	# If another push to the same PR or branch happens while this workflow is still running,
	# cancel the earlier run in favor of the next run.

	# There's no point in testing an outdated version of the code. GitHub only allows
	# a limited number of job runners to be active at the same time, so it's better to cancel
	# pointless jobs early so that more useful jobs can run sooner.
