;;; Commentary:

;; `M-x report-emacs-bug ' starts an email note to the Emacs maintainers
;; describing a problem.  Here's how it's done...

;;; Code:

  :group 'mail)

;; >> These should be addresses which are accessible to your machine,
;; >> otherwise you can't use this file.  It will only work on the
;; >> internet with this address.

;; XEmacs: changed address
(defcustom report-emacs-bug-address ""
  "*Address of mailing list for XEmacs bugs."
  :group 'emacsbug
  :type 'string)

;; XEmacs: changed variable name
