GuixSD

The package allows citations in the German style, which is considered by many to be particularly reader-friendly. The citation provides a small amount of bibliographic information in a footnote on the page where each citation is made. It combines a desire to eliminate unnecessary page-turning with the look-up efficiency afforded by numeric citations. The package makes use of BibLaTeX, and is considered experimental.

This package provides an easy and flexible user interface to customize page layout, implementing auto-centering and auto-balancing mechanisms so that the users have only to give the least description for the page layout. The package knows about all the standard paper sizes, so that the user need not know what the nominal "real" dimensions of the paper are, just its standard name (such as a4, letter, etc.). An important feature is the package's ability to communicate the paper size it's set up to the output.

This is a collection of LaTeX packages for producing color, including graphics (e.g. PostScript) files, and rotation and scaling of text in LaTeX documents. It comprises the packages color, graphics, graphicx, trig, epsfig, keyval, and lscape.

The hyperref package is used to handle cross-referencing commands in LaTeX to produce hypertext links in the document. The package provides backends for the \special set defined for HyperTeX DVI processors; for embedded pdfmark commands for processing by Acrobat Distiller (dvips and Y&Y's dvipsone); for Y&Y's dviwindo; for PDF control within pdfTeX and dvipdfm; for TeX4ht; and for VTeX's pdf and HTML backends. The package is distributed with the backref and nameref packages, which make use of the facilities of hyperref.

This package uses the (La)TeX extension -shell-escape to establish whether the document is being processed on a Windows or on a Unix-like system, or on Cygwin (Unix environment over a Windows system). Booleans provided are: \ifwindows, \iflinux, \ifmacosx and \ifcygwin. The package also preserves the output of uname on a Unix-like system, which may be used to distinguish between various classes of systems.

This package provides miscellaneous macros by Joerg Knappen, including: represent counters in greek; Maxwell's non-commutative division; latin1jk, latin2jk and latin3jk, which are inputenc definition files that allow verbatim input in the respective ISO Latin codes; blackboard bold fonts in maths; use of RSFS fonts in maths; extra alignments for \parboxes; swap Roman and Sans fonts; transliterate semitic languages; patches to make (La)TeX formulae embeddable in SGML; use maths minus in text as appropriate; simple Young tableaux.

The l3kernel bundle provides an implementation of the LaTeX3 programmers’ interface, as a set of packages that run under LaTeX 2e. The interface provides the foundation on which the LaTeX3 kernel and other future code are built: it is an API for TeX programmers. The packages are set up so that the LaTeX3 conventions can be used with regular LaTeX 2e packages.

This bundle holds prototype implementations of concepts for a LaTeX designer interface, to be used with the experimental LaTeX kernel as programming tools and kernel sup port. Packages provided in this release are:

1. l3keys2e, which makes the facilities of the kernel module l3keys available for use by LaTeX 2e packages;

2. xfrac, which provides flexible splitlevel fractions;

3. xparse, which provides a high-level interface for declaring document commands; and

4. xtemplate, which provides a means of defining generic functions using a key-value syntax.

The LH fonts address the problem of the wide variety of alphabets that are written with Cyrillic-style characters. The fonts are the original basis of the set of T2* and X2 encodings that are now used when LaTeX users need to write in Cyrillic languages. Macro support in standard LaTeX encodings is offered through the latex-cyrillic and t2 bundles, and the package itself offers support for other (more traditional) encodings. The fonts, in the standard T2* and X2 encodings are available in Adobe Type 1 format, in the CM-Super family of fonts. The package also offers its own LaTeX support for OT2 encoded fonts, CM bright shaped fonts and Concrete shaped fonts.

The package enables the user to typeset programs (programming code) within LaTeX; the source code is read directly by TeX---no front-end processor is needed. Keywords, comments and strings can be typeset using different styles. Support for hyperref is provided.

This collection of tools includes: atsupport for short commands starting with @, macros to sanitize the OT1 encoding of the cmtt fonts; a doafter command; improved footnote support; mathenv for various alignment in maths; list handling; mdwmath which adds some minor changes to LaTeX maths; a rewrite of LaTeX's tabular and array environments; verbatim handling; and syntax diagrams.

The package provides tools for creating tabular cells spanning multiple rows. It has a lot of flexibility, including an option for specifying an entry at the "natural" width of its text.

