no setup.py in unzipped Distutils

[Donnal Walter]

The package I wish to distribute has the following structure:

Mindwrapper (directory)
   __init__.py
   api.py
   setup.py
   README.txt
   abstraction (directory)
     __init__.py
     (8 modules)
   presentation (directory)
     __init__.py
     (10 modules)
   samples (directory)
     __init__.py
     pkinetics (directory)
       __init__.py
       (5 modules)

My setup.py script looks like this:

from distutils.core import setup

setup(name="Mindwrapper",
       version="0.1.01",
       description="Custom clinical application development framework",
       author="Donnal Walter",
       author_email="donnal at donnal.net",
       licence="BSD",
       url="http://mindwrapper.org",
       package_dir={'Mindwrapper': '.'},
       packages=['Mindwrapper',
                 'Mindwrapper.abstraction',
                 'Mindwrapper.presentation',
                 'Mindwrapper.samples',
                 'Mindwrapper.samples.pkinetics'])

This appears to work fine *except* that when I unzip the resulting 
archive file, there is no setup.py script file, so how does the end user 
run "python setup.py install" from the Mindwrapper-0.1.01 directory? Thanks.
