Prerequisites
This extension uses LilyPond to render score images, so you need a working LilyPond installation. If you want the extension to trim the score files for you, you will also need ImageMagick.

The extension is also capable of creating Ogg/Vorbis files from the MIDI files generated by LilyPond. If you want to make use of this functionality, you need to have Extension:OggHandler installed.

Version 0.1 of this extension was tested with MediaWiki 1.18.0 and LilyPond 2.12.3. The current SVN snapshot might require a newer version of MediaWiki and/or LilyPond.

Download instructions
