build-publish.yml

# This workflow is used to build all the wheels and source distributions for
# the project and, on tags and releases, upload them. It is enabled on every
# commit to ensure that the wheels can be built on all platforms, but releases
# are only triggered in two situations:
#
# 1. When a tag is created, the workflow will upload the package to
#    test.pypi.org.
# 2. When a release is made, the workflow will upload the package to pypi.org.
#
# It is done this way until PyPI has draft reviews, to allow for a two-stage
# upload with a chance for manual intervention before the final publication.
