Ok, suppose we do it just for yourself. I've never installed emacs
(what a shame) and so I can't really help you there (though intuition
tells me that defaults.el might be right).

The auto-mode-alist consists of a list of pairs associating file
name patterns with modes

(..... ("\\.c$" . c++-mode) ("\\.doc$" . nroff-mode) .....)

would be what you want. I have things like this in my .emacs, e.g.

;;; all files ending ".n(roff)", ".doc(ument)" are assumed to be for nroff.
(if (assoc "\\.n$" auto-mode-alist)
    nil
  (nconc auto-mode-alist '(("\\.n$" . nroff-mode))))
(if (assoc "\\.doc$" auto-mode-alist)
    nil
  (nconc auto-mode-alist '(("\\.doc$" . nroff-mode))))


(plus some others....)


Hope this is of some help

Tony
