 with this set to 50000, but not all devices support values this high.  Most
 users do not need to change this.  The default is 256000000 / sample_rate(kHz),
 or 5804 microseconds for CD-quality audio.
-.SH OPTIONAL OSS OUTPUT PARAMETERS
-.TP
-.B device <dev>
-This specifies the device to use for audio output.  The default is "/dev/dsp".
-.TP
-.B mixer_device <mixer dev>
-This specifies which mixer to use.  The default is "/dev/mixer".
-.TP
-.B mixer_control <mixer ctrl>
-This specifies which mixer control to use (sometimes referred to as the
-"device").  The default is to use the main PCM mixer.  An example is "Pcm".
-.SH OPTIONAL PULSE OUTPUT PARAMETERS
-.TP
-.B server <server list>
-A space separated list of servers to try to connect to.  See
-<\fBhttp://www.pulseaudio.org/wiki/ServerStrings\fP> for more details.  The
-default is to let PulseAudio choose a server.
-If you specify more than one server name, MPD tries to connect to one
-after another until it successfully establishes a connection.
-.TP
-.B sink <sink>
-The sink to output to.  The default is to let PulseAudio choose a sink.
-.SH OPTIONAL JACK OUTPUT PARAMETERS
-.TP
-.B client_name <name>
-The client name to use when connecting to JACK.  The output ports <name>:left
-and <name>:right will also be created for the left and right channels,
-respectively.
-.TP
-.B ports <left_port,right_port>
-This specifies the left and right ports to connect to for the left and right
-channels, respectively.  The default is to let JACK choose a pair of ports.
-.TP
-.B ringbuffer_size <size in bytes>
-This specifies the size of the ringbuffer in bytes.  The default is 32768.
-.SH OPTIONAL AO OUTPUT PARAMETERS
-.TP
-.B driver <driver>
-This specifies the libao driver to use for audio output.  Possible values
-depend on what libao drivers are available.  See
-<\fBhttp://www.xiph.org/ao/doc/drivers.html\fP> for information on some
-commonly used drivers.  Typical values for Linux include "oss" and "alsa09".
-The default is "default", which causes libao to select an appropriate plugin.
-.TP
-.B options <opts>
-This specifies the options to use for the selected libao driver.  For oss, the
-only option available is "dsp".  For alsa09, the available options are: "dev",
-"buf_size", and "periods".  See <\fBhttp://www.xiph.org/ao/doc/drivers.html\fP>
-for available options for some commonly used drivers.  Options are assigned
-using "=", and ";" is used to separate options.  An example for oss:
-"dsp=/dev/dsp".  An example for alsa09: "dev=hw:0,0;buf_size=4096".  The
-default is "".
-.TP
-.B write_size <size in bytes>
-This specifies how many bytes to write to the audio device at once.  This
-parameter is to work around a bug in older versions of libao on sound cards
-with very small buffers.  The default is 1024.
-.SH REQUIRED FIFO OUTPUT PARAMETERS
-.TP
-.B path <path>
-This specifies the path of the FIFO to output to.  Must be an absolute path.
-If the path does not exist it will be created when mpd is started, and removed
-when mpd is stopped.  The FIFO will be created with the same user and group as
-mpd is running as.  Default permissions can be modified by using the builtin
-shell command "umask".  If a FIFO already exists at the specified path it will
-be reused, and will \fBnot\fP be removed when mpd is stopped.  You can use the
-"mkfifo" command to create this, and then you may modify the permissions to
-your liking.
-.SH REQUIRED SHOUT OUTPUT PARAMETERS
-.TP
-.B name <name>
-This specifies not only the unique audio output name, but also the stream
-title.
-.TP
-.B host <hostname>
-This specifies the hostname of the icecast server to connect to.
-.TP
-.B port <port>
-This specifies the port of the icecast server to connect to.
-.TP
-.B mount <mountpoint>
-This specifies the icecast mountpoint to use.
-.TP
-.B password <password>
-This specifies the password to use when logging in to the icecast server.
-.TP
-.B quality <quality>
-This specifies the encoding quality to use.  The value must be between 0
-and 10.  Fractional values, such as 2.5, are permitted.  Either the quality or
-the bitrate parameter must be specified, but not both.  For Ogg, a
-higher quality number produces higher quality output.  For MP3, it's
-just the opposite, with lower numbers producing higher quality output.
-.TP
-.B bitrate <kbps>
-This specifies the bitrate to use for encoding.  Either the quality or the
-bitrate parameter must be specified, but not both.
-.TP
-.B format <sample_rate:bits:channels>
-This specifies the sample rate, bits per sample, and number of channels to use
-for encoding.
-.SH OPTIONAL SHOUT OUTPUT PARAMETERS
-.TP
-.B encoding <encoding>
-This specifies which output encoding to use.  Should be either "ogg"
-or "mp3",  "mp3" is needed for shoutcast streaming. The default is "ogg".
-.TP
-.B protocol <protocol>
-This specifies the protocol that wil be used to connect to the
-icecast/shoutcast server. The options are "shoutcast", "icecast1" and
-"icecast2". The default is "icecast2".
-.TP
-.B user <username>
-This specifies the username to use when logging in to the icecast server.  The
-default is "source".
-.TP
-.B public <yes or no>
