Luajit is a dynamic scripting language completely compatible to lua 5.1. the whole VM has been rewritten from the ground up
and is relentlessly optimized for performance. It combines a high-speed interpreter, written in assembler, with a state-of-the-art JIT compiler.
A substantial reduction of the overhead associated with dynamic languages allows it to break into the performance range traditionally reserved for offline,
static language compilers.

There was additional code needed to enable neutrino to compile against lua 5.1. This was mostly taken from the luaposix compat-headers.
There are still some minor issue that will be easy to fix but it's up and running so damn fast!
