+#
+# 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)
