The high typesetting quality still goes through for automatically generated formulas, which makes TeXmacs suitable as an interface for a number of computer algebra systems including GNU Maxima. TeXmacs also supports the Guile/Scheme extension language, so that you may customize the interface and write your own extensions to the editor.
TeXmacs currently runs on PC's and PPC's under GNU/Linux (a >200MHz processor and >32Mb of memory are recommended) and on Sun computers. Converters exist for TeX/LaTeX and they are under development for HTML/MathML/XML. In the future, TeXmacs is planned to evolve towards a complete scientific office suite, with spreadsheet capacities, a technical drawing editor and a presentation mode.
