+=head1 DESCRIPTION
+
+  xen-create-nfs is a simple script which allows you to easily create
+ a single configuration file for a Xen guest which will mount its remote
+ filesystem over an NFS root.
+
+  It doesn't create any images to use for local storage, and it doesn't
+ support more than the minimal number of options to completement the
+ existing xen-create-image script, however it is hopefully useful.
