This is a temporary package, which is used during a test phase to load the new PDF management code of LaTeX. The new PDF management code offers backend independant interfaces to central PDF dictionaries, tools to create annotations, form Xobjects, to embed files, and to handle PDF standards. The code is provided, during a testphase, as an independant package to allow users and package authors to safely test the code. At a later stage it will be integrated into the LaTeX kernel (or in parts into permanent support packages), and the current testphase bundle will be removed.
acquired package info from repodata DB: repodata/f1f85c23079e7764ad00378a9fc5d660b89a03657290e75426caf7be5b7da462-primary.sqlite.bz2
Unicode font encoding definitions for XeTeX
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.
Replace strings in encapsulated PostScript figures
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.
Provides a command to print a number with (potentially different) separators every three digits in the parts either side of the decimal point (the point itself is also configurable). The macro is fully expandable and not fragile (unless one of the separators is). There is also a command \sepnumform, that may be used when defining \the<counter> macros.
The package implements a pretty extensive scheme to make more manageable the business of configuring LaTeX output.
These packages are either mandated by the core LaTeX team, or very widely used and strongly recommended in practice.
A bundle of versatile classes and packages
The KOMA-Script bundle provides replacements for the article, report, and book classes with emphasis on typography and versatility. There is also a letter class. The bundle also offers: a package for calculating type areas in the way laid down by the typographer Jan Tschichold, a package for easily changing and defining page styles, a package scrdate for getting not only the current date but also the name of the day, and a package scrtime for getting the current time. All these packages may be used not only with KOMA-Script classes but also with the standard classes. Since every package has its own version number, the version number quoted only refers to the version of scrbook, scrreprt, scrartcl, scrlttr2 and typearea (which are the main parts of the bundle).
Subliminal refinements towards typographical perfection
The package provides a LaTeX interface to the micro-typographic extensions that were introduced by pdfTeX and have since also propagated to XeTeX and LuaTeX: most prominently, character protrusion and font expansion, furthermore the adjustment of interword spacing and additional kerning, as well as hyphenatable letterspacing (tracking) and the possibility to disable all or selected ligatures. These features may be applied to customisable sets of fonts, and all micro- typographic aspects of the fonts can be configured in a straight-forward and flexible way. Settings for various fonts are provided. Note that character protrusion requires pdfTeX, LuaTeX, or XeTeX. Font expansion works with pdfTeX or LuaTeX. The package will by default enable protrusion and expansion if they can safely be assumed to work. Disabling ligatures requires pdfTeX or LuaTeX, while the adjustment of interword spacing and of kerning only works with pdfTeX. Letterspacing is available with pdfTeX or LuaTeX. The alternative package `letterspace', which also works with plain TeX, provides the user commands for letterspacing only, omitting support for all other extensions.
The package is a toolbox of programming facilities geared primarily towards LaTeX class and package authors. It provides LaTeX frontends to some of the new primitives provided by e-TeX as well as some generic tools which are not strictly related to e-TeX but match the profile of this package. Note that the initial versions of this package were released under the name elatex. The package provides functions that seem to offer alternative ways of implementing some LaTeX kernel commands; nevertheless, the package will not modify any part of the LaTeX kernel.
A collection of recommended add-on packages for LaTeX which have widespread use.
The package loads the fixltx2e package from the LaTeX distribution, and etex.sty from the e-TeX distribution. The package then patches the \- (discretionary hyphen command) to use the current hyphen character (which may be different from than the default, which is the character at the ASCII hyphen slot), and loads the realscripts to patch the \textsuperscript command (from the LaTeX kernel) and the \textsubscript command (from the fixltx2e package). The package is loaded by the fontspec package, so that it should not ordinarily be necessary to load it explicitly. The package relies on the metalogo package for typesetting the XeTeX and XeLaTeX logos.
Bug-classification for LaTeX related bugs
The package is written in order to help identifying the rightful addressee for a bug report. The LaTeX team asks that it will be loaded in any test file that is intended to be sent to the LaTeX bug database as part of a bug report.
