<h2 class="chapter">1 Introduction</h2>
<a name="index-introduction"></a>
<p>Emms is the Emacs Multi-Media System. It tries to be a clean and small
application to play multimedia files from Emacs using external
players. Many of its ideas are derived from
<a href="http://www.nongnu.org/mp3player">MpthreePlayer</a>, but it tries to
be more general and more clean.
</p>
<p>This manual tries to be the definitive source of information about
Emms, an online version of the manual is available at:
<a href="http://www.gnu.org/software/emms/manual/">http://www.gnu.org/software/emms/manual/</a>.
</p>
<p>The basic functionality of Emms consists of three parts: The core, the
sources, and the players.
</p>
<p>The core resides in <samp>emms.el</samp>, and provides a simple playlist and the
basic functionality to use all the other features of Emms. It provides
the common user commands and interfaces for other parts. It thinks in
tracks, where a track is the combination of a type and a name - e.g.
the track type ’file has a name that is the file name. Other track
types are possible.
</p>
<p>To get to tracks, the core needs sources. The file <samp>emms-source-file.el</samp>
provides simple sources to interact with the file system.
</p>
<p>When Emms finally has the sources in the playlist, it needs a player
to play them. <samp>emms-player-simple.el</samp> defines a few useful players, and
allows you to define your own in a very simple way.
</p>
<p>The Emms core comes with many additional features to extend its
functionality.
</p>
<p>The way Emms works is easy to customize with your own code or by using
‘M-x customize’ or by changing the variables directly.

<a name="Quickstart-Guide-1"></a>
<h2 class="chapter">2 Quickstart Guide</h2>
<p>This chapter demonstrates how to setup Emms so that you can start
listening to your music without having to read all of the
documentation first. This is the tl;dr version of the manual.
</p>
<p>The first thing you have to do is telling Emacs where Emms is
located. Let’s say you have it in <samp>~/elisp/emms/</samp>. So add this
line to your <samp>.emacs</samp>:
</p>
<div class="lisp">
<pre class="lisp">(add-to-list 'load-path "~/elisp/emms/lisp/")
</pre></div>
<p>More detailed information about installing Emms can be found in the
installation chapter, See <a href="#Installation">Installation</a>.
</p>
<p>You’ll then want to load Emms into Emacs. To achieve this you invoke
the <code>emms-all</code> setup function by adding the following three lines
to your <samp>.emacs</samp>.
</p>
<div class="lisp">
<pre class="lisp">(require 'emms-setup)
(emms-all)
(emms-default-players)
</pre></div>
<p>The function <code>emms-default-players</code> in the last line sets up the
list of default players. The list contains lightweight specialized
players like ogg123 or mpg321 and we-play-everything-players such as
mplayer, vlc, etc.. To be sure that emms can play all your music you
should check that your preferred players are installed on the machine.
</p>
<p>More detail about setting up Emms can be found in the setup chapter,
See <a href="#Setup">Setup</a>.
</p>
<p>Emms tries to display the tags (the name of the song, as opposed to
the name of the file) of the music you listen to. Emms can use libtag,
see See <a href="#Using-TagLib">Using TagLib</a>, or a combination of ‘mp3info’ and ‘ogginfo’
(make sure that they are installed if you want Emms to use them.)
</p>
<p>The last thing to do is to tell Emms where your music is; the root
directory of our music collection. Let’s say all your music is in
<samp>~/Music</samp> or in subdirectories thereof.
</p>
<div class="lisp">
<pre class="lisp">(setq emms-source-file-default-directory "~/Music/")
</pre></div>
<p>OK, now we’ve set up Emms. Reload your <samp>.emacs</samp> or restart Emacs to
let the changes have an effect.
</p>
<p>Now we will add all our music to a playlist by invoking <kbd>M-x
emms-add-directory-tree RET ~/Music/ RET</kbd>. We do this because then
Emms will read the tags of all your music files and caches them (this
is also required for the Emms browser, See <a href="#The-Browser">The Browser</a>.)
</p>
<p>To switch to the playlist buffer, invoke <kbd>M-x
emms-playlist-mode-go</kbd> or simply <kbd>M-x emms</kbd>. You may see that some
tracks are displayed with their file name, but as Emms populates its
tag cahe, track by track, the filenames get replaced with the artist
and track name of the file’s tag.
</p>
<p>Go ahead and navigate to a track and hit <kbd>RET</kbd> on it to start
playback.
</p>
<p>Now you can start exploring Emms. It’s probably best to begin with the
basic commands (see <a href="#Basic-Commands">Basic Commands</a>), the interactive playlists
(see <a href="#Interactive-Playlists">Interactive Playlists</a>), and the browser (see <a href="#The-Browser">The Browser</a>).

</p>
<p><code>make</code>
</p>
<p>Which will byte compile Emms. You can then invoke:
</p>
<p><code>make install</code>
</p>
<p>Which will install Emms into your Emacs directories (provided you have
the appropriate permissions to do so on your system).
</p>
<p>Note that Emms is a light-weight and agile program, you can therefore
run Emms just fine without byte compiling it.

<p>The ‘emms-setup’ feature is provided by the file
<samp>emms-setup.el</samp>. It is essentially a collection of shortcuts for
loading different Emms features quickly, but everything you can do
with ‘emms-setup’ can also be done manually.
</p>
<p>We use ‘emms-setup’ by calling one of the setup functions.
</p>
<dl>
<dt><a name="index-emms_002dminimalistic"></a>Function: <strong>emms-minimalistic</strong></dt>
<dd><p>An Emms setup script.

<dl>
<dt><a name="index-emms_002dall"></a>Function: <strong>emms-all</strong></dt>
<dd><p>An Emms setup script.
Loads all the stable features which come with the Emms distribution.
</p></dd></dl>
<p>‘emms-setup’ also comes with a convenience function to set a default
list of media players.
</p>
<dl>
<dt><a name="index-emms_002ddefault_002dplayers"></a>Function: <strong>emms-default-players</strong></dt>
<dd><p>Set <var>emms-player-list</var> to <var>emms-setup-default-player-list</var>.

<p>You can of course write your own Emms setup functions like the above
by looking at the existing function definitions in

<h2 class="chapter">5 Configuration</h2>
<a name="index-Configuration"></a>
<p>This chapter discusses the configuration of Emms in more detail.
</p>
<p>The following code fragment provides a minimal Emms setup without
using the layer of ‘emms-setup’. It can maybe be used to better
understand the internals of Emms. You can see how Emms needs to know
about players (these are defined in ‘emms-player-simple’) and about
sources for tracks (trivial file system based sources, such as this
‘emms-directory-tree’, are defined in ‘emms-source-file’).
</p>
<div class="lisp">
<pre class="lisp">(require 'emms-player-simple)
(require 'emms-source-file)
(require 'emms-source-playlist)
(setq emms-player-list '(emms-player-mpg321
emms-player-ogg123
emms-player-mplayer))
</pre></div>
<p>For a discussion on how to define additional players, see See <a href="#Simple-Players">Simple Players</a>.
</p>
<p>Much of the behaviour of Emms can be changed by setting
variables. For example:
</p>
<div class="lisp">
<pre class="lisp">(setq emms-info-asynchronously nil)
(setq emms-playlist-buffer-name "*Music*")
</pre></div>
<p>The first <code>setq</code> turns off the asynchronous updating of info tags. The
second sets the default name of the Emms playlist buffer.
</p>
<p>Another way to change Emms variables is to use the M-x
<code>customize</code> mechanism provided by Emacs.

