Does anyone know the meaning of the surname Bittner?

I have been looking for the meaning of my surname, Bittner, and all the sites I have tried do not have it listed. Does anyone by chance happend to know what it means? I do know that it is German, but knowing that doesn't seem to be helping me either.
