the special tokens for
+builtin functions are not truncated.
+
+     $ m4 -d -l 6
+     define(`echo', `$@')debugmode(`+t')
+     =>
+     echo(`1', `long string')

+     error->m4trace: -2- defn(`change...')
+     error->m4trace: -1- indir(`echo', <changequote>) -> ``''
+     =>
+
+   This example shows the effects of the debug flags that are not
+related to macro tracing.

+7.4 Saving debugging output
+===========================
+
+Debug and tracing output can be redirected to files using either the
+'--debugfile' option to 'm4' (*note Invoking m4: Debugging options.), or
+with the builtin macro 'debugfile':
+
+ -- Builtin: debugfile ([FILE]
+     Sends all further debug and trace output to FILE, opened in append
+     mode.  If FILE is the empty string, debug and trace output are
+     discarded.  If 'debugfile' is called without any arguments, debug
+     and trace output are sent to standard error.  This does not affect
+     warnings, error messages, or 'errprint' output, which are always
+     sent to standard error.  If FILE cannot be opened, the current
+     debug file is unchanged, and an error is issued.
+
+     The expansion of 'debugfile' is void.

+
+8.1 Deleting whitespace in input
+================================
+
+The builtin 'dnl' stands for "Discard to Next Line":
+
+ -- Builtin: dnl
+     All characters, up to and including the next newline, are discarded
+     without performing any macro expansion.  A warning is issued if the
+     end of the file is encountered without a newline.
+
+     The expansion of 'dnl' is void.
+
+   It is often used in connection with 'define', to remove the newline
+that follows the call to 'define'.  Thus
+
+     define(`foo', `Macro `foo'.')dnl A very simple macro, indeed.
+     foo
+     =>Macro foo.
+
+   The input up to and including the next newline is discarded, as
+opposed to the way comments are treated (*note Comments::).
+
+   Usually, 'dnl' is immediately followed by an end of line or some
+other whitespace.  GNU 'm4' will produce a warning diagnostic if 'dnl'
+is followed by an open parenthesis.  In this case, 'dnl' will collect
+and process all arguments, looking for a matching close parenthesis.
+All predictable side effects resulting from this collection will take
+place.  'dnl' will return no output.  The input following the matching
+close parenthesis up to and including the next newline, on whatever line
+containing it, will still be discarded.

+     dnl(`args are ignored, but side effects occur',

+   If the end of file is encountered without a newline character, a
+warning is issued and dnl stops consuming input.

+
+8.2 Changing the quote characters
+=================================
+
+The default quote delimiters can be changed with the builtin
+'changequote':
+
+ -- Builtin: changequote ([START = '`']
+     This sets START as the new begin-quote delimiter and END as the new
+     end-quote delimiter.  If both arguments are missing, the default
+     quotes ('`' and ''') are used.  If START is void, then quoting is
+     disabled.  Otherwise, if END is missing or void, the default
+     end-quote delimiter (''') is used.  The quote delimiters can be of
+     any length.
+
+     The expansion of 'changequote' is void.
+
+     changequote(`[', `]')
+     =>
+     define([foo], [Macro [foo].])
+     =>
+     foo
+     =>Macro foo.
+
+   The quotation strings can safely contain eight-bit characters.  If no
+single character is appropriate, START and END can be of any length.
+Other implementations cap the delimiter length to five characters, but
+GNU has no inherent limit.

+     =>
+     define([[[foo]]], [[[Macro [[[[[foo]]]]].]]])
+     =>
+     foo
+     =>Macro [[foo]].
+
+   Calling 'changequote' with START as the empty string will effectively
+disable the quoting mechanism, leaving no way to quote text.  However,
+using an empty string is not portable, as some other implementations of
+'m4' revert to the default quoting, while others preserve the prior
+non-empty delimiter.  If START is not empty, then an empty END will use
+the default end-quote delimiter of ''', as otherwise, it would be
+impossible to end a quoted string.  Again, this is not portable, as some
+other 'm4' implementations reuse START as the end-quote delimiter, while
+others preserve the previous non-empty value.  Omitting both arguments
+restores the default begin-quote and end-quote delimiters; fortunately
+this behavior is portable to all implementations of 'm4'.
+
+     define(`foo', `Macro `FOO'.')
+     =>
+     changequote(`', `')
+     =>
+     foo
+     =>Macro `FOO'.
+     `foo'
+     =>`Macro `FOO'.'
+     changequote(`,)
+     =>
+     foo
+     =>Macro FOO.
+
+   There is no way in 'm4' to quote a string containing an unmatched
+begin-quote, except using 'changequote' to change the current quotes.
+
+   If the quotes should be changed from, say, '[' to '[[', temporary
+quote characters have to be defined.  To achieve this, two calls of
+'changequote' must be made, one for the temporary quotes and one for the
+new quotes.
+
+   Macros are recognized in preference to the begin-quote string, so if
+a prefix of START can be recognized as part of a potential macro name,
+the quoting mechanism is effectively disabled.  Unless you use
+'changeword' (*note Changeword::), this means that START should not
+begin with a letter, digit, or '_' (underscore).  However, even though
+quoted strings are not recognized, the quote characters can still be
+discerned in macro expansion and in trace output.

+     define(`echo', `$@')
+     =>
+     define(`hi', `HI')

+     changequote(`q', `Q')

+     =>qHIQ

+     =>
+     - hi EOF hi
+     => hi  HI

+     =>
+     changequote(`1', `2')
+     =>
+     hi1hi2
+     =>hi1hi2
+     hi 1hi2
+     =>HI hi
+
+   Quotes are recognized in preference to argument collection.  In
+particular, if START is a single '(', then argument collection is
+effectively disabled.  For portability with other implementations, it is
+a good idea to avoid '(', ',', and ')' as the first character in START.
+
+     define(`echo', `$#:$@:')
+     =>
+     define(`hi', `HI')
+     =>
+     changequote(`(',`)')
+     =>
+     echo(hi)
+     =>0::hi
+     changequote
+     =>
+     changequote(`((', `))')
+     =>
+     echo(hi)
+     =>1:HI:
+     echo((hi))
+     =>0::hi
+     changequote
+     =>
+     changequote(`,', `)')
+     =>
+     echo(hi,hi)bye)
+     =>1:HIhibye:
+
+   However, if you are not worried about portability, using '(' and ')'
+as quoting characters has an interesting property--you can use it to
+compute a quoted string containing the expansion of any quoted text, as
+long as the expansion results in both balanced quotes and balanced
+parentheses.  The trick is realizing 'expand' uses '$1' unquoted, to
+trigger its expansion using the normal quoting characters, but uses
+extra parentheses to group unquoted commas that occur in the expansion
+without consuming whitespace following those commas.  Then '_expand'
+uses 'changequote' to convert the extra parentheses back into quoting
+characters.  Note that it takes two more 'changequote' invocations to
+restore the original quotes.  Contrast the behavior on whitespace when
+using '$*', via 'quote', to attempt the same task.
+
+     changequote(`[', `]')dnl
+     define([a], [1, (b)])dnl
+     define([b], [2])dnl
+     define([quote], [[$*]])dnl
+     define([expand], [_$0(($1))])dnl
+     define([_expand],
+       [changequote([(], [)])$1changequote`'changequote(`[', `]')])dnl
+     expand([a, a, [a, a], [[a, a]]])
+     =>1, (2), 1, (2), a, a, [a, a]
+     quote(a, a, [a, a], [[a, a]])
+     =>1,(2),1,(2),a, a,[a, a]
+
+   If END is a prefix of START, the end-quote will be recognized in
+preference to a nested begin-quote.  In particular, changing the quotes
+to have the same string for START and END disables nesting of quotes.
+When quote nesting is disabled, it is impossible to double-quote strings
+across macro expansions, so using the same string is not done very
+often.
+
+     define(`hi', `HI')
+     =>
+     changequote(`""', `"')

+8.3 Changing the comment delimiters
+===================================
+
+The default comment delimiters can be changed with the builtin macro
+'changecom':
+
+ -- Builtin: changecom ([START]
+     This sets START as the new begin-comment delimiter and END as the
+     new end-comment delimiter.  If both arguments are missing, or START
+     is void, then comments are disabled.  Otherwise, if END is missing
+     or void, the default end-comment delimiter of newline is used.  The
+     comment delimiters can be of any length.
+
+     The expansion of 'changecom' is void.
+
+     define(`comment', `COMMENT')
+     =>
+     # A normal comment
+     =># A normal comment
+     changecom(`/*', `*/')
+     =>
+     # Not a comment anymore
+     =># Not a COMMENT anymore
+     But: /* this is a comment now */ while this is not a comment
+     =>But: /* this is a comment now */ while this is not a COMMENT
+
+   Note how comments are copied to the output, much as if they were
+quoted strings.  If you want the text inside a comment expanded, quote
+the begin-comment delimiter.
+
+   Calling 'changecom' without any arguments, or with START as the empty
+string, will effectively disable the commenting mechanism.  To restore
+the original comment start of '#', you must explicitly ask for it.  If
+START is not empty, then an empty END will use the default end-comment
+delimiter of newline, as otherwise, it would be impossible to end a
+comment.  However, this is not portable, as some other 'm4'
+implementations preserve the previous non-empty delimiters instead.
+
+     define(`comment', `COMMENT')
+     =>
+     changecom
+     =>
+     # Not a comment anymore
+     =># Not a COMMENT anymore
+     changecom(`#', `')
+     =>
+     # comment again
+     =># comment again
+
+   The comment strings can safely contain eight-bit characters.  If no
+single character is appropriate, START and END can be of any length.
+Other implementations cap the delimiter length to five characters, but
+GNU has no inherent limit.
+
+   Comments are recognized in preference to macros.  However, this is
+not compatible with other implementations, where macros and even quoting
+takes precedence over comments, so it may change in a future release.
+For portability, this means that START should not begin with a letter,
+digit, or '_' (underscore), and that neither the start-quote nor the
+start-comment string should be a prefix of the other.
+
+     define(`hi', `HI')
+     =>
+     define(`hi1hi2', `hello')
+     =>
+     changecom(`q', `Q')

+
+   Comments are recognized in preference to argument collection.  In
+particular, if START is a single '(', then argument collection is
+effectively disabled.  For portability with other implementations, it is
+a good idea to avoid '(', ',', and ')' as the first character in START.

+8.4 Changing the lexical structure of words
+===========================================
+
+     The macro 'changeword' and all associated functionality is
+     experimental.  It is only available if the '--enable-changeword'
+     option was given to 'configure', at GNU 'm4' installation time.
+     The functionality will go away in the future, to be replaced by
+     other new features that are more efficient at providing the same
+     capabilities.  _Do not rely on it_.  Please direct your comments
+     about it the same way you would do for bugs.
+
+   A file being processed by 'm4' is split into quoted strings, words
+(potential macro names) and simple tokens (any other single character).
+Initially a word is defined by the following regular expression:
+
+     [_a-zA-Z][_a-zA-Z0-9]*
+
+   Using 'changeword', you can change this regular expression:
+
+ -- Optional builtin: changeword (REGEX)
+     Changes the regular expression for recognizing macro names to be
+     REGEX.  If REGEX is empty, use '[_a-zA-Z][_a-zA-Z0-9]*'.  REGEX
+     must obey the constraint that every prefix of the desired final
+     pattern is also accepted by the regular expression.  If REGEX
+     contains grouping parentheses, the macro invoked is the portion
+     that matched the first group, rather than the entire matching
+     string.
+
+     The expansion of 'changeword' is void.  The macro 'changeword' is
+     recognized only with parameters.
+
+   Relaxing the lexical rules of 'm4' might be useful (for example) if
+you wanted to apply translations to a file of numbers:
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     changeword(`[_a-zA-Z0-9]+')
+     =>
+     define(`1', `0')1
+     =>0
+
+   Tightening the lexical rules is less useful, because it will
+generally make some of the builtins unavailable.  You could use it to
+prevent accidental call of builtins, for example:
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     define(`_indir', defn(`indir'))
+     =>
+     changeword(`_[_a-zA-Z0-9]*')
+     =>
+     esyscmd(`foo')
+     =>esyscmd(foo)
+     _indir(`esyscmd', `echo hi')
+     =>hi
+     =>
+
+   Because 'm4' constructs its words a character at a time, there is a
+restriction on the regular expressions that may be passed to
+'changeword'.  This is that if your regular expression accepts 'foo', it
+must also accept 'f' and 'fo'.
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     define(`foo
+     ', `bar
+     ')
+     =>
+     dnl This example wants to recognize changeword, dnl, and `foo\n'.
+     dnl First, we check that our regexp will match.
+     regexp(`changeword', `[cd][a-z]*\|foo[
+     ]')
+     =>0
+     regexp(`foo
+     ', `[cd][a-z]*\|foo[
+     ]')
+     =>0
+     regexp(`f', `[cd][a-z]*\|foo[
+     ]')
+     =>-1
+     foo
+     =>foo
+     changeword(`[cd][a-z]*\|foo[
+     ]')
+     =>
+     dnl Even though `foo\n' matches, we forgot to allow `f'.
+     foo
+     =>foo
+     changeword(`[cd][a-z]*\|fo*[
+     ]?')
+     =>
+     dnl Now we can call `foo\n'.
+     foo
+     =>bar
+
+   'changeword' has another function.  If the regular expression
+supplied contains any grouped subexpressions, then text outside the
+first of these is discarded before symbol lookup.  So:
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     ifdef(`__unix__', ,
+           `errprint(` skipping: syscmd does not have unix semantics
+     ')m4exit(`77')')dnl
+     changecom(`/*', `*/')dnl
+     define(`foo', `bar')dnl
+     changeword(`#\([_a-zA-Z0-9]*\)')
+     =>
+     #esyscmd(`echo foo \#foo')
+     =>foo bar
+     =>
+
+   'm4' now requires a '#' mark at the beginning of every macro
+invocation, so one can use 'm4' to preprocess plain text without losing
+various words like 'divert'.
+
+   In 'm4', macro substitution is based on text, while in TeX, it is
+based on tokens.  'changeword' can throw this difference into relief.
+For example, here is the same idea represented in TeX and 'm4'.  First,
+the TeX version:
+
+     \def\a{\message{Hello}}
+     \catcode`\@=0
+     \catcode`\\=12
+     @a
+     @bye
+     =>Hello
+
+Then, the 'm4' version:
+
+     ifdef(`changeword', `', `errprint(` skipping: no changeword support
+     ')m4exit(`77')')dnl
+     define(`a', `errprint(`Hello')')dnl
+     changeword(`@\([_a-zA-Z0-9]*\)')
+     =>
+     @a
+     =>errprint(Hello)
+
+   In the TeX example, the first line defines a macro 'a' to print the
+message 'Hello'.  The second line defines <@> to be usable instead of
+<\> as an escape character.  The third line defines <\> to be a normal
+printing character, not an escape.  The fourth line invokes the macro
+'a'.  So, when TeX is run on this file, it displays the message 'Hello'.
+
+   When the 'm4' example is passed through 'm4', it outputs
+'errprint(Hello)'.  The reason for this is that TeX does lexical
+analysis of macro definition when the macro is _defined_.  'm4' just
+stores the text, postponing the lexical analysis until the macro is
+_used_.
+
+   You should note that using 'changeword' will slow 'm4' down by a
+factor of about seven, once it is changed to something other than the
+default regular expression.  You can invoke 'changeword' with the empty
+string to restore the default word definition, and regain the parsing
+speed.

+
+8.5 Saving text until end of input
+==================================
+
+It is possible to 'save' some text until the end of the normal input has
+been seen.  Text can be saved, to be read again by 'm4' when the normal
+input has been exhausted.  This feature is normally used to initiate
+cleanup actions before normal exit, e.g., deleting temporary files.
+
+   To save input text, use the builtin 'm4wrap':
+
+ -- Builtin: m4wrap (STRING, ...)
+     Stores STRING in a safe place, to be reread when end of input is
+     reached.  As a GNU extension, additional arguments are concatenated
+     with a space to the STRING.
+
+     The expansion of 'm4wrap' is void.  The macro 'm4wrap' is
+     recognized only with parameters.
+
+     define(`cleanup', `This is the `cleanup' action.
+     ')
+     =>
+     m4wrap(`cleanup')
+     =>
+     This is the first and last normal input line.
+     =>This is the first and last normal input line.
+     ^D
+     =>This is the cleanup action.
+
+   The saved input is only reread when the end of normal input is seen,
+and not if 'm4exit' is used to exit 'm4'.
+
+   It is safe to call 'm4wrap' from saved text, but then the order in
+which the saved text is reread is undefined.  If 'm4wrap' is not used
+recursively, the saved pieces of text are reread in the opposite order
+in which they were saved (LIFO--last in, first out).  However, this
+behavior is likely to change in a future release, to match POSIX, so you
+should not depend on this order.
+
+   It is possible to emulate POSIX behavior even with older versions of
+GNU M4 by including the file 'm4-1.4.17/examples/wrapfifo.m4' from the
+distribution:
+
+     $ m4 -I examples
+     undivert(`wrapfifo.m4')dnl
+     =>dnl Redefine m4wrap to have FIFO semantics.
+     =>define(`_m4wrap_level', `0')dnl

+     =>       `builtin(`m4wrap', `define(`_m4wrap_level',
+     =>                                  incr(_m4wrap_level))dnl

+     m4wrap(`a`'m4wrap(`c
+     ', `d')')m4wrap(`b')
+     =>
+     ^D
+     =>abc
+
+   It is likewise possible to emulate LIFO behavior without resorting to
+the GNU M4 extension of 'builtin', by including the file
+'m4-1.4.17/examples/wraplifo.m4' from the distribution.  (Unfortunately,
+both examples shown here share some subtle bugs.  See if you can find
+and correct them; or *note Answers: Improved m4wrap.).

+     =>
+     f(`10')
+     =>
+     ^D
+     =>Answer: 10*9*8*7*6*5*4*3*2*1=3628800
+
+   Invocations of 'm4wrap' at the same recursion level are concatenated
+and rescanned as usual:
+
+     define(`aa', `AA

+     =>
+     m4wrap(`a')m4wrap(`a')

+file condition between two input files.

+
+9.1 Including named files
+=========================
+
+There are two builtin macros in 'm4' for including files:
+
+ -- Builtin: include (FILE)
+ -- Builtin: sinclude (FILE)
+     Both macros cause the file named FILE to be read by 'm4'.  When the
+     end of the file is reached, input is resumed from the previous
+     input file.
+
+     The expansion of 'include' and 'sinclude' is therefore the contents
+     of FILE.
+
+     If FILE does not exist, is a directory, or cannot otherwise be
+     read, the expansion is void, and 'include' will fail with an error
+     while 'sinclude' is silent.  The empty string counts as a file that
+     does not exist.
+
+     The macros 'include' and 'sinclude' are recognized only with
+     parameters.

+     include()

+     =>
+
+   The rest of this section assumes that 'm4' is invoked with the '-I'
+option (*note Invoking m4: Preprocessor features.) pointing to the
+'m4-1.4.17/examples' directory shipped as part of the GNU 'm4' package.
+The file 'm4-1.4.17/examples/incl.m4' in the distribution contains the
+lines:
+
+     $ cat examples/incl.m4
+     =>Include file start
+     =>foo
+     =>Include file end
+
+   Normally file inclusion is used to insert the contents of a file into
+the input stream.  The contents of the file will be read by 'm4' and
+macro calls in the file will be expanded:
+
+     $ m4 -I examples
+     define(`foo', `FOO')
+     =>
+     include(`incl.m4')
+     =>Include file start
+     =>FOO
+     =>Include file end
+     =>
+
+   The fact that 'include' and 'sinclude' expand to the contents of the
+file can be used to define macros that operate on entire files.  Here is
+an example, which defines 'bar' to expand to the contents of 'incl.m4':
+
+     $ m4 -I examples
+     define(`bar', include(`incl.m4'))
+     =>
+     This is `bar':  >>bar<<
+     =>This is bar:  >>Include file start
+     =>foo
+     =>Include file end
+     =><<
+
+   This use of 'include' is not trivial, though, as files can contain
+quotes, commas, and parentheses, which can interfere with the way the
+'m4' parser works.  GNU 'm4' seamlessly concatenates the file contents
+with the next character, even if the included file ended in the middle
+of a comment, string, or macro call.  These conditions are only treated
+as end of file errors if specified as input files on the command line.
+
+   In GNU 'm4', an alternative method of reading files is using
+'undivert' (*note Undivert::) on a named file.

+
+9.2 Searching for include files
+===============================
+
+GNU 'm4' allows included files to be found in other directories than the
+current working directory.
+
+   If the '--prepend-include' or '-B' command-line option was provided
+(*note Invoking m4: Preprocessor features.), those directories are
+searched first, in reverse order that those options were listed on the
+command line.  Then 'm4' looks in the current working directory.  Next
+comes the directories specified with the '--include' or '-I' option, in
+the order found on the command line.  Finally, if the 'M4PATH'
+environment variable is set, it is expected to contain a colon-separated
+list of directories, which will be searched in order.
+
+   If the automatic search for include-files causes trouble, the 'p'
+debug flag (*note Debug Levels::) can help isolate the problem.

+10 Diverting and undiverting output
+***********************************
+
+Diversions are a way of temporarily saving output.  The output of 'm4'
+can at any time be diverted to a temporary file, and be reinserted into
+the output stream, "undiverted", again at a later time.
+
+   Numbered diversions are counted from 0 upwards, diversion number 0
+being the normal output stream.  GNU 'm4' tries to keep diversions in
+memory.  However, there is a limit to the overall memory usable by all
+diversions taken together (512K, currently).  When this maximum is about
+to be exceeded, a temporary file is opened to receive the contents of
+the biggest diversion still in memory, freeing this memory for other
+diversions.  When creating the temporary file, 'm4' honors the value of
+the environment variable 'TMPDIR', and falls back to '/tmp'.  Thus, the
+amount of available disk space provides the only real limit on the
+number and aggregate size of diversions.
+
+   Diversions make it possible to generate output in a different order
+than the input was read.  It is possible to implement topological
+sorting dependencies.  For example, GNU Autoconf makes use of diversions
+under the hood to ensure that the expansion of a prerequisite macro
+appears in the output prior to the expansion of a dependent macro,
+regardless of which order the two macros were invoked in the user's
+input file.

+
+10.1 Diverting output
+=====================
+
+Output is diverted using 'divert':
+
+ -- Builtin: divert ([NUMBER = '0']
+     The current diversion is changed to NUMBER.  If NUMBER is left out
+     or empty, it is assumed to be zero.  If NUMBER cannot be parsed,
+     the diversion is unchanged.
+
+     The expansion of 'divert' is void.
+
+   When all the 'm4' input will have been processed, all existing
+diversions are automatically undiverted, in numerical order.
+
+     divert(`1')
+     This text is diverted.
+     divert
+     =>
+     This text is not diverted.
+     =>This text is not diverted.
+     ^D
+     =>
+     =>This text is diverted.
+
+   Several calls of 'divert' with the same argument do not overwrite the
+previous diverted text, but append to it.  Diversions are printed after
+any wrapped text is expanded.
+
+     define(`text', `TEXT')
+     =>
+     divert(`1')`diverted text.'
+     divert
+     =>
+     m4wrap(`Wrapped text precedes ')
+     =>
+     ^D
+     =>Wrapped TEXT precedes diverted text.
+
+   If output is diverted to a negative diversion, it is simply
+discarded.  This can be used to suppress unwanted output.  A common
+example of unwanted output is the trailing newlines after macro
+definitions.  Here is a common programming idiom in 'm4' for avoiding
+them.
+
+     divert(`-1')
+     define(`foo', `Macro `foo'.')
+     define(`bar', `Macro `bar'.')
+     divert
+     =>
+
+   Traditional implementations only supported ten diversions.  But as a
+GNU extension, diversion numbers can be as large as positive integers
+will allow, rather than treating a multi-digit diversion number as a
+request to discard text.
+
+     divert(eval(`1<<28'))world
+     divert(`2')hello
+     ^D
+     =>hello
+     =>world
+
+   Note that 'divert' is an English word, but also an active macro
+without arguments.  When processing plain text, the word might appear in
+normal text and be unintentionally swallowed as a macro invocation.  One
+way to avoid this is to use the '-P' option to rename all builtins
+(*note Invoking m4: Operation modes.).  Another is to write a wrapper
+that requires a parameter to be recognized.
+
+     We decided to divert the stream for irrigation.
+     =>We decided to  the stream for irrigation.
+     define(`divert', `ifelse(`$#', `0', ``$0'', `builtin(`$0', $@)')')

+     Ignored text.

+
+10.2 Undiverting output
+=======================
+
+Diverted text can be undiverted explicitly using the builtin 'undivert':
+
+ -- Builtin: undivert ([DIVERSIONS...]
+     Undiverts the numeric DIVERSIONS given by the arguments, in the
+     order given.  If no arguments are supplied, all diversions are
+     undiverted, in numerical order.
+
+     As a GNU extension, DIVERSIONS may contain non-numeric strings,
+     which are treated as the names of files to copy into the output
+     without expansion.  A warning is issued if a file could not be
+     opened.
+
+     The expansion of 'undivert' is void.
+
+     divert(`1')
+     This text is diverted.
+     divert
+     =>
+     This text is not diverted.
+     =>This text is not diverted.
+     undivert(`1')
+     =>
+     =>This text is diverted.
+     =>
+
+   Notice the last two blank lines.  One of them comes from the newline
+following 'undivert', the other from the newline that followed the
+'divert'!  A diversion often starts with a blank line like this.
+
+   When diverted text is undiverted, it is _not_ reread by 'm4', but
+rather copied directly to the current output, and it is therefore not an
+error to undivert into a diversion.  Undiverting the empty string is the
+same as specifying diversion 0; in either case nothing happens since the
+output has already been flushed.
+
+     divert(`1')diverted text
+     divert
+     =>
+     undivert()
+     =>
+     undivert(`0')
+     =>
+     undivert
+     =>diverted text
+     =>
+     divert(`1')more
+     divert(`2')undivert(`1')diverted text`'divert
+     =>
+     undivert(`1')
+     =>
+     undivert(`2')
+     =>more
+     =>diverted text
+
+   When a diversion has been undiverted, the diverted text is discarded,
+and it is not possible to bring back diverted text more than once.
+
+     divert(`1')
+     This text is diverted first.
+     divert(`0')undivert(`1')dnl
+     =>
+     =>This text is diverted first.
+     undivert(`1')
+     =>
+     divert(`1')
+     This text is also diverted but not appended.
+     divert(`0')undivert(`1')dnl
+     =>
+     =>This text is also diverted but not appended.
+
+   Attempts to undivert the current diversion are silently ignored.
+Thus, when the current diversion is not 0, the current diversion does
+not get rearranged among the other diversions.
+
+     divert(`1')one
+     divert(`2')two
+     divert(`3')three
+     divert(`2')undivert`'dnl
+     divert`'undivert`'dnl
+     =>two
+     =>one
+     =>three
+
+   GNU 'm4' allows named files to be undiverted.  Given a non-numeric
+argument, the contents of the file named will be copied, uninterpreted,
+to the current output.  This complements the builtin 'include' (*note
+Include::).  To illustrate the difference, assume the file 'foo'
+contains:
+
+     $ cat foo
+     bar
+
+then
+
+     define(`bar', `BAR')
+     =>
+     undivert(`foo')
+     =>bar
+     =>
+     include(`foo')
+     =>BAR
+     =>
+
+   If the file is not found (or cannot be read), an error message is
+issued, and the expansion is void.  It is possible to intermix files and
+diversion numbers.
+
+     divert(`1')diversion one
+     divert(`2')undivert(`foo')dnl
+     divert(`3')diversion three

+10.3 Diversion numbers
+======================
+
+The current diversion is tracked by the builtin 'divnum':
+
+ -- Builtin: divnum
+     Expands to the number of the current diversion.
+
+     Initial divnum
+     =>Initial 0
+     divert(`1')
+     Diversion one: divnum
+     divert(`2')
+     Diversion two: divnum
+     ^D
+     =>
+     =>Diversion one: 1
+     =>
+     =>Diversion two: 2
+
+
+File: m4.info,  Node: Cleardivert,  Prev: Divnum,  Up: Diversions
+
+10.4 Discarding diverted text
+=============================
+
+Often it is not known, when output is diverted, whether the diverted
+text is actually needed.  Since all non-empty diversion are brought back
+on the main output stream when the end of input is seen, a method of
+discarding a diversion is needed.  If all diversions should be
+discarded, the easiest is to end the input to 'm4' with 'divert(`-1')'
+followed by an explicit 'undivert':
+
+     divert(`1')
+     Diversion one: divnum
+     divert(`2')
+     Diversion two: divnum
+     divert(`-1')
+     undivert
+     ^D
+
+No output is produced at all.
+
+   Clearing selected diversions can be done with the following macro:
+
+ -- Composite: cleardivert ([DIVERSIONS...]
+     Discard the contents of each of the listed numeric DIVERSIONS.
+
+     define(`cleardivert',
+     `pushdef(`_n', divnum)divert(`-1')undivert($@)divert(_n)popdef(`_n')')
+     =>
+
+   It is called just like 'undivert', but the effect is to clear the
+diversions, given by the arguments.  (This macro has a nasty bug!  You
+should try to see if you can find it and correct it; or *note Answers:
+Improved cleardivert.).

+     Expands to the index of the first occurrence of SUBSTRING in

+
+11.3 Searching for regular expressions
+======================================
+
+Searching for regular expressions is done with the builtin 'regexp':
+
+ -- Builtin: regexp (STRING, REGEXP, [REPLACEMENT]
+     Searches for REGEXP in STRING.  The syntax for regular expressions
+     is the same as in GNU Emacs, which is similar to BRE, Basic Regular
+     Expressions in POSIX. *Note Syntax of Regular Expressions:
+     (emacs)Regexps.  Support for ERE, Extended Regular Expressions is
+     not available, but will be added in GNU M4 2.0.
+
+     If REPLACEMENT is omitted, 'regexp' expands to the index of the
+     first match of REGEXP in STRING.  If REGEXP does not match anywhere
+     in STRING, it expands to -1.
+
+     If REPLACEMENT is supplied, and there was a match, 'regexp' changes
+     the expansion to this argument, with '\N' substituted by the text
+     matched by the Nth parenthesized sub-expression of REGEXP, up to
+     nine sub-expressions.  The escape '\&' is replaced by the text of
+     the entire regular expression matched.  For all other characters,
+     '\' treats the next character literally.  A warning is issued if
+     there were fewer sub-expressions than the '\N' requested, or if
+     there is a trailing '\'.  If there was no match, 'regexp' expands
+     to the empty string.
+
+     The macro 'regexp' is recognized only with parameters.
+
+     regexp(`GNUs not Unix', `\<[a-z]\w+')
+     =>5
+     regexp(`GNUs not Unix', `\<Q\w*')

+11.4 Extracting substrings
+==========================
+
+Substrings are extracted with 'substr':
+
+ -- Builtin: substr (STRING, FROM, [LENGTH]
+     Expands to the substring of STRING, which starts at index FROM, and
+     extends for LENGTH characters, or to the end of STRING, if LENGTH
+     is omitted.  The starting index of a string is always 0.  The
+     expansion is empty if there is an error parsing FROM or LENGTH, if
+     FROM is beyond the end of STRING, or if LENGTH is negative.
+
+     The macro 'substr' is recognized only with parameters.

+File: m4.info,  Node: Translit,  Next: Patsubst,  Prev: Substr,  Up: Text handling
+
+11.5 Translating characters
+===========================
+
+Character translation is done with 'translit':
+
+ -- Builtin: translit (STRING, CHARS, [REPLACEMENT]
+     Expands to STRING, with each character that occurs in CHARS
+     translated into the character from REPLACEMENT with the same index.
+
+     If REPLACEMENT is shorter than CHARS, the excess characters of
+     CHARS are deleted from the expansion; if CHARS is shorter, the
+     excess characters in REPLACEMENT are silently ignored.  If
+     REPLACEMENT is omitted, all characters in STRING that are present
+     in CHARS are deleted from the expansion.  If a character appears
+     more than once in CHARS, only the first instance is used in making
+     the translation.  Only a single translation pass is made, even if
+     characters in REPLACEMENT also appear in CHARS.
+
+     As a GNU extension, both CHARS and REPLACEMENT can contain
+     character-ranges, e.g., 'a-z' (meaning all lowercase letters) or
+     '0-9' (meaning all digits).  To include a dash '-' in CHARS or
+     REPLACEMENT, place it first or last in the entire string, or as the
+     last character of a range.  Back-to-back ranges can share a common
+     endpoint.  It is not an error for the last character in the range
+     to be 'larger' than the first.  In that case, the range runs
+     backwards, i.e., '9-0' means the string '9876543210'.  The
+     expansion of a range is dependent on the underlying encoding of
+     characters, so using ranges is not always portable between
+     machines.
+
+     The macro 'translit' is recognized only with parameters.
+
+     translit(`GNUs not Unix', `A-Z')
+     =>s not nix
+     translit(`GNUs not Unix', `a-z', `A-Z')
+     =>GNUS NOT UNIX

+     =>tmfs not fnix
+     translit(`+,-12345', `+--1-5', `<;>a-c-a')
+     =><;>abcba
+     translit(`abcdef', `aabdef', `bcged')
+     =>bgced
+
+   In the ASCII encoding, the first example deletes all uppercase
+letters, the second converts lowercase to uppercase, and the third
+'mirrors' all uppercase letters, while converting them to lowercase.
+The two first cases are by far the most common, even though they are not
+portable to EBCDIC or other encodings.  The fourth example shows a range
+ending in '-', as well as back-to-back ranges.  The final example shows
+that 'a' is mapped to 'b', not 'c'; the resulting 'b' is not further
+remapped to 'g'; the 'd' and 'e' are swapped, and the 'f' is discarded.
+
+   Omitting CHARS evokes a warning, but still produces output.

+
+11.6 Substituting text by regular expression
+============================================
+
+Global substitution in a string is done by 'patsubst':
+
+ -- Builtin: patsubst (STRING, REGEXP, [REPLACEMENT]
+     Searches STRING for matches of REGEXP, and substitutes REPLACEMENT
+     for each match.  The syntax for regular expressions is the same as
+     in GNU Emacs (*note Regexp::).
+
+     The parts of STRING that are not covered by any match of REGEXP are
+     copied to the expansion.  Whenever a match is found, the search
+     proceeds from the end of the match, so a character from STRING will
+     never be substituted twice.  If REGEXP matches a string of zero
+     length, the start position for the search is incremented, to avoid
+     infinite loops.
+
+     When a replacement is to be made, REPLACEMENT is inserted into the
+     expansion, with '\N' substituted by the text matched by the Nth
+     parenthesized sub-expression of PATSUBST, for up to nine
+     sub-expressions.  The escape '\&' is replaced by the text of the
+     entire regular expression matched.  For all other characters, '\'
+     treats the next character literally.  A warning is issued if there
+     were fewer sub-expressions than the '\N' requested, or if there is
+     a trailing '\'.
+
+     The REPLACEMENT argument can be omitted, in which case the text
+     matched by REGEXP is deleted.
+
+     The macro 'patsubst' is recognized only with parameters.
+
+     patsubst(`GNUs not Unix', `^', `OBS: ')
+     =>OBS: GNUs not Unix
+     patsubst(`GNUs not Unix', `\<', `OBS: ')
+     =>OBS: GNUs OBS: not OBS: Unix
+     patsubst(`GNUs not Unix', `\w*', `(\&)')
+     =>(GNUs)() (not)() (Unix)()
+     patsubst(`GNUs not Unix', `\w+', `(\&)')
+     =>(GNUs) (not) (Unix)
+     patsubst(`GNUs not Unix', `[A-Z][a-z]+')
+     =>GN not 
+     patsubst(`GNUs not Unix', `not', `NOT\')
+     error->m4:stdin:6: Warning: trailing \ ignored in replacement
+     =>GNUs NOT Unix
+
+   Here is a slightly more realistic example, which capitalizes
+individual words or whole sentences, by substituting calls of the macros
+'upcase' and 'downcase' into the strings.
+
+ -- Composite: upcase (TEXT)
+ -- Composite: downcase (TEXT)
+ -- Composite: capitalize (TEXT)
+     Expand to TEXT, but with capitalization changed: 'upcase' changes
+     all letters to upper case, 'downcase' changes all letters to lower
+     case, and 'capitalize' changes the first character of each word to
+     upper case and the remaining characters to lower case.
+
+   First, an example of their usage, using implementations distributed
+in 'm4-1.4.17/examples/capitalize.m4'.
+
+     $ m4 -I examples
+     include(`capitalize.m4')
+     =>
+     upcase(`GNUs not Unix')
+     =>GNUS NOT UNIX
+     downcase(`GNUs not Unix')
+     =>gnus not unix
+     capitalize(`GNUs not Unix')
+     =>Gnus Not Unix
+
+   Now for the implementation.  There is a helper macro '_capitalize'
+which puts only its first word in mixed case.  Then 'capitalize' merely
+parses out the words, and replaces them with an invocation of
+'_capitalize'.  (As presented here, the 'capitalize' macro has some
+subtle flaws.  You should try to see if you can find and correct them;
+or *note Answers: Improved capitalize.).
+
+     $ m4 -I examples
+     undivert(`capitalize.m4')dnl
+     =>divert(`-1')
+     =># upcase(text)
+     =># downcase(text)
+     =># capitalize(text)
+     =>#   change case of text, simple version
+     =>define(`upcase', `translit(`$*', `a-z', `A-Z')')
+     =>define(`downcase', `translit(`$*', `A-Z', `a-z')')
+     =>define(`_capitalize',
+     =>       `regexp(`$1', `^\(\w\)\(\w*\)',
+     =>               `upcase(`\1')`'downcase(`\2')')')
+     =>define(`capitalize', `patsubst(`$1', `\w+', `_$0(`\&')')')
+     =>divert`'dnl
+
+   While 'regexp' replaces the whole input with the replacement as soon
+as there is a match, 'patsubst' replaces each _occurrence_ of a match
+and preserves non-matching pieces:
+
+     define(`patreg',
+     `patsubst($@)
+     regexp($@)')dnl
+     patreg(`bar foo baz Foo', `foo\|Foo', `FOO')
+     =>bar FOO baz FOO
+     =>FOO
+     patreg(`aba abb 121', `\(.\)\(.\)\1', `\2\1\2')
+     =>bab abb 212
+     =>bab
+
+   Omitting REGEXP evokes a warning, but still produces output; contrast
+this with an empty REGEXP argument.
+
+     patsubst(`abc')
+     error->m4:stdin:1: Warning: too few arguments to builtin `patsubst'

+11.7 Formatting strings (printf-like)
+=====================================
+
+Formatted output can be made with 'format':
+
+ -- Builtin: format (FORMAT-STRING, ...)
+     Works much like the C function 'printf'.  The first argument
+     FORMAT-STRING can contain '%' specifications which are satisfied by
+     additional arguments, and the expansion of 'format' is the
+     formatted string.
+
+     The macro 'format' is recognized only with parameters.
+
+   Its use is best described by a few examples:
+
+     define(`foo', `The brown fox jumped over the lazy dog')
+     =>
+     format(`The string "%s" uses %d characters', foo, len(foo))
+     =>The string "The brown fox jumped over the lazy dog" uses 38 characters
+     format(`%*.*d', `-1', `-1', `1')
+     =>1
+     format(`%.0f', `56789.9876')
+     =>56790
+     len(format(`%-*X', `5000', `1'))
+     =>5000
+     ifelse(format(`%010F', `infinity'), `       INF', `success',
+            format(`%010F', `infinity'), `  INFINITY', `success',
+            format(`%010F', `infinity'))
+     =>success
+     ifelse(format(`%.1A', `1.999'), `0X1.0P+1', `success',
+            format(`%.1A', `1.999'), `0X2.0P+0', `success',
+            format(`%.1A', `1.999'))
+     =>success
+     format(`%g', `0xa.P+1')
+     =>20
+
+   Using the 'forloop' macro defined earlier (*note Forloop::), this
+example shows how 'format' can be used to produce tabular output.
+
+     $ m4 -I examples
+     include(`forloop.m4')
+     =>
+     forloop(`i', `1', `10', `format(`%6d squared is %10d
+     ', i, eval(i**2))')
+     =>     1 squared is          1
+     =>     2 squared is          4
+     =>     3 squared is          9
+     =>     4 squared is         16
+     =>     5 squared is         25
+     =>     6 squared is         36
+     =>     7 squared is         49
+     =>     8 squared is         64
+     =>     9 squared is         81
+     =>    10 squared is        100
+     =>
+
+   The builtin 'format' is modeled after the ANSI C 'printf' function,
+and supports these '%' specifiers: 'c', 's', 'd', 'o', 'x', 'X', 'u',
+'a', 'A', 'e', 'E', 'f', 'F', 'g', 'G', and '%'; it supports field
+widths and precisions, and the flags '+', '-', ' ', '0', '#', and '''.
+For integer specifiers, the width modifiers 'hh', 'h', and 'l' are
+recognized, and for floating point specifiers, the width modifier 'l' is
+recognized.  Items not yet supported include positional arguments, the
+'n', 'p', 'S', and 'C' specifiers, the 'z', 't', 'j', 'L' and 'll'
+modifiers, and any platform extensions available in the native 'printf'.
+For more details on the functioning of 'printf', see the C Library
+Manual, or the POSIX specification (for example, '%a' is supported even
+on platforms that haven't yet implemented C99 hexadecimal floating point
+output natively).
+
+   Unrecognized specifiers result in a warning.  It is anticipated that
+a future release of GNU 'm4' will support more specifiers, and give
+better warnings when various problems such as overflow are encountered.
+Likewise, escape sequences are not yet recognized.

+12 Macros for doing arithmetic
+******************************
+
+Integer arithmetic is included in 'm4', with a C-like syntax.  As
+convenient shorthands, there are builtins for simple increment and
+decrement operations.
+
+* Menu:
+
+* Incr::                        Decrement and increment operators

+
+File: m4.info,  Node: Incr,  Next: Eval,  Up: Arithmetic
+
+12.1 Decrement and increment operators
+======================================
+
+Increment and decrement of integers are supported using the builtins
+'incr' and 'decr':
+
+ -- Builtin: incr (NUMBER)
+ -- Builtin: decr (NUMBER)
+     Expand to the numerical value of NUMBER, incremented or
+     decremented, respectively, by one.  Except for the empty string,

+
+12.2 Evaluating integer expressions
+===================================
+
+Integer expressions are evaluated with 'eval':
+
+ -- Builtin: eval (EXPRESSION, [RADIX = '10']
+     Expands to the value of EXPRESSION.  The expansion is empty if a
+     problem is encountered while parsing the arguments.  If specified,
+     RADIX and WIDTH control the format of the output.
+
+     Calculations are done with 32-bit signed numbers.  Overflow
+     silently results in wraparound.  A warning is issued if division by
+     zero is attempted, or if EXPRESSION could not be parsed.
+
+     Expressions can contain the following operators, listed in order of
+     decreasing precedence.
+
+     '()'
+          Parentheses
+     '+ - ~ !'
+          Unary plus and minus, and bitwise and logical negation
+     '**'
+          Exponentiation
+     '* / %'
+          Multiplication, division, and modulo
+     '+ -'
+          Addition and subtraction
+     '<< >>'
+          Shift left or right
+     '> >= < <='
+          Relational operators
+     '== !='
+          Equality operators
+     '&'
+          Bitwise and
+     '^'
+          Bitwise exclusive-or
+     '|'
+          Bitwise or
+     '&&'
+          Logical and
+     '||'
+          Logical or
+
+     The macro 'eval' is recognized only with parameters.
+
+   All binary operators, except exponentiation, are left associative.  C
+operators that perform variable assignment, such as '+=' or '--', are
+not implemented, since 'eval' only operates on constants, not variables.
+Attempting to use them results in an error.  However, since traditional
+implementations treated '=' as an undocumented alias for '==' as opposed
+to an assignment operator, this usage is supported as a special case.
+Be aware that a future version of GNU M4 may support assignment
+semantics as an extension when POSIX mode is not requested, and that
+using '=' to check equality is not portable.
+
+     eval(`2 = 2')
+     error->m4:stdin:1: Warning: recommend ==, not =, for equality operator
+     =>1
+     eval(`++0')
+     error->m4:stdin:2: invalid operator in eval: ++0
+     =>
+     eval(`0 |= 1')
+     error->m4:stdin:3: invalid operator in eval: 0 |= 1
+     =>
+
+   Note that some older 'm4' implementations use '^' as an alternate
+operator for the exponentiation, although POSIX requires the C behavior
+of bitwise exclusive-or.  The precedence of the negation operators, '~'
+and '!', was traditionally lower than equality.  The unary operators
+could not be used reliably more than once on the same term without
+intervening parentheses.  The traditional precedence of the equality
+operators '==' and '!=' was identical instead of lower than the
+relational operators such as '<', even through GNU M4 1.4.8.  Starting
+with version 1.4.9, GNU M4 correctly follows POSIX precedence rules.  M4
+scripts designed to be portable between releases must be aware that
+parentheses may be required to enforce C precedence rules.  Likewise,
+division by zero, even in the unused branch of a short-circuiting
+operator, is not always well-defined in other implementations.
+
+   Following are some examples where the current version of M4 follows C
+precedence rules, but where older versions and some other
+implementations of 'm4' require explicit parentheses to get the correct
+result:
+
+     eval(`1 == 2 > 0')
+     =>1
+     eval(`(1 == 2) > 0')
+     =>0
+     eval(`! 0 * 2')
+     =>2
+     eval(`! (0 * 2)')
+     =>1
+     eval(`1 | 1 ^ 1')
+     =>1
+     eval(`(1 | 1) ^ 1')
+     =>0
+     eval(`+ + - ~ ! ~ 0')
+     =>1
+     eval(`2 || 1 / 0')
+     =>1
+     eval(`0 || 1 / 0')
+     error->m4:stdin:9: divide by zero in eval: 0 || 1 / 0
+     =>
+     eval(`0 && 1 % 0')
+     =>0
+     eval(`2 && 1 % 0')
+     error->m4:stdin:11: modulo by zero in eval: 2 && 1 % 0
+     =>
+
+   As a GNU extension, the operator '**' performs integral
+exponentiation.  The operator is right-associative, and if evaluated,
+the exponent must be non-negative, and at least one of the arguments
+must be non-zero, or a warning is issued.
+
+     eval(`2 ** 3 ** 2')
+     =>512
+     eval(`(2 ** 3) ** 2')
+     =>64
+     eval(`0 ** 1')
+     =>0
+     eval(`2 ** 0')
+     =>1
+     eval(`0 ** 0')
+     =>
+     error->m4:stdin:5: divide by zero in eval: 0 ** 0
+     eval(`4 ** -2')
+     error->m4:stdin:6: negative exponent in eval: 4 ** -2
+     =>
+
+   Within EXPRESSION, (but not RADIX or WIDTH), numbers without a
+special prefix are decimal.  A simple '0' prefix introduces an octal
+number.  '0x' introduces a hexadecimal number.  As GNU extensions, '0b'
+introduces a binary number.  '0r' introduces a number expressed in any
+radix between 1 and 36: the prefix should be immediately followed by the
+decimal expression of the radix, a colon, then the digits making the
+number.  For radix 1, leading zeros are ignored, and all remaining
+digits must be '1'; for all other radices, the digits are '0', '1', '2',
+....  Beyond '9', the digits are 'a', 'b' ... up to 'z'.  Lower and
+upper case letters can be used interchangeably in numbers prefixes and
+as number digits.
+
+   Parentheses may be used to group subexpressions whenever needed.  For
+the relational operators, a true relation returns '1', and a false
+relation return '0'.
+
+   Here are a few examples of use of 'eval'.
+
+     eval(`-3 * 5')
+     =>-15
+     eval(`-99 / 10')
+     =>-9
+     eval(`-99 % 10')
+     =>-9
+     eval(`99 % -10')
+     =>9
+     eval(index(`Hello world', `llo') >= 0)
+     =>1
+     eval(`0r1:0111 + 0b100 + 0r3:12')
+     =>12
+     define(`square', `eval(`($1) ** 2')')
+     =>
+     square(`9')
+     =>81
+     square(square(`5')` + 1')
+     =>676

+     =>
+     eval(`foo / 6')
+     error->m4:stdin:11: bad expression in eval: foo / 6
+     =>
+     eval(foo / 6)
+     =>111
+
+   As the last two lines show, 'eval' does not handle macro names, even
+if they expand to a valid expression (or part of a valid expression).
+Therefore all macros must be expanded before they are passed to 'eval'.
+
+   Some calculations are not portable to other implementations, since
+they have undefined semantics in C, but GNU 'm4' has well-defined
+behavior on overflow.  When shifting, an out-of-range shift amount is
+implicitly brought into the range of 32-bit signed integers using an
+implicit bit-wise and with 0x1f).
+
+     define(`max_int', eval(`0x7fffffff'))
+     =>
+     define(`min_int', incr(max_int))
+     =>
+     eval(min_int` < 0')
+     =>1
+     eval(max_int` > 0')

+     =>0
+     eval(`-4 >> 1')
+     =>-2
+     eval(`-4 >> 33')
+     =>-2
+
+   If RADIX is specified, it specifies the radix to be used in the
+expansion.  The default radix is 10; this is also the case if RADIX is
+the empty string.  A warning results if the radix is outside the range
+of 1 through 36, inclusive.  The result of 'eval' is always taken to be
+signed.  No radix prefix is output, and for radices greater than 10, the
+digits are lower case.  The WIDTH argument specifies the minimum output
+width, excluding any negative sign.  The result is zero-padded to extend
+the expansion to the requested width.  A warning results if the width is
+negative.  If RADIX or WIDTH is out of bounds, the expansion of 'eval'
+is empty.

+commands from within 'm4'.
+
+   Note that the definition of a valid shell command is system
+dependent.  On UNIX systems, this is the typical '/bin/sh'.  But on
+other systems, such as native Windows, the shell has a different syntax
+of commands that it understands.  Some examples in this chapter assume
+'/bin/sh', and also demonstrate how to quit early with a known exit

+
+13.1 Determining the platform
+=============================
+
+Sometimes it is desirable for an input file to know which platform 'm4'
+is running on.  GNU 'm4' provides several macros that are predefined to
+expand to the empty string; checking for their existence will confirm
+platform details.
+
+ -- Optional builtin: __gnu__
+ -- Optional builtin: __os2__
+ -- Optional builtin: os2
+ -- Optional builtin: __unix__
+ -- Optional builtin: unix
+ -- Optional builtin: __windows__
+ -- Optional builtin: windows
+     Each of these macros is conditionally defined as needed to describe
+     the environment of 'm4'.  If defined, each macro expands to the
+     empty string.  For now, these macros silently ignore all arguments,
+     but in a future release of M4, they might warn if arguments are
+     present.
+
+   When GNU extensions are in effect (that is, when you did not use the
+'-G' option, *note Invoking m4: Limits control.), GNU 'm4' will define
+the macro '__gnu__' to expand to the empty string.
+
+     $ m4
+     __gnu__
+     =>
+     __gnu__(`ignored')
+     =>
+     Extensions are ifdef(`__gnu__', `active', `inactive')

+     __gnu__(`ignored')
+     =>__gnu__(ignored)
+     Extensions are ifdef(`__gnu__', `active', `inactive')
+     =>Extensions are inactive
+
+   On UNIX systems, GNU 'm4' will define '__unix__' by default, or
+'unix' when the '-G' option is specified.
+
+   On native Windows systems, GNU 'm4' will define '__windows__' by
+default, or 'windows' when the '-G' option is specified.
+
+   On OS/2 systems, GNU 'm4' will define '__os2__' by default, or 'os2'
+when the '-G' option is specified.
+
+   If GNU 'm4' does not provide a platform macro for your system, please
+report that as a bug.

+13.2 Executing simple commands
+==============================
+
+Any shell command can be executed, using 'syscmd':
+
+ -- Builtin: syscmd (SHELL-COMMAND)
+     Executes SHELL-COMMAND as a shell command.
+
+     The expansion of 'syscmd' is void, _not_ the output from
+     SHELL-COMMAND!  Output or error messages from SHELL-COMMAND are not
+     read by 'm4'.  *Note Esyscmd::, if you need to process the command
+     output.
+
+     Prior to executing the command, 'm4' flushes its buffers.  The
+     default standard input, output and error of SHELL-COMMAND are the
+     same as those of 'm4'.
+
+     By default, the SHELL-COMMAND will be used as the argument to the
+     '-c' option of the '/bin/sh' shell (or the version of 'sh'
+     specified by 'command -p getconf PATH', if your system supports
+     that).  If you prefer a different shell, the 'configure' script can
+     be given the option '--with-syscmd-shell=LOCATION' to set the
+     location of an alternative shell at GNU 'm4' installation; the
+     alternative shell must still support '-c'.
+
+     The macro 'syscmd' is recognized only with parameters.
+
+     define(`foo', `FOO')
+     =>
+     syscmd(`echo foo')
+     =>foo
+     =>
+
+   Note how the expansion of 'syscmd' keeps the trailing newline of the
+command, as well as using the newline that appeared after the macro.
+
+   The following is an example of SHELL-COMMAND using the same standard
+input as 'm4':
+
+     $ echo "m4wrap(\`syscmd(\`cat')')" | m4
+     =>
+
+   It tells 'm4' to read all of its input before executing the wrapped
+text, then hand a valid (albeit emptied) pipe as standard input for the
+'cat' subcommand.  Therefore, you should be careful when using standard
+input (either by specifying no files, or by passing '-' as a file name
+on the command line, *note Invoking m4: Command line files.), and also
+invoking subcommands via 'syscmd' or 'esyscmd' that consume data from
+standard input.  When standard input is a seekable file, the subprocess
+will pick up with the next character not yet processed by 'm4'; when it
+is a pipe or other non-seekable file, there is no guarantee how much
+data will already be buffered by 'm4' and thus unavailable to the child.

+
+13.3 Reading the output of commands
+===================================
+
+If you want 'm4' to read the output of a shell command, use 'esyscmd':
+
+ -- Builtin: esyscmd (SHELL-COMMAND)
+     Expands to the standard output of the shell command SHELL-COMMAND.
+
+     Prior to executing the command, 'm4' flushes its buffers.  The
+     default standard input and standard error of SHELL-COMMAND are the
+     same as those of 'm4'.  The error output of SHELL-COMMAND is not a
+     part of the expansion: it will appear along with the error output
+     of 'm4'.
+
+     By default, the SHELL-COMMAND will be used as the argument to the
+     '-c' option of the '/bin/sh' shell (or the version of 'sh'
+     specified by 'command -p getconf PATH', if your system supports
+     that).  If you prefer a different shell, the 'configure' script can
+     be given the option '--with-syscmd-shell=LOCATION' to set the
+     location of an alternative shell at GNU 'm4' installation; the
+     alternative shell must still support '-c'.
+
+     The macro 'esyscmd' is recognized only with parameters.
+
+     define(`foo', `FOO')
+     =>
+     esyscmd(`echo foo')
+     =>FOO
+     =>
+
+   Note how the expansion of 'esyscmd' keeps the trailing newline of the
+command, as well as using the newline that appeared after the macro.
+
+   Just as with 'syscmd', care must be exercised when sharing standard
+input between 'm4' and the child process of 'esyscmd'.

