Description: Just in time compiler for Lua programming language version 5.1
LuaJIT implements the full set of language features defined by Lua 5.1. The

and can be deployed as a drop-in replacement.
.
This package contains the standalone interpreter/jitter that can be used
as a replacement for the standard lua5.1 interpreter.
