+ * ľAnytun
+ *
+ * ľAnytun is a tiny implementation of SATP. Unlike Anytun which is a full
+ * featured implementation ľAnytun 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.
