TeX is a typesetting system that incorporates a macro processor. A TeX source document specifies or incorporates a number of macro definitions that instruct the TeX engine how to typeset the document. The TeX engine also uses font metrics generated by Metafont, or by any of several other mechanisms that incorporate fonts from other sources into an environment suitable for TeX. TeX has been, and continues, a basis and an inspiration for several other programs, including e-TeX and PDFTeX. The distribution includes the source of Knuth's TeX book; this source is there to read, as an example of writing TeX ; it should not be processed without Knuth's direct permission.

The package provides a small Perl script to filter the online output from a TeX run, attempting to show only those messages which probably deserve some change in the source. The TeX invocation itself need not change.

This package provides LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX support for the PoiretOne family of fonts, designed by Denis Masharov. PoiretOne is a decorative geometric grotesque with a hint of Art Deco and constructivism. There is currently just a regular weight and an artificially emboldened bold.

This LaTeX3 package based on TikZ helps to generate beautiful Pascal (Yanghui) triangles. It provides a unique drawing macro \pascal which can generate isosceles or right-angle triangles customized by means of different \pascal macro options or the \pascalset macro.

This bundle contains LaTeX classes and packages to create machine readable questionnaires. Metadata is generated for the whole document and it is possible to process created forms fully automatically using the SDAPS main program.

Its features include:

• PDF form generation,

• advanced array like layouting,

• can flow over multiple pages and repeats the header automatically,

• optional document wide alignment of array environments,

• has complex layout features like rotating the headers to safe space,

• ability to exchange rows and columns on the fly,

• different question types: free-form text, single/multiple choice questions, range questions,

• Layouting questions in rows or columns,

• Possibility to pre-fill questionnaires from LaTeX.

The package provides commands to insert French road signs as vector graphics.

This package allows you to typeset monographs and edited volumes for publication with Language Science Press. It includes all necessary files for title pages, frontmatter, main content, list of references and indexes.

This package provides utilities to convert TrueType to TFM and PK fonts: ttf2afm, ttf2pk, ttf2tfm, and ttfdump.

Since version 1.40 pdfTeX supports several colour stacks. This package uses a separate colour stack for footnotes that can break across pages.

The default citation styles use the op.: cit.: form in order to have a shorter reference when a title has already been cited. However, when you cite two entries which share the same booktitle but not the same title, the op.: cit.: mechanism does not work. This package fixes this.

This package provides a simple compilation of the genealogical symbols found in the wasy and gen fonts, adding the male and female symbols to Knuth's gen font, and so avoiding loading two fonts when you need only genealogical symbols. The font is distributed as Metafont source.

This is a music-related package which is focused on notation from the twelve-tone system, also called dodecaphonism. It provides LaTeX algorithms that produce typical dodecaphonic notation based off a musical series, or row sequence, of variable length.

This small package aims to provide two simple commands and many options to easily write linear operators as they appear in many-body physics, quantum theory, and linear algebra, in any of the ways commonly in use.

This package provides a language support package for Omega and Lambda. This replaces the original Omega package for use with Lambda, and provides extra facilities (including Babel-like language switching, which eases porting of LaTeX documents to Lambda).

The bundledoc package is a post-processor for the snapshot package that bundles together all the classes, packages and files needed to build a given LaTeX document. It reads the .dep file that snapshot produces, finds each of the files mentioned therein, and archives them into a single .tar.gz (or .zip, or whatever) file, suitable for moving across systems, transmitting to a colleague, etc. A script, arlatex, provides an alternative archiving mechanism, creating a single LaTeX file that contains all of the ancillary files of a LaTeX document, together with the document itself, using the filecontents* environment.

This MetaPost package allows to draw Kiviat diagrams (or radar chart, web chart, spider chart, etc.).

SJTUTeX aims to establish a simple and easy-to-use collection of document classes for Shanghai Jiao Tong University, including the thesis document class sjtuthesis, as well as the regular document classes sjtuarticle and sjtureport.

This package supports typesetting CJK documents. It allows users to specify the two ratios between the leading and the font size of the body text and the footnote text. For CJK typesetting, these ratios usually range from 1.5 to 1.67. This package is also capable of restoring the math leading to that of the Latin text (usually 1.2 times the font size).

If your LaTeX document is version-controlled with Git, you might encounter situations, where you want to include some information of your Git repository into your LaTeX document, e.g., to keep track on who gave you feedback on which version of your document. This Git information can be included on every page by a watermark or (for custom needs) via provided variables.

This package enables the usage of classes as packages. It was originally designed for the l3doc class, which is employed for documenting LaTeX code with numerous useful features. However, employing the l3doc class as a package is not convenient when using the developing class as the style for the document. Therefore, this package provides a simple interface for utilizing classes as packages.

The class was developed for use by students writing legal essays (juristische Hausarbeit) at German Universities. It is based on jurabook and jurabib and makes it easy for LaTeX beginners to get a correct and nicely formatted paper.

This package implements a LaTeX command that converts an amsrefs bibliographical database (.ltb) to a BibTeX bibliographical database (.bib). ltb2bib is the reverse of the amsxport option in amsrefs.

This module provides the latin style that can be set using \DTMsetstyle provided by datetime2.sty. This package is currently unmaintained.

This package provides bibliographic style references in style of Australian Journal of Linguistics.
