How do I convert a XUL extension to a firefox SDK addon?

I have an addon folder structure like this

-components
-chrome
-defaults
-modules
-chrome.manifest
-install.rdf

      

        
        
        
      

    

I want to convert it like this and use sdk firefox

-data
-lib
-test
-package.json

      

        
        
        
      

    

How can i do this?
