There are commands, classes and packages which are outdated and superseded. The nag package provides routines to warn the user about the use of such obsolete things.

The MetaPost package latexMP implements a user-friendly interface to access LaTeX-based typesetting capabilities in MetaPost. The text to be typeset is given as string. This allows even dynamic text elements, for example counters, to be used in labels. Compared to other implementations it is much more flexible, since it can be used as direct replacement for btex.etex, and much faster, compared for example to the solution provided by tex.mp.

This package provides some simple decoration fonts made with TikZ, for short texts: paint brush, ink brush, pixelart brush, and bicolor texts.

This package provides the command \thepagecolor, which gives the current page (background) color, i.e., the argument used with the most recent call of \pagecolor{...}. The command \thepagecolornone gives the same color as \thepagecolor, except when the page background color is none (e.g., as a result of using the \nopagecolor command). In that case \thepagecolor is white and \thepagecolornone is none. When \nopagecolor is unknown or broken (crop package), this package provides a replacement. Similar to \newgeometry and \restoregeometry of the geometry package \newpagecolor{...} and \restorepagecolor are provided. For use with the crop package \backgroundpagecolor{...} as well as \newbackgroundpagecolor{...} and \restorebackgroundpagecolor are provided.

This package typesets HTML directly from LaTeX. It can handle almost all of HTML2, and most of the math fragment of the draft HTML3.

This package causes \_ in text mode (i.e., \textunderscore) to print an underscore so that hyphenation of words either side of it is not affected; a package option controls whether an actual hyphenation point appears after the underscore, or merely a break point. The package also arranges that, while in text, _ itself behaves as \textunderscore (the behaviour of _ in maths mode is not affected).

The package automatically collects multiple \bibitem references, which always appear in the same sequence in \cite, into a single \bibitem block.

This package allows you to put your document under a license and include a link to read about the license or include an icon or image of the license. Currently, only Creative Commons is supported, but this package is designed to handle all kinds of licenses.

The package allows the attachment of an arbitrary superior figures font to a font family that lacks one. (Superior figures are commonly used as footnote markers.) Two superior figures fonts are provided --- one matching Times, the other matching Libertine.

This is a set of packages providing XML parsing, UTF-8 parsing, Unicode entities, and common formatting object definitions for JadeTeX.

This package provides Ethiopian language support for the Babel package, including a collection of fonts and TeX macros for typesetting the characters of the languages of Ethiopia, with Metafont fonts based on EthTeX's. The macros use the Babel framework.

This is a package built for collaboratively editing LaTeX documents and tracking changes. Through highly configurable commands, the user can choose how their and their collaborators modifications appear in the document. Additional tools are provided to help keep track of where the edits are made within the PDF.

This package extends the \xinteval syntax to do algebra in Q(phi) (where phi is the golden ratio), and compute Fibonacci numbers, Zeckendorf representations of positive integers and Bergman phi-representations of the positive elements of Z[phi]. The $ character is used to compute the Knuth Fibonacci multiplication. Being based upon xintexpr, it allows to compute with ``arbitrarily'' big integers, the reasonable use being with integers of at most a few hundreds of digits.

The current version does special formatting for the first line of text in a paragraph. The package is part of a larger body of tools which remain in preparation.

The package lets you change page layout parameters in small steps over a range of values using options. It can set \textwidth appropriately for the main fount, and ensure that the text fits inside the printable area of a printer. An rmpage-formatted document can be typeset identically without rmpage after a single cut and paste operation. Local configuration can set defaults: for all documents; and by class, by printer, and by paper size. The geometry package is better if you want to set page layout parameters to particular measurements.

The package lets you shade or colour the cells in the alignment environments such as \halign and LaTeX's tabular and array environments. The colortbl package is to be preferred today with LaTeX (it assures compatibility with the longtable package, which is no longer true with colortab); another modern option is the table-colouring option of the xcolor. However, colortab remains an adequate solution for use with Plain TeX.

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 is used in concert with the cyber package to make documents with annotations of compliance with cybersecurity requirements. When you include this package, some notations of compliance are added to section names as seen in the table of contents of the final document. It also makes your document more brittle in unexpected ways: for example, when you use cybercic in the same document as hyperref, you cannot use any formatting in your section titles. So don't use cybercic unless you need to.

This package modifies two aspects of TeX's automatic interatom mathematics spacing. It uses LuaTeX's \Umath primitives to make superscripts and subscripts more closely resemble \textstyle and \displaystyle math and to treat \mathinner subformulas as \mathord, effectively eliminating this class.

This package contains the source of the examples printed in The LaTeX Graphics Companion book, together with necessary supporting files.

This style is primarily aimed at Italian legal jurists and provides them with the ability to cite legal materials, such as legislative acts, regulations, soft law, treaties and case law. Additionally, the style codifies the most prevalent citation practices among Italian legal scholars.

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

This package provides macros and Type 1 fonts for Typesetting the Cherokee language with the Omega version of LaTeX (known as Lambda).

This package provides a drop-in replacement for the Palatino font from Adobe's basic set.
