  26 ;;; Commentary:
  27
  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.
  33 ;;
  34 ;;  To use:
  35 ;;     (add-hook 'find-file-hook 'auto-insert)
  36 ;;     setq auto-insert-directory to an appropriate slash-terminated value
  37 ;;
  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)
