  Rev 1.6    10/26/2004 9:36:30 PM  JPMugaas
  Updated ref.

  Rev 1.5    4/19/2004 5:05:30 PM  JPMugaas
  Class rework Kudzu wanted.

  Rev 1.4    2004.02.03 5:45:22 PM  czhower
  Name changes

  Rev 1.3    11/26/2003 6:22:24 PM  JPMugaas
  IdFTPList can now support file creation time for MLSD servers which support
  that feature.  I also added support for a Unique identifier for an item so
  facilitate some mirroring software if the server supports unique ID with EPLF
  and MLSD.

  Rev 1.2    10/19/2003 2:27:14 PM  DSiders
  Added localization comments.

  Rev 1.1    4/7/2003 04:03:48 PM  JPMugaas
  User can now descover what output a parser may give.

  Rev 1.0    2/19/2003 04:18:16 AM  JPMugaas
  More things restructured for the new list framework.
