	<longdescription>
		ddcutil primarily uses DDC/CI (Display Data Channel Command Interface)
		to communicate with monitors implementing MCCS (Monitor Control Command
		Set) over I2C. Normally, the video driver for the monitor exposes the
		I2C channel as devices named /dev/i2c-n. Alternatively, there is initial
		support for monitors (such as Apple displays) that implement MCCS using
		a USB connection.
