title: setup.py installing local packages
body: <p>If I have a tree that looks like:</p>
  
  <pre><code>├── project
  │   ├── package
  │   │   ├── __init__.py
  │   │   ├── setup.py
  ├── env
  └── setup.py
  </code></pre>
  
  <p>Is there a way to include the nested setup.py in the install for the top setup.py? I want to avoid this:</p>
  
  <pre><code>pip install -e . ; cd project/package ; pip install -e .
  </code></pre>
