- *  uAnytun
- *
- *  uAnytun is a tiny implementation of SATP. Unlike Anytun which is a full
- *  featured implementation uAnytun has no support for multiple connections
- *  or synchronisation. It is a small single threaded implementation intended
- *  to act as a client on small platforms.
- *  The secure anycast tunneling protocol (satp) defines a protocol used
- *  for communication between any combination of unicast and anycast
- *  tunnel endpoints.  It has less protocol overhead than IPSec in Tunnel
- *  mode and allows tunneling of every ETHER TYPE protocol (e.g.
- *  ethernet, ip, arp ...). satp directly includes cryptography and
- *  message authentication based on the methodes used by SRTP.  It is
- *  intended to deliver a generic, scaleable and secure solution for
- *  tunneling and relaying of packets of any protocol.
