The package lets you shade or colour the cells in the alignment environments such as \halign and LaTeX's tabular and array environments. The colortbl package is to be preferred today with LaTeX (it assures compatibility with the longtable package, which is no longer true with colortab); another modern option is the table-colouring option of the xcolor. However, colortab remains an adequate solution for use with Plain TeX.

The package is a specialized tool built on top of PGF/TikZ for drawing spectral sequences. It provides a powerful, concise syntax for specifying the data of a spectral sequence, and then allows the user to print various pages of spectral sequences, automatically choosing which subset of the classes, differentials, and structure lines to display on each page. It also handles most of the details of the layout. At the same time, it is extremely flexible. spectralsequences is closely integrated with TikZ to ensure that users can take advantage of as much as possible of its expressive power. It is possible to turn off most of the automated layout features and draw replacements using TikZ commands. The package also provides a carefully designed error reporting system intended to ensure that it is as clear as possible what is going wrong.

This package provides some macros to write documentation of LaTeX packages in a tutorial style.

This is a collection of TeX formats, i.e., large-scale macro packages designed to be dumped into .fmt files --- excluding the most common ones, such as LaTeX and ConTeXt, which have their own package(s). It also includes the Aleph engine and related Omega formats and packages, and the HiTeX engine and related.

This package works around the LaTeX bug that marginpars will sometimes come out at the wrong margin.

Product integrals are to products, as integrals are to sums. They have been around for more than a hundred years, they have not become part of the standard mathematician's toolbox, possibly because no-one invented the right mathematical symbol for them. The authors have remedied that situation by proposing the symbol and providing this font.

Patgen takes a list of hyphenated words and generates a set of patterns that can be used by the TeX 82 hyphenation algorithm.

The purpose of this package is to provide the periodic table of elements in a simple way. It relies on PGF/TikZ to offer a full or partial periodic table with a variety of options and displaying the desired data for all the 118 elements.

This package provides a program that converts LaTeX source to Braille/Nemeth. It supports the Greek language, which is only Braille level 1, but also English at level 1. Simple pictures in PSTricks are also supported in order to produce tactile graphics with specialized equipment. Note that embossing will need LibreOffice and odt2braille as this project does not deal with embossers drivers.

This package provides the quickreaction environment and the \quickarrow command to simplify the typesetting of chemical reactions.

This is a translation of the documentation provided with ntheorem.

The package defines a mechanism for specifying connected trees that uses a tabular environment to generate node positions. The package uses PostScript code, loaded by Dvips, so output can only be generated by use of Dvips.

The package lingmacros.sty defines a few macros for linguists: \enumsentence for enumerating sentence examples, simple tabular-based non-connected tree macros, and gloss macros.

The cmtiup fonts address a problem with the appearance of punctuation in italic text in mathematical documents. To achieve this, all punctuation characters are upright, and kerning between letters and punctuation is adjusted to allow for the italic correction. The fonts are implemented as a set of .vf files; a package for support in LaTeX is provided.

These files are regarded as basic for any TeX system, covering plain TeX macros, Computer Modern fonts, and configuration for common drivers; no LaTeX.

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 font family is a modification of cm-unicode fonts, with Arabic support.

The tkz-euclide package is a set of files designed to give math teachers and students easy access to the programming of Euclidean geometry with TikZ.

The package provides a map for use with Jonathan Kew's TECkit, to translate Devanagari (encoded according to the Harvard/Kyoto convention) to Unicode (range 0900-097F).

This package provides a font based on Computer Modern Roman useful for typesetting the mathematical symbols for the natural numbers, whole numbers, rational numbers, real numbers and complex numbers; coverage includes all Roman capital letters, 1, h and k. The font is available both as Metafont source and in Adobe Type 1 format, and LaTeX macros for its use are provided.

The package provides a diagram environment. This allows the LaTeX user to easily create complex commutative diagrams, by placing formula nodes on a conceptual grid and attaching arrows to them.

The package adds to PSTricks the ability to draw 3-dimensional views of the five Platonic solids.

Some engineers need underlined or twice underlined variables for which the usual \underline is too long. This package provides a generic command for creating underlines of various sizes and types.

The set of the Japanese logical fonts (JFMs) that are used as standard fonts in pTeX and upTeX contains both Unicode JFMs and non-Unicode JFMs. This bundle provides an alternative set of non-Unicode JFMs that are tied to the virtual fonts (VFs) that refer to the glyphs in the Unicode JFMs. Moreover it provides a LaTeX package that redefines the NFSS settings of the Japanese fonts of (u)pLaTeX so that the new set of non-Unicode JFMs will be employed. As a whole, this bundle allows users to dispense with the mapping setup on non-Unicode JFMs. Such a setup is useful in particular when users want to use OpenType fonts (such as Source Han Serif) that have a glyph encoding different from Adobe-Japan1, because mapping setups from non-Unicode JFMs to such physical fonts are difficult to prepare.

The package is used to change the format of \today’s date, including the weekday, e.g., Saturday, 26 June 2008, the UK format, which is preferred in many parts of the world, as distinct from that which is used in \maketitle of the article class, June 26, 2008, the US format.
