installer VS pipsi

And probably https://github.com/pradyunsg/installer https://pypi.org/project/installer/ too, but that one isn't under the pypa org yet, given the author, it probably will be.

All that being said, the deprecations and removals are being done way before the replacements are in place and tested and features/rough edges rounded out, which I guess is python tradition at this point.

IMHO, the repos maintained by pypa should all be part of the core teams responsibility (e.g. pip is maintained by pypa, not core, but its installed as part of the python installer you download from the foundation's website...), along with solving building/installing/packaging/distributing as a whole. But the core team decided their volunteers didn't want to work on that (ok fair) and pypa stepped up to do it, but never really had enough manpower to tackle it well (ok also fair). And none of the tech companies ever thought "gee we rely so heavily on this awesome tool, maybe we should send them some money to keep the lights on..." So instead its just been a giant mess.

python -m installer --destdir="$pkgdir" once pradyunsg/installer#66 is finally merged

Pipsi is no longer maintained fwiw: https://github.com/mitsuhiko/pipsi
