💪 Motivation

…so that familiarity with existing projects can boost productivity developing and debugging PDS Python apps.

📖 Additional Details

See the Python Packaging Authority's guide to Building and Publishing Python packages for the latest.

Some notable differences:

• No more setup.py or setup.cfg — everything's in pyproject.toml now
• MANIFEST.in is no longer required
• hatch is now a supported build system
• Namespaces are greatly simplified compared to what we have now

While we're at it, it might be nice to fix the Roundup Action so that it properly puts Python projects into their own virtual environments and allow Python projects to use Sphinx tools newer than version 3.2.1.