<h3 class="section">5.1 Finding files and speed</h3>
<a name="index-files"></a>
<a name="index-speed"></a>
<p>Emms needs to traverse directories in order to find playable
media. The default method Emms uses to achive this is
<code>emms-source-file-directory-tree-internal</code> as defined in
<samp>emms-source-file.el</samp>. The above method is written portably and
will always work, but might be too slow if we want to load several
hundred tracks (or more).
</p>
<p><samp>emms-source-file.el</samp> defines another method for finding files,
<code>emms-source-file-directory-tree-find</code> which uses
GNU/find. <code>emms-source-file-directory-tree-find</code> is usually an
order of magnitude faster, but of course will not work if you do not
have GNU/find installed.
</p>
<p>The method Emms will use is defined in the customisable variable
<var>emms-source-file-directory-tree-function</var>.

<h2 class="chapter">7 Formats and Freedom</h2>
<a name="index-freedom"></a>
<a name="index-format"></a>
<p>Emms is free software, but some of the file formats it can play carry
restrictions, they are proprietary file formats. Proprietary software
companies are pushing out audio and video formats which restrict when,
where and how you can play them, and restrict developers from writing
free software which interacts with them.
</p>
<p>Restrictive file formats put the corporate bottom-line before the
public interest.
</p>
<p>Fortunately there are alternatives like Ogg. Ogg is a professional
grade multimedia format. Ogg Vorbis is the compressed audio format
(like MP3), and Ogg Theora is the video format. For more information,
go to <a href="http://www.xiph.org/">http://www.xiph.org/</a>.
</p>
<p>If you want to transcode audio into a lossless format, you can try
FLAC (Free Lossless Audio Codec). FLAC stands out as the fastest and
most widely supported lossless audio codec, and the only one that at
once is non-proprietary, is unencumbered by patents and has the source
code for a reference implementation freely available. For more
information about FLAC, go to <a href="http://flac.sourceforge.net/">http://flac.sourceforge.net/</a>.

<p>Emms uses Emacs buffers to store the media tracks for playing. We call
one such buffer a “playlist buffer” or an “Emms playlist
buffer”. Emms then proceeds to play the media tracks in the buffer
from top to bottom until the end of the playlist.
</p>
<p>The name of the playlist buffer is defined in the variable
<var>emms-playlist-buffer-name</var> and is set to be an invisible Emacs
buffer by default. You can change to any name you want. For an example
configuration see See <a href="#Configuration">Configuration</a>.
</p>
<p>You can create any number of playlist buffers you wish. At any time
Emms has a single “current” buffer through which it proceeds track
by track.

<p>Emms is distributed with multiple predefined methods for retrieving
info, provided by <samp>emms-info-mp3info.el</samp>,
<samp>emms-info-ogginfo.el</samp>, <samp>emms-cue.el</samp> and
<samp>emms-info-libtag.el</samp>. The first two packages are front-ends for
command-line tools. Ogg track information is retrieved using the
<a href="http://directory.fsf.org/audio/ogg/vorbistools.html">ogginfo</a>
software. Likewise, mp3 track information is available using
<a href="http://www.ibiblio.org/mp3info/">mp3info</a>. <samp>emms-cue.el</samp>
retrieves tracks information for ape/flac files by parsing a cue sheet
file, which is plain text. Finally, <samp>emms-info-libtag.el</samp> uses a
tiny C shim (included in the src/ directory) program to take advantage
of <a href="http://taglib.github.io/">TagLib</a>.
</p>
<p>Automatic track information retrieval is enabled by default in the
‘emms-all’ setup level provided by <samp>emms-setup.el</samp>. For more
information about <samp>emms-setup.el</samp> see See <a href="#Setup">Setup</a>.
</p>
<p>If you would like to know how Emms track retreival works and how we
can define new methods for track retrieval see See <a href="#Defining-Info-Methods">Defining Info Methods</a>.
</p>
<p>There are a number of user variables which control the behaviour of
‘emms-info’.
</p>
<dl>
<dt><a name="index-emms_002dinfo_002dauto_002dupdate"></a>User Option: <strong>emms-info-auto-update</strong></dt>
<dd><p>Non-nil when Emms should update track information if the file changes.

written in C++ <samp>emms-print-metadata.cpp</samp>. To compile
<samp>emms-print-metadata</samp> invoke:

<p>It is of course also possible to install only the

execute it without installing all of Emms via the make command.
</p>

<p>The function <code>emms-info-ogginfo</code> provided by

argument and returns the appropriate information string.

program and can therefore be used to include titles and annotations
within the playlist.

<p>The Markable Playlists provided by the file <samp>emms-mark.el</samp> are an
alternative to the default interactive playlists, See <a href="#Interactive-Playlists">Interactive Playlists</a>. They allow marking tracks with keybindings familiar to users

</p>
<p>To enable the Markable Playlists you have to add
</p>
<div class="lisp">
<pre class="lisp">(require 'emms-mark)

<p>to your <samp>.emacs</samp>. Then you can activate <code>emms-mark-mode</code> by
executing <code>M-x emms-mark-mode</code> in a playlist buffer. You can
return to the default interactive playlist mode with <code>M-x
emms-mark-mode-disable</code>.

<a name="index-simple-player"></a>
<a name="index-primitive-player"></a>
<a name="index-basic-player"></a>
<p>Play is a very easy command line player for various format. If you
want your emms to play WAV files just put the following lines in you
<samp>.emacs</samp>:
</p>
<div class="lisp">
<pre class="lisp">(require 'emms-player-simple)
(define-emms-simple-player play '(file) "\\.wav$" "play")
</pre></div>
<p>Huh! Wasn’t that easy?
</p>
<p>The macro function <code>define-emms-simple-player</code> takes a minimum
of three arguments. The first argument (<em>play</em> in our example)
defines the name of the player. It’s used to name the player
functions. The second is a regexp, that defines which files to play
with our player. <em>\\.wav$</em> matches any filename ending with a dot
and the string wav. The last argument is the actual command line
command we use to play our files. You can also add the path but we
just assume that the command is in your path. All arguments you add to
these three are optional. They define the command line arguments you
want to add to your argument. If you want to hear the wav file of your
favourite artist in the most possible volume use the following line:
</p>
<div class="lisp">
<pre class="lisp">(require 'emms-player-simple)
(define-emms-simple-player play
'(file)
"\\artist-*.wav$"
"play"
"--volume=100")
</pre></div>
<p>Please notice that you have to add the arguments as strings!
</p>
<p>The command line tool you use for <code>define-emms-simple-player</code>
has to take one song as argument and stop after playing that
particular song. For any other concept you will need to customise
emms a bit more...

