LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. LaTeX is the de facto standard for the communication and publication of scientific documents.
This program has been written in frustration because some constructs in LaTeX are sometimes non-intuitive, and easy to forget. It is _not_ a replacement for the built-in checker in LaTeX; however it catches some typographic errors LaTeX oversees. In other words, it is Lint for LaTeX. Filters are also provided for checking the LaTeX parts of CWEB documents.
Asymptote is a powerful descriptive vector graphics language that provides a natural coordinate-based framework for technical drawing. Labels and equations are typeset with LaTeX, for high-quality PostScript output.
TexPoint is a Microsoft Powerpoint and Word add-in that enables the easy use of Latex symbols and mathematical formulas in Powerpoint presentations and Word documents.
Bibster is a Java-based system which assists researchers in managing, searching, and sharing bibliographic metadata (e.g. from BibTeX files) in a peer-to-peer network.
PiX, a collection of batch utilities for GNU/Linux and similar platforms, creates mathematically accurate figures, plots, and movies using easy-to-learn syntax. The output is expressly suitable for use with LaTeX; figures may be written in a LaTeX picture environment containing PSTricks, tikz, or eepic macros, or as vector (EPS or PDF) image files.
PGF is a TeX macro package for generating graphics. It is platform- and format-independent and works together with the most important TeX backend drivers, including pdftex and dvips. It comes with a user-friedly syntax layer called TikZ.
