> Awesome, will have to give this a try sometime.  I recommend that you try putting this on the web somewhere, such as Github and luaforge, so that changes can be tracked and a better authoritative src/name can be preserved. It would also be important to apply a license so it can reasonably be used in real projects.  I recommend MIT and/or public domain.
