# ClusterInfo AWStats plugin
# This plugin allow you to add information on cluster chart from
# a text file. Like full cluster hostname.
# You must create a file called clusterinfo.configvalue.txt which contains 2
# columns separated by a tab char, and store it in the DirData directory.
# The first column is the cluster number and the second column is the text
# you want to add.
