+.SH NAME
+mpd.conf \- Music Player Daemon configuration file
+.SH DESCRIPTION
+\fBmpd.conf\fP is the configuration file for mpd(1).  If not specified on the
+command line, MPD first searches for it at \fB~/.mpdconf\fP and then in
+\fB/etc/mpd.conf\fP.
+
+Lines beginning with a "#" character are comments.  All other non-empty lines
+specify parameters and their values.  These lines contain the parameter name
+and parameter value (surrounded by double quotes) separated by whitespace
+(either tabs or spaces).  For example:
+
+parameter "value"
+
+The exception to this rule is the audio_output parameter, which is of the form:
+
+audio_output {
+.br
+        parameter1 "value"
+        parameter2 "value"
+.br
+}
+
+Parameters that take a file or directory as an argument should use absolute
+paths.
+
+See \fBdocs/mpdconf.example\fP in the source tarball for an example
+configuration file.
+.SH REQUIRED PARAMETERS
+.TP
+.B music_directory <directory>
+This specifies the directory where music is located.
+.TP
+.B playlist_directory <directory>
+This specifies the directory where saved playlists are stored.
+.TP
+.B db_file <file>

+.SH OPTIONAL PARAMETERS
+.TP
+.B state_file <file>
+This specifies if a state file is used and where it is located.  The state of
+mpd will be saved to this file when mpd is terminated by a TERM signal or by
+the "kill" command.  When mpd is restarted, it will read the state file and

+PARAMETERS\fP.
+.TP
+.B audio_output_format <sample_rate:bits:channels>
+This specifies the sample rate, bits per sample, and number of channels of
+audio that is sent to each audio output.  Note that audio outputs may specify
+their own audio format which will be used for actual output to the audio
+device.  An example is "44100:16:2" for 44100Hz, 16 bits, and 2 channels.  The
+default is to use the audio format of the input file.
+.TP
+.B mixer_type <oss, alsa or software>
+This specifies which mixer to use.  The default depends on what audio output
+support mpd was built with.
+.TP
+.B mixer_device <mixer dev>
+This specifies which mixer to use.  The default for oss is "/dev/mixer"; the
+default for alsa is "default".
+.TP
+.B mixer_control <mixer ctrl>
+This specifies which mixer control to use (sometimes referred to as the
+"device").  Examples of mixer controls are PCM, Line1, Master, etc.  An example
+for OSS is "Pcm", and an example for alsa is "PCM".
+.TP
+.B filesystem_charset <charset>
+This specifies the character set used for the filesystem.  A list of supported
+character sets can be obtained by running "iconv -l".  The default is
+determined from the locale when the db was originally created.
+.TP
+.B replaygain <album or track>
+If specified, mpd will adjust the volume of songs played using replaygain tags
+(see <\fBhttp://www.replaygain.org/\fP>).  Setting this to "album" will adjust
+volume using the album's replaygain tags, while setting it to "track" will
+adjust it using the track replaygain tags.  Currently only FLAC, Ogg Vorbis,
+Musepack, and MP3 (through ID3v2 replaygain tags, not APEv2) are supported.

+.TP
+.B port <port>
+This specifies the port that mpd listens on.  The default is 6600.

+.B password <password@permissions>
+This specifies a password for access to mpd.  The format is
+"password@permissions" where permissions is a comma delimmitted list composed
