077:         *       this program is running in is used for an application

079:         * The second thru fourth optional command line parameters are sound file names
080:         *    If not given, the default file names are:
081:         *       techno_machine.au

086:         * 
087:         *    Java Sound engine has been advertised to support the following 8- and 16-
