Lua

Lua is a powerful, fast, lightweight, embeddable scripting language.

Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode for a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping.

Runs on both FAT and HPFS file systems.

Please note that Lua is a noun and not an acronym, it is the Portuguese form of "Luna", or the Portuguese word for the moon in other words and should not be spelled all caps.
