Review comment:
One more thing. I think it will be better if you remove the whole
chapter about "replacing python with python3" - but instead you should simply
**actually replace** it as part of this PR.
I believe while "python" might not be available on the PATH, if python3 is
available, using `python3` there is the **right** thing to do .
