title: Sphinx autodoc is not automatic enough
body: <p>I'm trying to use Sphinx to document a 5,000+ line project in Python. It has about 7 base modules. As far as I know, In order to use autodoc I need to write code like this for each file in my project:</p>
  
  <pre><code>.. automodule:: mods.set.tests
      :members:
      :show-inheritance:
  </code></pre>
  
  <p>This is way too tedious because I have many files. It would be much easier if I could just specify that I wanted the 'mods' package to be documented. Sphinx could then recursively go through the package and make a page for each submodule.</p>
  
  <p>Is there a feature like this? If not I could write a script to make all the .rst files, but that would take up a lot of time.</p>
