This package provides two macros for drawing chord diagrams, as may be found for example in chord charts/books and educational materials. They are composed as TikZ pictures and have several options to modify their appearance.

texdoc is a Lua script providing easy access to the documentation in TeX Live: PDF, DVI, plain text files, and more. Viewing and other configuration can be extensively customized.

This package provides expandable arithmetic operations with big integers that can exceed TeX's number limits.

The package provides the means to extract specific content from a source document and write that to a target document. One could, for instance, use this to extract all exercises from lecture notes and generate an exercises book on the fly. The package also provides an environment which writes its body entirely to the target file. Another environment will write to the target file, but will also execute the body. This allows sharing code (for instance, a preamble) between the source document and the target file. Finally, the package provides an interface to conditionally extract content. With a single package option, one can specify exactly which commands (counted from the start of the document) should be extracted and which not. This might be useful for extracting specific slides from a presentation and use them in a new file.

Product integrals are to products, as integrals are to sums. They have been around for more than a hundred years, they have not become part of the standard mathematician's toolbox, possibly because no-one invented the right mathematical symbol for them. The authors have remedied that situation by proposing the symbol and providing this font.

The package builds on the standard LaTeX packages graphics and allows external LaTeX source files to be included, in the same way as graphic files, by \includegraphics. In effect, then package adds support for the .tex extension.

This package provides Computer Modern Unicode fonts. Some characters in several fonts are copied from Blue Sky Type 1 fonts released by AMS. Currently the fonts contain glyphs from Latin, Cyrillic, Greek code sets and IPA extensions. This font set contains 33 fonts. This archive contains AFM, PFB and OTF versions; the OTF version of the Computer Modern Unicode fonts works with TeX engines that directly support OpenType features, such as XeTeX and LuaTeX.

This package provides a Serbian language module for glossaries package.

Hepnames provides a pair of LaTeX packages, heppennames and hepnicenames, providing a large set of pre-defined high energy physics particle names built with the hepparticles package. The packages are based on pennames.sty by Michel Goosens and Eric van Herwijnen. Heppennames re-implements the particle names in pennames.sty, with some additions and alterations and greater flexibility and robustness due to the hepparticles structures, which were written for this purpose. Hepnicenames provides the main non-resonant particle names from heppennames with more friendly names.

This package provides a package to provide different types of arrow heads to be used with MetaPost commands

This package provides an extension to Babel greek option for typesetting classical Greek with a philological approach. The package works with the author's greek fonts using the Lispiakos font shape derived from that of the fonts used in printers shops in Lispia.

This ConTeXt module provides an easy-to-use interface for creating presentations for use with a digital projector. The presentations are not interactive (no buttons, hyperlinks or navigational tools such as tables of contents). Graphics may be mixed with the text of slides. The module provides several predefined styles, designed for academic presentation. Most styles are configurable, and it is easy to design new styles.

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.

This package provides a LaTeX environment numcases to produce multi-case equations with a separate equation number for each case. There is also a subnumcases environment which numbers each case with the overall equation number plus a letter.

This package loads url by default and defines possible URL breaks for all alphanumerical characters, as well as =, /, ., :, *, -, ~, and ". All arguments which are valid for url can be used and will be passed on to this package.

The hyperref package is used to handle cross-referencing commands in LaTeX to produce hypertext links in the document. The package provides backends for the \special set defined for HyperTeX DVI processors; for embedded pdfmark commands for processing by Acrobat Distiller (dvips and Y&Y's dvipsone); for Y&Y's dviwindo; for PDF control within pdfTeX and dvipdfm; for TeX4ht; and for VTeX's pdf and HTML backends. The package is distributed with the backref and nameref packages, which make use of the facilities of hyperref.

This bundle contains the LaTeX packages utf8add.sty and utf8hax.sty. The utf8add package provides additional support for the use of UTF-8 encoded input. This is intended for making LaTeX input more readable. The utf8hax package is using UTF-8 characters for easier access to math in LaTeX, however making the LaTeX input less readable.

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 the binaries for texlive-ptex.

This package implements KIX codes as used by the Dutch PTT for bulk mail addressing. (Royal Mail 4 State Code.)

This package provides procedures for using spot colours in LaTeX documents and the generated PDF files. Predefined templates for PANTONE and HKS colour spaces are included but new ones can easily be defined.

The ESK package allows encapsulating Sketch files in LaTeX sources. This is very useful for keeping illustrations synchronized with the text. It also frees the user from inventing descriptive names for new files that fit into the confines of file system conventions. Sketch is a 3D scene description language by Eugene K. Ressler and can generate TikZ and PSTricks code. ESK behaves in a similar fashion to EMP (which encapsulates MetaPost files), and was in fact developed from it.

The package creates documentation from C source code, or other programming languages.

This package provides a method for defining category code table stacks in LuaTeX. It is required by the luatexbase package which uses ctablestack to provide a back-compatibility form of this concept.
