-# Environment setup for Nix shells #
-####################################
-
-# From https://github.com/direnv/direnv/wiki/Nix#persistent-cached-shell
-#
-# Usage: use_nix [...]
-#
-# Load environment variables from `nix-shell`.
-# If you have a `default.nix` or `shell.nix` one of these will be used and
-# the derived environment will be stored at ./.direnv/env-<hash>
-# and symlink to it will be created at ./.direnv/default.
-# Dependencies are added to the GC roots, such that the environment remains persistent.
-#
-# Packages can also be specified directly via e.g `use nix -p ocaml`,
-# however those will not be added to the GC roots.
-#
-# The resulting environment is cached for better performance.
-#
-# To trigger switch to a different environment:
-# `rm -f .direnv/default`
-#
-# To derive a new environment:
-# `rm -rf .direnv/env-$(md5sum {shell,default}.nix 2> /dev/null | cut -c -32)`
-#
-# To remove cache:
-# `rm -f .direnv/dump-*`
-#
-# To remove all environments:
-# `rm -rf .direnv/env-*`
-#
-# To remove only old environments:
-# `find .direnv -name 'env-*' -and -not -name `readlink .direnv/default` -exec rm -rf {} +`
