title: Python setup, install one module as a sub module of another module?
body: <p>I would like to create a package that installs into a submodule of another python package as an extension.</p>
  
  <p>Basically the original module is set up like so:</p>
  
  <pre><code>origmodule/
      __init__.py
      stuff.py
      ext/
          __init__.py
          # This module is empty
  </code></pre>
  
  <p>And then have my extension module installed into the empty origmodule.ext module. Reading the instructions for <code>distutils</code> it was not clear if this is possible or supported. The end goal is so that my extension module once installed would be imported like this: </p>
  
  <p><code>import origmodule.ext.my_extension</code> </p>
