i'm not sure there is a standard way to do so with distutils.
My current way to handle executable scripts is to have a run() function in
the myexecutable.py module, and then to have a very simple myexecutable
script with the following content:

#!/usr/bin/python
from mypackage import myexecutable
myexecutable.run()

And then register this script using distutils'"scripts" keyword argument.
This has the advantage that I can also create a very simple .bat file for
windows users without code duplication.
