# 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
