* This is a minimalistic implementation of the Xing VBR headers. Xing
* headers are often added to VBR (variable bit rate) MP3 streams to make it
* easy to compute the length and quality of a VBR stream. Our implementation
* is only concerned with the total size of the stream (so that we can
* calculate the total playing time and the average bitrate). It uses
* <a href="http://home.pcisys.net/~melanson/codecs/mp3extensions.txt">this text</a>
* and the XMMS sources as references.
