-  <description>
-    <p>
-   Aiming to be a good alternative to all other bittorrent clients out
-   there, qBittorrent is fast, stable and provides unicode support as well
-   as many other features. Additionally, qBittorrent runs and provides those
-   same features on all major platforms (Linux, Mac OS X, Windows, FreeBSD).
-  </p>
-    <p>
-   It is programmed in C++ / Qt and uses libtorrent (sometimes called
-   libtorrent-rasterbar) by Arvid Norberg. GeoLite data, created by MaxMind,
-   are included in qBittorrent. Its features include:
-  </p>
-    <ul>
-      <li>Polished µTorrent-like User Interface</li>
-      <li>Well-integrated and extensible Search Engine</li>
-      <li>All Bittorrent extensions (DHT, Peer Exchange, Full encryption, Magnet/BitComet URIs, ...)</li>
-      <li>Remote control through a Web user interface</li>
-      <li>Advanced control over trackers, peers and torrents</li>
-      <li>UPnP / NAT-PMP port forwarding support</li>
-      <li>Available in ~25 languages (Unicode support)</li>
-      <li>Torrent creation tool</li>
-      <li>Advanced RSS support with download filters (inc. regex)</li>
-      <li>Bandwidth scheduler</li>
-      <li>IP Filtering (eMule and PeerGuardian compatible)</li>
-      <li>IPv6 compliant</li>
