27 ;; The following defines an association list for text to be
28 ;; automatically inserted when a new file is created, and a function
29 ;; which automatically inserts these files; the idea is to insert
30 ;; default text much as the mode is automatically set using
34 ;; (add-hook 'find-file-hook 'auto-insert)
35 ;; setq auto-insert-directory to an appropriate slash-terminated value
37 ;; You can also customize the variable `auto-insert-mode' to load the
38 ;; package. Alternatively, add the following to your .emacs file:
39 ;; (auto-insert-mode 1)
