"lua (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."
