Adds a -p flag which tells redshift-scheduler to print the temperature that it thinks should be set right now, calculated according to the given rules.
Note: redshift-scheduler prints the calculated temperature that corresponds to the given rules, and not the temperature currently set via redshift. If redshift-scheduler is not running, then there would obviously be a mismatch.
Adds support for redshift >= 1.12.
Be more quiet by default. To get more debug information, pass --debug.
