title: Embed a plantuml diagram somewhere in a docstring (with the Sphinx plantuml extension)
body: <p>I installed the sphinxcontrib-plantuml extension which works fine if I run the HTML builder e.g. with following testmodule.rst file for a corresponding testmodule.py file:</p>
  <pre><code>testmodule module
  =================
  
  .. automodule:: testmodule
      :members:
      :undoc-members:
      :show-inheritance:
  
  .. uml::
     
     Alice -&gt; Bob: Hi!
     Alice &lt;- Bob: How are you?
  </code></pre>
  <p>This adds the UML diagram at the very end of the document. Unfortunately I didn't find out how to embed a UML diagram anywhere in the documentation e.g. somewhere in the middle of a methods docstring block.</p>
  <p>Does anyone know how to do that?</p>
