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