Modulemanager in mod gamedata folders

[Rockhem]

What is up with module manager being in some mods .zip folders, do i have to install it?

Module manager comes with some mods so they can overwrite the vanilla part.cfg files without completely replacing them which allows multiple mods that overwrite the same file to be compatible with each other. From what I've gathered you don't need to do anything with it, just leave it alone. More info on it can be found in it's thread although it's list of what mods use it isn't completely up to date.
