#
#     ./scripts/install-git-hooks.sh
#
# After this, every `git commit` runs the test suite first and aborts if it
# fails, then refreshes the generated devlog (client/js/devlog_data.js) and
# stages it. Skip once with `git commit --no-verify`.
#
# Uninstall with:
#     git config --unset core.hooksPath
