# How could this plugin have been written in its simplest form?
# Something like this:
#
# ---------------------
# #!/bin/sh
#
# if [ "$1" = "config" ]; then
# echo "graph_title Load average"
# echo 'graph_args --base 1000 -l 0'
# echo 'graph_vlabel load'
# echo "load.label load"
# exit 0
# fi
# echo -n "load.value "
# cut -f1 -d' ' < /proc/loadavg
# ---------------------
#
# Except for the Nagios-warnings (which most people don't have any need
# for) and things used by installation scripts and munin-config (which
# you don't need if you don't plan on submitting your plugin to the
# pacakge), and the scaling (no milliload numbers) the two versions will
# work identically.
