title: Doxygen for Python: How to generate documentation for nested functions
body: <p>I am documenting my Python code using Doxygen. The code makes use of Pythons capability of defining nested functions.</p>
  
  <p>So I have documented them as if they were "normal" functions and set <code>EXTRACT_ALL=YES</code>.</p>
  
  <p>But still, the nested functions cannot be found anywhere. Is there a way to make Doxygen do that?</p>
  
  <p>(Doxygen version 1.8.6)</p>
