pre-commit hook

#!/bin/sh

# Git pre-commit hook that prevents accidentally committing things that shouldn't be, like:
#
#   * ":focus", used with RSpec/Guard
#   * "show_page", used to debug request specs
#   * "console.log" or "console.debug", used in JavaScript debugging
#   * "DO NOT COMMIT!" comments
#
# Modify the regexps to suit your needs. The error message shows the full regexp match,
# or just the first capture group, if there is one.
#
# To bypass this commit hook (and others), perhaps when defining ":focus" or "show_page"
# for the first time, commit with the "--no-verify" option.

# Install:

# * ln -s /path/to/pre-commit.sh /path/to/project/.git/hooks/pre-commit

Code doesn't actually check for "DO NOT COMMIT"
