      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.
