%description
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.
