This is a combination of LuaInterface 2.0.1 with KopiLua 0.1. The idea is to provide a pure C# Lua suite for maximum portability in environments like Unity and XNA.
I believe everything here was originally published under the MIT licence, so that applies to the combination too. See the original COPYRIGHT files in the KopiLua and KopiLuaInterface directories.
Both packages have been modified rather a lot, and I've lost track of what I changed and why. Broadly speaking, though, LuaInterface needed changing to make it work with KopiLua - issues like the distinction between a C function and a C# function being redundant. I also disabled some code that's not suitable for use in Unity's web player.
KopiLua itself had some bugs - I remember specifically some issues with userdata, and some lua_assert calls had lost the '!' from their expressions.
Note that LuaInterface is now up to version 2.0.3, so this snapshot is out of date. KopiLua has also been added to github and extended there by a third party, and it's possible that the most recent version there would be a better base than what I have used so far.
I will try to consolidate my changes better, and see if they can be made less intrusive, so they can more easily be applied to newer versions.
KopiLua won't build without certain #defines, so you can't just put its C# files into a Unity project - you need to build it to a DLL in Visual Studio and put the DLL into your Unity project.
The Unity directory contains a Unity demo app, including the three compiled Kopi DLLs.

However, bear in mind that I'm not a Lua expert and I'm not the original author of either package. Certainly for documentation you should look to the original packages online.
