  22 ;;;  Abstract:
  23 ;;;
  24 ;;;  The following defines an association list for files to be
  25 ;;;  automatically inserted when a new file is created, and a function
  26 ;;;  which automatically inserts these files; the idea is to insert
  27 ;;;  default files much as the mode is automatically set using
  28 ;;;  auto-mode-alist.
  29 ;;;
  30 ;;;  The auto-insert-alist consists of dotted pairs of
  31 ;;;  ( REGEXP . FILENAME ) where REGEXP is a regular expression, and
  32 ;;;  FILENAME is the file name of a file which is to be inserted into
  33 ;;;  all new files matching the regular expression with which it is
  34 ;;;  paired.
  35 ;;;
  36 ;;;  To use:
  37 ;;;     load autoinsert.el
  38 ;;;     setq auto-insert-directory to an appropriate value, which
  39 ;;;       must end in "/"
