Only applicable when using manual sunset/sunrise times. -g <gamma> Set gamma (default: 1.0). RUNTIME CONTROL Sending SIGUSR1 to wlsunset causes it to cycle through the following modes: 1. Forced use of the high temperature. 2. Forced use of the low temperature. 3. Automatic temperature calculation, the default behavior. EXAMPLE # Beijing lat/long. wlsunset -l 39.9 -L 116.3 Greater precision than one decimal place serves no purpose (https://xkcd.com/2170/) other than padding the command-line.
