+ *  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.
