# Nix Flake exporting an attribute to build the thesis in a Nix derivation.
# Also exporting a dev shell to get the relevant tooling to build the
# thesis traditionally on the shell.
#
# Make sure to configure your `nix` with:
# `experimental-features = flakes nix-command`
# in order to be able to use flakes.
#
# Feel free to ping "@phip1611" for maintenance guidance and questions.
