+#  Create a generic HPC image 
+#  This script is an example of how to create an HPC image with xCAT stateless.
+#  in this example you may need to change some of the parameters.  In the future
+#  we should probably place this in the database...
+#  All good sys admins can reproduce their environments.  Creating a stateless 
+#  image should be reproducable.  Doing this with a script is a good idea.
