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).

The Helmholtz-Ellis JI Pitch Notation (HEJI), devised in the early 2000s by Marc Sabat and Wolfgang von Schweinitz, explicitly notates the raising and lowering of the untempered diatonic Pythagorean notes by specific microtonal ratios defined for each prime. It provides visually distinctive logos distinguishing families of justly tuned intervals that relate to the harmonic series. These take the form of strings of additional accidental symbols based on historical precedents, extending the traditional sharps and flats. Since its 2020 update, HEJI version 2 (HEJI2) provides unique microtonal symbols through the 47-limit. This package is a simple LaTeX implementation of HEJI2 that allows for in-line typesetting of microtonal accidentals for use within theoretical texts, program notes, symbol legends, etc. Documents must be compiled using XeLaTeX.

This package provides a patch for LaTeX bugs tools/3180 and tools/3480. The patch applies to version 4.11 of longtable.

The package contains a number of PostScript fonts derived from the STIX OpenType fonts that may be used in maths mode in regular and bold weights for Calligraphic, Fraktur and Double-struck alphabets. Virtual fonts with metrics suitable for maths mode are provided, as are LaTeX support files.

The package can float text around figures and tables which do not span the full width of a page; it improves upon floatfig, and allows tables/figures to be set left/right or alternating on even/odd pages.

This package provides commands for naming, initializing and configuring theorem-like environments. These commands have key-value based interfaces and are especially useful in multilingual documents, allowing the easy declaration of theorem-like environments that can automatically adapt to the language settings.

This class wraps the default article and extends it for a homogeneous look of hand-in assignments at university (RWTH Aachen University, Computer Science Department), specifically in the field of computer science, but easily extensible to other fields. It provides macros for structuring exercises, aggregating points, and displaying a grading table, as well as several macros for easier math mode usage.

The package offers a means to set up hyphenation suitable for several languages and/or dialects, and to select them or switch between them while typesetting.

This package generates the letterhead of the UWA. It requires the UWA logo in PDF format, which is available in SVG format at https://static-listing.weboffice.uwa.edu.au/visualid/core-rebrand/img/uwacrest/, and uses the Arial and UWA Slab fonts by default. The package works with XeLaTeX and LuaLaTeX.

The package helps to enables grid typesetting in double column documents. Grid typesetting (vertical aligning of lines of text in adjacent columns) is a difficult task in LaTeX, and the present package is no more than an attempt to help users to achieve it in a limited way.

This package is for adding license license:data to bibliography entries via BibLaTeX's built-in related mechanism. It provides a new related type license and some bibmacros for typesetting these related entries.

The package uses collectbox to define variants of common box related macros which read the content as real box and not as macro argument. This enables the use of verbatim or other special material as part of this content. The provided macros have the same names as the original versions but start with an upper-case letter instead. The long-form macros, like \Makebox, can also be used as environments, but not the short-form macros, like \Mbox. However, normally the long form uses the short form anyway when no optional arguments are used.

This package provides the PlayFairDisplay family of fonts, designed by Claus Eggers Sorensen, for use with LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX. PlayFairDisplay is well suited for titling and headlines. It has an extra large x-height and short descenders. It can be set with no leading if space is tight, for instance in news headlines, or for stylistic effect in titles. Capitals are extra short, and only very slightly heavier than the lowercase characters. This helps achieve a more even typographical colour when typesetting proper nouns and initialisms.

This package provides a mechanism to control the space after commas and semicolons in mathematical expressions.

This package (once part of the exsheets package), provides a framework for providing multilingual features to a LaTeX package. The package has its own basic dictionaries for English, Brazilian, Catalan, Dutch, French, German, Polish and Spanish. It aims to use translation material for English, Dutch, French, German, Italian, Spanish, Catalan, Turkish, Croatian, Hungarian, Danish and Portuguese from babel or polyglossia if either is in use in the document.

This package provides a new command \newfontx. It is similar to the old (and deprecated) command \newfont in function, but is more compatible with NFSS. In particular, one can safely change font size after invoking a font command defined by \newfontx.

The package allows selection of Latin Modern Typewriter fonts with scaling and access to all its features.

The package aims to facilitate Russian typesetting (based on input using MicroSoft Code Page 1251). Russian hyphenation is selected, and various mathematical commands are set up in Russian style. Furthermore all Cyrillic letters catcodes are set to letter, so that commands with Cyrillic letters in their names may be defined.

The overpic environment is a cross between the LaTeX picture environment and the \includegraphics command of graphicx. The resulting picture environment has the same dimensions as the included graphic. LaTeX commands can be placed on the graphic at defined positions; a grid for orientation is available.

The package provides a set of macros for naturally typesetting electrical and electronic networks. It is designed as a tool that is native to LaTeX, and directly supporting PDF output format. It has therefore been based on the PGF/TikZ package.

This package provides a tokenizer for LaTeX. \GetTokens{Target1}{Target2}{Source} splits source into two tokens at the first encounter of a comma. The first token is saved in a newly created command with the name passed as <Target1> and the second token likewise. A package option trim causes leading and trailing space to be removed from each token; with this option, the \TrimSpaces command is defined, which removes leading and trailing spaces from its argument.

These packages are either mandated by the core LaTeX team, or very widely used and strongly recommended in practice.

Many font families available for use with LaTeX are available at multiple weights. Many Type 1-oriented support packages for such fonts re-define the standard \mddefault or \bfdefault macros. This can create difficulties if the weight desired for one font family isn't available for another font family, or if it differs from the weight desired for another font family. The package provides a solution to these difficulties.

The package provides a flexible mechanism for annotating, and commenting upon, collaboratively-written documents.