+
+13.4 Exit status
+================
+
+To see whether a shell command succeeded, use 'sysval':
+
+ -- Builtin: sysval
+     Expands to the exit status of the last shell command run with
+     'syscmd' or 'esyscmd'.  Expands to 0 if no command has been run
+     yet.
+
+     sysval
+     =>0
+     syscmd(`false')
+     =>
+     ifelse(sysval, `0', `zero', `non-zero')
+     =>non-zero
+     syscmd(`exit 2')
+     =>
+     sysval
+     =>2
+     syscmd(`true')
+     =>
+     sysval
+     =>0
+     esyscmd(`false')
+     =>
+     ifelse(sysval, `0', `zero', `non-zero')
+     =>non-zero
+     esyscmd(`echo dnl && exit 127')
+     =>
+     sysval
+     =>127
+     esyscmd(`true')
+     =>
+     sysval
+     =>0
+
+   'sysval' results in 127 if there was a problem executing the command,
+for example, if the system-imposed argument length is exceeded, or if
+there were not enough resources to fork.  It is not possible to
+distinguish between failed execution and successful execution that had
+an exit status of 127, unless there was output from the child process.
+
+   On UNIX platforms, where it is possible to detect when command
+execution is terminated by a signal, rather than a normal exit, the
+result is the signal number shifted left by eight bits.
+
+     dnl This test assumes kill is a shell builtin, and that signals are
+     dnl recognizable.
+     ifdef(`__unix__', ,
+           `errprint(` skipping: syscmd does not have unix semantics

+
+13.5 Making temporary files
+===========================
+
+Commands specified to 'syscmd' or 'esyscmd' might need a temporary file,
+for output or for some other purpose.  There is a builtin macro,
+'mkstemp', for making a temporary file:
+
+ -- Builtin: mkstemp (TEMPLATE)
+ -- Builtin: maketemp (TEMPLATE)
+     Expands to the quoted name of a new, empty file, made from the
+     string TEMPLATE, which should end with the string 'XXXXXX'.  The
+     six 'X' characters are then replaced with random characters
+     matching the regular expression '[a-zA-Z0-9._-]', in order to make
+     the file name unique.  If fewer than six 'X' characters are found
+     at the end of 'template', the result will be longer than the
+     template.  The created file will have access permissions as if by
+     'chmod =rw,go=', meaning that the current umask of the 'm4' process
+     is taken into account, and at most only the current user can read
+     and write the file.
+
+     The traditional behavior, standardized by POSIX, is that 'maketemp'
+     merely replaces the trailing 'X' with the process id, without
+     creating a file or quoting the expansion, and without ensuring that
+     the resulting string is a unique file name.  In part, this means
+     that using the same TEMPLATE twice in the same input file will
+     result in the same expansion.  This behavior is a security hole, as
+     it is very easy for another process to guess the name that will be
+     generated, and thus interfere with a subsequent use of 'syscmd'
+     trying to manipulate that file name.  Hence, POSIX has recommended
+     that all new implementations of 'm4' provide the secure 'mkstemp'
+     builtin, and that users of 'm4' check for its existence.
+
+     The expansion is void and an error issued if a temporary file could
+     not be created.
+
+     The macros 'mkstemp' and 'maketemp' are recognized only with
+     parameters.
+
+   If you try this next example, you will most likely get different
+output for the two file names, since the replacement characters are
+randomly chosen:
+
+     $ m4
+     define(`tmp', `oops')
+     =>
+     maketemp(`/tmp/fooXXXXXX')
+     =>/tmp/fooa07346
+     ifdef(`mkstemp', `define(`maketemp', defn(`mkstemp'))',
+           `define(`mkstemp', defn(`maketemp'))dnl
+     errprint(`warning: potentially insecure maketemp implementation
+     ')')
+     =>
+     mkstemp(`doc')
+     =>docQv83Uw
+
+   Unless you use the '--traditional' command line option (or '-G',
+*note Invoking m4: Limits control.), the GNU version of 'maketemp' is
+secure.  This means that using the same template to multiple calls will
+generate multiple files.  However, we recommend that you use the new
+'mkstemp' macro, introduced in GNU M4 1.4.8, which is secure even in
+traditional mode.  Also, as of M4 1.4.11, the secure implementation
+quotes the resulting file name, so that you are guaranteed to know what
+file was created even if the random file name happens to match an
+existing macro.  Notice that this example is careful to use 'defn' to
+avoid unintended expansion of 'foo'.
+
+     $ m4
+     define(`foo', `errprint(`oops')')
+     =>
+     syscmd(`rm -f foo-??????')sysval
+     =>0
+     define(`file1', maketemp(`foo-XXXXXX'))dnl
+     ifelse(esyscmd(`echo \` foo-?????? \''), ` foo-?????? ',
+            `no file', `created')
+     =>created
+     define(`file2', maketemp(`foo-XX'))dnl
+     define(`file3', mkstemp(`foo-XXXXXX'))dnl
+     ifelse(len(defn(`file1')), len(defn(`file2')),
+            `same length', `different')
+     =>same length

+File: m4.info,  Node: Errprint,  Next: Location,  Up: Miscellaneous
+
+14.1 Printing error messages
+============================
+
+You can print error messages using 'errprint':
+
+ -- Builtin: errprint (MESSAGE, ...)
+     Prints MESSAGE and the rest of the arguments to standard error,
+     separated by spaces.  Standard error is used, regardless of the
+     '--debugfile' option (*note Invoking m4: Debugging options.).
+
+     The expansion of 'errprint' is void.  The macro 'errprint' is
+     recognized only with parameters.
+
+     errprint(`Invalid arguments to forloop
+     ')
+     error->Invalid arguments to forloop
+     =>
+     errprint(`1')errprint(`2',`3
+     ')
+     error->12 3
+     =>
+
+   A trailing newline is _not_ printed automatically, so it should be
+supplied as part of the argument, as in the example.  Unfortunately, the
+exact output of 'errprint' is not very portable to other 'm4'
+implementations: POSIX requires that all arguments be printed, but some
+implementations of 'm4' only print the first.  Furthermore, some BSD
+implementations always append a newline for each 'errprint' call,
+regardless of whether the last argument already had one, and POSIX is
+silent on whether this is acceptable.
+
+
+File: m4.info,  Node: Location,  Next: M4exit,  Prev: Errprint,  Up: Miscellaneous
+
+14.2 Printing current location
+==============================
+
+To make it possible to specify the location of an error, three utility
+builtins exist:
+
+ -- Builtin: __file__
+ -- Builtin: __line__
+ -- Builtin: __program__
+     Expand to the quoted name of the current input file, the current
+     input line number in that file, and the quoted name of the current
+     invocation of 'm4'.
+
+     errprint(__program__:__file__:__line__: `input error
+     ')
+     error->m4:stdin:1: input error
+     =>
+
+   Line numbers start at 1 for each file.  If the file was found due to
+the '-I' option or 'M4PATH' environment variable, that is reflected in
+the file name.  The syncline option ('-s', *note Invoking m4:
+Preprocessor features.), and the 'f' and 'l' flags of 'debugmode' (*note
+Debug Levels::), also use this notion of current file and line.
+Redefining the three location macros has no effect on syncline, debug,
+warning, or error message output.
+
+   This example reuses the file 'incl.m4' mentioned earlier (*note
+Include::):
+
+     $ m4 -I examples
+     define(`foo', ``$0' called at __file__:__line__')
+     =>
+     foo
+     =>foo called at stdin:2
+     include(`incl.m4')
+     =>Include file start
+     =>foo called at examples/incl.m4:2
+     =>Include file end
+     =>
+
+   The location of macros invoked during the rescanning of macro
+expansion text corresponds to the location in the file where the
+expansion was triggered, regardless of how many newline characters the
+expansion text contains.  As of GNU M4 1.4.8, the location of text
+wrapped with 'm4wrap' (*note M4wrap::) is the point at which the
+'m4wrap' was invoked.  Previous versions, however, behaved as though
+wrapped text came from line 0 of the file "".
+
+     define(`echo', `$@')
+     =>
+     define(`foo', `echo(__line__
+     __line__)')
+     =>
+     echo(__line__
+     __line__)
+     =>4
+     =>5
+     m4wrap(`foo
+     ')
+     =>
+     foo(errprint(__line__
+     __line__
+     ))
+     error->8
+     error->9
+     =>8
+     =>8
+     __line__
+     =>11
+     m4wrap(`__line__
+     ')
+     =>
+     ^D
+     =>12
+     =>6
+     =>6
+
+   The '__program__' macro behaves like '$0' in shell terminology.  If
+you invoke 'm4' through an absolute path or a link with a different
+spelling, rather than by relying on a 'PATH' search for plain 'm4', it
+will affect how '__program__' expands.  The intent is that you can use
+it to produce error messages with the same formatting that 'm4' produces
+internally.  It can also be used within 'syscmd' (*note Syscmd::) to
+pick the same version of 'm4' that is currently running, rather than
+whatever version of 'm4' happens to be first in 'PATH'.  It was first
+introduced in GNU M4 1.4.6.

+File: m4.info,  Node: M4exit,  Prev: Location,  Up: Miscellaneous
+
+14.3 Exiting from 'm4'
+======================
+
+If you need to exit from 'm4' before the entire input has been read, you
+can use 'm4exit':
+
+ -- Builtin: m4exit ([CODE = '0']
+     Causes 'm4' to exit, with exit status CODE.  If CODE is left out,
+     the exit status is zero.  If CODE cannot be parsed, or is outside
+     the range of 0 to 255, the exit status is one.  No further input is
+     read, and all wrapped and diverted text is discarded.
+
+     m4wrap(`This text is lost due to `m4exit'.')
+     =>
+     divert(`1') So is this.
+     divert
+     =>
+     m4exit And this is never read.
+
+   A common use of this is to abort processing:
+
+ -- Composite: fatal_error (MESSAGE)
+     Abort processing with an error message and non-zero status.  Prefix
+     MESSAGE with details about where the error occurred, and print the
+     resulting string to standard error.
+
+     define(`fatal_error',
+            `errprint(__program__:__file__:__line__`: fatal error: $*
+     ')m4exit(`1')')
+     =>
+     fatal_error(`this is a BAD one, buster')
+     error->m4:stdin:4: fatal error: this is a BAD one, buster
+
+   After this macro call, 'm4' will exit with exit status 1.  This macro
+is only intended for error exits, since the normal exit procedures are
+not followed, i.e., diverted text is not undiverted, and saved text
+(*note M4wrap::) is not reread.  (This macro could be made more robust
+to earlier versions of 'm4'.  You should try to see if you can find
+weaknesses and correct them; or *note Answers: Improved fatal_error.).
+
+   Note that it is still possible for the exit status to be different
+than what was requested by 'm4exit'.  If 'm4' detects some other error,
+such as a write error on standard output, the exit status will be
+non-zero even if 'm4exit' requested zero.
+
+   If standard input is seekable, then the file will be positioned at
+the next unread character.  If it is a pipe or other non-seekable file,
+then there are no guarantees how much data 'm4' might have read into
+buffers, and thus discarded.

+15 Fast loading of frozen state
+*******************************
+
+Some bigger 'm4' applications may be built over a common base containing
+hundreds of definitions and other costly initializations.  Usually, the
+common base is kept in one or more declarative files, which files are
+listed on each 'm4' invocation prior to the user's input file, or else
+each input file uses 'include'.
+
+   Reading the common base of a big application, over and over again,
+may be time consuming.  GNU 'm4' offers some machinery to speed up the
+start of an application using lengthy common bases.

+
+
+File: m4.info,  Node: Using frozen files,  Next: Frozen file format,  Up: Frozen files
+
+15.1 Using frozen files
+=======================
+
+Suppose a user has a library of 'm4' initializations in 'base.m4', which
+is then used with multiple input files:
+
+     $ m4 base.m4 input1.m4
+     $ m4 base.m4 input2.m4
+     $ m4 base.m4 input3.m4
+
+   Rather than spending time parsing the fixed contents of 'base.m4'
+every time, the user might rather execute:
+
+     $ m4 -F base.m4f base.m4
+
+once, and further execute, as often as needed:
+
+     $ m4 -R base.m4f input1.m4
+     $ m4 -R base.m4f input2.m4
+     $ m4 -R base.m4f input3.m4
+
+with the varying input.  The first call, containing the '-F' option,
+only reads and executes file 'base.m4', defining various application
+macros and computing other initializations.  Once the input file
+'base.m4' has been completely processed, GNU 'm4' produces in 'base.m4f'
+a "frozen" file, that is, a file which contains a kind of snapshot of
+the 'm4' internal state.
+
+   Later calls, containing the '-R' option, are able to reload the
+internal state of 'm4', from 'base.m4f', _prior_ to reading any other
+input files.  This means instead of starting with a virgin copy of 'm4',
+input will be read after having effectively recovered the effect of a
+prior run.  In our example, the effect is the same as if file 'base.m4'
+has been read anew.  However, this effect is achieved a lot faster.
+
+   Only one frozen file may be created or read in any one 'm4'
+invocation.  It is not possible to recover two frozen files at once.
+However, frozen files may be updated incrementally, through using '-R'
+and '-F' options simultaneously.  For example, if some care is taken,
+the command:
+
+     $ m4 file1.m4 file2.m4 file3.m4 file4.m4
+
+could be broken down in the following sequence, accumulating the same
+output:
+
+     $ m4 -F file1.m4f file1.m4
+     $ m4 -R file1.m4f -F file2.m4f file2.m4
+     $ m4 -R file2.m4f -F file3.m4f file3.m4
+     $ m4 -R file3.m4f file4.m4
+
+   Some care is necessary because not every effort has been made for
+this to work in all cases.  In particular, the trace attribute of macros
+is not handled, nor the current setting of 'changeword'.  Currently,
+'m4wrap' and 'sysval' also have problems.  Also, interactions for some
+options of 'm4', being used in one call and not in the next, have not
+been fully analyzed yet.  On the other end, you may be confident that
+stacks of 'pushdef' definitions are handled correctly, as well as
+undefined or renamed builtins, and changed strings for quotes or
+comments.  And future releases of GNU M4 will improve on the utility of
+frozen files.
+
+   When an 'm4' run is to be frozen, the automatic undiversion which
+takes place at end of execution is inhibited.  Instead, all positively
+numbered diversions are saved into the frozen file.  The active
+diversion number is also transmitted.
+
+   A frozen file to be reloaded need not reside in the current
+directory.  It is looked up the same way as an 'include' file (*note
+Search Path::).
+
+   If the frozen file was generated with a newer version of 'm4', and
+contains directives that an older 'm4' cannot parse, attempting to load
+the frozen file with option '-R' will cause 'm4' to exit with status 63
+to indicate version mismatch.
+

+File: m4.info,  Node: Frozen file format,  Prev: Using frozen files,  Up: Frozen files
+
+15.2 Frozen file format
+=======================
+
+Frozen files are sharable across architectures.  It is safe to write a
+frozen file on one machine and read it on another, given that the second
+machine uses the same or newer version of GNU 'm4'.  It is conventional,
+but not required, to give a frozen file the suffix of '.m4f'.
+
+   These are simple (editable) text files, made up of directives, each
+starting with a capital letter and ending with a newline (<NL>).
+Wherever a directive is expected, the character '#' introduces a comment
+line; empty lines are also ignored if they are not part of an embedded
+string.  In the following descriptions, each LEN refers to the length of
+the corresponding strings STR in the next line of input.  Numbers are
+always expressed in decimal.  There are no escape characters.  The
+directives are:
+
+'C LEN1 , LEN2 <NL> STR1 STR2 <NL>'
+     Uses STR1 and STR2 as the begin-comment and end-comment strings.
+     If omitted, then '#' and <NL> are the comment delimiters.
+
+'D NUMBER, LEN <NL> STR <NL>'
+     Selects diversion NUMBER, making it current, then copy STR in the
+     current diversion.  NUMBER may be a negative number for a
+     non-existing diversion.  To merely specify an active selection, use
+     this command with an empty STR.  With 0 as the diversion NUMBER,
+     STR will be issued on standard output at reload time.  GNU 'm4'
+     will not produce the 'D' directive with non-zero length for
+     diversion 0, but this can be done with manual edits.  This
+     directive may appear more than once for the same diversion, in
+     which case the diversion is the concatenation of the various uses.

+16 Compatibility with other versions of 'm4'
+********************************************
+
+This chapter describes the many of the differences between this
+implementation of 'm4', and of other implementations found under UNIX,
+such as System V Release 4, Solaris, and BSD flavors.  In particular, it
+lists the known differences and extensions to POSIX. However, the list
+is not necessarily comprehensive.
+
+   At the time of this writing, POSIX 2001 (also known as IEEE Std
+1003.1-2001) is the latest standard, although a new version of POSIX is
+under development and includes several proposals for modifying what 'm4'
+is required to do.  The requirements for 'm4' are shared between SUSv3
+and POSIX, and can be viewed at
+<http://www.opengroup.org/onlinepubs/000095399/utilities/m4.html>.

+
+16.1 Extensions in GNU M4
+=========================
+
+This version of 'm4' contains a few facilities that do not exist in
+System V 'm4'.  These extra facilities are all suppressed by using the
+'-G' command line option (*note Invoking m4: Limits control.), unless
+overridden by other command line options.
+
+   * In the '$N' notation for macro arguments, N can contain several
+     digits, while the System V 'm4' only accepts one digit.  This
+     allows macros in GNU 'm4' to take any number of arguments, and not
+     only nine (*note Arguments::).
+
+     This means that 'define(`foo', `$11')' is ambiguous between
+     implementations.  To portably choose between grabbing the first
+     parameter and appending 1 to the expansion, or grabbing the
+     eleventh parameter, you can do the following:
+
+          define(`a1', `A1')
+          =>
+          dnl First argument, concatenated with 1
+          define(`_1', `$1')define(`first1', `_1($@)1')
+          =>
+          dnl Eleventh argument, portable
+          define(`_9', `$9')define(`eleventh', `_9(shift(shift($@)))')
+          =>
+          dnl Eleventh argument, GNU style
+          define(`Eleventh', `$11')
+          =>
+          first1(`a', `b', `c', `d', `e', `f', `g', `h', `i', `j', `k')
+          =>A1
+          eleventh(`a', `b', `c', `d', `e', `f', `g', `h', `i', `j', `k')
+          =>k
+          Eleventh(`a', `b', `c', `d', `e', `f', `g', `h', `i', `j', `k')
+          =>k
+
+     Also see the 'argn' macro (*note Shift::).
+
+   * The 'divert' (*note Divert::) macro can manage more than 9
+     diversions.  GNU 'm4' treats all positive numbers as valid
+     diversions, rather than discarding diversions greater than 9.
+
+   * Files included with 'include' and 'sinclude' are sought in a user
+     specified search path, if they are not found in the working
+     directory.  The search path is specified by the '-I' option and the
+     'M4PATH' environment variable (*note Search Path::).
+
+   * Arguments to 'undivert' can be non-numeric, in which case the named
+     file will be included uninterpreted in the output (*note
+     Undivert::).
+
+   * Formatted output is supported through the 'format' builtin, which
+     is modeled after the C library function 'printf' (*note Format::).
+
+   * Searches and text substitution through basic regular expressions
+     are supported by the 'regexp' (*note Regexp::) and 'patsubst'
+     (*note Patsubst::) builtins.  Some BSD implementations use extended
+     regular expressions instead.
+
+   * The output of shell commands can be read into 'm4' with 'esyscmd'
+     (*note Esyscmd::).
+
+   * There is indirect access to any builtin macro with 'builtin' (*note
+     Builtin::).
+
+   * Macros can be called indirectly through 'indir' (*note Indir::).
+
+   * The name of the program, the current input file, and the current
+     input line number are accessible through the builtins
+     '__program__', '__file__', and '__line__' (*note Location::).
+
+   * The format of the output from 'dumpdef' and macro tracing can be
+     controlled with 'debugmode' (*note Debug Levels::).
+
+   * The destination of trace and debug output can be controlled with
+     'debugfile' (*note Debug Output::).
+
+   * The 'maketemp' (*note Mkstemp::) macro behaves like 'mkstemp',
+     creating a new file with a unique name on every invocation, rather
+     than following the insecure behavior of replacing the trailing 'X'
+     characters with the 'm4' process id.
+
+   * POSIX only requires support for the command line options '-s',
+     '-D', and '-U', so all other options accepted by GNU M4 are
+     extensions.  *Note Invoking m4::, for a description of these
+     options.
+
+     The debugging and tracing facilities in GNU 'm4' are much more
+     extensive than in most other versions of 'm4'.

+
+16.2 Facilities in System V 'm4' not in GNU 'm4'
+================================================
+
+The version of 'm4' from System V contains a few facilities that have
+not been implemented in GNU 'm4' yet.  Additionally, POSIX requires some
+behaviors that GNU 'm4' has not implemented yet.  Relying on these
+behaviors is non-portable, as a future release of GNU 'm4' may change.
+
+   * POSIX requires support for multiple arguments to 'defn', without
+     any clarification on how 'defn' behaves when one of the multiple
+     arguments names a builtin.  System V 'm4' and some other
+     implementations allow mixing builtins and text macros into a single
+     macro.  GNU 'm4' only supports joining multiple text arguments,
+     although a future implementation may lift this restriction to
+     behave more like System V.  The only portable way to join text
+     macros with builtins is via helper macros and implicit
+     concatenation of macro results.
+
+   * POSIX requires an application to exit with non-zero status if it
+     wrote an error message to stderr.  This has not yet been
+     consistently implemented for the various builtins that are required
+     to issue an error (such as 'eval' (*note Eval::) when an argument
+     cannot be parsed).
+
+   * Some traditional implementations only allow reading standard input
+     once, but GNU 'm4' correctly handles multiple instances of '-' on
+     the command line.
+
+   * POSIX requires 'm4wrap' (*note M4wrap::) to act in FIFO (first-in,
+     first-out) order, but GNU 'm4' currently uses LIFO order.
+     Furthermore, POSIX states that only the first argument to 'm4wrap'
+     is saved for later evaluation, but GNU 'm4' saves and processes all
+     arguments, with output separated by spaces.
+
+   * POSIX states that builtins that require arguments, but are called
+     without arguments, have undefined behavior.  Traditional
+     implementations simply behave as though empty strings had been
+     passed.  For example, 'a`'define`'b' would expand to 'ab'.  But GNU
+     'm4' ignores certain builtins if they have missing arguments,
+     giving 'adefineb' for the above example.
+
+   * Traditional implementations handle 'define(`f',`1')' (*note
+     Define::) by undefining the entire stack of previous definitions,
+     and if doing 'undefine(`f')' first.  GNU 'm4' replaces just the top
+     definition on the stack, as if doing 'popdef(`f')' followed by
+     'pushdef(`f',`1')'.  POSIX allows either behavior.
+
+   * POSIX 2001 requires 'syscmd' (*note Syscmd::) to evaluate command
+     output for macro expansion, but this was a mistake that is
+     anticipated to be corrected in the next version of POSIX. GNU 'm4'
+     follows traditional behavior in 'syscmd' where output is not
+     rescanned, and provides the extension 'esyscmd' that does scan the
+     output.
+
+   * At one point, POSIX required 'changequote(ARG)' (*note
+     Changequote::) to use newline as the close quote, but this was a
+     bug, and the next version of POSIX is anticipated to state that
+     using empty strings or just one argument is unspecified.
+     Meanwhile, the GNU 'm4' behavior of treating an empty end-quote
+     delimiter as ''' is not portable, as Solaris treats it as repeating
+     the start-quote delimiter, and BSD treats it as leaving the
+     previous end-quote delimiter unchanged.  For predictable results,
+     never call changequote with just one argument, or with empty
+     strings for arguments.
+
+   * At one point, POSIX required 'changecom(ARG,)' (*note Changecom::)
+     to make it impossible to end a comment, but this is a bug, and the
+     next version of POSIX is anticipated to state that using empty
+     strings is unspecified.  Meanwhile, the GNU 'm4' behavior of
+     treating an empty end-comment delimiter as newline is not portable,
+     as BSD treats it as leaving the previous end-comment delimiter
+     unchanged.  It is also impossible in BSD implementations to disable
+     comments, even though that is required by POSIX. For predictable
+     results, never call changecom with empty strings for arguments.
+
+   * Most implementations of 'm4' give macros a higher precedence than
+     comments when parsing, meaning that if the start delimiter given to
+     'changecom' (*note Changecom::) starts with a macro name, comments
+     are effectively disabled.  POSIX does not specify what the
+     precedence is, so this version of GNU 'm4' parser recognizes
+     comments, then macros, then quoted strings.
+
+   * Traditional implementations allow argument collection, but not
+     string and comment processing, to span file boundaries.  Thus, if
+     'a.m4' contains 'len(', and 'b.m4' contains 'abc)', 'm4 a.m4 b.m4'
+     outputs '3' with traditional 'm4', but gives an error message that
+     the end of file was encountered inside a macro with GNU 'm4'.  On
+     the other hand, traditional implementations do end of file
+     processing for files included with 'include' or 'sinclude' (*note
+     Include::), while GNU 'm4' seamlessly integrates the content of
+     those files.  Thus 'include(`a.m4')include(`b.m4')' will output '3'
+     instead of giving an error.
+
+   * Traditional 'm4' treats 'traceon' (*note Trace::) without arguments
+     as a global variable, independent of named macro tracing.  Also,
+     once a macro is undefined, named tracing of that macro is lost.  On
+     the other hand, when GNU 'm4' encounters 'traceon' without
+     arguments, it turns tracing on for all existing definitions at the
+     time, but does not trace future definitions; 'traceoff' without
+     arguments turns tracing off for all definitions regardless of
+     whether they were also traced by name; and tracing by name, such as
+     with '-tfoo' at the command line or 'traceon(`foo')' in the input,
+     is an attribute that is preserved even if the macro is currently
+     undefined.
+
+     Additionally, while POSIX requires trace output, it makes no
+     demands on the formatting of that output.  Parsing trace output is
+     not guaranteed to be reliable, even between different releases of
+     GNU M4; however, the intent is that any future changes in trace
+     output will only occur under the direction of additional
+     'debugmode' flags (*note Debug Levels::).
+
+   * POSIX requires 'eval' (*note Eval::) to treat all operators with
+     the same precedence as C.  However, earlier versions of GNU 'm4'
+     followed the traditional behavior of other 'm4' implementations,
+     where bitwise and logical negation ('~' and '!') have lower
+     precedence than equality operators; and where equality operators
+     ('==' and '!=') had the same precedence as relational operators
+     (such as '<').  Use explicit parentheses to ensure proper
+     precedence.  As extensions to POSIX, GNU 'm4' gives well-defined
+     semantics to operations that C leaves undefined, such as when
+     overflow occurs, when shifting negative numbers, or when performing
+     division by zero.  POSIX also requires '=' to cause an error, but
+     many traditional implementations allowed it as an alias for '=='.
+
+   * POSIX 2001 requires 'translit' (*note Translit::) to treat each
+     character of the second and third arguments literally.  However, it
+     is anticipated that the next version of POSIX will allow the GNU
+     'm4' behavior of treating '-' as a range operator.
+
+   * POSIX requires 'm4' to honor the locale environment variables of
+     'LANG', 'LC_ALL', 'LC_CTYPE', 'LC_MESSAGES', and 'NLSPATH', but
+     this has not yet been implemented in GNU 'm4'.
+
+   * POSIX states that only unquoted leading newlines and blanks (that
+     is, space and tab) are ignored when collecting macro arguments.
+     However, this appears to be a bug in POSIX, since most traditional
+     implementations also ignore all whitespace (formfeed, carriage
+     return, and vertical tab).  GNU 'm4' follows tradition and ignores
+     all leading unquoted whitespace.
+
+   * A strictly-compliant POSIX client is not allowed to use
+     command-line arguments not specified by POSIX. However, since this
+     version of M4 ignores 'POSIXLY_CORRECT' and enables the option
+     '--gnu' by default (*note Invoking m4: Limits control.), a client
+     desiring to be strictly compliant has no way to disable GNU
+     extensions that conflict with POSIX when directly invoking the
+     compiled 'm4'.  A future version of 'GNU' M4 will honor the
+     environment variable 'POSIXLY_CORRECT', implicitly enabling
+     '--traditional' if it is set, in order to allow a
+     strictly-compliant client.  In the meantime, a client needing
+     strict POSIX compliance can use the workaround of invoking a shell
+     script wrapper, where the wrapper then adds '--traditional' to the
+     arguments passed to the compiled 'm4'.

+
+16.3 Other incompatibilities
+============================
+
+There are a few other incompatibilities between this implementation of
+'m4', and the System V version.
+
+   * GNU 'm4' implements sync lines differently from System V 'm4', when
+     text is being diverted.  GNU 'm4' outputs the sync lines when the
+     text is being diverted, and System V 'm4' when the diverted text is
+     being brought back.
+
+     The problem is which lines and file names should be attached to
+     text that is being, or has been, diverted.  System V 'm4' regards
+     all the diverted text as being generated by the source line
+     containing the 'undivert' call, whereas GNU 'm4' regards the
+     diverted text as being generated at the time it is diverted.
+
+     The sync line option is used mostly when using 'm4' as a front end
+     to a compiler.  If a diverted line causes a compiler error, the
+     error messages should most probably refer to the place where the
+     diversion was made, and not where it was inserted again.
+
+          divert(2)2
+          divert(1)1
+          divert`'0
+          =>#line 3 "stdin"
+          =>0
+          ^D
+          =>#line 2 "stdin"
+          =>1
+          =>#line 1 "stdin"
+          =>2
+
+     The current 'm4' implementation has a limitation that the syncline
+     output at the start of each diversion occurs no matter what, even
+     if the previous diversion did not end with a newline.  This goes
+     contrary to the claim that synclines appear on a line by
+     themselves, so this limitation may be corrected in a future version
+     of 'm4'.  In the meantime, when using '-s', it is wisest to make
+     sure all diversions end with newline.
+
+   * GNU 'm4' makes no attempt at prohibiting self-referential
+     definitions like:
+
+          define(`x', `x')
+          =>
+          define(`x', `x ')
+          =>
+
+     There is nothing inherently wrong with defining 'x' to return 'x'.
+     The wrong thing is to expand 'x' unquoted, because that would cause
+     an infinite rescan loop.  In 'm4', one might use macros to hold
+     strings, as we do for variables in other programming languages,
+     further checking them with:
+
+          ifelse(defn(`HOLDER'), `VALUE', ...)
+
+     In cases like this one, an interdiction for a macro to hold its own
+     name would be a useless limitation.  Of course, this leaves more
+     rope for the GNU 'm4' user to hang himself!  Rescanning hangs may
+     be avoided through careful programming, a little like for endless
+     loops in traditional programming languages.

+17.1 Solution for 'exch'
+========================
+
+The 'exch' macro (*note Arguments::) as presented requires clients to
+double quote their arguments.  A nicer definition, which lets clients
+follow the rule of thumb of one level of quoting per level of
+parentheses, involves adding quotes in the definition of 'exch', as
+follows:
+
+     define(`exch', ``$2', `$1'')
+     =>
+     define(exch(`expansion text', `macro'))

+
+17.2 Solution for 'forloop'
+===========================
+
+The 'forloop' macro (*note Forloop::) as presented earlier can go into
+an infinite loop if given an iterator that is not parsed as a macro
+name.  It does not do any sanity checking on its numeric bounds, and
+only permits decimal numbers for bounds.  Here is an improved version,
+shipped as 'm4-1.4.17/examples/forloop2.m4'; this version also optimizes
+overhead by calling four macros instead of six per iteration (excluding
+those in TEXT), by not dereferencing the ITERATOR in the helper
+'_forloop'.

+     error->m4:stdin:6: bad expression in eval (bad input): (a) <= (b)
+     =>
+
+   One other change to notice is that the improved version used '_$0'
+rather than '_foreach' to invoke the helper routine.  In general, this
+is a good practice to follow, because then the set of macros can be
+uniformly transformed.  The following example shows a transformation
+that doubles the current quoting and appends a suffix '2' to each
+transformed macro.  If 'foreach' refers to the literal '_foreach', then
+'foreach2' invokes '_foreach' instead of the intended '_foreach2', and
+the mixing of quoting paradigms leads to an infinite recursion loop in
+this example.

+assigning a variable then invoking or dereferencing it, it is possible
+to pass the current iterator value as a single argument.  Coupled with
+'curry' if other arguments are needed (*note Composition::), or with
+helper macros if the argument is needed in more than one place in the
+expansion, the output can be generated with three, rather than four,
+macros of overhead per iteration.  Notice how the file
+'m4-1.4.17/examples/forloop3.m4' rearranges the arguments of the helper
+'_forloop' to take two arguments that are placed around the current
+value.  By splitting a balanced set of parantheses across multiple
+arguments, the helper macro can now be shared by 'forloop' and the new
+'forloop_arg'.

+17.3 Solution for 'foreach'
+===========================
+
+The 'foreach' and 'foreachq' macros (*note Foreach::) as presented
+earlier each have flaws.  First, we will examine and fix the quadratic
+behavior of 'foreachq':
+
+     $ m4 -I examples
+     include(`foreachq.m4')
+     =>
+     traceon(`shift')debugmode(`aq')
+     =>
+     foreachq(`x', ``1', `2', `3', `4'', `x
+     ')dnl
+     =>1
+     error->m4trace: -3- shift(`1', `2', `3', `4')
+     error->m4trace: -2- shift(`1', `2', `3', `4')
+     =>2
+     error->m4trace: -4- shift(`1', `2', `3', `4')
+     error->m4trace: -3- shift(`2', `3', `4')
+     error->m4trace: -3- shift(`1', `2', `3', `4')
+     error->m4trace: -2- shift(`2', `3', `4')
+     =>3
+     error->m4trace: -5- shift(`1', `2', `3', `4')
+     error->m4trace: -4- shift(`2', `3', `4')
+     error->m4trace: -3- shift(`3', `4')
+     error->m4trace: -4- shift(`1', `2', `3', `4')
+     error->m4trace: -3- shift(`2', `3', `4')
+     error->m4trace: -2- shift(`3', `4')
+     =>4
+     error->m4trace: -6- shift(`1', `2', `3', `4')
+     error->m4trace: -5- shift(`2', `3', `4')
+     error->m4trace: -4- shift(`3', `4')
+     error->m4trace: -3- shift(`4')
+
+   Each successive iteration was adding more quoted 'shift' invocations,
+and the entire list contents were passing through every iteration.  In
+general, when recursing, it is a good idea to make the recursion use
+fewer arguments, rather than adding additional quoted uses of 'shift'.
+By doing so, 'm4' uses less memory, invokes fewer macros, is less likely
+to run into machine limits, and most importantly, performs faster.  The
+fixed version of 'foreachq' can be found in
+'m4-1.4.17/examples/foreachq2.m4':
+
+     $ m4 -I examples
+     include(`foreachq2.m4')
+     =>
+     undivert(`foreachq2.m4')dnl
+     =>include(`quote.m4')dnl
+     =>divert(`-1')
+     =># foreachq(x, `item_1, item_2, ..., item_n', stmt)
+     =>#   quoted list, improved version
+     =>define(`foreachq', `pushdef(`$1')_$0($@)popdef(`$1')')
+     =>define(`_arg1q', ``$1'')
+     =>define(`_rest', `ifelse(`$#', `1', `', `dquote(shift($@))')')
+     =>define(`_foreachq', `ifelse(`$2', `', `',
+     =>  `define(`$1', _arg1q($2))$3`'$0(`$1', _rest($2), `$3')')')
+     =>divert`'dnl
+     traceon(`shift')debugmode(`aq')
+     =>
+     foreachq(`x', ``1', `2', `3', `4'', `x
+     ')dnl
+     =>1
+     error->m4trace: -3- shift(`1', `2', `3', `4')
+     =>2
+     error->m4trace: -3- shift(`2', `3', `4')
+     =>3
+     error->m4trace: -3- shift(`3', `4')
+     =>4
+
+   Note that the fixed version calls unquoted helper macros in
+'_foreachq' to trim elements immediately; those helper macros in turn
+must re-supply the layer of quotes lost in the macro invocation.
+Contrast the use of '_arg1q', which quotes the first list element, with
+'_arg1' of the earlier implementation that returned the first list
+element directly.  Additionally, by calling the helper method
+immediately, the 'defn(`ITERATOR')' no longer contains unexpanded
+macros.
+
+   The astute m4 programmer might notice that the solution above still
+uses more memory and macro invocations, and thus more time, than
+strictly necessary.  Note that '$2', which contains an arbitrarily long
+quoted list, is expanded and rescanned three times per iteration of
+'_foreachq'.  Furthermore, every iteration of the algorithm effectively
+unboxes then reboxes the list, which costs a couple of macro
+invocations.  It is possible to rewrite the algorithm for a bit more
+speed by swapping the order of the arguments to '_foreachq' in order to
+operate on an unboxed list in the first place, and by using the
+fixed-length '$#' instead of an arbitrary length list as the key to end
+recursion.  The result is an overhead of six macro invocations per loop
+(excluding any macros in TEXT), instead of eight.  This alternative
+approach is available as 'm4-1.4.17/examples/foreach3.m4':
+
+     $ m4 -I examples
+     include(`foreachq3.m4')

+
+   In the current version of M4, every instance of '$@' is rescanned as
+it is encountered.  Thus, the 'foreachq3.m4' alternative uses much less
+memory than 'foreachq2.m4', and executes as much as 10% faster, since
+each iteration encounters fewer '$@'.  However, the implementation of
+rescanning every byte in '$@' is quadratic in the number of bytes
+scanned (for example, making the broken version in 'foreachq.m4' cubic,
+rather than quadratic, in behavior).  A future release of M4 will
+improve the underlying implementation by reusing results of previous
+scans, so that both styles of 'foreachq' can become linear in the number
+of bytes scanned.  Notice how the implementation injects an empty
+argument prior to expanding '$2' within 'foreachq'; the helper macro
+'_foreachq' then ignores the third argument altogether, and ends
+recursion when there are three arguments left because there was nothing
+left to pass through 'shift'.  Thus, each iteration only needs one
+'ifelse', rather than the two conditionals used in the version from
+'foreachq2.m4'.
+
+   So far, all of the implementations of 'foreachq' presented have been
+quadratic with M4 1.4.x.  But 'forloop' is linear, because each
+iteration parses a constant amount of arguments.  So, it is possible to
+design a variant that uses 'forloop' to do the iteration, then uses '$@'
+only once at the end, giving a linear result even with older M4
+implementations.  This implementation relies on the GNU extension that
+'$10' expands to the tenth argument rather than the first argument
+concatenated with '0'.  The trick is to define an intermediate macro
+that repeats the text 'm4_define(`$1', `$N')$2`'', with 'n' set to
+successive integers corresponding to each argument.  The helper macro
+'_foreachq_' is needed in order to generate the literal sequences such
+as '$1' into the intermediate macro, rather than expanding them as the
+arguments of '_foreachq'.  With this approach, no 'shift' calls are even
+needed!  Even though there are seven macros of overhead per iteration
+instead of six in 'foreachq3.m4', the linear scaling is apparent at
+relatively small list sizes.  However, this approach will need
+adjustment when a future version of M4 follows POSIX by no longer
+treating '$10' as the tenth argument; the anticipation is that '${10}'
+can be used instead, although that alternative syntax is not yet
+supported.

+   For yet another approach, the improved version of 'foreach',
+available in 'm4-1.4.17/examples/foreach2.m4', simply overquotes the
+arguments to '_foreach' to begin with, using 'dquote_elt'.  Then
+'_foreach' can just use '_arg1' to remove the extra layer of quoting
+that was added up front:

+     $ m4 -I examples

+     =>  `define(`$1', _arg1$2)$3`'$0(`$1', (dquote(shift$2)), `$3')')')

+     =>3
+     error->m4trace: -3- shift(``3'', ``4'')
+     =>4
+     error->m4trace: -3- shift(``4'')
+
+   It is likewise possible to write a variant of 'foreach' that performs
+in linear time on M4 1.4.x; the easiest method is probably writing a
+version of 'foreach' that unboxes its list, then invokes '_foreachq' as
+previously defined in 'foreachq4.m4'.
+
+   In summary, recursion over list elements is trickier than it appeared
+at first glance, but provides a powerful idiom within 'm4' processing.
+As a final demonstration, both list styles are now able to handle
+several scenarios that would wreak havoc on one or both of the original
+implementations.  This points out one other difference between the list
+styles.  'foreach' evaluates unquoted list elements only once, in
+preparation for calling '_foreach', similary for 'foreachq' as provided
+by 'foreachq3.m4' or 'foreachq4.m4'.  But 'foreachq', as provided by
+'foreachq2.m4', evaluates unquoted list elements twice while visiting
+the first list element, once in '_arg1q' and once in '_rest'.  When
+deciding which list style to use, one must take into account whether
+repeating the side effects of unquoted list elements will have any
+detrimental effects.

+17.4 Solution for 'copy'
+========================
+
+The macro 'copy' presented above is unable to handle builtin tokens with
+M4 1.4.x, because it tries to pass the builtin token through the macro
+'curry', where it is silently flattened to an empty string (*note
+Composition::).  Rather than using the problematic 'curry' to work
+around the limitation that 'stack_foreach' expects to invoke a macro
+that takes exactly one argument, we can write a new macro that lets us
+form the exact two-argument 'pushdef' call sequence needed, so that we
+are no longer passing a builtin token through a text macro.
+
+ -- Composite: stack_foreach_sep (MACRO, PRE, POST, SEP)
+ -- Composite: stack_foreach_sep_lifo (MACRO, PRE, POST, SEP)
+     For each of the 'pushdef' definitions associated with MACRO, expand
+     the sequence 'PRE`'definition`'POST'.  Additionally, expand SEP
+     between definitions.  'stack_foreach_sep' visits the oldest
+     definition first, while 'stack_foreach_sep_lifo' visits the current
+     definition first.  The expansion may dereference MACRO, but should
+     not modify it.  There are a few special macros, such as 'defn',
+     which cannot be used as the MACRO parameter.
+
+   Note that 'stack_foreach(`MACRO', `ACTION')' is equivalent to
+'stack_foreach_sep(`MACRO', `ACTION(', `)')'.  By supplying explicit
+parentheses, split among the PRE and POST arguments to
+'stack_foreach_sep', it is now possible to construct macro calls with
+more than one argument, without passing builtin tokens through a macro
+call.  It is likewise possible to directly reference the stack
+definitions without a macro call, by leaving PRE and POST empty.  Thus,
+in addition to fixing 'copy' on builtin tokens, it also executes with
+fewer macro invocations.
+
+   The new macro also adds a separator that is only output after the
+first iteration of the helper '_stack_reverse_sep', implemented by
+prepending the original SEP to PRE and omitting a SEP argument in
+subsequent iterations.  Note that the empty string that separates SEP
+from PRE is provided as part of the fourth argument when originally
+calling '_stack_reverse_sep', and not by writing '$4`'$3' as the third
+argument in the recursive call; while the other approach would give the
+same output, it does so at the expense of increasing the argument size
+on each iteration of '_stack_reverse_sep', which results in quadratic
+instead of linear execution time.  The improved stack walking macros are

+FIFO or LIFO order regardless of the underlying M4 implementation, share
+a bug when dealing with wrapped text that looks like parameter
+expansion.  Note how the invocation of 'm4wrapN' interprets these
+parameters, while using the builtin preserves them for their intended
+use.
+
+     $ m4 -I examples
+     include(`wraplifo.m4')
+     =>
+     m4wrap(`define(`foo', ``$0:'-$1-$*-$#-')foo(`a', `b')
+     ')
+     =>
+     builtin(`m4wrap', ``'define(`bar', ``$0:'-$1-$*-$#-')bar(`a', `b')
+     ')
+     =>
+     ^D
+     =>bar:-a-a,b-2-
+     =>m4wrap0:---0-
+
+   Additionally, the computation of '_m4wrap_level' and creation of
+multiple 'm4wrapN' placeholders in the original examples is more
+expensive in time and memory than strictly necessary.  Notice how the
+improved version grabs the wrapped text via 'defn' to avoid parameter
+expansion, then undefines '_m4wrap_text', before stripping a level of
+quotes with '_arg1' to expand the text.  That way, each level of
+wrapping reuses the single placeholder, which starts each nesting level
+in an undefined state.
+
+   Finally, it is worth emulating the GNU M4 extension of saving all
+arguments to 'm4wrap', separated by a space, rather than saving just the
+first argument.  This is done with the 'join' macro documented
+previously (*note Shift::).  The improved LIFO example is shipped as
+'m4-1.4.17/examples/wraplifo2.m4', and can easily be converted to a FIFO
+solution by swapping the adjacent invocations of 'joinall' and 'defn'.

+===============================
+
+The 'cleardivert' macro (*note Cleardivert::) cannot, as it stands, be
+called without arguments to clear all pending diversions.  That is
+because using undivert with an empty string for an argument is different
+than using it with no arguments at all.  Compare the earlier definition
+with one that takes the number of arguments into account:
+
+     define(`cleardivert',

+
+17.7 Solution for 'capitalize'
+==============================
+
+The 'capitalize' macro (*note Patsubst::) as presented earlier does not
+allow clients to follow the quoting rule of thumb.  Consider the three
+macros 'active', 'Active', and 'ACTIVE', and the difference between
+calling 'capitalize' with the expansion of a macro, expanding the result
+of a case change, and changing the case of a double-quoted string:
+
+     $ m4 -I examples
+     include(`capitalize.m4')dnl
+     define(`active', `act1, ive')dnl
+     define(`Active', `Act2, Ive')dnl
+     define(`ACTIVE', `ACT3, IVE')dnl
+     upcase(active)
+     =>ACT1,IVE
+     upcase(`active')
+     =>ACT3, IVE
+     upcase(``active'')
+     =>ACTIVE
+     downcase(ACTIVE)
+     =>act3,ive
+     downcase(`ACTIVE')
+     =>act1, ive
+     downcase(``ACTIVE'')
+     =>active
+     capitalize(active)
+     =>Act1
+     capitalize(`active')
+     =>Active
+     capitalize(``active'')
+     =>_capitalize(`active')
+     define(`A', `OOPS')
+     =>
+     capitalize(active)
+     =>OOPSct1
+     capitalize(`active')
+     =>OOPSctive
+
+   First, when 'capitalize' is called with more than one argument, it
+was throwing away later arguments, whereas 'upcase' and 'downcase' used
+'$*' to collect them all.  The fix is simple: use '$*' consistently.
+
+   Next, with single-quoting, 'capitalize' outputs a single character, a
+set of quotes, then the rest of the characters, making it impossible to
+invoke 'Active' after the fact, and allowing the alternate macro 'A' to
+interfere.  Here, the solution is to use additional quoting in the
+helper macros, then pass the final over-quoted output string through
+'_arg1' to remove the extra quoting and finally invoke the concatenated
+portions as a single string.
+
+   Finally, when passed a double-quoted string, the nested macro
+'_capitalize' is never invoked because it ended up nested inside quotes.
+This one is the toughest to fix.  In short, we have no idea how many
+levels of quotes are in effect on the substring being altered by
+'patsubst'.  If the replacement string cannot be expressed entirely in
+terms of literal text and backslash substitutions, then we need a
+mechanism to guarantee that the helper macros are invoked outside of
+quotes.  In other words, this sounds like a job for 'changequote' (*note
+Changequote::).  By changing the active quoting characters, we can
+guarantee that replacement text injected by 'patsubst' always occurs in
+the middle of a string that has exactly one level of over-quoting using
+alternate quotes; so the replacement text closes the quoted string,
+invokes the helper macros, then reopens the quoted string.  In turn,
+that means the replacement text has unbalanced quotes, necessitating
+another round of 'changequote'.
+
+   In the fixed version below, (also shipped as
+'m4-1.4.17/examples/capitalize2.m4'), 'capitalize' uses the alternate
+quotes of '<<[' and ']>>' (the longer strings are chosen so as to be
+less likely to appear in the text being converted).  The helpers
+'_to_alt' and '_from_alt' merely reduce the number of characters
+required to perform a 'changequote', since the definition changes twice.
+The outermost pair means that 'patsubst' and '_capitalize_alt' are
+invoked with alternate quoting; the innermost pair is used so that the
+third argument to 'patsubst' can contain an unbalanced ']>>'/'<<[' pair.
+Note that 'upcase' and 'downcase' must be redefined as '_upcase_alt' and
+'_downcase_alt', since they contain nested quotes but are invoked with
+the alternate quoting scheme in effect.
+
+     $ m4 -I examples
+     include(`capitalize2.m4')dnl
+     define(`active', `act1, ive')dnl
+     define(`Active', `Act2, Ive')dnl

+17.8 Solution for 'fatal_error'
+===============================
+
+The 'fatal_error' macro (*note M4exit::) is not robust to versions of
+GNU M4 earlier than 1.4.8, where invoking '__file__' (*note Location::)
+inside 'm4wrap' would result in an empty string, and '__line__' resulted
+in '0' even though all files start at line 1.  Furthermore, versions
+earlier than 1.4.6 did not support the '__program__' macro.  If you want
+'fatal_error' to work across the entire 1.4.x release series, a better
+implementation would be:
+
+     define(`fatal_error',
+       `errprint(ifdef(`__program__', `__program__', ``m4'')'dnl
+     `:ifelse(__line__, `0', `',

