This is a modified version of KopiLua, with packaging changes and a lot of bug fixes. See README for the original author's comments, and COPYRIGHT for his licensing terms.
I also included the LuaTestMore test suite, most of which passes now. It's rigged up with nunitlite, and can be launched through Resharper, through the standalone test harness app that's part of the solution, or through the Unity project that's also provided as a demonstration that these tests all pass from within Unity too.
You may also be interested in KopiLuaInterface, which is a port of LuaInterface on top of this version of KopiLua, and the Unity demo app here which shows it all in action within the Unity Webplayer (which is only possible with a pure C# Lua implementation): http://gfootweb.webspace.virginmedia.com/LuaDemo/
