Lua is a very interesting small programming language, in the same way as Perl, Python, Ruby, and Tcl are - i.e. a dynamically-typed “scripting language”. Here’s the blurb:
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.
