I believe Daniel already covered it in PEP 427 - rather than baking
the entry point wrappers into the wheel, installers can generate any
needed entry point wrappers if the wheel includes Python scripts in
{distribution}-{version}.data/scripts/ (see
http://www.python.org/dev/peps/pep-0427/#recommended-installer-features)

Now, there may be holes in that scheme, but it seemed solid enough
when I approved the PEP.

The big problem is that implementations don't do that :-( AFAIK, none of distlib, pip or wheel itself do anything with script wrappers except rewrite #! lines (which is the other, much easier, item in that section).

At the moment, bdist_wheel just puts the exe wrappers generated from the source into the wheel itself, which again is probably wrong in the context what the PEP suggests.

As I said in my other email, I think this is subtle enough that we need a stdlib implementation to stop people making mistakes like this. It's certainly not fair to expect a mostly-Unix development team to get this sort of Windows arcana right without some help.
