vx is a helper library for using Verge under Lua. It wraps Verge's functionality in a way that makes it more usable in dynamic scripting language like Lua, adds object-orientation through metatables, and has garbage collection so resource management requires less frees later.

It is the recommended way to use Lua in Verge, although the low-level access remains there for those who prefer it or need it in spots.
