# Workflow to build and test wheels.
# To work on the wheel building infrastructure on a fork, comment out:
#
# if: github.repository == 'numpy/numpy'
#
# in the get_commit_message job. Be sure to include [wheel build] in your commit
# message to trigger the build. All files related to wheel building are located
# at tools/wheels/
# Alternatively, you can add labels to the pull request in order to trigger wheel
# builds.
# The labels that trigger builds are:
# 36 - Build(for changes to the building process,
# 14 - Release(ensure wheels build before release)
