A git hook to stop commits with binding pry... for now. Easy to add more expressions.

pre-commit.rb

#!/usr/bin/env ruby

##
# This file must be renamed to pre-commit without extension and
# added to your .git/hooks directory
# After that, run `chmod 755 pre-commit` to make it executable

$user = ENV['USER']
