GLE (Graphics Layout Engine) is a graphics scripting language designed for creating publication quality figures (e.g., a chart, plot, graph, or diagram). GLE supports various chart types (including function plot, histogram, bar chart, scatter plot, contour plot, color map, and surface plot) through a simple but flexible set of graphing commands. More complex output can be created by relying on GLE's scripting language, which is full featured with subroutines, variables, and logic control. GLE relies on LaTeX for text output and supports mathematical formulae in graphs and figures.
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.
TkDVI is a DVI previewer built with the Tcl/Tk toolkit. It can use multiple windows to display multiple pages at the same time (which can come from multiple DVI files sharing a common font repository). Each window can show either a single page, two facing pages (as in a book) or sixteen reduced pages in the space of one, to check page breaks and positioning of floating items. TkDVI supports many features from xdvi, such as a magnification glass, but also adds interesting stuff like a gv-like page selector and a `rubber line' for measuring distances. TkDVI is based on a reusable Tk `image type' for DVI files which can easily be incorporated in other programs, and it is straightforward to customize and extend TkDVI itself.
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.
glatex is a small program designed to help you to edit your LaTeX document files (sources, styles, bibliography, figures, postscript images, etc.). It maintains a list of all your editable files in order to allow you to edit them quickly. But you can also launch the compilator, viewer, and print commands, and it allows you to have document templates for creating new projects. It is not intended to manage the files themselves. For example, if you move a file from one directory to another, you'll have to remove it from the list and re-add it from its new location.
RefDB is a reference database and bibliography tool for SGML, XML, and LaTeX documents. Command-line tools allow interactive or scriptable access to the data which are stored in a SQL database. RefDB can also be accessed through a Web interface, a SRU interface, or via editor extensions (Emacs/vim). Libraries for Perl and PHP are available for programmers. RefDB provides sophisticated character encoding handling, using Unicode by default.
