Whatever people want! At least, that=E2=80=99s my hope. Ideally we get =
away from
the idea that any particular build system is the right build system =
(because
the needs of a pure python thing like six.py is vastly different from =
Numpy
which needs Fortran and other crazy things).

My end goal is, as long as your build system can consume a sdist (or =
maybe
a repository too, still up in the air, but some kind of source input) =
and
produce a wheel (whether this is actually a zipped up wheel file or a =
properly
formatted directory is also still up in the air). Then you have a good =
enough
build system and that is all it needs to do, it doesn=E2=80=99t need to =
also implement
installing and what not, that=E2=80=99s some other tool=E2=80=99s job.

Either twine, or we=E2=80=99ll fold that functionality into pip.

Whatever tool you want! We=E2=80=99ll have defined formats so as long as =
your tool
speaks those formats it can install them. In the case of already =
=E2=80=9Ccompiled=E2=80=9D
(pure Python or not) binary .whl files it can just download them, unzip,
move into the correct location + install deps and such. For source files
(in a not-yet thought out or done sdist 2.0 thing) it can download the
sdist 2.0 file, install the build dependencies, invoke the build tool =
for
this package (from above), get the wheel it produced, and then install
that as if it had downloaded it from PyPI.

Same answer here.
