# This file needs to be copied into <repoRoot>/.git/hooks, and named "pre-commit".
# Other examples and details of the pre-commit hook can be found in the "pre-commit.sample" file, in that folder.
#
# Essentially what this script does is look at each file that has been staged, and then
# check those files for any sign that they have been prettified, and not then re-uglified.
# 
# This script will be run any time the user attempts to commit.
# If it returns non-zero, the commit will be prevented.
