02/01/2004: MP3SPI 1.8
----------------------
 Initial official release. It targets J2SE 1.3 and J2SE 1.4.

 It includes a workaround to get audio properties (duration, title, author, bitrate, 
 vbr, ...) that will be available in JDK 1.5. It provides "static" MP3 format properties
 such as (mp3.version.mpeg, mp3.version.layer, mp3.id3tagv2, ...). The mp3.id3tagv2
 property allows to get all ID3v2 frames. MP3SPI also provides "dynamic" MP3 properties
 for each frame played such as (mp3.frame , mp3.frame.bitrate, mp3.frame.size.bytes, 
 mp3.equalizer, ...). The mp3.equalizer property allows to have equalizer feature.

Notes :
-----
 MP3SPI needs JLayer and Tritonus libraries to work.
