This script demonstrates the various widgets provided by Tk, along with many of the features of the Tk toolkit. 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".
