So distutils.core.setup(script_name=file, script_args=commands) is the
same as distutils.core.run_setup(file, commands)?

If so, is there any need for a run_setup function?

I don't care about the exact spelling, I just want access to the
Distribution object from Python. However... to me run_setup seems
different enough from setup to be a different function. Also
stop_after=init seems fairly close to a command to me. But I promise to
stop quibbling ;-) Whatever you decide is great.
