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