Hi,

I like the idea of using Lua personally for graphical menu related
scripting and in my opinion it could be additional script that could be
used.

User could in example defined scripting language in a bit same way that
you do that in HTML pages:

lua:"script-filename.lua"

grub:"exec grub-script-filename"

own-extension:"do this and this effect that is integrated to some other
module"

In order to one of those work, you need to load script module that
registers handler for it.

Do anyone have skills to decipher Lua's license is it compatible with
GPLv3 ?
