# NOTE: to convert to a poetry2nix env like this here are the
# steps:
# - install poetry in your system nix config
# - convert the repo to use poetry using `poetry init`:
# https://python-poetry.org/docs/basic-usage/#initialising-a-pre-existing-project
# - then manually ensuring all deps are converted over:
# - add this file to the repo and commit it
