leafnode filterfile

As an example of how to use a leafnode filterfile here's how to set up leafnode to block posts which are cross posted to another news group.

To take one at random let's use uk.rec.mensa. You add a line to your leafnode config file which reads:

filterfile = /etc/news/leafnode/filters

and then in /etc/news/leafnode/filters you will need:

^Newsgroups:.*[, ]uk\.rec\.mensa$
^Newsgroups:.*[, ]uk\.rec\.mensa,

It's as simple as that.
