This package defines commands \counterwithin (which sets up a counter to be reset when another is incremented) and \counterwithout (which unsets such a relationship).

The package supports those within the quantum information community who typeset quantum circuits, using xy-pic package, offering macros designed to help users generate circuits.

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.

The package suppresses typographic ligatures selectively, i.e., based on predefined search patterns. The search patterns focus on ligatures deemed inappropriate because they span morpheme boundaries.

This tiny package allows easy manipulation of the headers and footers on pages left blank by \cleardoublepage. By default, LaTeX has no easy facilities for this.

The longfbox package provides framed boxes that can be customized using standard CSS attributes. It was written to support precise rendering of Madoko documents in LaTeX.

MetaPost uses a language based on that of Metafont to produce precise technical illustrations. Its output is scalable PostScript or SVG, rather than the bitmaps Metafont creates.

This package draws a grid on every page of the document; the grid divides the page into columns, and may be used for fixing measurements of layout.

This LaTeX package provides an interface to define and evaluate key-based replacement rules. It can be used to parse the argument specification of a document command.

This package provides control over section numbering (without recourse to starred sectional commands) and the entries in the table of contents on a section by section basis.

This package exposes spacing parameters for various TeX logos to the end user, to optimise the logos for different fonts. It is written especially for XeLaTeX users.

The class and its BibTeX style enable authors to produce officially-correct output for the IEEE transactions, journals and conferences.

This package provides an interface to dummy text in Chinese language, which will be useful for testing Chinese documents. UTF-8, GBK and Big5 encodings are supported.

This package provides the means in order to lay-out gamebooks with LaTeX. A simple gamebook example is included with the package, and acts as a tutorial.

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.

The package is for printing two pages on a single (landscape) A4 page. Page numbers appear on the included pages, and not on the landscape container page.

The varwidth environment is superficially similar to minipage, but the specified width is just a maximum value -- the box may get a narrower natural width.

The package extends the hyperref functionality for creating interactive forms to allow adding Barcode form fields supported by some modern PDF readers. Currently, only pdfTeX is supported.

The package computes the number of sheets of paper used by, and hence the mass of a document. This is useful (for example) when calculating postal charges.

This MetaPost package provides macros to typeset text along a free path with the help of LaTeX, thereby preserving kerning and allowing for 8-bit input (accented characters).

This package provides an environment that has its own line numbers or markers and can be well distinguished from the main text, for writing your ideas or annotations.

This package provides a package to typeset syntactic trees such as those used in Chomsky's generative grammar, based on a description of the structure of the tree.

This package implements a new bookmark (outline) organization for the hyperref package. Bookmark properties such as style and color. Other action types are available (URI, GoToR, Named).

The package offers a number of notational conventions to be used in applied and theoretical papers in statistics which are currently lacking in the popular amsmath package.