<h3 class="section">16.3 More Complex Player</h3>
<a name="index-complex-player"></a>
<a name="index-advanced-player"></a>
<p>The most players you use will be simple players so you don’t need to
read this chapter. But if you are curious how you can use (almost) every
player in emms read further...
</p>
<p>In this chapter we will use mpg321 to construct a player that
actually can pause a track, restart it and show rest time. We won’t
implement all of that, but after that chapter you will know how to
define it.
</p>
<p>The command <code>define-emms-simple-player</code> is just a abstraction
layer for <code>define-emms-player</code>, which is a little bit more
complicated but much more powerful!
</p>
<div class="lisp">
<pre class="lisp">(define-emms-player "emms-mpg321-remote"
:start 'emms-mpg321-remote-start
:stop 'emms-mpg321-remote-stop
:playablep 'emms-mpg321-remote-playable-p)
</pre></div>
<p>So, that is almost all! <code>define-emms-player</code> takes a minimum
of three arguments. The first is the name of the player. The rest are
methods with functions to call. Three methods are required: start,
stop and playable. Start says Emms how to start a track (sic!), stop
how to stop a player and playablep should return non-nil if the player
can play the track.
</p>
<p>So we just need these three functions to get our mpg321-remote:
</p>
<p>First we code the start function. We will check if there’s a open
process and start one otherwise. Then we send a string to the process
with the filename and set a filter.
</p>
<div class="lisp">
<pre class="lisp">(defun emms-mpg321-remote-start ()
(unless (get-process ``mpg321-remote'')
(setq emms-mpg321-remote-process
(start-process "mpg321-remote-process"
"*mpg321*" "mpg321" "-R" "abc"))
(process-send-string "mpg321-remote-process"
(concat "l " (emms-track-name track)))
(set-process-filter emms-mpg321-remote-process 'emms-mpg321-remote-filter)))
</pre></div>
<p>We need the filter, as mpg321-remote won’t quit after playing the
track as the simple player do. We wait until the process sends the
output “(at-sign)P 0” (the signal of mpg321 that the song ended) to the
filter and call emms-mpg321-remote-stop.
</p>
<div class="lisp">
<pre class="lisp">(defun emms-mpg321-remote-filter (process output)
(when (string-match "(at-sign)P 0" output)
(emms-mpg321-remote-stop)))
</pre></div>
<p><code>emms-mpg321-remote-stop</code> won’t do anything interesting. It
just test if there are other files to play and close the process otherwise.
</p>
<div class="lisp">
<pre class="lisp">(defun emms-mpg321-remote-stop ()
(unless emms-playlist
(process-send-string "mpg321-remote-process" "Q\n"))
</pre></div>
<p>And to make that a playable example I also added
<code>emms-mpg321-remote-playablep</code>, which I really just steal
from <samp>emms-player-simple.el</samp>
</p>
<div class="lisp">
<pre class="lisp">(defun emms-mpg321-remote-playablep (track)
"Return non-nil when we can play this track."
(and (eq 'file (emms-track-type track))
</pre></div>
<p>Now we have a ready player and we could add commands like
<code>emms-mpg321-remote-pause</code> for example.

<h3 class="section">17.2 Filtering Tracks</h3>
<p>If you want to display a subset of your collection (such as a
directory of 80s music, only avi files, etc.) then you can extend the
Browser by defining “filters”.
</p>
<p>Show everything:
</p>
<div class="lisp">
<pre class="lisp">(emms-browser-make-filter "all" 'ignore)
</pre></div>
<p>Set "all" as the default filter:
</p>
<div class="lisp">
<pre class="lisp">(emms-browser-set-filter (assoc "all" emms-browser-filters))
</pre></div>
<p>Show all files (no streamlists, etc):
</p>
<div class="lisp">
<pre class="lisp">(emms-browser-make-filter
"all-files" (emms-browser-filter-only-type 'file))
</pre></div>
<p>Show only tracks in one folder:
</p>
<div class="lisp">
<pre class="lisp">(emms-browser-make-filter
"80s" (emms-browser-filter-only-dir "~/Mp3s/80s"))
</pre></div>
<p>Show all tracks played in the last month:
</p>
<div class="lisp">
<pre class="lisp">(emms-browser-make-filter
"last-month" (emms-browser-filter-only-recent 30))
</pre></div>
<p>After executing the above commands, you can use M-x
emms-browser-show-all, emms-browser-show-80s, etc to toggle between
different collections. Alternatively you can use ’<’ and ’>’ to cycle
through the available filters.
</p>
<p>The second argument to make-filter is a function which returns t if a
single track should be filtered. You can write your own filter
functions to check the type of a file, etc.
</p>
<p>Show only tracks not played in the last year:
</p>
<div class="lisp">
<pre class="lisp">(emms-browser-make-filter "not-played"
(lambda (track)
(not (funcall (emms-browser-filter-only-recent 365) track))))
</pre></div>
<p>Show all files that are not in the pending directory:
</p>
<div class="lisp">
<pre class="lisp">(emms-browser-make-filter
"all"
(lambda (track)
(or
(funcall (emms-browser-filter-only-type 'file) track)
(not (funcall
(emms-browser-filter-only-dir "~/Media/pending") track)))))

<a name="Displaying-Covers-1"></a>
<h3 class="section">17.3 Displaying Covers</h3>
<p>The browser will attempt to display cover images if they’re
available. By default it looks for images <samp>cover_small.jpg</samp>,
<samp>cover_med.jpg</samp>, etc. Customize <var>emms-browser-covers</var> and
<var>emms-browser-covers-file-extensions</var> to use your own covers. Note
that you’ll probably want to resize your existing covers to particular
sizes. Suggested sizes are 100x100 for small, and 200x200 for medium.
</p>
<p>Also, Emacs by default will jump around a lot when scrolling a buffer
with images. In order to prevent that, you can set
<var>scroll-up-aggressively</var> and <var>scroll-down-aggressively</var> to the
number “0.0”.
</p>
<p>To show a ’no cover’ image for albums which don’t have a cover, add
the following code to your .emacs:
</p>
<div class="lisp">
<pre class="lisp">(setq emms-browser-default-covers
(list "/path/to/cover_small.jpg" nil nil)
</pre></div>
<p>The medium and large images can be set as well.
</p>
<p>You can download an example <a href="http://repose.cx/cover_small.jpg">‘no cover’ image</a>.

<p>The Browser’s look can be customised. You can change the way the tree
structure looks, the display format and display faces.
</p>
<a name="Changing-Tree-Structure"></a>
<h4 class="subheading">Changing Tree Structure</h4>
<p>You can change the way the tree is displayed by modifying the function
<code>emms-browser-next-mapping-type</code>.
</p>
<p>The following code displays artist->track instead of
artist->album->track when you switch to the ’singles’ filter:
</p>
<div class="lisp">
<pre class="lisp">(defadvice emms-browser-next-mapping-type

(ad-deactivate 'emms-browser-next-mapping-type)))
(add-hook 'emms-browser-filter-changed-hook 'toggle-album-display)
</pre></div>
<a name="Changing-Display-Format"></a>
<h4 class="subheading">Changing Display Format</h4>
<p>Format strings govern the way items are displayed in the browser and
playlist. You can customize these if you wish.
</p>
<p><var>emms-browser-default-format</var> controls the format to use when no
other format has been explicitly defined. By default, only track and
albums deviate from the default.
</p>
<p>To customise the format of a particular type, find the name of the
field you want to use (eg ‘info-artist’, ‘info-title’, etc), and
insert that into emms-browser-<type>-format or
emms-browser-playlist-<type>-format. For example, if you wanted to
remove track numbers from tracks in both the browser and playlist, you
could do:
</p>
<div class="lisp">
<pre class="lisp">(defvar emms-browser-info-title-format "%i%n")
(defvar emms-browser-playlist-info-title-format
emms-browser-info-title-format)
</pre></div>
<p>The format specifiers available include:
</p>
<ul class="no-bullet">
<li><!-- /@w --> %i indent relative to the current level
</li><li><!-- /@w --> %n the value of the item - eg -info-artist might be “pink floyd”
</li><li><!-- /@w --> %y the album year
</li><li><!-- /@w --> %A the album name
</li><li><!-- /@w --> %a the artist name of the track
</li><li><!-- /@w --> %t the title of the track
</li><li><!-- /@w --> %T the track number
</li><li><!-- /@w --> %cS a small album cover
</li><li><!-- /@w --> %cM a medium album cover
</li><li><!-- /@w --> %cL a big album cover
</li></ul>
<p>Note that if you use track-related items like %t, it will take the
data from the first track.
</p>
<a name="Changing-Display-Faces"></a>
<h4 class="subheading">Changing Display Faces</h4>
<p>The faces used to display the various fields are also customizable.
They are in the format emms-browser-<type>-face, where type is one of
"year/genre", "artist", "album" or "track". Note that faces lack the
initial "info-" part. For example, to change the artist face, type M-x
<code>customize-face</code> <code>emms-browser-artist-face</code>.

