This package implements a LaTeX class for writing exercise sheets for a lecture. Its features are:

• quick typesetting of exercise sheets or their revisions,

• simple user friendly commands,

• elegant page formatting,

• automatic numbering of exercises and sub-exercises,

• the number of the exercise sheet is extracted automatically from the file name,

• static information about the lectures and the authors needs to provided at one point only.

The macros in this package model the construction of linguistic tree structures as a genuinely graphical problem: they contain two types of objects, ``branches'' and ``node labels'', and these are positioned relative to a ``grid''. It is essential that each of these three elements is constructed independent of the other two, and hence they can be modified without unwanted side effects. The macros are based on the XY-Pic package.

The package defines cross-references (essentially grand label references), which may be listed in a table of cross-references.

This package modifies LaTeX's array and tabular environments to keep text from touching other text or hlines above or below. Several new parameters are defined and some standard macros are re-defined. The package slows down compilation of tables, since each entry is boxed twice.

The cidarticle bundle is used for writing articles to be published in the Commentarii informaticae didacticae (CID).

This package may be used to define the last point where some code shall be executed.

Executing Lua code from within TeX with directlua can sometimes be tricky: there is no easy way to use the percent character, counting backslashes may be hard, and Lua comments don't work the way you expect. The package provides the \luaexec command and the luacode environments to help with these problems.

The postage package is used for franking letters with Deutsche Post's online postage service Internetmarke. Note that in order to print valid stamps you must point to a valid PDF of Deutsche Post's Ausdruck 4-spaltig (DIN A4).

Typesetting bagpipe music in MusixTeX is needlessly tedious. This package provides specialized and re-defined macros to simplify this task.

This package (like luarandom, but without the obligation to use LuaLaTeX) provides some macros for creating random integer number lists. This list can have multiple numbers or not, and this list can be sorted or not.

This package provides yet another solution to some well known typesetting problems solved in a variety of ways: multi line formulas with paired and nested delimiters. It tackles the problem at the Lua level. As a byproduct, delimiters can be scaled in various ways, inner delimiters come in different flavors like relational and binary operators, punctuation symbols etc., and outer delimiters can be selected automatically according to the nesting level. Last but not least, delimiter groups can even extend across several array cells or across the whole document. A special environment is provided as well, which allows multi line expressions to be placed inside a displayed equation and make TeX do the line splitting and alignment.

The package uses PSTricks to draw the Julia and Mandelbrot sets, the Sierpinski triangle, Koch flake, and Apollonius Circle as well as fractal trees (which need not be balanced) with a variety of different parameters (including varying numbers of iterations).

The bundle contains an extended version (xbtxbst.doc) of the source of the standard BibTeX styles, together with corresponding versions of the standard styles. The styles offer support for CODEN, ISBN, ISSN, LCCN, and PRICE fields, extended PAGES fields, the PERIODICAL entry, and extended citation label suffixing.

The package provides tools for a mathematical style that conforms to the International Standard ISO 80000-2 and is common in science and technology. It changes the default shape of capital Greek letters to italic, sets up bold italic and sans-serif bold italic math alphabets with Latin and Greek characters, and defines macros for markup of vector, matrix and tensor symbols.

The package allows you to set arbitrary sizes for the main font of the document, through the fontsize=<size> option.

This module provides the german style that can be set using \DTMsetstyle provided by datetime2.sty.

The package enables the user to typeset exams with multiple choice, open questions and many other types of exercise. Both questions and answers may be randomly distributed within the exam, and the solutions are typeset automatically. Exercises may contain a wide number of random parameters and it is possible to do arithmetical operations on them. The package is localised in Italian, English, French, German, Greek, Serbian, and Spanish.

This package allows you to include Gnuplot graphs in your LaTeX documents. The Gnuplot code is extracted from the document and written to .gnuplot files. Then, if shell escape is used, the graph files are automatically processed to graphics or LaTeX code files which will then be included in the document. If shell escape isn't used, the user will have to manually convert the files by running Gnuplot on the extracted .gnuplot files.

This package provides all the necessary LaTeX frontends for the Bangla language and comes with some fonts of its own.

The layout design is relatively straightforward; the class uses the Bookman and the BrushScript-Italic fonts.

This package adds the \keyboard[1][2]..[7] command to your project. When used, it draws a small 2 octaves piano keyboard on your document, with up to 7 keys highlighted.

The package modifies the annotation commands and label-test mechanism of the ednotes package so that critical notes appear on the pages and in the order that one would expect.

The package provides the means of listing an entire BibTeX database, avoiding the potentially large (macro) impact associated with \nocite{*}.

With this package you can create fully connected neural networks in a simple and efficient way.
