 /* Return a Store object to access the Nix store denoted by
    ‘uri’ (slight misnomer...). Supported values are:
 
-   * ‘direct’: The Nix store in /nix/store and database in
+   * ‘local’: The Nix store in /nix/store and database in
      /nix/var/nix/db, accessed directly.
 
    * ‘daemon’: The Nix store accessed via a Unix domain socket
      connection to nix-daemon.
 
+   * ‘auto’ or ‘’: Equivalent to ‘local’ or ‘daemon’ depending on
+     whether the user has write access to the local Nix
+     store/database.
+
    * ‘file://<path>’: A binary cache stored in <path>.
 
-   If ‘uri’ is empty, it defaults to ‘direct’ or ‘daemon’ depending on
-   whether the user has write access to the local Nix store/database.
-   set to true *unless* you're going to collect garbage. */
