This is yet another package for acronyms: it offers simple markup of acronyms and technical terms in the text, giving an index each of terms and acronyms with their expanded form.

Product integrals are to products, as integrals are to sums. They have been around for more than a hundred years, they have not become part of the standard mathematician's toolbox, possibly because no-one invented the right mathematical symbol for them. The authors have remedied that situation by proposing the symbol and providing this font.

This short document is about antique Spanish units used in Spain and their colonies between the sixteenth and nineteenth centuries. The next step will be to develop a LaTeX package similar to siunitx. The document could be interesting for historians, economists, metrologists and others, as a reference and detailed compendium about this old system of units.

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.

This package provides a collection of three LaTeX2e styles intended for typesetting Russian and bilingual English-Russian documents, using the lh fonts and without the benefit of Babel's language-switching mechanisms. The packages (hcyralt and hcyrwin for use under emTeX, and hcyrkoi for use under teTeX

This package provides support for the OpenType font CascadiaMono --- i.e., with LuaLaTeX or XeTeX and Fontspec --- which is a variant of CascadiaCode, but without ligatures.

Mismatches of parentheses, braces, (angle) brackets, especially in TeX sources which may be rich in those, may be difficult to trace. This little Ruby script helps you by writing your text to standard output, after adding a left margin to your text, which will normally be almost empty, but will clearly show any mismatches.

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.

MathsPIC (Perl) is a development of the earlier MathsPIC (DOS) program, now implemented as a Perl script, being much more portable than the earlier program. MathsPIC parses a plain text input file and generates a plain text output-file containing commands for drawing a diagram. It produces output containing PiCTeX and (La)TeX commands, which may then be processed by plain TeX or LaTeX in the usual way. MathsPIC also outputs a comprehensive log file. MathsPIC facilitates creating figures using PiCTeX by providing an environment for manipulating named points and also allows the use of variables and maths (advance, multiply, and divide)---in short---it takes the pain out of PiCTeX.

pst-feyn is a set of drawing graphical elements which are used for Feynman diagrams.

This package increases the width of the typeset area of an A4 page. This sort of operation is capable of producing typographically poor results; the operation itself is better provided by the geometry package.

This package creates an academic curriculum vitae (CV) from a BibTeX .bib file. The package makes use of BibLaTeX and Biber to automatically format, group, and sort the entries on a CV.

This is a COLR/CPAL-based color OpenType font from the Twemoji collection of emoji images.

The distributed drivers do not support the PGF feature of inter-picture connections under e-pTeX and dvipdfmx. The package uses existing features of dvipdfmx to fix this problem.

The package provides the commands to flag chapters or sections (or anything else destined to become a TOC line). The command \nexttocwithtags{req1,req2,...}{excl1,excl2,...} specifies which tags are to be required and which ones are to be excluded by the next \tableofcontents (or equivalent) command. In a document that uses a class where \tableofcontents may only be used once, the command \tableoftaggedcontents{req1,req2,...}{excl1,excl2,...} may be used to provide several tables.

This package provides two shorthands for typesetting breaking and non-breaking small spaces, where both hyphenation and kerning against space are correctly applied. Additionally, interword kerning can be applied.

LaTeX tables are implemented using TeX commands such as \halign, \noalign, \span, and \omit. In order to implement new features, many macro packages have modified the inner table commands inside LaTeX. This makes package code complicated, difficult to maintain, and often conflicts with each other. At present, the LaTeX3 programming layer is basically mature. This tabularray package will discard the old \halign commands and directly use LaTeX3 functions to parse the table, and then typeset the entire table. Under the premise of being compatible with the basic syntax of LaTeX2 tables, this macro package will completely separate the content and style of the table, and the style of the table can be completely set in keyval way.

The trivfloat package provides a quick method for defining new float types in LaTeX. A single command sets up a new float in the same style as the LaTeX kernel figure and table float types. The package works with memoir as well as the standard classes.

This collection contains implementations for aspects of the LaTeX3 kernel, dealing with higher-level ideas such as the Designer Interface. The packages here are considered broadly stable (The LaTeX3 Project does not expect the interfaces to alter radically). These packages are built on LaTeX2e conventions at the interface level, and so may not migrate in the current form to a stand-alone LaTeX3 format.

Packages provided are xparse, which provides a high-level interface for declaring document commands xfp, an expandable IEEE 754 FPU for LaTeX, l3keys2e, which makes the facilities of the kernel module l3keys available for use by LaTeX 2e packages, xtemplate, which provides a means of defining generic functions using a key-value syntax, and xfrac, which provides flexible split-level fractions.

The Asana-Math font is an OpenType font that includes almost all mathematical Unicode symbols and it can be used to typeset mathematical text with any software that can understand the MATH OpenType table.

This package is designed for typesetting multiple English translations of the Holy Quran. It adds 15 additional English translations to the quran package.

The package provides the means of creating hyperlinks, from a footnote at the bottom of the page, back to the occurrence of the footnote in the main text.

The package offers a collection of macros for MetaPost to make easier to draw finite-state machines, automata, labelled graphs, etc. The user defines nodes, which may be isolated or arranged into matrices or trees; edges connect pairs of nodes through arbitrary paths. Parameters, that specify the shapes of nodes and the styles of edges, may be adjusted.

This package provides the Computer Modern fonts by Donald Knuth. The Computer Modern font family is a large collection of text, display, and mathematical fonts in a range of styles, based on Monotype Modern 8A.
