+ (description "@command{xwhite} is a command line tool for adjusting the colour
+balance of screen. It is based on xrandr's gamma correction and brightness adjustment.
+As such, it can only be used for X displays and not Wayland displays. It is typically
+used for tuning the color balance and color temperature. It has a similar function as
+@command{redshift -P -g R:G:B -O temperature}, but @command{xwhite} is more flexible
+in that it does not keep the white color fixed, suitable for setting the white color
+to an arbitrary balanced color.")
