SUMMARY="A powerful, fast, light-weight, embeddable scripting language"
DESCRIPTION="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."
