;;; Commentary:
;;; Abstract:
;;;
;;; The following defines an association list for files to be
;;; automatically inserted when a new file is created, and a function
;;; which automatically inserts these files; the idea is to insert
;;; default files much as the mode is automatically set using
;;; auto-mode-alist.
;;;
;;; The auto-insert-alist consists of dotted pairs of
;;; ( REGEXP . FILENAME ) where REGEXP is a regular expression, and
;;; FILENAME is the file name of a file which is to be inserted into
;;; all new files matching the regular expression with which it is
;;; paired.
;;;
;;; To use:
;;; load autoinsert.el
;;; setq auto-insert-directory to an appropriate value, which
;;; must end in "/"

CONDITION maybe a regexp that must match the new file's name, or it may be
a symbol that must match the major mode for this element to apply.
