This package provides a parallel environment which allows two potentially different texts to be typeset in two columns, while maintaining alignment. The two columns may be on the same page, or on facing pages. This arrangement of text is commonly used when typesetting translations, but it can have value when comparing any two texts.

This LaTeX package makes it possible to simulate interference patterns occurring on a screen if monochromatic light is diffracted at regular structures of slits.

The fonts are derived from the Computer Modern Mathematics fonts and from Knuth's Concrete Roman fonts; they are distributed as Metafont source. LaTeX support is offered by the concmath package.

This package fetches the source for all TeX Live programs provided by the TeX Live repository. It is meant to be used as a source-only package; it should not be installed in a profile.

Awesome Box is all about drawing admonition blocks around text to inform or alert readers about something particular. The specific aim of this package is to use FontAwesome icons to ease the illustration of these blocks.

The schule bundle was built to provide packages and commands that could be useful for documents in German schools. At the moment, its main focus lies on documents for informatics as a school subject. An extension for physics is currently in progress.

For the time being, the whole package splits up into individual packages for informatics (including syntax diagrams, Nassi-Shneiderman diagrams, sequence diagrams, object diagrams, and class diagrams) as well as classes for written exams (tests, quizzes, teaching observations, information sheets, worksheets, and answer keys).

This package provides a package for typesetting Young-Tableaux, mathematical symbols for the representations of groups, providing two macros, \yng(1) and \young(1) to generate the whole Young-Tableau.

The package comprises reference documentation for XeTeX detailing its extended features.

The package provides commands for typesetting a CV or resume. It provides commands for general-purpose headings, entries, and item/description pairs, as well as more specific commands for formatting sections, with explicit inclusion of school, degree, employer, job, conference, and publications entries. It tends to produce a somewhat long and quite detailed document but may also be suitable to support a shorter resume.

The package provides a parser \poldef of algebraic polynomial expressions. Once defined, a polynomial is usable by its name either as a numerical function in \xintexpr or \xinteval, or for additional polynomial definitions, or as argument to the package macros. The localization of real roots to arbitrary precision as well as the determination of all rational roots is implemented via such macros.

This package provides an implementation of the Universal by Herbert Bayer. The Metafont sources of the fonts, and their LaTeX support, are supplied.

Inspired by the physicspackage, the package defines some simple macros for mathematical notation which make the code more readable or allow flexibility in typesetting material.

The datetime2 package provides commands for formatting dates, times and time zones and redefines \today to use the same formatting style. In addition to \today, you can also use \DTMcurrenttime (current time) or \DTMnow (current date and time). Dates and times can be saved for later use. The accompanying datetime2-calc package can be used to convert date-times to UTC+00:00. Language and regional support is provided by independently maintained and installed modules. The datetime2-calc package uses the pgfcalendar package (part of the PGF/TikZ bundle). This package replaces datetime.sty, which is now obsolete.

LuaHBTeX is a LuaTeX variant that can use the HarfBuzz engine for glyph shaping, instead of LuaTeX's built-in shaper.

This package provides documentation for Mendex (Japanese index processor).

This LaTeX package makes \hat put real hats on symbols.

This package provides a Lua module that can parse key-value options like the TeX packages keyval, kvsetkeys, kvoptions, xkeyval, pgfkeys, etc.

The makecookbook bundle contains the files needed to create a nice quality family cookbook in a form ready to submit to most print-on-demand companies. Modifiable choices have been made regarding standard book features such as trim size, margins, headers/footers, chapter heading formatting, front matter (copyright page, table of contents, etc.) and back matter (index). Commands and environments have been created to format the food stories and recipes. The user will need to: supply their own food stories and recipes(!), and install the needed fonts. We assume a LuaTeX compile.

Please note that no new document class or package is included here. Rather, we provide a modifiable preamble and a small number of other files that, together, fully support creation of all of the internal pages of a cookbook (i.e., everything except the cover art).

This package provides a tutorial aimed at introducing undergraduate students to LaTeX, including an introduction to LaTeX Workshop in Visual Studio Code and an example package of user-defined LaTeX commands.

The package defines a command \cb that positions a comma below a letter, as required (for example) in Romanian typesetting. The command is robust, but interferes with hyphenation.

Latexdiff is a Perl script for visual mark up and revision of significant differences between two LaTeX files. Various options are available for visual markup using standard LaTeX packages such as color. Changes not directly affecting visible text, for example in formatting commands, are still marked in the LaTeX source. A rudimentary revision facilility is provided by another Perl script, latexrevise, which accepts or rejects all changes. Manual editing of the difference file can be used to override this default behaviour and accept or reject selected changes only.

The textcase package offers commands \MakeTextUppercase and \MakeTextLowercase are similar to the standard \MakeUppercase and \MakeLowercase, but they do not change the case of any sections of mathematics, or the arguments of \cite, \label and \ref commands within the argument. A further command \NoCaseChange does nothing but suppress case change within its argument, so to force uppercase of a section including an environment, one might say:

\MakeTextUppercase...\NoCaseChange\beginfoo ...\NoCaseChange\endfoo...

This package provides a translation of Oetiker's original (Not so) short introduction to LaTeX2e.

LaTeX2e's filecontents and filecontents* environments enable a LaTeX source file to generate external files as it runs through LaTeX. However, there are two limitations of these environments: they refuse to overwrite existing files, and they can only be used in the preamble of a document. The filecontents package removes these limitations, letting you overwrite existing files and letting you use filecontents filecontents* anywhere.