<a name="index-track-editor"></a>
<p>Using <samp>emms-tag-editor.el</samp>, emms can set tag informations of tracks
and write them back to the file with the help of external programs, such
as ‘mp3info’, ‘vorbiscomment’.
</p>
<p>Use the keybinding <kbd>E</kbd> to edit the tags of track under point in the
playlist or all marked tracks (see <a href="#Markable-Playlists">Markable Playlists</a> for how to
mark tracks). The track’s tag informations are listed in a special
buffer ‘*Emms-TAGS*’ in text format. Field names are marked in bold
face and are not editable. Any tag information is placed behind an
equal sign and is changable. A special field ‘name’ is the track’s file
name. If any change is made in this field, the track’s file will be
renamed to the new name. When you finished editing the tag infos use
<kbd>C-c C-c</kbd> (which calls <code>emms-tag-editor-submit-and-exit</code>) to
submit the changes and close the ‘*Emms-TAGS*’ buffer.
</p>
<p>There are a few commands to perform changes on all tracks.
</p>
<dl>
<dt><a name="index-emms_002dtag_002deditor_002dset_002dall"></a>Function: <strong>emms-tag-editor-set-all</strong> <em>tag value</em></dt>
<dd><p>Set TAG to VALUE in all tracks.
</p>
<p>If transient-mark-mode is turned on, you can apply the command to a
selected region.

<p>If ‘transient-mark-mode’ is on and the mark is active, the changes will
only take effect on the tracks in the region.

<p>For example, if the info-title tag is selected, then only perform
replacement in title tags.

<p>Emms provides an interface to the <a href="http://www.musicpd.org/">Music
Player Daemon</a>(MusicPD) software. The package is called ‘emms-player-mpd’ and
is provided by the file <samp>emms-player-mpd.el</samp>.
</p>
<p>The advantages of using MusicPD as an Emms backend include the
following.
</p>
<ul>
<li> minimal CPU usage
</li><li> fast access of track information
</li><li> optional crossfade
</li></ul>
<a name="Setup-2"></a>
<h4 class="subheading">Setup</h4>
<p>To load ‘emms-player-mpd’ invoke:
</p>
<div class="lisp">
<pre class="lisp">(require 'emms-player-mpd)
</pre></div>
<p>Set the variables <var>emms-player-mpd-server-name</var> and
<var>emms-player-mpd-server-port</var> to the location and port
(respectively) of your MusicPD server. For example:
</p>
<div class="lisp">
<pre class="lisp">(setq emms-player-mpd-server-name "localhost")
(setq emms-player-mpd-server-port "6600")
</pre></div>
<p>If your MusicPD setup requires a password, you will to set
<var>emms-player-mpd-server-password</var> as follows.
</p>
<div class="lisp">
<pre class="lisp">(setq emms-player-mpd-server-password "mypassword")
</pre></div>
<p>To get track information from MusicPD, invoke the following:
</p>
<div class="lisp">
<pre class="lisp">(add-to-list 'emms-info-functions 'emms-info-mpd)
</pre></div>
<p>Adding ‘emms-player-mpd’ to your Emms player list is accomplished by
invoking:
</p>
<div class="lisp">
<pre class="lisp">(add-to-list 'emms-player-list 'emms-player-mpd)
</pre></div>
<p>Unless your MusicPD is configured to use absolute file names, you must
set the emms-player-mpd-music-directory variable to the value of
’music_directory’ in your MusicPD configuration. There are
additional options available as well, but the defaults should be
sufficient for most uses.
</p>
<p>Once you’ve done the above, run the <kbd>M-x
emms-cache-set-from-mpd-all</kbd> command to fill the Emms cache with the
contents of your MusicPD database. The music in your MusicPD database
should then be accessible via the Emms browser.
</p>
<p>You can set <var>emms-player-mpd-sync-playlist</var> to nil if your master
Emms playlist contains only stored playlists.

<p>If you feel like binding those two functions to global keys — don’t do
it or you’ll miss the convenience of ‘emms-volume-minor-mode’. Instead,
bind the following two commands to some keys that you like.
</p>
<dl>
<dt><a name="index-emms_002dvolume_002dmode_002dplus"></a>Function: <strong>emms-volume-mode-plus</strong></dt>

<p>Example:
</p>
<div class="lisp">
<pre class="lisp">(global-set-key (kbd "C-c +") 'emms-volume-mode-plus)
(global-set-key (kbd "C-c -") 'emms-volume-mode-minus)
</pre></div>
<p>Whenever you use one of these keys or call these functions with
<kbd>M-x</kbd>, Emms will be put into ‘emms-volume-minor-mode’ for a short
period defined by ‘emms-volume-mode-timeout’.
</p>
<dl>
<dt><a name="index-emms_002dvolume_002dmode_002dtimeout"></a>User Option: <strong>emms-volume-mode-timeout</strong></dt>
<dd><p>The timeout in amount of seconds used by ‘emms-volume-minor-mode’.
</p></dd></dl>
<p>In this interval you can raise/lower the volume simply by pressing
<kbd>+</kbd> or <kbd>-</kbd>, which will also reset the timer to its initial
value. So instead of pressing <kbd>C-c +</kbd> six times to increase volume
by six steps of <code>emms-volume-change-amount</code>, you would simply type
<kbd>C-c + + + + + +</kbd>.
</p>
<p>Emms can change volume with amixer, mpd, PulseAudio out of the box, see
<var>emms-volume-change-function</var>.

<p>Emms provides a friendly interface for managing and playing streaming
audio in addition to the Emms playlist interface. The interface is
defined in the <samp>emms-streams.el</samp> package and can be loaded by
invoking:
</p>
<div class="lisp">
<pre class="lisp">(require 'emms-streams)
</pre></div>
<p>Querying the streams for track information is provided by the
<samp>emms-stream-info.el</samp> package and can be loaded with:
</p>
<div class="lisp">
<pre class="lisp">(require 'emms-stream-info)
</pre></div>
<p>The Emms interface for streaming audio, and the stream query
capabilites are enabled by default in the ‘emms-all’ setup level. For
more information about Emms setup levels see See <a href="#Setup">Setup</a>.
</p>
<p>‘emms-stream-info’ calls a backend program to query the stream for
information. The preferred program needs to be specified by setting
the variable <var>emms-stream-info-backend</var> either ‘mplayer’ or
‘vlc’. For instance:
</p>
<div class="lisp">
<pre class="lisp">(setq emms-stream-info-backend 'vlc)
</pre></div>
<p>Obviously, the corresponding program needs to be installed and
available for Emms to invoke.
</p>
<p>Enter the emms-streams interface by invoking <kbd>M-x</kbd>
<code>emms-streams</code>. The emms-streams interface comes with a
built-in, eclectic list of streaming audio channels from throughout the
Web. Emms can of-course play other streams than the ones listed by
default, you are free to remove any or all of them and add your
own.<a name="DOCF1" href="#FOOT1"><sup>1</sup></a>
</p>
<p>The following is a list of the key-bindings for the emms-streams
interface:

