title: devtools::document vs roxygen2::roxygenize
body: <p>Some time ago i've read somewhere that <code>devtools::document</code> is better than <code>roxygen2::roxygenize</code> for "complex packages/sitations" (this is what i remember), but unfortunately i can't find the link now and i didn't deepen at that time.</p>
  
  <p>Looking at respective help pages it's not clear to me how, so my question
  is: if sometime it's better to use <code>devtools::document</code> rather than
  <code>roxygen2::roxygenize</code>, when it's the case? for which kind of packages?</p>
  
  <p>Thanks, Luca</p>
