A minimalist git deployment tool with bash script and cron on linux. It works for machine behind firewall and it has minimal dependancies. It will ensure the repo is update-to-date with master branch and it can call a script before and after an update.

This can be convenient for staging environment. (flock prevent concurrent tasks.)
