pre-commit

#!/usr/bin/env ruby 

# This pre-commit hook will prevent any commits to forbidden branches 
# It will also help prevent you leaving debuggers and merge conflig flags 
# Put this file in your local repo, in the .git/hooks folder 
# and make sure it is executable by running: chmod u+x pre-commit 
# The name of the file *must* be "pre-commit" for Git to pick it up.
