Tor's users employ this network by connecting through a series of virtual tunnels rather than making a direct connection, thus allowing both organizations and individuals to share information over public networks without compromising their privacy. Along the same line, Tor is an effective censorship circumvention tool, allowing its users to reach otherwise blocked destinations or content. Tor can also be used as a building block for software developers to create new communication tools with built-in privacy features. This package contains the Tor software that can act as either a server on the Tor network, or as a client to connect to the Tor network. --------------------------------------------------------------------------------Update Information: update to upstream release 0.3.1.9.
