* \mainpage TagLib
*
* \section intro Introduction
*
* TagLib is a library for reading and editing audio meta data, commonly know as \e tags.
*
* Features:
* - A clean, high level, C++ API to handling audio meta data.
* - Format specific APIs for advanced API users.
* - ID3v1, ID3v2, APE, FLAC, Xiph, iTunes-style MP4 and WMA tag formats.
* - MP3, MPC, FLAC, MP4, ASF, AIFF, WAV, TrueAudio, WavPack, Ogg FLAC, Ogg Vorbis, Speex and Opus file formats.
* - Basic audio file properties such as length, sample rate, etc.
* - Long term binary and source compatibility.
* - Extensible design, notably the ability to add other formats or extend current formats as a library user.
* - Full support for unicode and internationalized tags.
* - Dual <a href="http://www.mozilla.org/MPL/MPL-1.1.html">MPL</a> and
* <a href="http://www.gnu.org/licenses/old-licenses/lgpl-2.1.html">LGPL</a> licenses.
* - No external toolkit dependancies.
*
* \section why Why TagLib?
*
* TagLib originally was written to provide an updated and improved ID3v2 implementation in C++ for use
* in a variety of Open Source projects. Since development began in 2002 and the 1.0 release in 2004
* it has expanded to cover a wide variety of tag and file formats and is used in a wide variety of
* Open Source and proprietary applications. It now supports a variety of UNIXes, including Apple's OS
* X, as well as Microsoft Windows.
*
* \section commercial Usage in Commercial Applications
*
* TagLib's licenses \e do allow usage within propriety (\e closed) applications, however TagLib is \e not
* public domain. Please note the requirements of the LGPL or MPL, and adhere to at least one of them.
* In simple terms, you must at a minimum note your usage of TagLib, note the licensing terms of TagLib and
* if you make changes to TagLib publish them. Please review the licenses above before using TagLib in your
* software. Note that you may choose either the MPL or the LGPL, you do not have to fulfill the
* requirements of both.
*
* \section installing Installing TagLib
*
* Please see the <a href="http://developer.kde.org/~wheeler/taglib.html">TagLib website</a> for the latest
* downloads.
*
* TagLib can be built using the CMake build system. TagLib installs a taglib-config and pkg-config file to
* make it easier to integrate into various build systems. Note that TagLib's include install directory \e must
* be included in the header include path. Simply adding <taglib/tag.h> will \e not work.
*
* \section start Getting Started
*
* TagLib provides both simple, abstract APIs which make it possible to ignore the differences between tagging
* formats and format specific APIs which allow programmers to work with the features of specific tagging
* schemes. There is a similar abstraction mechanism for AudioProperties.
*
* The best place to start is with the <b>Class Hierarchy</b> linked at the top of the page. The File and
* AudioProperties classes and their subclasses are the core of TagLib. The FileRef class is also a convenient
* way for using a value-based handle.
*
* \note When working with FileRef please consider that it has only the most basic (extension-based) file
* type resolution. Please see its documentation on how to plug in more advanced file type resolution. (Such
* resolution may be part of later TagLib releases by default.)
*
* Here's a very simple example with TagLib:
*
* \code
*
* TagLib::FileRef f("Latex Solar Beef.mp3");
* TagLib::String artist = f.tag()->artist(); // artist == "Frank Zappa"
*
* f.tag()->setAlbum("Fillmore East");
* f.save();
*
* TagLib::FileRef g("Free City Rhymes.ogg");
* TagLib::String album = g.tag()->album(); // album == "NYC Ghosts & Flowers"
*
* g.tag()->setTrack(1);
* g.save();
*
* \endcode
*
* More examples can be found in the \e examples directory of the source distribution.