+
+     Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+
+     Everyone is permitted to copy and distribute verbatim copies of this
+     license document, but changing it is not allowed.
+
+Preamble
+========
+
+The GNU General Public License is a free, copyleft license for software
+and other kinds of works.
+
+   The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+   When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+   To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+   For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+   Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+   For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+   Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+   Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+   The precise terms and conditions for copying, distribution and
+modification follow.
+
+TERMS AND CONDITIONS
+====================
+
+  0. Definitions.
+
+     "This License" refers to version 3 of the GNU General Public
+     License.
+
+     "Copyright" also means copyright-like laws that apply to other
+     kinds of works, such as semiconductor masks.
+
+     "The Program" refers to any copyrightable work licensed under this
+     License.  Each licensee is addressed as "you".  "Licensees" and
+     "recipients" may be individuals or organizations.
+
+     To "modify" a work means to copy from or adapt all or part of the
+     work in a fashion requiring copyright permission, other than the
+     making of an exact copy.  The resulting work is called a "modified
+     version" of the earlier work or a work "based on" the earlier work.
+
+     A "covered work" means either the unmodified Program or a work
+     based on the Program.
+
+     To "propagate" a work means to do anything with it that, without
+     permission, would make you directly or secondarily liable for
+     infringement under applicable copyright law, except executing it on
+     a computer or modifying a private copy.  Propagation includes
+     copying, distribution (with or without modification), making
+     available to the public, and in some countries other activities as
+     well.
+
+     To "convey" a work means any kind of propagation that enables other
+     parties to make or receive copies.  Mere interaction with a user
+     through a computer network, with no transfer of a copy, is not
+     conveying.
+
+     An interactive user interface displays "Appropriate Legal Notices"
+     to the extent that it includes a convenient and prominently visible
+     feature that (1) displays an appropriate copyright notice, and (2)
+     tells the user that there is no warranty for the work (except to
+     the extent that warranties are provided), that licensees may convey
+     the work under this License, and how to view a copy of this
+     License.  If the interface presents a list of user commands or
+     options, such as a menu, a prominent item in the list meets this
+     criterion.
+
+  1. Source Code.
+
+     The "source code" for a work means the preferred form of the work
+     for making modifications to it.  "Object code" means any non-source
+     form of a work.
+
+     A "Standard Interface" means an interface that either is an
+     official standard defined by a recognized standards body, or, in
+     the case of interfaces specified for a particular programming
+     language, one that is widely used among developers working in that
+     language.
+
+     The "System Libraries" of an executable work include anything,
+     other than the work as a whole, that (a) is included in the normal
+     form of packaging a Major Component, but which is not part of that
+     Major Component, and (b) serves only to enable use of the work with
+     that Major Component, or to implement a Standard Interface for
+     which an implementation is available to the public in source code
+     form.  A "Major Component", in this context, means a major
+     essential component (kernel, window system, and so on) of the
+     specific operating system (if any) on which the executable work
+     runs, or a compiler used to produce the work, or an object code
+     interpreter used to run it.
+
+     The "Corresponding Source" for a work in object code form means all
+     the source code needed to generate, install, and (for an executable
+     work) run the object code and to modify the work, including scripts
+     to control those activities.  However, it does not include the
+     work's System Libraries, or general-purpose tools or generally
+     available free programs which are used unmodified in performing
+     those activities but which are not part of the work.  For example,
+     Corresponding Source includes interface definition files associated
+     with source files for the work, and the source code for shared
+     libraries and dynamically linked subprograms that the work is
+     specifically designed to require, such as by intimate data
+     communication or control flow between those subprograms and other
+     parts of the work.
+
+     The Corresponding Source need not include anything that users can
+     regenerate automatically from other parts of the Corresponding
+     Source.
+
+     The Corresponding Source for a work in source code form is that
+     same work.
+
+  2. Basic Permissions.
+
+     All rights granted under this License are granted for the term of
+     copyright on the Program, and are irrevocable provided the stated
+     conditions are met.  This License explicitly affirms your unlimited
+     permission to run the unmodified Program.  The output from running
+     a covered work is covered by this License only if the output, given
+     its content, constitutes a covered work.  This License acknowledges
+     your rights of fair use or other equivalent, as provided by
+     copyright law.
+
+     You may make, run and propagate covered works that you do not
+     convey, without conditions so long as your license otherwise
+     remains in force.  You may convey covered works to others for the
+     sole purpose of having them make modifications exclusively for you,
+     or provide you with facilities for running those works, provided
+     that you comply with the terms of this License in conveying all
+     material for which you do not control copyright.  Those thus making
+     or running the covered works for you must do so exclusively on your
+     behalf, under your direction and control, on terms that prohibit
+     them from making any copies of your copyrighted material outside
+     their relationship with you.
+
+     Conveying under any other circumstances is permitted solely under
+     the conditions stated below.  Sublicensing is not allowed; section
+     10 makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+     No covered work shall be deemed part of an effective technological
+     measure under any applicable law fulfilling obligations under
+     article 11 of the WIPO copyright treaty adopted on 20 December
+     1996, or similar laws prohibiting or restricting circumvention of
+     such measures.
+
+     When you convey a covered work, you waive any legal power to forbid
+     circumvention of technological measures to the extent such
+     circumvention is effected by exercising rights under this License
+     with respect to the covered work, and you disclaim any intention to
+     limit operation or modification of the work as a means of
+     enforcing, against the work's users, your or third parties' legal
+     rights to forbid circumvention of technological measures.
+
+  4. Conveying Verbatim Copies.
+
+     You may convey verbatim copies of the Program's source code as you
+     receive it, in any medium, provided that you conspicuously and
+     appropriately publish on each copy an appropriate copyright notice;
+     keep intact all notices stating that this License and any
+     non-permissive terms added in accord with section 7 apply to the
+     code; keep intact all notices of the absence of any warranty; and
+     give all recipients a copy of this License along with the Program.
+
+     You may charge any price or no price for each copy that you convey,
+     and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+     You may convey a work based on the Program, or the modifications to
+     produce it from the Program, in the form of source code under the
+     terms of section 4, provided that you also meet all of these
+     conditions:
+
+       a. The work must carry prominent notices stating that you
+          modified it, and giving a relevant date.
+
+       b. The work must carry prominent notices stating that it is
+          released under this License and any conditions added under
+          section 7.  This requirement modifies the requirement in
+          section 4 to "keep intact all notices".
+
+       c. You must license the entire work, as a whole, under this
+          License to anyone who comes into possession of a copy.  This
+          License will therefore apply, along with any applicable
+          section 7 additional terms, to the whole of the work, and all
+          its parts, regardless of how they are packaged.  This License
+          gives no permission to license the work in any other way, but
+          it does not invalidate such permission if you have separately
+          received it.
+
+       d. If the work has interactive user interfaces, each must display
+          Appropriate Legal Notices; however, if the Program has
+          interactive interfaces that do not display Appropriate Legal
+          Notices, your work need not make them do so.
+
+     A compilation of a covered work with other separate and independent
+     works, which are not by their nature extensions of the covered
+     work, and which are not combined with it such as to form a larger
+     program, in or on a volume of a storage or distribution medium, is
+     called an "aggregate" if the compilation and its resulting
+     copyright are not used to limit the access or legal rights of the
+     compilation's users beyond what the individual works permit.
+     Inclusion of a covered work in an aggregate does not cause this
+     License to apply to the other parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+     You may convey a covered work in object code form under the terms
+     of sections 4 and 5, provided that you also convey the
+     machine-readable Corresponding Source under the terms of this
+     License, in one of these ways:
+
+       a. Convey the object code in, or embodied in, a physical product
+          (including a physical distribution medium), accompanied by the
+          Corresponding Source fixed on a durable physical medium
+          customarily used for software interchange.
+
+       b. Convey the object code in, or embodied in, a physical product
+          (including a physical distribution medium), accompanied by a
+          written offer, valid for at least three years and valid for as
+          long as you offer spare parts or customer support for that
+          product model, to give anyone who possesses the object code
+          either (1) a copy of the Corresponding Source for all the
+          software in the product that is covered by this License, on a
+          durable physical medium customarily used for software
+          interchange, for a price no more than your reasonable cost of
+          physically performing this conveying of source, or (2) access
+          to copy the Corresponding Source from a network server at no
+          charge.
+
+       c. Convey individual copies of the object code with a copy of the
+          written offer to provide the Corresponding Source.  This
+          alternative is allowed only occasionally and noncommercially,
+          and only if you received the object code with such an offer,
+          in accord with subsection 6b.
+
+       d. Convey the object code by offering access from a designated
+          place (gratis or for a charge), and offer equivalent access to
+          the Corresponding Source in the same way through the same
+          place at no further charge.  You need not require recipients
+          to copy the Corresponding Source along with the object code.
+          If the place to copy the object code is a network server, the
+          Corresponding Source may be on a different server (operated by
+          you or a third party) that supports equivalent copying
+          facilities, provided you maintain clear directions next to the
+          object code saying where to find the Corresponding Source.
+          Regardless of what server hosts the Corresponding Source, you
+          remain obligated to ensure that it is available for as long as
+          needed to satisfy these requirements.
+
+       e. Convey the object code using peer-to-peer transmission,
+          provided you inform other peers where the object code and
+          Corresponding Source of the work are being offered to the
+          general public at no charge under subsection 6d.
+
+     A separable portion of the object code, whose source code is
+     excluded from the Corresponding Source as a System Library, need
+     not be included in conveying the object code work.
+
+     A "User Product" is either (1) a "consumer product", which means
+     any tangible personal property which is normally used for personal,
+     family, or household purposes, or (2) anything designed or sold for
+     incorporation into a dwelling.  In determining whether a product is
+     a consumer product, doubtful cases shall be resolved in favor of
+     coverage.  For a particular product received by a particular user,
+     "normally used" refers to a typical or common use of that class of
+     product, regardless of the status of the particular user or of the
+     way in which the particular user actually uses, or expects or is
+     expected to use, the product.  A product is a consumer product
+     regardless of whether the product has substantial commercial,
+     industrial or non-consumer uses, unless such uses represent the
+     only significant mode of use of the product.
+
+     "Installation Information" for a User Product means any methods,
+     procedures, authorization keys, or other information required to
+     install and execute modified versions of a covered work in that
+     User Product from a modified version of its Corresponding Source.
+     The information must suffice to ensure that the continued
+     functioning of the modified object code is in no case prevented or
+     interfered with solely because modification has been made.
+
+     If you convey an object code work under this section in, or with,
+     or specifically for use in, a User Product, and the conveying
+     occurs as part of a transaction in which the right of possession
+     and use of the User Product is transferred to the recipient in
+     perpetuity or for a fixed term (regardless of how the transaction
+     is characterized), the Corresponding Source conveyed under this
+     section must be accompanied by the Installation Information.  But
+     this requirement does not apply if neither you nor any third party
+     retains the ability to install modified object code on the User
+     Product (for example, the work has been installed in ROM).
+
+     The requirement to provide Installation Information does not
+     include a requirement to continue to provide support service,
+     warranty, or updates for a work that has been modified or installed
+     by the recipient, or for the User Product in which it has been
+     modified or installed.  Access to a network may be denied when the
+     modification itself materially and adversely affects the operation
+     of the network or violates the rules and protocols for
+     communication across the network.
+
+     Corresponding Source conveyed, and Installation Information
+     provided, in accord with this section must be in a format that is
+     publicly documented (and with an implementation available to the
+     public in source code form), and must require no special password
+     or key for unpacking, reading or copying.
+
+  7. Additional Terms.
+
+     "Additional permissions" are terms that supplement the terms of
+     this License by making exceptions from one or more of its
+     conditions.  Additional permissions that are applicable to the
+     entire Program shall be treated as though they were included in
+     this License, to the extent that they are valid under applicable
+     law.  If additional permissions apply only to part of the Program,
+     that part may be used separately under those permissions, but the
+     entire Program remains governed by this License without regard to
+     the additional permissions.
+
+     When you convey a copy of a covered work, you may at your option
+     remove any additional permissions from that copy, or from any part
+     of it.  (Additional permissions may be written to require their own
+     removal in certain cases when you modify the work.)  You may place
+     additional permissions on material, added by you to a covered work,
+     for which you have or can give appropriate copyright permission.
+
+     Notwithstanding any other provision of this License, for material
+     you add to a covered work, you may (if authorized by the copyright
+     holders of that material) supplement the terms of this License with
+     terms:
+
+       a. Disclaiming warranty or limiting liability differently from
+          the terms of sections 15 and 16 of this License; or
+
+       b. Requiring preservation of specified reasonable legal notices
+          or author attributions in that material or in the Appropriate
+          Legal Notices displayed by works containing it; or
+
+       c. Prohibiting misrepresentation of the origin of that material,
+          or requiring that modified versions of such material be marked
+          in reasonable ways as different from the original version; or
+
+       d. Limiting the use for publicity purposes of names of licensors
+          or authors of the material; or
+
+       e. Declining to grant rights under trademark law for use of some
+          trade names, trademarks, or service marks; or
+
+       f. Requiring indemnification of licensors and authors of that
+          material by anyone who conveys the material (or modified
+          versions of it) with contractual assumptions of liability to
+          the recipient, for any liability that these contractual
+          assumptions directly impose on those licensors and authors.
+
+     All other non-permissive additional terms are considered "further
+     restrictions" within the meaning of section 10.  If the Program as
+     you received it, or any part of it, contains a notice stating that
+     it is governed by this License along with a term that is a further
+     restriction, you may remove that term.  If a license document
+     contains a further restriction but permits relicensing or conveying
+     under this License, you may add to a covered work material governed
+     by the terms of that license document, provided that the further
+     restriction does not survive such relicensing or conveying.
+
+     If you add terms to a covered work in accord with this section, you
+     must place, in the relevant source files, a statement of the
+     additional terms that apply to those files, or a notice indicating
+     where to find the applicable terms.
+
+     Additional terms, permissive or non-permissive, may be stated in
+     the form of a separately written license, or stated as exceptions;
+     the above requirements apply either way.
+
+  8. Termination.
+
+     You may not propagate or modify a covered work except as expressly
+     provided under this License.  Any attempt otherwise to propagate or
+     modify it is void, and will automatically terminate your rights
+     under this License (including any patent licenses granted under the
+     third paragraph of section 11).
+
+     However, if you cease all violation of this License, then your
+     license from a particular copyright holder is reinstated (a)
+     provisionally, unless and until the copyright holder explicitly and
+     finally terminates your license, and (b) permanently, if the
+     copyright holder fails to notify you of the violation by some
+     reasonable means prior to 60 days after the cessation.
+
+     Moreover, your license from a particular copyright holder is
+     reinstated permanently if the copyright holder notifies you of the
+     violation by some reasonable means, this is the first time you have
+     received notice of violation of this License (for any work) from
+     that copyright holder, and you cure the violation prior to 30 days
+     after your receipt of the notice.
+
+     Termination of your rights under this section does not terminate
+     the licenses of parties who have received copies or rights from you
+     under this License.  If your rights have been terminated and not
+     permanently reinstated, you do not qualify to receive new licenses
+     for the same material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+     You are not required to accept this License in order to receive or
+     run a copy of the Program.  Ancillary propagation of a covered work
+     occurring solely as a consequence of using peer-to-peer
+     transmission to receive a copy likewise does not require
+     acceptance.  However, nothing other than this License grants you
+     permission to propagate or modify any covered work.  These actions
+     infringe copyright if you do not accept this License.  Therefore,
+     by modifying or propagating a covered work, you indicate your
+     acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+     Each time you convey a covered work, the recipient automatically
+     receives a license from the original licensors, to run, modify and
+     propagate that work, subject to this License.  You are not
+     responsible for enforcing compliance by third parties with this
+     License.
+
+     An "entity transaction" is a transaction transferring control of an
+     organization, or substantially all assets of one, or subdividing an
+     organization, or merging organizations.  If propagation of a
+     covered work results from an entity transaction, each party to that
+     transaction who receives a copy of the work also receives whatever
+     licenses to the work the party's predecessor in interest had or
+     could give under the previous paragraph, plus a right to possession
+     of the Corresponding Source of the work from the predecessor in
+     interest, if the predecessor has it or can get it with reasonable
+     efforts.
+
+     You may not impose any further restrictions on the exercise of the
+     rights granted or affirmed under this License.  For example, you
+     may not impose a license fee, royalty, or other charge for exercise
+     of rights granted under this License, and you may not initiate
+     litigation (including a cross-claim or counterclaim in a lawsuit)
+     alleging that any patent claim is infringed by making, using,
+     selling, offering for sale, or importing the Program or any portion
+     of it.
+
+  11. Patents.
+
+     A "contributor" is a copyright holder who authorizes use under this
+     License of the Program or a work on which the Program is based.
+     The work thus licensed is called the contributor's "contributor
+     version".
+
+     A contributor's "essential patent claims" are all patent claims
+     owned or controlled by the contributor, whether already acquired or
+     hereafter acquired, that would be infringed by some manner,
+     permitted by this License, of making, using, or selling its
+     contributor version, but do not include claims that would be
+     infringed only as a consequence of further modification of the
+     contributor version.  For purposes of this definition, "control"
+     includes the right to grant patent sublicenses in a manner
+     consistent with the requirements of this License.
+
+     Each contributor grants you a non-exclusive, worldwide,
+     royalty-free patent license under the contributor's essential
+     patent claims, to make, use, sell, offer for sale, import and
+     otherwise run, modify and propagate the contents of its contributor
+     version.
+
+     In the following three paragraphs, a "patent license" is any
+     express agreement or commitment, however denominated, not to
+     enforce a patent (such as an express permission to practice a
+     patent or covenant not to sue for patent infringement).  To "grant"
+     such a patent license to a party means to make such an agreement or
+     commitment not to enforce a patent against the party.
+
+     If you convey a covered work, knowingly relying on a patent
+     license, and the Corresponding Source of the work is not available
+     for anyone to copy, free of charge and under the terms of this
+     License, through a publicly available network server or other
+     readily accessible means, then you must either (1) cause the
+     Corresponding Source to be so available, or (2) arrange to deprive
+     yourself of the benefit of the patent license for this particular
+     work, or (3) arrange, in a manner consistent with the requirements
+     of this License, to extend the patent license to downstream
+     recipients.  "Knowingly relying" means you have actual knowledge
+     that, but for the patent license, your conveying the covered work
+     in a country, or your recipient's use of the covered work in a
+     country, would infringe one or more identifiable patents in that
+     country that you have reason to believe are valid.
+
+     If, pursuant to or in connection with a single transaction or
+     arrangement, you convey, or propagate by procuring conveyance of, a
+     covered work, and grant a patent license to some of the parties
+     receiving the covered work authorizing them to use, propagate,
+     modify or convey a specific copy of the covered work, then the
+     patent license you grant is automatically extended to all
+     recipients of the covered work and works based on it.
+
+     A patent license is "discriminatory" if it does not include within
+     the scope of its coverage, prohibits the exercise of, or is
+     conditioned on the non-exercise of one or more of the rights that
+     are specifically granted under this License.  You may not convey a
+     covered work if you are a party to an arrangement with a third
+     party that is in the business of distributing software, under which
+     you make payment to the third party based on the extent of your
+     activity of conveying the work, and under which the third party
+     grants, to any of the parties who would receive the covered work
+     from you, a discriminatory patent license (a) in connection with
+     copies of the covered work conveyed by you (or copies made from
+     those copies), or (b) primarily for and in connection with specific
+     products or compilations that contain the covered work, unless you
+     entered into that arrangement, or that patent license was granted,
+     prior to 28 March 2007.
+
+     Nothing in this License shall be construed as excluding or limiting
+     any implied license or other defenses to infringement that may
+     otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+     If conditions are imposed on you (whether by court order, agreement
+     or otherwise) that contradict the conditions of this License, they
+     do not excuse you from the conditions of this License.  If you
+     cannot convey a covered work so as to satisfy simultaneously your
+     obligations under this License and any other pertinent obligations,
+     then as a consequence you may not convey it at all.  For example,
+     if you agree to terms that obligate you to collect a royalty for
+     further conveying from those to whom you convey the Program, the
+     only way you could satisfy both those terms and this License would
+     be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+     Notwithstanding any other provision of this License, you have
+     permission to link or combine any covered work with a work licensed
+     under version 3 of the GNU Affero General Public License into a
+     single combined work, and to convey the resulting work.  The terms
+     of this License will continue to apply to the part which is the
+     covered work, but the special requirements of the GNU Affero
+     General Public License, section 13, concerning interaction through
+     a network will apply to the combination as such.
+
+  14. Revised Versions of this License.
+
+     The Free Software Foundation may publish revised and/or new
+     versions of the GNU General Public License from time to time.  Such
+     new versions will be similar in spirit to the present version, but
+     may differ in detail to address new problems or concerns.
+
+     Each version is given a distinguishing version number.  If the
+     Program specifies that a certain numbered version of the GNU
+     General Public License "or any later version" applies to it, you
+     have the option of following the terms and conditions either of
+     that numbered version or of any later version published by the Free
+     Software Foundation.  If the Program does not specify a version
+     number of the GNU General Public License, you may choose any
+     version ever published by the Free Software Foundation.
+
+     If the Program specifies that a proxy can decide which future
+     versions of the GNU General Public License can be used, that
+     proxy's public statement of acceptance of a version permanently
+     authorizes you to choose that version for the Program.
+
+     Later license versions may give you additional or different
+     permissions.  However, no additional obligations are imposed on any
+     author or copyright holder as a result of your choosing to follow a
+     later version.
+
+  15. Disclaimer of Warranty.
+
+     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+     APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE
+     COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS"
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+     INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+     MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE
+     RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
+     SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+     NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+     WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
+     AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+     DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+     CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
+     THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
+     BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+     PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF
+     THE POSSIBILITY OF SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+     If the disclaimer of warranty and limitation of liability provided
+     above cannot be given local legal effect according to their terms,
+     reviewing courts shall apply local law that most closely
+     approximates an absolute waiver of all civil liability in
+     connection with the Program, unless a warranty or assumption of
+     liability accompanies a copy of the Program in return for a fee.
+
+END OF TERMS AND CONDITIONS
+===========================
+
+How to Apply These Terms to Your New Programs
+=============================================
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+   To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+     ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES.
+     Copyright (C) YEAR NAME OF AUTHOR
+
+     This program is free software: you can redistribute it and/or modify
+     it under the terms of the GNU General Public License as published by
+     the Free Software Foundation, either version 3 of the License, or (at
+     your option) any later version.
+
+     This program is distributed in the hope that it will be useful, but
+     WITHOUT ANY WARRANTY; without even the implied warranty of
+     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+     General Public License for more details.
+
+     You should have received a copy of the GNU General Public License
+     along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+   Also add information on how to contact you by electronic and paper
+mail.
+
+   If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+     PROGRAM Copyright (C) YEAR NAME OF AUTHOR
+     This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
+     This is free software, and you are welcome to redistribute it
+     under certain conditions; type 'show c' for details.
+
+   The hypothetical commands 'show w' and 'show c' should show the
+appropriate parts of the General Public License.  Of course, your
+program's commands might be different; for a GUI interface, you would
+use an "about box".
+
+   You should also get your employer (if you work as a programmer) or
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  For more information on this, and how to apply and follow
+the GNU GPL, see <http://www.gnu.org/licenses/>.
+
+   The GNU General Public License does not permit incorporating your
+program into proprietary programs.  If your program is a subroutine
+library, you may consider it more useful to permit linking proprietary
+applications with the library.  If this is what you want to do, use the
+GNU Lesser General Public License instead of this License.  But first,
+please read <http://www.gnu.org/philosophy/why-not-lgpl.html>.

+1 Overview of `make'
+********************
+
+The `make' utility automatically determines which pieces of a large
+program need to be recompiled, and issues commands to recompile them.
+This manual describes GNU `make', which was implemented by Richard
+Stallman and Roland McGrath.  Development since Version 3.76 has been
+handled by Paul D. Smith.
+
+   GNU `make' conforms to section 6.2 of `IEEE Standard 1003.2-1992'
+(POSIX.2).  
+
+   Our examples show C programs, since they are most common, but you
+can use `make' with any programming language whose compiler can be run
+with a shell command.  Indeed, `make' is not limited to programs.  You
+can use it to describe any task where some files must be updated
+automatically from others whenever the others change.

+
+Preparing and Running Make
+==========================
+
+   To prepare to use `make', you must write a file called the
+"makefile" that describes the relationships among files in your program
+and provides commands for updating each file.  In a program, typically,
+the executable file is updated from object files, which are in turn
+made by compiling source files.
+
+   Once a suitable makefile exists, each time you change some source
+files, this simple shell command:
+
+     make
+
+suffices to perform all necessary recompilations.  The `make' program
+uses the makefile data base and the last-modification times of the
+files to decide which of the files need to be updated.  For each of
+those files, it issues the recipes recorded in the data base.
+
+   You can provide command line arguments to `make' to control which
+files should be recompiled, or how.  *Note How to Run `make': Running.

+
+1.1 How to Read This Manual
+===========================
+
+If you are new to `make', or are looking for a general introduction,
+read the first few sections of each chapter, skipping the later
+sections.  In each chapter, the first few sections contain introductory
+or general information and the later sections contain specialized or
+technical information.  The exception is the second chapter, *note An
+Introduction to Makefiles: Introduction, all of which is introductory.
+
+   If you are familiar with other `make' programs, see *note Features
+of GNU `make': Features, which lists the enhancements GNU `make' has,
+and *note Incompatibilities and Missing Features: Missing, which
+explains the few things GNU `make' lacks that others have.

+Reference::, and *note Special Targets::.

+
+1.2 Problems and Bugs
+=====================
+
+If you have problems with GNU `make' or think you've found a bug,
+please report it to the developers; we cannot promise to do anything but
+we might well want to fix it.
+
+   Before reporting a bug, make sure you've actually found a real bug.
+Carefully reread the documentation and see if it really says you can do
+what you're trying to do.  If it's not clear whether you should be able
+to do something or not, report that too; it's a bug in the
+documentation!
+
+   Before reporting a bug or trying to fix it yourself, try to isolate
+it to the smallest possible makefile that reproduces the problem.  Then
+send us the makefile and the exact results `make' gave you, including
+any error or warning messages.  Please don't paraphrase these messages:
+it's best to cut and paste them into your report.  When generating this
+small makefile, be sure to not use any non-free or unusual tools in
+your recipes: you can almost always emulate what such a tool would do
+with simple shell commands.  Finally, be sure to explain what you
+expected to occur; this will help us decide whether the problem was
+really in the documentation.
+
+   Once you have a precise problem you can report it in one of two ways.
+Either send electronic mail to:
+
+         bug-make@gnu.org
+
+or use our Web-based project management tool, at:
+
+         http://savannah.gnu.org/projects/make/
+
+In addition to the information above, please be careful to include the
+version number of `make' you are using.  You can get this information
+with the command `make --version'.  Be sure also to include the type of
+machine and operating system you are using.  One way to obtain this
+information is by looking at the final lines of output from the command
+`make --help'.

+
+2 An Introduction to Makefiles
+******************************
+
+You need a file called a "makefile" to tell `make' what to do.  Most
+often, the makefile tells `make' how to compile and link a program.  
+
+   In this chapter, we will discuss a simple makefile that describes
+how to compile and link a text editor which consists of eight C source
+files and three header files.  The makefile can also tell `make' how to
+run miscellaneous commands when explicitly asked (for example, to remove
+certain files as a clean-up operation).  To see a more complex example
+of a makefile, see *note Complex Makefile::.
+
+   When `make' recompiles the editor, each changed C source file must
+be recompiled.  If a header file has changed, each C source file that
+includes the header file must be recompiled to be safe.  Each
+compilation produces an object file corresponding to the source file.
+Finally, if any source file has been recompiled, all the object files,
+whether newly made or saved from previous compilations, must be linked
+together to produce the new executable editor.

+File: make.info,  Node: Rule Introduction,  Next: Simple Makefile,  Prev: Introduction,  Up: Introduction
+
+2.1 What a Rule Looks Like
+==========================
+
+A simple makefile consists of "rules" with the following shape:
+
+     TARGET ... : PREREQUISITES ...
+             RECIPE
+             ...
+             ...
+
+   A "target" is usually the name of a file that is generated by a
+program; examples of targets are executable or object files.  A target
+can also be the name of an action to carry out, such as `clean' (*note
+Phony Targets::).
+
+   A "prerequisite" is a file that is used as input to create the
+target.  A target often depends on several files.
+
+   A "recipe" is an action that `make' carries out.  A recipe may have
+more than one command, either on the same line or each on its own line.
+*Please note:* you need to put a tab character at the beginning of
+every recipe line!  This is an obscurity that catches the unwary.  If
+you prefer to prefix your recipes with a character other than tab, you
+can set the `.RECIPEPREFIX' variable to an alternate character (*note
+Special Variables::).
+
+   Usually a recipe is in a rule with prerequisites and serves to
+create a target file if any of the prerequisites change.  However, the
+rule that specifies a recipe for the target need not have
+prerequisites.  For example, the rule containing the delete command
+associated with the target `clean' does not have prerequisites.
+
+   A "rule", then, explains how and when to remake certain files which
+are the targets of the particular rule.  `make' carries out the recipe
+on the prerequisites to create or update the target.  A rule can also
+explain how and when to carry out an action.  *Note Writing Rules:
+Rules.
+
+   A makefile may contain other text besides rules, but a simple
+makefile need only contain rules.  Rules may look somewhat more
+complicated than shown in this template, but all fit the pattern more
+or less.
+

+File: make.info,  Node: Simple Makefile,  Next: How Make Works,  Prev: Rule Introduction,  Up: Introduction
+
+2.2 A Simple Makefile
+=====================
+
+Here is a straightforward makefile that describes the way an executable
+file called `edit' depends on eight object files which, in turn, depend
+on eight C source and three header files.
+
+   In this example, all the C files include `defs.h', but only those
+defining editing commands include `command.h', and only low level files
+that change the editor buffer include `buffer.h'.
+
+     edit : main.o kbd.o command.o display.o \
+            insert.o search.o files.o utils.o
+             cc -o edit main.o kbd.o command.o display.o \
+                        insert.o search.o files.o utils.o
+
+     main.o : main.c defs.h
+             cc -c main.c
+     kbd.o : kbd.c defs.h command.h
+             cc -c kbd.c
+     command.o : command.c defs.h command.h
+             cc -c command.c
+     display.o : display.c defs.h buffer.h
+             cc -c display.c
+     insert.o : insert.c defs.h buffer.h
+             cc -c insert.c
+     search.o : search.c defs.h buffer.h
+             cc -c search.c
+     files.o : files.c defs.h buffer.h command.h
+             cc -c files.c
+     utils.o : utils.c defs.h
+             cc -c utils.c
+     clean :
+             rm edit main.o kbd.o command.o display.o \
+                insert.o search.o files.o utils.o
+
+We split each long line into two lines using backslash-newline; this is
+like using one long line, but is easier to read.  
+
+   To use this makefile to create the executable file called `edit',
+type:
+
+     make
+
+   To use this makefile to delete the executable file and all the object
+files from the directory, type:
+
+     make clean
+
+   In the example makefile, the targets include the executable file
+`edit', and the object files `main.o' and `kbd.o'.  The prerequisites
+are files such as `main.c' and `defs.h'.  In fact, each `.o' file is
+both a target and a prerequisite.  Recipes include `cc -c main.c' and
+`cc -c kbd.c'.
+
+   When a target is a file, it needs to be recompiled or relinked if any
+of its prerequisites change.  In addition, any prerequisites that are
+themselves automatically generated should be updated first.  In this
+example, `edit' depends on each of the eight object files; the object
+file `main.o' depends on the source file `main.c' and on the header
+file `defs.h'.
+
+   A recipe may follow each line that contains a target and
+prerequisites.  These recipes say how to update the target file.  A tab
+character (or whatever character is specified by the `.RECIPEPREFIX'
+variable; *note Special Variables::) must come at the beginning of
+every line in the recipe to distinguish recipes from other lines in the
+makefile.  (Bear in mind that `make' does not know anything about how
+the recipes work.  It is up to you to supply recipes that will update
+the target file properly.  All `make' does is execute the recipe you
+have specified when the target file needs to be updated.)  
+
+   The target `clean' is not a file, but merely the name of an action.
+Since you normally do not want to carry out the actions in this rule,
+`clean' is not a prerequisite of any other rule.  Consequently, `make'
+never does anything with it unless you tell it specifically.  Note that
+this rule not only is not a prerequisite, it also does not have any
+prerequisites, so the only purpose of the rule is to run the specified
+recipe.  Targets that do not refer to files but are just actions are
+called "phony targets".  *Note Phony Targets::, for information about
+this kind of target.  *Note Errors in Recipes: Errors, to see how to
+cause `make' to ignore errors from `rm' or any other command.  
+
+
+File: make.info,  Node: How Make Works,  Next: Variables Simplify,  Prev: Simple Makefile,  Up: Introduction
+
+2.3 How `make' Processes a Makefile
+===================================
+
+By default, `make' starts with the first target (not targets whose
+names start with `.').  This is called the "default goal".  ("Goals"
+are the targets that `make' strives ultimately to update.    You can
+override this behavior using the command line (*note Arguments to
+Specify the Goals: Goals.) or with the `.DEFAULT_GOAL' special variable
+(*note Other Special Variables: Special Variables.).  
+
+   In the simple example of the previous section, the default goal is to
+update the executable program `edit'; therefore, we put that rule first.
+
+   Thus, when you give the command:
+
+     make
+
+`make' reads the makefile in the current directory and begins by
+processing the first rule.  In the example, this rule is for relinking
+`edit'; but before `make' can fully process this rule, it must process
+the rules for the files that `edit' depends on, which in this case are
+the object files.  Each of these files is processed according to its
+own rule.  These rules say to update each `.o' file by compiling its
+source file.  The recompilation must be done if the source file, or any
+of the header files named as prerequisites, is more recent than the
+object file, or if the object file does not exist.
+
+   The other rules are processed because their targets appear as
+prerequisites of the goal.  If some other rule is not depended on by the
+goal (or anything it depends on, etc.), that rule is not processed,
+unless you tell `make' to do so (with a command such as `make clean').
+
+   Before recompiling an object file, `make' considers updating its
+prerequisites, the source file and header files.  This makefile does not
+specify anything to be done for them--the `.c' and `.h' files are not
+the targets of any rules--so `make' does nothing for these files.  But
+`make' would update automatically generated C programs, such as those
+made by Bison or Yacc, by their own rules at this time.
+
+   After recompiling whichever object files need it, `make' decides
+whether to relink `edit'.  This must be done if the file `edit' does
+not exist, or if any of the object files are newer than it.  If an
+object file was just recompiled, it is now newer than `edit', so `edit'
+is relinked.  
+
+   Thus, if we change the file `insert.c' and run `make', `make' will
+compile that file to update `insert.o', and then link `edit'.  If we
+change the file `command.h' and run `make', `make' will recompile the
+object files `kbd.o', `command.o' and `files.o' and then link the file
+`edit'.
+
+
+File: make.info,  Node: Variables Simplify,  Next: make Deduces,  Prev: How Make Works,  Up: Introduction
+
+2.4 Variables Make Makefiles Simpler
+====================================
+
+In our example, we had to list all the object files twice in the rule
+for `edit' (repeated here):
+
+     edit : main.o kbd.o command.o display.o \
+                   insert.o search.o files.o utils.o
+             cc -o edit main.o kbd.o command.o display.o \
+                        insert.o search.o files.o utils.o
+
+   Such duplication is error-prone; if a new object file is added to the
+system, we might add it to one list and forget the other.  We can
+eliminate the risk and simplify the makefile by using a variable.
+"Variables" allow a text string to be defined once and substituted in
+multiple places later (*note How to Use Variables: Using Variables.).
+
+   It is standard practice for every makefile to have a variable named
+`objects', `OBJECTS', `objs', `OBJS', `obj', or `OBJ' which is a list
+of all object file names.  We would define such a variable `objects'
+with a line like this in the makefile:
+
+     objects = main.o kbd.o command.o display.o \
+               insert.o search.o files.o utils.o
+
+Then, each place we want to put a list of the object file names, we can
+substitute the variable's value by writing `$(objects)' (*note How to
+Use Variables: Using Variables.).
+
+   Here is how the complete simple makefile looks when you use a
+variable for the object files:
+
+     objects = main.o kbd.o command.o display.o \
+               insert.o search.o files.o utils.o
+
+     edit : $(objects)
+             cc -o edit $(objects)
+     main.o : main.c defs.h
+             cc -c main.c
+     kbd.o : kbd.c defs.h command.h
+             cc -c kbd.c
+     command.o : command.c defs.h command.h
+             cc -c command.c
+     display.o : display.c defs.h buffer.h
+             cc -c display.c
+     insert.o : insert.c defs.h buffer.h
+             cc -c insert.c
+     search.o : search.c defs.h buffer.h
+             cc -c search.c
+     files.o : files.c defs.h buffer.h command.h
+             cc -c files.c
+     utils.o : utils.c defs.h
+             cc -c utils.c
+     clean :
+             rm edit $(objects)
+
+
+File: make.info,  Node: make Deduces,  Next: Combine By Prerequisite,  Prev: Variables Simplify,  Up: Introduction
+
+2.5 Letting `make' Deduce the Recipes
+=====================================
+
+It is not necessary to spell out the recipes for compiling the
+individual C source files, because `make' can figure them out: it has an
+"implicit rule" for updating a `.o' file from a correspondingly named
+`.c' file using a `cc -c' command.  For example, it will use the recipe
+`cc -c main.c -o main.o' to compile `main.c' into `main.o'.  We can
+therefore omit the recipes from the rules for the object files.  *Note
+Using Implicit Rules: Implicit Rules.
+
+   When a `.c' file is used automatically in this way, it is also
+automatically added to the list of prerequisites.  We can therefore omit
+the `.c' files from the prerequisites, provided we omit the recipe.
+
+   Here is the entire example, with both of these changes, and a
+variable `objects' as suggested above:
+
+     objects = main.o kbd.o command.o display.o \
+               insert.o search.o files.o utils.o
+
+     edit : $(objects)
+             cc -o edit $(objects)
+
+     main.o : defs.h
+     kbd.o : defs.h command.h
+     command.o : defs.h command.h
+     display.o : defs.h buffer.h
+     insert.o : defs.h buffer.h
+     search.o : defs.h buffer.h
+     files.o : defs.h buffer.h command.h
+     utils.o : defs.h
+
+     .PHONY : clean
+     clean :
+             rm edit $(objects)
+
+This is how we would write the makefile in actual practice.  (The
+complications associated with `clean' are described elsewhere.  See
+*note Phony Targets::, and *note Errors in Recipes: Errors.)
+
+   Because implicit rules are so convenient, they are important.  You
+will see them used frequently.
+
+
+File: make.info,  Node: Combine By Prerequisite,  Next: Cleanup,  Prev: make Deduces,  Up: Introduction
+
+2.6 Another Style of Makefile
+=============================
+
+When the objects of a makefile are created only by implicit rules, an
+alternative style of makefile is possible.  In this style of makefile,
+you group entries by their prerequisites instead of by their targets.
+Here is what one looks like:
+
+     objects = main.o kbd.o command.o display.o \
+               insert.o search.o files.o utils.o
+
+     edit : $(objects)
+             cc -o edit $(objects)
+
+     $(objects) : defs.h
+     kbd.o command.o files.o : command.h
+     display.o insert.o search.o files.o : buffer.h
+
+Here `defs.h' is given as a prerequisite of all the object files;
+`command.h' and `buffer.h' are prerequisites of the specific object
+files listed for them.
+
+   Whether this is better is a matter of taste: it is more compact, but
+some people dislike it because they find it clearer to put all the
+information about each target in one place.
+
+
+File: make.info,  Node: Cleanup,  Prev: Combine By Prerequisite,  Up: Introduction
+
+2.7 Rules for Cleaning the Directory
+====================================
+
+Compiling a program is not the only thing you might want to write rules
+for.  Makefiles commonly tell how to do a few other things besides
+compiling a program: for example, how to delete all the object files
+and executables so that the directory is `clean'.
+
+   Here is how we could write a `make' rule for cleaning our example
+editor:
+
+     clean:
+             rm edit $(objects)
+
+   In practice, we might want to write the rule in a somewhat more
+complicated manner to handle unanticipated situations.  We would do
+this:
+
+     .PHONY : clean
+     clean :
+             -rm edit $(objects)
+
+This prevents `make' from getting confused by an actual file called
+`clean' and causes it to continue in spite of errors from `rm'.  (See
+*note Phony Targets::, and *note Errors in Recipes: Errors.)
+
+A rule such as this should not be placed at the beginning of the
+makefile, because we do not want it to run by default!  Thus, in the
+example makefile, we want the rule for `edit', which recompiles the
+editor, to remain the default goal.
+
+   Since `clean' is not a prerequisite of `edit', this rule will not
+run at all if we give the command `make' with no arguments.  In order
+to make the rule run, we have to type `make clean'.  *Note How to Run
+`make': Running.

+==========================
+
+Makefiles contain five kinds of things: "explicit rules", "implicit

+
+   * An "explicit rule" says when and how to remake one or more files,
+     called the rule's "targets".  It lists the other files that the
+     targets depend on, called the "prerequisites" of the target, and
+     may also give a recipe to use to create or update the targets.
+     *Note Writing Rules: Rules.
+
+   * An "implicit rule" says when and how to remake a class of files
+     based on their names.  It describes how a target may depend on a
+     file with a name similar to the target and gives a recipe to
+     create or update such a target.  *Note Using Implicit Rules:
+     Implicit Rules.
+
+   * A "variable definition" is a line that specifies a text string
+     value for a variable that can be substituted into the text later.
+     The simple makefile example shows a variable definition for
+     `objects' as a list of all object files (*note Variables Make
+     Makefiles Simpler: Variables Simplify.).
+
+   * A "directive" is an instruction for `make' to do something special
+     while reading the makefile.  These include:
+
+        * Reading another makefile (*note Including Other Makefiles:
+          Include.).
+
+        * Deciding (based on the values of variables) whether to use or
+          ignore a part of the makefile (*note Conditional Parts of
+          Makefiles: Conditionals.).
+
+        * Defining a variable from a verbatim string containing
+          multiple lines (*note Defining Multi-Line Variables:
+          Multi-Line.).
+
+   * `#' in a line of a makefile starts a "comment".  It and the rest
+     of the line are ignored, except that a trailing backslash not
+     escaped by another backslash will continue the comment across
+     multiple lines.  A line containing just a comment (with perhaps
+     spaces before it) is effectively blank, and is ignored.  If you
+     want a literal `#', escape it with a backslash (e.g., `\#').
+     Comments may appear on any line in the makefile, although they are
+     treated specially in certain situations.
+
+     You cannot use comments within variable references or function
+     calls: any instance of `#' will be treated literally (rather than
+     as the start of a comment) inside a variable reference or function
+     call.
+
+     Comments within a recipe are passed to the shell, just as with any
+     other recipe text.  The shell decides how to interpret it: whether
+     or not this is a comment is up to the shell.
+
+     Within a `define' directive, comments are not ignored during the
+     definition of the variable, but rather kept intact in the value of
+     the variable.  When the variable is expanded they will either be
+     treated as `make' comments or as recipe text, depending on the
+     context in which the variable is evaluated.

+
+3.2 What Name to Give Your Makefile
+===================================
+
+By default, when `make' looks for the makefile, it tries the following
+names, in order: `GNUmakefile', `makefile' and `Makefile'.  
+
+   Normally you should call your makefile either `makefile' or
+`Makefile'.  (We recommend `Makefile' because it appears prominently
+near the beginning of a directory listing, right near other important
+files such as `README'.)  The first name checked, `GNUmakefile', is not
+recommended for most makefiles.  You should use this name if you have a
+makefile that is specific to GNU `make', and will not be understood by
+other versions of `make'.  Other `make' programs look for `makefile' and
+`Makefile', but not `GNUmakefile'.
+
+   If `make' finds none of these names, it does not use any makefile.
+Then you must specify a goal with a command argument, and `make' will
+attempt to figure out how to remake it using only its built-in implicit
+rules.  *Note Using Implicit Rules: Implicit Rules.
+
+   If you want to use a nonstandard name for your makefile, you can
+specify the makefile name with the `-f' or `--file' option.  The
+arguments `-f NAME' or `--file=NAME' tell `make' to read the file NAME
+as the makefile.  If you use more than one `-f' or `--file' option, you
+can specify several makefiles.  All the makefiles are effectively
+concatenated in the order specified.  The default makefile names
+`GNUmakefile', `makefile' and `Makefile' are not checked automatically
+if you specify `-f' or `--file'.  
+

+File: make.info,  Node: Include,  Next: MAKEFILES Variable,  Prev: Makefile Names,  Up: Makefiles
+
+3.3 Including Other Makefiles
+=============================
+
+The `include' directive tells `make' to suspend reading the current
+makefile and read one or more other makefiles before continuing.  The
+directive is a line in the makefile that looks like this:
+
+     include FILENAMES...
+
+FILENAMES can contain shell file name patterns.  If FILENAMES is empty,
+nothing is included and no error is printed.  
+
+   Extra spaces are allowed and ignored at the beginning of the line,
+but the first character must not be a tab (or the value of
+`.RECIPEPREFIX')--if the line begins with a tab, it will be considered
+a recipe line.  Whitespace is required between `include' and the file
+names, and between file names; extra whitespace is ignored there and at
+the end of the directive.  A comment starting with `#' is allowed at
+the end of the line.  If the file names contain any variable or
+function references, they are expanded.  *Note How to Use Variables:
+Using Variables.
+
+   For example, if you have three `.mk' files, `a.mk', `b.mk', and
+`c.mk', and `$(bar)' expands to `bish bash', then the following
+expression
+
+     include foo *.mk $(bar)
+
+   is equivalent to
+
+     include foo a.mk b.mk c.mk bish bash
+
+   When `make' processes an `include' directive, it suspends reading of
+the containing makefile and reads from each listed file in turn.  When
+that is finished, `make' resumes reading the makefile in which the
+directive appears.
+
+   One occasion for using `include' directives is when several programs,
+handled by individual makefiles in various directories, need to use a
+common set of variable definitions (*note Setting Variables: Setting.)
+or pattern rules (*note Defining and Redefining Pattern Rules: Pattern
+Rules.).
+
+   Another such occasion is when you want to generate prerequisites from
+source files automatically; the prerequisites can be put in a file that
+is included by the main makefile.  This practice is generally cleaner
+than that of somehow appending the prerequisites to the end of the main
+makefile as has been traditionally done with other versions of `make'.
+*Note Automatic Prerequisites::.  
+
+   If the specified name does not start with a slash, and the file is
+not found in the current directory, several other directories are
+searched.  First, any directories you have specified with the `-I' or
+`--include-dir' option are searched (*note Summary of Options: Options
+Summary.).  Then the following directories (if they exist) are
+searched, in this order: `PREFIX/include' (normally `/usr/local/include'
+(1)) `/usr/gnu/include', `/usr/local/include', `/usr/include'.
+
+   If an included makefile cannot be found in any of these directories,
+a warning message is generated, but it is not an immediately fatal
+error; processing of the makefile containing the `include' continues.
+Once it has finished reading makefiles, `make' will try to remake any
+that are out of date or don't exist.  *Note How Makefiles Are Remade:
+Remaking Makefiles.  Only after it has tried to find a way to remake a
+makefile and failed, will `make' diagnose the missing makefile as a
+fatal error.
+
+   If you want `make' to simply ignore a makefile which does not exist
+or cannot be remade, with no error message, use the `-include'
+directive instead of `include', like this:
+
+     -include FILENAMES...
+
+   This acts like `include' in every way except that there is no error
+(not even a warning) if any of the FILENAMES (or any prerequisites of
+any of the FILENAMES) do not exist or cannot be remade.
+
+   For compatibility with some other `make' implementations, `sinclude'
+is another name for `-include'.

+
+3.4 The Variable `MAKEFILES'
+============================
+
+If the environment variable `MAKEFILES' is defined, `make' considers
+its value as a list of names (separated by whitespace) of additional
+makefiles to be read before the others.  This works much like the
+`include' directive: various directories are searched for those files
+(*note Including Other Makefiles: Include.).  In addition, the default
+goal is never taken from one of these makefiles (or any makefile
+included by them) and it is not an error if the files listed in
+`MAKEFILES' are not found.
+
+   The main use of `MAKEFILES' is in communication between recursive
+invocations of `make' (*note Recursive Use of `make': Recursion.).  It
+usually is not desirable to set the environment variable before a
+top-level invocation of `make', because it is usually better not to
+mess with a makefile from outside.  However, if you are running `make'
+without a specific makefile, a makefile in `MAKEFILES' can do useful
+things to help the built-in implicit rules work better, such as
+defining search paths (*note Directory Search::).
+
+   Some users are tempted to set `MAKEFILES' in the environment
+automatically on login, and program makefiles to expect this to be done.
+This is a very bad idea, because such makefiles will fail to work if
+run by anyone else.  It is much better to write explicit `include'
+directives in the makefiles.  *Note Including Other Makefiles: Include.
+
+
+File: make.info,  Node: Remaking Makefiles,  Next: Overriding Makefiles,  Prev: MAKEFILES Variable,  Up: Makefiles
+
+3.5 How Makefiles Are Remade
+============================
+
+Sometimes makefiles can be remade from other files, such as RCS or SCCS
+files.  If a makefile can be remade from other files, you probably want
+`make' to get an up-to-date version of the makefile to read in.
+
+   To this end, after reading in all makefiles, `make' will consider
+each as a goal target and attempt to update it.  If a makefile has a
+rule which says how to update it (found either in that very makefile or
+in another one) or if an implicit rule applies to it (*note Using
+Implicit Rules: Implicit Rules.), it will be updated if necessary.
+After all makefiles have been checked, if any have actually been
+changed, `make' starts with a clean slate and reads all the makefiles
+over again.  (It will also attempt to update each of them over again,
+but normally this will not change them again, since they are already up
+to date.)
+
+   If you know that one or more of your makefiles cannot be remade and
+you want to keep `make' from performing an implicit rule search on
+them, perhaps for efficiency reasons, you can use any normal method of
+preventing implicit rule lookup to do so.  For example, you can write
+an explicit rule with the makefile as the target, and an empty recipe
+(*note Using Empty Recipes: Empty Recipes.).
+
+   If the makefiles specify a double-colon rule to remake a file with a
+recipe but no prerequisites, that file will always be remade (*note
+Double-Colon::).  In the case of makefiles, a makefile that has a
+double-colon rule with a recipe but no prerequisites will be remade
+every time `make' is run, and then again after `make' starts over and
+reads the makefiles in again.  This would cause an infinite loop:
+`make' would constantly remake the makefile, and never do anything
+else.  So, to avoid this, `make' will *not* attempt to remake makefiles
+which are specified as targets of a double-colon rule with a recipe but
+no prerequisites.
+
+   If you do not specify any makefiles to be read with `-f' or `--file'
+options, `make' will try the default makefile names; *note What Name to
+Give Your Makefile: Makefile Names.  Unlike makefiles explicitly
+requested with `-f' or `--file' options, `make' is not certain that
+these makefiles should exist.  However, if a default makefile does not
+exist but can be created by running `make' rules, you probably want the
+rules to be run so that the makefile can be used.
+
+   Therefore, if none of the default makefiles exists, `make' will try
+to make each of them in the same order in which they are searched for
+(*note What Name to Give Your Makefile: Makefile Names.)  until it
+succeeds in making one, or it runs out of names to try.  Note that it
+is not an error if `make' cannot find or make any makefile; a makefile
+is not always necessary.
+
+   When you use the `-t' or `--touch' option (*note Instead of
+Executing Recipes: Instead of Execution.), you would not want to use an
+out-of-date makefile to decide which targets to touch.  So the `-t'
+option has no effect on updating makefiles; they are really updated
+even if `-t' is specified.  Likewise, `-q' (or `--question') and `-n'
+(or `--just-print') do not prevent updating of makefiles, because an
+out-of-date makefile would result in the wrong output for other targets.
+Thus, `make -f mfile -n foo' will update `mfile', read it in, and then
+print the recipe to update `foo' and its prerequisites without running
+it.  The recipe printed for `foo' will be the one specified in the
+updated contents of `mfile'.
+
+   However, on occasion you might actually wish to prevent updating of
+even the makefiles.  You can do this by specifying the makefiles as
+goals in the command line as well as specifying them as makefiles.
+When the makefile name is specified explicitly as a goal, the options
+`-t' and so on do apply to them.
+
+   Thus, `make -f mfile -n mfile foo' would read the makefile `mfile',
+print the recipe needed to update it without actually running it, and
+then print the recipe needed to update `foo' without running that.  The
+recipe for `foo' will be the one specified by the existing contents of
+`mfile'.

+
+3.6 Overriding Part of Another Makefile
+=======================================
+
+Sometimes it is useful to have a makefile that is mostly just like
+another makefile.  You can often use the `include' directive to include
+one in the other, and add more targets or variable definitions.
+However, it is illegal for two makefiles to give different recipes for
+the same target.  But there is another way.
+
+   In the containing makefile (the one that wants to include the other),
+you can use a match-anything pattern rule to say that to remake any
+target that cannot be made from the information in the containing
+makefile, `make' should look in another makefile.  *Note Pattern
+Rules::, for more information on pattern rules.
+
+   For example, if you have a makefile called `Makefile' that says how
+to make the target `foo' (and other targets), you can write a makefile
+called `GNUmakefile' that contains:
+
+     foo:
+             frobnicate > foo
+
+     %: force
+             @$(MAKE) -f Makefile $@
+     force: ;
+
+   If you say `make foo', `make' will find `GNUmakefile', read it, and
+see that to make `foo', it needs to run the recipe `frobnicate > foo'.
+If you say `make bar', `make' will find no way to make `bar' in
+`GNUmakefile', so it will use the recipe from the pattern rule: `make
+-f Makefile bar'.  If `Makefile' provides a rule for updating `bar',
+`make' will apply the rule.  And likewise for any other target that
+`GNUmakefile' does not say how to make.
+
+   The way this works is that the pattern rule has a pattern of just
+`%', so it matches any target whatever.  The rule specifies a
+prerequisite `force', to guarantee that the recipe will be run even if
+the target file already exists.  We give the `force' target an empty
+recipe to prevent `make' from searching for an implicit rule to build
+it--otherwise it would apply the same match-anything rule to `force'
+itself and create a prerequisite loop!

+
+3.7 How `make' Reads a Makefile
+===============================
+
+GNU `make' does its work in two distinct phases.  During the first
+phase it reads all the makefiles, included makefiles, etc. and
+internalizes all the variables and their values, implicit and explicit
+rules, and constructs a dependency graph of all the targets and their
+prerequisites.  During the second phase, `make' uses these internal
+structures to determine what targets will need to be rebuilt and to
+invoke the rules necessary to do so.
+
+   It's important to understand this two-phase approach because it has a
+direct impact on how variable and function expansion happens; this is
+often a source of some confusion when writing makefiles.  Here we will
+present a summary of the phases in which expansion happens for different
+constructs within the makefile.  We say that expansion is "immediate"
+if it happens during the first phase: in this case `make' will expand
+any variables or functions in that section of a construct as the
+makefile is parsed.  We say that expansion is "deferred" if expansion
+is not performed immediately.  Expansion of a deferred construct is not
+performed until either the construct appears later in an immediate
+context, or until the second phase.
+
+   You may not be familiar with some of these constructs yet.  You can
+reference this section as you become familiar with them, in later
+chapters.
+
+Variable Assignment
+-------------------
+
+Variable definitions are parsed as follows:
+
+     IMMEDIATE = DEFERRED
+     IMMEDIATE ?= DEFERRED
+     IMMEDIATE := IMMEDIATE
+     IMMEDIATE += DEFERRED or IMMEDIATE
+
+     define IMMEDIATE
+       DEFERRED
+     endef
+
+     define IMMEDIATE =
+       DEFERRED
+     endef
+
+     define IMMEDIATE ?=
+       DEFERRED
+     endef
+
+     define IMMEDIATE :=
+       IMMEDIATE
+     endef
+
+     define IMMEDIATE +=
+       DEFERRED or IMMEDIATE
+     endef
+
+   For the append operator, `+=', the right-hand side is considered
+immediate if the variable was previously set as a simple variable
+(`:='), and deferred otherwise.
+
+Conditional Directives
+----------------------
+
+Conditional directives are parsed immediately.  This means, for
+example, that automatic variables cannot be used in conditional
+directives, as automatic variables are not set until the recipe for
+that rule is invoked.  If you need to use automatic variables in a
+conditional directive you _must_ move the condition into the recipe and
+use shell conditional syntax instead.
+
+Rule Definition
+---------------
+
+A rule is always expanded the same way, regardless of the form:
+
+     IMMEDIATE : IMMEDIATE ; DEFERRED
+     	DEFERRED
+
+   That is, the target and prerequisite sections are expanded
+immediately, and the recipe used to construct the target is always
+deferred.  This general rule is true for explicit rules, pattern rules,
+suffix rules, static pattern rules, and simple prerequisite definitions.

+
+3.8 Secondary Expansion
+=======================
+
+In the previous section we learned that GNU `make' works in two
+distinct phases: a read-in phase and a target-update phase (*note How
+`make' Reads a Makefile: Reading Makefiles.).  GNU make also has the
+ability to enable a _second expansion_ of the prerequisites (only) for
+some or all targets defined in the makefile.  In order for this second
+expansion to occur, the special target `.SECONDEXPANSION' must be
+defined before the first prerequisite list that makes use of this
+feature.
+
+   If that special target is defined then in between the two phases
+mentioned above, right at the end of the read-in phase, all the
+prerequisites of the targets defined after the special target are
+expanded a _second time_.  In most circumstances this secondary
+expansion will have no effect, since all variable and function
+references will have been expanded during the initial parsing of the
+makefiles.  In order to take advantage of the secondary expansion phase
+of the parser, then, it's necessary to _escape_ the variable or
+function reference in the makefile.  In this case the first expansion
+merely un-escapes the reference but doesn't expand it, and expansion is
+left to the secondary expansion phase.  For example, consider this
+makefile:
+
+     .SECONDEXPANSION:
+     ONEVAR = onefile
+     TWOVAR = twofile
+     myfile: $(ONEVAR) $$(TWOVAR)
+
+   After the first expansion phase the prerequisites list of the
+`myfile' target will be `onefile' and `$(TWOVAR)'; the first
+(unescaped) variable reference to ONEVAR is expanded, while the second
+(escaped) variable reference is simply unescaped, without being
+recognized as a variable reference.  Now during the secondary expansion
+the first word is expanded again but since it contains no variable or
+function references it remains the static value `onefile', while the
+second word is now a normal reference to the variable TWOVAR, which is
+expanded to the value `twofile'.  The final result is that there are
+two prerequisites, `onefile' and `twofile'.
+
+   Obviously, this is not a very interesting case since the same result
+could more easily have been achieved simply by having both variables
+appear, unescaped, in the prerequisites list.  One difference becomes
+apparent if the variables are reset; consider this example:
+
+     .SECONDEXPANSION:
+     AVAR = top
+     onefile: $(AVAR)
+     twofile: $$(AVAR)
+     AVAR = bottom
+
+   Here the prerequisite of `onefile' will be expanded immediately, and
+resolve to the value `top', while the prerequisite of `twofile' will
+not be full expanded until the secondary expansion and yield a value of
+`bottom'.
+
+   This is marginally more exciting, but the true power of this feature
+only becomes apparent when you discover that secondary expansions
+always take place within the scope of the automatic variables for that
+target.  This means that you can use variables such as `$@', `$*', etc.
+during the second expansion and they will have their expected values,
+just as in the recipe.  All you have to do is defer the expansion by
+escaping the `$'.  Also, secondary expansion occurs for both explicit
+and implicit (pattern) rules.  Knowing this, the possible uses for this
+feature increase dramatically.  For example:
+
+     .SECONDEXPANSION:
+     main_OBJS := main.o try.o test.o
+     lib_OBJS := lib.o api.o
+
+     main lib: $$($$@_OBJS)
+
+   Here, after the initial expansion the prerequisites of both the
+`main' and `lib' targets will be `$($@_OBJS)'.  During the secondary
+expansion, the `$@' variable is set to the name of the target and so
+the expansion for the `main' target will yield `$(main_OBJS)', or
+`main.o try.o test.o', while the secondary expansion for the `lib'
+target will yield `$(lib_OBJS)', or `lib.o api.o'.
+
+   You can also mix in functions here, as long as they are properly
+escaped:
+
+     main_SRCS := main.c try.c test.c
+     lib_SRCS := lib.c api.c
+
+     .SECONDEXPANSION:
+     main lib: $$(patsubst %.c,%.o,$$($$@_SRCS))
+
+   This version allows users to specify source files rather than object
+files, but gives the same resulting prerequisites list as the previous
+example.
+
+   Evaluation of automatic variables during the secondary expansion
+phase, especially of the target name variable `$$@', behaves similarly
+to evaluation within recipes.  However, there are some subtle
+differences and "corner cases" which come into play for the different
+types of rule definitions that `make' understands.  The subtleties of
+using the different automatic variables are described below.
+
+Secondary Expansion of Explicit Rules
+-------------------------------------
+
+During the secondary expansion of explicit rules, `$$@' and `$$%'
+evaluate, respectively, to the file name of the target and, when the
+target is an archive member, the target member name.  The `$$<'
+variable evaluates to the first prerequisite in the first rule for this
+target.  `$$^' and `$$+' evaluate to the list of all prerequisites of
+rules _that have already appeared_ for the same target (`$$+' with
+repetitions and `$$^' without).  The following example will help
+illustrate these behaviors:
+
+     .SECONDEXPANSION:
+
+     foo: foo.1 bar.1 $$< $$^ $$+    # line #1
+
+     foo: foo.2 bar.2 $$< $$^ $$+    # line #2
+
+     foo: foo.3 bar.3 $$< $$^ $$+    # line #3
+
+   In the first prerequisite list, all three variables (`$$<', `$$^',
+and `$$+') expand to the empty string.  In the second, they will have
+values `foo.1', `foo.1 bar.1', and `foo.1 bar.1' respectively.  In the
+third they will have values `foo.1', `foo.1 bar.1 foo.2 bar.2', and
+`foo.1 bar.1 foo.2 bar.2 foo.1 foo.1 bar.1 foo.1 bar.1' respectively.
+
+   Rules undergo secondary expansion in makefile order, except that the
+rule with the recipe is always evaluated last.
+
+   The variables `$$?' and `$$*' are not available and expand to the
+empty string.
+
+Secondary Expansion of Static Pattern Rules
+-------------------------------------------
+
+Rules for secondary expansion of static pattern rules are identical to
+those for explicit rules, above, with one exception: for static pattern
+rules the `$$*' variable is set to the pattern stem.  As with explicit
+rules, `$$?' is not available and expands to the empty string.
+
+Secondary Expansion of Implicit Rules
+-------------------------------------
+
+As `make' searches for an implicit rule, it substitutes the stem and
+then performs secondary expansion for every rule with a matching target
+pattern.  The value of the automatic variables is derived in the same
+fashion as for static pattern rules.  As an example:
+
+     .SECONDEXPANSION:
+
+     foo: bar
+
+     foo foz: fo%: bo%
+
+     %oo: $$< $$^ $$+ $$*
+
+   When the implicit rule is tried for target `foo', `$$<' expands to
+`bar', `$$^' expands to `bar boo', `$$+' also expands to `bar boo', and
+`$$*' expands to `f'.
+
+   Note that the directory prefix (D), as described in *note Implicit
+Rule Search Algorithm: Implicit Rule Search, is appended (after
+expansion) to all the patterns in the prerequisites list.  As an
+example:
+
+     .SECONDEXPANSION:
+
+     /tmp/foo.o:
+
+     %.o: $$(addsuffix /%.c,foo bar) foo.h

+4 Writing Rules
+***************
+
+A "rule" appears in the makefile and says when and how to remake
+certain files, called the rule's "targets" (most often only one per
+rule).  It lists the other files that are the "prerequisites" of the
+target, and the "recipe" to use to create or update the target.
+
+   The order of rules is not significant, except for determining the
+"default goal": the target for `make' to consider, if you do not
+otherwise specify one.  The default goal is the target of the first
+rule in the first makefile.  If the first rule has multiple targets,
+only the first target is taken as the default.  There are two
+exceptions: a target starting with a period is not a default unless it
+contains one or more slashes, `/', as well; and, a target that defines
+a pattern rule has no effect on the default goal.  (*Note Defining and
+Redefining Pattern Rules: Pattern Rules.)
+
+   Therefore, we usually write the makefile so that the first rule is
+the one for compiling the entire program or all the programs described
+by the makefile (often with a target called `all').  *Note Arguments to
+Specify the Goals: Goals.

