Lua (programming Language)
Lua ( /ˈluːə/ LOO-ə, from Portuguese: lua meaning "moon"; explicitly not "LUA") is a lightweight multi-paradigm programming language designed as a scripting language with "extensible semantics" as a primary goal. Lua is cross-platform since it is written in ISO C. Lua has a relatively simple C API compared to other scripting languages.
