25 ;;; Commentary:
27 ;; This is loaded into a bare Emacs to create the blessmail script,
28 ;; which (on systems that need it) is used during installation
29 ;; to give appropriate permissions to movemail.
31 ;; It has to be done from lisp in order to be sure of getting the
32 ;; correct value of rmail-spool-directory.
34 ;;; Code:
36 ;; These are no longer needed because we run this in emacs instead of temacs.
37 ;; (message "Using load-path %s" load-path)
38 ;; (load "paths.el")
39 ;; It is not safe to load site-init.el here, because it might have things in it
40 ;; that won't load properly unless all the rest of Emacs is loaded.
