Emms organizes playlists, allows -browsing through track and album metadata, and plays files by calling -external players. - - This manual tries to be the definitive source of information about -Emms, an online version of the manual is available at: -<http://www.gnu.org/software/emms/manual/>. - - The basic functionality of Emms consists of three parts: The core, -the sources, and the players. - - The core resides in 'emms.el', 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. - - To get to tracks, the core needs sources. The file -'emms-source-file.el' provides simple sources to interact with the file -system. - - When Emms finally has the sources in the playlist, it needs a player -to play them. 'emms-player-simple.el' defines a few useful players and -provides a straightforward way of providing your own. - - The Emms comes with many additional features to extend the -functionality beyond the core. - - The way Emms works is easy to customize with your own code or by -using 'M-x customize' or by changing the variables directly. - - -File: emms.info, Node: Quickstart Guide, Next: Installation, Prev: Introduction, Up: Top - -2 Quickstart Guide -****************** - -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. - - The first thing you do is to load Emms via GNU ELPA. But if you are -installing manually, then start by telling Emacs where Emms is located. -Let's say you have it in '~/elisp/emms/'. So add this line to your -'.emacs': - - (add-to-list 'load-path "~/elisp/emms/lisp/") - - More detailed information about installing Emms can be found in the -installation chapter, *Note Installation::. - - You'll then want to load Emms into Emacs. To achieve this you invoke -the 'emms-all' setup function by adding the following three lines to -your Emacs initialization file. - - (require 'emms-setup) - (emms-all) - (emms-default-players) - - The function 'emms-default-players' 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, -mpv, vlc, etc.. To be sure that emms can play all your music you should -check that your preferred players are installed on the machine. - - More detail about setting up Emms can be found in the setup chapter, -*Note Setup::. - - 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 a number -of pieces of software and libraries as sources for track info, see *Note -Track Information:: for more. - - The last thing to do is to tell Emms where is your music; the root -directory of our music collection. Let's say all your music is in -'~/Music' or in subdirectories thereof: - - (setq emms-source-file-default-directory "~/Music/") - - OK, now we've set up Emms. Reload your Emacs initialization file or -restart Emacs to let the changes have an effect. - - Now we will add all our music to a playlist by invoking 'M-x -emms-add-directory-tree RET ~/Music/ RET'. We do this because then Emms -will read the tags of all your music files and caches them (the cache is -also required for the Emms browser, *Note The Browser::.) - - To switch to the playlist buffer, invoke 'M-x emms-playlist-mode-go' -or simply 'M-x emms'. You may see that some tracks are displayed with -their file name, but as Emms asynchronously populates its tag cache, -track by track, the filenames get replaced with the artist and track -name of the file's tag. - - Go ahead and navigate to a track and hit 'RET' on it to start -playback. - - Now you can start exploring Emms. It's probably best to begin with -the basic commands (*note Basic Commands::), the interactive playlists -(*note Interactive Playlists::), and the browser (*note The Browser::). - - -File: emms.info, Node: Installation, Next: Setup, Prev: Quickstart Guide, Up: Top - -3 Installation -************** - -Emms is available via GNU ELPA, which takes care of all of the following -steps automatically. - - If you are installing Emms manually, you need to put all the .el -files of emms in a directory in your load-path. For example, if you put -all those files into ~/elisp/emms/, then in your ~/.emacs, you should -add: - - (add-to-list 'load-path "~/elisp/emms/lisp/") - -* Menu: - -* Compiling Emms:: Compiling Emms into Byte-Code. - - -File: emms.info, Node: Compiling Emms, Up: Installation - -3.1 Compiling Emms -================== - -If you are using XEmacs, you will need to edit 'Makefile' as follows -before continuing. - - EMACS=xemacs - SITEFLAG=-no-site-file - - You can byte-compile Emms by first entering the directory containing -the Emms source code, followed by invoking: - - 'make' - - Which will byte compile Emms. You can then invoke: - - 'make install' - - Which will install Emms into your Emacs directories (provided you -have the appropriate permissions to do so on your system). - - Note that Emms is a light-weight and agile program, you can therefore -run Emms just fine without byte compiling it. - - -File: emms.info, Node: Setup, Next: Configuration, Prev: Installation, Up: Top - -4 Setup -******* - -The 'emms-setup' feature is provided by the file 'emms-setup.el'. 