  Rev 1.0    11/13/2002 08:29:48 AM  JPMugaas
  Initial import from FTP VC.

  2000-June- 9  J. Peter Mugaas
    -adjusted the Gopher+ support so that line-unfolding is disabled in
    FGopherBlock.  Many headers we use start with spaces
    -made the ASK block into a TIdHeaderList to facilitate use better.  This does
    unfold lines

  2000-May -24  J. Peter Mugaas
    -changed interface of file retrieval routines to so DestStream property does
    not have to even exist now.

  2000-May -17  J. Peter Mugaas
    -Optimized the DoneSettingInfoBlock method in the TIdGopherMenuItem object
    -Added Ask property to the TIdGopherMenuItem

  2000-May -13  J. Peter Mugaas
    -Chanded the event types and classes to be prefixed with Id.

  2000-Apr.-28  J. Peter Mugaas
    -Added built in Gopher+ support

  2000-Apr.-21  J. Peter Mugaas
    -Added the ability to receive a file
    -Restructured this component to make the code more reabible,
    facilitate processing, and improve object orientation

  2000-Apr.-20  J. Peter Mugaas
    -Started this unit
