create script wrappers on Windows by symlinking to the py3.3 launchers

The wheel installer in Python 3.3 could produce script wrappers by symlinking the launcher .exe. Works on NTFS on Vista+.

(The wheel specification needs a "recommended installer features" section to document #! shebang fixing and things like this, and to document that the scripts folder receives special treatment.)

But symlinking still requires administrator access even on those systems, does it not?

[pfmoore]

Correct

[agronholm]

So are we going to do this or not? I figured that there's a reason why setuptools/pip do not do this.

[pfmoore]

If you want my opinion, no we shouldn't. I'm not 100% sure what @dholth meant by "the wheel installer" - normally wheels get installed by pip, which has it's own approach to script wrappers. If we're talking about the wheel install command, I favour keeping that simple, and in particular avoiding getting into platform-specific complexities.

[agronholm]

This here maybe? https://github.com/pypa/wheel/blob/master/wheel/tool/__init__.py#L147

[pfmoore]

Yeah, that's the wheel install command. Like you say, pip/setuptools don't do this, so wheel install shouldn't, either.

[agronholm]

Ok, then it's settled.
