359 the clean but heavy parport handling is not an option. The
360 drawback is a reduced portability and the impossibility to
361 daisy-chain other parallel port devices.
363 Don't say Y here if you said Y or M to i2c-parport. Saying M to
364 both is possible but both modules should not be loaded at the same
