editors/TeXmacs - The NetBSD Packages Collection

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, 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 evoluate towards
a complete scientific office suite, with spreadsheet capacities, a
technical drawing editor and a presentation mode.
