I had some free time today so I reversed the VirtualVolume format:
http://sirg3.svnrepository.com/RbHacks/trac.cgi/wiki/VirtualVolume
Also, for the sake of it being recorded in the archives, the format
is also below. It's in a pseudo-C++, which probably isn't too clear,
so if you have questions, ask! Just remember, this is gathered from
reverse engineering, so it's NOT OFFICIAL and NOT SUPPORTED.
