NEdit, the Nirvana editor, is a popular 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 restricted licence, but today it is distributed under the GNU General Public License, and developed as an independent open source project by a team of developers.
