Lua is a programming language originally designed for extending applications, but is also frequently used as a general-purpose, stand-alone language.
Lua combines procedural syntax (similar to Pascal) with data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, interpreted from byte codes, and has automatic memory management, making it suitable for configuration, scripting, and rapid prototyping. Lua is implemented as a small library of C functions, written in ANSI C.
