udp_daemon does not serve any useful purpose other than to demonstrate the UDP message features of
       WSJT-X. It is a small command line application that interacts with any running WSJT-X instances.

       Developers writing add on applications may find the source code of udp_daemon contained in the WSJT-X
       code repository useful. The files NetworkMessage.hpp, MessageServer.hpp, MessageClient.hpp and their
       associated implementations along with the application source UDPDaemon.cpp should cover all the required
       areas. All these files can be found at:

       https://sourceforge.net/p/wsjt/wsjt/HEAD/tree/branches/wsjtx/

       udp_daemon may also be used as a multi-cast UDP server which allows multiple instances of udp_daemon to
       be run concurrently, to do this simply pass a suitable multi-cast group address using the command line
       option and in WSJT-X in the "Settings→Reporting→UDPServer" pane e.g. 239.255.0.1 or ff03::1 for a local
       scope group.

       Note that on some systems it may be necessary to add a static multi-cast route to the routing table
       before multi-cast traffic can be routed to sockets on the same host as the sender.
