      longDescription = ''
        GNUnet is a framework for secure peer-to-peer networking that
        does not use any centralized or otherwise trusted services.  A
        first service implemented on top of the networking layer
        allows anonymous censorship-resistant file-sharing.  Anonymity
        is provided by making messages originating from a peer
        indistinguishable from messages that the peer is routing.  All
        peers act as routers and use link-encrypted connections with
        stable bandwidth utilization to communicate with each other.
        GNUnet uses a simple, excess-based economic model to allocate
        resources.  Peers in GNUnet monitor each others behavior with
        respect to resource usage; peers that contribute to the
        network are rewarded with better service.
