+<para>The operation <option>--add-fixed</option> adds the specified paths to
+the Nix store.  Unlike <option>--add</option> paths are registered using the
+specified hashing algorithm, resulting in the same output path as a fixed output
+derivation.  This can be used for sources that are not available from a public
+url or broke since the download expression was written.
