So the two possible approaches are: * traditional sdist: "setup.py build", "setup.py install" * Current wheel macros: "setup.py bdist_wheel", "pip install <wheel file>" If we tweak the %py_build_wheel macro to use `pip wheel` [1] rather than calling `setup.py bdist_wheel` directly, then even the wheel build macro would be usable without a setup.py shim (once pip itself fully supports PEP 517/518) Cheers, Nick.
