+# Action builds a universal (Win32/Win64/macOS-universal/Linux-x64) Python wheel
+# from the source code, using Hatchling, and uploads it as an artifact. This wheel
+# can then be distributed with new releases. The action is triggered by pushes into `main`
+# or pull_requests into `main` or `dev` (for testing). To aid in releases, the workflow is
+# also triggered when new SemVer tags are created. This action handles downloading all
+# shared library files and including them in the resulting wheel.
