 *
 * Due to the limitations of PHP4 and PHP-Gtk, this class can not

 * - Reloading the class for each run
 * - Stopping the test in progress
 *
 * To use simply intantiate the class and call main()
 * $gtk =& new PHPUnit_GUI_Gtk;
 * $gtk->main();
 *
 * Once the window has finished loading, you can enter the name of
 * a class that has been loaded (include/require some where in your
 * code, or you can pass the name of the file containing the class.
 *
 * You can also load classes using the SetupDecorator class.
