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