	# since the linting output should be machine dependent and not vary much if
	# at all by Python minor version.

	jobs:
	# Lint against selected pre-commit hooks (see https://pre-commit.com
	# and https://github.com/pre-commit/action).
	# The config. applied here is from our .pre-commit-config.yaml
	#
	# Note the pre-commit linting includes all of the other linters configured
	# to run as pre-commit hooks, namely black, flake8 and docformatter etc.,
	# so there is no need to set these up individually!
