Untangling this code is murder.

vorbis/tremor depends on so many internal details of libogg that I'm 
going nuts trying to untangle the two.  In addition, the vorbis and 
tremor codebases have diverged from bug fixes as well as the difference 
in functionality focus.

Does anybody have regression tests for libvorbis/libogg/libtremor? 
Untangling this would be a lot easier if I could run a test against each 
change to ensure that I haven't hosed something.

Thanks,
