This file only contains code to -generate the main window for the application, which invokes individual -demonstrations. The code for the actual demonstrations is contained in -separate ".pl" files in the "widget_lib" directory, which are autoloaded -by this script as needed. - -widget looks in the directory specified on the command line to load user -contributed demonstrations. If no directory name is specified when widget is -invoked and the environment variable WIDTRIB is defined then demonstrations -are loaded from the WIDTRIB directory. If WIDTRIB is undefined then widget -defaults to the released user contributed directory, "widtrib". - -=head2 History - - # - # Stephen O. Lidie, LUCC, 96/03/11. lusol@Lehigh.EDU - # Stephen O.
