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. | |

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. | |
