+00004  *  The secure anycast tunneling protocol (satp) defines a protocol used
+00005  *  for communication between any combination of unicast and anycast
+00006  *  tunnel endpoints.  It has less protocol overhead than IPSec in Tunnel
+00007  *  mode and allows tunneling of every ETHER TYPE protocol (e.g.
+00008  *  ethernet, ip, arp ...). satp directly includes cryptography and
+00009  *  message authentication based on the methodes used by SRTP.  It is
+00010  *  intended to deliver a generic, scaleable and secure solution for
+00011  *  tunneling and relaying of packets of any protocol.
