	# Tools that can save round-trips to github and a lot of time:
	#
	# yamllint -f parsable pull_request.yml
	# pip3 install ruamel.yaml.cmd
	# yaml merge-expand pull_request.yml exp.yml &&
	# diff -w -u pull_request.yml exp.yml
	#
	# github.com also has a powerful web editor that can be used without
	# committing.
