title: Can Doxygen easily be configured to recognise TODO and FIXME lines?
body: <p>I've just installed and setup an instance of Doxygen, but out of the box it only finds TODO tags in code when marked in a block like:</p>
  
  <pre><code>/**
   * @todo Foo
   */
  </code></pre>
  
  <p>It doesn't seem to find:</p>
  
  <pre><code>// TODO Foo
  // FIXME Bar
  // @todo Baz
  </code></pre>
  
  <p>Most IDE's and bug trackers which handle parsing are fine with them, is there an easy way to configure Doxygen to find them and list them as ToDo items?</p>
