Umm, apologies for being dense, but why Would you want one...?
Why not use Leafnode or pnews/suck [if you don't want to muck about
setting up a full blown INN install] or an equivalent and use your
favourite Unix newsreader, say trn, to read from the resulting
local spool...?
DISCLAIMER: Of course I have never used Linux or any other Unix-type
OS in my _entire_ life (-;
