/* A yet very simple syslog message generator
 * 
 * The purpose of this program is to provide a facility that enables
 * to generate complex traffic patterns for testing purposes. It still is
 * in its infancy, but hopefully will evolve.
 *
 * Note that this has been created as a stand-alone application because it
 * was considered useful to have it as a separate program. But it should still
 * be possible to call its class from any other program, specifically the debug
 * GUI.
