Data driven sprite collections.
Compatible with 2D Toolkit 2.4 and 2.5.
It is far from complete and is now unsupported - but it works and is a nice way of creating and managing sprite collections and animations using a script. Its unlikely to have any more work done on it by ourselves, but perhaps could do better with more active user contributions. Its also a good reference for creating and managing sprite collections from code.
