/*
* 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.
