Introduction
Rudel is a collaborative editing environment for GNU Emacs. It supports multiple backends to enable communication with other collaborative editors using different protocols (most notably Gobby). For details about supported protocols and compatibility with other implementations, have a look at the compatibility page.
Since Rudel is not an application, but an extension to Emacs, it is not started and used like most applications (not even Emacs applications like Gnus). Rudel mostly works in the background to change the behavior of the set of Emacs buffers for which it has been activated. These do not even have to have a certain minor mode enabled.
The user interface of Rudel consists of a set of key bindings, a menu entry and some visual status indicators, which are added to the text and mode line of buffers for which Rudel has been activated. This user interface is realized as a global minor mode.
