+ * anylike
+ *
+ * anylike is an IKEv2 Implementation written in Lua and C. It's main
+ * design goal is to provide anytun and uanytun or any other SATP
+ * implementation with a key exchange mechanism but it should also be
+ * possible to use anylike as key exchange daemon for IPSec security
+ * associations. The use of Lua guarantees that anylike is easily
+ * portable to many platforms including very small ones like wireless
+ * routers.
