fornjot

# Defines an environment for `nix-shell` for developing Fornjot on NixOS.
#
# This is not complete, and probably not the correct NixOS way to do it either.
# It's just what works for me (@hannobraun) in combination with my local
# environment. Pull requests to improve this (best coupled with thorough
# explanations, because I understand very little about Nix/NixOS) welcome!
