This package provides interfaces to allow creating ZUGFeRD or Faktur-X invoices with LaTeX including the XML file. It can be used to modify personal invoicing templates to fulfill the requirements for digital invoicing without further modification of the invoicing processes.

This package provides macros to typeset some general mathematical operators (identity operator, trace, diagonal, rank, ...), a powerful implementation of the bra-ket notation (kets, bras, brakets, matrix elements etc. which can be sized as required), delimited expressions such as averages and norms, and some basic Lie algebra/group names. Macros for entropy measures for quantum information theory (smooth min- and max-entropy, smooth relative entropies, etc.) are also provided.

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 typesets invoices with automatic VAT and calculation of totals. It supports internationalization, invoices are typeset with booktabs for readability. It does not support separate projects per invoice. It can be used as a replacement for invoice in most cases.

This module provides the lsorbian style that can be set using \DTMsetstyle provided by datetime2.sty. This package is currently unmaintained.

This package provides a collection of experimental programs and developments based on, or complementary to, the matter in his distribution directories.

This package provides customized theorem-like environments specifically designed for computer science documents. It offers a set of pre-defined theorem styles and environments to streamline the creation of theorems, definitions, remarks, and other common structures in computer science papers and documents.

The package allows the drawing of Euclidean geometric figures using TeX PSTricks macros for specifying mathematical constraints. It is thus possible to build point using common transformations or intersections. The use of coordinates is limited to points which controlled the figure.

The LaTeX package cascade provides a command \Cascade to do constructions to present mathematical demonstrations with successive braces for the deductions.

This package provides a package to typeset proof trees for natural deduction calculi, sequent-like calculi, and similar.

The package provides a set of macros based on PSTricks to draw medical pedigrees according to the recommendations for standardized human pedigree nomenclature. The drawing commands place the symbols on a pspicture canvas. An interface for making trees is also provided. The package may be used both with LaTeX and PlainTeX. A separate Perl program for generating TeX files from spreadsheets is available.

The package supports drawing proof trees of the kind often used in introductory logic classes, especially those aimed at students without strong mathemtical backgrounds. Hodges (1991) is one example of a text which uses this system. When teaching such a system it is especially useful to annotate the tree with line numbers, justifications and explanations of branch closures. The package provides a single environment, prooftree, and a variety of tools for annotating, customising and highlighting such trees. A cross-referencing system is provided for trees which cite line numbers in justifications for proof lines or branch closures.

This package provides an abstraction for creating PRISMA 2009 flow diagrams in LaTeX. It simplifies the process of building these diagrams by providing intuitive commands while maintaining full compatibility with TikZ.

This is a 4-page reminder of what LaTeX does. It is designed for printing on A4 paper, double-sided, and folding once to A5. Such an imposed version of the document is provided in the distribution, as PDF. An analogous version is provided in legal format.

The package makes a quick hack to ziffer to display numbers in maths mode according to ISO 31-0, regardless of input format (European $1.235,7$ or Anglo-American $1,235.7$).

The typewriter package uses the OpenType Computer Modern Unicode Typewriter font, together with a LuaTeX virtual font setup that introduces random variability in grey level and angle of each character.

The scripture package provides a set of macros for typesetting quotations from the Bible. It provides many features commonly seen in bibles such as dropped text for chapter numbers, superscripts for verse numbers, indented lines for poetry sections, narrow sections and hanging paragraphs. A reference for the quotation can optionally be added.

This bundle contains several bibliography styles for separating a document's references by the first letter of the first author/editor in the bibliography entry. The styles are adapted from standard ones or from natbib ones.

Clara is a type family created specially by Seamas O Brogain. The family includes italic, bold, bold italic, and small capitals, while the character set includes (monotonic) Greek, Cyrillic, ogham, phonetic and mathematical ranges, scribal abbreviations and other specialist characters. The fonts also include some OpenType features (such as ligature substitution, small capitals, and old-style numerals) and variant forms for particular languages.

This package defines macros \makeendnotes, which converts \footnote to produce endnotes; and \theendnotes which prints them out.

The willowtreebook class is a simple book class, which the author uses for his lecture notes to be found on his web page Benjamin McKay. It actually just selects options for the more sophisticated memoir class.

This package adds label texts to an existing image with the aid of TikZ. This may be used to label certain features in an image.

This package provides an Italian translation of the l2tabu practical guide to LaTeX2e by Mark Trettin. It focuses on obsolete packages and commands.

The package used to provide macros that emulated the colour stack functionality of Dvips. The colour stack deals with colour manipulations when asynchronous events (like page-breaking) occur. For current releases of pdfTeX, this package is not needed, since real colour stacks are available. It has therefore become empty stub that does nothing at all, just in case there are still documents that reference it.