+4.1 Rule Example
+================
+
+Here is an example of a rule:
+
+     foo.o : foo.c defs.h       # module for twiddling the frobs
+             cc -c -g foo.c
+
+   Its target is `foo.o' and its prerequisites are `foo.c' and
+`defs.h'.  It has one command in the recipe: `cc -c -g foo.c'.  The
+recipe starts with a tab to identify it as a recipe.
+
+   This rule says two things:
+
+   * How to decide whether `foo.o' is out of date: it is out of date if
+     it does not exist, or if either `foo.c' or `defs.h' is more recent
+     than it.
+
+   * How to update the file `foo.o': by running `cc' as stated.  The
+     recipe does not explicitly mention `defs.h', but we presume that
+     `foo.c' includes it, and that that is why `defs.h' was added to
+     the prerequisites.

+
+4.2 Rule Syntax
+===============
+
+In general, a rule looks like this:
+
+     TARGETS : PREREQUISITES
+             RECIPE
+             ...
+
+or like this:
+
+     TARGETS : PREREQUISITES ; RECIPE
+             RECIPE
+             ...
+
+   The TARGETS are file names, separated by spaces.  Wildcard
+characters may be used (*note Using Wildcard Characters in File Names:
+Wildcards.) and a name of the form `A(M)' represents member M in
+archive file A (*note Archive Members as Targets: Archive Members.).
+Usually there is only one target per rule, but occasionally there is a
+reason to have more (*note Multiple Targets in a Rule: Multiple
+Targets.).
+
+   The RECIPE lines start with a tab character (or the first character
+in the value of the `.RECIPEPREFIX' variable; *note Special
+Variables::).  The first recipe line may appear on the line after the
+prerequisites, with a tab character, or may appear on the same line,
+with a semicolon.  Either way, the effect is the same.  There are other
+differences in the syntax of recipes.  *Note Writing Recipes in Rules:
+Recipes.
+
+   Because dollar signs are used to start `make' variable references,
+if you really want a dollar sign in a target or prerequisite you must
+write two of them, `$$' (*note How to Use Variables: Using Variables.).
+If you have enabled secondary expansion (*note Secondary Expansion::)
+and you want a literal dollar sign in the prerequisites list, you must
+actually write _four_ dollar signs (`$$$$').
+
+   You may split a long line by inserting a backslash followed by a
+newline, but this is not required, as `make' places no limit on the
+length of a line in a makefile.
+
+   A rule tells `make' two things: when the targets are out of date,
+and how to update them when necessary.
+
+   The criterion for being out of date is specified in terms of the
+PREREQUISITES, which consist of file names separated by spaces.
+(Wildcards and archive members (*note Archives::) are allowed here too.)
+A target is out of date if it does not exist or if it is older than any
+of the prerequisites (by comparison of last-modification times).  The
+idea is that the contents of the target file are computed based on
+information in the prerequisites, so if any of the prerequisites
+changes, the contents of the existing target file are no longer
+necessarily valid.
+
+   How to update is specified by a RECIPE.  This is one or more lines
+to be executed by the shell (normally `sh'), but with some extra
+features (*note Writing Recipes in Rules: Recipes.).
+
+

+
+4.3 Types of Prerequisites
+==========================
+
+There are actually two different types of prerequisites understood by
+GNU `make': normal prerequisites such as described in the previous
+section, and "order-only" prerequisites.  A normal prerequisite makes
+two statements: first, it imposes an order in which recipes will be
+invoked: the recipes for all prerequisites of a target will be
+completed before the recipe for the target is run.  Second, it imposes
+a dependency relationship: if any prerequisite is newer than the
+target, then the target is considered out-of-date and must be rebuilt.
+
+   Normally, this is exactly what you want: if a target's prerequisite
+is updated, then the target should also be updated.
+
+   Occasionally, however, you have a situation where you want to impose
+a specific ordering on the rules to be invoked _without_ forcing the
+target to be updated if one of those rules is executed.  In that case,
+you want to define "order-only" prerequisites.  Order-only
+prerequisites can be specified by placing a pipe symbol (`|') in the
+prerequisites list: any prerequisites to the left of the pipe symbol
+are normal; any prerequisites to the right are order-only:
+
+     TARGETS : NORMAL-PREREQUISITES | ORDER-ONLY-PREREQUISITES
+
+   The normal prerequisites section may of course be empty.  Also, you
+may still declare multiple lines of prerequisites for the same target:
+they are appended appropriately (normal prerequisites are appended to
+the list of normal prerequisites; order-only prerequisites are appended
+to the list of order-only prerequisites).  Note that if you declare the
+same file to be both a normal and an order-only prerequisite, the
+normal prerequisite takes precedence (since they have a strict superset
+of the behavior of an order-only prerequisite).
+
+   Consider an example where your targets are to be placed in a separate
+directory, and that directory might not exist before `make' is run.  In
+this situation, you want the directory to be created before any targets
+are placed into it but, because the timestamps on directories change
+whenever a file is added, removed, or renamed, we certainly don't want
+to rebuild all the targets whenever the directory's timestamp changes.
+One way to manage this is with order-only prerequisites: make the
+directory an order-only prerequisite on all the targets:
+
+     OBJDIR := objdir
+     OBJS := $(addprefix $(OBJDIR)/,foo.o bar.o baz.o)
+
+     $(OBJDIR)/%.o : %.c
+             $(COMPILE.c) $(OUTPUT_OPTION) $<
+
+     all: $(OBJS)
+
+     $(OBJS): | $(OBJDIR)
+
+     $(OBJDIR):
+             mkdir $(OBJDIR)
+
+   Now the rule to create the `objdir' directory will be run, if
+needed, before any `.o' is built, but no `.o' will be built because the
+`objdir' directory timestamp changed.

+
+4.4 Using Wildcard Characters in File Names
+===========================================
+
+A single file name can specify many files using "wildcard characters".
+The wildcard characters in `make' are `*', `?' and `[...]', the same as
+in the Bourne shell.  For example, `*.c' specifies a list of all the
+files (in the working directory) whose names end in `.c'.
+
+   The character `~' at the beginning of a file name also has special
+significance.  If alone, or followed by a slash, it represents your home
+directory.  For example `~/bin' expands to `/home/you/bin'.  If the `~'
+is followed by a word, the string represents the home directory of the
+user named by that word.  For example `~john/bin' expands to
+`/home/john/bin'.  On systems which don't have a home directory for
+each user (such as MS-DOS or MS-Windows), this functionality can be
+simulated by setting the environment variable HOME.
+
+   Wildcard expansion is performed by `make' automatically in targets
+and in prerequisites.  In recipes, the shell is responsible for
+wildcard expansion.  In other contexts, wildcard expansion happens only
+if you request it explicitly with the `wildcard' function.
+
+   The special significance of a wildcard character can be turned off by
+preceding it with a backslash.  Thus, `foo\*bar' would refer to a
+specific file whose name consists of `foo', an asterisk, and `bar'.

+* Wildcard Function::           How to cause wildcard expansion where

+
+
+File: make.info,  Node: Wildcard Examples,  Next: Wildcard Pitfall,  Prev: Wildcards,  Up: Wildcards
+
+4.4.1 Wildcard Examples
+-----------------------
+
+Wildcards can be used in the recipe of a rule, where they are expanded
+by the shell.  For example, here is a rule to delete all the object
+files:
+
+     clean:
+             rm -f *.o
+
+   Wildcards are also useful in the prerequisites of a rule.  With the
+following rule in the makefile, `make print' will print all the `.c'
+files that have changed since the last time you printed them:
+
+     print: *.c
+             lpr -p $?
+             touch print
+
+This rule uses `print' as an empty target file; see *note Empty Target
+Files to Record Events: Empty Targets.  (The automatic variable `$?' is
+used to print only those files that have changed; see *note Automatic
+Variables::.)
+
+   Wildcard expansion does not happen when you define a variable.
+Thus, if you write this:
+
+     objects = *.o
+
+then the value of the variable `objects' is the actual string `*.o'.
+However, if you use the value of `objects' in a target or prerequisite,
+wildcard expansion will take place there.  If you use the value of
+`objects' in a recipe, the shell may perform wildcard expansion when
+the recipe runs.  To set `objects' to the expansion, instead use:
+
+     objects := $(wildcard *.o)
+
+*Note Wildcard Function::.
+
+
+File: make.info,  Node: Wildcard Pitfall,  Next: Wildcard Function,  Prev: Wildcard Examples,  Up: Wildcards
+
+4.4.2 Pitfalls of Using Wildcards
+---------------------------------
+
+Now here is an example of a naive way of using wildcard expansion, that
+does not do what you would intend.  Suppose you would like to say that
+the executable file `foo' is made from all the object files in the
+directory, and you write this:
+
+     objects = *.o
+
+     foo : $(objects)
+             cc -o foo $(CFLAGS) $(objects)
+
+The value of `objects' is the actual string `*.o'.  Wildcard expansion
+happens in the rule for `foo', so that each _existing_ `.o' file
+becomes a prerequisite of `foo' and will be recompiled if necessary.
+
+   But what if you delete all the `.o' files?  When a wildcard matches
+no files, it is left as it is, so then `foo' will depend on the
+oddly-named file `*.o'.  Since no such file is likely to exist, `make'
+will give you an error saying it cannot figure out how to make `*.o'.
+This is not what you want!
+
+   Actually it is possible to obtain the desired result with wildcard
+expansion, but you need more sophisticated techniques, including the
+`wildcard' function and string substitution.  *Note The Function
+`wildcard': Wildcard Function.
+
+   Microsoft operating systems (MS-DOS and MS-Windows) use backslashes
+to separate directories in pathnames, like so:
+
+       c:\foo\bar\baz.c
+
+   This is equivalent to the Unix-style `c:/foo/bar/baz.c' (the `c:'
+part is the so-called drive letter).  When `make' runs on these
+systems, it supports backslashes as well as the Unix-style forward
+slashes in pathnames.  However, this support does _not_ include the
+wildcard expansion, where backslash is a quote character.  Therefore,
+you _must_ use Unix-style slashes in these cases.
+
+
+File: make.info,  Node: Wildcard Function,  Prev: Wildcard Pitfall,  Up: Wildcards
+
+4.4.3 The Function `wildcard'
+-----------------------------
+
+Wildcard expansion happens automatically in rules.  But wildcard
+expansion does not normally take place when a variable is set, or
+inside the arguments of a function.  If you want to do wildcard
+expansion in such places, you need to use the `wildcard' function, like
+this:
+
+     $(wildcard PATTERN...)
+
+This string, used anywhere in a makefile, is replaced by a
+space-separated list of names of existing files that match one of the
+given file name patterns.  If no existing file name matches a pattern,
+then that pattern is omitted from the output of the `wildcard'
+function.  Note that this is different from how unmatched wildcards
+behave in rules, where they are used verbatim rather than ignored
+(*note Wildcard Pitfall::).
+
+   One use of the `wildcard' function is to get a list of all the C
+source files in a directory, like this:
+
+     $(wildcard *.c)
+
+   We can change the list of C source files into a list of object files
+by replacing the `.c' suffix with `.o' in the result, like this:
+
+     $(patsubst %.c,%.o,$(wildcard *.c))
+
+(Here we have used another function, `patsubst'.  *Note Functions for
+String Substitution and Analysis: Text Functions.)
+
+   Thus, a makefile to compile all C source files in the directory and
+then link them together could be written as follows:
+
+     objects := $(patsubst %.c,%.o,$(wildcard *.c))
+
+     foo : $(objects)
+             cc -o foo $(objects)
+
+(This takes advantage of the implicit rule for compiling C programs, so
+there is no need to write explicit rules for compiling the files.
+*Note The Two Flavors of Variables: Flavors, for an explanation of
+`:=', which is a variant of `='.)

+4.5 Searching Directories for Prerequisites
+===========================================
+
+For large systems, it is often desirable to put sources in a separate
+directory from the binaries.  The "directory search" features of `make'
+facilitate this by searching several directories automatically to find
+a prerequisite.  When you redistribute the files among directories, you
+do not need to change the individual rules, just the search paths.

+
+4.5.1 `VPATH': Search Path for All Prerequisites
+------------------------------------------------
+
+The value of the `make' variable `VPATH' specifies a list of
+directories that `make' should search.  Most often, the directories are
+expected to contain prerequisite files that are not in the current
+directory; however, `make' uses `VPATH' as a search list for both
+prerequisites and targets of rules.
+
+   Thus, if a file that is listed as a target or prerequisite does not
+exist in the current directory, `make' searches the directories listed
+in `VPATH' for a file with that name.  If a file is found in one of
+them, that file may become the prerequisite (see below).  Rules may then
+specify the names of files in the prerequisite list as if they all
+existed in the current directory.  *Note Writing Recipes with Directory
+Search: Recipes/Search.
+
+   In the `VPATH' variable, directory names are separated by colons or
+blanks.  The order in which directories are listed is the order followed
+by `make' in its search.  (On MS-DOS and MS-Windows, semi-colons are
+used as separators of directory names in `VPATH', since the colon can
+be used in the pathname itself, after the drive letter.)
+
+   For example,
+
+     VPATH = src:../headers
+
+specifies a path containing two directories, `src' and `../headers',
+which `make' searches in that order.
+
+   With this value of `VPATH', the following rule,
+
+     foo.o : foo.c
+
+is interpreted as if it were written like this:
+
+     foo.o : src/foo.c
+
+assuming the file `foo.c' does not exist in the current directory but
+is found in the directory `src'.
+
+
+File: make.info,  Node: Selective Search,  Next: Search Algorithm,  Prev: General Search,  Up: Directory Search
+
+4.5.2 The `vpath' Directive
+---------------------------
+
+Similar to the `VPATH' variable, but more selective, is the `vpath'
+directive (note lower case), which allows you to specify a search path
+for a particular class of file names: those that match a particular
+pattern.  Thus you can supply certain search directories for one class
+of file names and other directories (or none) for other file names.
+
+   There are three forms of the `vpath' directive:
+
+`vpath PATTERN DIRECTORIES'
+     Specify the search path DIRECTORIES for file names that match
+     PATTERN.
+
+     The search path, DIRECTORIES, is a list of directories to be
+     searched, separated by colons (semi-colons on MS-DOS and
+     MS-Windows) or blanks, just like the search path used in the
+     `VPATH' variable.
+
+`vpath PATTERN'
+     Clear out the search path associated with PATTERN.
+
+`vpath'
+     Clear all search paths previously specified with `vpath'
+     directives.
+
+   A `vpath' pattern is a string containing a `%' character.  The
+string must match the file name of a prerequisite that is being searched
+for, the `%' character matching any sequence of zero or more characters
+(as in pattern rules; *note Defining and Redefining Pattern Rules:
+Pattern Rules.).  For example, `%.h' matches files that end in `.h'.
+(If there is no `%', the pattern must match the prerequisite exactly,
+which is not useful very often.)
+
+   `%' characters in a `vpath' directive's pattern can be quoted with
+preceding backslashes (`\').  Backslashes that would otherwise quote
+`%' characters can be quoted with more backslashes.  Backslashes that
+quote `%' characters or other backslashes are removed from the pattern
+before it is compared to file names.  Backslashes that are not in
+danger of quoting `%' characters go unmolested.
+
+   When a prerequisite fails to exist in the current directory, if the
+PATTERN in a `vpath' directive matches the name of the prerequisite
+file, then the DIRECTORIES in that directive are searched just like
+(and before) the directories in the `VPATH' variable.
+
+   For example,
+
+     vpath %.h ../headers
+
+tells `make' to look for any prerequisite whose name ends in `.h' in
+the directory `../headers' if the file is not found in the current
+directory.
+
+   If several `vpath' patterns match the prerequisite file's name, then
+`make' processes each matching `vpath' directive one by one, searching
+all the directories mentioned in each directive.  `make' handles
+multiple `vpath' directives in the order in which they appear in the
+makefile; multiple directives with the same pattern are independent of
+each other.
+
+   Thus,
+
+     vpath %.c foo
+     vpath %   blish
+     vpath %.c bar
+
+will look for a file ending in `.c' in `foo', then `blish', then `bar',
+while
+
+     vpath %.c foo:bar
+     vpath %   blish
+
+will look for a file ending in `.c' in `foo', then `bar', then `blish'.

+
+4.5.3 How Directory Searches are Performed
+------------------------------------------
+
+When a prerequisite is found through directory search, regardless of
+type (general or selective), the pathname located may not be the one
+that `make' actually provides you in the prerequisite list.  Sometimes
+the path discovered through directory search is thrown away.
+
+   The algorithm `make' uses to decide whether to keep or abandon a
+path found via directory search is as follows:
+
+  1. If a target file does not exist at the path specified in the
+     makefile, directory search is performed.
+
+  2. If the directory search is successful, that path is kept and this
+     file is tentatively stored as the target.
+
+  3. All prerequisites of this target are examined using this same
+     method.
+
+  4. After processing the prerequisites, the target may or may not need
+     to be rebuilt:
+
+       a. If the target does _not_ need to be rebuilt, the path to the
+          file found during directory search is used for any
+          prerequisite lists which contain this target.  In short, if
+          `make' doesn't need to rebuild the target then you use the
+          path found via directory search.
+
+       b. If the target _does_ need to be rebuilt (is out-of-date), the
+          pathname found during directory search is _thrown away_, and
+          the target is rebuilt using the file name specified in the
+          makefile.  In short, if `make' must rebuild, then the target
+          is rebuilt locally, not in the directory found via directory
+          search.
+
+   This algorithm may seem complex, but in practice it is quite often
+exactly what you want.
+
+   Other versions of `make' use a simpler algorithm: if the file does
+not exist, and it is found via directory search, then that pathname is
+always used whether or not the target needs to be built.  Thus, if the
+target is rebuilt it is created at the pathname discovered during
+directory search.
+
+   If, in fact, this is the behavior you want for some or all of your
+directories, you can use the `GPATH' variable to indicate this to
+`make'.
+
+   `GPATH' has the same syntax and format as `VPATH' (that is, a space-
+or colon-delimited list of pathnames).  If an out-of-date target is
+found by directory search in a directory that also appears in `GPATH',
+then that pathname is not thrown away.  The target is rebuilt using the
+expanded path.

+When a prerequisite is found in another directory through directory
+search, this cannot change the recipe of the rule; they will execute as
+written.  Therefore, you must write the recipe with care so that it
+will look for the prerequisite in the directory where `make' finds it.
+
+   This is done with the "automatic variables" such as `$^' (*note
+Automatic Variables::).  For instance, the value of `$^' is a list of
+all the prerequisites of the rule, including the names of the
+directories in which they were found, and the value of `$@' is the
+target.  Thus:
+
+     foo.o : foo.c
+             cc -c $(CFLAGS) $^ -o $@
+
+(The variable `CFLAGS' exists so you can specify flags for C
+compilation by implicit rules; we use it here for consistency so it will
+affect all C compilations uniformly; *note Variables Used by Implicit
+Rules: Implicit Variables.)
+
+   Often the prerequisites include header files as well, which you do
+not want to mention in the recipe.  The automatic variable `$<' is just
+the first prerequisite:
+
+     VPATH = src:../headers
+     foo.o : foo.c defs.h hack.h
+             cc -c $(CFLAGS) $< -o $@

+
+4.5.5 Directory Search and Implicit Rules
+-----------------------------------------
+
+The search through the directories specified in `VPATH' or with `vpath'
+also happens during consideration of implicit rules (*note Using
+Implicit Rules: Implicit Rules.).
+
+   For example, when a file `foo.o' has no explicit rule, `make'
+considers implicit rules, such as the built-in rule to compile `foo.c'
+if that file exists.  If such a file is lacking in the current
+directory, the appropriate directories are searched for it.  If `foo.c'
+exists (or is mentioned in the makefile) in any of the directories, the
+implicit rule for C compilation is applied.
+
+   The recipes of implicit rules normally use automatic variables as a
+matter of necessity; consequently they will use the file names found by
+directory search with no extra effort.
+

+File: make.info,  Node: Libraries/Search,  Prev: Implicit/Search,  Up: Directory Search
+
+4.5.6 Directory Search for Link Libraries
+-----------------------------------------
+
+Directory search applies in a special way to libraries used with the
+linker.  This special feature comes into play when you write a
+prerequisite whose name is of the form `-lNAME'.  (You can tell
+something strange is going on here because the prerequisite is normally
+the name of a file, and the _file name_ of a library generally looks
+like `libNAME.a', not like `-lNAME'.)
+
+   When a prerequisite's name has the form `-lNAME', `make' handles it
+specially by searching for the file `libNAME.so', and, if it is not
+found, for the file `libNAME.a' in the current directory, in
+directories specified by matching `vpath' search paths and the `VPATH'
+search path, and then in the directories `/lib', `/usr/lib', and
+`PREFIX/lib' (normally `/usr/local/lib', but MS-DOS/MS-Windows versions
+of `make' behave as if PREFIX is defined to be the root of the DJGPP
+installation tree).
+
+   For example, if there is a `/usr/lib/libcurses.a' library on your
+system (and no `/usr/lib/libcurses.so' file), then
+
+     foo : foo.c -lcurses
+             cc $^ -o $@
+
+would cause the command `cc foo.c /usr/lib/libcurses.a -o foo' to be
+executed when `foo' is older than `foo.c' or than
+`/usr/lib/libcurses.a'.
+
+   Although the default set of files to be searched for is `libNAME.so'
+and `libNAME.a', this is customizable via the `.LIBPATTERNS' variable.
+Each word in the value of this variable is a pattern string.  When a
+prerequisite like `-lNAME' is seen, `make' will replace the percent in
+each pattern in the list with NAME and perform the above directory
+searches using each library filename.
+
+   The default value for `.LIBPATTERNS' is `lib%.so lib%.a', which
+provides the default behavior described above.
+
+   You can turn off link library expansion completely by setting this
+variable to an empty value.

+
+4.6 Phony Targets
+=================
+
+A phony target is one that is not really the name of a file; rather it
+is just a name for a recipe to be executed when you make an explicit
+request.  There are two reasons to use a phony target: to avoid a
+conflict with a file of the same name, and to improve performance.
+
+   If you write a rule whose recipe will not create the target file, the
+recipe will be executed every time the target comes up for remaking.
+Here is an example:
+
+     clean:
+             rm *.o temp
+
+Because the `rm' command does not create a file named `clean', probably
+no such file will ever exist.  Therefore, the `rm' command will be
+executed every time you say `make clean'.  
+
+   The phony target will cease to work if anything ever does create a
+file named `clean' in this directory.  Since it has no prerequisites,
+the file `clean' would inevitably be considered up to date, and its
+recipe would not be executed.  To avoid this problem, you can explicitly
+declare the target to be phony, using the special target `.PHONY'
+(*note Special Built-in Target Names: Special Targets.) as follows:
+
+     .PHONY : clean
+
+Once this is done, `make clean' will run the recipe regardless of
+whether there is a file named `clean'.
+
+   Since it knows that phony targets do not name actual files that
+could be remade from other files, `make' skips the implicit rule search
+for phony targets (*note Implicit Rules::).  This is why declaring a
+target phony is good for performance, even if you are not worried about
+the actual file existing.
+
+   Thus, you first write the line that states that `clean' is a phony
+target, then you write the rule, like this:
+
+     .PHONY: clean
+     clean:
+             rm *.o temp
+
+   Another example of the usefulness of phony targets is in conjunction
+with recursive invocations of `make' (for more information, see *note
+Recursive Use of `make': Recursion.).  In this case the makefile will
+often contain a variable which lists a number of subdirectories to be
+built.  One way to handle this is with one rule whose recipe is a shell
+loop over the subdirectories, like this:
+
+     SUBDIRS = foo bar baz
+
+     subdirs:
+             for dir in $(SUBDIRS); do \
+               $(MAKE) -C $$dir; \
+             done
+
+   There are problems with this method, however.  First, any error
+detected in a submake is ignored by this rule, so it will continue to
+build the rest of the directories even when one fails.  This can be
+overcome by adding shell commands to note the error and exit, but then
+it will do so even if `make' is invoked with the `-k' option, which is
+unfortunate.  Second, and perhaps more importantly, you cannot take
+advantage of `make''s ability to build targets in parallel (*note
+Parallel Execution: Parallel.), since there is only one rule.
+
+   By declaring the subdirectories as phony targets (you must do this as
+the subdirectory obviously always exists; otherwise it won't be built)
+you can remove these problems:
+
+     SUBDIRS = foo bar baz
+
+     .PHONY: subdirs $(SUBDIRS)
+
+     subdirs: $(SUBDIRS)
+
+     $(SUBDIRS):
+             $(MAKE) -C $@
+
+     foo: baz
+
+   Here we've also declared that the `foo' subdirectory cannot be built
+until after the `baz' subdirectory is complete; this kind of
+relationship declaration is particularly important when attempting
+parallel builds.
+
+   A phony target should not be a prerequisite of a real target file;
+if it is, its recipe will be run every time `make' goes to update that
+file.  As long as a phony target is never a prerequisite of a real
+target, the phony target recipe will be executed only when the phony
+target is a specified goal (*note Arguments to Specify the Goals:
+Goals.).
+
+   Phony targets can have prerequisites.  When one directory contains
+multiple programs, it is most convenient to describe all of the
+programs in one makefile `./Makefile'.  Since the target remade by
+default will be the first one in the makefile, it is common to make
+this a phony target named `all' and give it, as prerequisites, all the
+individual programs.  For example:
+
+     all : prog1 prog2 prog3
+     .PHONY : all
+
+     prog1 : prog1.o utils.o
+             cc -o prog1 prog1.o utils.o
+
+     prog2 : prog2.o
+             cc -o prog2 prog2.o
+
+     prog3 : prog3.o sort.o utils.o
+             cc -o prog3 prog3.o sort.o utils.o
+
+Now you can say just `make' to remake all three programs, or specify as
+arguments the ones to remake (as in `make prog1 prog3').  Phoniness is
+not inherited: the prerequisites of a phony target are not themselves
+phony, unless explicitly declared to be so.
+
+   When one phony target is a prerequisite of another, it serves as a
+subroutine of the other.  For example, here `make cleanall' will delete
+the object files, the difference files, and the file `program':
+
+     .PHONY: cleanall cleanobj cleandiff
+
+     cleanall : cleanobj cleandiff
+             rm program
+
+     cleanobj :
+             rm *.o
+
+     cleandiff :
+             rm *.diff

+
+4.7 Rules without Recipes or Prerequisites
+==========================================
+
+If a rule has no prerequisites or recipe, and the target of the rule is
+a nonexistent file, then `make' imagines this target to have been
+updated whenever its rule is run.  This implies that all targets
+depending on this one will always have their recipe run.
+
+   An example will illustrate this:
+
+     clean: FORCE
+             rm $(objects)
+     FORCE:
+
+   Here the target `FORCE' satisfies the special conditions, so the
+target `clean' that depends on it is forced to run its recipe.  There
+is nothing special about the name `FORCE', but that is one name
+commonly used this way.
+
+   As you can see, using `FORCE' this way has the same results as using
+`.PHONY: clean'.
+
+   Using `.PHONY' is more explicit and more efficient.  However, other
+versions of `make' do not support `.PHONY'; thus `FORCE' appears in
+many makefiles.  *Note Phony Targets::.
+

+File: make.info,  Node: Empty Targets,  Next: Special Targets,  Prev: Force Targets,  Up: Rules
+
+4.8 Empty Target Files to Record Events
+=======================================
+
+The "empty target" is a variant of the phony target; it is used to hold
+recipes for an action that you request explicitly from time to time.
+Unlike a phony target, this target file can really exist; but the file's
+contents do not matter, and usually are empty.
+
+   The purpose of the empty target file is to record, with its
+last-modification time, when the rule's recipe was last executed.  It
+does so because one of the commands in the recipe is a `touch' command
+to update the target file.
+
+   The empty target file should have some prerequisites (otherwise it
+doesn't make sense).  When you ask to remake the empty target, the
+recipe is executed if any prerequisite is more recent than the target;
+in other words, if a prerequisite has changed since the last time you
+remade the target.  Here is an example:
+
+     print: foo.c bar.c
+             lpr -p $?
+             touch print
+   
+With this rule, `make print' will execute the `lpr' command if either
+source file has changed since the last `make print'.  The automatic
+variable `$?' is used to print only those files that have changed
+(*note Automatic Variables::).

+
+4.9 Special Built-in Target Names
+=================================
+
+Certain names have special meanings if they appear as targets.
+
+`.PHONY'
+     The prerequisites of the special target `.PHONY' are considered to
+     be phony targets.  When it is time to consider such a target,
+     `make' will run its recipe unconditionally, regardless of whether
+     a file with that name exists or what its last-modification time
+     is.  *Note Phony Targets: Phony Targets.
+
+`.SUFFIXES'
+     The prerequisites of the special target `.SUFFIXES' are the list
+     of suffixes to be used in checking for suffix rules.  *Note
+     Old-Fashioned Suffix Rules: Suffix Rules.
+
+`.DEFAULT'
+     The recipe specified for `.DEFAULT' is used for any target for
+     which no rules are found (either explicit rules or implicit rules).
+     *Note Last Resort::.  If a `.DEFAULT' recipe is specified, every
+     file mentioned as a prerequisite, but not as a target in a rule,
+     will have that recipe executed on its behalf.  *Note Implicit Rule
+     Search Algorithm: Implicit Rule Search.
+
+`.PRECIOUS'
+     The targets which `.PRECIOUS' depends on are given the following
+     special treatment: if `make' is killed or interrupted during the
+     execution of their recipes, the target is not deleted.  *Note
+     Interrupting or Killing `make': Interrupts.  Also, if the target
+     is an intermediate file, it will not be deleted after it is no
+     longer needed, as is normally done.  *Note Chains of Implicit
+     Rules: Chained Rules.  In this latter respect it overlaps with the
+     `.SECONDARY' special target.
+
+     You can also list the target pattern of an implicit rule (such as
+     `%.o') as a prerequisite file of the special target `.PRECIOUS' to
+     preserve intermediate files created by rules whose target patterns
+     match that file's name.
+
+`.INTERMEDIATE'
+     The targets which `.INTERMEDIATE' depends on are treated as
+     intermediate files.  *Note Chains of Implicit Rules: Chained Rules.
+     `.INTERMEDIATE' with no prerequisites has no effect.
+
+`.SECONDARY'
+     The targets which `.SECONDARY' depends on are treated as
+     intermediate files, except that they are never automatically
+     deleted.  *Note Chains of Implicit Rules: Chained Rules.
+
+     `.SECONDARY' with no prerequisites causes all targets to be treated
+     as secondary (i.e., no target is removed because it is considered
+     intermediate).
+
+`.SECONDEXPANSION'
+     If `.SECONDEXPANSION' is mentioned as a target anywhere in the
+     makefile, then all prerequisite lists defined _after_ it appears
+     will be expanded a second time after all makefiles have been read
+     in.  *Note Secondary Expansion: Secondary Expansion.
+
+`.DELETE_ON_ERROR'
+     If `.DELETE_ON_ERROR' is mentioned as a target anywhere in the
+     makefile, then `make' will delete the target of a rule if it has
+     changed and its recipe exits with a nonzero exit status, just as it
+     does when it receives a signal.  *Note Errors in Recipes: Errors.
+
+`.IGNORE'
+     If you specify prerequisites for `.IGNORE', then `make' will
+     ignore errors in execution of the recipe for those particular
+     files.  The recipe for `.IGNORE' (if any) is ignored.
+
+     If mentioned as a target with no prerequisites, `.IGNORE' says to
+     ignore errors in execution of recipes for all files.  This usage of
+     `.IGNORE' is supported only for historical compatibility.  Since
+     this affects every recipe in the makefile, it is not very useful;
+     we recommend you use the more selective ways to ignore errors in
+     specific recipes.  *Note Errors in Recipes: Errors.
+
+`.LOW_RESOLUTION_TIME'
+     If you specify prerequisites for `.LOW_RESOLUTION_TIME', `make'
+     assumes that these files are created by commands that generate low
+     resolution time stamps.  The recipe for the `.LOW_RESOLUTION_TIME'
+     target are ignored.
+
+     The high resolution file time stamps of many modern file systems
+     lessen the chance of `make' incorrectly concluding that a file is
+     up to date.  Unfortunately, some hosts do not provide a way to set
+     a high resolution file time stamp, so commands like `cp -p' that
+     explicitly set a file's time stamp must discard its subsecond part.
+     If a file is created by such a command, you should list it as a
+     prerequisite of `.LOW_RESOLUTION_TIME' so that `make' does not
+     mistakenly conclude that the file is out of date.  For example:
+
+          .LOW_RESOLUTION_TIME: dst
+          dst: src
+                  cp -p src dst
+
+     Since `cp -p' discards the subsecond part of `src''s time stamp,
+     `dst' is typically slightly older than `src' even when it is up to
+     date.  The `.LOW_RESOLUTION_TIME' line causes `make' to consider
+     `dst' to be up to date if its time stamp is at the start of the
+     same second that `src''s time stamp is in.
+
+     Due to a limitation of the archive format, archive member time
+     stamps are always low resolution.  You need not list archive
+     members as prerequisites of `.LOW_RESOLUTION_TIME', as `make' does
+     this automatically.
+
+`.SILENT'
+     If you specify prerequisites for `.SILENT', then `make' will not
+     print the recipe used to remake those particular files before
+     executing them.  The recipe for `.SILENT' is ignored.
+
+     If mentioned as a target with no prerequisites, `.SILENT' says not
+     to print any recipes before executing them.  This usage of
+     `.SILENT' is supported only for historical compatibility.  We
+     recommend you use the more selective ways to silence specific
+     recipes.  *Note Recipe Echoing: Echoing.  If you want to silence
+     all recipes for a particular run of `make', use the `-s' or
+     `--silent' option (*note Options Summary::).
+
+`.EXPORT_ALL_VARIABLES'
+     Simply by being mentioned as a target, this tells `make' to export
+     all variables to child processes by default.  *Note Communicating
+     Variables to a Sub-`make': Variables/Recursion.
+
+`.NOTPARALLEL'
+     If `.NOTPARALLEL' is mentioned as a target, then this invocation
+     of `make' will be run serially, even if the `-j' option is given.
+     Any recursively invoked `make' command will still run recipes in
+     parallel (unless its makefile also contains this target).  Any
+     prerequisites on this target are ignored.
+
+`.ONESHELL'
+     If `.ONESHELL' is mentioned as a target, then when a target is
+     built all lines of the recipe will be given to a single invocation
+     of the shell rather than each line being invoked separately (*note
+     Recipe Execution: Execution.).
+
+`.POSIX'
+     If `.POSIX' is mentioned as a target, then the makefile will be
+     parsed and run in POSIX-conforming mode.  This does _not_ mean
+     that only POSIX-conforming makefiles will be accepted: all advanced
+     GNU `make' features are still available.  Rather, this target
+     causes `make' to behave as required by POSIX in those areas where
+     `make''s default behavior differs.
+
+     In particular, if this target is mentioned then recipes will be
+     invoked as if the shell had been passed the `-e' flag: the first
+     failing command in a recipe will cause the recipe to fail
+     immediately.
+
+   Any defined implicit rule suffix also counts as a special target if
+it appears as a target, and so does the concatenation of two suffixes,
+such as `.c.o'.  These targets are suffix rules, an obsolete way of
+defining implicit rules (but a way still widely used).  In principle,
+any target name could be special in this way if you break it in two and
+add both pieces to the suffix list.  In practice, suffixes normally
+begin with `.', so these special target names also begin with `.'.
+*Note Old-Fashioned Suffix Rules: Suffix Rules.

+
+4.10 Multiple Targets in a Rule
+===============================
+
+A rule with multiple targets is equivalent to writing many rules, each
+with one target, and all identical aside from that.  The same recipe
+applies to all the targets, but its effect may vary because you can
+substitute the actual target name into the recipe using `$@'.  The rule
+contributes the same prerequisites to all the targets also.
+
+   This is useful in two cases.
+
+   * You want just prerequisites, no recipe.  For example:
+
+          kbd.o command.o files.o: command.h
+
+     gives an additional prerequisite to each of the three object files
+     mentioned.
+
+   * Similar recipes work for all the targets.  The recipes do not need
+     to be absolutely identical, since the automatic variable `$@' can
+     be used to substitute the particular target to be remade into the
+     commands (*note Automatic Variables::).  For example:
+
+          bigoutput littleoutput : text.g
+                  generate text.g -$(subst output,,$@) > $@
+     
+     is equivalent to
+
+          bigoutput : text.g
+                  generate text.g -big > bigoutput
+          littleoutput : text.g
+                  generate text.g -little > littleoutput
+
+     Here we assume the hypothetical program `generate' makes two types
+     of output, one if given `-big' and one if given `-little'.  *Note
+     Functions for String Substitution and Analysis: Text Functions,
+     for an explanation of the `subst' function.
+
+   Suppose you would like to vary the prerequisites according to the
+target, much as the variable `$@' allows you to vary the recipe.  You
+cannot do this with multiple targets in an ordinary rule, but you can
+do it with a "static pattern rule".  *Note Static Pattern Rules: Static
+Pattern.

+File: make.info,  Node: Multiple Rules,  Next: Static Pattern,  Prev: Multiple Targets,  Up: Rules
+
+4.11 Multiple Rules for One Target
+==================================
+
+One file can be the target of several rules.  All the prerequisites
+mentioned in all the rules are merged into one list of prerequisites for
+the target.  If the target is older than any prerequisite from any rule,
+the recipe is executed.
+
+   There can only be one recipe to be executed for a file.  If more than
+one rule gives a recipe for the same file, `make' uses the last one
+given and prints an error message.  (As a special case, if the file's
+name begins with a dot, no error message is printed.  This odd behavior
+is only for compatibility with other implementations of `make'... you
+should avoid using it).  Occasionally it is useful to have the same
+target invoke multiple recipes which are defined in different parts of
+your makefile; you can use "double-colon rules" (*note Double-Colon::)
+for this.
+
+   An extra rule with just prerequisites can be used to give a few extra
+prerequisites to many files at once.  For example, makefiles often have
+a variable, such as `objects', containing a list of all the compiler
+output files in the system being made.  An easy way to say that all of
+them must be recompiled if `config.h' changes is to write the following:
+
+     objects = foo.o bar.o
+     foo.o : defs.h
+     bar.o : defs.h test.h
+     $(objects) : config.h
+
+   This could be inserted or taken out without changing the rules that
+really specify how to make the object files, making it a convenient
+form to use if you wish to add the additional prerequisite
+intermittently.
+
+   Another wrinkle is that the additional prerequisites could be
+specified with a variable that you set with a command line argument to
+`make' (*note Overriding Variables: Overriding.).  For example,
+
+     extradeps=
+     $(objects) : $(extradeps)
+
+means that the command `make extradeps=foo.h' will consider `foo.h' as
+a prerequisite of each object file, but plain `make' will not.
+
+   If none of the explicit rules for a target has a recipe, then `make'
+searches for an applicable implicit rule to find one *note Using
+Implicit Rules: Implicit Rules.).

+4.12.1 Syntax of Static Pattern Rules
+-------------------------------------
+
+Here is the syntax of a static pattern rule:
+
+     TARGETS ...: TARGET-PATTERN: PREREQ-PATTERNS ...
+             RECIPE
+             ...
+
+The TARGETS list specifies the targets that the rule applies to.  The
+targets can contain wildcard characters, just like the targets of
+ordinary rules (*note Using Wildcard Characters in File Names:
+Wildcards.).
+
+   The TARGET-PATTERN and PREREQ-PATTERNS say how to compute the
+prerequisites of each target.  Each target is matched against the
+TARGET-PATTERN to extract a part of the target name, called the "stem".
+This stem is substituted into each of the PREREQ-PATTERNS to make the
+prerequisite names (one from each PREREQ-PATTERN).
+
+   Each pattern normally contains the character `%' just once.  When the
+TARGET-PATTERN matches a target, the `%' can match any part of the
+target name; this part is called the "stem".  The rest of the pattern
+must match exactly.  For example, the target `foo.o' matches the
+pattern `%.o', with `foo' as the stem.  The targets `foo.c' and
+`foo.out' do not match that pattern.
+
+   The prerequisite names for each target are made by substituting the
+stem for the `%' in each prerequisite pattern.  For example, if one
+prerequisite pattern is `%.c', then substitution of the stem `foo'
+gives the prerequisite name `foo.c'.  It is legitimate to write a
+prerequisite pattern that does not contain `%'; then this prerequisite
+is the same for all targets.
+
+   `%' characters in pattern rules can be quoted with preceding
+backslashes (`\').  Backslashes that would otherwise quote `%'
+characters can be quoted with more backslashes.  Backslashes that quote
+`%' characters or other backslashes are removed from the pattern before
+it is compared to file names or has a stem substituted into it.
+Backslashes that are not in danger of quoting `%' characters go
+unmolested.  For example, the pattern `the\%weird\\%pattern\\' has
+`the%weird\' preceding the operative `%' character, and `pattern\\'
+following it.  The final two backslashes are left alone because they
+cannot affect any `%' character.
+
+   Here is an example, which compiles each of `foo.o' and `bar.o' from
+the corresponding `.c' file:
+
+     objects = foo.o bar.o
+
+     all: $(objects)
+
+     $(objects): %.o: %.c
+             $(CC) -c $(CFLAGS) $< -o $@
+
+Here `$<' is the automatic variable that holds the name of the
+prerequisite and `$@' is the automatic variable that holds the name of
+the target; see *note Automatic Variables::.
+
+   Each target specified must match the target pattern; a warning is
+issued for each target that does not.  If you have a list of files,
+only some of which will match the pattern, you can use the `filter'
+function to remove nonmatching file names (*note Functions for String
+Substitution and Analysis: Text Functions.):
+
+     files = foo.elc bar.o lose.o
+
+     $(filter %.o,$(files)): %.o: %.c
+             $(CC) -c $(CFLAGS) $< -o $@
+     $(filter %.elc,$(files)): %.elc: %.el
+             emacs -f batch-byte-compile $<
+
+In this example the result of `$(filter %.o,$(files))' is `bar.o
+lose.o', and the first static pattern rule causes each of these object
+files to be updated by compiling the corresponding C source file.  The
+result of `$(filter %.elc,$(files))' is `foo.elc', so that file is made
+from `foo.el'.
+
+   Another example shows how to use `$*' in static pattern rules: 
+
+     bigoutput littleoutput : %output : text.g
+             generate text.g -$* > $@
+
+When the `generate' command is run, `$*' will expand to the stem,
+either `big' or `little'.

+4.12.2 Static Pattern Rules versus Implicit Rules
+-------------------------------------------------
+
+A static pattern rule has much in common with an implicit rule defined
+as a pattern rule (*note Defining and Redefining Pattern Rules: Pattern
+Rules.).  Both have a pattern for the target and patterns for
+constructing the names of prerequisites.  The difference is in how
+`make' decides _when_ the rule applies.
+
+   An implicit rule _can_ apply to any target that matches its pattern,
+but it _does_ apply only when the target has no recipe otherwise
+specified, and only when the prerequisites can be found.  If more than
+one implicit rule appears applicable, only one applies; the choice
+depends on the order of rules.
+
+   By contrast, a static pattern rule applies to the precise list of
+targets that you specify in the rule.  It cannot apply to any other
+target and it invariably does apply to each of the targets specified.
+If two conflicting rules apply, and both have recipes, that's an error.
+
+   The static pattern rule can be better than an implicit rule for these
+reasons:
+
+   * You may wish to override the usual implicit rule for a few files
+     whose names cannot be categorized syntactically but can be given
+     in an explicit list.
+
+   * If you cannot be sure of the precise contents of the directories
+     you are using, you may not be sure which other irrelevant files
+     might lead `make' to use the wrong implicit rule.  The choice
+     might depend on the order in which the implicit rule search is
+     done.  With static pattern rules, there is no uncertainty: each
+     rule applies to precisely the targets specified.

+
+4.13 Double-Colon Rules
+=======================
+
+"Double-colon" rules are explicit rules written with `::' instead of
+`:' after the target names.  They are handled differently from ordinary
+rules when the same target appears in more than one rule.  Pattern
+rules with double-colons have an entirely different meaning (*note
+Match-Anything Rules::).
+
+   When a target appears in multiple rules, all the rules must be the
+same type: all ordinary, or all double-colon.  If they are
+double-colon, each of them is independent of the others.  Each
+double-colon rule's recipe is executed if the target is older than any
+prerequisites of that rule.  If there are no prerequisites for that
+rule, its recipe is always executed (even if the target already
+exists).  This can result in executing none, any, or all of the
+double-colon rules.
+
+   Double-colon rules with the same target are in fact completely
+separate from one another.  Each double-colon rule is processed
+individually, just as rules with different targets are processed.
+
+   The double-colon rules for a target are executed in the order they
+appear in the makefile.  However, the cases where double-colon rules
+really make sense are those where the order of executing the recipes
+would not matter.
+
+   Double-colon rules are somewhat obscure and not often very useful;
+they provide a mechanism for cases in which the method used to update a
+target differs depending on which prerequisite files caused the update,
+and such cases are rare.
+
+   Each double-colon rule should specify a recipe; if it does not, an
+implicit rule will be used if one applies.  *Note Using Implicit Rules:
+Implicit Rules.

+
+4.14 Generating Prerequisites Automatically
+===========================================
+
+In the makefile for a program, many of the rules you need to write often
+say only that some object file depends on some header file.  For
+example, if `main.c' uses `defs.h' via an `#include', you would write:
+
+     main.o: defs.h
+
+You need this rule so that `make' knows that it must remake `main.o'
+whenever `defs.h' changes.  You can see that for a large program you
+would have to write dozens of such rules in your makefile.  And, you
+must always be very careful to update the makefile every time you add
+or remove an `#include'.  
+
+   To avoid this hassle, most modern C compilers can write these rules
+for you, by looking at the `#include' lines in the source files.
+Usually this is done with the `-M' option to the compiler.  For
+example, the command:
+
+     cc -M main.c
+
+generates the output:
+
+     main.o : main.c defs.h
+
+Thus you no longer have to write all those rules yourself.  The
+compiler will do it for you.
+
+   Note that such a prerequisite constitutes mentioning `main.o' in a
+makefile, so it can never be considered an intermediate file by implicit
+rule search.  This means that `make' won't ever remove the file after
+using it; *note Chains of Implicit Rules: Chained Rules.
+
+   With old `make' programs, it was traditional practice to use this
+compiler feature to generate prerequisites on demand with a command like
+`make depend'.  That command would create a file `depend' containing
+all the automatically-generated prerequisites; then the makefile could
+use `include' to read them in (*note Include::).
+
+   In GNU `make', the feature of remaking makefiles makes this practice
+obsolete--you need never tell `make' explicitly to regenerate the
+prerequisites, because it always regenerates any makefile that is out
+of date.  *Note Remaking Makefiles::.
+
+   The practice we recommend for automatic prerequisite generation is
+to have one makefile corresponding to each source file.  For each
+source file `NAME.c' there is a makefile `NAME.d' which lists what
+files the object file `NAME.o' depends on.  That way only the source
+files that have changed need to be rescanned to produce the new
+prerequisites.
+
+   Here is the pattern rule to generate a file of prerequisites (i.e.,
+a makefile) called `NAME.d' from a C source file called `NAME.c':
+
+     %.d: %.c
+             @set -e; rm -f $@; \
+              $(CC) -M $(CPPFLAGS) $< > $@.$$$$; \
+              sed 's,\($*\)\.o[ :]*,\1.o $@ : ,g' < $@.$$$$ > $@; \
+              rm -f $@.$$$$
+
+*Note Pattern Rules::, for information on defining pattern rules.  The
+`-e' flag to the shell causes it to exit immediately if the `$(CC)'
+command (or any other command) fails (exits with a nonzero status).  
+
+   With the GNU C compiler, you may wish to use the `-MM' flag instead
+of `-M'.  This omits prerequisites on system header files.  *Note
+Options Controlling the Preprocessor: (gcc.info)Preprocessor Options,
+for details.
+
+   The purpose of the `sed' command is to translate (for example):
+
+     main.o : main.c defs.h
+
+into:
+
+     main.o main.d : main.c defs.h
+
+This makes each `.d' file depend on all the source and header files
+that the corresponding `.o' file depends on.  `make' then knows it must
+regenerate the prerequisites whenever any of the source or header files
+changes.
+
+   Once you've defined the rule to remake the `.d' files, you then use
+the `include' directive to read them all in.  *Note Include::.  For
+example:
+
+     sources = foo.c bar.c
+
+     include $(sources:.c=.d)
+
+(This example uses a substitution variable reference to translate the
+list of source files `foo.c bar.c' into a list of prerequisite
+makefiles, `foo.d bar.d'.  *Note Substitution Refs::, for full
+information on substitution references.)  Since the `.d' files are
+makefiles like any others, `make' will remake them as necessary with no
+further work from you.  *Note Remaking Makefiles::.
+
+   Note that the `.d' files contain target definitions; you should be
+sure to place the `include' directive _after_ the first, default goal
+in your makefiles or run the risk of having a random object file become
+the default goal.  *Note How Make Works::.

+
+5.1 Recipe Syntax
+=================
+
+Makefiles have the unusual property that there are really two distinct
+syntaxes in one file.  Most of the makefile uses `make' syntax (*note
+Writing Makefiles: Makefiles.).  However, recipes are meant to be
+interpreted by the shell and so they are written using shell syntax.
+The `make' program does not try to understand shell syntax: it performs
+only a very few specific translations on the content of the recipe
+before handing it to the shell.
+
+   Each line in the recipe must start with a tab (or the first character
+in the value of the `.RECIPEPREFIX' variable; *note Special
+Variables::), except that the first recipe line may be attached to the
+target-and-prerequisites line with a semicolon in between.  _Any_ line
+in the makefile that begins with a tab and appears in a "rule context"
+(that is, after a rule has been started until another rule or variable
+definition) will be considered part of a recipe for that rule.  Blank
+lines and lines of just comments may appear among the recipe lines;
+they are ignored.
+
+   Some consequences of these rules include:
+
+   * A blank line that begins with a tab is not blank: it's an empty
+     recipe (*note Empty Recipes::).
+
+   * A comment in a recipe is not a `make' comment; it will be passed
+     to the shell as-is.  Whether the shell treats it as a comment or
+     not depends on your shell.
+
+   * A variable definition in a "rule context" which is indented by a
+     tab as the first character on the line, will be considered part of
+     a recipe, not a `make' variable definition, and passed to the
+     shell.
+
+   * A conditional expression (`ifdef', `ifeq', etc. *note Syntax of
+     Conditionals: Conditional Syntax.) in a "rule context" which is
+     indented by a tab as the first character on the line, will be
+     considered part of a recipe and be passed to the shell.

