+     Tor protects you by bouncing your communications around a distributed 
+     network of relays run by volunteers all around the world: it prevents 
+     somebody watching your Internet connection from learning what sites you 
+     visit, and it prevents the sites you visit from learning your physical 
+     location. Tor works with many of your existing applications, including 
+     web browsers, instant messaging clients, remote login, and other 
+     applications based on the TCP protocol.
