+# This script deploys a cluster
+# -------------------------------------------
+#
+# Pre-requisites
+# - Python 2.7
+# - SSHLibrary (pip install robotframework-sshlibrary)
+# - pystache (pip install pystache)
+# - argparse (pip install argparse)
+#
+# The input that this script will take is as follows,
+#
+# - A comma separated list of ip addresses/hostnames for each host on which the distribution needs to be deployed
+# - The replication factor to be used
+# - The ssh username/password of the remote host(s). Note that this should be the same for each host
+# - The name of the template to be used.
+# Note that this template name should match the name of a template folder in the templates directory.
+# The templates directory can be found in the same directory as this script.
+#
+# Here are the things it will do,
+#
+# - Copy over a distribution of opendaylight to the remote host
+# - Create a timestamped directory on the remote host
+# - Unzip the distribution to the timestamped directory
+# - Copy over the template substituted configuration files to the appropriate location on the remote host
+# - Create a symlink to the timestamped directory
+# - Start karaf
