--   <li><i>Prometheus Haskell Client</i></li>
--   </ul>
--   
--   A simple and modern, type safe, idiomatic Haskell client for
--   <a>Prometheus</a> monitoring. Specifically there is no use of unsafe
--   IO or manual ByteString construction from lists of bytes.
--   Batteries-included web server.
