INSTALL

+                       Music Player Daemon (MPD) - INSTALL
+
+Requirements
+------------
+
+libao - http://www.vorbis.com/download_unix.psp
+(This comes with most/all distributions. Make sure you have both
+the ao libs and development packages for your distribution installed.
+For Red Hat 8.0, the necessary packages are: libao and libao-devel)
+
+zlib - http://www.gzip.org/zlib
+(This comes with all distributions.  Make sure you have bot the zlib libs
+and development packages for your distribution installed.  For Red hat,
+the necessary packages are: zlib and zlib-devel)
+
+Optional
+--------
+
+Ogg Vorbis - http://www.xiph.org/ogg/vorbis/
+(This comes with most/all distributions.  Make sure you have both the
+ogg and vorbis libs as well as the development packages for your
+distribution installed.  For Red Hat 8.0, the necessary packages are:
+libogg, libogg-devel, libvorbis, and libvorbis-devel).
+
+Flac - http://flac.sf.net
+For Flac support, you need Flac 1.1.0 or greater.
+
+Download
+--------
+
+Get the latest release from of MPD from http://www.musicpd.org
+
+Compile
+-------
+
+1) unzip and untar the archive
+
+$ tar zxvf mpd-x.x.x.tar.gz
+
+2) change to directory created
+
+$ cd mpd-x.x.x
+
+3) Run configure script (this will determine what dependencies you have)
+
+$ ./configure
+
+4) Compile
+
+$ make
+
+Install (Optional)
+-------
+
+(as root)
+$ make install
+
+Run
+---
+
+1) run mpd:
+<port>: port number daemon listens on (if running as a user, this should be 
+	greater than 1024)
+<mp3 directory>:  directory containing mp3's
+<playlist directory>: directory where playlists will be stored (and .mpddb will
+	be placed)
+<mpd log>: log file for mpd
+<mpd err>: error log file for mpd
+
+$ mpd <port> <mp3 directory> <playlist directory> <mpd log> <mpd err>
+
+example where mpd executable is in mpd-x.x.x directory:
+$ mpd-x.x.x/mpd 2100 mp3 playlists mpd.log mpd.err
+
+Note: The first time you run mpd, it will "explore" your mp3 directory for
+mp3's.
+
+Also, mpd can alternatively use config file.  In this case,
+run mpd like this:
+
+$ mpd <config file>
+
+(if no config file is specified, mpd's looks for ~/.mpdconf then /etc/mpd.conf)
+
+an example would be:
+
+$ mpd playlists/.mpdconf
+
+A sample config file is included with the source of MPD, mpdconf.example .
+
+Using MPD
+---------
+
+You can download a web interface (phpMp) to MPD at 
+http://www.musicpd.org .
+
+Also, several other clients can be found for MPD at http://www.musicpd.org .
+
+MPD can be interfaced directly using telnet (see COMMANDS, if you are brave).

+                          Music Player Daemon (MPD)
+                        http://www.musicpd.org
+
+A daemon for playing music (mp3, ogg vorbis, and flac).  Music is played
+through the server's audio device.  The daemon stores info about all available
+music, and this info can be easily searched and retrieved.  Player control, info
+retrieval, and playlist management can all be managed remotely.
+
+To install MPD, see INSTALL.
+
+MPD includes 2 libraries in the source. libid3tag and libmad are released under
+the GPL and copyrighted by Robert Leslie (http://www.underbit.com/products/mad).

TODO

+1) 24-bit pcm-tools (this may just wait since almost no one uses it)
+2) put software mixer settings in state file
+3) finish modifying man page, commands, and example config file

UPGRADING

+                       Music Player Daemon (MPD) - UPGRADING
+
+Upgrading to 0.9.3
+------------------
+
+Wave support was added, so to have your wave files added, update the db (mpc
+update).  
+
+Also, song lengths are now stored in the db.  To get this stuff
+added to the db, you will need to recreate the db from scratch.  To do this,
+run mpd with the "--create-db" commandline option. 
+
+Upgrading to 0.9.0
+------------------
+
+The "stop_on_error" config parameter was removed, so be sure to remove this
+parameter from your config file.
+
+Upgrading to 0.8.x
+------------------
+
+If you have FLACs, then to have them added to your list of available music,
+just use "update".
+
+Upgrading from 0.5.x to 0.6.x
+-----------------------------
+If you have not compiled MPD with "make ogg", then nothing is needed.
+
+If you compiled with "make ogg", just use "update" (available via the phpMp
+interface) to add your OGGs to MPD's list of available music.

