;; This is loaded into a bare Emacs to create the blessmail script,

;; 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:
;; These are no longer needed because we run this in emacs instead of temacs.

;; It is not safe to load site-init.el here, because it might have things in it
;; that won't load properly unless all the rest of Emacs is loaded.
