The package deals with EAN barcodes; Metafont sources for fonts are provided, and a set of examples; for some codes, a small Perl script is needed.

This LaTeX package can output annotation symbols enclosed in square brackets and marked with an asterisk.

This template helps the author design books published on Amazon under the ``Y.B.'' brand.

Boisik is a serif font set (inspired by the Baskerville typeface), written in Metafont. The set comprises roman and italic text fonts and maths fonts. LaTeX support is offered for use with OT1, IL2 and OM* encodings.

This package provides horizontally and vertically split elliptical (pairs of) nodes in TikZ. The package name derives from the fact that split ellipses of this type are used to represent Single-World Intervention Graph (SWIG) models which are used in counterfactual causal inference.

This package helps spacing out the letters of text; the command is \letterspace<\hbox modifier>{<text>}: the text is placed in an \hbox of the specified size, and space is inserted between each glyph to make the text fit the box. Note that letterspacing is not ordinarily considered acceptable in modern typesetting of English.

This experimental package can read and parse text tables delimited by user-defined tokens (e.g., Tab). It can be used for serial letters and the like, making it easier to export the data file from MS-Excel/MS-Word

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.

The original amscd package provides a CD environment that emulates the commutative diagram capabilities of AMS-TeX version 2.x. This means that only simple rectangular diagrams are supported, with no diagonal arrows or more exotic features. This enhancement package implements double, dashed, and bidirectional arrows (left-right and up-down), and color attributes for arrows and their annotations. The restriction to rectangular geometry remains. This nevertheless allows the drawing of a much broader class of commutative diagrams and alike.

This package provides the preferred document class for papers to be submitted to Quantum --- the open journal of quantum science. It is based on the article document class.

As a service to authors, the document class comes with a predefined bibliography style quantum.bst that is optimized to be used with the quantumarticle document class. Additionally, the quantumview document class is provided, which can be used as a proxy to typeset the HTML-only editorial pieces in Quantum Views.

The quantumarticle document class also offers an option to remove the Quantum-related branding. In that way, users can use it for their notes as well.

This package can only be used with LuaLaTeX or XeLaTeX. It does the font setting for the OpenType font TeX Gyre Heros. The condensed versions of the fonts are also supported. The missing typefaces for slanted text are defined.

Garamond-Math is an OpenType math font matching EB Garamond (Octavio Pardo) and EB Garamond (Georg Mayr-Duffner). Many mathematical symbols are derived from other fonts, others are made from scratch.

The module typesets messenger chats on a smartphone, depicting a simplified interface.

The use of formats helps to speed up compilations: packages which have been dumped in the format are loaded at very high speed. This is useful when a document loads many packages.

The package checks for floats that are placed too far from their origin.

This class for typesetting journal articles is accepted for submitted articles both in Elsevier's electronic submission system and elsewhere.

The built-in determination of the bounding box in TikZ is not entirely accurate. This is because, for Bezier curves, it is the smallest box that contains all control points, which is in general larger than the box that just contains the curve. This library determines the exact bounding box of the curve.

The package implements the sectioning commands fully compatible with the standard classes. This is intended, e.g., to make the KOMA-Script classes work with packages like titlesec, which depend on the implementation of these commands.

The bundle provides boxes and picture macros with Japanese vertical writing support. It uses only native picture macros and fonts for drawing boxes and is thus driver independent.

The package provides a way to highlight formulas and formula parts in both documents and presentations, us TikZ.

The file defines a macro \compare, which takes two arguments; the macro expands to -1, 0, 1, according as the first argument is less than, equal to, or greater than the second argument. Sorting is alphabetic, using ASCII collating order.

This package defines the environments exercise and solution. The layout of these environments can be customized. The -- optional -- points in the exercises can be added automatically. The package also permits hiding the solutions.

The package recursively draws trees: each subtree is defined in a bundle environment, with a set of leaves described by \chunk macros. A chunk may have a bundle environment inside it.

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.
