#!/bin/bash 

# This script implements a gerrit hook to handle changes being merged into projects
# which need to sync over to a github project.
#
# When the commit is merged to a branch which is listed as one we sync, we will sync up with
# the github branch using git fetch && git rebase -p then push it to github.