<p>Perform the default action when you press RET in the Emms Stream
interface. Can be either “add” or “play”. The default is “add”,
which adds the station under point to the Emms playlist. When

<p><a href="https://www.gnu.org/software/gnufm/">GNU FM</a> is free software for
running music community websites. It was created for the music
community site, <a href="http://libre.fm/">Libre.fm</a>.
</p>
<p>Emms can send track information, and stream music from GNU FM servers
using <samp>emms-librefm-scrobbler.el</samp> and
<samp>emms-librefm-stream.el</samp>, respectively.
</p>
<p>Emms is configured by default to use <a href="http://libre.fm/">Libre.fm</a>,
but can work with any GNU FM server by configuring the variable
<var>emms-librefm-scrobbler-handshake-url</var> to the URL of the GNU FM
server.
</p>
<p>The recommended way of providing your credentials to the GNU FM server
is by using an authinfo file. Add authentication to your auth-info
file, typically <samp>~/.authinfo.gpg</samp>, as:
</p><div class="smallexample">
<pre class="smallexample">machine libre.fm login USERNAME password PASSWORD
</pre></div>
<p>If you are using some other server than libre.fm, change
“‘<samp>libre.fm</samp>’” to match
<var>emms-librefm-scrobbler-handshake-url</var>.
</p>
<p>Alternatively, you can save the password in plaintext in your init-file
by setting these variables:
</p>
<div class="lisp">
<pre class="lisp">(setq emms-librefm-scrobbler-username "USERNAME"
emms-librefm-scrobbler-password "PASSWORD")

