World Downloader Mod

[TrapQueen]

I was wondering if anyone knew how to put the World Downloader mod into a mod pack becuase I dont know how becuase it doesn't have a jar file its one of those mods that you have to put in the minecraft jar and then have to delete meta inf. it is for minecraft 1.7.10 

If anyone knows anything about this it would help a ton

This is the link to the mod main page too:
