GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
Asymptote is a powerful descriptive 2D and 3D vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications.
TeX Live is an easy way to get up and running with TeX. It provides a comprehensive TeX system with binaries for most flavors of Unix, including GNU/Linux, and also Windows. It includes all the major TeX-related programs, macro packages, and fonts that are free software, including support for many languages around the world.
LaTeX is a document preparation system for high-quality typesetting based on TeX. It is most often used for medium-to-large technical or scientific documents, but it can be used for almost any form of publishing. It is not a word processor; instead, it encourages authors not to worry too much about the appearance of their documents, but to concentrate on getting the right content.
The cb2Bib is a tool for rapidly extracting bibliographic references from email alerts, journal Web pages, and PDF files. It facilitates the capture of single references from unformatted and non standard sources. Output references are written in BibTeX. Article files can be easily linked and renamed by dragging them onto the cb2Bib window. Additionally, it permits editing and browsing BibTeX files, citing references, searching references and the full contents of the referenced documents, inserting bibliographic metadata to documents, and writing short notes that interrelate several references.
dvipng makes PNG or GIF graphics from DVI files obtained from TeX and its relatives. Its benefits include speed; it uses very fast bitmap-rendering code for DVI files. Furthermore, it does not read the postamble, so it can be started before TeX finishes. It supports PK, VF, PostScript Type1 (via FreeType or t1lib), and TrueType fonts (via FreeType), color specials, can render CJK fonts, and more.
ASCIIMathML is a script that converts calculator-style ASCII math notation (and many LaTeX formulas) to Presentation MathML while your Web page loads. It works with HTML and XHTML files in Mozilla/Firefox/Netscape 7+ browsers, as well as in Internet Explorer 6 with MathPlayer. For example, the solutions for the equation 'ax^2+bx+c=0' are expressed in the HTML file as '(-b +- sqrt(b^2 - 4ac))/(2a)', and display as nicely formatted MathML. The script can be easily used in wikiservers and blogs, as a rudimentary MathML editor (with instant preview), and to preview math formulas as they are typed into a Web page input area.
prerex is an interactive (command-line) editor and a LaTeX macro support package that can be used to create very attractive and readable prerequisite charts. A graphical front-end for the editor also provides a prerex-enabled PDF viewer. A prerequisite chart is a network of course boxes linked by prerequisite and co-requisite arrows.
rtf2latex2e is an utility to convert RTF files from popular word processors to the LaTeX2e format for those who value quality typesetting. rtf2latex2e uses the RTF reader package by Paul DuBois to parse the RTF code and generates an appropriate LaTeX file. The main features of rtf2latex2e are: detects text style: bold, italic, color, big, small,... reads embedded figures: PICT, WMF, PNG, JPEG,... reads tables: simple to semi- complex equations: reads out Equation Editor equations (courtesy Steve Swanson, http://www.mackichan.com) symbols: converts most greek and math symbols reads footnotes (not in tables yet), and converts hypertext links using the hyperref package.
