Addon Language question

[Makno]

I am interested in making a new addons for this game. I found one of my favorite addon no longer working for Warband. So I want to change it to make it work with ROR. What language that the addon is using? LUA?

Most mods are using file ending in .xml , .lua and .mod

So what you would be looking at is XML and LUA
