(description
- "GNUnet is a framework for secure peer-to-peer networking that does not
-use any centralized or otherwise trusted services. Our high-level goal is to
-provide a strong free software foundation for a global network that provides
-security and privacy. GNUnet started with an idea for anonymous
-censorship-resistant file-sharing, but has grown to incorporate other
-applications as well as many generic building blocks for secure networking
-applications. In particular, GNUnet now includes the GNU Name System, a
-privacy-preserving, decentralized public key infrastructure.")
