This package provides the auto-dark-mode minor mode, which enables automatic switching between two user-defined (customizable) themes. This transition occurs seamlessly in response to dark mode being enabled or disabled in the desktop preferences (such as in GNOME). It uses DBus to query the system configured value. To enable it, put the following snippet to your Emacs configuration file:

(require auto-dark)
(auto-dark-mode t)

To customize the themes used, visit M-x customize-group auto-dark.

ExtendSMIME is designed to be used with Gnus in Emacs. It enhances DefaultEncrypt (emacs-defaultencrypt) 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.