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. - - We use 'emms-setup' by calling one of the setup functions. - - -- Function: emms-minimalistic - An Emms setup script. Playlists and all the basics for playing - media, but nothing else. - - -- Function: emms-all - An Emms setup script. Loads all the stable features which come - with the Emms distribution. - - 'emms-setup' also comes with a convenience function to set a default -list of media players. - - -- Function: emms-default-players - Set EMMS-PLAYER-LIST to EMMS-SETUP-DEFAULT-PLAYER-LIST. - - You can of course write your own Emms setup functions like the above -by looking at the existing function definitions in 'emms-setup.el'. - - -File: emms.info, Node: Configuration, Next: Getting Help, Prev: Setup, Up: Top - -5 Configuration -*************** - -This chapter discusses the configuration of Emms in more detail. - - 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'). - - (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)) - - For a discussion on how to define additional players, see *Note -Simple Players::. - - Much of the behaviour of Emms can be changed by setting variables. -For example: - - (setq emms-info-asynchronously nil) - (setq emms-playlist-buffer-name "*Music*") - - The first 'setq' turns off the asynchronous updating of info tags. -The second sets the default name of the Emms playlist buffer. - - Another way to change Emms variables is to use the M-x 'customize' -mechanism provided by Emacs. - -* Menu: - -* Finding files and speed:: Finding files quickly or portably. -* Setup Examples:: Examples of ways to setup Emms. - - -File: emms.info, Node: Finding files and speed, Next: Setup Examples, Up: Configuration - -5.1 Finding files and speed -=========================== - -Emms needs to traverse directories in order to find playable media. The -default method Emms uses to achive this is -'emms-source-file-directory-tree-internal' as defined in -'emms-source-file.el'. 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). - - 'emms-source-file.el' defines another method for finding files, -'emms-source-file-directory-tree-find' which uses GNU/find. -'emms-source-file-directory-tree-find' is usually an order of magnitude -faster, but of course will not work if you do not have GNU/find -installed. - - The method Emms will use is defined in the customisable variable -EMMS-SOURCE-FILE-DIRECTORY-TREE-FUNCTION. - - -File: emms.info, Node: Setup Examples, Prev: Finding files and speed, Up: Configuration - -5.2 Setup Examples -================== - -What follow are samples from real-world Emms configurations which show -some of the variety and breadth of modifications people make to the -default Emms setup. - - The following excerpt includes dbus integration, defining a "recent" -filter for the *Note The Browser::, persistent playlist via -'emms-history.el', and enabling sending track information with -'emms-librefm-stream.el': - - ;; notifications - (require 'emms-dbus) - (emms-dbus-enable) - ;; covers - (setq emms-browser-covers #'emms-browser-cache-thumbnail-async) - (setq emms-browser-thumbnail-small-size 64) - (setq emms-browser-thumbnail-medium-size 128) - ;; filters - (emms-browser-make-filter "all" #'ignore) - (emms-browser-make-filter "recent" - (lambda (track) (< 30 - (time-to-number-of-days - (time-subtract (current-time) - (emms-info-track-file-mtime track)))))) - (emms-browser-set-filter (assoc "all" emms-browser-filters)) - ;; history - (emms-history-load) - ;; libre-fm - (emms-librefm-scrobbler-enable) - - In the following it is possible to see how some of defaults are set -regarding saving playlists, playlist interaction, as well as adding -special arguments to a specific player backend. - - (setq-default - emms-source-file-default-directory "/mnt/db/mediaCore/sound_music/" - - emms-source-playlist-default-format 'm3u - emms-playlist-mode-center-when-go t - emms-playlist-default-major-mode 'emms-playlist-mode - emms-show-format "NP: %s" - - emms-player-list '(emms-player-mpv) - emms-player-mpv-environment '("PULSE_PROP_media.role=music") - emms-player-mpv-parameters '("--quiet" "--really-quiet" "--no-audio-display" "--force-window=no" "--vo=null")) - - -File: emms.info, Node: Getting Help, Next: Formats and Freedom, Prev: Configuration, Up: Top - -6 Getting Help -************** - -If you have a bug to report, need help, or wish to suggest a feature, -please feel free to use the Emms mailing list.

To subscribe to it, visit -<http://lists.gnu.org/mailman/listinfo/emms-help>. - - If you are familiar with the Gmane service, there is a Gmane -newsgroup which mirrors this mailing address at gmane.emacs.emms.user. - - Emms also has a website at <http://www.gnu.org/software/emms/>. - - -File: emms.info, Node: Formats and Freedom, Next: Basic Commands, Prev: Getting Help, Up: Top - -7 Formats and Freedom -********************* - -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. - - Restrictive file formats put the corporate bottom-line before the -public interest. - - 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 <http://www.xiph.org/>. - - 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.

