Simple Git-based multi-server deployments

Ansible is used to manage most of Midwestern Mac's infrastructure and deployments, and while it's extremely easy to use, there are a couple situations where a project just needs a little code to be updated across two or more servers, from a central Git repository, or from one master application server.

All Git repositories include a hooks folder, which contains sample git hook scripts. Inside this folder are a series of sample hook files like post-commit.sample and pre-rebase.sample. If you add a shell script of the same name as any of these files (excluding the .sample) to this folder, Git will run the script when the particular action runs (e.g. git will run a post-commit script after a commit).
