# Generate list of objects for a given model library
# Variables:
#	name		  (library name, e.g., "ncurses", "panel", "forms", "menus")
#	traces		  ("all" or "DEBUG", to control whether tracing is compiled in)
#	MODEL		  (e.g., "DEBUG", uppercase; toupper is not portable)
#	CXX_MODEL	  (e.g., "DEBUG", uppercase)
#	model		  (directory into which we compile, e.g., "obj")
#	prefix		  (e.g., "lib", for Unix-style libraries)
#	suffix		  (e.g., "_g.a", for debug libraries)
#	subset		  ("none", "base", "base+ext_funcs" or "termlib", etc.)
#	driver		  ("yes" or "no", depends on --enable-term-driver)
#	ShlibVer	  ("rel", "abi" or "auto", to augment DoLinks variable)
#	ShlibVerInfix ("yes" or "no", determines location of version #)
#	SymLink		  ("ln -s", etc)
#	TermlibRoot	  ("tinfo" or other root for libterm.so)
#	TermlibSuffix (".so" or other suffix for libterm.so)
#	ReLink		  ("yes", or "no", flag to rebuild shared libs on install)
#	DoLinks		  ("yes", "reverse" or "no", flag to add symbolic links)
#	rmSoLocs	  ("yes" or "no", flag to add extra clean target)
#	ldconfig	  (path for this tool, if used)
#	overwrite	  ("yes" or "no", flag to add link to libcurses.a
#	depend		  (optional dependencies for all objects, e.g, ncurses_cfg.h)
#	host		  (cross-compile host, if any)
#	libtool_version (libtool "-version-info" or "-version-number")
#
# Notes:
#	CLIXs nawk does not like underscores in command-line variable names.
#	Mixed-case variable names are ok.
#	HP/UX requires shared libraries to have executable permissions.
