Many of David Carlisle's more substantial packages stand on their own, or as part of the LaTeX latex-tools set; this set contains: making dotless j characters for fonts that don't have them; a method for combining the capabilities of longtable and tabularx; an environment for including plain TeX in LaTeX documents; a jiffy to create slashed characters for physicists.

This package eases the typesetting of notation of semantics and compilers. It includes T-diagrams, various derivation symbols and inference trees.

This package provide the binary for texlive-velthuis.

The package extends and improves the robustness of the pgfkeys package. In particular, it can deal with active comma, equality sign, and slash in key parsing. The difficulty with active characters has long been a problem with the pgfkeys package. The package also introduces handlers beyond those that pgfkeys can offer.

The package suppresses fi and fl (and other ligatures) in Serbian text written using Roman script.

This package provides horizontally and vertically split elliptical (pairs of) nodes in TikZ. The package name derives from the fact that split ellipses of this type are used to represent Single-World Intervention Graph (SWIG) models which are used in counterfactual causal inference.

This style file provides macros for named tensor notation.

This package provides fonts (as Metafont source) for Old English, Indic languages in Roman transliteration and Puget Salish (Lushootseed) and other Native American languages.

This package offers tools to draw simple or barely complex schemes of chemical processes. The package defines several standard symbols and styles to draw process units and streams. The guiding light of the package is the UNICHIM regulation.

This package provides commands that make it easy to highlight terms in equations and add annotation labels using TikZ. It should work with pdfLaTeX as well as LuaLaTeX.

TeX-Gyre-Math is a collection of maths fonts to match the text fonts of the TeX-Gyre collection. The collection is available in OpenType format, only; fonts conform to the developing standards for OpenType maths fonts. TeX-Gyre-Math-Bonum (to match TeX-Gyre-Bonum), TeX-Gyre-Math-Pagella (to match TeX-Gyre-Pagella), TeX-Gyre-Math-Schola (to match TeX-Gyre-Schola) and TeX-Gyre-Math-Termes (to match TeX-Gyre-Termes) fonts are provided.

The package makes a quick hack to ziffer to display numbers in maths mode according to ISO 31-0, regardless of input format (European $1.235,7$ or Anglo-American $1,235.7$).

It is well known that high or deep cells tend to touch the \hlines of a tabular. This package provides a modifier S acting on usual column types so that to ensure a minimal distance that can be controlled through two parameters \cellspacetoplimit and \cellspacebottomlimit.

This package is an as complete as possible manual about bibliographies in LaTeX, and thus mainly about BibTeX.

The class was developed to typeset a dissertation at ETH Zurich. The requirements were to use A5 paper and 10pt type.

The package is not advertised for public use, but is necessary for the support of others of the author's packages (which are compiled under the ltxdoc class).

The package collects a set of graphical elements based on PStricks that can be used to facilitate display of attachment systems such as two differently shaped surfaces with or without a fluid wedged in between. These macros ease the display of wet adhesion models and common friction systems such as boundary lubrication, elastohydrodynamic lubrication and hydrodynamic lubrication.

This package provides a package with three dark color themes for Beamer, designed for presentations with pictures and/or for bright rooms without screen. These themes mix one dominant foreground colour and a black background. Cormorant stands for green, Frigatebird for red and Magpie for blue.

The package will read text in one alphabet, and provide a transliterated version in another; this is useful for readers who cannot read the original alphabet. The package can make allowance for hyphenation.

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

This package provides commands for typesetting left indices. Unlike other similar packages, leftindex also indents the left superscript, providing much better spacing in general.

The package uses PStricks and pst-solides3d to draw three dimensional ribbons on a cylinder, torus, sphere, cone or paraboloid. The width of the ribbon, the number of turns, the colour of the outer and the inner surface of the ribbon may be set. In the case of circular and conical helices, one may also choose the number of ribbons.

The package provides tools for defining LaTeX commands and environments using combinations of parameters and keys. All the facilities of the ltxkeys and skeyval packages are available to the user of skeycommand.
