FYI, setuptools uses and supports #! lines on Windows, with the 
executable path in quotes if it contains spaces.  For a given script 
"foo", it generates two files:

     foo.exe
     foo-script.py

And the .exe is just a standardized .exe file that looks in an 
adjacent -script.py file of the same name for the #! line.

(This is of course only for scripts generated using 
setuptools-specific features.)

Setuptools works with versions 2.3 through 2.5, but of course that's 
because of the .exe wrappers.