However, -Emms can be configured to utilize so-called "info methods" to augment -tracks with metadata information, such as artist name, track name, album -title, and the like. We describe these methods and their use in this -chapter. - - Fundamentally, info methods are Emacs Lisp functions that are called -for each track to provide information for that track. Current info -methods in Emms are restricted to tracks that are files; they do not -work with stream URLs (*note Streaming Audio::). Some of the methods -require installation of some additional software that Emms can then call -to read metadata from disk (*note Metadata Utilities::). Finally, some -methods work only with a limited set of media file formats such as Ogg -or MP3, while some methods support a wide variety of formats. - - If caching is enabled (it is by default) then the metadata for each -track will be stored in the cache for faster retrieval. That means if -you change info method and want updated tracks, you will have to reset -the cache 'M-x emms-cache-reset' and then repopulate with 'M-x -emms-add-directory-tree RET ~/Music/ RET' or similar. - - Automatic track information retrieval is enabled by default in the -'emms-all' setup level (*note Setup::). That setup level configures -Emms to use 'emms-info-native' and 'emms-info-cueinfo' methods, as they -are the only methods that do not rely on additional software. - - Here is a list of all info methods distributed with Emms and their -software requirements: - -'emms-info-native' - This method is implemented completely in Emacs Lisp and hence does - not require any external software. It supports Ogg Vorbis, Opus, - FLAC and MP3 files. - -'emms-info-tinytag' - This method utilizes a small Python library 'tinytag'. It supports - MP3, Ogg Vorbis, Opus, MP4, M4A, FLAC, WMA and WAV formats. - -'emms-info-exiftool' - This method calls 'exiftool' utility written in Perl. It supports - dozens of media file formats, far too many to list here. - -'emms-info-libtag' - This method calls a small "shim" executable 'emms-print-metadata' - built around TagLib library. It supports MP3, Ogg Vorbis, Opus, - FLAC, MPC, Speex, WavPack, TrueAudio, WAV, AIFF, MP4 and ASF - formats. - -'emms-info-metaflac' - This method calls 'metaflac' utility. It works only with FLAC - files. - -'emms-info-mp3info' - This method calls 'mp3info' utility. It works only with MP3 files - that have older id3v1 tags. - -'emms-info-ogginfo' - This method calls 'ogginfo' utility. It supports Ogg Vorbis and - Theora formats. - -'emms-info-opusinfo' - This method calls 'opusinfo' utility. It works only with Opus - files. - -'emms-info-cueinfo' - This is a special method that parses track information from an - accompanying cue file for FLAC and APE files (*note APE / FLAC - Commands::). It does not require any additional software. - - To use any of the methods, add the method to 'emms-info-functions' -list. For example: - - (require 'emms-info-native) - (add-to-list 'emms-info-functions 'emms-info-native) - -You can also use a combination of format-specific tools if needed: - - (require 'emms-info-mp3info) - (require 'emms-info-ogginfo) - (add-to-list 'emms-info-functions 'emms-info-mp3info 'emms-info-ogginfo) - -In this case both 'emms-info-mp3info' and 'emms-info-ogginfo' will be -called for each track. - - There are a number of user variables which control the behavior of -'emms-info': - - -- User Option: emms-info-auto-update - Non-nil when Emms should update track information if the file - changes. This will cause hard drive activity on track loading. If - this is too annoying for you, set this variable to nil. - - -- User Option: emms-info-asynchronously - Non-nil when track information should be loaded asynchronously. - This requires the feature 'later-do' which is provided by the file - 'later-do.el', which comes with Emms. See variable - 'emms-later-do-batch' for performance tweaking. - - -- User Option: emms-info-functions - A list of functions (info methods) which add information to tracks. - Each function is called with a track as argument. If two info - methods produce the same information (for example album name), the - latter one takes precedence. - -* Menu: - -* Metadata Utilities:: Supported external metadata utilities. -* Defining Info Methods:: How to define new info methods. - - -File: emms.info, Node: Metadata Utilities, Next: Defining Info Methods, Up: Track Information - -13.1 Metadata Utilities -======================= - -With the exception of 'emms-info-native' and 'emms-info-cueinfo', Emms -info methods require external metadata utilities to read metadata from -media files.

