Moving from ClanceysLib to the Xamarin InAppPurchase component

Hi,

My old version of an app used ClanceysLib to help with the maze that is Apple's InAppPurchase system. Much of this has been deprecated with iOS 7 and there isn't an update of ClanceysLib available (that I can see).

Is there a simple how to on moving from ClanceysLib to the Xamarin InAppPurchase component anywhere?