+.TH "Music Player Daemon" 1
+.SH NAME
+MPD \- A daemon for playing music (mp3, ogg vorbis, and flac)
+.SH SYNOPSIS
+.B mpd
+.RI [ options ]
+.RI [ CONF_FILE ]
+.br
+.B mpd
+.RI [ options ]
+.I PORT MUSIC_DIR PLAYLIST_DIR LOG_FILE ERROR_FILE 
+.br
+.SH DESCRIPTION
+MPD is a daemon for playing music (mp3, ogg vorbis, and flac).  Music is played
+through the server's audio device.  The daemon stores info about all available
+music, and this info can be easily searched and retrieved.  Player control, info
+retrieval, and playlist management can all be managed remotely.
+
+MPD searches for a config file in ~/.mpdconf then /etc/mpd.conf or uses
+CONF_FILE.  Instead of using a config file, the minimal configuration paramters
+can be specified on the command line: PORT, MUSIC_DIR, PLAYLIST_DIR, LOG_FILE,
+ and ERROR_FILE.
+
+Read more about MPD on http://www.musicpd.org
+.SH OPTIONS
+.TP
+.B --create-db
+(Re)Crete the db file for mpd.
+.TP
+.BI --help
+Output a brief help message.
+.br
+.TP
+.BI --no-daemon
+Don't detach from console or redirect output to log files.
+.TP
+.BI --verbose
+Output verbose amounts of information to the logs
+.TP
+.BI --version
+Print version information.
+.SH PARAMETERS
+Below are a list of parameters that can be specified in the config file.  Each line in the config file should be of the form:
+.br
+parameter "value"
+.TP
+.B port <port>
+This specifies the port that MPD listens on. This parameter is required. This is typically 2100.
+.TP
+.B music_directory <directory>
+This specifies the directory where music is located.  This parameter is required.  The directory path should be an absolute path.
+.TP
+.B playlist_directory <directory>
+This specifies the directory where saved playlists are stored.  This parameter is required.  The directory path should be an absolute path.
+.TP
+.B log_file <file>
+This specifies where the log file should be located.  This parameter is required.  The file path should be an absolute path.
+.TP
+.B error_file <file>
+This specifies where the error file should be located.  This parameter is required.  The file path should be an absolute path.
+.TP
+.B log_level <default, secure, or verbose>
+This specifies how verbose logs are.  "default" is minimal logging, "secure" reports from what address a connection is opened, and when it is closed, and "verbose" records excessive amounts of information for debugging purposes.  The default is "default".
+.TP
+.B db_file <file>
+This specifies where the db file will be stored.  The file path should be an
+absolute path.  The default is ".mpddb" in the playlist directory.
+.TP
+.B filesystem_charset <charset>
+This specifies the character set  used for the filesystem.  A list of supported
+character sets can be obtained by running "iconv -l".  The default is
+determined from the locale when the db was originally created.
+.TP
+.B bind_to_address <ip address or hostname or any>
+This specifies which address MPD binds to and listens on.  The default is "any",
+which binds to all available addresses.
+.TP
+.B user <user>
+This specifies the user that mpd will run as, if set.
+.TP
+.B password <password@permissions>
+This specifies a password for access to mpd.  The format is 
+"password@permissions" where permissions is a comma delimmitted list composed
+of "read","add","control", and/or "admin".  "read" allows for reading of
+the database, displaying the current playlist, and current status of mpd.
+"add" allows for adding songs and loading playlists.  "control" allows
+for all other player and playlist manipulations.  "admin" allows the db
+to be updated and for the client to kill mpd.  More than one password can
+be specified.  An example of a password is "somePassword@read,add".
+.TP
+.B default_permissions <permissions>
+This specifies the permissions of a client that has not been authenticated using
+a password.  The format of permissions is specified n the description of the 
+"password" config paramter.  If not passwords are specified, the default is 
+"read,add,control,admin", otherwise it is "" (no permissions).
+.TP
+.B state_file <file>
+This specifies if a state file is used and where it is located.  The file path should be an absolute path.  The state of mpd will be saved to this file when mpd is terminated by a TERM signal or by the "kill" command.
+.TP
+.B connection_timeout <seconds>
+If a client does not send any new data in this time period, the connection is closed. The default is 60 seconds.
+.TP
+.B max_connections <int>
+This specifies the maximum number of clients that can be connected to MPD. The default is 5 connections.
+.TP
+.B mixer_type <oss or alsa>
+This specifies which mixer to use. The default is oss.
+.TP
+.B mixer_device <mixer dev>
+This specifies which mixer to use. The default for oss is /dev/mixer;
+the default for alsa is "hw:0".
+.TP
+.B mixer_control <string>
+This specifies which mixer control to use (sometimes referred to as the "device").  Examples of mixer controls are PCM, Line1, Master, etc.  An example for OSS is "Pcm", and an example for alsa is "PCM".
+.TP
+.B max_playlist_length <int>
+This specifies the maximum number of songs that can be in the playlist. The default is 4096 songs.
+.TP
+.B buffer_size <size in KB>
+This specifies the size of the buffer that mpd uses.  The default is 2048 kilobytes.
+.B buffer_before play <0-100%>
+This specifies the amount of buffer that will be filled before a song begins playing. The default is 25%.
+.TP
+.B max_command_list_size <size in KB>
+This specifies the maximum size a command list can be (in kilobytes). The default is 2048 kilobytes.
+.TP
+.B max_output_buffer_size <size in KB>
+This specifies the maximum size of the output buffer to a client (in kilobytes).
+The default is 2048 kilobytes.
+.TP
+.B ao_driver <ao plug-in>
+This specifies the ao plug-in to use for audio output.  Typical values for
+Linux include "oss" and "alsa09".  The default value is "default".
+.TP
+.B ao_driver_options <ao plug-in options>
+This specifies the options to use for the selected ao_driver.  For oss, the
+only option available is "dsp".  For alsa09, the available options are:
+"dev", "buf_size", and "periods".  Options are assigned using "=" and ";" is
+used to separate options.  An example for oss: "dsp=/dev/dsp".  An example for
+alsa09: "dev=hw:0,0;buf_size=4096".  The default value is "".
+.TP
+.B audio_write_size <size in bytes>
+This specifies how many bytes mpd writes to the audio device at once. The
+default is 1024.  This options is to work around a bug in older versions
+of libao on sound cards with very small buffers.
+.TP
+.B save_absolute_paths_in_playlists <yes or no>
+This specifies whether relative or absolute paths for song filenames are
+used when saving playlists.  The default value is "no".

