[pacman-dev] Yum-presto like

[Ray Rashif]

Sorry for hijacking this a little.

Is there documentation available on this? I'd like to exploit this feature
with a personal repo (3 computers with slow connections use it); what should
be done on the packaging/server side so that if the user enables UseDelta,
it will work seamlessly with packages built with xdelta? That's as far as I
understand this. There were discussions in the past but I never noticed how
one would go about setting it up.
