This small package supports key-value syntax other than the standard LaTeX syntax of <key>=<value>. Using this package, create key-values of the form <key>:<value> or <key>-><value>, for example. The package converts the new notation to xkeyval notation and passes it on to xkeyval.

This package provides an API for template and package developers to create dynamic color schemes for light- and dark modes. For those unaware: we refer to dark mode when a document has a dark background with a light font and to light mode if it has a dark font with a light background.

This package provides tools for the flexible handling of verbatim text including: verbatim commands in footnotes; a variety of verbatim environments with many parameters; ability to define new customized verbatim environments; save and restore verbatim text and environments; write and read files in verbatim mode; build "example" environments (showing both result and verbatim source).

This package enables sub-numbering of floats (figures and tables) similar to the subequations environment of the amsmath package. The subfloat package is not to be confused with the subfig package which generates sub-figures within one normal figure, and manages their placement; subfloat only affects captions and numbering.

This package provides LaTeX, pdfLaTeX, XeLaTeX, and LuaLaTeX support for the Almendra family of fonts, designed by Ana Sanfelippo. Almendra is a typeface design based on calligraphy. Its style is related to the Chancery and Gothic hands. There are regular and bold weights with matching italics. There is also a regular-weight small-caps.

The package simulates typical word processor layout: narrow page margins, Times, Helvetica and Courier fonts, \LARGE or \Large headings, and \sloppy typesetting.

The package aims at making life easier for users who are discontent with LaTeX's standard layout settings because they need a layout that resembles the usual ``wordlike'' output.

Fira Math is a sans-serif font with Unicode math support. The design of this font is based on Fira Sans and FiraGO. Fira Math is distributed in OpenType format and can be used with the unicode-math package under XeLaTeX or LuaLaTeX. More support is offered by the firamath-otf package.

This LaTeX2e package enables the embedding of MetaPost figures within LaTeX documents. The package automatically collects the embedded definitions and figures in a .mp file, adds an appropriate LaTeX document structure, and compiles it to .mps files. It also allows for various configuration options to manage the generation of files and compilation.

The package provides commands that display the value of a LaTeX counter in a variety of formats (ordinal, text, hexadecimal, decimal, octal, binary etc). The package offers some multilingual support; configurations for use in English (both British and American usage), French (including Belgian and Swiss variants), German, Italian, Portuguese and Spanish documents are provided.

The dot2texi package allows you to embed graphs in the DOT graph description language in your LaTeX documents. The dot2tex tool is used to invoke Graphviz for graph layout, and to transform the output from Graphviz to LaTeX code. The generated code relies on the TikZ and PGF package or the PSTricks package.

Mathdots redefines \ddots and \vdots, and defines \iddots. The dots produced by \iddots slant in the opposite direction to \ddots. All the commands are designed to change size appropriately in scripts, as well as in response to LaTeX size changing commands. The commands may also be used in plain TeX.

This package provides classes extarticle, extreport, extletter, extbook and extproc which provide for documents with a base font size from 8-20pt. There is also a LaTeX package, extsizes.sty, which can be used with nonstandard document classes. But it cannot be guaranteed to work with any given class.

This package provides a Perl script that provides support for thumbnails in pdfTeX and dvips/ps2pdf. The script uses Ghostscript to generate the thumbnails which get represented in a TeX readable file that is read by the package thumbpdf.sty to automatically include the thumbnails. This arrangement works with both plain TeX and LaTeX.

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.

The package provides functionality for producing an index without directly entering index entries into the text using the \index command, but instead by looking up short keys and printing a predefined string in the main text and adding a corresponding index entry. The standard use case is the production of an index of names.

This package is an alternative to todonotes, from which it differs in the following ways: depending on where you call \snaptodo, the note is put in the left or the right margin, whichever is closer. The notes bump each other so they never overlap; the lines never overlap either. Aesthetic and customizable style.

Publications, that reference many names, require editors and proofreaders to track those names in the text and index. The package offers name authority macros that allow authors and compilers to normalize occurrences of names, variant name forms, and pen names in the text and index. This may help minimize writing and production time and cost.

This package provides some enhanced features for typesetting indexes, notably continuation text when entries or sub-entries continue from one page or column to the next and an interface for accessing marks created from index entries, so that (for example) a running head can include the range of index entries that appears on the page.

This package allows hyperref package and the natbib package with options numbers and sort&compress to work together. This means that multiple sequential citations, e.g., [3,2,1], will be compressed to [1-3], where the 1 and the 3 are (color-)linked to the bibliography.

The package can easily draw current 2-terminal devices and some 3- and 4-terminal devices used in electronic or electric theory. The package's macros are designed with a view to logical representation of circuits, as far as possible, so as to relieve the user of purely graphical considerations when expressing a circuit.

This package provides a LaTeX2e package for drawing tangles, trees, Hopf algebra operations and other pictures. It is based on emTeX or TPIC \specials. Therefore, it can be used with the most popular drivers, including emTeX drivers, dviwin, xdvi and dvips, and (using some code from ConTeXt) it may also be used with pdfLaTeX.

Edmargin provides a very simple scheme for endnote sections for critical editions. Endnotes can either be marked in the text, or with marginal references to the page in the note sections where the note is to be found. Notes can be set in individual paragraphs, or in block paragraph mode (where there are many short notes).

The rotpages package allows you to format documents where small sets of pages are rotated by 180 degrees and rearranged, so that they can be read by turning the printed copy upside-down. It was developed for collecting exercises and solutions: using the package, you can print the exercise text normally and the solutions rotated.

Lists are defined as a sequence of tokens separated by a comma. The coollist package allows the user to access certain elements of the list while neglecting others --- essentially turning lists into a sort of array. List elements are accessed by specifying the position of the object within the list (the index of the item).