</div>
<div class="display">
<pre class="display">Copyright © 2007 Free Software Foundation, Inc. <a href="http://fsf.org/">http://fsf.org/</a>
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
</pre></div>
<a name="Preamble"></a>
<h3 class="unnumberedsec">Preamble</h3>
<p>The GNU General Public License is a free, copyleft license for
software and other kinds of works.
</p>
<p>The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom
to share and change all versions of a program–to make sure it remains
free software for all its users. We, the Free Software Foundation,
use the GNU General Public License for most of our software; it
applies also to any other work released this way by its authors. You
can apply it to your programs, too.
</p>
<p>When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
</p>
<p>To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you
have certain responsibilities if you distribute copies of the
software, or if you modify it: responsibilities to respect the freedom
of others.
</p>
<p>For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too,
receive or can get the source code. And you must show them these
terms so they know their rights.
</p>
<p>Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
</p>
<p>For the developers’ and authors’ protection, the GPL clearly explains
that there is no warranty for this free software. For both users’ and
authors’ sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
</p>
<p>Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the
manufacturer can do so. This is fundamentally incompatible with the
aim of protecting users’ freedom to change the software. The
systematic pattern of such abuse occurs in the area of products for
individuals to use, which is precisely where it is most unacceptable.
Therefore, we have designed this version of the GPL to prohibit the
practice for those products. If such problems arise substantially in
other domains, we stand ready to extend this provision to those
domains in future versions of the GPL, as needed to protect the
freedom of users.
</p>
<p>Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish
to avoid the special danger that patents applied to a free program
could make it effectively proprietary. To prevent this, the GPL
assures that patents cannot be used to render the program non-free.
</p>
<p>The precise terms and conditions for copying, distribution and
modification follow.
</p>
<ol start="0">
<li> Definitions.
<p>“This License” refers to version 3 of the GNU General Public License.
</p>
<p>“Copyright” also means copyright-like laws that apply to other kinds
of works, such as semiconductor masks.
</p>
<p>“The Program” refers to any copyrightable work licensed under this
License. Each licensee is addressed as “you”. “Licensees” and
“recipients” may be individuals or organizations.
</p>
<p>To “modify” a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of
an exact copy. The resulting work is called a “modified version” of
the earlier work or a work “based on” the earlier work.
</p>
<p>A “covered work” means either the unmodified Program or a work based
on the Program.
</p>
<p>To “propagate” a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
</p>
<p>To “convey” a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user
through a computer network, with no transfer of a copy, is not
conveying.
</p>
<p>An interactive user interface displays “Appropriate Legal Notices” to
the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
</p>
</li><li> Source Code.
<p>The “source code” for a work means the preferred form of the work for
making modifications to it. “Object code” means any non-source form
of a work.
</p>
<p>A “Standard Interface” means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
</p>
<p>The “System Libraries” of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
“Major Component”, in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
</p>
<p>The “Corresponding Source” for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work’s
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
</p>
<p>The Corresponding Source need not include anything that users can
regenerate automatically from other parts of the Corresponding Source.
</p>
<p>The Corresponding Source for a work in source code form is that same
work.
</p>
</li><li> Basic Permissions.
<p>All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
</p>
<p>You may make, run and propagate covered works that you do not convey,
without conditions so long as your license otherwise remains in force.
You may convey covered works to others for the sole purpose of having
them make modifications exclusively for you, or provide you with
facilities for running those works, provided that you comply with the
terms of this License in conveying all material for which you do not
control copyright. Those thus making or running the covered works for
you must do so exclusively on your behalf, under your direction and
control, on terms that prohibit them from making any copies of your
copyrighted material outside their relationship with you.
</p>
<p>Conveying under any other circumstances is permitted solely under the
conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
</p>
</li><li> Protecting Users’ Legal Rights From Anti-Circumvention Law.
<p>No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
</p>
<p>When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such
circumvention is effected by exercising rights under this License with
respect to the covered work, and you disclaim any intention to limit
operation or modification of the work as a means of enforcing, against
the work’s users, your or third parties’ legal rights to forbid
circumvention of technological measures.
</p>
</li><li> Conveying Verbatim Copies.
<p>You may convey verbatim copies of the Program’s source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
</p>
<p>You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
</p>
</li><li> Conveying Modified Source Versions.
<p>You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these
conditions:
</p>
<ol type="a" start="1">
<li> The work must carry prominent notices stating that you modified it,
and giving a relevant date.
</li><li> The work must carry prominent notices stating that it is released
under this License and any conditions added under section 7. This
requirement modifies the requirement in section 4 to “keep intact all
notices”.
</li><li> You must license the entire work, as a whole, under this License to
anyone who comes into possession of a copy. This License will
therefore apply, along with any applicable section 7 additional terms,
to the whole of the work, and all its parts, regardless of how they
are packaged. This License gives no permission to license the work in
any other way, but it does not invalidate such permission if you have
separately received it.
</li><li> If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your work
need not make them do so.
</li></ol>
<p>A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
“aggregate” if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation’s users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
</p>
</li><li> Conveying Non-Source Forms.
<p>You may convey a covered work in object code form under the terms of
sections 4 and 5, provided that you also convey the machine-readable
Corresponding Source under the terms of this License, in one of these
ways:
</p>
<ol type="a" start="1">
<li> Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium customarily
used for software interchange.
</li><li> Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a written
offer, valid for at least three years and valid for as long as you
offer spare parts or customer support for that product model, to give
anyone who possesses the object code either (1) a copy of the
Corresponding Source for all the software in the product that is
covered by this License, on a durable physical medium customarily used
for software interchange, for a price no more than your reasonable
cost of physically performing this conveying of source, or (2) access
to copy the Corresponding Source from a network server at no charge.
</li><li> Convey individual copies of the object code with a copy of the written
offer to provide the Corresponding Source. This alternative is
allowed only occasionally and noncommercially, and only if you
received the object code with such an offer, in accord with subsection
6b.
</li><li> Convey the object code by offering access from a designated place
(gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to copy
the object code is a network server, the Corresponding Source may be
on a different server (operated by you or a third party) that supports
equivalent copying facilities, provided you maintain clear directions
next to the object code saying where to find the Corresponding Source.
Regardless of what server hosts the Corresponding Source, you remain
obligated to ensure that it is available for as long as needed to
satisfy these requirements.
</li><li> Convey the object code using peer-to-peer transmission, provided you
inform other peers where the object code and Corresponding Source of
the work are being offered to the general public at no charge under
subsection 6d.
</li></ol>
<p>A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
</p>
<p>A “User Product” is either (1) a “consumer product”, which means any
tangible personal property which is normally used for personal,
family, or household purposes, or (2) anything designed or sold for
incorporation into a dwelling. In determining whether a product is a
consumer product, doubtful cases shall be resolved in favor of
coverage. For a particular product received by a particular user,
“normally used” refers to a typical or common use of that class of
product, regardless of the status of the particular user or of the way
in which the particular user actually uses, or expects or is expected
to use, the product. A product is a consumer product regardless of
whether the product has substantial commercial, industrial or
non-consumer uses, unless such uses represent the only significant
mode of use of the product.
</p>
<p>“Installation Information” for a User Product means any methods,
procedures, authorization keys, or other information required to
install and execute modified versions of a covered work in that User
Product from a modified version of its Corresponding Source. The
information must suffice to ensure that the continued functioning of
the modified object code is in no case prevented or interfered with
solely because modification has been made.
</p>
<p>If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
</p>
<p>The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or
updates for a work that has been modified or installed by the
recipient, or for the User Product in which it has been modified or
installed. Access to a network may be denied when the modification
itself materially and adversely affects the operation of the network
or violates the rules and protocols for communication across the
network.
</p>
<p>Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
</p>
</li><li> Additional Terms.
<p>“Additional permissions” are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
</p>
<p>When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
</p>
<p>Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders
of that material) supplement the terms of this License with terms:
</p>
<ol type="a" start="1">
<li> Disclaiming warranty or limiting liability differently from the terms
of sections 15 and 16 of this License; or
</li><li> Requiring preservation of specified reasonable legal notices or author
attributions in that material or in the Appropriate Legal Notices
displayed by works containing it; or
</li><li> Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
</li><li> Limiting the use for publicity purposes of names of licensors or
authors of the material; or
</li><li> Declining to grant rights under trademark law for use of some trade
names, trademarks, or service marks; or
</li><li> Requiring indemnification of licensors and authors of that material by
anyone who conveys the material (or modified versions of it) with
contractual assumptions of liability to the recipient, for any
liability that these contractual assumptions directly impose on those
licensors and authors.
</li></ol>
<p>All other non-permissive additional terms are considered “further
restrictions” within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
</p>
<p>If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
</p>
<p>Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions; the
above requirements apply either way.
</p>
</li><li> Termination.
<p>You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
</p>
<p>However, if you cease all violation of this License, then your license
from a particular copyright holder is reinstated (a) provisionally,
unless and until the copyright holder explicitly and finally
terminates your license, and (b) permanently, if the copyright holder
fails to notify you of the violation by some reasonable means prior to
60 days after the cessation.
</p>
<p>Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
</p>
<p>Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
</p>
</li><li> Acceptance Not Required for Having Copies.
<p>You are not required to accept this License in order to receive or run
a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
</p>
</li><li> Automatic Licensing of Downstream Recipients.
<p>Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
</p>
<p>An “entity transaction” is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party’s predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
</p>
<p>You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
</p>
</li><li> Patents.
<p>A “contributor” is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor’s “contributor version”.
</p>
<p>A contributor’s “essential patent claims” are all patent claims owned
or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, “control” includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
</p>
<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor’s essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
</p>
<p>In the following three paragraphs, a “patent license” is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To “grant” such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
</p>
<p>If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. “Knowingly relying” means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient’s use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
</p>
<p>If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
</p>
<p>A patent license is “discriminatory” if it does not include within the
scope of its coverage, prohibits the exercise of, or is conditioned on
the non-exercise of one or more of the rights that are specifically
granted under this License. You may not convey a covered work if you
are a party to an arrangement with a third party that is in the
business of distributing software, under which you make payment to the
third party based on the extent of your activity of conveying the
work, and under which the third party grants, to any of the parties
who would receive the covered work from you, a discriminatory patent
license (a) in connection with copies of the covered work conveyed by
you (or copies made from those copies), or (b) primarily for and in
connection with specific products or compilations that contain the
covered work, unless you entered into that arrangement, or that patent
license was granted, prior to 28 March 2007.
</p>
<p>Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
</p>
</li><li> No Surrender of Others’ Freedom.
<p>If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey
a covered work so as to satisfy simultaneously your obligations under
this License and any other pertinent obligations, then as a
consequence you may not convey it at all. For example, if you agree
to terms that obligate you to collect a royalty for further conveying
from those to whom you convey the Program, the only way you could
satisfy both those terms and this License would be to refrain entirely
from conveying the Program.
</p>
</li><li> Use with the GNU Affero General Public License.
<p>Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
</p>
</li><li> Revised Versions of this License.
<p>The Free Software Foundation may publish revised and/or new versions
of the GNU General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
</p>
<p>Each version is given a distinguishing version number. If the Program
specifies that a certain numbered version of the GNU General Public
License “or any later version” applies to it, you have the option of
following the terms and conditions either of that numbered version or
of any later version published by the Free Software Foundation. If
the Program does not specify a version number of the GNU General
Public License, you may choose any version ever published by the Free
Software Foundation.
</p>
<p>If the Program specifies that a proxy can decide which future versions
of the GNU General Public License can be used, that proxy’s public
statement of acceptance of a version permanently authorizes you to
choose that version for the Program.
</p>
<p>Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
</p>
</li><li> Disclaimer of Warranty.
<p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
</p>
</li><li> Limitation of Liability.
<p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
</p>
</li><li> Interpretation of Sections 15 and 16.
<p>If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.

<a name="How-to-Apply-These-Terms-to-Your-New-Programs"></a>
<h3 class="unnumberedsec">How to Apply These Terms to Your New Programs</h3>
<p>If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
</p>
<p>To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the “copyright” line and a pointer to where the full notice is found.
</p><div class="smallexample">
<pre class="smallexample"><var>one line to give the program's name and a brief idea of what it does.</var>
Copyright (C) <var>year</var> <var>name of author</var>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or (at
your option) any later version.
This program is distributed in the hope that it will be useful, but
WITHOUT ANY WARRANTY; without even the implied warranty of

General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <a href="http://www.gnu.org/licenses/">http://www.gnu.org/licenses/</a>.
</pre></div>
<p>Also add information on how to contact you by electronic and paper mail.
</p>
<p>If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
</p>
<div class="smallexample">
<pre class="smallexample"><var>program</var> Copyright (C) <var>year</var> <var>name of author</var>
This program comes with ABSOLUTELY NO WARRANTY; for details type ‘<samp>show w</samp>’.
This is free software, and you are welcome to redistribute it under certain conditions; type ‘<samp>show c</samp>’ for details.
</pre></div>
<p>The hypothetical commands ‘<samp>show w</samp>’ and ‘<samp>show c</samp>’ should show
the appropriate parts of the General Public License. Of course, your
program’s commands might be different; for a GUI interface, you would
use an “about box”.
</p>
<p>You should also get your employer (if you work as a programmer) or school,
if any, to sign a “copyright disclaimer” for the program, if necessary.

