+#!/bin/bash
+#
+# Plugin to measure CPU frequency via cpufreq-info binary.
+# This makes the plugin run on linux machines only.
+# However the same goes for using sysfs directly.
+#
+# Contributed by Jo Schulze
+#
+# Config variables:
+#
+#
+# Requires:
+# cpufrequtils	http://www.kernel.org/pub/linux/utils/kernel/cpufreq/cpufrequtils.html
+#
+# @remarks
+# jo20061130	using cpufreq-info should simplify the whole thing
+# jo20061202	tested on AMD K8 X2, intel Core 2 Duo
+#
+# $Log$

+# Magic markers - optional - used by installation scripts and
+# munin-config:
