prepare-commit-msg

#!/bin/sh
#
# An example hook script to verify what is about to be committed.
# Called by "git commit" with no arguments.  The hook should
# exit with non-zero status after issuing an appropriate 
# message if it wants to stop the commit.
#
# For branches that follow the following naming it [anything]/[project]/[anything]
# or [project]/[anything] it will prepend the project to the commit msg.
#
# Inspired by https://gist.github.com/bartoszmajsak/1396344/97081e76ab275f5fe526347908503febd1340495
