let
pkgs = import ./../../default.nix (removeAttrs args [ "maintainer" ]);
# This avoids a common situation for maintainers, where due to Git's behavior of not tracking
# directories, they have an empty directory somewhere in `pkgs/by-name`. Because that directory
# exists, `pkgs/top-level/by-name-overlay.nix` picks it up and attempts to read `package.nix` out
# of it... which doesn't exist, since it's empty.
#
# We don't want to run the code below on every instantiation of `nixpkgs`, as the `pkgs/by-name`
# eval machinery is quite performance sensitive. So we use the internals of the `by-name` overlay
# to implement our own way to avoid an evaluation failure for this script.
#
# See <https://github.com/NixOS/nixpkgs/issues/338227> for more motivation for this code block.
