* About this Emacs configuration

Configuration uses org-mode to tangle its contents to init.el and then
be used by emacs. I use guix home for my emacs config on gnu guix
system.

If you see :tangle nil it means that snippet is not used anymore, but
it is left because it might be valuable in a future for me.

This configuration is available here:
https://w96k.dev/emacs.html

The git source code is hosted on Sourcehut:
https://git.sr.ht/~w96k/dotfiles/tree/master/item/emacs

The license of emacs config and dotfiles is CC0 which is Public Domain.
