Starting with PDF 1.3, PDF files can contain file attachments, i.e., arbitrary files that a reader can extract, just like attachments to an e-mail message. The attachfile package brings this functionality to pdfLaTeX and provides some additional features such as the ability to use arbitrary LaTeX code for the file icon. Settings can be made either globally or on a per-attachment basis. attachfile makes it easy to attach files and customize their appearance in the enclosing document.

The package defines macros and other utilities to design Reo Circuits.

This LaTeX package provides a command \scsnowman which can display many variants of snowman

The package provides font encoding definitions for unicode fonts loaded by LaTeX in XeTeX or LuaTeX. The package provides two encodings: EU1, designed for use with XeTeX, which the fontspec uses for unicode fonts which require no macro-level processing for accents, and EU2, which provides the same facilities for use with LuaTeX. Neither encoding places any restriction on the glyphs provided by a font; use of EU2 causes the package euxunicode to be loaded (the package is part of this distribution). The package includes font definition files for use with the Latin Modern OpenType fonts.

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.

The package provides a macro for reflecting images, in a number of different ways, in pursuit of more striking graphics in a document.

These files fix and/or enhance some math glyphs and are loaded in the math font goodie files used by ConTeXt LMTX.

The package is designed to create graph diagrams as simply as possible, using TikZ.

Chicago is a BibTeX style that follows the B reference style of the 13th Edition of the Chicago manual of style; a LaTeX package is also provided. The style was derived from the newapa style.

This package puts a grid on the paper. It was written for developers of a class or package who have to put elements on definite locations on a page (e.g., letter class). The grid allows a faster optical check, whether the positions are correct. If the previewer already offers features for measuring, the package might be unnecessary. Otherwise it saves the developer from printing the page and measuring by hand.

This package provides macros for a two language dictionary.

The bera package contains the Bera Type 1 fonts and files to use the fonts with LaTeX. Bera is a set of three font families: Bera Serif (a slab-serif Roman), Bera Sans (a Frutiger descendant) and Bera Mono (monospaced/typewriter). The Bera family is a repackaging, for use with TeX, of the Bitstream Vera family.

This package will provide a complete implementation of unicode maths for XeLaTeX and LuaLaTeX. Unicode maths is currently supported by the following fonts:

• Latin Modern Math,

• TeX Gyre Bonum Math,

• TeX Gyre Pagella Math,

• TeX Gyre Schola Math,

• TeX Gyre Termes Math,

• DejaVu Math TeX Gyre,

• Asana-Math fonts,

• STIX,

• XITS Math,

• Libertinus Math,

• Fira Math.

The package provides a Perl script that converts a .sty file (LaTeX package) to .dtx format (documented LaTeX source), by surrounding macro definitions with macro and macrocode environments. The macro name is automatically inserted as an argument to the macro environment. Code lines outside macro definitions are wrapped only in macrocode environments. Empty lines are removed. The script should not be thought to be fool proof and 100% accurate but rather as a good start to the business of making a .dtx file from an undocumented style file. Full .dtx files are generated. A template based on the skeleton file from dtxtut is used. User level macros are added automatically to the Usage section of the .dtx file. A corresponding .ins file can be generated as well.

This package enables LaTeX users to create math books for middle and high schools. It provides commands to create the front page of the manual and the chapters. Each chapter can consist of three sections: the lesson, the exercises and the activities.

Kpathsea is a library and utility programs which provide path searching facilities for TeX file types, including the self-locating feature required for movable installations, layered on top of a general search mechanism. This package provides supporting files.

This package provides a tool to keep a master source, consisting of different chunks intended for different audiences. The tool allows extracting the versions intended for different audiences and to incorporate the changes made in any of these versions into the master document.

The sTeX package collection is a version of (La)TeX that allows marking up (La)TeX documents semantically without leaving the document format, essentially turning it into a document format for mathematical knowledge management (MKM).

The package provides a comprehensive and flexible set of commands for combinations of left and right sub- and superscripts.

The package provides the means of establishing a consistent set of fonts for use in a LaTeX document. It allows mixing and matching the Type 1 font sets available on the archive. Font-set definition takes the form of a set of options that are read when the package is loaded: for each typographic category (main body font, sans-serif font, monospace font, mathematics fonts, text figures, and so on), a font or a transformation is given in those options. The approach enables the user to remember their own configurations (as a single command) and to borrow configurations that other users have developed.

The package provides a collection of styles for BibLaTeX. It was designed for citations in German Humanities, especially film studies, and offers some features that are not provided by the standard BibLaTeX styles. The style is highly optimized for documents written in German, and the main documentation is only available in German.

Algorithm2e is an environment for writing algorithms. An algorithm becomes a floating object (like figure, table, etc.). The package provides macros that allow you to create different keywords, and a set of predefined key words is provided; you can change the typography of the keywords. The package allows vertical lines delimiting a block of instructions in an algorithm, and defines different sorts of algorithms such as Procedure or Function; the name of these functions may be reused in the text or in other algorithms.

The confproc collection comprises a class, a BibTeX style, and some scripts for generating conference proceedings.

This package provides a simple class that allows production of an invoice, with or without VAT; different addresses for delivery and for billing are permitted.
