The package can generate thumb indexes for your document. It features printing thumb indexes on one- or two-sided pages, along with background- and foreground-color selection and full LaTeX styling of the chapter numbers in the thumb indexes. The height of each thumb index is automatically chosen based on the number of chapters in your document, while the width is chosen by the user. The package is designed to work with the memoir class, and also requires PerlTeX and TikZ.

The labyrinth package provides code and an environment for typesetting simple labyrinths with LaTeX, and generating an automatic or manual solution path.

This package provides a DVI driver to produce an ASCII representation of the document.

This is the multiscript version of Biber. It must be used with the multiscript version of biblatex-ms.

The package provides syntax highlighting for the Q# language, a domain-specific language for quantum programming.

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.

The (Sherlock Holmes) book contains a code which uses dancing men as glyphs. The alphabet as given is not complete, lacking f, j, k, q, u, w, x and z, so those letters in the font are not due to Conan Doyle.

The code required word endings to be marked by the dancing man representing the last letter to be holding a flag: these are coded as A-Z. In some cases, the man has no arms, making it impossible for him to hold a flag. In these cases, he is wearing a flag on his hat in the character. The font is distributed as Metafont source.

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.

MiniPlot is a package to help the LaTeX user typeset EPS figures using an easy-to-use interface. Figures can be arranged as one-figure-only or as a collection of figures in columns and rows which can itself contain sub-figures in columns and rows. Wrapped figures are also supported. This package provides commands to display a framebox instead of the figure as the graphics package does already but additionally it writes useful information such as the label and scaling factor into these boxes.

This LaTeX package provides macros to describe REST APIs for documentation purposes. The endpoints can hold the following information: method description path parameter request body and content type response body, content type and status code.

This package integrates the letter class with fancyhdr and geometry to automatically make letterhead stationery. It is useful for writing letters, fax, and memos. You can set up an address book using wrapper macros. You put all the information for a person into a wrapper and then put the wrapper in a document. The class handles letterheads automatically. You place the object for the letterhead (picture, information, etc.) in a box and all sizing is set automatically.

TikZ-layers is a tiny package that provides, alongside background, typical graphical layers on TikZ: behind, above and glass. The layers may be selected with one of the styles on behind layer, on above layer, on glass layer as an option to a scope environment.

PDF documents containing formulas generated by LaTeX are usually not accessible by assistive technologies for visually impaired people and people with special educational needs (i.e., by screen readers and braille displays). The axessibility package manages this issue, allowing to create a PDF document where the formulas are read by these assistive technologies, since it automatically generates hidden comments in the PDF document (by means of the /ActualText attribute or suitable tags) in correspondence to each formula.

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.

The class provides the necessary framework for electronic submission of masters theses and PhD dissertations at the University of California, Berkeley. It is based on the memoir class.

The esint package permits access to alternate integral symbols when you are using the Computer Modern fonts. In the original set, several integral symbols are missing, such as \oiint. Many of these symbols are available in other font sets (pxfonts, txfonts, etc.), but there is no good solution if you want to use Computer Modern. The package provides Metafont source and LaTeX macro support.

This package includes fonts for African languages. The fonts are provided as Metafont source, in the familiar arrangement of lots of preamble files and a modest set of glyph specifications.

This package provides font encodings, metrics and Lua script fragments for generating font support packages for 8-bit engines with l3build. An optional template-based system enables the automatic generation of font tables and l3build tests. It also eases addition of variable scaling to .fd files (unsupported by some tools).

It is primarily designed for fontinst, but can be adapted for use with other programs. Default configuration is intended to be cross-platform and require only tools included in TeX Live, but the documentation includes a simple adaption for integration with FontForge and GNU make.

This package provides macros for typesetting virtual keyboards limited to two octaves for showing notes represented by a colored circle. Optionally, the number used for pitch analysis can be shown. It is an extension of piano.sty. It features extended syntax and several options, like setting the color, adding numbers for pitch analysis, one or two octaves, and others.

This package provides an exam class for Hefei University of Technology (China).

The package allows you to place a picture on the title page (cover page) of a LaTeX document. The package currently only works with the document classes article, report and book.
