Comment 3 for bug 434243

Thanks Bill; the syntax of the file looks ok. The hardest thing to decide is the score, which is why I didn't add the file straight-away: I'd like the score to be as low as possible for things to work as we expect.

I will try with a score of 995 which I think is the proper score to give PPA versions priority over other versions from the target release (even if higher). I fear a score of 1000 or above also forces installation of uninstalled packages.
