-        * 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
