    <h1>Known Issues</h1>
    <ul>
      <li>Perl formatting is really crappy.   Partly because the author is lazy and
      partly because Perl is
      <a href="http://www.perlmonks.org/?node_id=663393">hard</a> to parse. 
      <li>On some browsers, <code>&lt;code&gt;</code> elements with newlines in the text
      which use CSS to specify <code>white-space:pre</code> will have the newlines
      improperly stripped if the element is not attached to the document at the time
      the stripping is done.   Also, on IE 6, all newlines will be stripped from
      <code>&lt;code&gt;</code> elements because of the way IE6 produces
      <code>innerHTML</code>.   Workaround: use <code>&lt;pre&gt;</code> for code with
      newlines. 
    </ul>