This bundle provides a package that implements both author-year and numbered references, as well as much detailed of support for other bibliography use. Also provided are versions of the standard BibTeX styles that are compatible with natbib: plainnat, unsrtnat, abbrnat. The bibliography styles produced by custom-bib are designed from the start to be compatible with natbib.

The bundle comprises various LaTeX packages, providing among others: better accessibility support for PDF files; extensible chemists reaction arrows; record information about document class(es) used; and many more.

The overpic environment is a cross between the LaTeX picture environment and the \includegraphics command of graphicx. The resulting picture environment has the same dimensions as the included graphic. LaTeX commands can be placed on the graphic at defined positions; a grid for orientation is available.

Simply changing \parskip and \parindent leaves a layout that is untidy; this package (though it is no substitute for a properly designed class) helps alleviate this untidiness.

This package simplifies the inclusion of external multi-page PDF documents in LaTeX documents. Pages may be freely selected and it is possible to put several logical pages onto each sheet of paper. Furthermore a lot of hypertext features like hyperlinks and article threads are provided. The package supports pdfTeX (pdfLaTeX) and VTeX. With VTeX it is even possible to use this package to insert PostScript files, in addition to PDF files.

This package provides a complete Babel replacement for users of LuaLaTeX and XeLaTeX; it relies on the fontspec package, version 2.0 at least.

The main purpose of the preview package is the extraction of selected elements from a LaTeX source, like formulas or graphics, into separate pages of a DVI file. A flexible and convenient interface allows it to specify what commands and constructs should be extracted. This works with DVI files postprocessed by either Dvips and Ghostscript or dvipng, but it also works when you are using PDFTeX for generating PDF files.

This package allows LaTeX constructions (equations, picture environments, etc.) to be precisely superimposed over Encapsulated PostScript figures, using your own favorite drawing tool to create an EPS figure and placing simple text "tags" where each replacement is to be placed, with PSfrag automatically removing these tags from the figure and replacing them with a user specified LaTeX construction, properly aligned, scaled, and/or rotated.

The PSNFSS collection includes a set of files that provide a complete working setup of the LaTeX font selection scheme (NFSS2) for use with common PostScript fonts. It covers the so-called "Base" fonts (which are built into any Level 2 PostScript printing device and the Ghostscript interpreter) and a number of free fonts. It provides font definition files, macros and font metrics. The bundle as a whole is part of the LaTeX required set of packages.

This is a package for processing PostScript graphics with psfrag labels within pdfLaTeX documents. Every graphic is compiled individually, drastically speeding up compilation time when only a single figure needs re-processing.

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.

This (deprecated) package provides support for the manipulation and reference of small or "sub" figures and tables within a single figure or table environment. It is convenient to use this package when your subfigures are to be separately captioned, referenced, or are to be included in the List-of-Figures. A new \subfigure command is introduced which can be used inside a figure environment for each subfigure. An optional first argument is used as the caption for that subfigure. The package is now considered obsolete: it was superseded by subfig, but users may find the more recent subcaption package more satisfactory.

This package was a predecessor of longtable; the newer package (designed on quite different principles) is easier to use and more flexible, in many cases, but supertabular retains its usefulness in a few situations where longtable has problems.

The package defines a tabular*-like environment, tabulary, taking a "total width" argument as well as the column specifications. The environment uses column types L, C, R and J for variable width columns (\raggedright, \centering, \raggedleft, and normally justified). In contrast to tabularx's X columns, the width of each column is weighted according to the natural width of the widest cell in the column.

This package facilitates tables with titles (captions) and notes. The title and notes are given a width equal to the body of the table (a tabular environment). By itself, a threeparttable does not float, but you can put it in a table or a table* or some other environment.

This package provides an interface to sectioning commands for selection from various title styles, e.g. for marginal titles and to change the font of all headings with a single command, also providing simple one-step page styles. It also includes a package to change the page styles when there are floats in a page. You may assign headers/footers to individual floats, too.

This package is a collection of (variously) simple tools provided as part of the LaTeX required tools distribution, comprising the following packages: afterpage, array, bm, calc, dcolumn, delarray, enumerate, fileerr, fontsmpl, ftnright, hhline, indentfirst, layout, longtable, multicol, rawfonts, showkeys, somedefs, tabularx, theorem, trace, varioref, verbatim, xr, and xspace.

