/*
To run:
nix-shell maintainers/scripts/update-dotnet-lockfiles.nix
This script finds all the derivations in nixpkgs that have a 'fetch-deps'
attribute, and runs all of them sequentially. This is useful to test changes
to 'fetch-deps', 'nuget-to-nix', or other changes to the dotnet build
infrastructure. Regular updates should be done through the individual packages
update scripts.
