Although setuptools is capable of that kind of scenario, sometimes it's not worth the overhead. A good rule of thumb is that if you have defined access points for others to consume your code with (command line tools, Python modules, or Setuptools entry points), it's a good idea to make a Python package like this. Otherwise, skip it.
