+#
+# DESCRIPTION
+#	Adjunct script for GNU CC to populate a directory with ANSI,
+#	Posix.1, and C++ compatible header files.
+#
+#	Each file found under each SOURCE-DIR is analized and "fixed."
+#	The SOURCE-DIRs are searched in order; a file found
+#	under multiple SOURCE-DIRs is only handled for the first one.
+#
+# STRATEGY
+#       Each include file is fed through cpp, and the scan-decls program
+#	parses it, and emits any found function declarations.
+#	The patch-header program analyzes the scan-decls output,
+#	together with the original include file, and writes a "fixed"
+#	include file, if needed.
+#
+#	The comment at the beginning of patch-header.c lists specifically
+#	what kind of changes are made.
+#
+# NOTE
+#	Some file space will be wasted, because the original header
+#	files are copied.  An earlier version just included the original
+#	by "reference", using GNU cpp's #include_next mechanism.
+#	This is currently not done, partly because #include_next is
+#	fragile (susceptible to version incompatibilties, and depends
+#	and GCC-specific features), and partly for performance reasons.
+#
+# AUTHORS
+#	Ron Guilmette (rfg@netcom.com) (original idea and code)
+#	Per Bothner (bothner@cygnus.com) (major re-write)
