Removing Extensions


Hi, I just started with cocos2dx-2.2 and the first project I created has all these extensions (CocoStudio/AssetsManager/CCBReader/GUI) etc. I am not sure I need them for my first game and also sure that their presence is contributing to an increased binary size. So my question is how do I remove them without breaking anything ? I use Xcode to build ios and eclipse for Android. I believe I will also have to change files, etc.
