@lurch These changes look sane to me but I am not a Python expert, any comments from you?

Sorry, I hadn't seen this before, oops. The changes to pico_project.py look good (although you'll obviously need to rebase onto the latest changes), but I'm afraid I've never written a setup.py script. Don't most projects that use pip use it to install stuff from PyPI? Is it absolutely necessary to move the repo-files into a subdirectory?

Yes, making the package available on PyPi is also possible. Ref: https://packaging.python.org/tutorials/packaging-projects/. Structure is similar to the one I'm making.

I would have preferred to have kept the files in the root directory. It seems that having a subdirectory with the Python package (application in our case) name is "standard". Refs:
https://docs.python-guide.org/writing/structure/

Fair enough, always good to adhere to standards 🙂

Have rebased as requested and put pip installation as "optional" and at the foot of the README.
