# Script informed by the collectd monitoring script for smartmontools (using smartctl)
# by Samuel B. <samuel_._behan_(at)_dob_._sk> (c) 2012
# source at: http://devel.dob.sk/collectd-scripts/
# TODO: This probably needs to be a little more complex. The raw numbers can have more
# data in them than you'd think.
# http://arstechnica.com/civis/viewtopic.php?p=22062211
# Formatting done via shfmt -i 2
# https://github.com/mvdan/sh
# Ensure predictable numeric / date formats, etc.
