Richard Stallman, industry activist and founder of the Free Software Foundation (FSF) has - once again - relinquished his role as maintainer of the phenomenally successful GNU Extensible, Customizable, Display Editor (Emacs).
He has stepped down from the role before, with three others assuming responsibility since he wrote Emacs in 1984. Even now, Stallman's hinted he would continue to be involved in Emacs development, although he wants to spend more time on other projects.
Stallman, an outspoken advocate of free as opposed to open source software, devised GNU Emacs to create an extensible editor for developers. It was released under the GNU free software project and has grown from its original Unix base to become one of the most widely used code editors. Although written in C, GNU Emacs draws on the ideas of extensibility used in languages such as Lisp.
