title: Arbitrary sections in roxygen docs
body: <p>The way <a href="http://roxygen.org/">Roxygen</a> seems to work is that the first line is the <code>\title</code>, everything else is in the <code>\details</code>, and then any <code>@foo</code> directives handle those things. But R documentation is richer than that. I can have <code>"\section{Llamas}{Are they ungulates?}"</code> in .Rd files.</p>
  
  <p>But I can't get Roxygen to do anything other than wrap it all in \details. Am I missing something?</p>
  
  <p>I have a hacky solution, which is to stick an unmatched <code>}</code> before my <code>\section</code>. This then ends the <code>\details</code> section. I then have to not put an ending <code>}</code> in, because roxygen sticks one in thinking its closing the <code>\details</code>. Eeeeeurrrrrrrrgh.</p>
