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