#
# Plugin to monitor the CPU temperature through lm-sensors.
# v1.0 (2008-02-15) Oliver Ladner <oli@lugh.ch>
# 
# Requirements:
# 	- A configured lm-sensors installation
#       - Supported device (see http://www.lm-sensors.org/wiki/Devices)
#       - grep, sed and awk
#
# Todo:
#       - Ability to monitor multiple sensors like fan speeds, voltage etc.
#       - Better checks (availabilty of lm-sensors, sensors itself, path names)
#
# Parameters supported:
#
# 	config
# 	autoconf
#
# Magic markers:
#%# capabilities=autoconf