+
+5.1.1 Splitting Recipe Lines
+----------------------------
+
+One of the few ways in which `make' does interpret recipes is checking
+for a backslash just before the newline.  As in normal makefile syntax,
+a single logical recipe line can be split into multiple physical lines
+in the makefile by placing a backslash before each newline.  A sequence
+of lines like this is considered a single recipe line, and one instance
+of the shell will be invoked to run it.
+
+   However, in contrast to how they are treated in other places in a
+makefile, backslash-newline pairs are _not_ removed from the recipe.
+Both the backslash and the newline characters are preserved and passed
+to the shell.  How the backslash-newline is interpreted depends on your
+shell.  If the first character of the next line after the
+backslash-newline is the recipe prefix character (a tab by default;
+*note Special Variables::), then that character (and only that
+character) is removed.  Whitespace is never added to the recipe.
+
+   For example, the recipe for the all target in this makefile:
+
+     all :
+             @echo no\
+     space
+             @echo no\
+             space
+             @echo one \
+             space
+             @echo one\
+              space
+
+consists of four separate shell commands where the output is:
+
+     nospace
+     nospace
+     one space
+     one space
+
+   As a more complex example, this makefile:
+
+     all : ; @echo 'hello \
+             world' ; echo "hello \
+         world"
+
+will invoke one shell with a command of:
+
+     echo 'hello \
+     world' ; echo "hello \
+         world"
+
+which, according to shell quoting rules, will yield the following
+output:
+
+     hello \
+     world
+     hello     world
+
+Notice how the backslash/newline pair was removed inside the string
+quoted with double quotes (`"..."'), but not from the string quoted
+with single quotes (`'...'').  This is the way the default shell
+(`/bin/sh') handles backslash/newline pairs.  If you specify a
+different shell in your makefiles it may treat them differently.
+
+   Sometimes you want to split a long line inside of single quotes, but
+you don't want the backslash-newline to appear in the quoted content.
+This is often the case when passing scripts to languages such as Perl,
+where extraneous backslashes inside the script can change its meaning
+or even be a syntax error.  One simple way of handling this is to place
+the quoted string, or even the entire command, into a `make' variable
+then use the variable in the recipe.  In this situation the newline
+quoting rules for makefiles will be used, and the backslash-newline
+will be removed.  If we rewrite our example above using this method:
+
+     HELLO = 'hello \
+     world'
+
+     all : ; @echo $(HELLO)
+
+we will get output like this:
+
+     hello world
+
+   If you like, you can also use target-specific variables (*note
+Target-specific Variable Values: Target-specific.) to obtain a tighter
+correspondence between the variable and the recipe that uses it.
+
+
+File: make.info,  Node: Variables in Recipes,  Prev: Splitting Lines,  Up: Recipe Syntax
+
+5.1.2 Using Variables in Recipes
+--------------------------------
+
+The other way in which `make' processes recipes is by expanding any
+variable references in them (*note Basics of Variable References:
+Reference.).  This occurs after make has finished reading all the
+makefiles and the target is determined to be out of date; so, the
+recipes for targets which are not rebuilt are never expanded.
+
+   Variable and function references in recipes have identical syntax and
+semantics to references elsewhere in the makefile.  They also have the
+same quoting rules: if you want a dollar sign to appear in your recipe,
+you must double it (`$$').  For shells like the default shell, that use
+dollar signs to introduce variables, it's important to keep clear in
+your mind whether the variable you want to reference is a `make'
+variable (use a single dollar sign) or a shell variable (use two dollar
+signs).  For example:
+
+     LIST = one two three
+     all:
+             for i in $(LIST); do \
+                 echo $$i; \
+             done
+
+results in the following command being passed to the shell:
+
+     for i in one two three; do \
+         echo $i; \
+     done
+
+which generates the expected result:
+
+     one
+     two
+     three

+
+5.2 Recipe Echoing
+==================
+
+Normally `make' prints each line of the recipe before it is executed.
+We call this "echoing" because it gives the appearance that you are
+typing the lines yourself.
+
+   When a line starts with `@', the echoing of that line is suppressed.
+The `@' is discarded before the line is passed to the shell.  Typically
+you would use this for a command whose only effect is to print
+something, such as an `echo' command to indicate progress through the
+makefile:
+
+     @echo About to make distribution files
+
+   When `make' is given the flag `-n' or `--just-print' it only echoes
+most recipes, without executing them.  *Note Summary of Options:
+Options Summary.  In this case even the recipe lines starting with `@'
+are printed.  This flag is useful for finding out which recipes `make'
+thinks are necessary without actually doing them.
+
+   The `-s' or `--silent' flag to `make' prevents all echoing, as if
+all recipes started with `@'.  A rule in the makefile for the special
+target `.SILENT' without prerequisites has the same effect (*note
+Special Built-in Target Names: Special Targets.).  `.SILENT' is
+essentially obsolete since `@' is more flexible.
+
+
+File: make.info,  Node: Execution,  Next: Parallel,  Prev: Echoing,  Up: Recipes
+
+5.3 Recipe Execution
+====================
+
+When it is time to execute recipes to update a target, they are
+executed by invoking a new subshell for each line of the recipe, unless
+the `.ONESHELL' special target is in effect (*note Using One Shell: One
+Shell.)  (In practice, `make' may take shortcuts that do not affect the
+results.)
+
+   *Please note:* this implies that setting shell variables and
+invoking shell commands such as `cd' that set a context local to each
+process will not affect the following lines in the recipe.(1)  If you
+want to use `cd' to affect the next statement, put both statements in a
+single recipe line.  Then `make' will invoke one shell to run the
+entire line, and the shell will execute the statements in sequence.
+For example:
+
+     foo : bar/lose
+             cd $(@D) && gobble $(@F) > ../$@
+
+Here we use the shell AND operator (`&&') so that if the `cd' command
+fails, the script will fail without trying to invoke the `gobble'
+command in the wrong directory, which could cause problems (in this
+case it would certainly cause `../foo' to be truncated, at least).
+

+* One Shell::                   One shell for all lines in a recipe

+
+5.3.1 Using One Shell
+---------------------
+
+Sometimes you would prefer that all the lines in the recipe be passed
+to a single invocation of the shell.  There are generally two
+situations where this is useful: first, it can improve performance in
+makefiles where recipes consist of many command lines, by avoiding
+extra processes.  Second, you might want newlines to be included in
+your recipe command (for example perhaps you are using a very different
+interpreter as your `SHELL').  If the `.ONESHELL' special target
+appears anywhere in the makefile then _all_ recipe lines for each
+target will be provided to a single invocation of the shell.  Newlines
+between recipe lines will be preserved.  For example:
+
+     .ONESHELL:
+     foo : bar/lose
+             cd $(@D)
+             gobble $(@F) > ../$@
+
+would now work as expected even though the commands are on different
+recipe lines.
+
+   If `.ONESHELL' is provided, then only the first line of the recipe
+will be checked for the special prefix characters (`@', `-', and `+').
+Subsequent lines will include the special characters in the recipe line
+when the `SHELL' is invoked.  If you want your recipe to start with one
+of these special characters you'll need to arrange for them to not be
+the first characters on the first line, perhaps by adding a comment or
+similar.  For example, this would be a syntax error in Perl because the
+first `@' is removed by make:
+
+     .ONESHELL:
+     SHELL = /usr/bin/perl
+     .SHELLFLAGS = -e
+     show :
+             @f = qw(a b c);
+             print "@f\n";
+
+However, either of these alternatives would work properly:
+
+     .ONESHELL:
+     SHELL = /usr/bin/perl
+     .SHELLFLAGS = -e
+     show :
+             # Make sure "@" is not the first character on the first line
+             @f = qw(a b c);
+             print "@f\n";
+
+or
+
+     .ONESHELL:
+     SHELL = /usr/bin/perl
+     .SHELLFLAGS = -e
+     show :
+             my @f = qw(a b c);
+             print "@f\n";
+
+   As a special feature, if `SHELL' is determined to be a POSIX-style
+shell, the special prefix characters in "internal" recipe lines will
+_removed_ before the recipe is processed.  This feature is intended to
+allow existing makefiles to add the `.ONESHELL' special target and
+still run properly without extensive modifications.  Since the special
+prefix characters are not legal at the beginning of a line in a POSIX
+shell script this is not a loss in functionality.  For example, this
+works as expected:
+
+     .ONESHELL:
+     foo : bar/lose
+             @cd $(@D)
+             @gobble $(@F) > ../$@
+
+   Even with this special feature, however, makefiles with `.ONESHELL'
+will behave differently in ways that could be noticeable.  For example,
+normally if any line in the recipe fails, that causes the rule to fail
+and no more recipe lines are processed.  Under `.ONESHELL' a failure of
+any but the final recipe line will not be noticed by `make'.  You can
+modify `.SHELLFLAGS' to add the `-e' option to the shell which will
+cause any failure anywhere in the command line to cause the shell to
+fail, but this could itself cause your recipe to behave differently.
+Ultimately you may need to harden your recipe lines to allow them to
+work with `.ONESHELL'.

+
+5.3.2 Choosing the Shell
+------------------------
+
+The program used as the shell is taken from the variable `SHELL'.  If
+this variable is not set in your makefile, the program `/bin/sh' is
+used as the shell.  The argument(s) passed to the shell are taken from
+the variable `.SHELLFLAGS'.  The default value of `.SHELLFLAGS' is `-c'
+normally, or `-ec' in POSIX-conforming mode.
+
+   Unlike most variables, the variable `SHELL' is never set from the
+environment.  This is because the `SHELL' environment variable is used
+to specify your personal choice of shell program for interactive use.
+It would be very bad for personal choices like this to affect the
+functioning of makefiles.  *Note Variables from the Environment:
+Environment.
+
+   Furthermore, when you do set `SHELL' in your makefile that value is
+_not_ exported in the environment to recipe lines that `make' invokes.
+Instead, the value inherited from the user's environment, if any, is
+exported.  You can override this behavior by explicitly exporting
+`SHELL' (*note Communicating Variables to a Sub-`make':
+Variables/Recursion.), forcing it to be passed in the environment to
+recipe lines.
+
+   However, on MS-DOS and MS-Windows the value of `SHELL' in the
+environment *is* used, since on those systems most users do not set
+this variable, and therefore it is most likely set specifically to be
+used by `make'.  On MS-DOS, if the setting of `SHELL' is not suitable
+for `make', you can set the variable `MAKESHELL' to the shell that
+`make' should use; if set it will be used as the shell instead of the
+value of `SHELL'.
+
+Choosing a Shell in DOS and Windows
+...................................
+
+Choosing a shell in MS-DOS and MS-Windows is much more complex than on
+other systems.
+
+   On MS-DOS, if `SHELL' is not set, the value of the variable
+`COMSPEC' (which is always set) is used instead.
+
+   The processing of lines that set the variable `SHELL' in Makefiles
+is different on MS-DOS.  The stock shell, `command.com', is
+ridiculously limited in its functionality and many users of `make' tend
+to install a replacement shell.  Therefore, on MS-DOS, `make' examines
+the value of `SHELL', and changes its behavior based on whether it
+points to a Unix-style or DOS-style shell.  This allows reasonable
+functionality even if `SHELL' points to `command.com'.
+
+   If `SHELL' points to a Unix-style shell, `make' on MS-DOS
+additionally checks whether that shell can indeed be found; if not, it
+ignores the line that sets `SHELL'.  In MS-DOS, GNU `make' searches for
+the shell in the following places:
+
+  1. In the precise place pointed to by the value of `SHELL'.  For
+     example, if the makefile specifies `SHELL = /bin/sh', `make' will
+     look in the directory `/bin' on the current drive.
+
+  2. In the current directory.
+
+  3. In each of the directories in the `PATH' variable, in order.
+
+
+   In every directory it examines, `make' will first look for the
+specific file (`sh' in the example above).  If this is not found, it
+will also look in that directory for that file with one of the known
+extensions which identify executable files.  For example `.exe',
+`.com', `.bat', `.btm', `.sh', and some others.
+
+   If any of these attempts is successful, the value of `SHELL' will be
+set to the full pathname of the shell as found.  However, if none of
+these is found, the value of `SHELL' will not be changed, and thus the
+line that sets it will be effectively ignored.  This is so `make' will
+only support features specific to a Unix-style shell if such a shell is
+actually installed on the system where `make' runs.
+
+   Note that this extended search for the shell is limited to the cases
+where `SHELL' is set from the Makefile; if it is set in the environment
+or command line, you are expected to set it to the full pathname of the
+shell, exactly as things are on Unix.
+
+   The effect of the above DOS-specific processing is that a Makefile
+that contains `SHELL = /bin/sh' (as many Unix makefiles do), will work
+on MS-DOS unaltered if you have e.g. `sh.exe' installed in some
+directory along your `PATH'.

+File: make.info,  Node: Parallel,  Next: Errors,  Prev: Execution,  Up: Recipes
+
+5.4 Parallel Execution
+======================
+
+GNU `make' knows how to execute several recipes at once.  Normally,
+`make' will execute only one recipe at a time, waiting for it to finish
+before executing the next.  However, the `-j' or `--jobs' option tells
+`make' to execute many recipes simultaneously.  You can inhibit
+parallelism in a particular makefile with the `.NOTPARALLEL'
+pseudo-target (*note Special Built-in Target Names: Special Targets.).
+
+   On MS-DOS, the `-j' option has no effect, since that system doesn't
+support multi-processing.
+
+   If the `-j' option is followed by an integer, this is the number of
+recipes to execute at once; this is called the number of "job slots".
+If there is nothing looking like an integer after the `-j' option,
+there is no limit on the number of job slots.  The default number of job
+slots is one, which means serial execution (one thing at a time).
+
+   One unpleasant consequence of running several recipes simultaneously
+is that output generated by the recipes appears whenever each recipe
+sends it, so messages from different recipes may be interspersed.
+
+   Another problem is that two processes cannot both take input from the
+same device; so to make sure that only one recipe tries to take input
+from the terminal at once, `make' will invalidate the standard input
+streams of all but one running recipe.  This means that attempting to
+read from standard input will usually be a fatal error (a `Broken pipe'
+signal) for most child processes if there are several.  
+
+   It is unpredictable which recipe will have a valid standard input
+stream (which will come from the terminal, or wherever you redirect the
+standard input of `make').  The first recipe run will always get it
+first, and the first recipe started after that one finishes will get it
+next, and so on.
+
+   We will change how this aspect of `make' works if we find a better
+alternative.  In the mean time, you should not rely on any recipe using
+standard input at all if you are using the parallel execution feature;
+but if you are not using this feature, then standard input works
+normally in all recipes.
+
+   Finally, handling recursive `make' invocations raises issues.  For
+more information on this, see *note Communicating Options to a
+Sub-`make': Options/Recursion.
+
+   If a recipe fails (is killed by a signal or exits with a nonzero
+status), and errors are not ignored for that recipe (*note Errors in
+Recipes: Errors.), the remaining recipe lines to remake the same target
+will not be run.  If a recipe fails and the `-k' or `--keep-going'
+option was not given (*note Summary of Options: Options Summary.),
+`make' aborts execution.  If make terminates for any reason (including
+a signal) with child processes running, it waits for them to finish
+before actually exiting.
+
+   When the system is heavily loaded, you will probably want to run
+fewer jobs than when it is lightly loaded.  You can use the `-l' option
+to tell `make' to limit the number of jobs to run at once, based on the
+load average.  The `-l' or `--max-load' option is followed by a
+floating-point number.  For example,
+
+     -l 2.5
+
+will not let `make' start more than one job if the load average is
+above 2.5.  The `-l' option with no following number removes the load
+limit, if one was given with a previous `-l' option.
+
+   More precisely, when `make' goes to start up a job, and it already
+has at least one job running, it checks the current load average; if it
+is not lower than the limit given with `-l', `make' waits until the load
+average goes below that limit, or until all the other jobs finish.
+
+   By default, there is no load limit.

+
+5.5 Errors in Recipes
+=====================
+
+After each shell invocation returns, `make' looks at its exit status.
+If the shell completed successfully (the exit status is zero), the next
+line in the recipe is executed in a new shell; after the last line is
+finished, the rule is finished.
+
+   If there is an error (the exit status is nonzero), `make' gives up on
+the current rule, and perhaps on all rules.
+
+   Sometimes the failure of a certain recipe line does not indicate a
+problem.  For example, you may use the `mkdir' command to ensure that a
+directory exists.  If the directory already exists, `mkdir' will report
+an error, but you probably want `make' to continue regardless.
+
+   To ignore errors in a recipe line, write a `-' at the beginning of
+the line's text (after the initial tab).  The `-' is discarded before
+the line is passed to the shell for execution.
+
+   For example,
+
+     clean:
+             -rm -f *.o
+
+This causes `make' to continue even if `rm' is unable to remove a file.
+
+   When you run `make' with the `-i' or `--ignore-errors' flag, errors
+are ignored in all recipes of all rules.  A rule in the makefile for
+the special target `.IGNORE' has the same effect, if there are no
+prerequisites.  These ways of ignoring errors are obsolete because `-'
+is more flexible.
+
+   When errors are to be ignored, because of either a `-' or the `-i'
+flag, `make' treats an error return just like success, except that it
+prints out a message that tells you the status code the shell exited
+with, and says that the error has been ignored.
+
+   When an error happens that `make' has not been told to ignore, it
+implies that the current target cannot be correctly remade, and neither
+can any other that depends on it either directly or indirectly.  No
+further recipes will be executed for these targets, since their
+preconditions have not been achieved.
+
+   Normally `make' gives up immediately in this circumstance, returning
+a nonzero status.  However, if the `-k' or `--keep-going' flag is
+specified, `make' continues to consider the other prerequisites of the
+pending targets, remaking them if necessary, before it gives up and
+returns nonzero status.  For example, after an error in compiling one
+object file, `make -k' will continue compiling other object files even
+though it already knows that linking them will be impossible.  *Note
+Summary of Options: Options Summary.
+
+   The usual behavior assumes that your purpose is to get the specified
+targets up to date; once `make' learns that this is impossible, it
+might as well report the failure immediately.  The `-k' option says
+that the real purpose is to test as many of the changes made in the
+program as possible, perhaps to find several independent problems so
+that you can correct them all before the next attempt to compile.  This
+is why Emacs' `compile' command passes the `-k' flag by default.  
+
+   Usually when a recipe line fails, if it has changed the target file
+at all, the file is corrupted and cannot be used--or at least it is not
+completely updated.  Yet the file's time stamp says that it is now up to
+date, so the next time `make' runs, it will not try to update that
+file.  The situation is just the same as when the shell is killed by a
+signal; *note Interrupts::.  So generally the right thing to do is to
+delete the target file if the recipe fails after beginning to change
+the file.  `make' will do this if `.DELETE_ON_ERROR' appears as a
+target.  This is almost always what you want `make' to do, but it is
+not historical practice; so for compatibility, you must explicitly
+request it.

+
+5.6 Interrupting or Killing `make'
+==================================
+
+If `make' gets a fatal signal while a shell is executing, it may delete
+the target file that the recipe was supposed to update.  This is done
+if the target file's last-modification time has changed since `make'
+first checked it.
+
+   The purpose of deleting the target is to make sure that it is remade
+from scratch when `make' is next run.  Why is this?  Suppose you type
+`Ctrl-c' while a compiler is running, and it has begun to write an
+object file `foo.o'.  The `Ctrl-c' kills the compiler, resulting in an
+incomplete file whose last-modification time is newer than the source
+file `foo.c'.  But `make' also receives the `Ctrl-c' signal and deletes
+this incomplete file.  If `make' did not do this, the next invocation
+of `make' would think that `foo.o' did not require updating--resulting
+in a strange error message from the linker when it tries to link an
+object file half of which is missing.
+
+   You can prevent the deletion of a target file in this way by making
+the special target `.PRECIOUS' depend on it.  Before remaking a target,
+`make' checks to see whether it appears on the prerequisites of
+`.PRECIOUS', and thereby decides whether the target should be deleted
+if a signal happens.  Some reasons why you might do this are that the
+target is updated in some atomic fashion, or exists only to record a
+modification-time (its contents do not matter), or must exist at all
+times to prevent other sorts of trouble.
+

+File: make.info,  Node: Recursion,  Next: Canned Recipes,  Prev: Interrupts,  Up: Recipes
+
+5.7 Recursive Use of `make'
+===========================
+
+Recursive use of `make' means using `make' as a command in a makefile.
+This technique is useful when you want separate makefiles for various
+subsystems that compose a larger system.  For example, suppose you have
+a subdirectory `subdir' which has its own makefile, and you would like
+the containing directory's makefile to run `make' on the subdirectory.
+You can do it by writing this:
+
+     subsystem:
+             cd subdir && $(MAKE)
+
+or, equivalently, this (*note Summary of Options: Options Summary.):
+
+     subsystem:
+             $(MAKE) -C subdir
+   
+   You can write recursive `make' commands just by copying this example,
+but there are many things to know about how they work and why, and about
+how the sub-`make' relates to the top-level `make'.  You may also find
+it useful to declare targets that invoke recursive `make' commands as
+`.PHONY' (for more discussion on when this is useful, see *note Phony
+Targets::).
+
+   For your convenience, when GNU `make' starts (after it has processed
+any `-C' options) it sets the variable `CURDIR' to the pathname of the
+current working directory.  This value is never touched by `make'
+again: in particular note that if you include files from other
+directories the value of `CURDIR' does not change.  The value has the
+same precedence it would have if it were set in the makefile (by
+default, an environment variable `CURDIR' will not override this
+value).  Note that setting this variable has no impact on the operation
+of `make' (it does not cause `make' to change its working directory,
+for example).

+
+5.7.1 How the `MAKE' Variable Works
+-----------------------------------
+
+Recursive `make' commands should always use the variable `MAKE', not
+the explicit command name `make', as shown here:
+
+     subsystem:
+             cd subdir && $(MAKE)
+
+   The value of this variable is the file name with which `make' was
+invoked.  If this file name was `/bin/make', then the recipe executed
+is `cd subdir && /bin/make'.  If you use a special version of `make' to
+run the top-level makefile, the same special version will be executed
+for recursive invocations.  
+
+   As a special feature, using the variable `MAKE' in the recipe of a
+rule alters the effects of the `-t' (`--touch'), `-n' (`--just-print'),
+or `-q' (`--question') option.  Using the `MAKE' variable has the same
+effect as using a `+' character at the beginning of the recipe line.
+*Note Instead of Executing the Recipes: Instead of Execution.  This
+special feature is only enabled if the `MAKE' variable appears directly
+in the recipe: it does not apply if the `MAKE' variable is referenced
+through expansion of another variable.  In the latter case you must use
+the `+' token to get these special effects.
+
+   Consider the command `make -t' in the above example.  (The `-t'
+option marks targets as up to date without actually running any
+recipes; see *note Instead of Execution::.)  Following the usual
+definition of `-t', a `make -t' command in the example would create a
+file named `subsystem' and do nothing else.  What you really want it to
+do is run `cd subdir && make -t'; but that would require executing the
+recipe, and `-t' says not to execute recipes.  
+
+   The special feature makes this do what you want: whenever a recipe
+line of a rule contains the variable `MAKE', the flags `-t', `-n' and
+`-q' do not apply to that line.  Recipe lines containing `MAKE' are
+executed normally despite the presence of a flag that causes most
+recipes not to be run.  The usual `MAKEFLAGS' mechanism passes the
+flags to the sub-`make' (*note Communicating Options to a Sub-`make':
+Options/Recursion.), so your request to touch the files, or print the
+recipes, is propagated to the subsystem.
+
+
+File: make.info,  Node: Variables/Recursion,  Next: Options/Recursion,  Prev: MAKE Variable,  Up: Recursion
+
+5.7.2 Communicating Variables to a Sub-`make'
+---------------------------------------------
+
+Variable values of the top-level `make' can be passed to the sub-`make'
+through the environment by explicit request.  These variables are
+defined in the sub-`make' as defaults, but do not override what is
+specified in the makefile used by the sub-`make' makefile unless you
+use the `-e' switch (*note Summary of Options: Options Summary.).
+
+   To pass down, or "export", a variable, `make' adds the variable and
+its value to the environment for running each line of the recipe.  The
+sub-`make', in turn, uses the environment to initialize its table of
+variable values.  *Note Variables from the Environment: Environment.
+
+   Except by explicit request, `make' exports a variable only if it is
+either defined in the environment initially or set on the command line,
+and if its name consists only of letters, numbers, and underscores.
+Some shells cannot cope with environment variable names consisting of
+characters other than letters, numbers, and underscores.
+
+   The value of the `make' variable `SHELL' is not exported.  Instead,
+the value of the `SHELL' variable from the invoking environment is
+passed to the sub-`make'.  You can force `make' to export its value for
+`SHELL' by using the `export' directive, described below.  *Note
+Choosing the Shell::.
+
+   The special variable `MAKEFLAGS' is always exported (unless you
+unexport it).  `MAKEFILES' is exported if you set it to anything.
+
+   `make' automatically passes down variable values that were defined
+on the command line, by putting them in the `MAKEFLAGS' variable.
+*Note Options/Recursion::.
+
+   Variables are _not_ normally passed down if they were created by
+default by `make' (*note Variables Used by Implicit Rules: Implicit
+Variables.).  The sub-`make' will define these for itself.
+
+   If you want to export specific variables to a sub-`make', use the
+`export' directive, like this:
+
+     export VARIABLE ...
+
+If you want to _prevent_ a variable from being exported, use the
+`unexport' directive, like this:
+
+     unexport VARIABLE ...
+
+In both of these forms, the arguments to `export' and `unexport' are
+expanded, and so could be variables or functions which expand to a
+(list of) variable names to be (un)exported.
+
+   As a convenience, you can define a variable and export it at the same
+time by doing:
+
+     export VARIABLE = value
+
+has the same result as:
+
+     VARIABLE = value
+     export VARIABLE
+
+and
+
+     export VARIABLE := value
+
+has the same result as:
+
+     VARIABLE := value
+     export VARIABLE
+
+   Likewise,
+
+     export VARIABLE += value
+
+is just like:
+
+     VARIABLE += value
+     export VARIABLE
+
+*Note Appending More Text to Variables: Appending.
+
+   You may notice that the `export' and `unexport' directives work in
+`make' in the same way they work in the shell, `sh'.
+
+   If you want all variables to be exported by default, you can use
+`export' by itself:
+
+     export
+
+This tells `make' that variables which are not explicitly mentioned in
+an `export' or `unexport' directive should be exported.  Any variable
+given in an `unexport' directive will still _not_ be exported.  If you
+use `export' by itself to export variables by default, variables whose
+names contain characters other than alphanumerics and underscores will
+not be exported unless specifically mentioned in an `export' directive.
+
+   The behavior elicited by an `export' directive by itself was the
+default in older versions of GNU `make'.  If your makefiles depend on
+this behavior and you want to be compatible with old versions of
+`make', you can write a rule for the special target
+`.EXPORT_ALL_VARIABLES' instead of using the `export' directive.  This
+will be ignored by old `make's, while the `export' directive will cause
+a syntax error.  
+
+   Likewise, you can use `unexport' by itself to tell `make' _not_ to
+export variables by default.  Since this is the default behavior, you
+would only need to do this if `export' had been used by itself earlier
+(in an included makefile, perhaps).  You *cannot* use `export' and
+`unexport' by themselves to have variables exported for some recipes
+and not for others.  The last `export' or `unexport' directive that
+appears by itself determines the behavior for the entire run of `make'.
+
+   As a special feature, the variable `MAKELEVEL' is changed when it is
+passed down from level to level.  This variable's value is a string
+which is the depth of the level as a decimal number.  The value is `0'
+for the top-level `make'; `1' for a sub-`make', `2' for a
+sub-sub-`make', and so on.  The incrementation happens when `make' sets
+up the environment for a recipe.
+
+   The main use of `MAKELEVEL' is to test it in a conditional directive
+(*note Conditional Parts of Makefiles: Conditionals.); this way you can
+write a makefile that behaves one way if run recursively and another
+way if run directly by you.
+
+   You can use the variable `MAKEFILES' to cause all sub-`make'
+commands to use additional makefiles.  The value of `MAKEFILES' is a
+whitespace-separated list of file names.  This variable, if defined in
+the outer-level makefile, is passed down through the environment; then
+it serves as a list of extra makefiles for the sub-`make' to read
+before the usual or specified ones.  *Note The Variable `MAKEFILES':
+MAKEFILES Variable.

+
+5.7.3 Communicating Options to a Sub-`make'
+-------------------------------------------
+
+Flags such as `-s' and `-k' are passed automatically to the sub-`make'
+through the variable `MAKEFLAGS'.  This variable is set up
+automatically by `make' to contain the flag letters that `make'
+received.  Thus, if you do `make -ks' then `MAKEFLAGS' gets the value
+`ks'.
+
+   As a consequence, every sub-`make' gets a value for `MAKEFLAGS' in
+its environment.  In response, it takes the flags from that value and
+processes them as if they had been given as arguments.  *Note Summary
+of Options: Options Summary.
+
+   Likewise variables defined on the command line are passed to the
+sub-`make' through `MAKEFLAGS'.  Words in the value of `MAKEFLAGS' that
+contain `=', `make' treats as variable definitions just as if they
+appeared on the command line.  *Note Overriding Variables: Overriding.
+
+   The options `-C', `-f', `-o', and `-W' are not put into `MAKEFLAGS';
+these options are not passed down.
+
+   The `-j' option is a special case (*note Parallel Execution:
+Parallel.).  If you set it to some numeric value `N' and your operating
+system supports it (most any UNIX system will; others typically won't),
+the parent `make' and all the sub-`make's will communicate to ensure
+that there are only `N' jobs running at the same time between them all.
+Note that any job that is marked recursive (*note Instead of Executing
+Recipes: Instead of Execution.)  doesn't count against the total jobs
+(otherwise we could get `N' sub-`make's running and have no slots left
+over for any real work!)
+
+   If your operating system doesn't support the above communication,
+then `-j 1' is always put into `MAKEFLAGS' instead of the value you
+specified.  This is because if the `-j' option were passed down to
+sub-`make's, you would get many more jobs running in parallel than you
+asked for.  If you give `-j' with no numeric argument, meaning to run
+as many jobs as possible in parallel, this is passed down, since
+multiple infinities are no more than one.
+
+   If you do not want to pass the other flags down, you must change the
+value of `MAKEFLAGS', like this:
+
+     subsystem:
+             cd subdir && $(MAKE) MAKEFLAGS=
+
+   The command line variable definitions really appear in the variable
+`MAKEOVERRIDES', and `MAKEFLAGS' contains a reference to this variable.
+If you do want to pass flags down normally, but don't want to pass down
+the command line variable definitions, you can reset `MAKEOVERRIDES' to
+empty, like this:
+
+     MAKEOVERRIDES =
+
+This is not usually useful to do.  However, some systems have a small
+fixed limit on the size of the environment, and putting so much
+information into the value of `MAKEFLAGS' can exceed it.  If you see
+the error message `Arg list too long', this may be the problem.  (For
+strict compliance with POSIX.2, changing `MAKEOVERRIDES' does not
+affect `MAKEFLAGS' if the special target `.POSIX' appears in the
+makefile.  You probably do not care about this.)
+
+   A similar variable `MFLAGS' exists also, for historical
+compatibility.  It has the same value as `MAKEFLAGS' except that it
+does not contain the command line variable definitions, and it always
+begins with a hyphen unless it is empty (`MAKEFLAGS' begins with a
+hyphen only when it begins with an option that has no single-letter
+version, such as `--warn-undefined-variables').  `MFLAGS' was
+traditionally used explicitly in the recursive `make' command, like
+this:
+
+     subsystem:
+             cd subdir && $(MAKE) $(MFLAGS)
+
+but now `MAKEFLAGS' makes this usage redundant.  If you want your
+makefiles to be compatible with old `make' programs, use this
+technique; it will work fine with more modern `make' versions too.
+
+   The `MAKEFLAGS' variable can also be useful if you want to have
+certain options, such as `-k' (*note Summary of Options: Options
+Summary.), set each time you run `make'.  You simply put a value for
+`MAKEFLAGS' in your environment.  You can also set `MAKEFLAGS' in a
+makefile, to specify additional flags that should also be in effect for
+that makefile.  (Note that you cannot use `MFLAGS' this way.  That
+variable is set only for compatibility; `make' does not interpret a
+value you set for it in any way.)
+
+   When `make' interprets the value of `MAKEFLAGS' (either from the
+environment or from a makefile), it first prepends a hyphen if the value
+does not already begin with one.  Then it chops the value into words
+separated by blanks, and parses these words as if they were options
+given on the command line (except that `-C', `-f', `-h', `-o', `-W',
+and their long-named versions are ignored; and there is no error for an
+invalid option).
+
+   If you do put `MAKEFLAGS' in your environment, you should be sure not
+to include any options that will drastically affect the actions of
+`make' and undermine the purpose of makefiles and of `make' itself.
+For instance, the `-t', `-n', and `-q' options, if put in one of these
+variables, could have disastrous consequences and would certainly have
+at least surprising and probably annoying effects.

+
+5.7.4 The `--print-directory' Option
+------------------------------------
+
+If you use several levels of recursive `make' invocations, the `-w' or
+`--print-directory' option can make the output a lot easier to
+understand by showing each directory as `make' starts processing it and
+as `make' finishes processing it.  For example, if `make -w' is run in
+the directory `/u/gnu/make', `make' will print a line of the form:
+
+     make: Entering directory `/u/gnu/make'.
+
+before doing anything else, and a line of the form:
+
+     make: Leaving directory `/u/gnu/make'.
+
+when processing is completed.
+
+   Normally, you do not need to specify this option because `make' does
+it for you: `-w' is turned on automatically when you use the `-C'
+option, and in sub-`make's.  `make' will not automatically turn on `-w'
+if you also use `-s', which says to be silent, or if you use
+`--no-print-directory' to explicitly disable it.

+
+5.8 Defining Canned Recipes
+===========================
+
+When the same sequence of commands is useful in making various targets,
+you can define it as a canned sequence with the `define' directive, and
+refer to the canned sequence from the recipes for those targets.  The
+canned sequence is actually a variable, so the name must not conflict
+with other variable names.
+
+   Here is an example of defining a canned recipe:
+
+     define run-yacc =
+     yacc $(firstword $^)
+     mv y.tab.c $@
+     endef
+   
+Here `run-yacc' is the name of the variable being defined; `endef'
+marks the end of the definition; the lines in between are the commands.
+The `define' directive does not expand variable references and function
+calls in the canned sequence; the `$' characters, parentheses, variable
+names, and so on, all become part of the value of the variable you are
+defining.  *Note Defining Multi-Line Variables: Multi-Line, for a
+complete explanation of `define'.
+
+   The first command in this example runs Yacc on the first
+prerequisite of whichever rule uses the canned sequence.  The output
+file from Yacc is always named `y.tab.c'.  The second command moves the
+output to the rule's target file name.
+
+   To use the canned sequence, substitute the variable into the recipe
+of a rule.  You can substitute it like any other variable (*note Basics
+of Variable References: Reference.).  Because variables defined by
+`define' are recursively expanded variables, all the variable
+references you wrote inside the `define' are expanded now.  For example:
+
+     foo.c : foo.y
+             $(run-yacc)
+
+`foo.y' will be substituted for the variable `$^' when it occurs in
+`run-yacc''s value, and `foo.c' for `$@'.
+
+   This is a realistic example, but this particular one is not needed in
+practice because `make' has an implicit rule to figure out these
+commands based on the file names involved (*note Using Implicit Rules:
+Implicit Rules.).
+
+   In recipe execution, each line of a canned sequence is treated just
+as if the line appeared on its own in the rule, preceded by a tab.  In
+particular, `make' invokes a separate subshell for each line.  You can
+use the special prefix characters that affect command lines (`@', `-',
+and `+') on each line of a canned sequence.  *Note Writing Recipes in
+Rules: Recipes.  For example, using this canned sequence:
+
+     define frobnicate =
+     @echo "frobnicating target $@"
+     frob-step-1 $< -o $@-step-1
+     frob-step-2 $@-step-1 -o $@
+     endef
+
+`make' will not echo the first line, the `echo' command.  But it _will_
+echo the following two recipe lines.
+
+   On the other hand, prefix characters on the recipe line that refers
+to a canned sequence apply to every line in the sequence.  So the rule:
+
+     frob.out: frob.in
+             @$(frobnicate)
+
+does not echo _any_ recipe lines.  (*Note Recipe Echoing: Echoing, for
+a full explanation of `@'.)
+

+
+5.9 Using Empty Recipes
+=======================
+
+It is sometimes useful to define recipes which do nothing.  This is done
+simply by giving a recipe that consists of nothing but whitespace.  For
+example:
+
+     target: ;
+
+defines an empty recipe for `target'.  You could also use a line
+beginning with a recipe prefix character to define an empty recipe, but
+this would be confusing because such a line looks empty.
+
+   You may be wondering why you would want to define a recipe that does
+nothing.  The only reason this is useful is to prevent a target from
+getting implicit recipes (from implicit rules or the `.DEFAULT' special
+target; *note Implicit Rules:: and *note Defining Last-Resort Default
+Rules: Last Resort.).
+
+   You may be inclined to define empty recipes for targets that are not
+actual files, but only exist so that their prerequisites can be remade.
+However, this is not the best way to do that, because the prerequisites
+may not be remade properly if the target file actually does exist.
+*Note Phony Targets: Phony Targets, for a better way to do this.

+
+6 How to Use Variables
+**********************
+
+A "variable" is a name defined in a makefile to represent a string of
+text, called the variable's "value".  These values are substituted by
+explicit request into targets, prerequisites, recipes, and other parts
+of the makefile.  (In some other versions of `make', variables are
+called "macros".)  
+
+   Variables and functions in all parts of a makefile are expanded when
+read, except for in recipes, the right-hand sides of variable
+definitions using `=', and the bodies of variable definitions using the
+`define' directive.
+
+   Variables can represent lists of file names, options to pass to
+compilers, programs to run, directories to look in for source files,
+directories to write output in, or anything else you can imagine.
+
+   A variable name may be any sequence of characters not containing `:',
+`#', `=', or leading or trailing whitespace.  However, variable names
+containing characters other than letters, numbers, and underscores
+should be avoided, as they may be given special meanings in the future,
+and with some shells they cannot be passed through the environment to a
+sub-`make' (*note Communicating Variables to a Sub-`make':
+Variables/Recursion.).
+
+   Variable names are case-sensitive.  The names `foo', `FOO', and
+`Foo' all refer to different variables.
+
+   It is traditional to use upper case letters in variable names, but we
+recommend using lower case letters for variable names that serve
+internal purposes in the makefile, and reserving upper case for
+parameters that control implicit rules or for parameters that the user
+should override with command options (*note Overriding Variables:
+Overriding.).
+
+   A few variables have names that are a single punctuation character or
+just a few characters.  These are the "automatic variables", and they
+have particular specialized uses.  *Note Automatic Variables::.

+
+6.1 Basics of Variable References
+=================================
+
+To substitute a variable's value, write a dollar sign followed by the
+name of the variable in parentheses or braces: either `$(foo)' or
+`${foo}' is a valid reference to the variable `foo'.  This special
+significance of `$' is why you must write `$$' to have the effect of a
+single dollar sign in a file name or recipe.
+
+   Variable references can be used in any context: targets,
+prerequisites, recipes, most directives, and new variable values.  Here
+is an example of a common case, where a variable holds the names of all
+the object files in a program:
+
+     objects = program.o foo.o utils.o
+     program : $(objects)
+             cc -o program $(objects)
+
+     $(objects) : defs.h
+
+   Variable references work by strict textual substitution.  Thus, the
+rule
+
+     foo = c
+     prog.o : prog.$(foo)
+             $(foo)$(foo) -$(foo) prog.$(foo)
+
+could be used to compile a C program `prog.c'.  Since spaces before the
+variable value are ignored in variable assignments, the value of `foo'
+is precisely `c'.  (Don't actually write your makefiles this way!)
+
+   A dollar sign followed by a character other than a dollar sign,
+open-parenthesis or open-brace treats that single character as the
+variable name.  Thus, you could reference the variable `x' with `$x'.
+However, this practice is strongly discouraged, except in the case of
+the automatic variables (*note Automatic Variables::).
+
+
+File: make.info,  Node: Flavors,  Next: Advanced,  Prev: Reference,  Up: Using Variables
+
+6.2 The Two Flavors of Variables
+================================
+
+There are two ways that a variable in GNU `make' can have a value; we
+call them the two "flavors" of variables.  The two flavors are
+distinguished in how they are defined and in what they do when expanded.
+
+   The first flavor of variable is a "recursively expanded" variable.
+Variables of this sort are defined by lines using `=' (*note Setting
+Variables: Setting.) or by the `define' directive (*note Defining
+Multi-Line Variables: Multi-Line.).  The value you specify is installed
+verbatim; if it contains references to other variables, these
+references are expanded whenever this variable is substituted (in the
+course of expanding some other string).  When this happens, it is
+called "recursive expansion".
+
+   For example,
+
+     foo = $(bar)
+     bar = $(ugh)
+     ugh = Huh?
+
+     all:;echo $(foo)
+
+will echo `Huh?': `$(foo)' expands to `$(bar)' which expands to
+`$(ugh)' which finally expands to `Huh?'.
+
+   This flavor of variable is the only sort supported by other versions
+of `make'.  It has its advantages and its disadvantages.  An advantage
+(most would say) is that:
+
+     CFLAGS = $(include_dirs) -O
+     include_dirs = -Ifoo -Ibar
+
+will do what was intended: when `CFLAGS' is expanded in a recipe, it
+will expand to `-Ifoo -Ibar -O'.  A major disadvantage is that you
+cannot append something on the end of a variable, as in
+
+     CFLAGS = $(CFLAGS) -O
+
+because it will cause an infinite loop in the variable expansion.
+(Actually `make' detects the infinite loop and reports an error.)  
+
+   Another disadvantage is that any functions (*note Functions for
+Transforming Text: Functions.)  referenced in the definition will be
+executed every time the variable is expanded.  This makes `make' run
+slower; worse, it causes the `wildcard' and `shell' functions to give
+unpredictable results because you cannot easily control when they are
+called, or even how many times.
+
+   To avoid all the problems and inconveniences of recursively expanded
+variables, there is another flavor: simply expanded variables.
+
+   "Simply expanded variables" are defined by lines using `:=' (*note
+Setting Variables: Setting.).  The value of a simply expanded variable
+is scanned once and for all, expanding any references to other
+variables and functions, when the variable is defined.  The actual
+value of the simply expanded variable is the result of expanding the
+text that you write.  It does not contain any references to other
+variables; it contains their values _as of the time this variable was
+defined_.  Therefore,
+
+     x := foo
+     y := $(x) bar
+     x := later
+
+is equivalent to
+
+     y := foo bar
+     x := later
+
+   When a simply expanded variable is referenced, its value is
+substituted verbatim.
+
+   Here is a somewhat more complicated example, illustrating the use of
+`:=' in conjunction with the `shell' function.  (*Note The `shell'
+Function: Shell Function.)  This example also shows use of the variable
+`MAKELEVEL', which is changed when it is passed down from level to
+level.  (*Note Communicating Variables to a Sub-`make':
+Variables/Recursion, for information about `MAKELEVEL'.)
+
+     ifeq (0,${MAKELEVEL})
+     whoami    := $(shell whoami)
+     host-type := $(shell arch)
+     MAKE := ${MAKE} host-type=${host-type} whoami=${whoami}
+     endif
+
+An advantage of this use of `:=' is that a typical `descend into a
+directory' recipe then looks like this:
+
+     ${subdirs}:
+             ${MAKE} -C $@ all
+
+   Simply expanded variables generally make complicated makefile
+programming more predictable because they work like variables in most
+programming languages.  They allow you to redefine a variable using its
+own value (or its value processed in some way by one of the expansion
+functions) and to use the expansion functions much more efficiently
+(*note Functions for Transforming Text: Functions.).
+
+   You can also use them to introduce controlled leading whitespace into
+variable values.  Leading whitespace characters are discarded from your
+input before substitution of variable references and function calls;
+this means you can include leading spaces in a variable value by
+protecting them with variable references, like this:
+
+     nullstring :=
+     space := $(nullstring) # end of the line
+
+Here the value of the variable `space' is precisely one space.  The
+comment `# end of the line' is included here just for clarity.  Since
+trailing space characters are _not_ stripped from variable values, just
+a space at the end of the line would have the same effect (but be
+rather hard to read).  If you put whitespace at the end of a variable
+value, it is a good idea to put a comment like that at the end of the
+line to make your intent clear.  Conversely, if you do _not_ want any
+whitespace characters at the end of your variable value, you must
+remember not to put a random comment on the end of the line after some
+whitespace, such as this:
+
+     dir := /foo/bar    # directory to put the frobs in
+
+Here the value of the variable `dir' is `/foo/bar    ' (with four
+trailing spaces), which was probably not the intention.  (Imagine
+something like `$(dir)/file' with this definition!)
+
+   There is another assignment operator for variables, `?='.  This is
+called a conditional variable assignment operator, because it only has
+an effect if the variable is not yet defined.  This statement:
+
+     FOO ?= bar
+
+is exactly equivalent to this (*note The `origin' Function: Origin
+Function.):
+
+     ifeq ($(origin FOO), undefined)
+       FOO = bar
+     endif
+
+   Note that a variable set to an empty value is still defined, so `?='
+will not set that variable.

+6.3 Advanced Features for Reference to Variables
+================================================
+
+This section describes some advanced features you can use to reference
+variables in more flexible ways.
+
+* Menu:
+
+* Substitution Refs::           Referencing a variable with
+                                  substitutions on the value.
+* Computed Names::              Computing the name of the variable to refer to.
+
+
+File: make.info,  Node: Substitution Refs,  Next: Computed Names,  Prev: Advanced,  Up: Advanced
+
+6.3.1 Substitution References
+-----------------------------
+
+A "substitution reference" substitutes the value of a variable with
+alterations that you specify.  It has the form `$(VAR:A=B)' (or
+`${VAR:A=B}') and its meaning is to take the value of the variable VAR,
+replace every A at the end of a word with B in that value, and
+substitute the resulting string.
+
+   When we say "at the end of a word", we mean that A must appear
+either followed by whitespace or at the end of the value in order to be
+replaced; other occurrences of A in the value are unaltered.  For
+example:
+
+     foo := a.o b.o c.o
+     bar := $(foo:.o=.c)
+
+sets `bar' to `a.c b.c c.c'.  *Note Setting Variables: Setting.
+
+   A substitution reference is actually an abbreviation for use of the
+`patsubst' expansion function (*note Functions for String Substitution
+and Analysis: Text Functions.).  We provide substitution references as
+well as `patsubst' for compatibility with other implementations of
+`make'.
+
+   Another type of substitution reference lets you use the full power of
+the `patsubst' function.  It has the same form `$(VAR:A=B)' described
+above, except that now A must contain a single `%' character.  This
+case is equivalent to `$(patsubst A,B,$(VAR))'.  *Note Functions for
+String Substitution and Analysis: Text Functions, for a description of
+the `patsubst' function.
+
+For example:
+
+     foo := a.o b.o c.o
+     bar := $(foo:%.o=%.c)
+
+sets `bar' to `a.c b.c c.c'.

+
+6.3.2 Computed Variable Names
+-----------------------------
+
+Computed variable names are a complicated concept needed only for
+sophisticated makefile programming.  For most purposes you need not
+consider them, except to know that making a variable with a dollar sign
+in its name might have strange results.  However, if you are the type
+that wants to understand everything, or you are actually interested in
+what they do, read on.
+
+   Variables may be referenced inside the name of a variable.  This is
+called a "computed variable name" or a "nested variable reference".
+For example,
+
+     x = y
+     y = z
+     a := $($(x))
+
+defines `a' as `z': the `$(x)' inside `$($(x))' expands to `y', so
+`$($(x))' expands to `$(y)' which in turn expands to `z'.  Here the
+name of the variable to reference is not stated explicitly; it is
+computed by expansion of `$(x)'.  The reference `$(x)' here is nested
+within the outer variable reference.
+
+   The previous example shows two levels of nesting, but any number of
+levels is possible.  For example, here are three levels:
+
+     x = y
+     y = z
+     z = u
+     a := $($($(x)))
+
+Here the innermost `$(x)' expands to `y', so `$($(x))' expands to
+`$(y)' which in turn expands to `z'; now we have `$(z)', which becomes
+`u'.
+
+   References to recursively-expanded variables within a variable name
+are reexpanded in the usual fashion.  For example:
+
+     x = $(y)
+     y = z
+     z = Hello
+     a := $($(x))
+
+defines `a' as `Hello': `$($(x))' becomes `$($(y))' which becomes
+`$(z)' which becomes `Hello'.
+
+   Nested variable references can also contain modified references and
+function invocations (*note Functions for Transforming Text:
+Functions.), just like any other reference.  For example, using the
+`subst' function (*note Functions for String Substitution and Analysis:
+Text Functions.):
+
+     x = variable1
+     variable2 := Hello
+     y = $(subst 1,2,$(x))
+     z = y
+     a := $($($(z)))
+
+eventually defines `a' as `Hello'.  It is doubtful that anyone would
+ever want to write a nested reference as convoluted as this one, but it
+works: `$($($(z)))' expands to `$($(y))' which becomes `$($(subst
+1,2,$(x)))'.  This gets the value `variable1' from `x' and changes it
+by substitution to `variable2', so that the entire string becomes
+`$(variable2)', a simple variable reference whose value is `Hello'.
+
+   A computed variable name need not consist entirely of a single
+variable reference.  It can contain several variable references, as
+well as some invariant text.  For example,
+
+     a_dirs := dira dirb
+     1_dirs := dir1 dir2
+
+     a_files := filea fileb
+     1_files := file1 file2
+
+     ifeq "$(use_a)" "yes"
+     a1 := a
+     else
+     a1 := 1
+     endif
+
+     ifeq "$(use_dirs)" "yes"
+     df := dirs
+     else
+     df := files
+     endif
+
+     dirs := $($(a1)_$(df))
+
+will give `dirs' the same value as `a_dirs', `1_dirs', `a_files' or
+`1_files' depending on the settings of `use_a' and `use_dirs'.
+
+   Computed variable names can also be used in substitution references:
+
+     a_objects := a.o b.o c.o
+     1_objects := 1.o 2.o 3.o
+
+     sources := $($(a1)_objects:.o=.c)
+
+defines `sources' as either `a.c b.c c.c' or `1.c 2.c 3.c', depending
+on the value of `a1'.
+
+   The only restriction on this sort of use of nested variable
+references is that they cannot specify part of the name of a function
+to be called.  This is because the test for a recognized function name
+is done before the expansion of nested references.  For example,
+
+     ifdef do_sort
+     func := sort
+     else
+     func := strip
+     endif
+
+     bar := a d b g q c
+
+     foo := $($(func) $(bar))
+
+attempts to give `foo' the value of the variable `sort a d b g q c' or
+`strip a d b g q c', rather than giving `a d b g q c' as the argument
+to either the `sort' or the `strip' function.  This restriction could
+be removed in the future if that change is shown to be a good idea.
+
+   You can also use computed variable names in the left-hand side of a
+variable assignment, or in a `define' directive, as in:
+
+     dir = foo
+     $(dir)_sources := $(wildcard $(dir)/*.c)
+     define $(dir)_print =
+     lpr $($(dir)_sources)
+     endef
+
+This example defines the variables `dir', `foo_sources', and
+`foo_print'.

+"recursively expanded variables" (*note The Two Flavors of Variables:
+Flavors.), though both are used together in complex ways when doing
+makefile programming.

+6.4 How Variables Get Their Values
+==================================
+
+Variables can get values in several different ways:
+
+   * You can specify an overriding value when you run `make'.  *Note
+     Overriding Variables: Overriding.
+
+   * You can specify a value in the makefile, either with an assignment
+     (*note Setting Variables: Setting.) or with a verbatim definition
+     (*note Defining Multi-Line Variables: Multi-Line.).
+
+   * Variables in the environment become `make' variables.  *Note
+     Variables from the Environment: Environment.
+
+   * Several "automatic" variables are given new values for each rule.
+     Each of these has a single conventional use.  *Note Automatic
+     Variables::.
+
+   * Several variables have constant initial values.  *Note Variables
+     Used by Implicit Rules: Implicit Variables.
+
+
+File: make.info,  Node: Setting,  Next: Appending,  Prev: Values,  Up: Using Variables
+
+6.5 Setting Variables
+=====================
+
+To set a variable from the makefile, write a line starting with the
+variable name followed by `=' or `:='.  Whatever follows the `=' or
+`:=' on the line becomes the value.  For example,
+
+     objects = main.o foo.o bar.o utils.o
+
+defines a variable named `objects'.  Whitespace around the variable
+name and immediately after the `=' is ignored.
+
+   Variables defined with `=' are "recursively expanded" variables.
+Variables defined with `:=' are "simply expanded" variables; these
+definitions can contain variable references which will be expanded
+before the definition is made.  *Note The Two Flavors of Variables:
+Flavors.
+
+   The variable name may contain function and variable references, which
+are expanded when the line is read to find the actual variable name to
+use.
+
+   There is no limit on the length of the value of a variable except the
+amount of swapping space on the computer.  When a variable definition is
+long, it is a good idea to break it into several lines by inserting
+backslash-newline at convenient places in the definition.  This will not
+affect the functioning of `make', but it will make the makefile easier
+to read.
+
+   Most variable names are considered to have the empty string as a
+value if you have never set them.  Several variables have built-in
+initial values that are not empty, but you can set them in the usual
+ways (*note Variables Used by Implicit Rules: Implicit Variables.).
+Several special variables are set automatically to a new value for each
+rule; these are called the "automatic" variables (*note Automatic
+Variables::).
+
+   If you'd like a variable to be set to a value only if it's not
+already set, then you can use the shorthand operator `?=' instead of
+`='.  These two settings of the variable `FOO' are identical (*note The
+`origin' Function: Origin Function.):
+
+     FOO ?= bar
+
+and
+
+     ifeq ($(origin FOO), undefined)
+     FOO = bar
+     endif

+
+6.6 Appending More Text to Variables
+====================================
+
+Often it is useful to add more text to the value of a variable already
+defined.  You do this with a line containing `+=', like this:
+
+     objects += another.o
+
+This takes the value of the variable `objects', and adds the text
+`another.o' to it (preceded by a single space).  Thus:
+
+     objects = main.o foo.o bar.o utils.o
+     objects += another.o
+
+sets `objects' to `main.o foo.o bar.o utils.o another.o'.
+
+   Using `+=' is similar to:
+
+     objects = main.o foo.o bar.o utils.o
+     objects := $(objects) another.o
+
+but differs in ways that become important when you use more complex
+values.
+
+   When the variable in question has not been defined before, `+=' acts
+just like normal `=': it defines a recursively-expanded variable.
+However, when there _is_ a previous definition, exactly what `+=' does
+depends on what flavor of variable you defined originally.  *Note The
+Two Flavors of Variables: Flavors, for an explanation of the two
+flavors of variables.
+
+   When you add to a variable's value with `+=', `make' acts
+essentially as if you had included the extra text in the initial
+definition of the variable.  If you defined it first with `:=', making
+it a simply-expanded variable, `+=' adds to that simply-expanded
+definition, and expands the new text before appending it to the old
+value just as `:=' does (see *note Setting Variables: Setting, for a
+full explanation of `:=').  In fact,
+
+     variable := value
+     variable += more
+
+is exactly equivalent to:
+
+
+     variable := value
+     variable := $(variable) more
+
+   On the other hand, when you use `+=' with a variable that you defined
+first to be recursively-expanded using plain `=', `make' does something
+a bit different.  Recall that when you define a recursively-expanded
+variable, `make' does not expand the value you set for variable and
+function references immediately.  Instead it stores the text verbatim,
+and saves these variable and function references to be expanded later,
+when you refer to the new variable (*note The Two Flavors of Variables:
+Flavors.).  When you use `+=' on a recursively-expanded variable, it is
+this unexpanded text to which `make' appends the new text you specify.
+
+     variable = value
+     variable += more
+
+is roughly equivalent to:
+
+     temp = value
+     variable = $(temp) more
+
+except that of course it never defines a variable called `temp'.  The
+importance of this comes when the variable's old value contains
+variable references.  Take this common example:
+
+     CFLAGS = $(includes) -O
+     ...
+     CFLAGS += -pg # enable profiling
+
+The first line defines the `CFLAGS' variable with a reference to another
+variable, `includes'.  (`CFLAGS' is used by the rules for C
+compilation; *note Catalogue of Implicit Rules: Catalogue of Rules.)
+Using `=' for the definition makes `CFLAGS' a recursively-expanded
+variable, meaning `$(includes) -O' is _not_ expanded when `make'
+processes the definition of `CFLAGS'.  Thus, `includes' need not be
+defined yet for its value to take effect.  It only has to be defined
+before any reference to `CFLAGS'.  If we tried to append to the value
+of `CFLAGS' without using `+=', we might do it like this:
+
+     CFLAGS := $(CFLAGS) -pg # enable profiling
+
+This is pretty close, but not quite what we want.  Using `:=' redefines
+`CFLAGS' as a simply-expanded variable; this means `make' expands the
+text `$(CFLAGS) -pg' before setting the variable.  If `includes' is not
+yet defined, we get ` -O -pg', and a later definition of `includes'
+will have no effect.  Conversely, by using `+=' we set `CFLAGS' to the
+_unexpanded_ value `$(includes) -O -pg'.  Thus we preserve the
+reference to `includes', so if that variable gets defined at any later
+point, a reference like `$(CFLAGS)' still uses its value.

+
+6.7 The `override' Directive
+============================
+
+If a variable has been set with a command argument (*note Overriding
+Variables: Overriding.), then ordinary assignments in the makefile are
+ignored.  If you want to set the variable in the makefile even though
+it was set with a command argument, you can use an `override'
+directive, which is a line that looks like this:
+
+     override VARIABLE = VALUE
+
+or
+
+     override VARIABLE := VALUE
+
+   To append more text to a variable defined on the command line, use:
+
+     override VARIABLE += MORE TEXT
+
+*Note Appending More Text to Variables: Appending.
+
+   Variable assignments marked with the `override' flag have a higher
+priority than all other assignments, except another `override'.
+Subsequent assignments or appends to this variable which are not marked
+`override' will be ignored.
+
+   The `override' directive was not invented for escalation in the war
+between makefiles and command arguments.  It was invented so you can
+alter and add to values that the user specifies with command arguments.
+
+   For example, suppose you always want the `-g' switch when you run the
+C compiler, but you would like to allow the user to specify the other
+switches with a command argument just as usual.  You could use this
+`override' directive:
+
+     override CFLAGS += -g
+
+   You can also use `override' directives with `define' directives.
+This is done as you might expect:
+
+     override define foo =
+     bar
+     endef
+
+*Note Defining Multi-Line Variables: Multi-Line.
+
+
+File: make.info,  Node: Multi-Line,  Next: Undefine Directive,  Prev: Override Directive,  Up: Using Variables
+
+6.8 Defining Multi-Line Variables
+=================================
+
+Another way to set the value of a variable is to use the `define'
+directive.  This directive has an unusual syntax which allows newline
+characters to be included in the value, which is convenient for
+defining both canned sequences of commands (*note Defining Canned
+Recipes: Canned Recipes.), and also sections of makefile syntax to use
+with `eval' (*note Eval Function::).
+
+   The `define' directive is followed on the same line by the name of
+the variable being defined and an (optional) assignment operator, and
+nothing more.  The value to give the variable appears on the following
+lines.  The end of the value is marked by a line containing just the
+word `endef'.  Aside from this difference in syntax, `define' works
+just like any other variable definition.  The variable name may contain
+function and variable references, which are expanded when the directive
+is read to find the actual variable name to use.
+
+   You may omit the variable assignment operator if you prefer.  If
+omitted, `make' assumes it to be `=' and creates a recursively-expanded
+variable (*note The Two Flavors of Variables: Flavors.).  When using a
+`+=' operator, the value is appended to the previous value as with any
+other append operation: with a single space separating the old and new
+values.
+
+   You may nest `define' directives: `make' will keep track of nested
+directives and report an error if they are not all properly closed with
+`endef'.  Note that lines beginning with the recipe prefix character
+are considered part of a recipe, so any `define' or `endef' strings
+appearing on such a line will not be considered `make' directives.
+
+     define two-lines =
+     echo foo
+     echo $(bar)
+     endef
+
+   The value in an ordinary assignment cannot contain a newline; but the
+newlines that separate the lines of the value in a `define' become part
+of the variable's value (except for the final newline which precedes
+the `endef' and is not considered part of the value).
+
+   When used in a recipe, the previous example is functionally
+equivalent to this:
+
+     two-lines = echo foo; echo $(bar)
+
+since two commands separated by semicolon behave much like two separate
+shell commands.  However, note that using two separate lines means
+`make' will invoke the shell twice, running an independent subshell for
+each line.  *Note Recipe Execution: Execution.
+
+   If you want variable definitions made with `define' to take
+precedence over command-line variable definitions, you can use the
+`override' directive together with `define':
+
+     override define two-lines =
+     foo
+     $(bar)
+     endef
+
+*Note The `override' Directive: Override Directive.

