Ah - that was part 2 which I am working on in my copious free time.

At the moment, xl info takes no parameters, or an -h or -n.

I was thinking it could be modifed to optionally take a positional
paramater, such as

xl info xen_version

Even with this however, my original point still stands.  Getting the
version number is awkward.
