# 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.