+
+6.9 Undefining Variables
+========================
+
+If you want to clear a variable, setting its value to empty is usually
+sufficient. Expanding such a variable will yield the same result (empty
+string) regardless of whether it was set or not. However, if you are
+using the `flavor' (*note Flavor Function::) and `origin' (*note Origin
+Function::) functions, there is a difference between a variable that
+was never set and a variable with an empty value.  In such situations
+you may want to use the `undefine' directive to make a variable appear
+as if it was never set. For example:
+
+     foo := foo
+     bar = bar
+
+     undefine foo
+     undefine bar
+
+     $(info $(origin foo))
+     $(info $(flavor bar))
+
+   This example will print "undefined" for both variables.
+
+   If you want to undefine a command-line variable definition, you can
+use the `override' directive together with `undefine', similar to how
+this is done for variable definitions:
+
+     override undefine CFLAGS
+
+
+File: make.info,  Node: Environment,  Next: Target-specific,  Prev: Undefine Directive,  Up: Using Variables
+
+6.10 Variables from the Environment
+===================================
+
+Variables in `make' can come from the environment in which `make' is
+run.  Every environment variable that `make' sees when it starts up is
+transformed into a `make' variable with the same name and value.
+However, an explicit assignment in the makefile, or with a command
+argument, overrides the environment.  (If the `-e' flag is specified,
+then values from the environment override assignments in the makefile.
+*Note Summary of Options: Options Summary.  But this is not recommended
+practice.)
+
+   Thus, by setting the variable `CFLAGS' in your environment, you can
+cause all C compilations in most makefiles to use the compiler switches
+you prefer.  This is safe for variables with standard or conventional
+meanings because you know that no makefile will use them for other
+things.  (Note this is not totally reliable; some makefiles set
+`CFLAGS' explicitly and therefore are not affected by the value in the
+environment.)
+
+   When `make' runs a recipe, variables defined in the makefile are
+placed into the environment of each shell.  This allows you to pass
+values to sub-`make' invocations (*note Recursive Use of `make':
+Recursion.).  By default, only variables that came from the environment
+or the command line are passed to recursive invocations.  You can use
+the `export' directive to pass other variables.  *Note Communicating
+Variables to a Sub-`make': Variables/Recursion, for full details.
+
+   Other use of variables from the environment is not recommended.  It
+is not wise for makefiles to depend for their functioning on
+environment variables set up outside their control, since this would
+cause different users to get different results from the same makefile.
+This is against the whole purpose of most makefiles.
+
+   Such problems would be especially likely with the variable `SHELL',
+which is normally present in the environment to specify the user's
+choice of interactive shell.  It would be very undesirable for this
+choice to affect `make'; so, `make' handles the `SHELL' environment
+variable in a special way; see *note Choosing the Shell::.

+
+6.11 Target-specific Variable Values
+====================================
+
+Variable values in `make' are usually global; that is, they are the
+same regardless of where they are evaluated (unless they're reset, of
+course).  One exception to that is automatic variables (*note Automatic
+Variables::).
+
+   The other exception is "target-specific variable values".  This
+feature allows you to define different values for the same variable,
+based on the target that `make' is currently building.  As with
+automatic variables, these values are only available within the context
+of a target's recipe (and in other target-specific assignments).
+
+   Set a target-specific variable value like this:
+
+     TARGET ... : VARIABLE-ASSIGNMENT
+
+   Target-specific variable assignments can be prefixed with any or all
+of the special keywords `export', `override', or `private'; these apply
+their normal behavior to this instance of the variable only.
+
+   Multiple TARGET values create a target-specific variable value for
+each member of the target list individually.
+
+   The VARIABLE-ASSIGNMENT can be any valid form of assignment;
+recursive (`='), static (`:='), appending (`+='), or conditional
+(`?=').  All variables that appear within the VARIABLE-ASSIGNMENT are
+evaluated within the context of the target: thus, any
+previously-defined target-specific variable values will be in effect.
+Note that this variable is actually distinct from any "global" value:
+the two variables do not have to have the same flavor (recursive vs.
+static).
+
+   Target-specific variables have the same priority as any other
+makefile variable.  Variables provided on the command line (and in the
+environment if the `-e' option is in force) will take precedence.
+Specifying the `override' directive will allow the target-specific
+variable value to be preferred.
+
+   There is one more special feature of target-specific variables: when
+you define a target-specific variable that variable value is also in
+effect for all prerequisites of this target, and all their
+prerequisites, etc. (unless those prerequisites override that variable
+with their own target-specific variable value).  So, for example, a
+statement like this:
+
+     prog : CFLAGS = -g
+     prog : prog.o foo.o bar.o
+
+will set `CFLAGS' to `-g' in the recipe for `prog', but it will also
+set `CFLAGS' to `-g' in the recipes that create `prog.o', `foo.o', and
+`bar.o', and any recipes which create their prerequisites.
+
+   Be aware that a given prerequisite will only be built once per
+invocation of make, at most.  If the same file is a prerequisite of
+multiple targets, and each of those targets has a different value for
+the same target-specific variable, then the first target to be built
+will cause that prerequisite to be built and the prerequisite will
+inherit the target-specific value from the first target.  It will
+ignore the target-specific values from any other targets.
+
+
+File: make.info,  Node: Pattern-specific,  Next: Suppressing Inheritance,  Prev: Target-specific,  Up: Using Variables
+
+6.12 Pattern-specific Variable Values
+=====================================
+
+In addition to target-specific variable values (*note Target-specific
+Variable Values: Target-specific.), GNU `make' supports
+pattern-specific variable values.  In this form, the variable is
+defined for any target that matches the pattern specified.
+
+   Set a pattern-specific variable value like this:
+
+     PATTERN ... : VARIABLE-ASSIGNMENT
+   where PATTERN is a %-pattern.  As with target-specific variable
+values, multiple PATTERN values create a pattern-specific variable
+value for each pattern individually.  The VARIABLE-ASSIGNMENT can be
+any valid form of assignment.  Any command line variable setting will
+take precedence, unless `override' is specified.
+
+   For example:
+
+     %.o : CFLAGS = -O
+
+will assign `CFLAGS' the value of `-O' for all targets matching the
+pattern `%.o'.
+
+   If a target matches more than one pattern, the matching
+pattern-specific variables with longer stems are interpreted first.
+This results in more specific variables taking precedence over the more
+generic ones, for example:
+
+     %.o: %.c
+             $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@
+
+     lib/%.o: CFLAGS := -fPIC -g
+     %.o: CFLAGS := -g
+
+     all: foo.o lib/bar.o
+
+   In this example the first definition of the `CFLAGS' variable will
+be used to update `lib/bar.o' even though the second one also applies
+to this target. Pattern-specific variables which result in the same
+stem length are considered in the order in which they were defined in
+the makefile.
+
+   Pattern-specific variables are searched after any target-specific
+variables defined explicitly for that target, and before target-specific
+variables defined for the parent target.
+

+File: make.info,  Node: Suppressing Inheritance,  Next: Special Variables,  Prev: Pattern-specific,  Up: Using Variables
+
+6.13 Suppressing Inheritance
+============================
+
+As described in previous sections, `make' variables are inherited by
+prerequisites.  This capability allows you to modify the behavior of a
+prerequisite based on which targets caused it to be rebuilt.  For
+example, you might set a target-specific variable on a `debug' target,
+then running `make debug' will cause that variable to be inherited by
+all prerequisites of `debug', while just running `make all' (for
+example) would not have that assignment.
+
+   Sometimes, however, you may not want a variable to be inherited.  For
+these situations, `make' provides the `private' modifier.  Although
+this modifier can be used with any variable assignment, it makes the
+most sense with target- and pattern-specific variables.  Any variable
+marked `private' will be visible to its local target but will not be
+inherited by prerequisites of that target.  A global variable marked
+`private' will be visible in the global scope but will not be inherited
+by any target, and hence will not be visible in any recipe.
+
+   As an example, consider this makefile:
+     EXTRA_CFLAGS =
+
+     prog: private EXTRA_CFLAGS = -L/usr/local/lib
+     prog: a.o b.o
+
+   Due to the `private' modifier, `a.o' and `b.o' will not inherit the
+`EXTRA_CFLAGS' variable assignment from the `progs' target.
+
+
+File: make.info,  Node: Special Variables,  Prev: Suppressing Inheritance,  Up: Using Variables
+
+6.14 Other Special Variables
+============================
+
+GNU `make' supports some variables that have special properties.
+
+`MAKEFILE_LIST'
+     Contains the name of each makefile that is parsed by `make', in
+     the order in which it was parsed.  The name is appended just
+     before `make' begins to parse the makefile.  Thus, if the first
+     thing a makefile does is examine the last word in this variable, it
+     will be the name of the current makefile.  Once the current
+     makefile has used `include', however, the last word will be the
+     just-included makefile.
+
+     If a makefile named `Makefile' has this content:
+
+          name1 := $(lastword $(MAKEFILE_LIST))
+
+          include inc.mk
+
+          name2 := $(lastword $(MAKEFILE_LIST))
+
+          all:
+                  @echo name1 = $(name1)
+                  @echo name2 = $(name2)
+
+     then you would expect to see this output:
+
+          name1 = Makefile
+          name2 = inc.mk
+
+`.DEFAULT_GOAL'
+     Sets the default goal to be used if no targets were specified on
+     the command line (*note Arguments to Specify the Goals: Goals.).
+     The `.DEFAULT_GOAL' variable allows you to discover the current
+     default goal, restart the default goal selection algorithm by
+     clearing its value, or to explicitly set the default goal.  The
+     following example illustrates these cases:
+
+          # Query the default goal.
+          ifeq ($(.DEFAULT_GOAL),)
+            $(warning no default goal is set)
+          endif
+
+          .PHONY: foo
+          foo: ; @echo $@
+
+          $(warning default goal is $(.DEFAULT_GOAL))
+
+          # Reset the default goal.
+          .DEFAULT_GOAL :=
+
+          .PHONY: bar
+          bar: ; @echo $@
+
+          $(warning default goal is $(.DEFAULT_GOAL))
+
+          # Set our own.
+          .DEFAULT_GOAL := foo
+
+     This makefile prints:
+
+          no default goal is set
+          default goal is foo
+          default goal is bar
+          foo
+
+     Note that assigning more than one target name to `.DEFAULT_GOAL' is
+     illegal and will result in an error.
+
+`MAKE_RESTARTS'
+     This variable is set only if this instance of `make' has restarted
+     (*note How Makefiles Are Remade: Remaking Makefiles.): it will
+     contain the number of times this instance has restarted.  Note
+     this is not the same as recursion (counted by the `MAKELEVEL'
+     variable).  You should not set, modify, or export this variable.
+
+`.RECIPEPREFIX'
+     The first character of the value of this variable is used as the
+     character make assumes is introducing a recipe line.  If the
+     variable is empty (as it is by default) that character is the
+     standard tab character.  For example, this is a valid makefile:
+
+          .RECIPEPREFIX = >
+          all:
+          > @echo Hello, world
+
+     The value of `.RECIPEPREFIX' can be changed multiple times; once
+     set it stays in effect for all rules parsed until it is modified.
+
+`.VARIABLES'
+     Expands to a list of the _names_ of all global variables defined
+     so far.  This includes variables which have empty values, as well
+     as built-in variables (*note Variables Used by Implicit Rules:
+     Implicit Variables.), but does not include any variables which are
+     only defined in a target-specific context.  Note that any value
+     you assign to this variable will be ignored; it will always return
+     its special value.
+
+`.FEATURES'
+     Expands to a list of special features supported by this version of
+     `make'.  Possible values include:
+
+    `archives'
+          Supports `ar' (archive) files using special filename syntax.
+          *Note Using `make' to Update Archive Files: Archives.
+
+    `check-symlink'
+          Supports the `-L' (`--check-symlink-times') flag.  *Note
+          Summary of Options: Options Summary.
+

+7 Conditional Parts of Makefiles
+********************************
+
+A "conditional" directive causes part of a makefile to be obeyed or
+ignored depending on the values of variables.  Conditionals can compare
+the value of one variable to another, or the value of a variable to a
+constant string.  Conditionals control what `make' actually "sees" in
+the makefile, so they _cannot_ be used to control recipes at the time
+of execution.

+
+7.1 Example of a Conditional
+============================
+
+The following example of a conditional tells `make' to use one set of
+libraries if the `CC' variable is `gcc', and a different set of
+libraries otherwise.  It works by controlling which of two recipe lines
+will be used for the rule.  The result is that `CC=gcc' as an argument
+to `make' changes not only which compiler is used but also which
+libraries are linked.
+
+     libs_for_gcc = -lgnu
+     normal_libs =
+
+     foo: $(objects)
+     ifeq ($(CC),gcc)
+             $(CC) -o foo $(objects) $(libs_for_gcc)
+     else
+             $(CC) -o foo $(objects) $(normal_libs)
+     endif
+
+   This conditional uses three directives: one `ifeq', one `else' and
+one `endif'.
+
+   The `ifeq' directive begins the conditional, and specifies the
+condition.  It contains two arguments, separated by a comma and
+surrounded by parentheses.  Variable substitution is performed on both
+arguments and then they are compared.  The lines of the makefile
+following the `ifeq' are obeyed if the two arguments match; otherwise
+they are ignored.
+
+   The `else' directive causes the following lines to be obeyed if the
+previous conditional failed.  In the example above, this means that the
+second alternative linking command is used whenever the first
+alternative is not used.  It is optional to have an `else' in a
+conditional.
+
+   The `endif' directive ends the conditional.  Every conditional must
+end with an `endif'.  Unconditional makefile text follows.
+
+   As this example illustrates, conditionals work at the textual level:
+the lines of the conditional are treated as part of the makefile, or
+ignored, according to the condition.  This is why the larger syntactic
+units of the makefile, such as rules, may cross the beginning or the
+end of the conditional.
+
+   When the variable `CC' has the value `gcc', the above example has
+this effect:
+
+     foo: $(objects)
+             $(CC) -o foo $(objects) $(libs_for_gcc)
+
+When the variable `CC' has any other value, the effect is this:
+
+     foo: $(objects)
+             $(CC) -o foo $(objects) $(normal_libs)
+
+   Equivalent results can be obtained in another way by
+conditionalizing a variable assignment and then using the variable
+unconditionally:
+
+     libs_for_gcc = -lgnu
+     normal_libs =
+
+     ifeq ($(CC),gcc)
+       libs=$(libs_for_gcc)
+     else
+       libs=$(normal_libs)
+     endif
+
+     foo: $(objects)
+             $(CC) -o foo $(objects) $(libs)

+
+7.2 Syntax of Conditionals
+==========================
+
+The syntax of a simple conditional with no `else' is as follows:
+
+     CONDITIONAL-DIRECTIVE
+     TEXT-IF-TRUE
+     endif
+
+The TEXT-IF-TRUE may be any lines of text, to be considered as part of
+the makefile if the condition is true.  If the condition is false, no
+text is used instead.
+
+   The syntax of a complex conditional is as follows:
+
+     CONDITIONAL-DIRECTIVE
+     TEXT-IF-TRUE
+     else
+     TEXT-IF-FALSE
+     endif
+
+   or:
+
+     CONDITIONAL-DIRECTIVE
+     TEXT-IF-ONE-IS-TRUE
+     else CONDITIONAL-DIRECTIVE
+     TEXT-IF-TRUE
+     else
+     TEXT-IF-FALSE
+     endif
+
+There can be as many "`else' CONDITIONAL-DIRECTIVE" clauses as
+necessary.  Once a given condition is true, TEXT-IF-TRUE is used and no
+other clause is used; if no condition is true then TEXT-IF-FALSE is
+used.  The TEXT-IF-TRUE and TEXT-IF-FALSE can be any number of lines of
+text.
+
+   The syntax of the CONDITIONAL-DIRECTIVE is the same whether the
+conditional is simple or complex; after an `else' or not.  There are
+four different directives that test different conditions.  Here is a
+table of them:
+
+`ifeq (ARG1, ARG2)'
+`ifeq 'ARG1' 'ARG2''
+`ifeq "ARG1" "ARG2"'
+`ifeq "ARG1" 'ARG2''
+`ifeq 'ARG1' "ARG2"'
+     Expand all variable references in ARG1 and ARG2 and compare them.
+     If they are identical, the TEXT-IF-TRUE is effective; otherwise,
+     the TEXT-IF-FALSE, if any, is effective.
+
+     Often you want to test if a variable has a non-empty value.  When
+     the value results from complex expansions of variables and
+     functions, expansions you would consider empty may actually
+     contain whitespace characters and thus are not seen as empty.
+     However, you can use the `strip' function (*note Text Functions::)
+     to avoid interpreting whitespace as a non-empty value.  For
+     example:
+
+          ifeq ($(strip $(foo)),)
+          TEXT-IF-EMPTY
+          endif
+
+     will evaluate TEXT-IF-EMPTY even if the expansion of `$(foo)'
+     contains whitespace characters.
+
+`ifneq (ARG1, ARG2)'
+`ifneq 'ARG1' 'ARG2''
+`ifneq "ARG1" "ARG2"'
+`ifneq "ARG1" 'ARG2''
+`ifneq 'ARG1' "ARG2"'
+     Expand all variable references in ARG1 and ARG2 and compare them.
+     If they are different, the TEXT-IF-TRUE is effective; otherwise,
+     the TEXT-IF-FALSE, if any, is effective.
+
+`ifdef VARIABLE-NAME'
+     The `ifdef' form takes the _name_ of a variable as its argument,
+     not a reference to a variable.  The value of that variable has a
+     non-empty value, the TEXT-IF-TRUE is effective; otherwise, the
+     TEXT-IF-FALSE, if any, is effective.  Variables that have never
+     been defined have an empty value.  The text VARIABLE-NAME is
+     expanded, so it could be a variable or function that expands to
+     the name of a variable.  For example:
+
+          bar = true
+          foo = bar
+          ifdef $(foo)
+          frobozz = yes
+          endif
+
+     The variable reference `$(foo)' is expanded, yielding `bar', which
+     is considered to be the name of a variable.  The variable `bar' is
+     not expanded, but its value is examined to determine if it is
+     non-empty.
+
+     Note that `ifdef' only tests whether a variable has a value.  It
+     does not expand the variable to see if that value is nonempty.
+     Consequently, tests using `ifdef' return true for all definitions
+     except those like `foo ='.  To test for an empty value, use
+     `ifeq ($(foo),)'.  For example,
+
+          bar =
+          foo = $(bar)
+          ifdef foo
+          frobozz = yes
+          else
+          frobozz = no
+          endif
+
+     sets `frobozz' to `yes', while:
+
+          foo =
+          ifdef foo
+          frobozz = yes
+          else
+          frobozz = no
+          endif
+
+     sets `frobozz' to `no'.
+
+`ifndef VARIABLE-NAME'
+     If the variable VARIABLE-NAME has an empty value, the TEXT-IF-TRUE
+     is effective; otherwise, the TEXT-IF-FALSE, if any, is effective.
+     The rules for expansion and testing of VARIABLE-NAME are identical
+     to the `ifdef' directive.
+
+   Extra spaces are allowed and ignored at the beginning of the
+conditional directive line, but a tab is not allowed.  (If the line
+begins with a tab, it will be considered part of a recipe for a rule.)
+Aside from this, extra spaces or tabs may be inserted with no effect
+anywhere except within the directive name or within an argument.  A
+comment starting with `#' may appear at the end of the line.
+
+   The other two directives that play a part in a conditional are `else'
+and `endif'.  Each of these directives is written as one word, with no
+arguments.  Extra spaces are allowed and ignored at the beginning of the
+line, and spaces or tabs at the end.  A comment starting with `#' may
+appear at the end of the line.
+
+   Conditionals affect which lines of the makefile `make' uses.  If the
+condition is true, `make' reads the lines of the TEXT-IF-TRUE as part
+of the makefile; if the condition is false, `make' ignores those lines
+completely.  It follows that syntactic units of the makefile, such as
+rules, may safely be split across the beginning or the end of the
+conditional.
+
+   `make' evaluates conditionals when it reads a makefile.
+Consequently, you cannot use automatic variables in the tests of
+conditionals because they are not defined until recipes are run (*note
+Automatic Variables::).
+
+   To prevent intolerable confusion, it is not permitted to start a
+conditional in one makefile and end it in another.  However, you may
+write an `include' directive within a conditional, provided you do not
+attempt to terminate the conditional inside the included file.

+
+7.3 Conditionals that Test Flags
+================================
+
+You can write a conditional that tests `make' command flags such as
+`-t' by using the variable `MAKEFLAGS' together with the `findstring'
+function (*note Functions for String Substitution and Analysis: Text
+Functions.).  This is useful when `touch' is not enough to make a file
+appear up to date.
+
+   The `findstring' function determines whether one string appears as a
+substring of another.  If you want to test for the `-t' flag, use `t'
+as the first string and the value of `MAKEFLAGS' as the other.
+
+   For example, here is how to arrange to use `ranlib -t' to finish
+marking an archive file up to date:
+
+     archive.a: ...
+     ifneq (,$(findstring t,$(MAKEFLAGS)))
+             +touch archive.a
+             +ranlib -t archive.a
+     else
+             ranlib archive.a
+     endif
+
+The `+' prefix marks those recipe lines as "recursive" so that they
+will be executed despite use of the `-t' flag.  *Note Recursive Use of
+`make': Recursion.

+8 Functions for Transforming Text
+*********************************
+
+"Functions" allow you to do text processing in the makefile to compute
+the files to operate on or the commands to use in recipes.  You use a
+function in a "function call", where you give the name of the function
+and some text (the "arguments") for the function to operate on.  The
+result of the function's processing is substituted into the makefile at
+the point of the call, just as a variable might be substituted.

+
+8.1 Function Call Syntax
+========================
+
+A function call resembles a variable reference.  It looks like this:
+
+     $(FUNCTION ARGUMENTS)
+
+or like this:
+
+     ${FUNCTION ARGUMENTS}
+
+   Here FUNCTION is a function name; one of a short list of names that
+are part of `make'.  You can also essentially create your own functions
+by using the `call' builtin function.
+
+   The ARGUMENTS are the arguments of the function.  They are separated
+from the function name by one or more spaces or tabs, and if there is
+more than one argument, then they are separated by commas.  Such
+whitespace and commas are not part of an argument's value.  The
+delimiters which you use to surround the function call, whether
+parentheses or braces, can appear in an argument only in matching pairs;
+the other kind of delimiters may appear singly.  If the arguments
+themselves contain other function calls or variable references, it is
+wisest to use the same kind of delimiters for all the references; write
+`$(subst a,b,$(x))', not `$(subst a,b,${x})'.  This is because it is
+clearer, and because only one type of delimiter is matched to find the
+end of the reference.
+
+   The text written for each argument is processed by substitution of
+variables and function calls to produce the argument value, which is
+the text on which the function acts.  The substitution is done in the
+order in which the arguments appear.
+
+   Commas and unmatched parentheses or braces cannot appear in the text
+of an argument as written; leading spaces cannot appear in the text of
+the first argument as written.  These characters can be put into the
+argument value by variable substitution.  First define variables
+`comma' and `space' whose values are isolated comma and space
+characters, then substitute these variables where such characters are
+wanted, like this:
+
+     comma:= ,
+     empty:=
+     space:= $(empty) $(empty)
+     foo:= a b c
+     bar:= $(subst $(space),$(comma),$(foo))
+     # bar is now `a,b,c'.
+
+Here the `subst' function replaces each space with a comma, through the
+value of `foo', and substitutes the result.

+
+8.2 Functions for String Substitution and Analysis
+==================================================
+
+Here are some functions that operate on strings:
+
+`$(subst FROM,TO,TEXT)'
+     Performs a textual replacement on the text TEXT: each occurrence
+     of FROM is replaced by TO.  The result is substituted for the
+     function call.  For example,
+
+          $(subst ee,EE,feet on the street)
+
+     substitutes the string `fEEt on the strEEt'.
+
+`$(patsubst PATTERN,REPLACEMENT,TEXT)'
+     Finds whitespace-separated words in TEXT that match PATTERN and
+     replaces them with REPLACEMENT.  Here PATTERN may contain a `%'
+     which acts as a wildcard, matching any number of any characters
+     within a word.  If REPLACEMENT also contains a `%', the `%' is
+     replaced by the text that matched the `%' in PATTERN.  Only the
+     first `%' in the PATTERN and REPLACEMENT is treated this way; any
+     subsequent `%' is unchanged.
+
+     `%' characters in `patsubst' function invocations can be quoted
+     with preceding backslashes (`\').  Backslashes that would
+     otherwise quote `%' characters can be quoted with more backslashes.
+     Backslashes that quote `%' characters or other backslashes are
+     removed from the pattern before it is compared file names or has a
+     stem substituted into it.  Backslashes that are not in danger of
+     quoting `%' characters go unmolested.  For example, the pattern
+     `the\%weird\\%pattern\\' has `the%weird\' preceding the operative
+     `%' character, and `pattern\\' following it.  The final two
+     backslashes are left alone because they cannot affect any `%'
+     character.
+
+     Whitespace between words is folded into single space characters;
+     leading and trailing whitespace is discarded.
+
+     For example,
+
+          $(patsubst %.c,%.o,x.c.c bar.c)
+
+     produces the value `x.c.o bar.o'.
+
+     Substitution references (*note Substitution References:
+     Substitution Refs.) are a simpler way to get the effect of the
+     `patsubst' function:
+
+          $(VAR:PATTERN=REPLACEMENT)
+
+     is equivalent to
+
+          $(patsubst PATTERN,REPLACEMENT,$(VAR))
+
+     The second shorthand simplifies one of the most common uses of
+     `patsubst': replacing the suffix at the end of file names.
+
+          $(VAR:SUFFIX=REPLACEMENT)
+
+     is equivalent to
+
+          $(patsubst %SUFFIX,%REPLACEMENT,$(VAR))
+
+     For example, you might have a list of object files:
+
+          objects = foo.o bar.o baz.o
+
+     To get the list of corresponding source files, you could simply
+     write:
+
+          $(objects:.o=.c)
+
+     instead of using the general form:
+
+          $(patsubst %.o,%.c,$(objects))
+
+`$(strip STRING)'
+     Removes leading and trailing whitespace from STRING and replaces
+     each internal sequence of one or more whitespace characters with a
+     single space.  Thus, `$(strip a b  c )' results in `a b c'.
+
+     The function `strip' can be very useful when used in conjunction
+     with conditionals.  When comparing something with the empty string
+     `' using `ifeq' or `ifneq', you usually want a string of just
+     whitespace to match the empty string (*note Conditionals::).
+
+     Thus, the following may fail to have the desired results:
+
+          .PHONY: all
+          ifneq   "$(needs_made)" ""
+          all: $(needs_made)
+          else
+          all:;@echo 'Nothing to make!'
+          endif
+
+     Replacing the variable reference `$(needs_made)' with the function
+     call `$(strip $(needs_made))' in the `ifneq' directive would make
+     it more robust.
+
+`$(findstring FIND,IN)'
+     Searches IN for an occurrence of FIND.  If it occurs, the value is
+     FIND; otherwise, the value is empty.  You can use this function in
+     a conditional to test for the presence of a specific substring in
+     a given string.  Thus, the two examples,
+
+          $(findstring a,a b c)
+          $(findstring a,b c)
+
+     produce the values `a' and `' (the empty string), respectively.
+     *Note Testing Flags::, for a practical application of `findstring'.
+
+`$(filter PATTERN...,TEXT)'
+     Returns all whitespace-separated words in TEXT that _do_ match any
+     of the PATTERN words, removing any words that _do not_ match.  The
+     patterns are written using `%', just like the patterns used in the
+     `patsubst' function above.
+
+     The `filter' function can be used to separate out different types
+     of strings (such as file names) in a variable.  For example:
+
+          sources := foo.c bar.c baz.s ugh.h
+          foo: $(sources)
+                  cc $(filter %.c %.s,$(sources)) -o foo
+
+     says that `foo' depends of `foo.c', `bar.c', `baz.s' and `ugh.h'
+     but only `foo.c', `bar.c' and `baz.s' should be specified in the
+     command to the compiler.
+
+`$(filter-out PATTERN...,TEXT)'
+     Returns all whitespace-separated words in TEXT that _do not_ match
+     any of the PATTERN words, removing the words that _do_ match one
+     or more.  This is the exact opposite of the `filter' function.
+
+     For example, given:
+
+          objects=main1.o foo.o main2.o bar.o
+          mains=main1.o main2.o
+
+     the following generates a list which contains all the object files
+     not in `mains':
+
+          $(filter-out $(mains),$(objects))
+
+`$(sort LIST)'
+     Sorts the words of LIST in lexical order, removing duplicate
+     words.  The output is a list of words separated by single spaces.
+     Thus,
+
+          $(sort foo bar lose)
+
+     returns the value `bar foo lose'.
+
+     Incidentally, since `sort' removes duplicate words, you can use it
+     for this purpose even if you don't care about the sort order.
+
+`$(word N,TEXT)'
+     Returns the Nth word of TEXT.  The legitimate values of N start
+     from 1.  If N is bigger than the number of words in TEXT, the
+     value is empty.  For example,
+
+          $(word 2, foo bar baz)
+
+     returns `bar'.
+
+`$(wordlist S,E,TEXT)'
+     Returns the list of words in TEXT starting with word S and ending
+     with word E (inclusive).  The legitimate values of S start from 1;
+     E may start from 0.  If S is bigger than the number of words in
+     TEXT, the value is empty.  If E is bigger than the number of words
+     in TEXT, words up to the end of TEXT are returned.  If S is
+     greater than E, nothing is returned.  For example,
+
+          $(wordlist 2, 3, foo bar baz)
+
+     returns `bar baz'.
+
+`$(words TEXT)'
+     Returns the number of words in TEXT.  Thus, the last word of TEXT
+     is `$(word $(words TEXT),TEXT)'.
+
+`$(firstword NAMES...)'
+     The argument NAMES is regarded as a series of names, separated by
+     whitespace.  The value is the first name in the series.  The rest
+     of the names are ignored.
+
+     For example,
+
+          $(firstword foo bar)
+
+     produces the result `foo'.  Although `$(firstword TEXT)' is the
+     same as `$(word 1,TEXT)', the `firstword' function is retained for
+     its simplicity.
+
+`$(lastword NAMES...)'
+     The argument NAMES is regarded as a series of names, separated by
+     whitespace.  The value is the last name in the series.
+
+     For example,
+
+          $(lastword foo bar)
+
+     produces the result `bar'.  Although `$(lastword TEXT)' is the
+     same as `$(word $(words TEXT),TEXT)', the `lastword' function was
+     added for its simplicity and better performance.
+
+   Here is a realistic example of the use of `subst' and `patsubst'.
+Suppose that a makefile uses the `VPATH' variable to specify a list of
+directories that `make' should search for prerequisite files (*note
+`VPATH' Search Path for All Prerequisites: General Search.).  This
+example shows how to tell the C compiler to search for header files in
+the same list of directories.
+
+   The value of `VPATH' is a list of directories separated by colons,
+such as `src:../headers'.  First, the `subst' function is used to
+change the colons to spaces:
+
+     $(subst :, ,$(VPATH))
+
+This produces `src ../headers'.  Then `patsubst' is used to turn each
+directory name into a `-I' flag.  These can be added to the value of
+the variable `CFLAGS', which is passed automatically to the C compiler,
+like this:
+
+     override CFLAGS += $(patsubst %,-I%,$(subst :, ,$(VPATH)))
+
+The effect is to append the text `-Isrc -I../headers' to the previously
+given value of `CFLAGS'.  The `override' directive is used so that the
+new value is assigned even if the previous value of `CFLAGS' was
+specified with a command argument (*note The `override' Directive:
+Override Directive.).

+8.3 Functions for File Names
+============================
+
+Several of the built-in expansion functions relate specifically to
+taking apart file names or lists of file names.
+
+   Each of the following functions performs a specific transformation
+on a file name.  The argument of the function is regarded as a series
+of file names, separated by whitespace.  (Leading and trailing
+whitespace is ignored.)  Each file name in the series is transformed in
+the same way and the results are concatenated with single spaces
+between them.
+
+`$(dir NAMES...)'
+     Extracts the directory-part of each file name in NAMES.  The
+     directory-part of the file name is everything up through (and
+     including) the last slash in it.  If the file name contains no
+     slash, the directory part is the string `./'.  For example,
+
+          $(dir src/foo.c hacks)
+
+     produces the result `src/ ./'.
+
+`$(notdir NAMES...)'
+     Extracts all but the directory-part of each file name in NAMES.
+     If the file name contains no slash, it is left unchanged.
+     Otherwise, everything through the last slash is removed from it.
+
+     A file name that ends with a slash becomes an empty string.  This
+     is unfortunate, because it means that the result does not always
+     have the same number of whitespace-separated file names as the
+     argument had; but we do not see any other valid alternative.
+
+     For example,
+
+          $(notdir src/foo.c hacks)
+
+     produces the result `foo.c hacks'.
+
+`$(suffix NAMES...)'
+     Extracts the suffix of each file name in NAMES.  If the file name
+     contains a period, the suffix is everything starting with the last
+     period.  Otherwise, the suffix is the empty string.  This
+     frequently means that the result will be empty when NAMES is not,
+     and if NAMES contains multiple file names, the result may contain
+     fewer file names.
+
+     For example,
+
+          $(suffix src/foo.c src-1.0/bar.c hacks)
+
+     produces the result `.c .c'.
+
+`$(basename NAMES...)'
+     Extracts all but the suffix of each file name in NAMES.  If the
+     file name contains a period, the basename is everything starting
+     up to (and not including) the last period.  Periods in the
+     directory part are ignored.  If there is no period, the basename
+     is the entire file name.  For example,
+
+          $(basename src/foo.c src-1.0/bar hacks)
+
+     produces the result `src/foo src-1.0/bar hacks'.
+
+`$(addsuffix SUFFIX,NAMES...)'
+     The argument NAMES is regarded as a series of names, separated by
+     whitespace; SUFFIX is used as a unit.  The value of SUFFIX is
+     appended to the end of each individual name and the resulting
+     larger names are concatenated with single spaces between them.
+     For example,
+
+          $(addsuffix .c,foo bar)
+
+     produces the result `foo.c bar.c'.
+
+`$(addprefix PREFIX,NAMES...)'
+     The argument NAMES is regarded as a series of names, separated by
+     whitespace; PREFIX is used as a unit.  The value of PREFIX is
+     prepended to the front of each individual name and the resulting
+     larger names are concatenated with single spaces between them.
+     For example,
+
+          $(addprefix src/,foo bar)
+
+     produces the result `src/foo src/bar'.
+
+`$(join LIST1,LIST2)'
+     Concatenates the two arguments word by word: the two first words
+     (one from each argument) concatenated form the first word of the
+     result, the two second words form the second word of the result,
+     and so on.  So the Nth word of the result comes from the Nth word
+     of each argument.  If one argument has more words that the other,
+     the extra words are copied unchanged into the result.
+
+     For example, `$(join a b,.c .o)' produces `a.c b.o'.
+
+     Whitespace between the words in the lists is not preserved; it is
+     replaced with a single space.
+
+     This function can merge the results of the `dir' and `notdir'
+     functions, to produce the original list of files which was given
+     to those two functions.
+
+`$(wildcard PATTERN)'
+     The argument PATTERN is a file name pattern, typically containing
+     wildcard characters (as in shell file name patterns).  The result
+     of `wildcard' is a space-separated list of the names of existing
+     files that match the pattern.  *Note Using Wildcard Characters in
+     File Names: Wildcards.
+
+`$(realpath NAMES...)'
+     For each file name in NAMES return the canonical absolute name.  A
+     canonical name does not contain any `.' or `..' components, nor
+     any repeated path separators (`/') or symlinks.  In case of a
+     failure the empty string is returned.  Consult the `realpath(3)'
+     documentation for a list of possible failure causes.
+
+`$(abspath NAMES...)'
+     For each file name in NAMES return an absolute name that does not
+     contain any `.' or `..' components, nor any repeated path
+     separators (`/').  Note that, in contrast to `realpath' function,
+     `abspath' does not resolve symlinks and does not require the file
+     names to refer to an existing file or directory.  Use the
+     `wildcard' function to test for existence.

+
+8.4 Functions for Conditionals
+==============================
+
+There are three functions that provide conditional expansion.  A key
+aspect of these functions is that not all of the arguments are expanded
+initially.  Only those arguments which need to be expanded, will be
+expanded.
+
+`$(if CONDITION,THEN-PART[,ELSE-PART])'
+     The `if' function provides support for conditional expansion in a
+     functional context (as opposed to the GNU `make' makefile
+     conditionals such as `ifeq' (*note Syntax of Conditionals:
+     Conditional Syntax.).
+
+     The first argument, CONDITION, first has all preceding and
+     trailing whitespace stripped, then is expanded.  If it expands to
+     any non-empty string, then the condition is considered to be true.
+     If it expands to an empty string, the condition is considered to
+     be false.
+
+     If the condition is true then the second argument, THEN-PART, is
+     evaluated and this is used as the result of the evaluation of the
+     entire `if' function.
+
+     If the condition is false then the third argument, ELSE-PART, is
+     evaluated and this is the result of the `if' function.  If there is
+     no third argument, the `if' function evaluates to nothing (the
+     empty string).
+
+     Note that only one of the THEN-PART or the ELSE-PART will be
+     evaluated, never both.  Thus, either can contain side-effects
+     (such as `shell' function calls, etc.)
+
+`$(or CONDITION1[,CONDITION2[,CONDITION3...]])'
+     The `or' function provides a "short-circuiting" OR operation.
+     Each argument is expanded, in order.  If an argument expands to a
+     non-empty string the processing stops and the result of the
+     expansion is that string.  If, after all arguments are expanded,
+     all of them are false (empty), then the result of the expansion is
+     the empty string.
+
+`$(and CONDITION1[,CONDITION2[,CONDITION3...]])'
+     The `and' function provides a "short-circuiting" AND operation.
+     Each argument is expanded, in order.  If an argument expands to an
+     empty string the processing stops and the result of the expansion
+     is the empty string.  If all arguments expand to a non-empty
+     string then the result of the expansion is the expansion of the
+     last argument.

+
+8.5 The `foreach' Function
+==========================
+
+The `foreach' function is very different from other functions.  It
+causes one piece of text to be used repeatedly, each time with a
+different substitution performed on it.  It resembles the `for' command
+in the shell `sh' and the `foreach' command in the C-shell `csh'.
+
+   The syntax of the `foreach' function is:
+
+     $(foreach VAR,LIST,TEXT)
+
+The first two arguments, VAR and LIST, are expanded before anything
+else is done; note that the last argument, TEXT, is *not* expanded at
+the same time.  Then for each word of the expanded value of LIST, the
+variable named by the expanded value of VAR is set to that word, and
+TEXT is expanded.  Presumably TEXT contains references to that
+variable, so its expansion will be different each time.
+
+   The result is that TEXT is expanded as many times as there are
+whitespace-separated words in LIST.  The multiple expansions of TEXT
+are concatenated, with spaces between them, to make the result of
+`foreach'.
+
+   This simple example sets the variable `files' to the list of all
+files in the directories in the list `dirs':
+
+     dirs := a b c d
+     files := $(foreach dir,$(dirs),$(wildcard $(dir)/*))
+
+   Here TEXT is `$(wildcard $(dir)/*)'.  The first repetition finds the
+value `a' for `dir', so it produces the same result as `$(wildcard
+a/*)'; the second repetition produces the result of `$(wildcard b/*)';
+and the third, that of `$(wildcard c/*)'.
+
+   This example has the same result (except for setting `dirs') as the
+following example:
+
+     files := $(wildcard a/* b/* c/* d/*)
+
+   When TEXT is complicated, you can improve readability by giving it a
+name, with an additional variable:
+
+     find_files = $(wildcard $(dir)/*)
+     dirs := a b c d
+     files := $(foreach dir,$(dirs),$(find_files))
+
+Here we use the variable `find_files' this way.  We use plain `=' to
+define a recursively-expanding variable, so that its value contains an
+actual function call to be reexpanded under the control of `foreach'; a
+simply-expanded variable would not do, since `wildcard' would be called
+only once at the time of defining `find_files'.
+
+   The `foreach' function has no permanent effect on the variable VAR;
+its value and flavor after the `foreach' function call are the same as
+they were beforehand.  The other values which are taken from LIST are
+in effect only temporarily, during the execution of `foreach'.  The
+variable VAR is a simply-expanded variable during the execution of
+`foreach'.  If VAR was undefined before the `foreach' function call, it
+is undefined after the call.  *Note The Two Flavors of Variables:
+Flavors.
+
+   You must take care when using complex variable expressions that
+result in variable names because many strange things are valid variable
+names, but are probably not what you intended.  For example,
+
+     files := $(foreach Esta escrito en espanol!,b c ch,$(find_files))
+
+might be useful if the value of `find_files' references the variable
+whose name is `Esta escrito en espanol!' (es un nombre bastante largo,
+no?), but it is more likely to be a mistake.
+
+
+File: make.info,  Node: Call Function,  Next: Value Function,  Prev: Foreach Function,  Up: Functions
+
+8.6 The `call' Function
+=======================
+
+The `call' function is unique in that it can be used to create new
+parameterized functions.  You can write a complex expression as the
+value of a variable, then use `call' to expand it with different values.
+
+   The syntax of the `call' function is:
+
+     $(call VARIABLE,PARAM,PARAM,...)
+
+   When `make' expands this function, it assigns each PARAM to
+temporary variables `$(1)', `$(2)', etc.  The variable `$(0)' will
+contain VARIABLE.  There is no maximum number of parameter arguments.
+There is no minimum, either, but it doesn't make sense to use `call'
+with no parameters.
+
+   Then VARIABLE is expanded as a `make' variable in the context of
+these temporary assignments.  Thus, any reference to `$(1)' in the
+value of VARIABLE will resolve to the first PARAM in the invocation of
+`call'.
+
+   Note that VARIABLE is the _name_ of a variable, not a _reference_ to
+that variable.  Therefore you would not normally use a `$' or
+parentheses when writing it.  (You can, however, use a variable
+reference in the name if you want the name not to be a constant.)
+
+   If VARIABLE is the name of a builtin function, the builtin function
+is always invoked (even if a `make' variable by that name also exists).
+
+   The `call' function expands the PARAM arguments before assigning
+them to temporary variables.  This means that VARIABLE values
+containing references to builtin functions that have special expansion
+rules, like `foreach' or `if', may not work as you expect.
+
+   Some examples may make this clearer.
+
+   This macro simply reverses its arguments:
+
+     reverse = $(2) $(1)
+
+     foo = $(call reverse,a,b)
+
+Here FOO will contain `b a'.
+
+   This one is slightly more interesting: it defines a macro to search
+for the first instance of a program in `PATH':
+
+     pathsearch = $(firstword $(wildcard $(addsuffix /$(1),$(subst :, ,$(PATH)))))
+
+     LS := $(call pathsearch,ls)
+
+Now the variable LS contains `/bin/ls' or similar.
+
+   The `call' function can be nested.  Each recursive invocation gets
+its own local values for `$(1)', etc. that mask the values of
+higher-level `call'.  For example, here is an implementation of a "map"
+function:
+
+     map = $(foreach a,$(2),$(call $(1),$(a)))
+
+   Now you can MAP a function that normally takes only one argument,
+such as `origin', to multiple values in one step:
+
+     o = $(call map,origin,o map MAKE)
+
+   and end up with O containing something like `file file default'.
+
+   A final caution: be careful when adding whitespace to the arguments
+to `call'.  As with other functions, any whitespace contained in the
+second and subsequent arguments is kept; this can cause strange
+effects.  It's generally safest to remove all extraneous whitespace when
+providing parameters to `call'.
+

+File: make.info,  Node: Value Function,  Next: Eval Function,  Prev: Call Function,  Up: Functions
+
+8.7 The `value' Function
+========================
+
+The `value' function provides a way for you to use the value of a
+variable _without_ having it expanded.  Please note that this does not
+undo expansions which have already occurred; for example if you create
+a simply expanded variable its value is expanded during the definition;
+in that case the `value' function will return the same result as using
+the variable directly.
+
+   The syntax of the `value' function is:
+
+     $(value VARIABLE)
+
+   Note that VARIABLE is the _name_ of a variable; not a _reference_ to
+that variable.  Therefore you would not normally use a `$' or
+parentheses when writing it.  (You can, however, use a variable
+reference in the name if you want the name not to be a constant.)
+
+   The result of this function is a string containing the value of
+VARIABLE, without any expansion occurring.  For example, in this
+makefile:
+
+     FOO = $PATH
+
+     all:
+             @echo $(FOO)
+             @echo $(value FOO)
+
+The first output line would be `ATH', since the "$P" would be expanded
+as a `make' variable, while the second output line would be the current
+value of your `$PATH' environment variable, since the `value' function
+avoided the expansion.
+
+   The `value' function is most often used in conjunction with the
+`eval' function (*note Eval Function::).
+
+
+File: make.info,  Node: Eval Function,  Next: Origin Function,  Prev: Value Function,  Up: Functions
+
+8.8 The `eval' Function
+=======================
+
+The `eval' function is very special: it allows you to define new
+makefile constructs that are not constant; which are the result of
+evaluating other variables and functions.  The argument to the `eval'
+function is expanded, then the results of that expansion are parsed as
+makefile syntax.  The expanded results can define new `make' variables,
+targets, implicit or explicit rules, etc.
+
+   The result of the `eval' function is always the empty string; thus,
+it can be placed virtually anywhere in a makefile without causing
+syntax errors.
+
+   It's important to realize that the `eval' argument is expanded
+_twice_; first by the `eval' function, then the results of that
+expansion are expanded again when they are parsed as makefile syntax.
+This means you may need to provide extra levels of escaping for "$"
+characters when using `eval'.  The `value' function (*note Value
+Function::) can sometimes be useful in these situations, to circumvent
+unwanted expansions.
+
+   Here is an example of how `eval' can be used; this example combines
+a number of concepts and other functions.  Although it might seem
+overly complex to use `eval' in this example, rather than just writing
+out the rules, consider two things: first, the template definition (in
+`PROGRAM_template') could need to be much more complex than it is here;
+and second, you might put the complex, "generic" part of this example
+into another makefile, then include it in all the individual makefiles.
+Now your individual makefiles are quite straightforward.
+
+     PROGRAMS    = server client
+
+     server_OBJS = server.o server_priv.o server_access.o
+     server_LIBS = priv protocol
+
+     client_OBJS = client.o client_api.o client_mem.o
+     client_LIBS = protocol
+
+     # Everything after this is generic
+

+     all: $(PROGRAMS)

+
+8.9 The `origin' Function
+=========================
+
+The `origin' function is unlike most other functions in that it does
+not operate on the values of variables; it tells you something _about_
+a variable.  Specifically, it tells you where it came from.
+
+   The syntax of the `origin' function is:
+
+     $(origin VARIABLE)
+
+   Note that VARIABLE is the _name_ of a variable to inquire about; not
+a _reference_ to that variable.  Therefore you would not normally use a
+`$' or parentheses when writing it.  (You can, however, use a variable
+reference in the name if you want the name not to be a constant.)
+
+   The result of this function is a string telling you how the variable
+VARIABLE was defined:
+
+`undefined'
+     if VARIABLE was never defined.
+
+`default'
+     if VARIABLE has a default definition, as is usual with `CC' and so
+     on.  *Note Variables Used by Implicit Rules: Implicit Variables.
+     Note that if you have redefined a default variable, the `origin'
+     function will return the origin of the later definition.
+
+`environment'
+     if VARIABLE was inherited from the environment provided to `make'.
+
+`environment override'
+     if VARIABLE was inherited from the environment provided to `make',
+     and is overriding a setting for VARIABLE in the makefile as a
+     result of the `-e' option (*note Summary of Options: Options
+     Summary.).
+
+`file'
+     if VARIABLE was defined in a makefile.
+
+`command line'
+     if VARIABLE was defined on the command line.
+
+`override'
+     if VARIABLE was defined with an `override' directive in a makefile
+     (*note The `override' Directive: Override Directive.).
+
+`automatic'
+     if VARIABLE is an automatic variable defined for the execution of
+     the recipe for each rule (*note Automatic Variables::).
+
+   This information is primarily useful (other than for your curiosity)
+to determine if you want to believe the value of a variable.  For
+example, suppose you have a makefile `foo' that includes another
+makefile `bar'.  You want a variable `bletch' to be defined in `bar' if
+you run the command `make -f bar', even if the environment contains a
+definition of `bletch'.  However, if `foo' defined `bletch' before
+including `bar', you do not want to override that definition.  This
+could be done by using an `override' directive in `foo', giving that
+definition precedence over the later definition in `bar';
+unfortunately, the `override' directive would also override any command
+line definitions.  So, `bar' could include:
+
+     ifdef bletch
+     ifeq "$(origin bletch)" "environment"
+     bletch = barf, gag, etc.
+     endif
+     endif
+
+If `bletch' has been defined from the environment, this will redefine
+it.
+
+   If you want to override a previous definition of `bletch' if it came
+from the environment, even under `-e', you could instead write:
+
+     ifneq "$(findstring environment,$(origin bletch))" ""
+     bletch = barf, gag, etc.
+     endif
+
+   Here the redefinition takes place if `$(origin bletch)' returns
+either `environment' or `environment override'.  *Note Functions for
+String Substitution and Analysis: Text Functions.

+
+8.10 The `flavor' Function
+==========================
+
+The `flavor' function is unlike most other functions (and like `origin'
+function) in that it does not operate on the values of variables; it
+tells you something _about_ a variable.  Specifically, it tells you the
+flavor of a variable (*note The Two Flavors of Variables: Flavors.).
+
+   The syntax of the `flavor' function is:
+
+     $(flavor VARIABLE)
+
+   Note that VARIABLE is the _name_ of a variable to inquire about; not
+a _reference_ to that variable.  Therefore you would not normally use a
+`$' or parentheses when writing it.  (You can, however, use a variable
+reference in the name if you want the name not to be a constant.)
+
+   The result of this function is a string that identifies the flavor
+of the variable VARIABLE:
+
+`undefined'
+     if VARIABLE was never defined.
+
+`recursive'
+     if VARIABLE is a recursively expanded variable.
+
+`simple'
+     if VARIABLE is a simply expanded variable.

+
+8.11 The `shell' Function
+=========================
+
+The `shell' function is unlike any other function other than the
+`wildcard' function (*note The Function `wildcard': Wildcard Function.)
+in that it communicates with the world outside of `make'.
+
+   The `shell' function performs the same function that backquotes
+(``') perform in most shells: it does "command expansion".  This means
+that it takes as an argument a shell command and evaluates to the
+output of the command.  The only processing `make' does on the result
+is to convert each newline (or carriage-return / newline pair) to a
+single space.  If there is a trailing (carriage-return and) newline it
+will simply be removed.
+
+   The commands run by calls to the `shell' function are run when the
+function calls are expanded (*note How `make' Reads a Makefile: Reading
+Makefiles.).  Because this function involves spawning a new shell, you
+should carefully consider the performance implications of using the
+`shell' function within recursively expanded variables vs. simply
+expanded variables (*note The Two Flavors of Variables: Flavors.).
+
+   Here are some examples of the use of the `shell' function:
+
+     contents := $(shell cat foo)
+
+sets `contents' to the contents of the file `foo', with a space (rather
+than a newline) separating each line.
+
+     files := $(shell echo *.c)
+
+sets `files' to the expansion of `*.c'.  Unless `make' is using a very
+strange shell, this has the same result as `$(wildcard *.c)' (as long
+as at least one `.c' file exists).

+File: make.info,  Node: Make Control Functions,  Prev: Shell Function,  Up: Functions
+
+8.12 Functions That Control Make
+================================
+
+These functions control the way make runs.  Generally, they are used to
+provide information to the user of the makefile or to cause make to stop
+if some sort of environmental error is detected.
+
+`$(error TEXT...)'
+     Generates a fatal error where the message is TEXT.  Note that the
+     error is generated whenever this function is evaluated.  So, if
+     you put it inside a recipe or on the right side of a recursive
+     variable assignment, it won't be evaluated until later.  The TEXT
+     will be expanded before the error is generated.
+
+     For example,
+
+          ifdef ERROR1
+          $(error error is $(ERROR1))
+          endif
+
+     will generate a fatal error during the read of the makefile if the
+     `make' variable `ERROR1' is defined.  Or,
+
+          ERR = $(error found an error!)
+
+          .PHONY: err
+          err: ; $(ERR)
+
+     will generate a fatal error while `make' is running, if the `err'
+     target is invoked.
+
+`$(warning TEXT...)'
+     This function works similarly to the `error' function, above,
+     except that `make' doesn't exit.  Instead, TEXT is expanded and
+     the resulting message is displayed, but processing of the makefile
+     continues.
+
+     The result of the expansion of this function is the empty string.
+
+`$(info TEXT...)'
+     This function does nothing more than print its (expanded)
+     argument(s) to standard output.  No makefile name or line number
+     is added.  The result of the expansion of this function is the
+     empty string.

