 *
 * This class is intended for programmers and provides functions for some
 * common tasks like:
 *                     - Adding dialogs as frame controls to WPS folders
 *                     - Showing 'About'-dialogs
 *                     - Checking of object pointers
 *                     - ...
 *
 * Use IBM VAC++ V3.00 and Gnu-make 3.74.1 to compile
 *
