You need information on *every* package? Not just the ones you use? Technically
in your script, you can query pacman for the foreign packages, then compare to
an RPC response (and info can take multiple packages, just check the wiki),
then take action on those specific packages. I don't see the need to have
information on every single PKGBUILD on the AUR.
