<title>Menu Tree</title>

<!--
  Tree diagrams are comparable to HTML lists;
  this CSS overrides HTML list markup to draw trees.
  Tree diagrams have no real trunks,
  only leaves (<p>), stems(<li>) and branches (<ul>).
  Horizontal trees have chilren right of parents,
  so vertical branches and horizontal stems.
  CSS dislikes comments nested in comments...
