+# NAME:
+#      fixcpp - fix CPP errors
+#
+# SYNOPSIS:
+#      fixcpp [-c][-p patch_file][-b bak_dir][-n new_dir] files(s)
+#
+# DESCRIPTION:
+#      For each named file, use sed(1) to fixup any descriptive
+#      text after #else or #endif or that is not properly
+#      commented as this causes ANSI compilers to generate
+#      unnecessary warnings.
+#
+#      Naturally this script is not guaranteed to be bullet
+#      proof, use of -n or -b is advisable!
+#
+#      -c causes fixcpp to make sure that only files that
+#      needed changing are affected by returning the original
+#      file to its original location if no changes were needed.
+#
+#      -p causes fixcpp to append to a patch file the context
+#      diffs of the changes wrought.
+#
+# SEE ALSO:
+#      sed(1)