+9 How to Run `make'
+*******************
+
+A makefile that says how to recompile a program can be used in more
+than one way.  The simplest use is to recompile every file that is out
+of date.  Usually, makefiles are written so that if you run `make' with
+no arguments, it does just that.
+
+   But you might want to update only some of the files; you might want
+to use a different compiler or different compiler options; you might
+want just to find out which files are out of date without changing them.
+
+   By giving arguments when you run `make', you can do any of these
+things and many others.
+
+   The exit status of `make' is always one of three values:
+`0'
+     The exit status is zero if `make' is successful.
+
+`2'
+     The exit status is two if `make' encounters any errors.  It will
+     print messages describing the particular errors.
+
+`1'
+     The exit status is one if you use the `-q' flag and `make'
+     determines that some target is not already up to date.  *Note

+
+9.1 Arguments to Specify the Makefile
+=====================================
+
+The way to specify the name of the makefile is with the `-f' or
+`--file' option (`--makefile' also works).  For example, `-f altmake'
+says to use the file `altmake' as the makefile.
+
+   If you use the `-f' flag several times and follow each `-f' with an
+argument, all the specified files are used jointly as makefiles.
+
+   If you do not use the `-f' or `--file' flag, the default is to try
+`GNUmakefile', `makefile', and `Makefile', in that order, and use the
+first of these three which exists or can be made (*note Writing
+Makefiles: Makefiles.).
+
+
+File: make.info,  Node: Goals,  Next: Instead of Execution,  Prev: Makefile Arguments,  Up: Running
+
+9.2 Arguments to Specify the Goals
+==================================
+
+The "goals" are the targets that `make' should strive ultimately to
+update.  Other targets are updated as well if they appear as
+prerequisites of goals, or prerequisites of prerequisites of goals, etc.
+
+   By default, the goal is the first target in the makefile (not
+counting targets that start with a period).  Therefore, makefiles are
+usually written so that the first target is for compiling the entire
+program or programs they describe.  If the first rule in the makefile
+has several targets, only the first target in the rule becomes the
+default goal, not the whole list.  You can manage the selection of the
+default goal from within your makefile using the `.DEFAULT_GOAL'
+variable (*note Other Special Variables: Special Variables.).
+
+   You can also specify a different goal or goals with command line
+arguments to `make'.  Use the name of the goal as an argument.  If you
+specify several goals, `make' processes each of them in turn, in the
+order you name them.
+
+   Any target in the makefile may be specified as a goal (unless it
+starts with `-' or contains an `=', in which case it will be parsed as
+a switch or variable definition, respectively).  Even targets not in
+the makefile may be specified, if `make' can find implicit rules that
+say how to make them.
+
+   `Make' will set the special variable `MAKECMDGOALS' to the list of
+goals you specified on the command line.  If no goals were given on the
+command line, this variable is empty.  Note that this variable should
+be used only in special circumstances.
+
+   An example of appropriate use is to avoid including `.d' files
+during `clean' rules (*note Automatic Prerequisites::), so `make' won't
+create them only to immediately remove them again:
+
+     sources = foo.c bar.c
+
+     ifneq ($(MAKECMDGOALS),clean)
+     include $(sources:.c=.d)
+     endif
+
+   One use of specifying a goal is if you want to compile only a part of
+the program, or only one of several programs.  Specify as a goal each
+file that you wish to remake.  For example, consider a directory
+containing several programs, with a makefile that starts like this:
+
+     .PHONY: all
+     all: size nm ld ar as
+
+   If you are working on the program `size', you might want to say
+`make size' so that only the files of that program are recompiled.
+
+   Another use of specifying a goal is to make files that are not
+normally made.  For example, there may be a file of debugging output,
+or a version of the program that is compiled specially for testing,
+which has a rule in the makefile but is not a prerequisite of the
+default goal.
+
+   Another use of specifying a goal is to run the recipe associated with
+a phony target (*note Phony Targets::) or empty target (*note Empty
+Target Files to Record Events: Empty Targets.).  Many makefiles contain
+a phony target named `clean' which deletes everything except source
+files.  Naturally, this is done only if you request it explicitly with
+`make clean'.  Following is a list of typical phony and empty target
+names.  *Note Standard Targets::, for a detailed list of all the
+standard target names which GNU software packages use.
+
+`all'
+     Make all the top-level targets the makefile knows about.
+
+`clean'
+     Delete all files that are normally created by running `make'.
+
+`mostlyclean'
+     Like `clean', but may refrain from deleting a few files that people
+     normally don't want to recompile.  For example, the `mostlyclean'
+     target for GCC does not delete `libgcc.a', because recompiling it
+     is rarely necessary and takes a lot of time.
+
+`distclean'
+`realclean'
+`clobber'
+     Any of these targets might be defined to delete _more_ files than
+     `clean' does.  For example, this would delete configuration files
+     or links that you would normally create as preparation for
+     compilation, even if the makefile itself cannot create these files.
+
+`install'
+     Copy the executable file into a directory that users typically
+     search for commands; copy any auxiliary files that the executable
+     uses into the directories where it will look for them.
+
+`print'
+     Print listings of the source files that have changed.
+
+`tar'
+     Create a tar file of the source files.
+
+`shar'
+     Create a shell archive (shar file) of the source files.
+
+`dist'
+     Create a distribution file of the source files.  This might be a
+     tar file, or a shar file, or a compressed version of one of the
+     above, or even more than one of the above.
+
+`TAGS'
+     Update a tags table for this program.
+
+`check'
+`test'
+     Perform self tests on the program this makefile builds.

+
+9.3 Instead of Executing Recipes
+================================
+
+The makefile tells `make' how to tell whether a target is up to date,
+and how to update each target.  But updating the targets is not always
+what you want.  Certain options specify other activities for `make'.
+
+`-n'
+`--just-print'
+`--dry-run'
+`--recon'
+     "No-op".  The activity is to print what recipe would be used to
+     make the targets up to date, but not actually execute it.  Some
+     recipes are still executed, even with this flag (*note How the
+     `MAKE' Variable Works: MAKE Variable.).
+
+`-t'
+`--touch'
+     "Touch".  The activity is to mark the targets as up to date without
+     actually changing them.  In other words, `make' pretends to compile
+     the targets but does not really change their contents.
+
+`-q'
+`--question'
+     "Question".  The activity is to find out silently whether the
+     targets are up to date already; but execute no recipe in either
+     case.  In other words, neither compilation nor output will occur.
+
+`-W FILE'
+`--what-if=FILE'
+`--assume-new=FILE'
+`--new-file=FILE'
+     "What if".  Each `-W' flag is followed by a file name.  The given
+     files' modification times are recorded by `make' as being the
+     present time, although the actual modification times remain the
+     same.  You can use the `-W' flag in conjunction with the `-n' flag
+     to see what would happen if you were to modify specific files.
+
+   With the `-n' flag, `make' prints the recipe that it would normally
+execute but usually does not execute it.
+
+   With the `-t' flag, `make' ignores the recipes in the rules and uses
+(in effect) the command `touch' for each target that needs to be
+remade.  The `touch' command is also printed, unless `-s' or `.SILENT'
+is used.  For speed, `make' does not actually invoke the program
+`touch'.  It does the work directly.
+
+   With the `-q' flag, `make' prints nothing and executes no recipes,
+but the exit status code it returns is zero if and only if the targets
+to be considered are already up to date.  If the exit status is one,
+then some updating needs to be done.  If `make' encounters an error,
+the exit status is two, so you can distinguish an error from a target
+that is not up to date.
+
+   It is an error to use more than one of these three flags in the same
+invocation of `make'.
+
+   The `-n', `-t', and `-q' options do not affect recipe lines that
+begin with `+' characters or contain the strings `$(MAKE)' or
+`${MAKE}'.  Note that only the line containing the `+' character or the
+strings `$(MAKE)' or `${MAKE}' is run regardless of these options.
+Other lines in the same rule are not run unless they too begin with `+'
+or contain `$(MAKE)' or `${MAKE}' (*Note How the `MAKE' Variable Works:
+MAKE Variable.)
+
+   The `-t' flag prevents phony targets (*note Phony Targets::) from
+being updated, unless there are recipe lines beginning with `+' or
+containing `$(MAKE)' or `${MAKE}'.
+
+   The `-W' flag provides two features:
+
+   * If you also use the `-n' or `-q' flag, you can see what `make'
+     would do if you were to modify some files.
+
+   * Without the `-n' or `-q' flag, when `make' is actually executing
+     recipes, the `-W' flag can direct `make' to act as if some files
+     had been modified, without actually running the recipes for those
+     files.
+
+   Note that the options `-p' and `-v' allow you to obtain other
+information about `make' or about the makefiles in use (*note Summary
+of Options: Options Summary.).

+
+9.4 Avoiding Recompilation of Some Files
+========================================
+
+Sometimes you may have changed a source file but you do not want to
+recompile all the files that depend on it.  For example, suppose you add
+a macro or a declaration to a header file that many other files depend
+on.  Being conservative, `make' assumes that any change in the header
+file requires recompilation of all dependent files, but you know that
+they do not need to be recompiled and you would rather not waste the
+time waiting for them to compile.
+
+   If you anticipate the problem before changing the header file, you
+can use the `-t' flag.  This flag tells `make' not to run the recipes
+in the rules, but rather to mark the target up to date by changing its
+last-modification date.  You would follow this procedure:
+
+  1. Use the command `make' to recompile the source files that really
+     need recompilation, ensuring that the object files are up-to-date
+     before you begin.
+
+  2. Make the changes in the header files.
+
+  3. Use the command `make -t' to mark all the object files as up to
+     date.  The next time you run `make', the changes in the header
+     files will not cause any recompilation.
+
+   If you have already changed the header file at a time when some files
+do need recompilation, it is too late to do this.  Instead, you can use
+the `-o FILE' flag, which marks a specified file as "old" (*note
+Summary of Options: Options Summary.).  This means that the file itself
+will not be remade, and nothing else will be remade on its account.
+Follow this procedure:
+
+  1. Recompile the source files that need compilation for reasons
+     independent of the particular header file, with `make -o
+     HEADERFILE'.  If several header files are involved, use a separate
+     `-o' option for each header file.
+
+  2. Touch all the object files with `make -t'.
+

+File: make.info,  Node: Overriding,  Next: Testing,  Prev: Avoiding Compilation,  Up: Running
+
+9.5 Overriding Variables
+========================
+
+An argument that contains `=' specifies the value of a variable: `V=X'
+sets the value of the variable V to X.  If you specify a value in this
+way, all ordinary assignments of the same variable in the makefile are
+ignored; we say they have been "overridden" by the command line
+argument.
+
+   The most common way to use this facility is to pass extra flags to
+compilers.  For example, in a properly written makefile, the variable
+`CFLAGS' is included in each recipe that runs the C compiler, so a file
+`foo.c' would be compiled something like this:
+
+     cc -c $(CFLAGS) foo.c
+
+   Thus, whatever value you set for `CFLAGS' affects each compilation
+that occurs.  The makefile probably specifies the usual value for
+`CFLAGS', like this:
+
+     CFLAGS=-g
+
+   Each time you run `make', you can override this value if you wish.
+For example, if you say `make CFLAGS='-g -O'', each C compilation will
+be done with `cc -c -g -O'.  (This also illustrates how you can use
+quoting in the shell to enclose spaces and other special characters in
+the value of a variable when you override it.)
+
+   The variable `CFLAGS' is only one of many standard variables that
+exist just so that you can change them this way.  *Note Variables Used
+by Implicit Rules: Implicit Variables, for a complete list.
+
+   You can also program the makefile to look at additional variables of
+your own, giving the user the ability to control other aspects of how
+the makefile works by changing the variables.
+
+   When you override a variable with a command line argument, you can
+define either a recursively-expanded variable or a simply-expanded
+variable.  The examples shown above make a recursively-expanded
+variable; to make a simply-expanded variable, write `:=' instead of
+`='.  But, unless you want to include a variable reference or function
+call in the _value_ that you specify, it makes no difference which kind
+of variable you create.
+
+   There is one way that the makefile can change a variable that you
+have overridden.  This is to use the `override' directive, which is a
+line that looks like this: `override VARIABLE = VALUE' (*note The
+`override' Directive: Override Directive.).
+
+
+File: make.info,  Node: Testing,  Next: Options Summary,  Prev: Overriding,  Up: Running
+
+9.6 Testing the Compilation of a Program
+========================================
+
+Normally, when an error happens in executing a shell command, `make'
+gives up immediately, returning a nonzero status.  No further recipes
+are executed for any target.  The error implies that the goal cannot be
+correctly remade, and `make' reports this as soon as it knows.
+
+   When you are compiling a program that you have just changed, this is
+not what you want.  Instead, you would rather that `make' try compiling
+every file that can be tried, to show you as many compilation errors as
+possible.
+
+   On these occasions, you should use the `-k' or `--keep-going' flag.
+This tells `make' to continue to consider the other prerequisites of
+the pending targets, remaking them if necessary, before it gives up and
+returns nonzero status.  For example, after an error in compiling one
+object file, `make -k' will continue compiling other object files even
+though it already knows that linking them will be impossible.  In
+addition to continuing after failed shell commands, `make -k' will
+continue as much as possible after discovering that it does not know
+how to make a target or prerequisite file.  This will always cause an
+error message, but without `-k', it is a fatal error (*note Summary of
+Options: Options Summary.).
+
+   The usual behavior of `make' assumes that your purpose is to get the
+goals up to date; once `make' learns that this is impossible, it might
+as well report the failure immediately.  The `-k' flag says that the
+real purpose is to test as much as possible of the changes made in the
+program, perhaps to find several independent problems so that you can
+correct them all before the next attempt to compile.  This is why Emacs'
+`M-x compile' command passes the `-k' flag by default.

+
+9.7 Summary of Options
+======================
+
+Here is a table of all the options `make' understands:
+
+`-b'
+`-m'
+     These options are ignored for compatibility with other versions of
+     `make'.
+
+`-B'
+`--always-make'
+     Consider all targets out-of-date.  GNU `make' proceeds to consider
+     targets and their prerequisites using the normal algorithms;
+     however, all targets so considered are always remade regardless of
+     the status of their prerequisites.  To avoid infinite recursion, if
+     `MAKE_RESTARTS' (*note Other Special Variables: Special
+     Variables.) is set to a number greater than 0 this option is
+     disabled when considering whether to remake makefiles (*note How
+     Makefiles Are Remade: Remaking Makefiles.).
+
+`-C DIR'
+`--directory=DIR'
+     Change to directory DIR before reading the makefiles.  If multiple
+     `-C' options are specified, each is interpreted relative to the
+     previous one: `-C / -C etc' is equivalent to `-C /etc'.  This is
+     typically used with recursive invocations of `make' (*note
+     Recursive Use of `make': Recursion.).
+
+`-d'
+     Print debugging information in addition to normal processing.  The
+     debugging information says which files are being considered for
+     remaking, which file-times are being compared and with what
+     results, which files actually need to be remade, which implicit
+     rules are considered and which are applied--everything interesting
+     about how `make' decides what to do.  The `-d' option is
+     equivalent to `--debug=a' (see below).
+
+`--debug[=OPTIONS]'
+     Print debugging information in addition to normal processing.
+     Various levels and types of output can be chosen.  With no
+     arguments, print the "basic" level of debugging.  Possible
+     arguments are below; only the first character is considered, and
+     values must be comma- or space-separated.
+
+    `a (all)'
+          All types of debugging output are enabled.  This is
+          equivalent to using `-d'.
+
+    `b (basic)'
+          Basic debugging prints each target that was found to be
+          out-of-date, and whether the build was successful or not.
+
+    `v (verbose)'
+          A level above `basic'; includes messages about which
+          makefiles were parsed, prerequisites that did not need to be
+          rebuilt, etc.  This option also enables `basic' messages.
+
+    `i (implicit)'
+          Prints messages describing the implicit rule searches for
+          each target.  This option also enables `basic' messages.
+
+    `j (jobs)'
+          Prints messages giving details on the invocation of specific
+          subcommands.
+
+    `m (makefile)'
+          By default, the above messages are not enabled while trying
+          to remake the makefiles.  This option enables messages while
+          rebuilding makefiles, too.  Note that the `all' option does
+          enable this option.  This option also enables `basic'
+          messages.
+
+`-e'
+`--environment-overrides'
+     Give variables taken from the environment precedence over
+     variables from makefiles.  *Note Variables from the Environment:
+     Environment.
+
+`--eval=STRING'
+     Evaluate STRING as makefile syntax.  This is a command-line
+     version of the `eval' function (*note Eval Function::).  The
+     evaluation is performed after the default rules and variables have
+     been defined, but before any makefiles are read.
+
+`-f FILE'
+`--file=FILE'
+`--makefile=FILE'
+     Read the file named FILE as a makefile.  *Note Writing Makefiles:
+     Makefiles.
+
+`-h'
+`--help'
+     Remind you of the options that `make' understands and then exit.
+
+`-i'
+`--ignore-errors'
+     Ignore all errors in recipes executed to remake files.  *Note
+     Errors in Recipes: Errors.
+
+`-I DIR'
+`--include-dir=DIR'
+     Specifies a directory DIR to search for included makefiles.  *Note
+     Including Other Makefiles: Include.  If several `-I' options are
+     used to specify several directories, the directories are searched
+     in the order specified.
+
+`-j [JOBS]'
+`--jobs[=JOBS]'
+     Specifies the number of recipes (jobs) to run simultaneously.
+     With no argument, `make' runs as many recipes simultaneously as
+     possible.  If there is more than one `-j' option, the last one is
+     effective.  *Note Parallel Execution: Parallel, for more
+     information on how recipes are run.  Note that this option is
+     ignored on MS-DOS.
+
+`-k'
+`--keep-going'
+     Continue as much as possible after an error.  While the target that
+     failed, and those that depend on it, cannot be remade, the other
+     prerequisites of these targets can be processed all the same.
+     *Note Testing the Compilation of a Program: Testing.
+
+`-l [LOAD]'
+`--load-average[=LOAD]'
+`--max-load[=LOAD]'
+     Specifies that no new recipes should be started if there are other
+     recipes running and the load average is at least LOAD (a
+     floating-point number).  With no argument, removes a previous load
+     limit.  *Note Parallel Execution: Parallel.
+
+`-L'
+`--check-symlink-times'
+     On systems that support symbolic links, this option causes `make'
+     to consider the timestamps on any symbolic links in addition to the
+     timestamp on the file referenced by those links.  When this option
+     is provided, the most recent timestamp among the file and the
+     symbolic links is taken as the modification time for this target
+     file.
+
+`-n'
+`--just-print'
+`--dry-run'
+`--recon'
+     Print the recipe that would be executed, but do not execute it
+     (except in certain circumstances).  *Note Instead of Executing
+     Recipes: Instead of Execution.
+
+`-o FILE'
+`--old-file=FILE'
+`--assume-old=FILE'
+     Do not remake the file FILE even if it is older than its
+     prerequisites, and do not remake anything on account of changes in
+     FILE.  Essentially the file is treated as very old and its rules
+     are ignored.  *Note Avoiding Recompilation of Some Files: Avoiding
+     Compilation.
+
+`-p'
+`--print-data-base'
+     Print the data base (rules and variable values) that results from
+     reading the makefiles; then execute as usual or as otherwise
+     specified.  This also prints the version information given by the
+     `-v' switch (see below).  To print the data base without trying to
+     remake any files, use `make -qp'.  To print the data base of
+     predefined rules and variables, use `make -p -f /dev/null'.  The
+     data base output contains filename and linenumber information for
+     recipe and variable definitions, so it can be a useful debugging
+     tool in complex environments.
+
+`-q'
+`--question'
+     "Question mode".  Do not run any recipes, or print anything; just
+     return an exit status that is zero if the specified targets are
+     already up to date, one if any remaking is required, or two if an
+     error is encountered.  *Note Instead of Executing Recipes: Instead
+     of Execution.
+
+`-r'
+`--no-builtin-rules'
+     Eliminate use of the built-in implicit rules (*note Using Implicit
+     Rules: Implicit Rules.).  You can still define your own by writing
+     pattern rules (*note Defining and Redefining Pattern Rules:
+     Pattern Rules.).  The `-r' option also clears out the default list
+     of suffixes for suffix rules (*note Old-Fashioned Suffix Rules:
+     Suffix Rules.).  But you can still define your own suffixes with a
+     rule for `.SUFFIXES', and then define your own suffix rules.  Note
+     that only _rules_ are affected by the `-r' option; default
+     variables remain in effect (*note Variables Used by Implicit
+     Rules: Implicit Variables.); see the `-R' option below.
+
+`-R'
+`--no-builtin-variables'
+     Eliminate use of the built-in rule-specific variables (*note
+     Variables Used by Implicit Rules: Implicit Variables.).  You can
+     still define your own, of course.  The `-R' option also
+     automatically enables the `-r' option (see above), since it
+     doesn't make sense to have implicit rules without any definitions
+     for the variables that they use.
+
+`-s'
+`--silent'
+`--quiet'
+     Silent operation; do not print the recipes as they are executed.
+     *Note Recipe Echoing: Echoing.
+
+`-S'
+`--no-keep-going'
+`--stop'
+     Cancel the effect of the `-k' option.  This is never necessary
+     except in a recursive `make' where `-k' might be inherited from
+     the top-level `make' via `MAKEFLAGS' (*note Recursive Use of
+     `make': Recursion.)  or if you set `-k' in `MAKEFLAGS' in your
+     environment.
+
+`-t'
+`--touch'
+     Touch files (mark them up to date without really changing them)
+     instead of running their recipes.  This is used to pretend that the
+     recipes were done, in order to fool future invocations of `make'.
+     *Note Instead of Executing Recipes: Instead of Execution.
+
+`-v'
+`--version'
+     Print the version of the `make' program plus a copyright, a list
+     of authors, and a notice that there is no warranty; then exit.
+
+`-w'
+`--print-directory'
+     Print a message containing the working directory both before and
+     after executing the makefile.  This may be useful for tracking
+     down errors from complicated nests of recursive `make' commands.
+     *Note Recursive Use of `make': Recursion.  (In practice, you
+     rarely need to specify this option since `make' does it for you;
+     see *note The `--print-directory' Option: -w Option.)
+
+`--no-print-directory'
+     Disable printing of the working directory under `-w'.  This option
+     is useful when `-w' is turned on automatically, but you do not
+     want to see the extra messages.  *Note The `--print-directory'
+     Option: -w Option.
+
+`-W FILE'
+`--what-if=FILE'
+`--new-file=FILE'
+`--assume-new=FILE'
+     Pretend that the target FILE has just been modified.  When used
+     with the `-n' flag, this shows you what would happen if you were
+     to modify that file.  Without `-n', it is almost the same as
+     running a `touch' command on the given file before running `make',
+     except that the modification time is changed only in the
+     imagination of `make'.  *Note Instead of Executing Recipes:
+     Instead of Execution.
+
+`--warn-undefined-variables'
+     Issue a warning message whenever `make' sees a reference to an
+     undefined variable.  This can be helpful when you are trying to
+     debug makefiles which use variables in complex ways.

+
+10 Using Implicit Rules
+***********************
+
+Certain standard ways of remaking target files are used very often.  For
+example, one customary way to make an object file is from a C source
+file using the C compiler, `cc'.
+
+   "Implicit rules" tell `make' how to use customary techniques so that
+you do not have to specify them in detail when you want to use them.
+For example, there is an implicit rule for C compilation.  File names
+determine which implicit rules are run.  For example, C compilation
+typically takes a `.c' file and makes a `.o' file.  So `make' applies
+the implicit rule for C compilation when it sees this combination of
+file name endings.
+
+   A chain of implicit rules can apply in sequence; for example, `make'
+will remake a `.o' file from a `.y' file by way of a `.c' file.
+
+   The built-in implicit rules use several variables in their recipes so
+that, by changing the values of the variables, you can change the way
+the implicit rule works.  For example, the variable `CFLAGS' controls
+the flags given to the C compiler by the implicit rule for C
+compilation.
+
+   You can define your own implicit rules by writing "pattern rules".
+
+   "Suffix rules" are a more limited way to define implicit rules.
+Pattern rules are more general and clearer, but suffix rules are
+retained for compatibility.

+
+10.1 Using Implicit Rules
+=========================
+
+To allow `make' to find a customary method for updating a target file,
+all you have to do is refrain from specifying recipes yourself.  Either
+write a rule with no recipe, or don't write a rule at all.  Then `make'
+will figure out which implicit rule to use based on which kind of
+source file exists or can be made.
+
+   For example, suppose the makefile looks like this:
+
+     foo : foo.o bar.o
+             cc -o foo foo.o bar.o $(CFLAGS) $(LDFLAGS)
+
+Because you mention `foo.o' but do not give a rule for it, `make' will
+automatically look for an implicit rule that tells how to update it.
+This happens whether or not the file `foo.o' currently exists.
+
+   If an implicit rule is found, it can supply both a recipe and one or
+more prerequisites (the source files).  You would want to write a rule
+for `foo.o' with no recipe if you need to specify additional
+prerequisites, such as header files, that the implicit rule cannot
+supply.
+
+   Each implicit rule has a target pattern and prerequisite patterns.
+There may be many implicit rules with the same target pattern.  For
+example, numerous rules make `.o' files: one, from a `.c' file with the
+C compiler; another, from a `.p' file with the Pascal compiler; and so
+on.  The rule that actually applies is the one whose prerequisites
+exist or can be made.  So, if you have a file `foo.c', `make' will run
+the C compiler; otherwise, if you have a file `foo.p', `make' will run
+the Pascal compiler; and so on.
+
+   Of course, when you write the makefile, you know which implicit rule
+you want `make' to use, and you know it will choose that one because you
+know which possible prerequisite files are supposed to exist.  *Note
+Catalogue of Implicit Rules: Catalogue of Rules, for a catalogue of all
+the predefined implicit rules.
+
+   Above, we said an implicit rule applies if the required
+prerequisites "exist or can be made".  A file "can be made" if it is
+mentioned explicitly in the makefile as a target or a prerequisite, or
+if an implicit rule can be recursively found for how to make it.  When
+an implicit prerequisite is the result of another implicit rule, we say
+that "chaining" is occurring.  *Note Chains of Implicit Rules: Chained
+Rules.
+
+   In general, `make' searches for an implicit rule for each target, and
+for each double-colon rule, that has no recipe.  A file that is
+mentioned only as a prerequisite is considered a target whose rule
+specifies nothing, so implicit rule search happens for it.  *Note
+Implicit Rule Search Algorithm: Implicit Rule Search, for the details
+of how the search is done.
+
+   Note that explicit prerequisites do not influence implicit rule
+search.  For example, consider this explicit rule:
+
+     foo.o: foo.p
+
+The prerequisite on `foo.p' does not necessarily mean that `make' will
+remake `foo.o' according to the implicit rule to make an object file, a
+`.o' file, from a Pascal source file, a `.p' file.  For example, if
+`foo.c' also exists, the implicit rule to make an object file from a C
+source file is used instead, because it appears before the Pascal rule
+in the list of predefined implicit rules (*note Catalogue of Implicit
+Rules: Catalogue of Rules.).
+
+   If you do not want an implicit rule to be used for a target that has
+no recipe, you can give that target an empty recipe by writing a
+semicolon (*note Defining Empty Recipes: Empty Recipes.).

+
+Link object files or libraries together to form another library, or to
+create an executable program.
+
+LINK-COMMAND is a command using the C compiler that you would use to create
+a program from several object files.
+
+The following components of LINK-COMMAND are treated specially:
+
+  -all-static       do not do any dynamic linking at all
+  -avoid-version    do not add a version suffix if possible
+  -bindir BINDIR    specify path to binaries directory (for systems where
+                    libraries must be found in the PATH setting at runtime)
+  -dlopen FILE      \`-dlpreopen' FILE if it cannot be dlopened at runtime
+  -dlpreopen FILE   link in FILE and add its symbols to lt_preloaded_symbols
+  -export-dynamic   allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
+  -export-symbols SYMFILE
+                    try to export only the symbols listed in SYMFILE
+  -export-symbols-regex REGEX
+                    try to export only the symbols matching REGEX
+  -LLIBDIR          search LIBDIR for required installed libraries
+  -lNAME            OUTPUT-FILE requires the installed library libNAME
+  -module           build a library that can dlopened
+  -no-fast-install  disable the fast-install mode
+  -no-install       link a not-installable executable
+  -no-undefined     declare that a library does not refer to external symbols
+  -o OUTPUT-FILE    create OUTPUT-FILE from the specified objects
+  -objectlist FILE  Use a list of object files found in FILE to specify objects
+  -precious-files-regex REGEX
+                    don't remove output files matching REGEX
+  -release RELEASE  specify package release information
+  -rpath LIBDIR     the created library will eventually be installed in LIBDIR
+  -R[ ]LIBDIR       add LIBDIR to the runtime path of programs and libraries
+  -shared           only do dynamic linking of libtool libraries
+  -shrext SUFFIX    override the standard shared library file extension
+  -static           do not do any dynamic linking of uninstalled libtool libraries
+  -static-libtool-libs
+                    do not do any dynamic linking of libtool libraries
+  -version-info CURRENT[:REVISION[:AGE]]
+                    specify library version info [each variable defaults to 0]
+  -weak LIBNAME     declare that the target provides the LIBNAME interface
+  -Wc,FLAG
+  -Xcompiler FLAG   pass linker-specific FLAG directly to the compiler
+  -Wl,FLAG
+  -Xlinker FLAG     pass linker-specific FLAG directly to the linker
+  -XCClinker FLAG   pass link-specific FLAG to the compiler driver (CC)
+
+All other options (arguments beginning with \`-') are ignored.
+
+Every other argument is treated as a filename.  Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
+only library objects (\`.lo' files) may be specified, and \`-rpath' is
+required, except when creating a convenience library.
+
+If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created
+using \`ar' and \`ranlib', or on Windows using \`lib'.
+
+If OUTPUT-FILE ends in \`.lo' or \`.${objext}', then a reloadable object file
+is created, otherwise an executable program is created."

+                  GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+^L
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it
+becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+^L
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control
+compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+^L
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+^L
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+^L
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+^L
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply, and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License
+may add an explicit geographical distribution limitation excluding those
+countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+^L
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+^L
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms
+of the ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.
+It is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should
+have at least the "copyright" line and a pointer to where the full
+notice is found.
+
+
+    <one line to give the library's name and a brief idea of what it
+does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301  USA
+
+Also add information on how to contact you by electronic and paper
+mail.
+
+You should also get your employer (if you work as a programmer) or
+your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

+\`configure' configures libltdl 2.4.2 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR        program executables [EPREFIX/libexec]

+  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
+  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
+  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
+  --infodir=DIR           info documentation [DATAROOTDIR/info]

+  --with-sysroot=DIR Search for dependent libraries within DIR
+                        (or the compiler's sysroot if not specified).
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+.SH DESCRIPTION
+Run GNU M4 on the FILES, avoiding useless runs.  Output the traces if tracing,
+the frozen file if freezing, otherwise the expansion of the FILES.
+.PP
+If some of the FILES are named `FILE.m4f' they are considered to be M4
+frozen files of all the previous files (which are therefore not loaded).
+If `FILE.m4f' is not found, then `FILE.m4' will be used, together with
+all the previous files.
+.PP
+Some files may be optional, i.e., will only be processed if found in the
+include path, but then must end in `.m4?';  the question mark is not part of

+.SH SYNOPSIS
+.B config.guess
+[\fIOPTION\fR]
+.SH DESCRIPTION
+The GNU build system distinguishes three types of machines, the
+`build' machine on which the compilers are run, the `host' machine
+on which the package being built will run, and, exclusively when you
+build a compiler, assembler etc., the `target' machine, for which the
+compiler being built will produce code.
+
+This script will guess the type of the `build' machine.

+.SH "ENVIRONMENT VARIABLES"
+config.guess might need to compile and run C code, hence it needs a
+compiler for the `build' machine: use the environment variable
+`CC_FOR_BUILD' to specify the compiler for the build machine.  If
+`CC_FOR_BUILD' is not specified, `CC' will be used.  Be sure to
+specify `CC_FOR_BUILD' is `CC' is a cross-compiler to the `host'
+machine.
+
+  CC_FOR_BUILD    a native C compiler, defaults to `cc'
+  CC              a native C compiler, the previous variable is preferred

+By default, sparse SOURCE files are detected by a crude heuristic and the

+selected by \fB\-\-sparse\fR=\fIauto\fR.  Specify \fB\-\-sparse\fR=\fIalways\fR to create a sparse DEST
+file whenever the SOURCE file contains a long enough sequence of zero bytes.
+Use \fB\-\-sparse\fR=\fInever\fR to inhibit creation of sparse files.
+.PP
+When \fB\-\-reflink\fR[=\fIalways\fR] is specified, perform a lightweight copy, where the
+data blocks are copied only when modified.  If this is not possible the copy
+fails, or if \fB\-\-reflink\fR=\fIauto\fR is specified, fall back to a standard copy.
+.PP
+The backup suffix is '~', unless set with \fB\-\-suffix\fR or SIMPLE_BACKUP_SUFFIX.
+The version control method may be selected via the \fB\-\-backup\fR option or through
+the VERSION_CONTROL environment variable.  Here are the values:
+.TP
+none, off

+numbered, t
+make numbered backups
+.TP
+existing, nil
+numbered if numbered backups exist, simple otherwise
+.TP
+simple, never
+always make simple backups
+.PP
+As a special case, cp makes a backup of SOURCE when the force and backup
+options are given and SOURCE and DEST are the same name for an existing,
+regular file.

+.PP
+Description of compile mode:
+.PP
+Compile a source file into a libtool library object.
+.PP
+This mode accepts the following additional options:
+.TP
+\fB\-o\fR OUTPUT\-FILE

+.TP
+\fB\-Wc\fR,FLAG
+pass FLAG directly to the compiler
+.PP
+COMPILE\-COMMAND is a command to be used in creating a `standard' object file
+from the given SOURCEFILE.
+.PP
+The output file name is determined by removing the directory component from
+SOURCEFILE, then substituting the C source code suffix `.c' with the
+library object suffix, `.lo'.
+.PP
+Description of link mode:
+.PP
+Link object files or libraries together to form another library, or to
+create an executable program.
+.PP
+LINK\-COMMAND is a command using the C compiler that you would use to create
+a program from several object files.
+.PP
+The following components of LINK\-COMMAND are treated specially:
+.TP
+\fB\-all\-static\fR
+do not do any dynamic linking at all
+.TP
+\fB\-avoid\-version\fR
+do not add a version suffix if possible
+.TP
+\fB\-bindir\fR BINDIR
+specify path to binaries directory (for systems where
+libraries must be found in the PATH setting at runtime)
+.TP
+\fB\-dlopen\fR FILE
+`\-dlpreopen' FILE if it cannot be dlopened at runtime
+.TP
+\fB\-dlpreopen\fR FILE
+link in FILE and add its symbols to lt_preloaded_symbols
+.TP
+\fB\-export\-dynamic\fR
+allow symbols from OUTPUT\-FILE to be resolved with dlsym(3)
+.TP
+\fB\-export\-symbols\fR SYMFILE
+try to export only the symbols listed in SYMFILE
+.TP
+\fB\-export\-symbols\-regex\fR REGEX
+try to export only the symbols matching REGEX
+.TP
+\fB\-LLIBDIR\fR
+search LIBDIR for required installed libraries

+\fB\-no\-undefined\fR
+declare that a library does not refer to external symbols
+.TP
+\fB\-o\fR OUTPUT\-FILE
+create OUTPUT\-FILE from the specified objects
+.TP
+\fB\-objectlist\fR FILE
+Use a list of object files found in FILE to specify objects
+.TP
+\fB\-precious\-files\-regex\fR REGEX
+don't remove output files matching REGEX
+.TP
+\fB\-release\fR RELEASE
+specify package release information
+.TP
+\fB\-rpath\fR LIBDIR
+the created library will eventually be installed in LIBDIR
+.TP
+\fB\-R[\fR ]LIBDIR
+add LIBDIR to the runtime path of programs and libraries
+.TP
+\fB\-shared\fR
+only do dynamic linking of libtool libraries
+.TP
+\fB\-shrext\fR SUFFIX
+override the standard shared library file extension
+.TP
+\fB\-static\fR
+do not do any dynamic linking of uninstalled libtool libraries
+.TP
+\fB\-static\-libtool\-libs\fR
+do not do any dynamic linking of libtool libraries
+.TP
+\fB\-version\-info\fR CURRENT[:REVISION[:AGE]]
+specify library version info [each variable defaults to 0]
+.TP
+\fB\-weak\fR LIBNAME
+declare that the target provides the LIBNAME interface
+.HP
+\fB\-Wc\fR,FLAG
+.TP
+\fB\-Xcompiler\fR FLAG
+pass linker\-specific FLAG directly to the compiler
+.HP
+\fB\-Wl\fR,FLAG
+.TP
+\fB\-Xlinker\fR FLAG
+pass linker\-specific FLAG directly to the linker
+.TP
+\fB\-XCClinker\fR FLAG
+pass link\-specific FLAG to the compiler driver (CC)
+.PP
+All other options (arguments beginning with `\-') are ignored.
+.PP
+Every other argument is treated as a filename.  Files ending in `.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+.PP
+If the OUTPUT\-FILE ends in `.la', then a libtool library is created,
+only library objects (`.lo' files) may be specified, and `\-rpath' is
+required, except when creating a convenience library.
+.PP
+If OUTPUT\-FILE ends in `.a' or `.lib', then a standard library is created
+using `ar' and `ranlib', or on Windows using `lib'.
+.PP
+If OUTPUT\-FILE ends in `.lo' or `.o', then a reloadable object file
+is created, otherwise an executable program is created.
+.PP
+Description of execute mode:
+.PP
+Automatically set library path, then run a program.
+.PP
+This mode accepts the following additional options:
+.TP
+\fB\-dlopen\fR FILE
+add the directory containing FILE to the library path
+.PP
+This mode sets the library path environment variable according to `\-dlopen'
+flags.
+.PP
+If any of the ARGS are libtool executable wrappers, then they are translated
+into their corresponding uninstalled binary, and any of their required library
+directories are added to the library path.
+.PP
+Then, COMMAND is executed, with ARGS as arguments.
+.PP
+Description of install mode:
+.PP
+Install executables or libraries.
+.PP
+INSTALL\-COMMAND is the installation command.  The first component should be
+either the `install' or `cp' program.
+.PP
+The following components of INSTALL\-COMMAND are treated specially:
+.TP
+\fB\-inst\-prefix\-dir\fR PREFIX\-DIR
+Use PREFIX\-DIR as a staging area for installation
+.PP
+The rest of the components are interpreted as arguments to that command (only
+BSD\-compatible install options are recognized).
+.PP
+Description of finish mode:
+.PP
+Complete the installation of libtool libraries.
+.PP
+Each LIBDIR is a directory that contains libtool libraries.
+.PP
+The commands that this mode executes may require superuser privileges.  Use
+the `\-\-dry\-run' option if you just want to see what would be executed.
+.PP
+Description of uninstall mode:
+.PP
+Remove libraries from an installation directory.
+.PP
+RM is the name of the program to use to delete files associated with each FILE
+(typically `/bin/rm').  RM\-OPTIONS are options (such as `\-f') to be passed
+to RM.
+.PP
+If FILE is a libtool library, all the files associated with it are deleted.
+Otherwise, only FILE itself is deleted using RM.
+.PP
+Description of clean mode:
+.PP
+Remove files from the build directory.
+.PP
+RM is the name of the program to use to delete files associated with each FILE
+(typically `/bin/rm').  RM\-OPTIONS are options (such as `\-f') to be passed
+to RM.
+.PP
+If FILE is a libtool library, object or program, all the files associated
+with it are deleted. Otherwise, only FILE itself is deleted using RM.

+.TH MAKE 1 "22 August 1989" "GNU" "LOCAL USER COMMANDS"
+.SH NAME
+make \- GNU make utility to maintain groups of programs
+.SH SYNOPSIS
+.B "make "
+[
+.B \-f
+.I makefile
+] [ options ] ... [ targets ] ...
+.SH WARNING
+This man page is an extract of the documentation of GNU
+.IR make .
+It is updated only occasionally, because the GNU project does not use nroff.
+For complete, current documentation, refer to the Info file
+.B make.info
+which is made from the Texinfo source file
+.BR make.texi .
+.SH DESCRIPTION
+.LP
+The purpose of the
+.I make
+utility is to determine automatically which
+pieces of a large program need to be recompiled, and issue the commands to
+recompile them.
+The manual describes the GNU implementation of
+.IR make ,
+which was written by Richard Stallman and Roland McGrath, and is
+currently maintained by Paul Smith.
+Our examples show C programs, since they are most common, but you can use
+.I make
+with any programming language whose compiler can be run with a
+shell command.
+In fact,
+.I make
+is not limited to programs.
+You can use it to describe any task where some files must be
+updated automatically from others whenever the others change.
+.LP
+To prepare to use
+.IR make ,
+you must write a file called the
+.I makefile
+that describes the relationships among files in your program, and the
+states the commands for updating each file.
+In a program, typically the executable file is updated from object
+files, which are in turn made by compiling source files.
+.LP
+Once a suitable makefile exists, each time you change some source files,
+this simple shell command:
+.sp 1
+.RS
+.B make
+.RE
+.sp 1
+suffices to perform all necessary recompilations.
+The
+.I make
+program uses the makefile data base and the last-modification times
+of the files to decide which of the files need to be updated.
+For each of those files, it issues the commands recorded in the data base.
+.LP
+.I make
+executes commands in the
+.I makefile
+to update
+one or more target
+.IR names ,
+where
+.I name
+is typically a program.
+If no
+.B \-f
+option is present,
+.I make
+will look for the makefiles
+.IR GNUmakefile ,
+.IR makefile ,
+and
+.IR Makefile ,
+in that order.
+.LP
+Normally you should call your makefile either
+.I makefile
+or
+.IR Makefile .
+(We recommend
+.I Makefile
+because it appears prominently near the beginning of a directory
+listing, right near other important files such as
+.IR  README .)
+The first name checked,
+.IR GNUmakefile ,
+is not recommended for most makefiles.
+You should use this name if you have a makefile that is specific to GNU
+.IR make ,
+and will not be understood by other versions of
+.IR make .
+If
+.I makefile
+is `\-', the standard input is read.
+.LP
+.I make
+updates a target if it depends on prerequisite files
+that have been modified since the target was last modified,
+or if the target does not exist.
+.SH OPTIONS
+.sp 1
+.TP 0.5i
+.BR \-b , " \-m"
+These options are ignored for compatibility with other versions of
+.IR make .
+.TP 0.5i
+.BR \-B , " \-\-always\-make"
+Unconditionally make all targets.
+.TP 0.5i
+\fB\-C\fR \fIdir\fR, \fB\-\-directory\fR=\fIdir\fR
+Change to directory
+.I dir
+before reading the makefiles or doing anything else.
+If multiple
+.B \-C
+options are specified, each is interpreted relative to the
+previous one:
+.BR "\-C " /
+.BR "\-C " etc
+is equivalent to
+.BR "\-C " /etc.
+This is typically used with recursive invocations of
+.IR make .
+.TP 0.5i
+.B \-d
+Print debugging information in addition to normal processing.
+The debugging information says which files are being considered for
+remaking, which file-times are being compared and with what results,
+which files actually need to be remade, which implicit rules are
+considered and which are applied---everything interesting about how
+.I make
+decides what to do.
+.TP 0.5i
+.BI \-\-debug "[=FLAGS]"
+Print debugging information in addition to normal processing.
+If the
+.I FLAGS
+are omitted, then the behavior is the same as if
+.B \-d
+was specified.
+.I FLAGS
+may be
+.I a
+for all debugging output (same as using
+.BR \-d ),
+.I b
+for basic debugging,
+.I v
+for more verbose basic debugging,
+.I i
+for showing implicit rules,
+.I j
+for details on invocation of commands, and
+.I m
+for debugging while remaking makefiles.
+.TP 0.5i
+.BR \-e , " \-\-environment\-overrides"
+Give variables taken from the environment precedence
+over variables from makefiles.
+.TP 0.5i
+\fB\-f\fR \fIfile\fR, \fB\-\-file\fR=\fIfile\fR, \fB\-\-makefile\fR=\fIFILE\fR
+Use
+.I file
+as a makefile.
+.TP 0.5i
+.BR \-i , " \-\-ignore\-errors"
+Ignore all errors in commands executed to remake files.
+.TP 0.5i
+\fB\-I\fR \fIdir\fR, \fB\-\-include\-dir\fR=\fIdir\fR
+Specifies a directory
+.I dir
+to search for included makefiles.
+If several
+.B \-I
+options are used to specify several directories, the directories are
+searched in the order specified.
+Unlike the arguments to other flags of
+.IR make ,
+directories given with
+.B \-I
+flags may come directly after the flag:
+.BI \-I dir
+is allowed, as well as
+.BI "\-I " dir.
+This syntax is allowed for compatibility with the C
+preprocessor's
+.B \-I
+flag.
+.TP 0.5i
+\fB\-j\fR [\fIjobs\fR], \fB\-\-jobs\fR[=\fIjobs\fR]
+Specifies the number of
+.I jobs
+(commands) to run simultaneously.
+If there is more than one
+.B \-j
+option, the last one is effective.
+If the
+.B \-j
+option is given without an argument,
+.IR make
+will not limit the number of jobs that can run simultaneously.
+.TP 0.5i
+.BR \-k , " \-\-keep\-going"
+Continue as much as possible after an error.
+While the target that failed, and those that depend on it, cannot
+be remade, the other dependencies of these targets can be processed
+all the same.
+.TP 0.5i
+\fB\-l\fR [\fIload\fR], \fB\-\-load\-average\fR[=\fIload\fR]
+Specifies that no new jobs (commands) should be started if there are
+others jobs running and the load average is at least
+.I load
+(a floating-point number).
+With no argument, removes a previous load limit.
+.TP 0.5i
+.BR \-L , " \-\-check\-symlink\-times"
+Use the latest mtime between symlinks and target.
+.TP 0.5i
+.BR \-n , " \-\-just\-print" , " \-\-dry\-run" , " \-\-recon"
+Print the commands that would be executed, but do not execute them (except in
+certain circumstances).
+.TP 0.5i
+\fB\-o\fR \fIfile\fR, \fB\-\-old\-file\fR=\fIfile\fR, \fB\-\-assume\-old\fR=\fIfile\fR
+Do not remake the file
+.I file
+even if it is older than its dependencies, and do not remake anything
+on account of changes in
+.IR file .
+Essentially the file is treated as very old and its rules are ignored.
+.TP 0.5i
+.BR \-p , " \-\-print\-data\-base"
+Print the data base (rules and variable values) that results from
+reading the makefiles; then execute as usual or as otherwise
+specified.
+This also prints the version information given by the
+.B \-v
+switch (see below).
+To print the data base without trying to remake any files, use
+.B make
+.B \-p
+.BI \-f /dev/null.
+.TP 0.5i
+.BR \-q , " \-\-question"
+``Question mode''.
+Do not run any commands, or print anything; just return an exit status
+that is zero if the specified targets are already up to date, nonzero
+otherwise.
+.TP 0.5i
+.BR \-r , " \-\-no\-builtin\-rules"
+Eliminate use of the built\-in implicit rules.
+Also clear out the default list of suffixes for suffix rules.
+.TP 0.5i
+.BR \-R , " \-\-no\-builtin\-variables"
+Don't define any built\-in variables.
+.TP 0.5i
+.BR \-s , " \-\-silent" , " \-\-quiet"
+Silent operation; do not print the commands as they are executed.
+.TP 0.5i
+.BR \-S , " \-\-no\-keep\-going" , " \-\-stop"
+Cancel the effect of the
+.B \-k
+option.
+This is never necessary except in a recursive
+.I make
+where
+.B \-k
+might be inherited from the top-level
+.I make
+via MAKEFLAGS or if you set
+.B \-k
+in MAKEFLAGS in your environment.
+.TP 0.5i
+.BR \-t , " \-\-touch"
+Touch files (mark them up to date without really changing them)
+instead of running their commands.
+This is used to pretend that the commands were done, in order to fool
+future invocations of
+.IR make .
+.TP 0.5i
+.BR \-v , " \-\-version"
+Print the version of the
+.I make
+program plus a copyright, a list of authors and a notice that there
+is no warranty.
+.TP 0.5i
+.BR \-w , " \-\-print\-directory"
+Print a message containing the working directory
+before and after other processing.
+This may be useful for tracking down errors from complicated nests of
+recursive
+.I make
+commands.
+.TP 0.5i
+.B \-\-no\-print\-directory
+Turn off
+.BR \-w ,
+even if it was turned on implicitly.
+.TP 0.5i
+\fB\-W\fR \fIfile\fR, \fB\-\-what\-if\fR=\fIfile\fR, \fB\-\-new\-file\fR=\fIfile\fR, \fB\-\-assume\-new\fR=\fIfile\fR
+Pretend that the target
+.I file
+has just been modified.
+When used with the
+.B \-n
+flag, this shows you what would happen if you were to modify that file.
+Without
+.BR \-n ,
+it is almost the same as running a
+.I touch
+command on the given file before running
+.IR make ,
+except that the modification time is changed only in the imagination of
+.IR make .
+.TP 0.5i
+.B \-\-warn\-undefined\-variables
+Warn when an undefined variable is referenced.
+.SH "EXIT STATUS"
+GNU
+.I make
+exits with a status of zero if all makefiles were successfully parsed
+and no targets that were built failed.  A status of one will be returned
+if the
+.B \-q
+flag was used and
+.I make
+determines that a target needs to be rebuilt.  A status of two will be
+returned if any errors were encountered.

+
+Generate a configuration script from a TEMPLATE-FILE if given, or
+\`configure.ac' if present, or else \`configure.in'.  Output is sent
+to the standard output if TEMPLATE-FILE is given, else into
+\`configure'.
+

+
+Run GNU M4 on the FILES, avoiding useless runs.  Output the traces if tracing,
+the frozen file if freezing, otherwise the expansion of the FILES.
+
+If some of the FILES are named \`FILE.m4f\' they are considered to be M4
+frozen files of all the previous files (which are therefore not loaded).
+If \`FILE.m4f\' is not found, then \`FILE.m4\' will be used, together with
+all the previous files.
+
+Some files may be optional, i.e., will only be processed if found in the
+include path, but then must end in \`.m4?\';  the question mark is not part of
+the actual file name.
+
+Operation modes:
+  -h, --help               print this help, then exit
+  -V, --version            print version number, then exit
+  -v, --verbose            verbosely report processing
+  -d, --debug              don\'t remove temporary files
+  -o, --output=FILE        save output in FILE (defaults to \`-\', stdout)
+  -f, --force              don\'t rely on cached values
+  -W, --warnings=CATEGORY  report the warnings falling in CATEGORY
+  -l, --language=LANG      specify the set of M4 macros to use
+  -C, --cache=DIRECTORY    preserve results for future runs in DIRECTORY
+      --no-cache           disable the cache
+  -m, --mode=OCTAL         change the non trace output file mode (0666)
+  -M, --melt               don\'t use M4 frozen files
+
+Languages include:
+  \`Autoconf\'   create Autoconf configure scripts
+  \`Autotest\'   create Autotest test suites
+  \`M4sh\'       create M4sh shell scripts
+  \`M4sugar\'    create M4sugar output
+
+" . Autom4te::ChannelDefs::usage . "
+
+The environment variables \`M4\' and \`WARNINGS\' are honored.
+
+Library directories:
+  -B, --prepend-include=DIR  prepend directory DIR to search path
+  -I, --include=DIR          append directory DIR to search path
+
+Tracing:
+  -t, --trace=MACRO[:FORMAT]  report the MACRO invocations
+  -p, --preselect=MACRO       prepare to trace MACRO in a future run
+
+Freezing:
+  -F, --freeze   produce an M4 frozen state file for FILES
+
+FORMAT defaults to \`\$f:\$l:\$n:\$%\', and can use the following escapes:
+  \$\$     literal \$
+  \$f     file where macro was called
+  \$l     line where macro was called
+  \$d     nesting depth of macro call
+  \$n     name of the macro
+  \$NUM   argument NUM, unquoted and with newlines
+  \$SEP\@  all arguments, with newlines, quoted, and separated by SEP
+  \$SEP*  all arguments, with newlines, unquoted, and separated by SEP
+  \$SEP%  all arguments, without newlines, unquoted, and separated by SEP
+SEP can be empty for the default (comma for \@ and *, colon for %),
+a single character for that character, or {STRING} to use a string.

+      # Until Automake 1.6.3, .info files were built in the
+      # source tree.  This was an obstacle to the support of
+      # non-distributed .info files, and non-distributed .texi
+      # files.
+      #
+      # * Non-distributed .texi files is important in some packages
+      #   where .texi files are built at make time, probably using
+      #   other binaries built in the package itself, maybe using
+      #   tools or information found on the build host.  Because
+      #   these files are not distributed they are always rebuilt
+      #   at make time; they should therefore not lie in the source
+      #   directory.  One plan was to support this using
+      #   nodist_info_TEXINFOS or something similar.  (Doing this
+      #   requires some sanity checks.  For instance Automake should
+      #   not allow:
+      #      dist_info_TEXINFOS = foo.texi
+      #      nodist_foo_TEXINFOS = included.texi
+      #   because a distributed file should never depend on a
+      #   non-distributed file.)
+      #
+      # * If .texi files are not distributed, then .info files should
+      #   not be distributed either.  There are also cases where one
+      #   wants to distribute .texi files, but does not want to
+      #   distribute the .info files.  For instance the Texinfo package
+      #   distributes the tool used to build these files; it would
+      #   be a waste of space to distribute them.  It's not clear
+      #   which syntax we should use to indicate that .info files should
+      #   not be distributed.  Akim Demaille suggested that eventually
+      #   we switch to a new syntax:
+      #   |  Maybe we should take some inspiration from what's already
+      #   |  done in the rest of Automake.  Maybe there is too much
+      #   |  syntactic sugar here, and you want
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  with a bit of magic to have bar.info represent the whole
+      #   |  bar*info set.  That's a lot more verbose that the current
+      #   |  situation, but it is # not new, hence the user has less
+      #   |  to learn.
+      #	  |
+      #   |  But there is still too much room for meaningless specs:
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     dist_PS = bar.ps something-written-by-hand.ps
+      #   |     nodist_bar_ps_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  here bar.texi is dist_ in line 2, and nodist_ in 4.
+      #
+      # Back to the point, it should be clear that in order to support
+      # non-distributed .info files, we need to build them in the
+      # build tree, not in the source tree (non-distributed .texi
+      # files are less of a problem, because we do not output build
+      # rules for them).  In Automake 1.7 .info build rules have been
+      # largely cleaned up so that .info files get always build in the
+      # build tree, even when distributed.  The idea was that
+      #   (1) if during a VPATH build the .info file was found to be
+      #       absent or out-of-date (in the source tree or in the
+      #       build tree), Make would rebuild it in the build tree.
+      #       If an up-to-date source-tree of the .info file existed,
+      #       make would not rebuild it in the build tree.
+      #   (2) having two copies of .info files, one in the source tree
+      #       and one (newer) in the build tree is not a problem
+      #       because 'make dist' always pick files in the build tree
+      #       first.
+      # However it turned out the be a bad idea for several reasons:
+      #   * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+      #     like GNU Make on point (1) above.  These implementations
+      #     of Make would always rebuild .info files in the build
+      #     tree, even if such files were up to date in the source
+      #     tree.  Consequently, it was impossible to perform a VPATH
+      #     build of a package containing Texinfo files using these
+      #     Make implementations.
+      #     (Refer to the Autoconf Manual, section "Limitation of
+      #     Make", paragraph "VPATH", item "target lookup", for
+      #     an account of the differences between these
+      #     implementations.)
+      #   * The GNU Coding Standards require these files to be built
+      #     in the source-tree (when they are distributed, that is).
+      #   * Keeping a fresher copy of distributed files in the
+      #     build tree can be annoying during development because
+      #     - if the files is kept under CVS, you really want it
+      #       to be updated in the source tree
+      #     - it is confusing that 'make distclean' does not erase
+      #       all files in the build tree.
+      #
+      # Consequently, starting with Automake 1.8, .info files are
+      # built in the source tree again.  Because we still plan to
+      # support non-distributed .info files at some point, we
+      # have a single variable ($INSRC) that controls whether
+      # the current .info file must be built in the source tree
+      # or in the build tree.  Actually this variable is switched
+      # off in two cases:
+      #  (1) For '.info' files that appear to be cleaned; this is for
+      #      backward compatibility with package such as Texinfo,
+      #      which do things like
+      #        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+      #        DISTCLEANFILES = texinfo texinfo-* info*.info*
+      #        # Do not create info files for distribution.
+      #        dist-info:
+      #      in order not to distribute .info files.
+      #  (2) When the undocumented option 'info-in-builddir' is given.
+      #      This is done to allow the developers of GCC, GDB, GNU
+      #      binutils and the GNU bfd library to force the '.info' files
+      #      to be generated in the builddir rather than the srcdir, as
+      #      was once done when the (now removed) 'cygnus' option was
+      #      given.  See automake bug#11034 for more discussion.

