-# SSH authentication script for cluster edition
-# This script will create a single key pair, which is then
-# propagated throughout the entire cluster.
-# There are two options for setup; temporary setup
-# persistent setup. If no options are specified, and the script
-# is only given ip addresses or host names, it will default to
-# the temporary setup. An ssh directory is then created in
-# /tmp/mn/ssh on each node, and mounted with the keys over the
-# user's ssh directory. This setup can easily be torn down by running
-# clustersetup with the -c option.
-# If the -p option is used, the setup will be persistent. In this
-# case, the key pair will be be distributed directly to each node's
-# ssh directory, but will be called cluster_key. An option to
-# specify this key for use will be added to the config file in each
-# user's ssh directory.
