I don't mean to be nosy (and I'm making some assumptions about the
particular tool at issue here), but I just saw this one fly past my
inbox and thought some feedback might be helpful.

Making every python file in the distribution is probably not what you
want - most python files aren't supposed to be executed directly.

Setuptools has an entry_points option where you can dynamically create
a script to launch your application[1]. For example, you could have:

entry_points=[
    "console_scripts": [
        "vend-server=VendServer.VendingMachine:main"
    ]
]

That would run the main() function on execution of the "vend-server"
command after installation.

Hope that's useful :)

Sam.
