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.
The SeaMonkey project is a community effort to develop an all-in-one Internet application suite. It contains an Internet browser, email and newsgroup client with an included Web feed reader, HTML editor, IRC chat, and Web development tools, and is sure to appeal to advanced users, Web developers, and corporate users. It uses much of the Mozilla source code powering such successful siblings as Firefox, Thunderbird, Camino, Sunbird, and Miro.
RADpage is a rapid application development system for dynamic, data-driven Web applications. It directly operates inside the browser without requiring a client-dependent development environment. RADpage comes as an Apache module or a CGI, includes a powerful HTML/XML like object-oriented programming language called heitml (pronounced "Hi-TML"), and more than 150 Web application components. Development is done on a fully functional application instead of requiring the edit-save-browse cycle associated with conventional client-side development environments. The RADpage editor stores application pages in readable well-formed XML or upon request in HTML for editing with HTML editors.
X-Tract is an XML Script processor. XML Script is a fully XML compliant language, specifically designed for handling XML data.

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.
SATFORM is a forms processor which provides a facility to print word processor-quality letters/reports by merging a data source with a template form. The output is suitable for HP LaserJet III (PCL) or later compatible printers. SATFORM uses an HTML-style markup system (SAT/ML) to define document template forms. It is also possible to make use of SAT/ML formatting to process embedded SAT/ML tags using the companion SATFILTER utility.
