Packing and unpacking resource for TGEA

I want to pack all resources under my TGEA project into a file,maybe data.cgf.but i don't know how to load resource package to project,i trace the engine,find out resource manage system in engine is so complex,i can't find the proper interfaces which help us load resouce data from memory,or make unpacking easy! who has experiences or schemes about this, shares with me!


thanks
