SUMMARY="Peer-to-peer VPN, NCD scripting language, tun2socks proxifier"
DESCRIPTION="
    BadVPN is an open-source peer-to-peer VPN system. It provides a
    Layer 2 (Ethernet) network between the peers (VPN nodes). The peers
    connect to a central server which acts as a chat server for them to
    establish direct connections between each other (data connections).
    These connections are used for transferring network data (Ethernet
    frames), and can be secured with a multitude of mechanisms.

    The BadVPN package also includes other network-related software,
    like tun2socks and NCD.
