   2 #
   3 # This script called in a CVS directory generates an archive in that
   4 # same directory, which contains all locally added new files (except
   5 # those rejected by the script) and a diff with all local changes.
   6 # This archive can then be offered to one of the CVS maintainers for
   7 # committing.
   8 #
   9 # Usage:
  10 #         $ cd $FG_ROOT/Aircraft/foo
  11 #         $ fg-submit      # generates foo.tar.bz2 and foo.diff
  12 #
  13 # The archive contains a copy of the diff, which is only left for
  14 # convenience and doesn't have to be submitted.
