[Cooker] Best way to update after mirror

[B. K. Barley]

Hey all,

        I read over the recent faq, and checked stuff out on the mandrake site but
I'm still confused as to the best way to update new rpms downloaded after
mirroring.
        I tried looking at autoirpm but that seems to be an install on demand type
utility.  What I'm looking for is something that will scan an installation,
compare installed rpms with the local copy of the mirror and update
installed rpms (plus changed dependent stuff) automatically.
        Any suggestions, information/instructions?
