SHOUTcast Radio Transcoder

sc_trans operates in one of two modes, either reading mp3s off disk, decoding, re-encoding, and then broadcasting them, or relaying from a shoutcast server, transcoding to a lower bitrate, and broadcasting to a new server.

sc_trans accepts the following signals:
; HUP - flush logfiles (close and reopen) -- will make console logging stop
; WINCH - jump to next song
; USR1 - reload playlist off disk (will not interrupt current playing stream)
; USR2 - toggle shuffle on/off
; TERM - normal sc_trans shutdown (clean)
