(Plug:) You might want to take a look at the lua debugger
(still alpha, but quite usable) at
http://primero.ricilake.net:8008/ldb/index.html
Why does the official lua distribution still have the `debug' library?
I think it is ugly if lua has that library. Most of the time we can
debug the scripts via some debugging tools.
