Play .ogg audio files in iTunes

The audio compression codec OggVorbis is not massively used, but it still is a rather good codec.
If you wish to play .ogg audio encoded files directly in iTunes or with QT7, there is a small plug-in that can be found from the following website:

It is not fully finalized, there is still a bug preventing iTunes to read the title of the songs.