This very short package allows you to expandably remove spaces around a token list (commands are provided to remove spaces before, spaces after, or both); or to remove surrounding spaces within a macro definition, or to define space-stripped macros.

LaTeX, by default, restricts the sizes at which you can use its default computer modern fonts, to a fixed set of discrete sizes (effectively, a set specified by Knuth). The type1cm package removes this restriction; this is particularly useful when using scalable versions of the CM fonts (Bakoma, or the versions from BSR/Y&Y, or True Type versions from Kinch, PCTeX, etc.). In fact, since modern distributions will automatically generate any bitmap font you might need, type1cm has wider application than just those using scalable versions of the fonts. Note that the LaTeX distribution now contains a package fix-cm,f which performs the task of type1cm, as well as doing the same job for T1- and TS1-encoded ec fonts.

The bundle provides the ucs package, and utf8x.def, together with a large number of support files. The utf8x.def definition file for use with inputenc covers a wider range of Unicode characters than does utf8.def in the LaTeX distribution. The package provides facilities for efficient use of its large sets of Unicode characters. Glyph production may be controlled by various options, which permits use of non-ASCII characters when coding mathematical formulae. Note that the bundle previously had an alias “unicode”; that alias has now been withdrawn, and no package of that name now exists.

Typewriter-style fonts are best for program listings, but Computer Modern Typewriter prints ` and ' as bent opening and closing single quotes. Other fonts, and most programming languages, print ` as a grave accent and ' upright; ' is used both to open and to close quoted strings. The package switches the typewriter font to Computer Modern Typewriter in OT1 encoding, and modifies the behaviour of verbatim, verbatim*, \verb, and \verb* to print in the expected way. It does this regardless of other fonts or encodings in use, so long as the package is loaded after the other fonts were. The package does not affect \tt, \texttt, etc.

The command \url is a form of verbatim command that allows linebreaks at certain characters or combinations of characters, accepts reconfiguration, and can usually be used in the argument to another command. The command is intended for email addresses, hypertext links, directories/paths, etc., which normally have no spaces, so by default the package ignores spaces in its argument. However, a package option allows spaces, which is useful for operating systems where spaces are a common part of file names.

The varwidth environment is superficially similar to minipage, but the specified width is just a maximum value — the box may get a narrower “natural” width.

The wasy2WASY2 (Waldi Symbol) font by Roland Waldi provides many glyphs like male and female symbols and astronomical symbols, as well as the complete lasy font set and other odds and ends. The wasysym package implements an easy to use interface for these symbols.

This package allows figures or tables to have text wrapped around them. It does not work in combination with list environments, but can be used in a parbox or minipage, and in two-column format.

The package starts from the basic facilities of the colorcolor package, and provides easy driver-independent access to several kinds of color tints, shades, tones, and mixes of arbitrary colors. It allows a user to select a document-wide target color model and offers complete tools for conversion between eight color models. Additionally, there is a command for alternating row colors plus repeated non-aligned material (like horizontal lines) in tables.

Lualibs is a collection of Lua modules useful for general programming. The bundle is based on Lua modules shipped with ConTeXt, and made available in this bundle for use independent of ConTeXt.

This package provides the Metafont base files needed to build fonts using the Metafont system.

MetaPost uses a language based on that of Metafont to produce precise technical illustrations. Its output is scalable PostScript or SVG, rather than the bitmaps Metafont creates.

Contains files used to build the Plain TeX format, as described in the TeXbook, together with various supporting files (some also discussed in the book).

Texinfo is the preferred format for documentation in the GNU project; the format may be used to produce online or printed output from a single source. The Texinfo macros may be used to produce printable output using TeX; other programs in the distribution offer online interactive use (with hypertext linkages in some cases).

This is a very limited subset of the TeX Live distribution. It includes little more than the required set of LaTeX packages.

Texmaker is a program that integrates many tools needed to develop documents with LaTeX, in a single application.

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.

To torify applications (to take measures to ensure that an application, which has not been designed for use with Tor such as ssh, will use only Tor for internet connectivity, and also ensures that there are no leaks from DNS, UDP or the application layer) you need to install torsocks.

Torsocks allows you to use most socks-friendly applications in a safe way with Tor. It ensures that DNS requests are handled safely and explicitly rejects UDP traffic from the application you're using.
