title: Clojure docstring for libraries/namespaces
body: <p>How to add docstrings and/or comments to Clojure libaries/namespaces as a whole, i.e. not just to specific functions within the namespace?</p>
  
  <p>I've noticed that the clojure source uses <code>(comment ...)</code> in some places to do this (<a href="https://github.com/clojure/clojure/blob/master/src/clj/clojure/parallel.clj" rel="noreferrer">example</a>), is that recommended?</p>
