gnus-desktop-notify provides a simple mechanism to notify the user when new messages are received. To get started, place the following configuration snippet in your ~/.gnus.el configuration file:

(require 'gnus-desktop-notify)
(gnus-desktop-notify-mode)
(gnus-demon-add-rescan)
;; Alternatively, configure the period and idle times specifically, e.g.:
;; (gnus-demon-add-handler 'gnus-demon-scan-news 10 1)

The above causes Gnus to scan all configured groups every two hours when Emacs has been idle for one hour, with desktop notifications emitted for new messages received.

This package provides a minor mode to displays page delimiters which usually appear as ^L glyphs on a single line as horizontal lines spanning the entire window. In comparison to emacs-form-feed, this fork does not have configurable line width; however, it always displays correctly, even if you have multiple windows showing the same buffer, and will never cause side scrolling since the form feed only occupies two spaces. It also only affects form feeds at the beginning of the line.

This package provides syntax highlighting, a minor mode for listing type errors via Flycheck, as well as REPL support for Carp.

This library adds the possibility for ad-hoc applying highlighting to any face in GNU Emacs. The functionality of this library depends on overlays, which by default are not picked up when copy-pasting text from buffer to buffer.

Butler provides an interface to connect to Jenkins continuous integration servers. Users can specify a list of server in the butler-server-list variable and then use M-x butler-status to view the build status of those servers' build jobs, and possibly to trigger build jobs.
