I have couple questions about lua files in cataclysm\_code.

First  
lua/autoexec.lua  
class\_definition.lua  
generate\_bindings.lua  
Is these file are shared or used related? This is important cause i am working on this [https://github.com/CleverRaven/Cataclysm-DDA/pull/6225](https://github.com/CleverRaven/Cataclysm-DDA/pull/6225) and almost finished. I need to know in which dir put this files.

Second  
What is main.lua file? user-related or shared?
