Geoff has already done a sample port of NN to use his libnov code. nnmaster
is dead.

I'm looking at it at this very moment...

As a short term solution, NN is probably going to inherit Geoff's code
and a big mess of #ifdef's.

In the long term, NN will most likely *only* use libnov.  By then, libnov
will be either transparent to things like NNTP, or will be hacked to be
transparent. [Rich Salz has already provided me with a neat 'hack'].

NNMASTER will be gone for those who can get the .overview files maintained 
by their news system.  For those who cannot, there will be an equivalent
of NNmaster, but writing files in .overview format rather than nn's private
way.  Other newsreaders will be able to share the new-nnmaster's database.

However, I'm going on holidays for 2 weeks as of tomorrow....
