Lua is a programming language originally designed for extending
applications, but also frequently used as a general-purpose,
stand-alone language.

Lua combines simple procedural syntax (similar to Pascal) with powerful
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 ideal for configuration,
scripting, and rapid prototyping. Lua is implemented as a small library
of C functions, written in ANSI C, and the implementation goals are
simplicity, efficiency, portability, and low embedding cost.
