title: How to write a git hook to restrict writing to branch?
body: <p>I'd like to restrict write access for the master branch to only several developers, while allowing others to pull everything and push to other non-master branches. Idea is that a developer would push to some other branch and then if code passes review, reviewer would merge it into the master branch.</p>
  
  <p>I'm pretty sure that this can be easily done with a git commit hook, but I don't know python and this seems like such a generic problem, that somebody must have written it already. Do you know where I could find such a script? Or if you have one lying around, please paste it here, for lazy people like me. </p>
