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