NEdit, the Nirvana editor, is a text editor and source code editor for the X Window System. It has an interface similar to text editors on Microsoft Windows and Macintosh, rather than to older UNIX editors like Emacs. It was initially developed by Mark Edel for Fermilab and released under a very restrictive licence, but today it is distributed under the less restrictive GPL-2.0-or-later (plus Motif clause) and is developed as an independent open-source project by a team of developers. Nedit was also distributed with the IRIX operating system.
