  <h3>What does this do?</h3>
  <p>Displays the metadata for this page. Both global metdata from the global settings page and metadata for each page will be shown.</p>
  <h3>How do I use it?</h3>
  <p>Just insert the tag into your template like: <code>{metadata}</code></p>
  <h3>What parameters does it take?</h3>
  <ul>
    <li><em>(optional)</em>showbase (true/false) - If set to false, the base tag will not be sent to the browser.  Defaults to true.</li>
    <li><em>(optional)</em>assign - Assign the output to a smarty variable named in assign instead of outputting it directly.</li>
  </ul>
