This package provides a tool to make the structure of tagged PDF files visible. It parses a PDF file and extracts most tagging related information to turn it into either a visual tree structure or an XML document representing the tags. The package is released together with a collection of schema which can be used to check that the resulting XML structure follows specified rules.

The package supports drawing proof trees of the kind often used in introductory logic classes, especially those aimed at students without strong mathemtical backgrounds. Hodges (1991) is one example of a text which uses this system. When teaching such a system it is especially useful to annotate the tree with line numbers, justifications and explanations of branch closures. The package provides a single environment, prooftree, and a variety of tools for annotating, customising and highlighting such trees. A cross-referencing system is provided for trees which cite line numbers in justifications for proof lines or branch closures.

This package provides a very short snippet that sets the footnotes to be conformant with the Chicago style, so the footnotes at the bottom of the page are now marked with a full-sized number, rather than with a superscript number.

The bundle provides files for building formats to read input in Polish encodings.

This package provides TeX support (from CJK) for the Garuda font.

The main goal of this package is to provide means for typesetting checklists in a way that stipulates users to explicitly distinguish checklists for goals, for tasks, for artifacts, and for milestones --- i.e., the type of checklist entries. The intention behind this is that a user of the package is coerced to think about what kind of entries he/she adds to the checklist. This shall yield a clearer result and, in the long run, help with training to distinguish entries of different types.

The package defines multiple level lists within one list-like environment, with the help of the \iitem, \iiitem, ... macros.

This document class provides both Arabic and English support for TeX and LaTeX. Input may be in ASCII transliteration or other encodings (including UTF-8), and output may be Arabic, Hebrew, or any of several languages that use the Arabic script, as can be specified by the Polyglossia package. The Arabic font is presently available in any Arabic fonts style. In order to use Amiri font style, the user needs to install the amiri package. This document class runs with the XeTeX engine. PDF files generated using this class can be searched, and text can be copied from them and pasted elsewhere.

The package supports drawing of very thick lines and curves in PSTricks, with various fillings for the body of the lines.

tikzcodeblocks is a LaTeX package for typesetting blockwise graphic programming languages like Scratch, NEPO or PXT.

The package provides additional features for the LaTeX description environment, including adjustable left margin. The package also allows the user to break a list (for example, to interpose a comment) without affecting the structure of the list (this works for itemize and eumerate lists and numbered lists remain in sequence).

This package provides an unofficial BibTeX style for authors of the Institute of Electrical Engineers of Japan (IEEJ) transactions journals and conferences.

This style file is designed for converting Japanese half-width characters to full-width characters beautifully. This is useful when alphabet characters don't render properly in a Japanese font.

This package helps you keep track of all the labels you define, by putting the name of new labels into the margin whenever the \label command is used. The package allows you to do the same thing for other commands. The only one for which this is obviously useful is the \cite command, but it's easy to do it for others, such as the \ref or \begin commands.

This package provides a fairly light-weight solution for annotating LaTeX source code with color to show additions/changes, replacements, deletions, and comments. This is particularly useful when a document is being edited by multiple authors. Two package options allow the quick suppression of all colorful edits and comments, and showing text whose deletion was proposed.

This LaTeX3 package based on l3draw provides macros and an environment for Chinese chess manual writing.

The package is designed to produce from BibTeX or BibLaTeX bibliographical databases the different indices of authors and works cited which are called indices locorum citatorum. It relies on a specific \icite command and can operate with either BibTeX or BibLaTeX.

The package allows the user to define shorthand aliases for single Unicode characters, and also provides support for such aliases in RTL-text. The package requires an TeX-alike system that uses Unicode input in a native way: current examples are XeTeX and LuaTeX.

The package offers a simple notation for pretty complex tables (to Michael J.: Ferguson's credit). With PostScript, the package allows shaded/coloured tables, diagonal rules, etc. The package is supposed to work with both Plain and LaTeX. An AWK converter from ASCII semigraphic tables to TAP notation is included.

The package is designed for lecturers who have to generate new problem sheets for their students on a regular basis by randomly selecting a specified number of problems defined in another file. The package allows you easily to generate a new problem sheet that is different from the previous year, thus alleviating the temptation of students to seek out the previous year's students and checking out their answers. The solutions to the problems can be defined along with the problem, making it easy to generate the solution sheet from the same source code; problems may be reused within a document, so that solutions may appear in a different section of the same document as the problems they cover.

The package defines means of drawing frames around boxes, using dingbat fonts. Some (Metafont) font sources are included; the fonts are available separately in Type 1 format.

The package provides translations and various formats for the use of bibleref in German documents. The German naming of the Bible books complies with the Loccumer Richtlinien (Locum guidelines). In addition, the Vulgate (Latin Bible) is supported.

This collection provides support for Arabic and Persian.

In the year 2010, Randall Munroe on posted a really funny and nice article on XKCD. He made a very curious experiment: showing colors to a lot of people and asking to name each one. Afterward, he processed the data and sorted the names for each color by popularity --- that means, how many people gave the same name to the same color. This package makes the collected color names usable with LaTeX.
