title: Developing Python Module
body: <p>I'd like to start developing an existing Python module. It has a source folder and the setup.py script to build and install it. The build script just copies the source files since they're all python scripts.</p>
  
  <p>Currently, I have put the source folder under version control and whenever I make a change I re-build and re-install. This seems a little slow, and it doesn't settle well with me to "commit" my changes to my python install each time I make a modification. How can I cause my import statement to redirect to my development directory?</p>
