define Package/gnunet/description
 GNUnet is a peer-to-peer framework focusing on security. The first and
 primary application for GNUnet is anonymous file-sharing.  GNUnet is
 currently developed by a worldwide group of independent free software
 developers.  GNUnet is a GNU package (http://www.gnu.org/).

 This is an ALPHA release.  There are known and significant bugs as
 well as many missing features in this release.

 This package provides the core components of GNUnet including the
 CADET routing engine, a DHT implementation and most transports as well
 as their helpers.
