  * Creative Voice File Demuxer by Mike Melanson (melanson@pcisys.net)
+ * Note that this demuxer does not yet support very many things that can
+ * possibly be seen in a VOC file. It only plays the first block in a file.
+ * It will only play that block if it is PCM data. More variations will be
+ * supported as they are encountered.
