;;; Commentary:

;; Allows updating the copyright year and above mentioned GPL version manually
;; or when saving a file.  Do (add-hook 'write-file-hooks 'copyright-update).

;;; Code:

(defgroup copyright nil
  "Update the copyright notice in current buffer."
  :group 'tools)

(defcustom copyright-limit 2000
  "*Don't try to update copyright beyond this position unless interactive.
`nil' means to search whole buffer."
  :group 'copyright
  :type '(choice (integer :tag "Limit")
		 (const :tag "No limit")))

;; Cleaner to specify Latin-1 coding for this file, and not use both
;; unibyte and multibyte copyright symbol characters?
(defcustom copyright-regexp
