Well, I took that statement to heart and started digging into the source
code (hoping I would be able to understand it)
While I haven't given up yet, code at this level looks pretty magic to
me. I haven't even figured out where to start tweaking yet. Basically
what I'm asking is for any references to get me started on understanding
the vinum code. At a low level it seems pretty well documented, but I'm
looking for a broader explanation. Something like "File xxx.c contains
routines for foo, file yyy.c contains routines for doing bar."
This is not guarantee that I'm at the point where I can figure this out.
But as I said before, I'm not ready to give up yet.

TIA
-Bill
