-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.
