>Description:
	It would be convenient if we have a periodic(8) script that ran
	sa-update nightly, allowing new rules to be downloaded automatically.
>How-To-Repeat:
	n/a
>Fix:
	Below is the script.  Note that the hard-coded /usr/local paths will
	need to be changed to %%WHATEVER%% and expanded.  (I'm being somehwat
	lazy tonight, otherwise I'd include a full diff/patch for the port
	Makefile and related stuffs)

	periodic flags used are fairly self-descriptive.  :-)



#!/bin/sh -f
#
# $FreeBSD$
#
# periodic(8) script that runs sa-update on a nightly basis, updating
# SpamAssassin rules if needed.  Relies on sa-update command.
#
# Contributed by: Jeremy Chadwick <koitsu at FreeBSD.org>
#
# Define these variables in either /etc/periodic.conf or
# /etc/periodic.conf.local to override the defaults.
#
# Examples:
#
# saupdate_enable="YES"		# run sa-update(1) daily
# saupdate_flags="--nogpg"	# flags passed to sa-update, e.g. disable GPG support
# saupdate_restart_spamd="YES"	# Restart sa-spamd when new rules are found


# If there is a global system configuration file, suck it in.
#
if [ -r /etc/defaults/periodic.conf ]
then
    . /etc/defaults/periodic.conf
    source_periodic_confs
