Till Maas constructed a truly useful Fedora Easy Karma script in Python. There’s a wiki page about it already, and it’s very easy to use. I just used it to test and give karma to a handful of packages in the pre-release Fedora 13 updates-testing repository in just a few minutes. It’s a great enabler for our community. You do need to have the latest fedora-packager package installed (currently in updates-testing) to use it.
Nice work, Till!