+      # non-distributed .info files, and non-distributed .texi
+      # files.
+      #
+      # * Non-distributed .texi files is important in some packages
+      #   where .texi files are built at make time, probably using
+      #   other binaries built in the package itself, maybe using
+      #   tools or information found on the build host.  Because
+      #   these files are not distributed they are always rebuilt
+      #   at make time; they should therefore not lie in the source
+      #   directory.  One plan was to support this using
+      #   nodist_info_TEXINFOS or something similar.  (Doing this
+      #   requires some sanity checks.  For instance Automake should
+      #   not allow:
+      #      dist_info_TEXINFOS = foo.texi
+      #      nodist_foo_TEXINFOS = included.texi
+      #   because a distributed file should never depend on a
+      #   non-distributed file.)
+      #
+      # * If .texi files are not distributed, then .info files should
+      #   not be distributed either.  There are also cases where one
+      #   wants to distribute .texi files, but does not want to
+      #   distribute the .info files.  For instance the Texinfo package
+      #   distributes the tool used to build these files; it would
+      #   be a waste of space to distribute them.  It's not clear
+      #   which syntax we should use to indicate that .info files should
+      #   not be distributed.  Akim Demaille suggested that eventually
+      #   we switch to a new syntax:
+      #   |  Maybe we should take some inspiration from what's already
+      #   |  done in the rest of Automake.  Maybe there is too much
+      #   |  syntactic sugar here, and you want
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  with a bit of magic to have bar.info represent the whole
+      #   |  bar*info set.  That's a lot more verbose that the current
+      #   |  situation, but it is # not new, hence the user has less
+      #   |  to learn.
+      #	  |
+      #   |  But there is still too much room for meaningless specs:
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     dist_PS = bar.ps something-written-by-hand.ps
+      #   |     nodist_bar_ps_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  here bar.texi is dist_ in line 2, and nodist_ in 4.
+      #
+      # Back to the point, it should be clear that in order to support
+      # non-distributed .info files, we need to build them in the
+      # build tree, not in the source tree (non-distributed .texi
+      # files are less of a problem, because we do not output build
+      # rules for them).  In Automake 1.7 .info build rules have been
+      # largely cleaned up so that .info files get always build in the
+      # build tree, even when distributed.  The idea was that
+      #   (1) if during a VPATH build the .info file was found to be
+      #       absent or out-of-date (in the source tree or in the
+      #       build tree), Make would rebuild it in the build tree.
+      #       If an up-to-date source-tree of the .info file existed,
+      #       make would not rebuild it in the build tree.
+      #   (2) having two copies of .info files, one in the source tree
+      #       and one (newer) in the build tree is not a problem
+      #       because 'make dist' always pick files in the build tree
+      #       first.
+      # However it turned out the be a bad idea for several reasons:
+      #   * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+      #     like GNU Make on point (1) above.  These implementations
+      #     of Make would always rebuild .info files in the build
+      #     tree, even if such files were up to date in the source
+      #     tree.  Consequently, it was impossible to perform a VPATH
+      #     build of a package containing Texinfo files using these
+      #     Make implementations.
+      #     (Refer to the Autoconf Manual, section "Limitation of
+      #     Make", paragraph "VPATH", item "target lookup", for
+      #     an account of the differences between these
+      #     implementations.)
+      #   * The GNU Coding Standards require these files to be built
+      #     in the source-tree (when they are distributed, that is).
+      #   * Keeping a fresher copy of distributed files in the
+      #     build tree can be annoying during development because
+      #     - if the files is kept under CVS, you really want it
+      #       to be updated in the source tree
+      #     - it is confusing that 'make distclean' does not erase
+      #       all files in the build tree.
+      #
+      # Consequently, starting with Automake 1.8, .info files are
+      # built in the source tree again.  Because we still plan to
+      # support non-distributed .info files at some point, we
+      # have a single variable ($INSRC) that controls whether
+      # the current .info file must be built in the source tree
+      # or in the build tree.  Actually this variable is switched
+      # off in two cases:
+      #  (1) For '.info' files that appear to be cleaned; this is for
+      #      backward compatibility with package such as Texinfo,
+      #      which do things like
+      #        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+      #        DISTCLEANFILES = texinfo texinfo-* info*.info*
+      #        # Do not create info files for distribution.
+      #        dist-info:
+      #      in order not to distribute .info files.
+      #  (2) When the undocumented option 'info-in-builddir' is given.
+      #      This is done to allow the developers of GCC, GDB, GNU
+      #      binutils and the GNU bfd library to force the '.info' files
+      #      to be generated in the builddir rather than the srcdir, as
+      #      was once done when the (now removed) 'cygnus' option was
+      #      given.  See automake bug#11034 for more discussion.

+#		  ## How `autoupdate' functions.  ##
+#		  ## ---------------------------- ##
+#
+# The task of `autoupdate' is not trivial: the biggest difficulty being
+# that you must limit the changes to the parts that really need to be
+# updated.  Finding a satisfying implementation proved to be quite hard,
+# as this is the fifth implementation of `autoupdate'.
+#
+# Below, we will use a simple example of an obsolete macro:
+#
+#     AU_DEFUN([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))])
+#     AC_DEFUN([NEW], [echo "sum($1) = $2"])
+#
+# the input file contains
+#
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Of course the expected output is
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2], [3])
+#     NEW([0, 0], [0])
+#
+#
+# # First implementation: sed
+# # =========================
+#
+# The first implementation was only able to change the name of obsolete
+# macros.
+#
+# The file `acoldnames.m4' defined the old names based on the new names.
+# It was simple then to produce a sed script such as:
+#
+#     s/OLD/NEW/g
+#
+# Updating merely consisted in running this script on the file to
+# update.
+#
+# This scheme suffers from an obvious limitation: that `autoupdate' was
+# unable to cope with new macros that just swap some of its arguments
+# compared to the old macro.  Fortunately, that was enough to upgrade
+# from Autoconf 1 to Autoconf 2.  (But I have no idea whether the
+# changes in Autoconf 2 were precisely limited by this constraint.)
+#
+#
+# # Second implementation: hooks
+# # ============================
+#
+# The version 2.15 of Autoconf brought a vast number of changes compared
+# to 2.13, so a solution was needed.  One could think of extending the
+# `sed' scripts with specialized code for complex macros.  However, this
+# approach is of course full of flaws:
+#
+# a. the Autoconf maintainers have to write these snippets, which we
+#    just don't want to,
+#
+# b. I really don't think you'll ever manage to handle the quoting of
+#    m4 with a sed script.
+#
+# To satisfy a., let's remark that the code which implements the old
+# features in term of the new feature is exactly the code which should
+# replace the old code.
+#
+# To answer point b, as usual in the history of Autoconf, the answer, at
+# least on the paper, is simple: m4 is the best tool to parse m4, so
+# let's use m4.
+#
+# Therefore the specification is:
+#
+#     I want to be able to tell Autoconf, well, m4, that the macro I
+#     am currently defining is an obsolete macro (so that the user is
+#     warned), and its code is the code to use when running autoconf,
+#     but that the very same code has to be used when running
+#     autoupdate.  To summarize, the interface I want is
+#     `AU_DEFUN(OLD-NAME, NEW-CODE)'.
+#
+#
+# Now for the technical details.
+#
+# When running autoconf, except for the warning, AU_DEFUN is basically
+# AC_DEFUN.
+#
+# When running autoupdate, we want *only* OLD-NAMEs to be expanded.
+# This obviously means that acgeneral.m4 and acspecific.m4 must not be
+# loaded.  Nonetheless, because we want to use a rich set of m4
+# features, m4sugar.m4 is needed.  Please note that the fact that
+# Autoconf's macros are not loaded is positive on two points:
+#
+# - we do get an updated `configure.ac', not a `configure'!
+#
+# - the old macros are replaced by *calls* to the new-macros, not the
+#   body of the new macros, since their body is not defined!!!
+#   (Whoa, that's really beautiful!).
+#
+# Additionally we need to disable the quotes when reading the input for
+# two reasons: first because otherwise `m4' will swallow the quotes of
+# other macros:
+#
+#     NEW([1, 2], 3)
+#     => NEW(1, 2, 3)
+#
+# and second, because we want to update the macro calls which are
+# quoted, i.e., we want
+#
+#     FOO([OLD(1, 2)])
+#     => FOO([NEW([1, 2], [3])])
+#
+# If we don't disable the quotes, only the macros called at the top
+# level would be updated.
+#
+# So, let's disable the quotes.
+#
+# Well, not quite: m4sugar.m4 still needs to use quotes for some macros.
+# Well, in this case, when running in autoupdate code, each macro first
+# reestablishes the quotes, expands itself, and disables the quotes.
+#
+# Thinking a bit more, you realize that in fact, people may use `define',
+# `ifelse' etc. in their files, and you certainly don't want to process
+# them.  Another example is `dnl': you don't want to remove the
+# comments.  You then realize you don't want exactly to import m4sugar:
+# you want to specify when it is enabled (macros active), and disabled.
+# m4sugar provides m4_disable/m4_enable to this end.
+#
+# You're getting close to it.  Now remains one task: how to handle
+# twofold definitions?
+#
+# Remember that the same AU_DEFUN must be understood in two different
+# ways, the AC way, and the AU way.
+#
+# One first solution is to check whether acgeneral.m4 was loaded.  But
+# that's definitely not cute.  Another is simply to install `hooks',
+# that is to say, to keep in some place m4 knows, late `define' to be
+# triggered *only* in AU mode.
+#
+# You first think of designing AU_DEFUN like this:
+#
+# 1. AC_DEFUN(OLD-NAME,
+#	      [Warn the user OLD-NAME is obsolete.
+#	       NEW-CODE])
+#
+# 2. Store for late AU binding([define(OLD_NAME,
+#				[Reestablish the quotes.
+#				 NEW-CODE
+#				 Disable the quotes.])])
+#
+# but this will not work: NEW-CODE probably uses $1, $2 etc. and these
+# guys will be replaced with the argument of `Store for late AU binding'
+# when you call it.
+#
+# I don't think there is a means to avoid this using this technology
+# (remember that $1 etc. are *always* expanded in m4).  You may also try
+# to replace them with $[1] to preserve them for a later evaluation, but
+# if `Store for late AU binding' is properly written, it will remain
+# quoted till the end...
+#
+# You have to change technology.  Since the problem is that `$1'
+# etc. should be `consumed' right away, one solution is to define now a
+# second macro, `AU_OLD-NAME', and to install a hook than binds OLD-NAME
+# to AU_OLD-NAME.  Then, autoupdate.m4 just need to run the hooks.  By
+# the way, the same method was used in autoheader.
+#
+#
+# # Third implementation: m4 namespaces by m4sugar
+# # ==============================================
+#
+# Actually, this implementation was just a clean up of the previous
+# implementation: instead of defining hooks by hand, m4sugar was equipped
+# with `namespaces'.  What are they?
+#
+# Sometimes we want to disable some *set* of macros, and restore them
+# later.  We provide support for this via namespaces.
+#
+# There are basically three characters playing this scene: defining a
+# macro in a namespace, disabling a namespace, and restoring a namespace
+# (i.e., all the definitions it holds).
+#
+# Technically, to define a MACRO in NAMESPACE means to define the macro
+# named `NAMESPACE::MACRO' to the VALUE.  At the same time, we append
+# `undefine(NAME)' in the macro named `m4_disable(NAMESPACE)', and
+# similarly a binding of NAME to the value of `NAMESPACE::MACRO' in
+# `m4_enable(NAMESPACE)'.  These mechanisms allow to bind the macro of
+# NAMESPACE and to unbind them at will.
+#
+# Of course this implementation is really inefficient: m4 has to grow
+# strings which can become quickly huge, which slows it significantly.
+#
+# In particular one should avoid as much as possible to use `define' for
+# temporaries.  Now that `define' has quite a complex meaning, it is an
+# expensive operations that should be limited to macros.  Use
+# `m4_define' for temporaries.
+#
+# Private copies of the macros we used in entering / exiting the m4sugar
+# namespace.  It is much more convenient than fighting with the renamed
+# version of define etc.
+#
+#
+#
+# Those two implementations suffered from serious problems:
+#
+# - namespaces were really expensive, and incurred a major performance
+#   loss on `autoconf' itself, not only `autoupdate'.  One solution
+#   would have been the limit the use of namespaces to `autoupdate', but
+#   that's again some complications on m4sugar, which really doesn't need
+#   this.  So we wanted to get rid of the namespaces.
+#
+# - since the quotes were disabled, autoupdate was sometimes making
+#   wrong guesses, for instance on:
+#
+#     foo([1, 2])
+#
+#   m4 saw 2 arguments: `[1'and `2]'.  A simple solution, somewhat
+#   fragile, is to reestablish the quotes right before all the obsolete
+#   macros, i.e., to use sed so that the previous text becomes
+#
+#     changequote([, ])foo([1, 2])
+#
+#   To this end, one wants to trace the definition of obsolete macros.
+#
+# It was there that the limitations of the namespace approach became
+# painful: because it was a complex machinery playing a lot with the
+# builtins of m4 (hence, quite fragile), tracing was almost impossible.
+#
+#
+# So this approach was dropped.
+#
+#
+# # The fourth implementation: two steps
+# # ====================================
+#
+# If you drop the uses of namespaces, you no longer can compute the
+# updated value, and replace the old call with it simultaneously.
+#
+# Obviously you will use m4 to compute the updated values, but you may
+# use some other tool to achieve the replacement.  Personally, I trust
+# nobody but m4 to parse m4, so below, m4 will perform the two tasks.
+#
+# How can m4 be used to replace *some* macros calls with newer values.
+# Well, that's dead simple: m4 should learn the definitions of obsolete
+# macros, forget its builtins, disable the quotes, and then run on the
+# input file, which amounts to doing this:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# which will result in
+#
+#     dnl The Unbelievable Truth
+#     NEW(1, 2, m4_eval(1 + 2))
+#     NEW([0, 0],
+#	  0)
+#
+# Grpmh.  Two problems.  A minor problem: it would have been much better
+# to have the `m4_eval' computed, and a major problem: you lost the
+# quotation in the result.
+#
+# Let's address the big problem first.  One solution is to define any
+# modern macro to rewrite its calls with the proper quotation, thanks to
+# `$@'.  Again, tracing the `define's makes it possible to know which
+# are these macros, so you input is:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
+#     define([NEW], [[NEW($@)]changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     changequote([, ])NEW([0, 0],
+#	  0)
+#
+# which results in
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2],[m4_eval(1 + 2)])
+#     NEW([0, 0],[0])
+#
+# Our problem is solved, i.e., the first call to `NEW' is properly
+# quoted, but introduced another problem: we changed the layout of the
+# second calls, which can be a drama in the case of huge macro calls
+# (think of `AC_TRY_RUN' for instance).  This example didn't show it,
+# but we also introduced parens to macros which did not have some:
+#
+#     AC_INIT
+#     => AC_INIT()
+#
+# No big deal for the semantics (unless the macro depends upon $#, which
+# is bad), but the users would not be happy.
+#
+# Additionally, we introduced quotes that were not there before, which is
+# OK in most cases, but could change the semantics of the file.
+#
+# Cruel dilemma: we do want the auto-quoting definition of `NEW' when
+# evaluating `OLD', but we don't when we evaluate the second `NEW'.
+# Back to namespaces?
+#
+# No.
+#
+#
+# # Second step: replacement
+# # ------------------------
+#
+# No, as announced above, we will work in two steps: in a first step we
+# compute the updated values, and in a second step we replace them.  Our
+# goal is something like this:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([1, 2], [3])changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# i.e., the new value of `OLD' is precomputed using the auto-quoting
+# definition of `NEW' and the m4 builtins.  We'll see how afterwards,
+# let's finish with the replacement.
+#
+# Of course the solution above is wrong: if there were other calls to
+# `OLD' with different values, we would smash them to the same value.
+# But it is quite easy to generalize the scheme above:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD([1],[2])], [NEW([1, 2], [3])])
+#     define([OLD], [defn([OLD($@)])changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# i.e., for each call to obsolete macros, we build an array `call =>
+# value', and use a macro to dispatch these values.  This results in:
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2], [3])
+#     NEW([0, 0],
+#	  0)
+#
+# In French, we say `Youpi !', which you might roughly translate as
+# `Yippee!'.
+#
+#
+# # First step: computation
+# # -----------------------
+#
+# Let's study the anatomy of the file, and name its sections:
+#
+# prologue
+#     divert(-1)dnl
+#     changequote([, ])
+# values
+#     define([OLD([1],[2])], [NEW([1, 2], [3])])
+# dispatcher
+#     define([OLD], [defn([OLD($@)])changequote()])
+# disabler
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+# input
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+#
+# # Computing the `values' section
+# # ..............................
+#
+# First we need to get the list of all the AU macro uses.  To this end,
+# first get the list of all the AU macros names by tracing `AU_DEFUN' in
+# the initialization of autoconf.  This list is computed in the file
+# `au.txt' below.
+#
+# Then use this list to trace all the AU macro uses in the input.  The
+# goal is obtain in the case of our example:
+#
+#     [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
+#
+# This is the file `values.in' below.
+#
+# We want to evaluate this with only the builtins (in fact m4sugar), the
+# auto-quoting definitions of the new macros (`new.m4'), and the
+# definition of the old macros (`old.m4').  Computing these last two
+# files is easy: it's just a matter of using the right `--trace' option.
+#
+# So the content of `values.in' is:
+#
+#     include($autoconf_dir/m4sugar.m4)
+#     m4_include(new.m4)
+#     m4_include(old.m4)
+#     divert(0)dnl
+#     [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
+#
+# We run m4 on it, which yields:
+#
+#     define([OLD([1],[2])],@<<@NEW([1, 2], [3])@>>@)
+#
+# Transform `@<<@' and `@>>@' into quotes and we get
+#
+#     define([OLD([1],[2])],[NEW([1, 2], [3])])
+#
+# This is `values.m4'.
+#
+#
+# # Computing the `dispatcher' section
+# # ..................................
+#
+# The `prologue', and the `disabler' are simple and need no commenting.
+#
+# To compute the `dispatcher' (`dispatch.m4'), again, it is a simple
+# matter of using the right `--trace'.
+#
+# Finally, the input is not exactly the input file, rather it is the
+# input file with the added `changequote'.  To this end, we build
+# `quote.sed'.
+#
+#
+# # Putting it all together
+# # .......................
+#
+# We build the file `input.m4' which contains:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     include(values.m4)
+#     include(dispatch.m4)
+#     undefine([dnl])
+#     undefine([eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# And we just run m4 on it.  Et voila`, Monsieur !  Mais oui, mais oui.
+#
+# Well, there are a few additional technicalities.  For instance, we
+# rely on `changequote', `ifelse' and `defn', but we don't want to
+# interpret the changequotes of the user, so we simply use another name:
+# `_au_changequote' etc.
+#
+#
+# # Failure of the fourth approach
+# # ------------------------------
+#
+# This approach is heavily based on traces, but then there is an obvious
+# problem: non expanded code will never be seen.  In particular, the body
+# of a `define' definition is not seen, so on the input
+#
+#	  define([idem], [OLD(0, [$1])])
+#
+# autoupdate would never see the `OLD', and wouldn't have updated it.
+# Worse yet, if `idem(0)' was used later, then autoupdate sees that
+# `OLD' is used, computes the result for `OLD(0, 0)' and sets up a
+# dispatcher for `OLD'.  Since there was no computed value for `OLD(0,
+# [$1])', the dispatcher would have replaced with... nothing, leading
+# to
+#
+#	  define([idem], [])
+#
+# With some more thinking, you see that the two step approach is wrong,
+# the namespace approach was much saner.
+#
+# But you learned a lot, in particular you realized that using traces
+# can make it possible to simulate namespaces!
+#
+#
+#
+# # The fifth implementation: m4 namespaces by files
+# # ================================================
+#
+# The fourth implementation demonstrated something unsurprising: you
+# cannot precompute, i.e., the namespace approach was the right one.
+# Still, we no longer want them, they're too expensive.  Let's have a
+# look at the way it worked.
+#
+# When updating
+#
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# you evaluate `input.m4':
+#
+#     divert(-1)
+#     changequote([, ])
+#     define([OLD],
+#     [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
+#     ...
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# where `m4_disable' undefines the m4 and m4sugar, and disables the quotes
+# and comments:
+#
+#     define([m4_disable],
+#     [undefine([__file__])
+#     ...
+#     changecom(#)
+#     changequote()])
+#
+# `m4_enable' does the converse: reestablish quotes and comments
+# --easy--, reestablish m4sugar --easy: just load `m4sugar.m4' again-- and
+# reenable the builtins.  This later task requires that you first save
+# the builtins.  And BTW, the definition above of `m4_disable' cannot
+# work: you undefined `changequote' before using it!  So you need to use
+# your privates copies of the builtins.  Let's introduce three files for
+# this:
+#
+#  `m4save.m4'
+#    moves the m4 builtins into the `_au_' pseudo namespace,
+#  `unm4.m4'
+#    undefines the builtins,
+#  `m4.m4'
+#    restores them.
+#
+# So `input.m4' is:
+#
+#     divert(-1)
+#     changequote([, ])
+#
+#     include([m4save.m4])
+#
+#     # Import AU.
+#     define([OLD],
+#     [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
+#
+#     define([_au_enable],
+#     [_au_changecom([#])
+#     _au_include([m4.m4])
+#     _au_include(m4sugar.m4)])
+#
+#     define([_au_disable],
+#     [# Disable m4sugar.
+#     # Disable the m4 builtins.
+#     _au_include([unm4.m4])
+#     # 1. Disable special characters.
+#     _au_changequote()
+#     _au_changecom()])
+#
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Based on what we learned in the fourth implementation we know that we
+# have to enable the quotes *before* any AU macro, and we know we need
+# to build autoquoting versions of the AC macros.  But the autoquoting
+# AC definitions must be disabled in the rest of the file, and enabled
+# inside AU macros.
+#
+# Using `autoconf --trace' it is easy to build the files
+#
+#   `ac.m4'
+#     define the autoquoting AC fake macros
+#   `disable.m4'
+#     undefine the m4sugar and AC autoquoting macros.
+#   `au.m4'
+#     definitions of the AU macros (such as `OLD' above).
+#
+# Now, `input.m4' is:
+#
+#     divert(-1)
+#     changequote([, ])
+#
+#     include([m4save.m4])
+#     # Import AU.
+#     include([au.m4])
+#
+#     define([_au_enable],
+#     [_au_changecom([#])
+#     _au_include([m4.m4])
+#     _au_include(m4sugar.m4)
+#     _au_include(ac.m4)])
+#
+#     define([_au_disable],
+#     [_au_include([disable.m4])
+#     _au_include([unm4.m4])
+#     # 1. Disable special characters.
+#     _au_changequote()
+#     _au_changecom()])
+#
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     _au_changequote([, ])OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Finally, version V is ready.
+#
+# Well... almost.
+#
+# There is a slight problem that remains: if an AU macro OUTER includes
+# an AU macro INNER, then _au_enable will be run when entering OUTER
+# and when entering INNER (not good, but not too bad yet).  But when
+# getting out of INNER, _au_disable will disable everything while we
+# were still in OUTER.  Badaboom.
+#
+# Therefore _au_enable and _au_disable have to be written to work by
+# pairs: each _au_enable pushdef's _au_enabled, and each _au_disable
+# popdef's _au_enabled.  And of course _au_enable and _au_disable are
+# effective when _au_enabled is *not* defined.
+#
+# Finally, version V' is ready.  And there is much rejoicing.  (And I
+# have free time again.  I think.  Yeah, right.)

+Usage: $0 [OPTION]... [TEMPLATE-FILE]
+
+Generate a configuration script from a TEMPLATE-FILE if given, or
+\`configure.ac' if present, or else \`configure.in'.  Output is sent
+to the standard output if TEMPLATE-FILE is given, else into
+\`configure'.
+
+Operation modes:
+  -h, --help                print this help, then exit

+  -o, --output=FILE         save output in FILE (stdout is the default)
+  -W, --warnings=CATEGORY   report the warnings falling in CATEGORY [syntax]
+
+Warning categories include:
+  \`cross'         cross compilation issues
+  \`obsolete'      obsolete constructs
+  \`syntax'        dubious syntactic constructs
+  \`all'           all the warnings
+  \`no-CATEGORY'   turn off the warnings on CATEGORY
+  \`none'          turn off all the warnings
+  \`error'         warnings are error

+# -----
+$help = "Usage: $0 [OPTION]... [FILES]
+
+Run GNU M4 on the FILES, avoiding useless runs.  Output the traces if tracing,
+the frozen file if freezing, otherwise the expansion of the FILES.
+
+If some of the FILES are named \`FILE.m4f\' they are considered to be M4
+frozen files of all the previous files (which are therefore not loaded).
+If \`FILE.m4f\' is not found, then \`FILE.m4\' will be used, together with
+all the previous files.
+
+Some files may be optional, i.e., will only be processed if found in the
+include path, but then must end in \`.m4?\';  the question mark is not part of
+the actual file name.
+
+Operation modes:
+  -h, --help               print this help, then exit
+  -V, --version            print version number, then exit
+  -v, --verbose            verbosely report processing
+  -d, --debug              don\'t remove temporary files
+  -o, --output=FILE        save output in FILE (defaults to \`-\', stdout)
+  -f, --force              don\'t rely on cached values
+  -W, --warnings=CATEGORY  report the warnings falling in CATEGORY
+  -l, --language=LANG      specify the set of M4 macros to use
+  -C, --cache=DIRECTORY    preserve results for future runs in DIRECTORY
+      --no-cache           disable the cache
+  -m, --mode=OCTAL         change the non trace output file mode (0666)
+  -M, --melt               don\'t use M4 frozen files
+
+Languages include:
+  \`Autoconf\'   create Autoconf configure scripts
+  \`Autotest\'   create Autotest test suites
+  \`M4sh\'       create M4sh shell scripts
+  \`M4sugar\'    create M4sugar output
+
+" . Autom4te::ChannelDefs::usage . "
+
+The environment variables \`M4\' and \`WARNINGS\' are honored.
+
+Library directories:
+  -B, --prepend-include=DIR  prepend directory DIR to search path
+  -I, --include=DIR          append directory DIR to search path
+
+Tracing:
+  -t, --trace=MACRO[:FORMAT]  report the MACRO invocations
+  -p, --preselect=MACRO       prepare to trace MACRO in a future run
+
+Freezing:
+  -F, --freeze   produce an M4 frozen state file for FILES
+
+FORMAT defaults to \`\$f:\$l:\$n:\$%\', and can use the following escapes:
+  \$\$     literal \$
+  \$f     file where macro was called
+  \$l     line where macro was called
+  \$d     nesting depth of macro call
+  \$n     name of the macro
+  \$NUM   argument NUM, unquoted and with newlines
+  \$SEP\@  all arguments, with newlines, quoted, and separated by SEP
+  \$SEP*  all arguments, with newlines, unquoted, and separated by SEP
+  \$SEP%  all arguments, without newlines, unquoted, and separated by SEP
+SEP can be empty for the default (comma for \@ and *, colon for %),
+a single character for that character, or {STRING} to use a string.

+      # non-distributed .info files, and non-distributed .texi
+      # files.
+      #
+      # * Non-distributed .texi files is important in some packages
+      #   where .texi files are built at make time, probably using
+      #   other binaries built in the package itself, maybe using
+      #   tools or information found on the build host.  Because
+      #   these files are not distributed they are always rebuilt
+      #   at make time; they should therefore not lie in the source
+      #   directory.  One plan was to support this using
+      #   nodist_info_TEXINFOS or something similar.  (Doing this
+      #   requires some sanity checks.  For instance Automake should
+      #   not allow:
+      #      dist_info_TEXINFOS = foo.texi
+      #      nodist_foo_TEXINFOS = included.texi
+      #   because a distributed file should never depend on a
+      #   non-distributed file.)
+      #
+      # * If .texi files are not distributed, then .info files should
+      #   not be distributed either.  There are also cases where one
+      #   wants to distribute .texi files, but does not want to
+      #   distribute the .info files.  For instance the Texinfo package
+      #   distributes the tool used to build these files; it would
+      #   be a waste of space to distribute them.  It's not clear
+      #   which syntax we should use to indicate that .info files should
+      #   not be distributed.  Akim Demaille suggested that eventually
+      #   we switch to a new syntax:
+      #   |  Maybe we should take some inspiration from what's already
+      #   |  done in the rest of Automake.  Maybe there is too much
+      #   |  syntactic sugar here, and you want
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  with a bit of magic to have bar.info represent the whole
+      #   |  bar*info set.  That's a lot more verbose that the current
+      #   |  situation, but it is # not new, hence the user has less
+      #   |  to learn.
+      #	  |
+      #   |  But there is still too much room for meaningless specs:
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     dist_PS = bar.ps something-written-by-hand.ps
+      #   |     nodist_bar_ps_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  here bar.texi is dist_ in line 2, and nodist_ in 4.
+      #
+      # Back to the point, it should be clear that in order to support
+      # non-distributed .info files, we need to build them in the
+      # build tree, not in the source tree (non-distributed .texi
+      # files are less of a problem, because we do not output build
+      # rules for them).  In Automake 1.7 .info build rules have been
+      # largely cleaned up so that .info files get always build in the
+      # build tree, even when distributed.  The idea was that
+      #   (1) if during a VPATH build the .info file was found to be
+      #       absent or out-of-date (in the source tree or in the
+      #       build tree), Make would rebuild it in the build tree.
+      #       If an up-to-date source-tree of the .info file existed,
+      #       make would not rebuild it in the build tree.
+      #   (2) having two copies of .info files, one in the source tree
+      #       and one (newer) in the build tree is not a problem
+      #       because 'make dist' always pick files in the build tree
+      #       first.
+      # However it turned out the be a bad idea for several reasons:
+      #   * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+      #     like GNU Make on point (1) above.  These implementations
+      #     of Make would always rebuild .info files in the build
+      #     tree, even if such files were up to date in the source
+      #     tree.  Consequently, it was impossible to perform a VPATH
+      #     build of a package containing Texinfo files using these
+      #     Make implementations.
+      #     (Refer to the Autoconf Manual, section "Limitation of
+      #     Make", paragraph "VPATH", item "target lookup", for
+      #     an account of the differences between these
+      #     implementations.)
+      #   * The GNU Coding Standards require these files to be built
+      #     in the source-tree (when they are distributed, that is).
+      #   * Keeping a fresher copy of distributed files in the
+      #     build tree can be annoying during development because
+      #     - if the files is kept under CVS, you really want it
+      #       to be updated in the source tree
+      #     - it is confusing that 'make distclean' does not erase
+      #       all files in the build tree.
+      #
+      # Consequently, starting with Automake 1.8, .info files are
+      # built in the source tree again.  Because we still plan to
+      # support non-distributed .info files at some point, we
+      # have a single variable ($INSRC) that controls whether
+      # the current .info file must be built in the source tree
+      # or in the build tree.  Actually this variable is switched
+      # off in two cases:
+      #  (1) For '.info' files that appear to be cleaned; this is for
+      #      backward compatibility with package such as Texinfo,
+      #      which do things like
+      #        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+      #        DISTCLEANFILES = texinfo texinfo-* info*.info*
+      #        # Do not create info files for distribution.
+      #        dist-info:
+      #      in order not to distribute .info files.
+      #  (2) When the undocumented option 'info-in-builddir' is given.
+      #      This is done to allow the developers of GCC, GDB, GNU
+      #      binutils and the GNU bfd library to force the '.info' files
+      #      to be generated in the builddir rather than the srcdir, as
+      #      was once done when the (now removed) 'cygnus' option was
+      #      given.  See automake bug#11034 for more discussion.

+      # non-distributed .info files, and non-distributed .texi
+      # files.
+      #
+      # * Non-distributed .texi files is important in some packages
+      #   where .texi files are built at make time, probably using
+      #   other binaries built in the package itself, maybe using
+      #   tools or information found on the build host.  Because
+      #   these files are not distributed they are always rebuilt
+      #   at make time; they should therefore not lie in the source
+      #   directory.  One plan was to support this using
+      #   nodist_info_TEXINFOS or something similar.  (Doing this
+      #   requires some sanity checks.  For instance Automake should
+      #   not allow:
+      #      dist_info_TEXINFOS = foo.texi
+      #      nodist_foo_TEXINFOS = included.texi
+      #   because a distributed file should never depend on a
+      #   non-distributed file.)
+      #
+      # * If .texi files are not distributed, then .info files should
+      #   not be distributed either.  There are also cases where one
+      #   wants to distribute .texi files, but does not want to
+      #   distribute the .info files.  For instance the Texinfo package
+      #   distributes the tool used to build these files; it would
+      #   be a waste of space to distribute them.  It's not clear
+      #   which syntax we should use to indicate that .info files should
+      #   not be distributed.  Akim Demaille suggested that eventually
+      #   we switch to a new syntax:
+      #   |  Maybe we should take some inspiration from what's already
+      #   |  done in the rest of Automake.  Maybe there is too much
+      #   |  syntactic sugar here, and you want
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  with a bit of magic to have bar.info represent the whole
+      #   |  bar*info set.  That's a lot more verbose that the current
+      #   |  situation, but it is # not new, hence the user has less
+      #   |  to learn.
+      #	  |
+      #   |  But there is still too much room for meaningless specs:
+      #   |     nodist_INFO = bar.info
+      #   |     dist_bar_info_SOURCES = bar.texi
+      #   |     dist_PS = bar.ps something-written-by-hand.ps
+      #   |     nodist_bar_ps_SOURCES = bar.texi
+      #   |     bar_texi_DEPENDENCIES = foo.texi
+      #   |  here bar.texi is dist_ in line 2, and nodist_ in 4.
+      #
+      # Back to the point, it should be clear that in order to support
+      # non-distributed .info files, we need to build them in the
+      # build tree, not in the source tree (non-distributed .texi
+      # files are less of a problem, because we do not output build
+      # rules for them).  In Automake 1.7 .info build rules have been
+      # largely cleaned up so that .info files get always build in the
+      # build tree, even when distributed.  The idea was that
+      #   (1) if during a VPATH build the .info file was found to be
+      #       absent or out-of-date (in the source tree or in the
+      #       build tree), Make would rebuild it in the build tree.
+      #       If an up-to-date source-tree of the .info file existed,
+      #       make would not rebuild it in the build tree.
+      #   (2) having two copies of .info files, one in the source tree
+      #       and one (newer) in the build tree is not a problem
+      #       because 'make dist' always pick files in the build tree
+      #       first.
+      # However it turned out the be a bad idea for several reasons:
+      #   * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+      #     like GNU Make on point (1) above.  These implementations
+      #     of Make would always rebuild .info files in the build
+      #     tree, even if such files were up to date in the source
+      #     tree.  Consequently, it was impossible to perform a VPATH
+      #     build of a package containing Texinfo files using these
+      #     Make implementations.
+      #     (Refer to the Autoconf Manual, section "Limitation of
+      #     Make", paragraph "VPATH", item "target lookup", for
+      #     an account of the differences between these
+      #     implementations.)
+      #   * The GNU Coding Standards require these files to be built
+      #     in the source-tree (when they are distributed, that is).
+      #   * Keeping a fresher copy of distributed files in the
+      #     build tree can be annoying during development because
+      #     - if the files is kept under CVS, you really want it
+      #       to be updated in the source tree
+      #     - it is confusing that 'make distclean' does not erase
+      #       all files in the build tree.
+      #
+      # Consequently, starting with Automake 1.8, .info files are
+      # built in the source tree again.  Because we still plan to
+      # support non-distributed .info files at some point, we
+      # have a single variable ($INSRC) that controls whether
+      # the current .info file must be built in the source tree
+      # or in the build tree.  Actually this variable is switched
+      # off in two cases:
+      #  (1) For '.info' files that appear to be cleaned; this is for
+      #      backward compatibility with package such as Texinfo,
+      #      which do things like
+      #        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+      #        DISTCLEANFILES = texinfo texinfo-* info*.info*
+      #        # Do not create info files for distribution.
+      #        dist-info:
+      #      in order not to distribute .info files.
+      #  (2) When the undocumented option 'info-in-builddir' is given.
+      #      This is done to allow the developers of GCC, GDB, GNU
+      #      binutils and the GNU bfd library to force the '.info' files
+      #      to be generated in the builddir rather than the srcdir, as
+      #      was once done when the (now removed) 'cygnus' option was
+      #      given.  See automake bug#11034 for more discussion.

+#		  ## How `autoupdate' functions.  ##
+#		  ## ---------------------------- ##
+#
+# The task of `autoupdate' is not trivial: the biggest difficulty being
+# that you must limit the changes to the parts that really need to be
+# updated.  Finding a satisfying implementation proved to be quite hard,
+# as this is the fifth implementation of `autoupdate'.
+#
+# Below, we will use a simple example of an obsolete macro:
+#
+#     AU_DEFUN([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))])
+#     AC_DEFUN([NEW], [echo "sum($1) = $2"])
+#
+# the input file contains
+#
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Of course the expected output is
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2], [3])
+#     NEW([0, 0], [0])
+#
+#
+# # First implementation: sed
+# # =========================
+#
+# The first implementation was only able to change the name of obsolete
+# macros.
+#
+# The file `acoldnames.m4' defined the old names based on the new names.
+# It was simple then to produce a sed script such as:
+#
+#     s/OLD/NEW/g
+#
+# Updating merely consisted in running this script on the file to
+# update.
+#
+# This scheme suffers from an obvious limitation: that `autoupdate' was
+# unable to cope with new macros that just swap some of its arguments
+# compared to the old macro.  Fortunately, that was enough to upgrade
+# from Autoconf 1 to Autoconf 2.  (But I have no idea whether the
+# changes in Autoconf 2 were precisely limited by this constraint.)
+#
+#
+# # Second implementation: hooks
+# # ============================
+#
+# The version 2.15 of Autoconf brought a vast number of changes compared
+# to 2.13, so a solution was needed.  One could think of extending the
+# `sed' scripts with specialized code for complex macros.  However, this
+# approach is of course full of flaws:
+#
+# a. the Autoconf maintainers have to write these snippets, which we
+#    just don't want to,
+#
+# b. I really don't think you'll ever manage to handle the quoting of
+#    m4 with a sed script.
+#
+# To satisfy a., let's remark that the code which implements the old
+# features in term of the new feature is exactly the code which should
+# replace the old code.
+#
+# To answer point b, as usual in the history of Autoconf, the answer, at
+# least on the paper, is simple: m4 is the best tool to parse m4, so
+# let's use m4.
+#
+# Therefore the specification is:
+#
+#     I want to be able to tell Autoconf, well, m4, that the macro I
+#     am currently defining is an obsolete macro (so that the user is
+#     warned), and its code is the code to use when running autoconf,
+#     but that the very same code has to be used when running
+#     autoupdate.  To summarize, the interface I want is
+#     `AU_DEFUN(OLD-NAME, NEW-CODE)'.
+#
+#
+# Now for the technical details.
+#
+# When running autoconf, except for the warning, AU_DEFUN is basically
+# AC_DEFUN.
+#
+# When running autoupdate, we want *only* OLD-NAMEs to be expanded.
+# This obviously means that acgeneral.m4 and acspecific.m4 must not be
+# loaded.  Nonetheless, because we want to use a rich set of m4
+# features, m4sugar.m4 is needed.  Please note that the fact that
+# Autoconf's macros are not loaded is positive on two points:
+#
+# - we do get an updated `configure.ac', not a `configure'!
+#
+# - the old macros are replaced by *calls* to the new-macros, not the
+#   body of the new macros, since their body is not defined!!!
+#   (Whoa, that's really beautiful!).
+#
+# Additionally we need to disable the quotes when reading the input for
+# two reasons: first because otherwise `m4' will swallow the quotes of
+# other macros:
+#
+#     NEW([1, 2], 3)
+#     => NEW(1, 2, 3)
+#
+# and second, because we want to update the macro calls which are
+# quoted, i.e., we want
+#
+#     FOO([OLD(1, 2)])
+#     => FOO([NEW([1, 2], [3])])
+#
+# If we don't disable the quotes, only the macros called at the top
+# level would be updated.
+#
+# So, let's disable the quotes.
+#
+# Well, not quite: m4sugar.m4 still needs to use quotes for some macros.
+# Well, in this case, when running in autoupdate code, each macro first
+# reestablishes the quotes, expands itself, and disables the quotes.
+#
+# Thinking a bit more, you realize that in fact, people may use `define',
+# `ifelse' etc. in their files, and you certainly don't want to process
+# them.  Another example is `dnl': you don't want to remove the
+# comments.  You then realize you don't want exactly to import m4sugar:
+# you want to specify when it is enabled (macros active), and disabled.
+# m4sugar provides m4_disable/m4_enable to this end.
+#
+# You're getting close to it.  Now remains one task: how to handle
+# twofold definitions?
+#
+# Remember that the same AU_DEFUN must be understood in two different
+# ways, the AC way, and the AU way.
+#
+# One first solution is to check whether acgeneral.m4 was loaded.  But
+# that's definitely not cute.  Another is simply to install `hooks',
+# that is to say, to keep in some place m4 knows, late `define' to be
+# triggered *only* in AU mode.
+#
+# You first think of designing AU_DEFUN like this:
+#
+# 1. AC_DEFUN(OLD-NAME,
+#	      [Warn the user OLD-NAME is obsolete.
+#	       NEW-CODE])
+#
+# 2. Store for late AU binding([define(OLD_NAME,
+#				[Reestablish the quotes.
+#				 NEW-CODE
+#				 Disable the quotes.])])
+#
+# but this will not work: NEW-CODE probably uses $1, $2 etc. and these
+# guys will be replaced with the argument of `Store for late AU binding'
+# when you call it.
+#
+# I don't think there is a means to avoid this using this technology
+# (remember that $1 etc. are *always* expanded in m4).  You may also try
+# to replace them with $[1] to preserve them for a later evaluation, but
+# if `Store for late AU binding' is properly written, it will remain
+# quoted till the end...
+#
+# You have to change technology.  Since the problem is that `$1'
+# etc. should be `consumed' right away, one solution is to define now a
+# second macro, `AU_OLD-NAME', and to install a hook than binds OLD-NAME
+# to AU_OLD-NAME.  Then, autoupdate.m4 just need to run the hooks.  By
+# the way, the same method was used in autoheader.
+#
+#
+# # Third implementation: m4 namespaces by m4sugar
+# # ==============================================
+#
+# Actually, this implementation was just a clean up of the previous
+# implementation: instead of defining hooks by hand, m4sugar was equipped
+# with `namespaces'.  What are they?
+#
+# Sometimes we want to disable some *set* of macros, and restore them
+# later.  We provide support for this via namespaces.
+#
+# There are basically three characters playing this scene: defining a
+# macro in a namespace, disabling a namespace, and restoring a namespace
+# (i.e., all the definitions it holds).
+#
+# Technically, to define a MACRO in NAMESPACE means to define the macro
+# named `NAMESPACE::MACRO' to the VALUE.  At the same time, we append
+# `undefine(NAME)' in the macro named `m4_disable(NAMESPACE)', and
+# similarly a binding of NAME to the value of `NAMESPACE::MACRO' in
+# `m4_enable(NAMESPACE)'.  These mechanisms allow to bind the macro of
+# NAMESPACE and to unbind them at will.
+#
+# Of course this implementation is really inefficient: m4 has to grow
+# strings which can become quickly huge, which slows it significantly.
+#
+# In particular one should avoid as much as possible to use `define' for
+# temporaries.  Now that `define' has quite a complex meaning, it is an
+# expensive operations that should be limited to macros.  Use
+# `m4_define' for temporaries.
+#
+# Private copies of the macros we used in entering / exiting the m4sugar
+# namespace.  It is much more convenient than fighting with the renamed
+# version of define etc.
+#
+#
+#
+# Those two implementations suffered from serious problems:
+#
+# - namespaces were really expensive, and incurred a major performance
+#   loss on `autoconf' itself, not only `autoupdate'.  One solution
+#   would have been the limit the use of namespaces to `autoupdate', but
+#   that's again some complications on m4sugar, which really doesn't need
+#   this.  So we wanted to get rid of the namespaces.
+#
+# - since the quotes were disabled, autoupdate was sometimes making
+#   wrong guesses, for instance on:
+#
+#     foo([1, 2])
+#
+#   m4 saw 2 arguments: `[1'and `2]'.  A simple solution, somewhat
+#   fragile, is to reestablish the quotes right before all the obsolete
+#   macros, i.e., to use sed so that the previous text becomes
+#
+#     changequote([, ])foo([1, 2])
+#
+#   To this end, one wants to trace the definition of obsolete macros.
+#
+# It was there that the limitations of the namespace approach became
+# painful: because it was a complex machinery playing a lot with the
+# builtins of m4 (hence, quite fragile), tracing was almost impossible.
+#
+#
+# So this approach was dropped.
+#
+#
+# # The fourth implementation: two steps
+# # ====================================
+#
+# If you drop the uses of namespaces, you no longer can compute the
+# updated value, and replace the old call with it simultaneously.
+#
+# Obviously you will use m4 to compute the updated values, but you may
+# use some other tool to achieve the replacement.  Personally, I trust
+# nobody but m4 to parse m4, so below, m4 will perform the two tasks.
+#
+# How can m4 be used to replace *some* macros calls with newer values.
+# Well, that's dead simple: m4 should learn the definitions of obsolete
+# macros, forget its builtins, disable the quotes, and then run on the
+# input file, which amounts to doing this:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# which will result in
+#
+#     dnl The Unbelievable Truth
+#     NEW(1, 2, m4_eval(1 + 2))
+#     NEW([0, 0],
+#	  0)
+#
+# Grpmh.  Two problems.  A minor problem: it would have been much better
+# to have the `m4_eval' computed, and a major problem: you lost the
+# quotation in the result.
+#
+# Let's address the big problem first.  One solution is to define any
+# modern macro to rewrite its calls with the proper quotation, thanks to
+# `$@'.  Again, tracing the `define's makes it possible to know which
+# are these macros, so you input is:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([$1, $2], m4_eval([$1 + $2]))changequote()])
+#     define([NEW], [[NEW($@)]changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     changequote([, ])NEW([0, 0],
+#	  0)
+#
+# which results in
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2],[m4_eval(1 + 2)])
+#     NEW([0, 0],[0])
+#
+# Our problem is solved, i.e., the first call to `NEW' is properly
+# quoted, but introduced another problem: we changed the layout of the
+# second calls, which can be a drama in the case of huge macro calls
+# (think of `AC_TRY_RUN' for instance).  This example didn't show it,
+# but we also introduced parens to macros which did not have some:
+#
+#     AC_INIT
+#     => AC_INIT()
+#
+# No big deal for the semantics (unless the macro depends upon $#, which
+# is bad), but the users would not be happy.
+#
+# Additionally, we introduced quotes that were not there before, which is
+# OK in most cases, but could change the semantics of the file.
+#
+# Cruel dilemma: we do want the auto-quoting definition of `NEW' when
+# evaluating `OLD', but we don't when we evaluate the second `NEW'.
+# Back to namespaces?
+#
+# No.
+#
+#
+# # Second step: replacement
+# # ------------------------
+#
+# No, as announced above, we will work in two steps: in a first step we
+# compute the updated values, and in a second step we replace them.  Our
+# goal is something like this:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD], [NEW([1, 2], [3])changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# i.e., the new value of `OLD' is precomputed using the auto-quoting
+# definition of `NEW' and the m4 builtins.  We'll see how afterwards,
+# let's finish with the replacement.
+#
+# Of course the solution above is wrong: if there were other calls to
+# `OLD' with different values, we would smash them to the same value.
+# But it is quite easy to generalize the scheme above:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     define([OLD([1],[2])], [NEW([1, 2], [3])])
+#     define([OLD], [defn([OLD($@)])changequote()])
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# i.e., for each call to obsolete macros, we build an array `call =>
+# value', and use a macro to dispatch these values.  This results in:
+#
+#     dnl The Unbelievable Truth
+#     NEW([1, 2], [3])
+#     NEW([0, 0],
+#	  0)
+#
+# In French, we say `Youpi !', which you might roughly translate as
+# `Yippee!'.
+#
+#
+# # First step: computation
+# # -----------------------
+#
+# Let's study the anatomy of the file, and name its sections:
+#
+# prologue
+#     divert(-1)dnl
+#     changequote([, ])
+# values
+#     define([OLD([1],[2])], [NEW([1, 2], [3])])
+# dispatcher
+#     define([OLD], [defn([OLD($@)])changequote()])
+# disabler
+#     undefine([dnl])
+#     undefine([m4_eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+# input
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+#
+# # Computing the `values' section
+# # ..............................
+#
+# First we need to get the list of all the AU macro uses.  To this end,
+# first get the list of all the AU macros names by tracing `AU_DEFUN' in
+# the initialization of autoconf.  This list is computed in the file
+# `au.txt' below.
+#
+# Then use this list to trace all the AU macro uses in the input.  The
+# goal is obtain in the case of our example:
+#
+#     [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
+#
+# This is the file `values.in' below.
+#
+# We want to evaluate this with only the builtins (in fact m4sugar), the
+# auto-quoting definitions of the new macros (`new.m4'), and the
+# definition of the old macros (`old.m4').  Computing these last two
+# files is easy: it's just a matter of using the right `--trace' option.
+#
+# So the content of `values.in' is:
+#
+#     include($autoconf_dir/m4sugar.m4)
+#     m4_include(new.m4)
+#     m4_include(old.m4)
+#     divert(0)dnl
+#     [define([OLD([1],[2])],]@<<@OLD([1],[2])@>>@[)]
+#
+# We run m4 on it, which yields:
+#
+#     define([OLD([1],[2])],@<<@NEW([1, 2], [3])@>>@)
+#
+# Transform `@<<@' and `@>>@' into quotes and we get
+#
+#     define([OLD([1],[2])],[NEW([1, 2], [3])])
+#
+# This is `values.m4'.
+#
+#
+# # Computing the `dispatcher' section
+# # ..................................
+#
+# The `prologue', and the `disabler' are simple and need no commenting.
+#
+# To compute the `dispatcher' (`dispatch.m4'), again, it is a simple
+# matter of using the right `--trace'.
+#
+# Finally, the input is not exactly the input file, rather it is the
+# input file with the added `changequote'.  To this end, we build
+# `quote.sed'.
+#
+#
+# # Putting it all together
+# # .......................
+#
+# We build the file `input.m4' which contains:
+#
+#     divert(-1)dnl
+#     changequote([, ])
+#     include(values.m4)
+#     include(dispatch.m4)
+#     undefine([dnl])
+#     undefine([eval])
+#     # Some more undefines...
+#     changequote()
+#     divert(0)dnl
+#     dnl The Unbelievable Truth
+#     changequote([, ])OLD(1, 2)
+#     NEW([0, 0],
+#	  0)
+#
+# And we just run m4 on it.  Et voila`, Monsieur !  Mais oui, mais oui.
+#
+# Well, there are a few additional technicalities.  For instance, we
+# rely on `changequote', `ifelse' and `defn', but we don't want to
+# interpret the changequotes of the user, so we simply use another name:
+# `_au_changequote' etc.
+#
+#
+# # Failure of the fourth approach
+# # ------------------------------
+#
+# This approach is heavily based on traces, but then there is an obvious
+# problem: non expanded code will never be seen.  In particular, the body
+# of a `define' definition is not seen, so on the input
+#
+#	  define([idem], [OLD(0, [$1])])
+#
+# autoupdate would never see the `OLD', and wouldn't have updated it.
+# Worse yet, if `idem(0)' was used later, then autoupdate sees that
+# `OLD' is used, computes the result for `OLD(0, 0)' and sets up a
+# dispatcher for `OLD'.  Since there was no computed value for `OLD(0,
+# [$1])', the dispatcher would have replaced with... nothing, leading
+# to
+#
+#	  define([idem], [])
+#
+# With some more thinking, you see that the two step approach is wrong,
+# the namespace approach was much saner.
+#
+# But you learned a lot, in particular you realized that using traces
+# can make it possible to simulate namespaces!
+#
+#
+#
+# # The fifth implementation: m4 namespaces by files
+# # ================================================
+#
+# The fourth implementation demonstrated something unsurprising: you
+# cannot precompute, i.e., the namespace approach was the right one.
+# Still, we no longer want them, they're too expensive.  Let's have a
+# look at the way it worked.
+#
+# When updating
+#
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# you evaluate `input.m4':
+#
+#     divert(-1)
+#     changequote([, ])
+#     define([OLD],
+#     [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
+#     ...
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# where `m4_disable' undefines the m4 and m4sugar, and disables the quotes
+# and comments:
+#
+#     define([m4_disable],
+#     [undefine([__file__])
+#     ...
+#     changecom(#)
+#     changequote()])
+#
+# `m4_enable' does the converse: reestablish quotes and comments
+# --easy--, reestablish m4sugar --easy: just load `m4sugar.m4' again-- and
+# reenable the builtins.  This later task requires that you first save
+# the builtins.  And BTW, the definition above of `m4_disable' cannot
+# work: you undefined `changequote' before using it!  So you need to use
+# your privates copies of the builtins.  Let's introduce three files for
+# this:
+#
+#  `m4save.m4'
+#    moves the m4 builtins into the `_au_' pseudo namespace,
+#  `unm4.m4'
+#    undefines the builtins,
+#  `m4.m4'
+#    restores them.
+#
+# So `input.m4' is:
+#
+#     divert(-1)
+#     changequote([, ])
+#
+#     include([m4save.m4])
+#
+#     # Import AU.
+#     define([OLD],
+#     [m4_enable()NEW([$1, $2], m4_eval([$1 + $2]))m4_disable()])
+#
+#     define([_au_enable],
+#     [_au_changecom([#])
+#     _au_include([m4.m4])
+#     _au_include(m4sugar.m4)])
+#
+#     define([_au_disable],
+#     [# Disable m4sugar.
+#     # Disable the m4 builtins.
+#     _au_include([unm4.m4])
+#     # 1. Disable special characters.
+#     _au_changequote()
+#     _au_changecom()])
+#
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Based on what we learned in the fourth implementation we know that we
+# have to enable the quotes *before* any AU macro, and we know we need
+# to build autoquoting versions of the AC macros.  But the autoquoting
+# AC definitions must be disabled in the rest of the file, and enabled
+# inside AU macros.
+#
+# Using `autoconf --trace' it is easy to build the files
+#
+#   `ac.m4'
+#     define the autoquoting AC fake macros
+#   `disable.m4'
+#     undefine the m4sugar and AC autoquoting macros.
+#   `au.m4'
+#     definitions of the AU macros (such as `OLD' above).
+#
+# Now, `input.m4' is:
+#
+#     divert(-1)
+#     changequote([, ])
+#
+#     include([m4save.m4])
+#     # Import AU.
+#     include([au.m4])
+#
+#     define([_au_enable],
+#     [_au_changecom([#])
+#     _au_include([m4.m4])
+#     _au_include(m4sugar.m4)
+#     _au_include(ac.m4)])
+#
+#     define([_au_disable],
+#     [_au_include([disable.m4])
+#     _au_include([unm4.m4])
+#     # 1. Disable special characters.
+#     _au_changequote()
+#     _au_changecom()])
+#
+#     m4_disable()
+#     dnl The Unbelievable Truth
+#     _au_changequote([, ])OLD(1, 2)
+#     NEW([0, 0], [0])
+#
+# Finally, version V is ready.
+#
+# Well... almost.
+#
+# There is a slight problem that remains: if an AU macro OUTER includes
+# an AU macro INNER, then _au_enable will be run when entering OUTER
+# and when entering INNER (not good, but not too bad yet).  But when
+# getting out of INNER, _au_disable will disable everything while we
+# were still in OUTER.  Badaboom.
+#
+# Therefore _au_enable and _au_disable have to be written to work by
+# pairs: each _au_enable pushdef's _au_enabled, and each _au_disable
+# popdef's _au_enabled.  And of course _au_enable and _au_disable are
+# effective when _au_enabled is *not* defined.
+#
+# Finally, version V' is ready.  And there is much rejoicing.  (And I
+# have free time again.  I think.  Yeah, right.)
