-name: Publish Python 🐍 distribution 📦 to PyPI or TestPyPI
-
-# https://github.com/pypa/gh-action-pypi-publish strongly recommends a
-# separate publishing job when building platform-specific distribution
-# packages, hence this.
-#
-# This should not be run until the release artifacts have been deployed.
-# The only way I can see to trigger this automatically is to have all
-# platform builds in a single workflow file and use on: `workflow_run`
-# so this is triggered when that workflow completes. Once all platform
-# builds are moved to GitHub Actions we can try making each platform
-# workflow reusable and making another workflow that calls each of
-# them via `uses` and use `on: workflow_run` here.
-#
-# We also have to figure out how to determine if the workflow deployed
-# to releases. Maybe can use the GitHub REST API to get an artifact
-# from the triggering workflow that is set only when deploying
-# releases. See https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#using-data-from-the-triggering-workflow.
-# Alternatively maybe there is some way of querying what triggered
-# the workflow that we can test in an `if:` in the job as noted below.