Info symbols -are keys that have an associated value stored in the "metadata cache". -While info symbols can have arbitrary names, the following symbols are -recognized by Emms: - -'info-album' - Album title. - -'info-albumsort' - Album title for collation. - -'info-artist' - Artist name. - -'info-artistsort' - Artist name for collation. - -'info-albumartist' - Album artist name. - -'info-albumartistsort' - Album artist name for collation. - -'info-composer' - Composer name. - -'info-composersort' - Composer name for collation. - -'info-date' - Release date. - -'info-originaldate' - Original release date. - -'info-performer' - Performer name. - -'info-title' - Track title. - -'info-titlesort' - Track title for collation. - -'info-tracknumber' - Track number. - -'info-discnumber' - Disc number. - -'info-year' - Release year. - -'info-originalyear' - Original release year. - -'info-note' - Free-form note. - -'info-genre' - Genre. - -'info-label' - Record label. - -'info-playing-time' - Playing time in seconds. - -An info method does not need to add all of these symbols into the given -track. It can also add other symbols, but those extra symbols won't be -used by Emms. - - We can for example look at the predefined method for retrieving -information about audio tracks in the Ogg format. The function -'emms-info-ogginfo' provided by 'emms-info-ogginfo.el' accepts an Emms -track TRACK as a single argument. It uses 'ogginfo' utility to extract -a list of key-value metadata pairs from the file represented by TRACK. -Next, it sets the appropriate info symbols for TRACK by calling -'emms-track-set'. Info symbols are interned from the extracted keys. -Those keys can be arbitrary strings, but they typically coincide with -the keys listed above; for example "album" and "artist" form info -symbols 'info-album' and 'info-artist'. - - -File: emms.info, Node: Interactive Playlists, Next: Markable Playlists, Prev: Track Information, Up: Top - -14 Interactive Playlists -************************ - -Emms provides a visual, interactive playlist mode as well as the ability -to use playlists without ever looking at then.

Definitions. - - "This License" refers to version 3 of the GNU General Public - License. - - "Copyright" also means copyright-like laws that apply to other - kinds of works, such as semiconductor masks. - - "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. - - 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. - - A "covered work" means either the unmodified Program or a work - based on the Program. - - 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. - - 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. - - 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. - - 1. Source Code. - - 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. - - 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. - - 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. - - 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. - - The Corresponding Source need not include anything that users can - regenerate automatically from other parts of the Corresponding - Source. - - The Corresponding Source for a work in source code form is that - same work. - - 2. Basic Permissions. - - 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. - - 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. - - Conveying under any other circumstances is permitted solely under - the conditions stated below. Sublicensing is not allowed; section - 10 makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - 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. - - 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. - - 4. Conveying Verbatim Copies. - - 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. - - 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. - - 5. Conveying Modified Source Versions. - - 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: - - a. The work must carry prominent notices stating that you - modified it, and giving a relevant date. - - b. 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". - - c. 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. - - d. 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. - - 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. - - 6. Conveying Non-Source Forms. - - 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: - - a. 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. - - b. 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. - - c. 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. - - d. 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. - - e. 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. - - 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. - - 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. - - "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. - - 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). - - 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. - - 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. - - 7. Additional Terms. - - "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. - - 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. - - 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: - - a. Disclaiming warranty or limiting liability differently from - the terms of sections 15 and 16 of this License; or - - b. 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 - - c. 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 - - d. Limiting the use for publicity purposes of names of licensors - or authors of the material; or - - e. Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f. 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. - - 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. - - 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. - - 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. - - 8. Termination. - - 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). - - 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. - - 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. - - 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. - - 9. Acceptance Not Required for Having Copies. - - 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. - - 10. Automatic Licensing of Downstream Recipients. - - 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. - - 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. - - 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. - - 11. Patents. - - 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". - - 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. - - 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. - - 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. - - 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. - - 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. - - 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. - - 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. - - 12. No Surrender of Others' Freedom. - - 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. - - 13. Use with the GNU Affero General Public License. - - 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. - - 14. Revised Versions of this License. - - 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. - - 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. - - 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. - - 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. - - 15. Disclaimer of Warranty. - - 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. - - 16. Limitation of Liability. - - 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. - - 17. Interpretation of Sections 15 and 16. - - 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. - - END OF TERMS AND CONDITIONS - -How to Apply These Terms to Your