[Scons-users] Problem installing scons via pip

[Eric Fahlgren]

Just to confirm: the current src/setup.py is used /only/ for
packaging/product installation?  (So, if I totally replace it to build a
wheel and do nothing else, that would be ok?)

I am very far from being an expert on packaging, but I just created
whl-building setup files for a couple of packages in the past month, so
it's fresh in my mind and thus it's possible that I could actually do
something here before I forget everything I learned.
