ExtendSMIME is designed to be used with Gnus in Emacs. It enhances DefaultEncrypt (emacs-default-encrypt) to support S/MIME (Secure/Multipurpose Internet Mail Extensions) via LDAP (Lightweight Directory Access Protocol). Before a message (e.g., email) is sent, ExtendSMIME searches for missing certificates via LDAP and imports them into gpgsm. When certificates for all recipients are available, DefaultEncrypt automatically encrypts the message. For details and instructions on how to use ExtendSMIME, please refer to the home page or read the comments in the source file, jl-smime.el.

Display the recursive size of directories in Dired. This file defines a minor mode dired-du-mode to show the recursive size of directories in Dired buffers.

For directories where the user doesn't have read permission, the recursive size is not obtained. Once this mode is enabled, every new Dired buffer displays recursive dir sizes.
