The package is designed to localise any document class or package. This should be very useful for end-users who could obtain messages in their own preferred language.

This package provides a document class for writing articles to the Journal of Electrical Bioimpedance.

The package provides a kana parser for LuaTeX. It is a set of four macros that handle transliteration of text: from hiragana and katakana to Latin from Latin and katakana to hiragana from Latin and hiragana to katakana It can be used to write kana directly using only the ASCII character set or for education purposes. The package has support for obsolete and rarely used syllables, some only accessible via the provided toggle macro.

This package provides EAN-8 and EAN-13 forms.

The package computes and draws 2D Delaunay triangulation. The algorithm is written with Lua, and depending upon the choice of the engine, the drawing is done by MetaPost (with luamplib) or by TikZ. The Delaunay triangulation algorithm is the Bowyer and Watson algorithm. Several macros are provided to draw the global mesh, the set of points, or a particular step of the algorithm.

This package offers commands to use and switch between chess fonts. It uses the LaTeX font selection scheme (nfss). The package doesn't parse, format and print PGN input like e.g., the packages skak or texmate; the aim of the package is to offer writers of chess packages a bundle of commands for fonts, so that they don't have to implement all these commands for themselves. A normal user can use the package to print e.g,. single chess symbols and simple diagrams.

This package eases standard conforming typesetting of Japanese, for XeLaTeX.

This LaTeX2e package makes it possible to add timing marks to lecture notes in order to help managing the time available for presenting a given section of the document. It also provides tools to record and estimate the progress throughout the course.

The font (defined in Metafont) defines a single character, a black solid skull. A package is supplied to make this character available as a symbol in maths mode.

The package provides Bidi-aware page grid in background. It is based on pagegrid.

Simply changing \parskip and \parindent leaves a layout that is untidy; this package (though it is no substitute for a properly designed class) helps alleviate this untidiness.

The package provides the means to typeset Creative Commons icons, in documents licensed under CC licences. A font (in Adobe Type 1 format) and LaTeX support macros are provided.

This is a pure Lua library, which provides functions and objects for the computation of physical quantities. The package provides units of the SI and the imperial system. In order to display the numbers with measurement uncertainties, the package is able to perform Gaussian error propagation.

Paper submissions to journals are usually accompanied by a cover letter. This package provides a LaTeX class and a template for such a cover letter with the following main features:

• minimalistic design,

• custom image,

• pre-defined commands for journal name, author, date, etc.

• many macros contained in this package speed up the process of preparing the necessary ingredients for the cover letter;

• macros for recommending up to three reviewers and editors;

• ORCID logo and link to the submitting author's ORCID page;

• controls for adding a ``conflict of interest'' statement and declaration;

• custom greeting;

• predefined valedictions for different types of submissions.

The package provides an environment for syntax highlighting source code in LaTeX documents. The highlighted source code output is formatted via Pygments library of the Python language.

This package provides a collection of packages containing: accenti, dblfont, envmath, evenpage, graphfig, mathcmd, quotes, and sobolev.

This package allows the user to produce Braille documents on paper for the blind without knowing Braille. Python scripts grade1.py and grade2.py convert ordinary text to grade 1 and 2 Braille tags; then, the LaTeX package takes the tags and prints out corresponding Braille symbols.

Latin Modern Math is a maths companion for the Latin Modern family of fonts, in OpenType format. For use with LuaLaTeX or XeLaTeX, support is available from the unicode-math package.

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 provides support for rendering UML diagrams using the syntax and tools of PlantUML. The PlantUML syntax is very short and thus enables quickly specifying UML diagrams. Using dot, PlantUML layouts the diagrams.

Knuth designed his original fonts with tabular figures (figures whose width is uniform); this makes some layout problems rather simple. In more recent times, fonts (such as Minion Pro), which offer proportionally spaced figures, are increasingly being used. The package provides mechanisms whereby such proportional figures may still be aligned in tabular style (for example, in the table of contents).

This package provides a command for the LaTeX programmer for testing whether an argument is empty.

The package provides language drivers for the listings package for several languages not included in that package: BUGS, JAGS, and Stan.

This package provides the source of the examples printed in The LaTeX Companion book, together with necessary supporting files.
