#
# Plugin to monitor the CPU temperature through lm-sensors
# on multicore AMD cpus 
#
# Author: Marc Schiffbauer <marc@schiffbauer.net>
#
# Requirements:
# 	- A configured lm-sensors installation with k8temp kernel module
#	- rewuired shell commands: sensors, grep, sed, uniq, cut
#
# Parameters supported:
#
# 	config
# 	autoconf
#
# Magic markers:
#%# capabilities=autoconf

# VERSION 1.0
