;;; 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.
