#  �Anytun
#
#  �Anytun is a tiny implementation of SATP. Unlike Anytun which is a full
#  featured implementation �Anytun 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.
