   Bugs: should use getopt the way tar does (complete w/optional -) and
   should have long options too. GNU ar used to check file against filesystem
   in quick_update and replace operations (would check mtime). Doesn't warn
   when name truncated. No way to specify pos_end. Error messages should be
   more consistant.
