Quick script to update Monit wih the binary release, since Debian's packages lag so far behind.

update_monit.sh

#!/bin/sh
# Script for Debian, which lags majorly behind on Monit releases.
# This will download the given version and overwrite Debian's binary and man-page,
# install a symlink to monitrc (Debian's package expects it in /etc/monit/monitrc,
# while the distributed binary expects /etc/monitrc), and installs the distributed
# example configuration at /etc/monit/monitrc.pkgdist
