/* 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.
