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