texmacs binary package in Ubuntu Trusty powerpc

 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 a 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.
