I use uuhosts to unpack the maps, and rebuild whenever any new maps
come in.  I ignore generally ignore news.config updates, but I read
them so that if someone complains about email problems, I have an
idea where to look.

Here's the first part of the script that's run nightly out of cron.
I particularly like the "elif echo ..." line.
	/r$

#! /bin/sh -vx
##  Script to build UUCP maps if the uuhosts Index file has been modified.
##  This script is in three major sections, each with its own config data.

##
##  PROLOG SECTION
##
PATH=/usr/uucp/bin:/usr/local/bin:/usr/ucb:/bin:/usr/bin: ; export PATH

##  Capture output.
if [ "$1" = "" ] ; then
    exec >/usr/uucp/bin/make-uucp-maps.out 2>&1
fi
cd /usr/spool/ftp/uumap/comp.mail.maps
echo "Started map script on `date`."

##  Ensure the index file exists; if it does, and it's new, make new maps.
uuhosts -unbatch
if [ ! -r Index ] ; then
    echo "Rebuilding uuhosts index file."
    uuhosts -i
elif echo "COSTS PATHS: Index; @/bin/false" | make -qf - ; then
    exec echo "No new map data."
fi


##
##  PATHALIAS SECTION
##
echo "Starting pathalias on `date`."

##  Dead machines and links.
DEAD=""

##  Overloaded machines and links.
AVOID=""

##  Debugging.
TRACE=""
DEBUG="-vvv ${TRACE}"

##  The path files.  First read local updates like u.BBN, then read the
##  domain files, then the raw map files.
P1="u.[A-Z]*"
P2="d.*"
P3="u.[a-z]*"
PATHS="${P1} ${P2} ${P3}"

##  Crunch, crunch
pathalias -i -c ${DEBUG} ${DEAD} ${AVOID} ${PATHS} |\
	awk '{ printf "%s\t%s\t%s\n", $2, $1, $3 }' >COSTS
awk '{ printf "%s\t%s\n", $1, $3 }' <COSTS >PATHS
sort +1.0 -n -o COSTS COSTS
sort -f -o PATHS PATHS
