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