      Transmission is a BitTorrent client which features a simple interface
      on top of a cross-platform back-end.
      Feature spotlight:
        * Uses fewer resources than other clients
        * Native Mac, GTK+ and Qt GUI clients
        * Daemon ideal for servers, embedded systems, and headless use
        * All these can be remote controlled by Web and Terminal clients
        * Bluetack (PeerGuardian) blocklists with automatic updates
        * Full encryption, DHT, and PEX support
