;;   (add-hook 'c-mode-hook 'update-copyright)

;;; Code:

(defun update-copyright ()

  (interactive)
  (save-excursion
    (let ((year (substring (current-time-string (current-time)) 20 24))
          (user user-full-name))
      (replace-regexp
       (concat "     \\(200.\\) *" user)
       (concat "\\1-" year " " user))
      (replace-regexp
       (concat "\\(200.-\\)?200. *" user)
