I would not call that a script, it's more a journal of 
what i did. As xen comes with a script symlinking from 
the kernel tree to the xen tree, i first produce a
classical xen-only patch. The last diff makes an all-
in-one (xen & skas!) patch against the vanilla 2.6.10.

But as i said: it doesn't work (yet).
