-# This file is only relevant for Nix and NixOS users.
-# What's actually meant by "Nix" here is not UNIX, but the *package manager* Nix, see https://nixos.org/.
-# If you are
-#   on macOS (and not using nix-darwin)
-#   or on Windows (and not using Nix in WSL),
-# you can carelessly ignore this file.
-#
-# Otherwise, if you *do* use Nix the package manager,
-# this file declares
-#   common dependencies
-#   and some nice tools
-# which you'll most likely need when working with wgpu.
-# Feel free to copy it into your own project if deemed useful.
-#
-# To use this file, just run `nix-shell` in this folder,
-# which will drop you into a shell
-# with all the deps needed for building wgpu available.
-#
-# Or if you're using direnv (https://direnv.net/),
-# use `direnv allow` to automatically always use this file
-# if you're navigating into this or a subfolder.