<a href="http://www.gnu.org/licenses/">http://www.gnu.org/licenses/</a>.
</p>
<p>The GNU General Public License does not permit incorporating your
program into proprietary programs. If your program is a subroutine
library, you may consider it more useful to permit linking proprietary
applications with the library. If this is what you want to do, use
the GNU Lesser General Public License instead of this License. But

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
</pre></div>
<ol start="0">
<li> PREAMBLE
<p>The purpose of this License is to make a manual, textbook, or other
functional and useful document <em>free</em> in the sense of freedom: to
assure everyone the effective freedom to copy and redistribute it,
with or without modifying it, either commercially or noncommercially.
Secondarily, this License preserves for the author and publisher a way
to get credit for their work, while not being considered responsible
for modifications made by others.
</p>
<p>This License is a kind of “copyleft”, which means that derivative
works of the document must themselves be free in the same sense. It
complements the GNU General Public License, which is a copyleft
license designed for free software.
</p>
<p>We have designed this License in order to use it for manuals for free
software, because free software needs free documentation: a free
program should come with manuals providing the same freedoms that the
software does. But this License is not limited to software manuals;
it can be used for any textual work, regardless of subject matter or
whether it is published as a printed book. We recommend this License
principally for works whose purpose is instruction or reference.
</p>
</li><li> APPLICABILITY AND DEFINITIONS
<p>This License applies to any manual or other work, in any medium, that
contains a notice placed by the copyright holder saying it can be
distributed under the terms of this License. Such a notice grants a
world-wide, royalty-free license, unlimited in duration, to use that
work under the conditions stated herein. The “Document”, below,
refers to any such manual or work. Any member of the public is a
licensee, and is addressed as “you”. You accept the license if you
copy, modify or distribute the work in a way requiring permission
under copyright law.
</p>
<p>A “Modified Version” of the Document means any work containing the
Document or a portion of it, either copied verbatim, or with
modifications and/or translated into another language.
</p>
<p>A “Secondary Section” is a named appendix or a front-matter section
of the Document that deals exclusively with the relationship of the
publishers or authors of the Document to the Document’s overall
subject (or to related matters) and contains nothing that could fall
directly within that overall subject. (Thus, if the Document is in
part a textbook of mathematics, a Secondary Section may not explain
any mathematics.) The relationship could be a matter of historical
connection with the subject or with related matters, or of legal,
commercial, philosophical, ethical or political position regarding
them.
</p>
<p>The “Invariant Sections” are certain Secondary Sections whose titles
are designated, as being those of Invariant Sections, in the notice
that says that the Document is released under this License. If a
section does not fit the above definition of Secondary then it is not
allowed to be designated as Invariant. The Document may contain zero
Invariant Sections. If the Document does not identify any Invariant
Sections then there are none.
</p>
<p>The “Cover Texts” are certain short passages of text that are listed,
as Front-Cover Texts or Back-Cover Texts, in the notice that says that
the Document is released under this License. A Front-Cover Text may
be at most 5 words, and a Back-Cover Text may be at most 25 words.
</p>
<p>A “Transparent” copy of the Document means a machine-readable copy,
represented in a format whose specification is available to the
general public, that is suitable for revising the document
straightforwardly with generic text editors or (for images composed of
pixels) generic paint programs or (for drawings) some widely available
drawing editor, and that is suitable for input to text formatters or
for automatic translation to a variety of formats suitable for input
to text formatters. A copy made in an otherwise Transparent file
format whose markup, or absence of markup, has been arranged to thwart
or discourage subsequent modification by readers is not Transparent.
An image format is not Transparent if used for any substantial amount
of text. A copy that is not “Transparent” is called “Opaque”.
</p>
<p>Examples of suitable formats for Transparent copies include plain
<small>ASCII</small> without markup, Texinfo input format, LaTeX input
format, <acronym>SGML</acronym> or <acronym>XML</acronym> using a publicly available
<acronym>DTD</acronym>, and standard-conforming simple <acronym>HTML</acronym>,
PostScript or <acronym>PDF</acronym> designed for human modification. Examples
of transparent image formats include <acronym>PNG</acronym>, <acronym>XCF</acronym> and
<acronym>JPG</acronym>. Opaque formats include proprietary formats that can be
read and edited only by proprietary word processors, <acronym>SGML</acronym> or
<acronym>XML</acronym> for which the <acronym>DTD</acronym> and/or processing tools are
not generally available, and the machine-generated <acronym>HTML</acronym>,
PostScript or <acronym>PDF</acronym> produced by some word processors for
output purposes only.
</p>
<p>The “Title Page” means, for a printed book, the title page itself,
plus such following pages as are needed to hold, legibly, the material
this License requires to appear in the title page. For works in
formats which do not have any title page as such, “Title Page” means
the text near the most prominent appearance of the work’s title,
preceding the beginning of the body of the text.
</p>
<p>A section “Entitled XYZ” means a named subunit of the Document whose
title either is precisely XYZ or contains XYZ in parentheses following
text that translates XYZ in another language. (Here XYZ stands for a
specific section name mentioned below, such as “Acknowledgements”,
“Dedications”, “Endorsements”, or “History”.) To “Preserve the Title”
of such a section when you modify the Document means that it remains a
section “Entitled XYZ” according to this definition.
</p>
<p>The Document may include Warranty Disclaimers next to the notice which
states that this License applies to the Document. These Warranty
Disclaimers are considered to be included by reference in this
License, but only as regards disclaiming warranties: any other
implication that these Warranty Disclaimers may have is void and has
no effect on the meaning of this License.
</p>
</li><li> VERBATIM COPYING
<p>You may copy and distribute the Document in any medium, either
commercially or noncommercially, provided that this License, the
copyright notices, and the license notice saying this License applies
to the Document are reproduced in all copies, and that you add no other
conditions whatsoever to those of this License. You may not use
technical measures to obstruct or control the reading or further
copying of the copies you make or distribute. However, you may accept
compensation in exchange for copies. If you distribute a large enough
number of copies you must also follow the conditions in section 3.
</p>
<p>You may also lend copies, under the same conditions stated above, and
you may publicly display copies.
</p>
</li><li> COPYING IN QUANTITY
<p>If you publish printed copies (or copies in media that commonly have
printed covers) of the Document, numbering more than 100, and the
Document’s license notice requires Cover Texts, you must enclose the
copies in covers that carry, clearly and legibly, all these Cover
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
the back cover. Both covers must also clearly and legibly identify
you as the publisher of these copies. The front cover must present
the full title with all words of the title equally prominent and
visible. You may add other material on the covers in addition.
Copying with changes limited to the covers, as long as they preserve
the title of the Document and satisfy these conditions, can be treated
as verbatim copying in other respects.
</p>
<p>If the required texts for either cover are too voluminous to fit
legibly, you should put the first ones listed (as many as fit
reasonably) on the actual cover, and continue the rest onto adjacent
pages.
</p>
<p>If you publish or distribute Opaque copies of the Document numbering
more than 100, you must either include a machine-readable Transparent
copy along with each Opaque copy, or state in or with each Opaque copy
a computer-network location from which the general network-using
public has access to download using public-standard network protocols
a complete Transparent copy of the Document, free of added material.
If you use the latter option, you must take reasonably prudent steps,
when you begin distribution of Opaque copies in quantity, to ensure
that this Transparent copy will remain thus accessible at the stated
location until at least one year after the last time you distribute an
Opaque copy (directly or through your agents or retailers) of that
edition to the public.
</p>
<p>It is requested, but not required, that you contact the authors of the
Document well before redistributing any large number of copies, to give
them a chance to provide you with an updated version of the Document.
</p>
</li><li> MODIFICATIONS
<p>You may copy and distribute a Modified Version of the Document under
