Am I understanding LuaJIT correctly?

[Phlox <phloxicon@...>]

I have a C++ game that runs Lua scripts but then I heard about LuaJIT running scripts faster so I tried setting it up. First off, am I right in saying that I can use it for a big project like this? I read on the website that "It can be used to run simple Lua statements or whole Lua applications from the command line.". I'm not sure if that means it's only for running simple Lua applications.

Anyway, I followed the instructions on the website and now I have an exe and dll with no idea what I'm meant to do with them. Will I just replace my current Lua lib with the LuaJIT one? What's the deal with all those files I had to copy into that lib folder?

Sorry for being so clueless on this one. :(
