The package provides tools for simple operations on lists of tokens which are not necessarily balanced. It is in particular used a lot in the unravel package, to go through tokens one at a time rather than having to work with entire braced groups at a time.

This module provides the czech style that can be set using \DTMsetstyle provided by datetime2.sty. This package is currently unmaintained.

This package provides a class and package is provided which allows TeX pictures or other TeX code to be compiled standalone or as part of a main document. Special support for pictures with beamer overlays is also provided. The package is used in the main document and skips extra preambles in sub-files. The class may be used to simplify the preamble in sub-files. By default the preview package is used to display the typeset code without margins.

This package contains the Japanese pTeX manual.

This package provides a simple interface for typesetting (complex) polynomial long division.

This is another tool for the automation of LaTeX document processing, like latexmk or arara. The main feature of this tool is that it does not clutter your working directory with .aux or .log or other auxiliary files. It has of course the usual features of automation tools. It automatically re-runs (La)TeX for cross-references. MakeIndex, BibTeX, Biber, or makeglossaries will be executed if a corresponding option is set. Furthermore, cluttex can watch input files for changes (using an external program).

The package provides a Unicode font with over 4,000 symbols to supplement the Unicode math symbols. It is compatible with and complements the AMS STIX2 math fonts, but focuses on new symbols and symbol variants more suited to work in logic.

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 package is a specialized tool built on top of PGF/TikZ for drawing spectral sequences. It provides a powerful, concise syntax for specifying the data of a spectral sequence, and then allows the user to print various pages of spectral sequences, automatically choosing which subset of the classes, differentials, and structure lines to display on each page. It also handles most of the details of the layout. At the same time, it is extremely flexible. spectralsequences is closely integrated with TikZ to ensure that users can take advantage of as much as possible of its expressive power. It is possible to turn off most of the automated layout features and draw replacements using TikZ commands. The package also provides a carefully designed error reporting system intended to ensure that it is as clear as possible what is going wrong.

AMS-TeX is a TeX macro package based on Plain TeX: it provides many features for producing more professional-looking maths formulas with less burden on authors.

This is the final archival distribution of AMS-TeX. AMS-TeX is no longer supported by the AMS, nor is it used by the AMS publishing program. The AMS does not recommend creating any new documents using AMS-TeX; this distribution will be left on CTAN to facilitate processing of legacy documents and as a historical record of a pioneering TeX macro collection that played a key role in popularizing TeX and revolutionizing mathematics publishing. AMS-TeX is the historical basis of amslatex, which should now be used to prepare submissions for the AMS.

This package offers a variety of features for documenting LaTeX packages, ensuring consistent presentation, cross-referencing, and index generation. It also supports version and change tracking to maintain a consistent change history.

The package implements the \Ucharcat command for LuaLaTeX. \Ucharcat is a new primitive in XeTeX, an extension of the existing \Uchar command, that allows the specification of the catcode as well as character code of the character token being constructed.

This Java command line application may be used to extract glossary information stored in a .bib file and convert it into glossary entry definition commands. This application should be used with glossaries-extra.sty's record package option. It performs two functions in one: it selects entries according to records found in the .aux file (similar to BibTeX), and hierarchically sorts entries and collates location lists (similar to MakeIndex or Xindy). The glossary entries can then be managed in a system such as JabRef, and only the entries that are actually required will be defined, reducing the resources required by TeX.

The supplementary application convertgls2bib can be used to convert existing .tex files containing definitions (\newglossaryentry etc.)#: to the .bib format required by bib2gls.

This package provides a family of modifications of the standard BibTeX styles whose behaviour may be changed by changing the user document, without change to the styles themselves. The package is largely used nowadays in its adaptation for working with Babel.

The package can draw dotted arrows that are extendable, in the same was as \xrightarrow.

This is a beta version of the STEP Greek font. Only a regular face is available at present, though there are plans to add italic, bold and bold italic in the future. The font only supports LGR in TeX and is meant to serve as a Greek complement to a Times-like font such as STEP. The font supports polytonic Greek.

This package aims to provide a way to easily move proofs to the appendix. You can (among other things) move proofs to different places/sections, create links from theorems to proofs, restate theorems, add comments in appendix...

MakeIndex is resolutely stuck with Latin-based alphabets, so will not deal with Greek indexes, unaided. This package provides a Perl script that will transmute the index of a Greek document in such a way that MakeIndex will sort the entries according to the rules of the Greek alphabet.

The package provides a large and sundry set of macros for the manipulation of strings. The macros are developed not merely for cosmetic application (such as changing the case of letters and string substitution), but also for programming applications such as character look-ahead, argument parsing, conditional tests on various string conditions, etc. The macros were designed all to be expandable (note that things such as \uppercase and \lowercase are not expandable), so that the macros may be strung together sequentially and nested (after a fashion) to achieve rather complex manipulations.

The GenMPage package generalizes LaTeX's minipages. Keyval options and styles can be used to determine their appearance in an easy and consistent way. It includes options for paragraph indentation and vertical alignment with respect to the visual top and bottom margins.

The package facilitates wrapping text to a specific character width, breaking lines by words rather than, as done by TeX, by characters. The primary use for these facilities is to aid the generation of messages sent to the log file or console output to display messages to the user. Package authors may also find this useful when writing out arbitrary text to an external file.

The GFSNeohellenic font, a historic font first designed by Victor Scholderer, now has native support for Mathematics. A useful application is in Beamer documents since this is a sans math font.

ltximg is a Perl script that automates the process of extracting and converting environments provided by TikZ, PStricks and other packages from input file to image formats and standalone files using Ghostscript and poppler-utils. It generates a file with only extracted environments and another with all extracted environments converted to \includegraphics.

The Ximera document class provides macros that support the creation of both PDF and online materials.
