//The template class.....  Modify this class to make your own applet
//by Andy Harris, 4/4/97
//Based on JavaC 1.02  Uses OLD event model!!!
//Uses gridbag layout manager.
//NOTE:  this class is NOT intended to be compiled directly.  Use it as a template
//       for building your own classes.

  //especially components which will have events
