I didn't find anything suitable in the CNEWS distribution, so I wrote
my own in PERL.  Care is taken to generate a somewhat meaningful Path:
line, and to undo some common forms of address rot (most of the code
is reused from my never completed archive server).

Use it in aliases like this:
in-sun-managers:"|/usr/lib/news/receive mail.sun-managers"

You can even cross-post mailing lists to multiple groups, though I
don't know why I did that other than it was easy...
