Org-transclusion lets you insert a copy of text content via a file link or ID link within an Org file. It lets you have the same content present in different buffers at the same time without copy-and-pasting it.

Org-transclusion keeps your files clear of the transcluded copies, leaving only the links to the original content.

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.

This package provides a Helm interface for selecting xref results.

emacs-validate-html installs the command validate-html, which sends the current buffer to the World Wide Web Consortium’s HTML Validator service and displays the results in a buffer in Compilation mode.

The code provides a abbreviation expansion for Emacs. It is fairly similar to Dabbrev expansion, which works based on the contents of the current buffer (or other buffers).

Predictive abbreviation expansion works based on the previously written text. Unlike dynamic abbreviation, the text is analysed during idle time, while Emacs is doing nothing else.

This package provides an Emacs minor mode that puts writing in the center.
