  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.  */
