3`prefer-remote-fetch` is an overlay that downloads sources on a remote builder. This is useful when the evaluating machine has a slow upload while the builder can fetch faster, directly from the source. To use it, put the following snippet as a new overlay:

5```nix
6self: super: (super.prefer-remote-fetch self super)
