SpaceManager - Fantastic Library for Cocos2D and Chipmunk Integration for the iPhone

I've been struggling for some time writing my first Cocos2D game for the iPhone using Chipmunk Physics. The problem is the constant back and forth between Objective C and C. Now someone has solved this problem for me by releasing SpaceManager. Here's a link to the official site....it's a great piece of work. Many thanks to the coders who wrote this.... http://code.google.com/p/chipmunk-spacemanager/
