So that means that *today*, Bento can consume Distutils2 project and 
compiles them, just by reading their setup.cfg, right ?

And the code you have to convert setup.cfg into bento.info is what I was 
talking about.

It means that I can create a project without a setup.py file, and just 
setup.cfg, and have it working with distutils2 *or* bento

That's *exactly* what I was talking about. the setup.cfg is the *common* 
standard, and is planned to be published at PyPI statically.

Let people out there use their tool of their choice to install a project 
defined by a setup.cfg

so 2 questions:

1/ does Bento install things following PEP 376 ?

2/ how does the setup.cfg hooks work wrt Bento ?

and last one proposal: how a PEP that defines a setup.cfg standard that 
is Bento-friendly, but still distutils2-friendly would sound ?
