Compiling TGB into TGE/TSE..

I'm trying to compile my TGB into TGE. I've done some searching in the forums but the only thing I've found is where a GG says just drop everything under engine into your TGE source and compile. Well, I don't think it's quite that easy. There are many folders under engine in the TGB Pro directory and I'm not sure which ones to add. Should I just add the stuff under engine/source into my TGE project?

I remember a post a while back about someone doing this very thing but I guess I didn't bookmark it.

Any thoughts?

Thanks,

Steve
