I'd like have a place where we can consult when we are working on a
random python package , something like an quick how to convert macros
or and a FAQ ,
for example with: " if your package still uses the `setup.py test`
command (deprecated for 5 years), please update to %pytest, %tox,
%{python3} -m unittest, etc. "
Thank you
