This class is designed to simplify the typesetting of problem sheets with mathematics and computer science content. It is currently customised towards teaching in French (and the examples are in French).

Sometimes it is necessary to be able to refer to subexpressions of an equation. In order to do that these subexpressions should be numbered. In standard LaTeX there is no provision for this. The subeqn package solves this. Note that this package is not compatible with the package subeqnarray, but it can be used together with the LaTeX class options leqno and fleqn.

The package provides the language definition file for support of Romanian in Babel. Translations to Romanian of standard LaTeX names are provided.

The package enables selection of 5 standard Japanese fonts for pLaTeX and dvips.

This package provides a simple and highly configurable way to use Unicode and OpenType mathematics with simple LuaTeX, taking advantage of most of the engine's new capabilities in mathematical typesetting. Also included are the proper settings and definitions for almost all Unicode mathematical characters.

The package provides gb4e users two relative example reference commands: \Next refers to the next example in the document and \Prev refers to the previous example. No explicit label command is required.

The package generalises the macro patching commands provided by P. Lehmann's etoolbox. The difference between this package and its sibling xpatch is that this package sports a very powerful \regexpatchcmd based on the l3regex module of the LaTeX3 experimental packages.

This package provides automatic handling of additional kinds of material by or during memoization with Memoize. It also provides support for memoizing content in tagged PDFs and compatibility with ltx-talk. TikZ pictures tagged with alt, actualtext or artifact are handled automatically.

This package causes \_ in text mode (i.e., \textunderscore) to print an underscore so that hyphenation of words either side of it is not affected; a package option controls whether an actual hyphenation point appears after the underscore, or merely a break point. The package also arranges that, while in text, _ itself behaves as \textunderscore (the behaviour of _ in maths mode is not affected).

The package allows the user to filter out unwanted warnings and error messages issued by LaTeX, packages and classes, so they won't pop out when there's nothing one can do about them. Filtering goes from the very broad (``avoid all messages by such and such'') to the fine-grained (``avoid messages that begin with...''). Messages may be saved to an external file for later reference.

In LaTeX typesetting, one usually needs to use different variants of a math symbol to clarify the meanings. For example, in linear algebra literature, it is common to use boldfaced symbols to represent vectors, and normal symbols to represent scalars. However, applying these variants by typing \mathbf, \mathrm commands manually can be daunting. This package aims to provide an automatic and customizable approach for math symbol styling which eliminates the need to enter style commands repeatedly.

The horoscop package provides a unified interface for astrological font packages; typesetting with pict2e of standard wheel charts and some variations, in PostScript- and PDF-generating TeX engines; and access to external calculation software (Astrolog and Swiss Ephemeris) for computing object positions.

The file hatching.mp contains a set of MetaPost macros for hatching interior of closed paths.

This package provides a collection of some Devanagari fonts by EkType: Mukta, Baloo, Modak, and Jaini.

The package allows the user to generate multiple documents from a single source, by marking pieces of the document with tags and specifying which marked pieces to include or exclude.

Creation of title pages is something most authors should not have to do. But reality is not perfect, so a lot of authors have to do it. This package not only provides several pages for the title instead of only one --- at least five are typical for a thesis! ---, it also provides a bunch of predefined titlepage styles with several standard elements, and optionally additional elements.

The package provides macros for typesetting phonological rules like those in Sound Pattern of English (Chomsky and Halle 1968).

The package extends the ifthen package, providing extra predicates for the package's \ifthenelse command. The package is complementary to xifthen, in that they provide different facilities; the two may be loaded in the same document, as long as xifthen is loaded first.

Writing a TeX length with \the writes the value and the unit without a space. Package isopt provides a macro \ISO which inserts a user defined space between number and unit.

The lstfiracode package defines FiraCodeStyle for the use with the listings package. This style contains almost all ligatures in Fira Code family of fonts.

This package provides a LaTeX class implementing the guidelines on scientific writing of the art history institute (Kunstgeschichtliches Institut) at Ruhr University Bochum.

This package uses the (La)TeX extension -shell-escape to establish whether the document is being processed on a Windows or on a Unix-like system, or on Cygwin.

Booleans provided are: \ifwindows, \iflinux, \ifmacosx and \ifcygwin. The package also preserves the output of uname on a Unix-like system, which may be used to distinguish between various classes of Unix systems.

This package provides Metafont (by Donald Knuth) and Adobe Type 1 (by Taco Hoekwater) versions of the font containing the odd symbols Knuth uses in his books. LaTeX support is available using the manfnt package.

Typesetting derivatives and differentials in a consistent way are clumsy and require care to ensure the preferred formatting. Several packages have been developed for this purpose, each with its own features and drawbacks, with the most ambitious one being diffcoeff. While this package is comparable to diffcoeff in terms of features, it takes a different approach. One difference is this package provides more options to tweak the format of the derivatives and differentials. However, the automatic calculation of the total order isn't as developed as the one in diffcoeff. This package makes it easy to write derivatives and differentials consistently with its predefined commands. It also provides a set of commands that can define custom derivatives and differential operators. The options follow a consistent naming scheme making them easy to use and understand.
