+------------------------ From the README file ------------------------
+This software is completely useless to 99.99 percent of users
+out there. It is mostly of use to those interested in audio
+coding research and evaluating codecs. It could theoretically
+be used as a portion of a DVD playback system for unix systems. 
+There are issues with DVD encryption and licensing that need to be
+resolved however.
