  Added localization comments.

  Rev 1.7    2003.10.18 9:42:08 PM  czhower
  Boatload of bug fixes to command handlers.

  Rev 1.6    8/2/2003 05:03:46 AM  JPMugaas
  Hopefully should now support IRCS (IRC over TLS/SSL)

  Rev 1.5    7/18/2003 4:26:30 PM  SPerry
  New IRC server using command handlers

  Rev 1.4    2/24/2003 09:07:18 PM  JPMugaas

  Rev 1.3    1/17/2003 07:10:36 PM  JPMugaas
  Now compiles under new framework.

  Rev 1.2    1-1-2003 20:13:22  BGooijen
  Changed to support the new TIdContext class

  Rev 1.1    12/7/2002 06:43:02 PM  JPMugaas
  These should now compile except for Socks server.  IPVersion has to be a
  property someplace for that.
