Complexity is a LaTeX package that defines commands to typeset Computational Complexity Classes such as $\P$ and $\NP$ (as well as hundreds of others). It also offers several options including which font classes are typeset in and how many are defined (all of them or just the basic, most commonly used ones).

This exam class is specially designed for mathematics teachers in China. Using BHCexam you can separate the format and the content very well; export both teacher paper and student paper; typeset multiple choice questions with 3-6 options keeping adaptively neat alignment; typeset cloze questions with a customizable underline; typeset questions with subquestions in lists; group questions in a list to control whether to show score, leave spacing, initialize question number; and more.

The package fetches from the system the date of last modification or opening of an existing file, using the function \pdffilemoddate; the user may specify how the date is to be presented.

The package can be used to facilitate exercise counting and exercise point counting in a LaTeX document. It counts the number of exercises and it sums all the points of the exercises in a document. Especially for exams it is also common to have an overview of all exercises and their maximal points. This is also supported by this package by providing a macro to retrieve the points of each exercise.

FdSymbol is a maths symbol font, designed as a companion to the Fedra family, but it might also fit other contemporary typefaces.

This package augments the fancyvrb and listings packages to allow the source code they contain to be checked by an external tool (like a compiler). The external tool's messages can be automatically reincorporated into the original document. The package does not focus on a specific programming language, but it is designed to work well with languages and compilers in the ML family.

The package redefines the commands \emph and \textit so that parentheses and square brackets are typeset in an upright font in their arguments.

This package provides a class that produces overhead slides (transparencies), with many facilities. Seminar is not nowadays reckoned a good basis for a presentation — users are advised to use more recent classes such as powerdot or beamer, both of which are tuned to 21st-century presentation styles.

The package produces crossword grids, using a wide variety of colours and decorations of the grids and the text in them. The package uses TikZ for its graphical output.

The package provides plotting of data (typically from external files), using PSTricks. Plots may be configured using a wide variety of parameters.

This package provides support for many indexes, leaving all the bookkeeping to LaTeX and MakeIndex. No extra programs or files are needed. One runs latex and makeindex as if there is just one index. In the main file one puts commands like \setindex{main} to steer the flow. Some features of MakeIndex may no longer work.

The package implements macros for plain TeX to typeset the notation invented by Gottlob Frege in 1879 for his books Begriffsschrift and Grundgesetze der Arithmetik (two volumes). The output styles of both books are supported.

Mathabx is a set of three mathematical symbols font series. They are defined by Metafont code. The package includes Plain TeX and LaTeX support macros. A version of the fonts, in Adobe Type 1 format, is also available.

EasyDTX is a variant of the DTX format which eliminates the need for all those pesky macrocode environments. Any line introduced by a single comment counts as documentation, and documentation lines may be indented. An .edtx file is converted to a .dtx by a Perl script called edtx2dtx. There is also a rudimentary Emacs mode, implemented in easydoctex-mode.el, which takes care of fontification, indentation, and forward and inverse search.

This package allows drawing a URL as a QR code into the margin of a one- or two-sided document.

This package, together with the Beamer class, is used to generate slideshows with song lyrics. This is typically used in religious services in churches equipped with a projector, for which this package has been written, but it can be useful for any type of singing assembly. It provides environments to describe a song in a natural way, and formatting it into slides with overlays. The package comes with an additional Python script that can be used to convert plain-text song lyrics to the expected LaTeX markup.

This is a development of the long-established diagmac package, using pict2e so that the restrictions on line direction are removed.

The bundle provides two classes for usage by KdG University College professors and master students: kdgcoursetext for writing course texts, and kdgmasterthesis for writing master's theses.

Libre Franklin is an interpretation and expansion based on the 1912 Morris Fuller Benton's classic, designed by Pablo Impallari, Rodrigo Fuenzalida and Nhung Nguyen.

This package extends the \hhline command with a !{...} token, which allows creating lines with arbitrary LaTeX commands.

The package offers a collection of useful macros for disciplines related to signal processing. It defines macros for plotting a sequence of numbers, drawing the pole-zero diagram of a system, shading the region of convergence, creating an adder or a multiplier node, placing a framed node at a given coordinate, creating an up-sampler or a down-sampler node, drawing the block diagram of a system, drawing adaptive systems, sequentially connecting a list of nodes, and connecting a list of nodes using any node-connecting macro.

Cascadia Code is a monospaced font by Microsoft. This package provides the Cascadia Code family of fonts with support for LaTeX and pdfLaTeX.

This package defines and implements the data type bit set, a vector of bits. The size of the vector may grow dynamically. Individual bits can be manipulated.

The package defines two environments for typesetting algorithms in LaTeX2e. The algtab environment is used to typeset an algorithm with automatically numbered lines. The algorithm environment can be used to encapsulate the algtab environment algorithm in a floating body together with a header, a caption, etc. \listofalgorithms is defined.