+
+ libid3tag - ID3 tag manipulation library
+ Copyright (C) 2000-2003 Underbit Technologies, Inc.
+
+ $Id: CHANGES,v 1.1 2003/08/14 03:57:13 shank Exp $
+
+===============================================================================
+
+Version 0.15.0 (beta)
+
+  * Updated to autoconf 2.57, automake 1.7.5, libtool 1.4.3.
+
+  * Added new id3_tag_version(), id3_tag_options(), id3_tag_setlength(),
+    id3_frame_field(), id3_field_getlatin1(), id3_field_getfulllatin1(),
+    id3_genre_index(), id3_genre_number(), id3_latin1_ucs4duplicate(),
+    id3_utf16_ucs4duplicate(), and id3_utf8_ucs4duplicate() API routines.
+
+  * Properly exposed the id3_frame_new(), id3_frame_delete(), and
+    id3_field_type() API routines.
+
+  * Fixed a possible segmentation fault rendering ID3v1 tags when a tag
+    field exceeds the field length limit.
+
+  * Fixed a problem whereby the file interface could try to seek and read
+    data from a non-seekable stream, unrecoverably losing data from the
+    stream. (N.B. the fix does not work under Win32.)
+
+  * Fixed a problem reading ID3v2.2 frames which corrupted their frame IDs
+    and caused them not to be re-rendered.
+
+  * Improved rendering of the ID3v1 genre field from ID3v2 genre
+    names/numbers. The genre "Other" is used in place of non-translatable
+    genres.
+
+  * Rendering an empty ID3v1 tag now properly returns 0 length even when a
+    null buffer pointer is passed.
+
+  * Changed the file implementation to maintain information about present
+    but unparseable tags, instead of ignoring all tags and returning an
+    error.
+
+  * Added an external dependency on zlib (libz), which is no longer
+    included.
+
+  * Changed to build a shared library by default.
+
+  * Changed to use native Cygwin build by default; give --host=mingw32 to
+    `configure' to use MinGW (and avoid a dependency on the Cygwin DLL).
+
+Version 0.14.2 (beta)
+
+  * Changed Cygwin builds to use MinGW; resulting Win32 executables no
+    longer have a dependency on Cygwin DLLs.
+
+Version 0.14.1 (beta)
+
+  * Updated config.guess and config.sub to latest upstream versions.
+
+  * Enabled libtool versioning rather than release numbering.
+
+  * Renamed `libid3' to `libid3tag' and enabled installation as a separate
+    library.
+
+  * Several other small fixes.
+
+Version 0.14.0 (beta)
+
+  * Added a new ID3 tag manipulation library (libid3). The required zlib
+    support is provided either by the host system or by the included static
+    library implementation (libz).
+
+  * Improved MSVC++ portability and added MSVC++ project files.

