23 | Bugs: should use getopt the way tar does (complete w/optional -) and | |
24 | should have long options too. GNU ar used to check file against filesystem | |
25 | in quick_update and replace operations (would check mtime). Doesn't warn | |
26 | when name truncated. No way to specify pos_end. Error messages should be | |
50c2245b | 27 | more consistent. */ |
