The tclldoc package and class simplify the application of the doc/docstrip style of literate programming with Tcl. The tclldoc package is a bit like the doc package is for LaTeX, whereas the tclldoc class more parallels the ltxdoc class.

This package is a modern reimplementation of package everyshi, providing various commands to be executed before a \shipout command. It makes use of e-TeX’s facilities if they are available. The package may be used either with LaTeX or with plain TeX.

XeTeX is a TeX typesetting engine using Unicode and supporting modern font technologies such as OpenType, TrueType or Apple Advanced Typography (AAT), including OpenType mathematics fonts. XeTeX supports many extensions that reflect its origins in linguistic research; it also supports micro-typography (as available in pdfTeX). XeTeX was developed by the SIL (the first version was specifically developed for those studying linguistics, and using Macintosh computers). XeTeX's immediate output is an extended variant of DVI format, which is ordinarily processed by a tightly bound processor (called xdvipdfmx), that produces PDF.

The package provides citations according with the house style of the Historische Zeitschrift, a German historical journal.

The package helps to keep track of formal concepts for a specific field or document. This is particularly useful for scientific papers (for example, in physics, mathematics or computer science), which may introduce several concepts (with their own symbols). The package's commands allow the user to define a concept (typically, near its first use), and will ensure consistent use throughout the document.

This package provides Occitan language description file for Polyglossia.

This package provides a list environment which sets a description-like list in which the indentation corresponds to the longest item of the list.

The package is used in documentation files; with it the code listings will highlight (for example) pairs of curly braces with matching colors. Other delimiters like \if ... \fi, are highlighted, as are the names of new commands. All this makes code a little more readable, and helps during process of writing. Three options are provided, including a non-color option designed for printing (which numbers delimiters and underlines new commands).

This package provides a common style of proof used in propositional and predicate logic is Fitch proofs, in which each line of the proof has a statement and a justification, and subproofs within a larger proof have boxes around them. The package provides environments for typesetting such proofs and boxes. It creates proofs in a style similar to that used in Logic in Computer Science by Huth and Ryan.

The tabularray package offers a nice way to typeset tables, keeping contents and style separated. The tblr-extras package implements extra libraries to use the caption package alongside tabularray, and translated strings for continuation text in tabularray headers.

The hep-font package loads standard font packages and extends the usual Latin Modern implementations by replacing missing fonts with Computer Modern counterparts.

The package provides horizontal alignment, as in the LaTeX command \listfiles. Uses may include in-text tables, or even code listings.

This package provides a package for multiple accents in mathematics, with nice features concerning the creation of accents and placement of scripts.

The package extracts information in .bib files, makes it available in the current document, and sorts lists of entries according to that information and the user's specifications. Citation and bibliography styles can then be written directly in TeX, without any use of BibTeX. The package works with all formats that use plain TeX's basic syntactic sugar; the distribution includes a third-party file for ConTeXt and a style file for LaTeX.

The bundle contains documentation files for Japanese pBibTeX and upBibTeX. For historical reasons, this also contains old documentation files for JBibTeX.

This package provides a calligraphic font in the handwriting style. The font is supplied as Metafont source. LaTeX support of the font is provided in the calligra package in the fundus bundle.

Fontspec is a package for XeLaTeX and LuaLaTeX. It provides an automatic and unified interface to feature-rich AAT and OpenType fonts through the NFSS in LaTeX running on XeTeX or LuaTeX engines.

This bundle is an extension to the babel package for multilingual typesetting. It provides all the necessary macros, definitions and settings to typeset German documents. The bundle includes support for the traditional and reformed German orthography as well as for the Austrian and Swiss varieties of German.

Dvipdfmx (formerly dvipdfm-cjk) is a development of dvipdfm created to support multi-byte character encodings and large character sets for East Asian languages. Dvipdfmx, if called with the name dvipdfm, operates in a dvipdfm compatibility mode, so that users of the both packages need only keep one executable. A secondary design goal is to support as many PDF features as does pdfTeX.

The package provides the means to use PDF drawing primitives to produce high quality, colored graphics. It uses Bezier curves (integral and rational) from degree one to seven, allows TeX typesetting in the graphic, offers most of the standard math functions, allows plotting normal, parametric and polar functions. The package has linear, logx, logy, logxy and polar grids with many specs; it can rotate, clip and do many nice things easily it has two looping commands for programming and many instructive example files.

ctan_chk is a basic Gawk program that uses CTAN's published guidelines for authors to help eliminate sloppiness in uploaded files/projects. It is completely open for users to program additional guidelines as well as CTAN's future adjustments.

This is a LaTeX package for creating CJK character calligraphy practicing sheets (copybooks). Currently, only XeTeX is supported.

This package offers the user an easy way to typeset the Holy Quran. It provides several macros for typesetting the whole or any part of the Quran based on its popular division, including Surah, Ayah, Juz, Hizb, Quarter, and Page. Besides the Arabic original, translations to English, German, French, and Persian are provided, as well as an English transliteration.

The package is designed to produce from BibTeX or BibLaTeX bibliographical databases the different indices of authors and works cited which are called indices locorum citatorum. It relies on a specific \icite command and can operate with either BibTeX or BibLaTeX.
