/*
* Implementation file for mp3 scanner and monitor
*
* Ironically, this now scans file types other than mp3 files,
* but the name is the same for historical purposes, not to mention
* the fact that sf.net makes it virtually impossible to manage a cvs
* root reasonably. Perhaps one day soon they will move to subversion.
