Pushing new Sparkle releases of our internal apps is a pain. I have to make the build, make the release notes file, sign the .zip with the private key, and add a new entry to the appcast file tying everything together.

I'd love it if Jenkins could help: use the commit messages for the release notes, and automatically do the rest of it.

Should I be looking at writing a new Jenkins plugin, or using shell scripting, or is there something already that will do what I want? (A quick Google didn't find anything.)

I'm new to Jenkins, and am still trying to get a feel for what it can do. Do any other maintainers of Cocoa apps have any tips?
