# This is a script to set my external monitor's brightness
# to high (70%) or low (40%) easily. It uses ddcutil to access
# the monitor's settings. When used in conjunction with heliocron,
# it can manage the monitor brightness based on sunrise or sunset,
# which can be useful if you like to work in natural light.
