I was using plain old 'sh' to crack open the articles, until someone
pointed out that this was a dangerous procedure. Now I use "unsharmap",
which comes from the smail3.1 distribution.

I leave the lcasep, pathalias, and unsharmap executables in my
/pub/lib/maps directory. There, I also have a script which is run nightly
from root's crontab:

	: remap -- if new articles are in 'list', extract and process

	[ -s list ] &&
	{ unsharmap < list > log 2> error
	  mv list list.o ; } ||
	exit

	pathalias -i d* u.* | lcasep | sort -o paths
	chgrp uucp paths
	chown uucp paths

	mv paths /usr/lib/uucp/paths

The "list" file is created by this line in /usr/lib/news/sys:

	map:comp.mail.maps/all:F:/pub/lib/maps/list

Since I extract every twenty-four hours, I force the map articles
to expire that fast too.
