# exit with error in case mpd.conf does not define an audio_output like:
#
# cat <<EOT >>/etc/mpd.conf
# audio_output {
#        type            "pulse"
#        name            "My Pulse Output"
# }
# EOT

    then
        cat >&2 <<EOT
/etc/mpd.conf specifies the user MPD will run as.  Do not use this option if
you start MPD as an unprivileged user.  Please comment out the line starting
with 'user' and rerun this script.
