Git pre-commit hook

	#!/bin/sh

	# A JavaScript focussed git pre-commit hook
	#
	# It ensures that any files containing console.log() or alert() calls aren't able to be committed.
	# It also ensures that all JavaScript passes JSHint(which is assumed to be installed). A static code analysis tool which detects errors and potential issues from smelly JS - see http://www.jshint.com/ for more details
	#
	# Written by Damian Nicholson - @damian

	if git rev-parse --verify HEAD >/dev/null 2>&1
