Exim log rotation

[Bill Moseley <moseley@hank.org>]

I'd like to rotate my exim logs weekly instead of daily.

In /etc/cron.daily/exim there's:

# Cycle logs
if [ -x /usr/bin/savelog ]; then
  for i in mainlog rejectlog paniclog; do
    if [ -s /var/log/exim/$i ]; then
      savelog -p -c 10 /var/log/exim/$i >/dev/null
    fi
  done
fi

I could move that bit of code into a new script in cron.weekly, but I'm
wondering if there's a better way -- I'm worried that updating exim
package in the future will then update that cron.daily script and then
I'll have two rotation schemes going.

Is there a reason why logrotate isn't used for exim?  savelog doesn't 
seem to have much for features.
