25 | ;; The following defines an association list for text to be |
26 | ;; automatically inserted when a new file is created, and a function | |
27 | ;; which automatically inserts these files; the idea is to insert | |
28 | ;; default text much as the mode is automatically set using | |
29 | ;; auto-mode-alist. | |
30 | ;; | |
31 | ;; To use: | |
32 | ;; (add-hook 'find-file-hooks 'auto-insert) | |
33 | ;; setq auto-insert-directory to an appropriate slash-terminated value | |
