Pour ajouter mon petit grain de sel, je peux aussi mentionner TeXmacs http://www.texmacs.org/
GNU TeXmacs is a free scientific text editor, which was both inspired by TeX and GNU Emacs. The editor allows you to write structured documents via a wysiwyg (what-you-see-is-what-you-get) and user friendly interface. New styles may be created by the user. The program implements high-quality typesetting algorithms and TeX fonts, which help you to produce professionally looking documents. The high typesetting quality still goes through for automatically generated formulas, which makes TeXmacs suitable as an interface for computer algebra systems. TeXmacs also supports the Guile/Scheme extension language, which makes it possible to adapt the user interface to specific needs and even to extend the editor. TeXmacs currently runs on PC's under Gnu-linux (a >200MHz processor and >32Mb of memory are recommended) and on sun computers. The editor is more or less compatible with the TeX system and we are improving our interface with computer algebra systems. Subsequently, TeXmacs should also support graphics and hypertext features. GNU TeXmacs is hosted by the Centre de Ressources Informatiques de Haute Savoie, Archamps, France Anne -- http://www-internal.alphanet.ch/linux-leman/ avant de poser une question. Ouais, pour se désabonner aussi.
