Granule explanations

Does anyone know where I can find a more detailed explanation of the contents of the various Navision granules for 3.10? My NSC sent me a copy of the Navision Price List Explanation which has all the granules available for 3.10 and a very general description of what each granule does, but I was looking for more detail on what each granule is capable of doing and what it adds to the system overall. I am just looking to evaluate our requirements against the granule before asking a million questions of our NSC.
