(defbackend pickle :stream-type 'character) This creates a new backendcalled name, stream-type describes the type of stream that the backend will serializeto which must be suitable as an argument to open. Magic-number, when present, mustbe of type (unsigned-byte 32) which will be written as a verier for the backend. Fieldsare extra elds to be added to the new class which will be created.
