;;; Commentary: Provides a `footnote-init' usable as
;;; footnote-mode-hook, which reads in existing
;;; footnodes. Customize `footnote-mode-hook' with this
;;; function should do the right thing when switching
;;; footnote-mode on.
;; Changes to previous version: Bugs fixed which
;; occurred if `footnote-init' was called with buffer
;; without footnotes.
;;; Code:
(require 'footnote)
