+ purpose = receive an audio stream
+ [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.
