+%description
+Query and change monitor settings
+
+ddcutil communicates with monitors implementing MCCS (Monitor Control Command
+Set), using either the DDC/CI protocol on the I2C bus or as a Human Interface
+Device on USB.  In general, anything that can be controlled using a monitor's
+on-screen display can be controlled by this program.  Examples include 
+changing a monitor's input source and adjusting its brightness.
