Awesome. But, I tried running the 'hg update xen-3.2.0' within the 
xen-3.2-testing.hg repository directory and it gave me this msg:
"abort: unknown revision xen-3.2.0".

The other command did not work too as it asked for the name of files that need 
to be patched.

Is "hg update" command correct? or I have to specify some other revision 
number. Please let me know.

I really appreciate you help.
