I did the context diffs for C news 1.5.5.  I advise that you ignore the
sources in the C news distribution, as they are for 1.5 (which Geoff is
still running).  The safest course of action is for you to get nntp 1.5.5
from neat.ai.toronto.edu (128.100.1.65) and to get the C news diffs from
there as well.  Unpack, unshar the shar file to create batch.c, and apply
the diffs with patch.  You will have a vanilla 1.5.5.C that you can customize
for your site.

The rest of the installation is exactly like 1.5.5.  You should specify the
location of the list of articles in your sys file to match what your nntpsend
expects.

If you want, you can use the enclosed nntpsend, which locks things "C news
style" and does not rely on the file of article paths "cooling off" like
nntpsend currently does.  It also assumes that the lists of articles togo are
under spool/out.going like the rest of C news batching does.  I chose that
over doing a "vianntp" batcher because I prefer running nntpsend
independently.  You can run as many of those nntpsends at the same time
as you wish, they lock properly.  I even had them running after each 
relaynews for an afternoon...

I have also enclosed our sys file, should you need an example.
