+       [description]
+               para_recv starts one paraslash receiver (http, dccp, udp or afh)
+               to produce an audio stream in the same way para_audiod would download
+               the stream from para_server (http, dccp or udp) or para_server makes a
+               stream out of an audio file (afh). This is mostly useful for debugging.
+
+               Regardless of which receiver was started, the audio stream is written
+               to stdout.
