  2.  * CAcurSwitchboard.c
  3.  * A useful supplement to CAnimCursor, when using the TCL.
  4.  * Version 1.0b3, 13 May 1992
  5.  *
  6.  * To use, change your application's MakeSwitchboard() method to:
  7.  *
  8.  *        void CYourApp::MakeSwitchboard(void)
  9.  *        {
  10.  *            itsSwitchboard = new(CAcurSwitchboard);
  11.  *            ((CAcurSwitchboard*)itsSwitchboard)->IAcurSwitchboard();
  12.  *        }
  13.  *
  14.  * If the switchboard you're presently using is not the standard
  15.  * CSwitchboard, see the note about multiple inheritance in
  16.  * CDesktop.c.
