;;; 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:

(message "Using load-path %s" load-path)
(load "paths.el")
(load "site-init" t)

(let ((attr (file-attributes rmail-spool-directory))
      modes)
  (or (eq t (car attr))
