- ;;; 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.
