I just released a project that I've been working on for a while, and mentioned during my JNUC API talk, that utilizes the JSS API to automatically merge changes that are made to git repositories. Effectively version controlling aspects of the JSS. I have included two git hooks, one to manage Extension Attribute objects and another to manage Script objects.
I hope the JAMFNation community finds this useful. It requires JSS 9.62 due to required API calls.
UPDATE:
Unfortunatley, I was asked to pull down this repository for internal reasons. And, shortly thereafter, I transitioned onto a different team and no longer work with the JAMF toolset. I had hoped that my old team would have been able to Open Source this in my absence, but it doesn't appear like they have been able to, and I'm not at liberty to do so at this time. My apologies to everyone still looking for this. I know there's a few copies floating around prior to me having to pull it down, and it was released under the BSD license which allows redistribution, with or without modification...
