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. | |
