# Protect against using git push by mistake without getting a code review through gerrit first
# install by adding the following to your .bashrc (or .zshrc) (after changing the path for the location of the script):
#   alias git="$HOME/git-override.pl"
# this also relies on having a git alias for pushing to gerrit in place called "push-refs". Create that by adding the
# following to the [alias] section of your ~/.gitconfig:
#  push-refs = push origin HEAD:refs/for/master
