[VM] Programmer's guide to VM code?

[Konrad Hinsen]

I wonder if there is any useful documentation for those who wish to
write e-lisp code that manipulates VM buffers. For example, I have
spent some time trying to figure out how to get the presentation
buffer for the active folder, but so far without success. I don't
expect a full manual, but perhaps there are some notes, discussions
on this list, etc. that could help.
