MFLua is an extension of Metafont which embeds a Lua interpreter. It doesn’t introduce any new primitives, so a Metafont file can be used with MFLua without any modification to produce exactly the same result.

The mcite package allows the user to collapse multiple citations into one, as is customary in physics journals. The package requires a customised BibTeX style for its work; the documentation explains how to do that customisation.

This small package aims to provide two simple commands and many options to easily write linear operators as they appear in many-body physics, quantum theory, and linear algebra, in any of the ways commonly in use.

The Plain TeX program (typed in the shape of the towers of Hanoi) serves both as a game and as a TeX programming exercise. As a game, it will solve the towers with (up to) 15 discs.

The file processes to produce (real) rulers; the author suggests printing them on transparent plastic and trimming for use as a real ruler. The rule widths are 0.05mm, which can be challenging for (old) laser printers.

Instead of having to transform the common source into program or documentation, the central idea was to develop a method to have one common source which can be interpreted by a Prolog system as well as by LaTeX.

The basic operations (addition, subtraction, multiplication, division, power to an integer) are implemented by TeX macros in this package. Operands may be numbers with arbitrary numbers of digits; scientific notation is allowed. The expression scanner is also provided.

The package contains commands for students and teachers of introductory physics. Commands for physical quantities intelligently handle SI units so the user need not do so. There are other features that should make LaTeX easy for introductory physics students.

The EMISA LaTeX package is provided for preparing manuscripts for submission to EMISA, and for preparing accepted submissions for publication as well as for typesetting the final document by the editorial office.

The package defines commands that create macros for typesetting vectors, matrices and functions, in a logical way. For example, logical indexing can then be used to refer to elements or arguments without hard-coding the symbols in the document.

The package defines the \efbox command, which creates a box just wide enough to hold the text created by its argument. The command optionally puts a (possibly partial) frame around the box, and allows setting the box background colour.

This package provides a LaTeX environment numcases to produce multi-case equations with a separate equation number for each case. There is also a subnumcases environment which numbers each case with the overall equation number plus a letter.

This package provides a cult Greek font from the eighties, used at the University of Crete, Greece. It belonged to the first TeX installation in a Greek University and most probably the first TeX installation that supported the Greek language.

This package is a rewrite of the multibibliography package providing multiple bibliographies with different sorting. The new version offers a number of citation commands, streamlines the creation of bibliographies, ensures compatibility with the natbib package, and provides other improvements.

With pxpic you draw pictures pixel by pixel. It was inspired by a lovely post by Paulo Cereda, among other things (most notably a beautiful duck) showcasing the use of characters from the Mario video games by Nintendo in LaTeX.

The package provides virtual fonts and LaTeX support files for mathematical calligraphic fonts based on the rsfs Adobe Type 1 fonts, with the slant substantially reduced. The output is quite similar to that from the Adobe Mathematical Pi script font.

These are the Computer Modern fonts extended with Russian letters, in Metafont sources and ATM Compatible Type 1 format. The fonts are provided in KOI-7, but virtual fonts are available to recode them to three other Russian 8-bit encodings.

The package is designed to produce from BibTeX or BibLaTeX bibliographical databases the different indices of authors and works cited which are called indices locorum citatorum. It relies on a specific \icite command and can operate with either BibTeX or BibLaTeX.

The macros enable the user to draw simple circuit diagrams in the picture environment, with no need of special resources. The macros are appropriate for drawing for school materials. The circuit symbols accord to the various parts of the standard IEC 617.

The pecha class provides an environment for writing Tibetan on LaTeX2e in the traditional Tibetan Pecha layout used for spiritual or philosophical texts, using the cTib4TeX package. It provides features like headers in different languages, page numbering in Tibetan and more.

The package provides a Unicode font with over 4,000 symbols to supplement the Unicode math symbols. It is compatible with and complements the AMS STIX2 math fonts, but focuses on new symbols and symbol variants more suited to work in logic.

This package, initially based on pxfonts, provides many fixes and enhancements to that package, and splits it in two parts (newpxtext and newpxmath) which may be run independently of one another. It provides scaling, improved metrics, and other options.

This package provides a Type 1 font with images of the 42 counties of Romania, constructed using a general method which is described in detail in the documentation. The package name is an abbreviation of judetele Romaniei (i.e., counties of Romania).

This package provides a package to scale a document by sqrt(2) (or by \magstep{2}). This is useful if you are preparing a document on, for example, A5 paper and want to print on A4 paper to achieve a better resolution.