src/libid3tag/INSTALL

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+
+===============================================================================
+
+INTRODUCTION
+
+  libid3tag is a library for reading and (eventually) writing ID3 tags, both
+  ID3v1 and the various versions of ID3v2.
+
+  See the file `id3tag.h' for the current library interface.
+
+  This package uses GNU libtool to arrange for zlib to be linked
+  automatically when you link your programs with this library. If you aren't
+  using GNU libtool, in some cases you may need to link with zlib
+  explicitly:
+
+      ${link_command} ... -lid3tag -lz
+
+===============================================================================
+
+BUILDING AND INSTALLING
+
+  Note that this library depends on zlib 1.1.4 or later. If you don't have
+  zlib already, you can obtain it from:
+
+      http://www.gzip.org/zlib/
+
+  You must have zlib installed before you can build this package.
+
+Windows Platforms
+
+  libid3tag can be built under Windows using either MSVC++ or Cygwin. A
+  MSVC++ project file can be found under the `msvc++' subdirectory.
+
+  To build libid3tag using Cygwin, you will first need to install the Cygwin
+  tools:
+
+      http://www.cygwin.com/
+
+  You may then proceed with the following POSIX instructions within the
+  Cygwin shell.
+
+  Note that by default Cygwin will build a library that depends on the
+  Cygwin DLL. You can use MinGW to build a library that does not depend on
+  the Cygwin DLL. To do so, give the option --host=mingw32 to `configure'.
+  Be certain you also link with a MinGW version of zlib.
+
+POSIX Platforms (including Cygwin)
+
+  The code is distributed with a `configure' script that will generate for
+  you a `Makefile' and a `config.h' for your platform. See the file
+  `INSTALL' for generic instructions.
+
+  The specific options you may want to give `configure' are:
+
+      --disable-debugging       do not compile with debugging support, and
+                                use more optimizations
+
+      --disable-shared          do not build a shared library
+
+  By default the package will build a shared library if possible for your
+  platform. If you want only a static library, use --disable-shared.
+
+  If zlib is installed in an unusual place or `configure' can't find it, you
+  may need to indicate where it is:
+
+      ./configure ... CPPFLAGS="-I${include_dir}" LDFLAGS="-L${lib_dir}"
+
+  where ${include_dir} and ${lib_dir} are the locations of the installed
+  header and library files, respectively.
+
+Experimenting and Developing
+
+  Further options for `configure' that may be useful to developers and
+  experimenters are:
+
+      --enable-debugging        enable diagnostic debugging support and
+                                debugging symbols
+
+      --enable-profiling        generate `gprof' profiling code
