Epigrafica is a Greek and Latin font, forked from the development of the Cosmetica font, which is a similar design to Optima and includes Greek.

This is a PSTricks package to draw moiré patterns.

The package provides the means of writing code in a modular fashion: big macros or functions are divided into small chunks (called gates) with names, which can be externally controlled (e.g., they can be disabled, subjected to conditionals, loops...) and/or augmented with new chunks. Thus complex code may easily be customised without having to rewrite it, or even understand its implementation: the behavior of existing gates can be modified, and new ones can be added, without endangering the whole design. This allows code to be hacked in ways the original authors might have never envisioned. The gates package is implemented independently for both TeX and Lua. The TeX implementation, running in any current environment, requires the texapi package, whereas the Lua version can be run with any Lua interpreter, not just LuaTeX.

This package allows using a new field realauthor, which indicates the real author of a work, when published in a pseudepigraphic name.

The package defines macros using SS to type Greek letters so that the user may type SSa to get the effect of $\alpha$. However, it takes care only of letters which have a macro name like \alpha or \Omega.

The package provides means to draw linguistic syntactic trees with ease and to support hopefully sufficient functionalities, that the linguist may need.

This package defines environments that allow page breaks inside framed boxes whose edges may be variously fancy. The bundle includes a few examples (shaded box, box with a wavy line on its side, etc).

These list-processing macros avoid the reassignments employed in the macros shown in Appendix D of the TeXbook: all the manipulations take place in what Knuth is pleased to call ``TeX's mouth''.

This package provides a package for typesetting a variety of graphs and diagrams with TeX. Xy-pic works with most formats (including LaTeX, AMS-LaTeX, AMS-TeX, and plain TeX). The distribution includes Michael Barr's diag package, which was previously distributed stand-alone.

This package is only a wrapper for the two packages libertinus-type1 (pdfLaTeX) and libertinus-otf (LuaLaTeX and XeLaTeX). The Libertinus fonts are similar to Libertine and Biolinum, but come with math symbols.

This package provides an assignment and experiment report template free of configuration designed for undergraduates on the three campuses of Harbin Institute of Technology.

This package provides LaTeX and pdfLaTeX support for the Nunito family of fonts, designed by Vernon Adams.

The float package provides commands to define new floats of various styles (plain, boxed, ruled, and userdefined ones); the rotating package provides new environments (sidewaysfigure and sidewaystable) which are rotated by 90 or 270 degrees. But what about new rotated floats, e.g., a rotated ruled one? This package makes this possible; it builds a bridge between the two packages and extends the commands from the float package to define rotated versions of the new floats, too.

Biber is a BibTeX replacement for users of BibLaTeX. It supports full UTF-8, can (re)-encode input and output, supports highly configurable sorting, dynamic bibliography sets and many other features.

The package defines auxiliary TikZ styles useful for overlaying pictures elements in Beamer.

This package allows simple typesetting in Arabic script, intended for mixed Arabic/Latin script usage in situations where heavy-duty solutions are discouraged. The system operates with both Unicode and transliterated input, allowing the user to choose the most appropriate approach for every situation.

Digestif is a code analyzer, and a language server, for LaTeX, plain TeX, ConTeXt and Texinfo. It provides context-sensitive completion, documentation, code navigation, and related functionality to any text editor that speaks the LSP protocol.

This is a Lua(La)TeX macro package that supports typesetting Korean documents including Old Hangul texts. As LuaTeX has opened up access to almost all the hidden routines of TeX engine, users can obtain more beautiful outcome using this package rather than other Hangul macros operating on other engines.

The package provides a set of macros for constructing block diagrams, using TikZ.

This is a translation of the documentation that comes with the psfrag package.

The package provides a simple, though fancy float environment to document terminal sessions --- like command executions or shell operations. The look and feel of the package output imitates the look of a shell prompt.

This package provides a .bst reference style file for the journal Zootaxa that publishes contributions in zoology and classification. This is a fork of apa.bst.

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.

These packages provide support for, and documentation in, English.
