Title:   mpd And icecast setup
Subject: How To setup streaming audio with Music Player Daemon and Icecast on gentoo.
#-----------------------------------------------------------------------
# MPD will have some local storage of music in /mpd/music
# MPD will be configured with 2 audio_output secions
#             one will output to locally attached speakers
#             one will output to a stream managed by icecast called /mpd.ogg
# Icecast will stream data sent to mpd.ogg to anyone listening for the stream
# Client player will tune into the the stream via: http://host:8000/mpd.ogg
# Note: mpd.ogg doesn't really exist.
# Note: when the stream ends, static.ogg will startplayin so that the stream doesn't end.
#----------------------------------------------------------------------
#
# Set mpd use flags
