;;; Commentary:
;; This is loaded into a bare Emacs to create the blessmail script,
;; which (on systems that need it) is used during installation
;; to give appropriate permissions to movemail.
;;
;; It has to be done from lisp in order to be sure of getting the
;; correct value of rmail-spool-directory.
;;; Code:

modes)
