This package provides macros to use upright greek letters as text symbols.

The package defines commands to iterate functions of a single variable, find fixed points, zeros and extrema of such functions, and calculate the terms of recurrence relations.

These packages are either mandated by the core LaTeX team, or very widely used and strongly recommended in practice.

The macros include: format for question-and-answer; comments on answers; lengthier explanations of answers; citations. The formatting of all the macros is highly (and simply) customizable.

This package provides the command \marginnote that may be used instead of \marginpar at almost every place where \marginpar cannot be used, e.g., inside floats, footnotes, or in frames made with the framed package.

The package defines a \label- and \ref-like commands for compound numbers.

This package permits drawing program charts in the style of the Scratch project. This package is obsolete. From now on, Scratch is now version 3 with a new design. Use the scratch3 package to draw blocks with the new design.

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

This package provides some macros for right-to-left typesetting. It uses by default the Arabic fonts Scheherazade and ALM fixed, the only monospaced Arabic font. The package only works with LuaLaTeX or XeLaTeX.

This package provides an Italian translation for some old amsmath documents. The documents are: diffs-m.txt of December 1999, and amsmath.faq of March 2000.

The idxlayout package offers a key-value interface to configure index layout parameters, e.g. allowing for three-column indexes or for parent items and their affiliated subitems being typeset as a single paragraph. The package is responsive to the index-related options and commands of the KOMA-Script and memoir classes.

This package provides several extensions to fancyvrb, including automatic line breaking and improved math mode.

PostScript lacks a lot of basic operators such as tan, acos, asin, cosh, sinh, tanh, acosh, asinh, atanh, exp (with e base). Also (oddly) cos and sin use arguments in degrees. Pst-math provides all those operators in a header file pst-math.pro with wrappers pst-math.sty and pst-math.tex. In addition, sinc, gauss, gammaln and bessel are implemented (only partially for the latter). The package is designed essentially to work with pst-plot but can be used in whatever PS code. The package also provides a routine SIMPSON for numerical integration and a solver of linear equation systems.

The package aims to solve the error No room for a new \write, which occurs when the user, or when the user's packages have allocated too many streams using \newwrite (TeX has a fixed maximum number --- 16 --- of such streams built-in to its code). The package hooks into TeX primitive commands associated with writing to files; it should be loaded near the beginning of the sequence of loading packages for a document.

This is the Babel style for Malay.

The class typesets papers for IMS (Iranian Mathematical Society) conference proceedings. The class uses the XePersian package.

This MetaPost package allows to draw binary Huffman trees from two arrays: an array of strings, and an array of weights (numeric). It is based on the METAOBJ package which provides many tools for building trees in general.

This package enables the use of small capitals in different font shapes, e.g., slanted or bold slanted for all fonts that provide appropriate font shapes.

The package provides PDF color spaces. Currently, only spot colors and overprinting are supported.

The package simplifies typesetting of simple crystallographic group-subgroup-schemes in the Barnighausen formalism. It defines a new environment stammbaum, wherein all elements of the scheme are defined. Afterwards all necessary dimensions are calculated and the scheme is drawn. Currently two steps of symmetry reduction are supported.

The package provides files offering interfaces to 33 publicly available fonts (or collections of fonts from the same foundry); each is available in a .mkii and a .mkiv version.

This package provides a French translation of the documentation of array.

This package provides an environment to switch a section of code on or off. The code may be placed anywhere in the file (it is not limited to the document or the preamble). The motivation for this package was to have commands which allow preselection based on whether sections of code in a preamble of a template are executed.

This package provides commands \alphalph and \AlphAlph. They are like \number but the expansion consists of lowercase and uppercase letters respectively (1 to a, 26 to z, 27 to aa, 52 to zz, 53 to ba, 702 to zz, 703 to aaa, etc.). Alphalph's commands can be used as a replacement for LaTeX's \@alph and \@Alph macros.
