     I use this script from my crontab to update my maps.  (Note
that I have some things in non-standard places.)  This system does
keep both the news articles and the unpacked maps around, but I
don't regard that as a problem.  I run expire several times each
night (I know, get C news expire), and comp.mail.maps gets cleaned
out when it reaches 3 days old.

     The "make install" at the end runs pathalias, and formats the
results for smail.  I haven't had to touch my mail maps for about
6 months.  Have fun,

#!/bin/sh
# This script will extract the new maps received in comp.mail.maps.
# It uses the file "Last_Maps_Extracted" to keep track of when it
# last updated the maps.  All articles in comp.mail.maps newer than
# that file are unshar-ed.
#
# If no files were produced by the unshar, then we quit.
# If there were files, we mail "news" a report of what was received.
# Then we move those maps to our path map directories MAP_U and
# MAP_D.  Finally, we build and install a new path file.
