SUMMARY="Anonymizing Internet communication system"
DESCRIPTION="
Tor helps you defend against traffic analysis, a form of network surveillance
that threatens personal freedom and privacy, confidential business activities
and relationships, and state security. 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.
