-This Dired-X feature is obsolete as of Emacs 24.1.  The standard Emacs
-directory local variables mechanism (@pxref{Directory

-When Dired visits a directory, it looks for a file whose name is the
-value of variable @code{dired-local-variables-file} (default: @file{.dired}).
-If such a file is found, Dired will temporarily insert it into the Dired
-buffer and run @code{hack-local-variables}.

-@noindent
-You can set @code{dired-local-variables-file} to @code{nil} to suppress this.
-The value of @code{dired-enable-local-variables} controls if and how these
-local variables are read.  This variable exists so that it may override the
-default value of @code{enable-local-variables}.

-;;
-;; * `dired-extra-startup' is part of the `dired-mode-hook'.
-;;
-;; * `dired-extra-startup' calls `dired-hack-local-variables'
-;;
-;; * `dired-hack-local-variables' checks the value of
-;;   `dired-local-variables-file'
-;;
-;; * Check if `dired-local-variables-file' is a non-nil string and is a
-;;   filename found in the directory of the Dired Buffer being created.
-;;
-;; * If `dired-local-variables-file' satisfies the above, then temporarily
-;;   include it in the Dired Buffer at the bottom.
-;;
-;; * Set `enable-local-variables' temporarily to the user variable
-;;   `dired-enable-local-variables' and run `hack-local-variables' on the
-;;   Dired Buffer.
