//
// UDPDaemon - an example console application that utilizes the WSJT-X
// messaging facility
//
// This application is only provided as a simple console application
// example to demonstrate the WSJT-X messaging facility. It allows
// the user to set the server details either as a unicast UDP server
// or, if a multicast group address is provided, as a multicast
// server. The benefit of the multicast server is that multiple
// servers can be active at once each receiving all WSJT-X broadcast
// messages and each able to respond to individual WSJT_X clients. To
// utilize the multicast group features each WSJT-X client must set
// the same multicast group address as the UDP server address for
// example 239.255.0.0 for a site local multicast group.
