liblua

liblua 5.2.4. This is not the latest version, but seems to be the most
compatible version at the time of compiling.

----------------------

Lua is a powerful, efficient, lightweight, embeddable scripting language. It
supports procedural programming, object-oriented programming, functional
programming, data-driven programming, and data 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 with a register-based virtual machine, and has
automatic memory management with incremental garbage collection, making it ideal
for configuration, scripting, and rapid prototyping.
