+;;; 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.
