Since PDF 1.5 portions of a page can be marked for better accessibility support. For example, replacement texts or expansions of abbreviations can be provided. This package starts with providing a minimal low-level interface for programmers; its status is experimental.

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 extends the \hhline command with a !{...} token, which allows creating lines with arbitrary LaTeX commands.

This package provides a Perl/Tk-based GUI for easy access to package documentation for TeX on Unix platforms; the databases it uses are based on the texmf/doc subtrees of teTeX, but database files for local configurations with modified/extended directories can be derived from them. Note that texdoctk is not a viewer itself, but an interface for finding documentation files and opening them with the appropriate viewer; so it relies on appropriate programs to be installed on the system. However, the choice of these programs can be configured by the sysadmin or user.

This package provides the geradwp class, a class based on article and compatible with LaTeX. With this class, researchers at GERAD will be able to write their working paper while complying to all the presentation standards required by the Cahiers du GERAD series.

This is a BibTeX style file for papers in economics. It provides the following features: author-year type citation reference style used in economics papers highly customizable use of certified random order, as proposed by Ray Robson (2018)

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

The package defines an exercise environment which numbers every exercise, and a command \get to extract a collection whose argument is a comma-separated set of exercise index numbers. While the package was designed for teachers constructing tables of exercises, it plainly has more general application.

This package makes available the most commonly used symbols in writing about music in a way that can be used with pdfLaTeX and looks consistent and attractive. It includes accidentals, meters, and notes of different rhythmic values. The package builds on the approach used in the harmony package, where the symbols are taken from the MusiXTeX fonts. But it provides a larger range of symbols and a more flexible, user-friendly interface.

This package lets you customize the appearance of the vertical rule that appears between columns of multicolumn text. It is primarily intended to work with the multicol package, hence its name, but also supports the twocolumn option and \twocolumn macro provided by the standard classes (and related classes such as the KOMA-Script equivalents).

This package is an extension to lineno, replacing that package's line numbers with bars to the left or right of the text.

This is an experimental package which implements an environment, blockarray, that may be used in the same way as the array or tabular environments of standard LaTeX, or their extended versions defined in array. If used in math-mode, blockarray acts like array, otherwise it acts like tabular. The package implements a new method of defining column types, and also block and block* environments, for specifying sub-arrays of the main array. What's more, the \footnote command works inside a blockarray.

This package is designed to help mathematicians publishing papers in the area of recursion theory (aka Computability Theory) easily use standard notation. This includes easy commands to denote Turing reductions, Turing functionals, c.e.: sets, stagewise computations, forcing and syntactic classes.

The command \nth<number> generates English ordinal numbers of the form 1st, 2nd, 3rd, 4th, etc. LaTeX package options may specify that the ordinal mark be superscripted, and that negative numbers may be treated; Plain TeX users have no access to package options, so need to redefine macros for these changes.

This LaTeX2e package enables the embedding of MetaPost figures within LaTeX documents. The package automatically collects the embedded definitions and figures in a .mp file, adds an appropriate LaTeX document structure, and compiles it to .mps files. It also allows for various configuration options to manage the generation of files and compilation.

The package is an unofficial alternative to the package provided with the Asymptote distribution, for including pictures within a LaTeX source file. While it does not duplicate all the features of the official package, this package is more user-friendly in several ways. Most notably, Asymptote errors are repackaged as LaTeX errors, making debugging less of a pain. It also has a more robust mechanism for identifying unchanged pictures that need not be recompiled.

This package defines a few LaTeX commands that may be useful when you proofread a LaTeX document. They allow you to easily highlight text and add comments in the margin. Vim escape sequences are provided for inserting or removing these LaTeX commands in the source. Options are provided for displaying the document with extra line spacing, and for displaying it in either corrected or uncorrected state, both without margin notes.

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 bundle provides a class examdesign. The class provides several features useful for designing tests or question sets: it allows for explicit markup of questions and answers; the class will, at the user's request, automatically generate answer keys; multiple versions of the same test can be generated automatically, with the ordering of questions within each section randomly permuted so as to minimize cheating; the generated answer keys can be constructed either with or without the questions included; environments are provided to assist in constructing the most common types of test question: matching, true/false, multiple-choice, fill-in-the-blank, and short answer/essay questions.

The package defines macros using SS to type Greek letters so that the user may type SSa to get the effect of $\alpha$. However, it takes care only of letters which have a macro name like \alpha or \Omega.

The package characterises and defines the author's B1 encoding for use with LaTeX when typesetting things using his Bookhands fonts.

Garamond Libre is an old-style font family. It is a true Garamond, i.e., it is based off the designs of 16th-century French engraver Claude Garamond (also spelled Garamont). The Roman design is Garamond's; the italics are from a design by Robert Granjon. The upright Greek font is after a design by Firmin Didot; the italic Greek font is after a design by Alexander Wilson. The font family includes support for Latin, Greek (monotonic and polytonic) and Cyrillic scripts, as well as small capitals, old-style figures, superior and inferior figures, historical ligatures, Byzantine musical symbols, the IPA and swash capitals.

This package provides commands to convert a date into a number and vice versa. Additionally there are commands for incrementing and decrementing a date. Leap years and the Gregorian calendar reform are considered.

This package loads url by default and defines possible URL breaks for all alphanumerical characters, as well as =, /, ., :, *, -, ~, and ". All arguments which are valid for url can be used and will be passed on to this package.
