   3 # NAME:
   4 #       fixcpp - fix CPP errors
   5 #
   6 # SYNOPSIS:
   7 #       fixcpp [-c][-p patch_file][-b bak_dir][-n new_dir] files(s)
   8 #
   9 # DESCRIPTION:
  10 #       For each named file, use sed(1) to fixup any descriptive
  11 #       text after #else or #endif or that is not properly
  12 #       commented as this causes ANSI compilers to generate
  13 #       unnecessary warnings.
  14 #
  15 #       Naturally this script is not guaranteed to be bullet
  16 #       proof, use of -n or -b is advisable!
  17 #
  18 #       -c causes fixcpp to make sure that only files that
  19 #       needed changing are affected by returning the original
  20 #       file to its original location if no changes were needed.
  21 #
  22 #       -p causes fixcpp to append to a patch file the context
  23 #       diffs of the changes wrought.
  24 #
  25 # SEE ALSO:
  26 #       sed(1)
