@chapter Overview

Inspired by Redshift, Blueshift adjusts the colour
temperature of your monitor according to brightness
outside to reduce eye strain and make it easier to
fall asleep when going to bed. It can also be used
to increase the colour temperature and make the
monitor bluer, this helps you focus on your work.

Blueshift is not user friendly and it is not
meant too be. Blueshift does offer limited
use of command line options to apply settings,
but it is really meant for you to have configuration
files (written in Python 3) where all the policies
are implemented, Blueshift is only meant to provide
the mechanism for modifying the colour curves.
Blueshift neither provides any means of automatically
getting your geographical position; the intention is
that you should implement that in the policy yourself
using library which can do that. Additionally
Blueshift provides not safe guards from making your
screen unreadable or otherwise miscoloured; and
Blueshift will never, officially, add support
specifically for any proprietary operating system.
Blueshift is fully extensible so it is possible to
make extensions that make it usable under unsupported
systems, the base code is written in Python 3 without
calls to any system dependent functions.
If Blueshift does not work for you for any of these
reasons, you should take a look at Redshift.

Blueshift is fully extensible and highly configurable.
