"""Displays the current color temperature of redshift
Requires the following executable:
* redshift
Parameters:
* redshift.location : location provider, either of 'auto' (default), 'geoclue2',
'ipinfo' or 'manual'
'auto' uses whatever redshift is configured to do
* redshift.lat : latitude if location is set to 'manual'
* redshift.lon : longitude if location is set to 'manual'
* redshift.show_transition: information about the transitions (x% day) defaults to True
* redshift.adjust: set this to 'true' (defaults to false) to let bumblebee-status adjust color temperature, instead of just showing the current settings
