 Lupan's config files
 ====================

-Short answer: [screenshots here](https://lupan.pl/lupan-themes/).
-
-My configuration allows to switch between my 6 themes using a shell
-script bound to a key stroke (`super + F6` for switching themes in a
-cycle and `super + shift + F6` for selecting one with `dmenu`).  The
-theme is applied to *bspwm*, *Polybar*, *Alacritty*, *Emacs*, and
-*Gtk3* (with support for reloading themes in active *Gtk3*
-applications, but I currently use only two *Gtk3* themes: one dark and
-one light).
-
-You can see the screenshots of my whole workspace with each of the
-themes applied on the page describing [my Emacs
-themes](https://lupan.pl/lupan-themes/).  For the Emacs theme
-reloading I use simple helper Emacs function `my-select-theme`
-available from [Toggle between dark and light themes with a
-key](https://lupan.pl/dotemacs/#toggle-between-dark-and-light-themes-with-a-key)
-section of my Emacs config (also available in corresponding [GitHub
-repo](https://github.com/lukpank/.emacs.d).
