The package ltxnew provides \new, \renew and \provide prefixes for checking definitions. It is designed to work with e-TeX distributions of LaTeX and relies on the LaTeX internal macro \@ifdefinable. Local allocation of counters, dimensions, skips, muskips, boxes, tokens and marks are provided by the etex package. \new and \renew as well as \provide may be used for all kind of control sequences.

With the help of this LaTeX package, a context-free grammar (CFG) may be rendered in a plain-text mode using a simplified Extended Backus-Naur Form (EBNF) notation.

This class implements rules to typeset Brazilian legal texts. Its purpose is to be an easy-to-use implementation for the end-user.

The package draws Bao diagrams in LaTeX. The package is a development of psgo, and uses PSTricks to draw the diagrams.

Old Standard is designed to reproduce the actual printing style of the early 20th century, reviving a specific type of Modern (classicist) style of serif typefaces, very commonly used in various editions of the late 19th and early 20th century.

The font supports typesetting of Old and Middle English, Old Icelandic, Cyrillic (with historical characters, extensions for Old Slavonic and localised forms), Gothic transliterations, critical editions of Classical Greek and Latin, and many more.

This package provides LaTeX format files and man pages along with several packages that are considered as part of the LaTeX kernel.

This package contains the supporting documentation, slides, exercise files, and templates for an introductory LaTeX course (in French) prepared for Universite Laval, Quebec, Canada.

This bundle provides four BibLaTeX styles that implement (many of) the stipulations and examples provided by the 2014 New Hart's Rules and the 2002 Oxford Guide to Style:

• oxnotes is a style similar to the standard verbose, intended for use with footnotes;

• oxnum is a style similar to the standard numeric, intended for use with numeric in-text citations;

• oxalph is a style similar to the standard alphabetic, intended for use with alphabetic in-text citations;

• oxyear is a style similar to the standard author-year, intended for use with parenthetical in-text citations.

The bundle provides support for a wide variety of content types, including manuscripts, audiovisual resources, social media and legal references.

This package provides some macros to display alert messages (information, errors, warnings and success messages).

This package provides a package providing commands for continuation captions, unnumbered captions, and also a non-specific legend heading for any environment. Methods are also provided to define captions for use outside float (e.g., figure and table) environments, and to define new float environments and lists of floats. Tools are provided for specifying your own captioning styles.

The bundle provides a collection of BibTeX style files to turn an address database stored in the .bib format into files suitable for printing as address books or included into letter classes like akletter or scrletter2. The data may be sorted either by name or birthday and output provides files in various formats for address books or time planners.

This package uses both tracklang and texosquery to look up the locale information from the operating system and provide commands that can access locale-dependent information, such as the currency symbol and decimal separator.

The yhmath bundle contains fonts (in Metafont and type 1 format) and a LaTeX package for using them.

Correctly sizing delimiters is very difficult, particularly in well-architected documents: a correctly engineered mathematical document will include macros for all operations, and these macros necessarily will include delimiters (such as parentheses). However, the correct size for the delimiter cannot be chosen ahead of time, because it will depend on the arguments; two options are available: Provide optional arguments to each notation macro for choosing delimiter sizes. This is nearly intractable to do in practice. Ignore delimiter sizes. With jmsdelim we offer an alternative: the correct delimiter sizes can be set at the leaf nodes of a mathematical expression, and magically bubble upward through the delimiters.

This package provides commands to typeset proof trees in the style of sequent calculus and related systems.

The package provides a LISP interpreter written using TeX macros; it is provided as a LaTeX package. The interpreter static scoping, dynamic typing, and eager evaluation.

The KorigamiK class is used for typesetting documents for university or school projects and lab reports. It is based on the article class with modifications to allow for more flexible front-matter among other small changes.

This package provides a Unicode compatible index program for LaTeX.

The package provides a macro for drawing trees with TikZ using the easy syntax of Alexis Dimitriadis Qtree. It improves on TikZ's standard tree-drawing facility by laying out tree nodes without collisions; it improves on Qtree by adding lots of features from TikZ (for example, edge labels, arrows between nodes); and it improves on pst-qtree in being usable with pdfTeX and XeTeX.

This package provides advanced facilities for inline and display quotations. It is designed for a wide range of tasks ranging from the most simple applications to the more complex demands of formal quotations. The facilities include commands, environments, and user-definable smart quotes which dynamically adjust to their context. Quotation marks are switched automatically if quotations are nested and they can be adjusted to the current language if the babel package is available. There are additional facilities designed to cope with the more specific demands of academic writing, especially in the humanities and the social sciences. All quote styles as well as the optional active quotes are freely configurable.

The package redefines the thebibliography environment to place the citation key into the margin.

Algorithm2e is an environment for writing algorithms. An algorithm becomes a floating object (like figure, table, etc.). The package provides macros that allow you to create different keywords, and a set of predefined key words is provided; you can change the typography of the keywords. The package allows vertical lines delimiting a block of instructions in an algorithm, and defines different sorts of algorithms such as Procedure or Function; the name of these functions may be reused in the text or in other algorithms.

This package provides a LaTeX package for using compound numbers in chemistry documents. It works like \cite and the \thebibliography, using \fcite and \theffbibliography instead. It allows compound names in documents to be numbered and does not affect the normal citation routines.

The diadia package allows you to keep a diabetes diary. Usually, this means keeping record of certain medical values like blood sugar, blood pressure, pulse or weight. It might also include other medical, pharmaceutical or nutritional data (HbA1c, insulin doses, carbohydrate units).

The diadia package supports all of this plus more --- simply by adding more columns to the data file! It is able to evaluate the data file and typesets formatted tables and derived plots. Furthermore, it supports medication charts and info boxes.
