;;; Commentary:

;; If these settings are not right, override them with `setq'

		     ;; as configure-info-directory (which is usually true)
		     ;; and Emacs has been installed (also usually true)
		     ;; then the list will end with two copies of this;
		     ;; which means that the last dir file Info-insert-dir
		     ;; finds will be the one in this directory.
