The sacsymb package contains symbols used in objective reduction (Orch OR) theory of consciousness as applied to the three brains model of psychological experience. These symbols are prepared using TikZ.

This package provides a LaTeX package for students of Tsinghua University to write coursework more efficiently. It can also be used by students from other universities.

This package enables writers to conveniently decorate text with linear gradient colors. The RGB values of the first and the last character are specified as parameters while the rest of the text is colored automatically.

The knuth-hint package contains the large collection of HINT documents for many of the CWEB amd WEB sources of programs in the TeX Live distribution (and, for technical reasons, PDF documents for CTWILL and XeTeX). Each program is presented in its original form as written by the respective authors, and in the changed form as used in TeX Live. Care has been taken to keep the section numbering intact, so that you can study the codes and the changes in parallel.

Also included are the errata for Donald Knuth's Computers & Typesetting. HINT is the dynamic document format created by Martin Ruckert's HiTeX engine. The HINT files can be viewed with the hintview application. The knuth-hint package is a showcase of HiTeX's capabilities.

This LaTeX package uses TikZ to draw parameterized 2D robot arms, for example to be used in educational material.

hepunits is a LaTeX package built on the SIunits package which adds a collection of useful HEP units to the existing SIunits set.

This package makes a very minor change to the operation of the \cite command so that multiple citations may break at line end. Note that the change is not necessary in unmodified LaTeX; however, there remain packages that restore the undesirable behaviour of the command as provided in LaTeX 2.09. Neither cite nor natbib make this mistake.

The package allows the user to manually markup changes of text, such as additions, deletions, or replacements. Changed text is shown in a different color; deleted text is struck out. Additionally, text can be highlighted and/or commented. The package allows free definition of additional authors and their associated color. It also allows you to change the markup of changes, authors, highlights or comments. A Python script is provided for removing the changes.

This package provides LaTeX support for section breaks, used mainly in fiction books to signal changes in a story, like changes in time, location, etc. It supports the asterism symbol, text content, or custom macros as the section break mark symbol.

This package provides a LaTeX interface to create, modify, and use the Lua data structure tables. Lua tables can be declared with the help of luakeys, and this package provides facilities to set, get, check, iterate, apply, etc., to the table.

The command-line programs pdfopen and pdfclose allow you to control the X Window System version of Adobe's Acrobat Reader from the command line or from within a (shell) script. The programs work with xpdf and evince.

The package provides the means to include arbitrary elements of LilyPond notation, including symbols from Lilypond's Emmentaler font, in a LaTeX document. The package uses OpenType fonts, and as a result must be compiled with LuaLaTeX or XeLaTeX.

This package provides tools to create your own verbatim environments, and works for all values of \endlinechar.

MLTeX is a modification of TeX that allows the hyphenation of words with accented letters using ordinary Computer Modern (CM) fonts. The system is distributed as a TeX change file.

ArabTeX is a package extending the capabilities of TeX and LaTeX to generate Arabic and Hebrew text. Input may be in ASCII transliteration or other encodings (including UTF-8); output may be Arabic, Hebrew, or any of several languages that use the Arabic script. ArabTeX consists of a TeX macro package and Arabic and Hebrew fonts (provided both in Metafont format and Adobe Type 1). The Arabic font is presently only available in the Naskhi style. ArabTeX will run with Plain TeX and also with LaTeX.

PicTeX is an early and very comprehensive drawing package that mostly draws by placing myriads of small dots to make up pictures. It has a tendency to run out of space; packages m-pictex and pictexwd deal with the problems in different ways.

This is qstest bundle, which contains the packages makematch for matching patterns to targets (with a generalization in the form of pattern lists and keyword lists), and qstest for performing unit tests, allowing the user to run a number of logged tests ensuring the consistency of values, properties and call sequences during execution of test code. Both packages make extensive use of in their package documentation, providing illustrated examples that are automatically verified to work as expected.

This is a package for creating decorative chapter headings with quotations. Uses graphical and coloured output and by default needs the Adobe standard font set (as supported by psnfss).

This package provides a replacement for LaTeX's picture macros, that uses PostScript \special commands. The package is now largely superseded by pict2e.

This package enables the user to produce and typeset one or more indices simultaneously. The package is known to work in LaTeX documents processed with pdfLaTeX, XeLaTeX and LuaLaTeX. If makeindex is used for processing the index entries, no particular setup is needed. Using xindy or other programs, it is necessary to enable shell escape. Shell escape is also needed if splitindex is used. This is a fork of imakeidx, with new features and fixed bugs.

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.

The package allows LaTeX maths users of the PX fonts to select the shapes (italic or upright) for the Greek lowercase and uppercase letters. Once the shapes for lowercase and uppercase have been selected via a package option, the \other prefix (e.g., \otheralpha) allows using the alternate glyph (as in the fourier package). The pxgreeks package does not constrain the text font that may be used in the document.

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 macros and environments that relieve the programmer of some of the difficulties of using \parshape in LaTeX macros. It does not actually calculate shapes in the way that the shapepar package does.
