Please don't reply directly, this is a mailing list, ask and answer there.

And yes, I misunderstood.

AFAIR c-news use a similar, but not identical, spool layout, to that of 
Leafnode.  (It has been a few decades since I compiled c-news, much 
longer for b-news.)

Linking the various "base" message directories - comp, alt, rec, etc. - 
from the c-news $NEWSSPOOL into the Leafnode spool directory should work.

So if $NEWSSPOOL is /news, and Leafnode is configured 
"--with-spooldir=/leafnode/", then "ln -s /news/comp /leafnode" and so 
on should do the right thing.

That covers reading messages...

The out.going directory in Leafnode is different, it is where out going 
messages are placed, not newsbatches.

Hmm, inews should be able to read and inject the messages, so a cron job 
that ran inews on each (munged - remove headers that c-news will add 
itself) file in /leafnode/out.going and then deleted it on success every 
now and then should do the job.

I think, if the only Leafnode binary that is run is leafnode, it is doable.
