;;; Synched up with: FSF 19.34.
;;; 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:
;; These are no longer needed because we run this in emacs instead of temacs.
;; (message "Using load-path %s" load-path)
;; (load "paths.el")
;; 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.