the conditions of sections 2 and 3 above, provided that you release
the Modified Version under precisely this License, with the Modified
Version filling the role of the Document, thus licensing distribution
and modification of the Modified Version to whoever possesses a copy
of it. In addition, you must do these things in the Modified Version:
</p>
<ol type="A" start="1">
<li> Use in the Title Page (and on the covers, if any) a title distinct
from that of the Document, and from those of previous versions
(which should, if there were any, be listed in the History section
of the Document). You may use the same title as a previous version
if the original publisher of that version gives permission.
</li><li> List on the Title Page, as authors, one or more persons or entities
responsible for authorship of the modifications in the Modified
Version, together with at least five of the principal authors of the
Document (all of its principal authors, if it has fewer than five),
unless they release you from this requirement.
</li><li> State on the Title page the name of the publisher of the
Modified Version, as the publisher.
</li><li> Preserve all the copyright notices of the Document.
</li><li> Add an appropriate copyright notice for your modifications
adjacent to the other copyright notices.
</li><li> Include, immediately after the copyright notices, a license notice
giving the public permission to use the Modified Version under the
terms of this License, in the form shown in the Addendum below.
</li><li> Preserve in that license notice the full lists of Invariant Sections
and required Cover Texts given in the Document’s license notice.
</li><li> Include an unaltered copy of this License.
</li><li> Preserve the section Entitled “History”, Preserve its Title, and add
to it an item stating at least the title, year, new authors, and
publisher of the Modified Version as given on the Title Page. If
there is no section Entitled “History” in the Document, create one
stating the title, year, authors, and publisher of the Document as
given on its Title Page, then add an item describing the Modified
Version as stated in the previous sentence.
</li><li> Preserve the network location, if any, given in the Document for
public access to a Transparent copy of the Document, and likewise
the network locations given in the Document for previous versions
it was based on. These may be placed in the “History” section.
You may omit a network location for a work that was published at
least four years before the Document itself, or if the original
publisher of the version it refers to gives permission.
</li><li> For any section Entitled “Acknowledgements” or “Dedications”, Preserve
the Title of the section, and preserve in the section all the
substance and tone of each of the contributor acknowledgements and/or
dedications given therein.
</li><li> Preserve all the Invariant Sections of the Document,
unaltered in their text and in their titles. Section numbers
or the equivalent are not considered part of the section titles.
</li><li> Delete any section Entitled “Endorsements”. Such a section
may not be included in the Modified Version.
</li><li> Do not retitle any existing section to be Entitled “Endorsements” or
to conflict in title with any Invariant Section.
</li><li> Preserve any Warranty Disclaimers.
</li></ol>
<p>If the Modified Version includes new front-matter sections or
appendices that qualify as Secondary Sections and contain no material
copied from the Document, you may at your option designate some or all
of these sections as invariant. To do this, add their titles to the
list of Invariant Sections in the Modified Version’s license notice.
These titles must be distinct from any other section titles.
</p>
<p>You may add a section Entitled “Endorsements”, provided it contains
nothing but endorsements of your Modified Version by various
parties—for example, statements of peer review or that the text has
been approved by an organization as the authoritative definition of a
standard.
</p>
<p>You may add a passage of up to five words as a Front-Cover Text, and a
passage of up to 25 words as a Back-Cover Text, to the end of the list
of Cover Texts in the Modified Version. Only one passage of
Front-Cover Text and one of Back-Cover Text may be added by (or
through arrangements made by) any one entity. If the Document already
includes a cover text for the same cover, previously added by you or
by arrangement made by the same entity you are acting on behalf of,
you may not add another; but you may replace the old one, on explicit
permission from the previous publisher that added the old one.
</p>
<p>The author(s) and publisher(s) of the Document do not by this License
give permission to use their names for publicity for or to assert or
imply endorsement of any Modified Version.
</p>
</li><li> COMBINING DOCUMENTS
<p>You may combine the Document with other documents released under this
License, under the terms defined in section 4 above for modified
versions, provided that you include in the combination all of the
Invariant Sections of all of the original documents, unmodified, and
list them all as Invariant Sections of your combined work in its
license notice, and that you preserve all their Warranty Disclaimers.
</p>
<p>The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single
copy. If there are multiple Invariant Sections with the same name but
different contents, make the title of each such section unique by
adding at the end of it, in parentheses, the name of the original
author or publisher of that section if known, or else a unique number.
Make the same adjustment to the section titles in the list of
Invariant Sections in the license notice of the combined work.
</p>
<p>In the combination, you must combine any sections Entitled “History”
in the various original documents, forming one section Entitled
“History”; likewise combine any sections Entitled “Acknowledgements”,
and any sections Entitled “Dedications”. You must delete all
sections Entitled “Endorsements.”
</p>
</li><li> COLLECTIONS OF DOCUMENTS
<p>You may make a collection consisting of the Document and other documents
released under this License, and replace the individual copies of this
License in the various documents with a single copy that is included in
the collection, provided that you follow the rules of this License for
verbatim copying of each of the documents in all other respects.
</p>
<p>You may extract a single document from such a collection, and distribute
it individually under this License, provided you insert a copy of this
License into the extracted document, and follow this License in all
other respects regarding verbatim copying of that document.
</p>
</li><li> AGGREGATION WITH INDEPENDENT WORKS
<p>A compilation of the Document or its derivatives with other separate
and independent documents or works, in or on a volume of a storage or
distribution medium, is called an “aggregate” if the copyright
resulting from the compilation is not used to limit the legal rights
of the compilation’s users beyond what the individual works permit.
When the Document is included in an aggregate, this License does not
apply to the other works in the aggregate which are not themselves
derivative works of the Document.
</p>
<p>If the Cover Text requirement of section 3 is applicable to these
copies of the Document, then if the Document is less than one half of
the entire aggregate, the Document’s Cover Texts may be placed on
covers that bracket the Document within the aggregate, or the
electronic equivalent of covers if the Document is in electronic form.
Otherwise they must appear on printed covers that bracket the whole
aggregate.
</p>
</li><li> TRANSLATION
<p>Translation is considered a kind of modification, so you may
distribute translations of the Document under the terms of section 4.
Replacing Invariant Sections with translations requires special
permission from their copyright holders, but you may include
translations of some or all Invariant Sections in addition to the
original versions of these Invariant Sections. You may include a
translation of this License, and all the license notices in the
Document, and any Warranty Disclaimers, provided that you also include
the original English version of this License and the original versions
of those notices and disclaimers. In case of a disagreement between
the translation and the original version of this License or a notice
or disclaimer, the original version will prevail.
</p>
<p>If a section in the Document is Entitled “Acknowledgements”,
“Dedications”, or “History”, the requirement (section 4) to Preserve
its Title (section 1) will typically require changing the actual
title.
</p>
</li><li> TERMINATION
<p>You may not copy, modify, sublicense, or distribute the Document except
as expressly provided for under this License. Any other attempt to
copy, modify, sublicense or distribute the Document is void, and will
automatically terminate your rights under this License. However,
parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as such
parties remain in full compliance.
</p>
</li><li> FUTURE REVISIONS OF THIS LICENSE
<p>The Free Software Foundation may publish new, revised versions
of the GNU Free Documentation License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns. See
<a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>.
</p>
<p>Each version of the License is given a distinguishing version number.
If the Document specifies that a particular numbered version of this
License “or any later version” applies to it, you have the option of
