texmacs 1:1.0.6-2ubuntu1 (amd64 binary) in ubuntu edgy

 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.
 .
 This package contains the architecture dependent files.
