- /* Extensions/incompatibilities:
- o - BSD output has filenames at the end.
- o - BSD output can appear in different radicies.
- o - SysV output has less redundant whitespace. Filename comes at end.
- o - SysV output doesn't show VMA which is always the same as the PMA.
- o - We also handle core files.
- o - We also handle archives.
- If you write shell scripts which manipulate this info then you may be
- out of luck; there's no --compatibility or --pedantic option.
