Having such a code in your `.emacs' file:

--8<---------------cut here---------------start------------->8---
;; Org-style folding for a `.emacs' (and much more)

(defun my-outline-regexp ()
  "Calculate the outline regexp for the current mode."
  (let ((comment-starter (replace-regexp-in-string
                          "[[:space:]]+" "" comment-start)))
    (when (string= comment-start ";")
      (setq comment-starter ";;"))
    (concat comment-starter "[*]+ ")))

(defun my-outline-minor-mode-hook ()
  (interactive)
  (setq outline-regexp (my-outline-regexp))

  ;; highlight the headings
  (let ((heading-1-regexp
          (concat (substring outline-regexp 0 -1) "\\{1\\} \\(.*\\)"))
        (heading-2-regexp
          (concat (substring outline-regexp 0 -1) "\\{2\\} \\(.*\\)"))
        (heading-3-regexp
          (concat (substring outline-regexp 0 -1) "\\{3\\} \\(.*\\)"))
        (heading-4-regexp
          (concat (substring outline-regexp 0 -1) "\\{4,\\} \\(.*\\)")))
    (font-lock-add-keywords
     nil
     `((,heading-1-regexp 1 'org-level-1 t)
       (,heading-2-regexp 1 'org-level-2 t)
       (,heading-3-regexp 1 'org-level-3 t)
       (,heading-4-regexp 1 'org-level-4 t)))))

(add-hook 'outline-minor-mode-hook
          'my-outline-minor-mode-hook)
--8<---------------cut here---------------end--------------->8---

... and adding "outline-minor" as a cookie or local variable in the file where
you want to use the `org-level-*' titles.

In my case, I have this at the bottom of my `.emacs' file:

--8<---------------cut here---------------start------------->8---
;; This is for the sake of Emacs.
;; Local Variables:
;; coding: utf-8
;; mode: emacs-lisp
;; mode: outline-minor
;; ispell-local-dictionary: "american"
;; End:

;;; .emacs ends here
--8<---------------cut here---------------end--------------->8---

Now, you can add `;;*' and `;;**', etc. as headings in your `.emacs' and cycle
using `M-tab', `M-left' and `M-right' will collapse or expand all headings
respectively.

See the thread "Org-style folding for a .emacs" discussed here in mid-July:
