           A list of web servers used by `builtins.fetchurl` to obtain files by
-          hash. The default is `http://tarballs.nixos.org/`. Given a hash type
-          *ht* and a base-16 hash *h*, Nix will try to download the file from
-          *hashed-mirror*/*ht*/*h*. This allows files to be downloaded even if
-          they have disappeared from their original URI. For example, given
