  Installation
  ============
  Every configuration file you want themer to update needs to be added to `~/.config/themer/templates/<name>/config.yaml`.
  The rendered config file will appear in `~/.config/themer/current/` and the configration file should be symlinked there, e.g.:

      $ touch ~/.config/themer/templates/i3/Xdefaults.tpl
      $ echo "Xdefaults.tpl: Xdefaults" >> ~/.config/themer/templates/i3/config.yaml
      $ ln -s ~/.config/themer/current/Xdefaults ~/.Xdefaults

  Now you can use themer to generate a theme and apply it:

      $ themer generate newtheme wallpaper.jpg
      Activate now? yN y
