+# This script allows you to start multiple cache bench instances across a cluster
+#
+# Note that this requires BASH, as well as that all your instances have the cache
+# bench framework installed in the same location.  Finally, it requires SSH keys
+# set up such that executing commands using 
+#
+#     $ ssh hostName "command" 
+# 
+# will work without prompting for passwords, or any user input.
