f.lux indicator applet

Better lighting for your computer

The f.lux indicator applet fluxgui is an indicator applet to control xflux, an application that makes the color of your computer's display adapt to the time of day, warm at nights and like sunlight during the day. Reducing blue light exposure in the evening can help you fall asleep at night. See https://justgetflux.com/research.html for more details.

This project -- https://github.com/xflux-gui/fluxgui -- is only concerned with the fluxgui indicator applet program, not with the underlying xflux program the indicator applet controls. The xflux program is responsible for actually changing the color of your screen. See https://justgetflux.com/linux.html for more information about xflux.

Change Logs, Versions, Releases

Note changes in ./debian/changelog.

Use version <ver>~pre until ready to release a version. When releasing a version make branch, remove the ~pre suffix from the version strings in the branch, and git tag -a the branch v<ver>.

When releasing the version string needs to be changed in debian/changelog and setup.py, and the release dates needs to be added in debian/changelog.
