# README
# ======
#
# All the jobs are defined with `matrix` for OS and Python version, even if we
# only run them on one combination of OS/Python. The reason for this is you get
# a nice side-effect that the OS and Python version of the job are listed in
# parentheses next to the job name in the Actions UI.

# This prevents workflows from being run twice on PRs
