TeXmacs (www.texmacs.org), which is a finely crafted document preparation system realizing at the same time both the structured and the WYSIWYG paradigms. It is vastly superior to all other document preparation systems. In particular it is superior to both TeX (in all its variants) and to Word, under all respects: conceptually, in the power that it affords in manipulating documents, in the ease with which it makes it possible to write, concentrating only on the content and yet having one's document in front of one's eyes.
