title: TYPO3: metatags set by editor
body: <p>Recently I saw a nice extension of Typo3. It is called metatags but I can't find it in the repository. Can someone tell me the extension key?</p>
  
  <p>With that extension it is possible to set keywords, description, robots, revisit, expires, cache-control, pragma and so on. Is it an old extension or a custom one?</p>
