The auto-merge workflow automatically approves dependabot PRs that
update dependencies or github actions where the semver difference is
at most a minor upgrade. These PRs are then auto-merged once the CI
checks have passed.
The labeller workflow adds / removes the auto-merge label to make
auto-merging more visible in issue lists and to make it possible to
filter such PRs. This workflow is unfortunately not triggered
when the auto-approve workflow enables auto-merging due to GH anti-
recursion rules, so the auto-merge workflow adds the label explicitly.
Tox manages test environments for all supported Python versions, as
well as linting and formatting tools. On GitHub, the test and lint
steps are kept as close as possible to the Makefile equivalents.
