+#    Description:
+#      This file is the makefile for the GNU C++ Standard Library.
+#
+#      The following set of packages MUST be a matched set:
+#
+#	 * Target Binary Utilities
+#        * Target GNU C Standard Library
+#        * Target GNU C++ Standard Library
+#        * Target GDB server and client
+#	 * Host Cross Binary Utilities
+#	 * Host Cross Compilers
+#        * Host Cross GDB client
+#
+#      These are presumed provided by the tool chain and are simply
+#      sourced from it rather than built anew from source.
+#
+#      This is acceptable but a little less than ideal since it makes
+#      the build tree, specifically this make file, dependent on the tool
+#      chain in a non-abstracted way. Ideally, we'd like to be able to
+#      rebuild all the target pieces from source against any arbitrary
+#      tool chain meeting some minimum set of capabilities.
