  1.00 | 03/01/99 | kjw | Initial Release.
------------------------------------------------------------------------------
  2.00 | 12/13/99 | kjw | nCrt is now a drop-in replacement for the standard
                        | FPC crt unit. All the previous OOP features have
                        | been moved to a new unit, oCrt (object crt).
                        | See oCrt.pp for a complete revision history.