New Programs -============================================= - -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. - - 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. - ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES. - Copyright (C) YEAR NAME OF AUTHOR - - 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 - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU - 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 <http://www.gnu.org/licenses/>. - - Also add information on how to contact you by electronic and paper -mail. - - If the program does terminal interaction, make it output a short -notice like this when it starts in an interactive mode: - - PROGRAM Copyright (C) YEAR NAME OF AUTHOR - This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'. - This is free software, and you are welcome to redistribute it under certain conditions; type 'show c' for details. - - The hypothetical commands 'show w' and 'show c' 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". - - 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. For more information on this, and how to apply and follow -the GNU GPL, see <http://www.gnu.org/licenses/>. - - 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 first, -please read <http://www.gnu.org/philosophy/why-not-lgpl.html>. - - -File: emms.info, Node: The GNU FDL, Next: Concept Index, Prev: Copying, Up: Top - -31 GNU Free Documentation License -********************************* - - Version 1.2, November 2002 - - Copyright (C) 2000,2001,2002 Free Software Foundation, Inc. - 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA - - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - 0. PREAMBLE - - The purpose of this License is to make a manual, textbook, or other - functional and useful document "free" 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. - - 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. - - 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. - - 1. APPLICABILITY AND DEFINITIONS - - 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. - - 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. - - 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. - - 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. - - 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. - - 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". - - Examples of suitable formats for Transparent copies include plain - ASCII without markup, Texinfo input format, LaTeX input format, - SGML or XML using a publicly available DTD, and standard-conforming - simple HTML, PostScript or PDF designed for human modification. - Examples of transparent image formats include PNG, XCF and JPG. - Opaque formats include proprietary formats that can be read and - edited only by proprietary word processors, SGML or XML for which - the DTD and/or processing tools are not generally available, and - the machine-generated HTML, PostScript or PDF produced by some word - processors for output purposes only. - - 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. - - 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. - - 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. - - 2. VERBATIM COPYING - - 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. - - You may also lend copies, under the same conditions stated above, - and you may publicly display copies. - - 3. COPYING IN QUANTITY - - 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. - - 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. - - 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. - - 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. - - 4. MODIFICATIONS - - 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: - - A. 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. - - B. 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. - - C. State on the Title page the name of the publisher of the - Modified Version, as the publisher. - - D. Preserve all the copyright notices of the Document. - - E. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. - - F. 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. - - G. Preserve in that license notice the full lists of Invariant - Sections and required Cover Texts given in the Document's - license notice. - - H. Include an unaltered copy of this License. - - I. 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. - - J. 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. - - K. 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. - - L. 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. - - M. Delete any section Entitled "Endorsements". Such a section - may not be included in the Modified Version. - - N. Do not retitle any existing section to be Entitled - "Endorsements" or to conflict in title with any Invariant - Section. - - O. Preserve any Warranty Disclaimers. - - 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. - - 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. - - 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. - - 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. - - 5. COMBINING DOCUMENTS - - 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. - - 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. - - 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." - - 6. COLLECTIONS OF DOCUMENTS - - 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. - - 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. - - 7. AGGREGATION WITH INDEPENDENT WORKS - - 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. - - 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. - - 8. TRANSLATION - - 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. - - 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. - - 9. TERMINATION - - 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. - - 10. FUTURE REVISIONS OF THIS LICENSE - - 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 - <http://www.gnu.org/copyleft/>. - - 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 following the terms and conditions either of - that specified version or of any later version that has been - published (not as a draft) by the Free Software Foundation. If the - Document does not specify a version number of this License, you may - choose any version ever published (not as a draft) by the Free - Software Foundation. - -31.1 ADDENDUM: How to use this License for your documents -========================================================= - -To use this License in a document you have written, include a copy of -the License in the document and put the following copyright and license -notices just after the title page: - - Copyright (C) YEAR YOUR NAME. - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.2 - or any later version published by the Free Software Foundation; - with no Invariant Sections, no Front-Cover Texts, and no Back-Cover - Texts. A copy of the license is included in the section entitled ``GNU - Free Documentation License''. - - If you have Invariant Sections, Front-Cover Texts and Back-Cover -Texts, replace the "with...Texts." line with this: - - with the Invariant Sections being LIST THEIR TITLES, with - the Front-Cover Texts being LIST, and with the Back-Cover Texts - being LIST. - - If you have Invariant Sections without Cover Texts, or some other -combination of the three, merge those two alternatives to suit the -situation. - - If your document contains nontrivial examples of program code, we -recommend releasing these examples in parallel under your choice of free -software license, such as the GNU General Public License, to permit -their use in free software. - - -File: emms.info, Node: Concept Index, Next: Function Index, Prev: The GNU FDL, Up: Top - -Concept Index -************* - - -* Menu: - -* adding functionality: Hooks.
