While searching for information on Lua, I stumbled up on the website for GameMonkey Script.

What is GameMonkey Script?
GameMonkey is a embedded scripting language that is intended for use in game and tool applications. GameMonkey is however suitable for use in any project requiring simple scripting support. GameMonkey borrows concepts from Lua (www.lua.org), but uses syntax similar to C, making it more accessible to game programmers. GameMonkey also natively supports multithreading and the concept of states.