A collection of logos with bookmark support
The package defines a single command \hologo, whose argument is the usual case-confused ASCII version of the logo. The command is bookmark-enabled, so that every logo becomes available in bookmarks without further work.
Customising captions in floating environments
The caption package provides many ways to customise the captions in floating environments like figure and table, and cooperates with many other packages. Facilities include rotating captions, sideways captions, continued captions (for tables or figures that come in several parts). A list of compatibility notes, for other packages, is provided in the documentation. The package also provides the "caption outside float" facility, in the same way that simpler packages like capt-of do. The package supersedes caption2.
Specify arbitrary fonts for mathematics in XeTeX
The mathspec package provides an interface to typeset mathematics in XeLaTeX with arbitrary text fonts using fontspec as a backend. The package is under development and later versions might to be incompatible with this version, as this version is incompatible with earlier versions. The package requires at least version 0.9995 of XeTeX.
Can handle almost all of HTML2, and most of the math fragment of the draft HTML3.
Extended index for LaTeX including multiple indexes
This is a reimplementation of LaTeX's indexing macros to provide better support for indexing. For example, it supports multiple indexes in a single document and provides a more robust \index command. It supplies short hand notations for the \index command (^{word}) and a * variation of \index (abbreviated _{word}) that prints the word being indexed, as well as creating an index entry for it.
This package can be used to attach files to a PDF document. It is a further development of Scott Pakin's package attachfile for pdfTeX. Apart from bug fixes, this package adds support for dvips, some new options, and gets and writes meta information data about the attached files.
This package provides hooks into \sshipout called \EveryShipout and \AtNextShipout analogous to \AtBeginDocument. With the introduction of the LaTeX hook management this package became obsolete in 2020 and is only provided for backwards compatibility. For current versions of LaTeX it is only mapping the hooks to the original everyshi macros. In case you use an older LaTeX format, everyshi will automatically fall back to its old implementation by loading everyshi-2001-05-15.
The package provided hooks whose arguments are executed just after LaTeX has loaded a new font by means of \selectfont. It has become obsolete with LaTeX versions 2021/01/05 or newer, since LaTeX now provides its own hooks to fulfill this task. For newer versions of LaTeX everysel only provides macros using LaTeX's hook management due to compatibility reasons. See lthooks-doc.pdf for instructions how to use lthooks instead of everysel.
Make landscape pages display as landscape
The package adds PDF support to the landscape environment of package lscape, by setting the PDF /Rotate page attribute. Pages with this attribute will be displayed in landscape orientation by conforming PDF viewers.
Extended file name support for graphics (legacy package)
The original package extended the file name processing of package graphics to support a larger range of file names. The base LaTeX code now supports multiple dots and spaces, and this package by default is a stub that just loads graphicx. However, \usepackage{grffile}[=v1] may be used to access version 1(.18) of the package if that is needed.
Unicode mathematics support for XeTeX and LuaTeX
This package will provide a complete implementation of unicode maths for XeLaTeX and LuaLaTeX. Unicode maths is currently supported by the following fonts: Cambria Math (Microsoft), Minion Math (Johannes Kuster, typoma GmbH) Latin Modern Math (Boguslaw Jackowski, Janusz M. Nowacki) TeX Gyre Pagella Math (Boguslaw Jackowski, Janusz M. Nowacki) Asana-Math fonts (Apostolos Syropolous), Neo Euler (Khaled Hosny), STIX (STI Pub), and XITS Math (Khaled Hosny). As well as running XeTeX or LuaTeX, this package requires recent versions of the fontspec, expl3, xpackages, filehook, ucharcat and lualatex-math packages.
Advanced font selection in XeLaTeX and LuaLaTeX
Fontspec is a package for XeLaTeX and LuaLaTeX. It provides an automatic and unified interface to feature-rich AAT and OpenType fonts through the NFSS in LaTeX running on XeTeX or LuaTeX engines. The package requires the l3kernel and xparse bundles from the LaTeX 3 development team.
Layout with zero \parindent, non-zero \parskip
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
A Perl script that provides support for thumbnails in pdfTeX and dvips/ps2pdf. The script uses ghostscript to generate the thumbnails which get represented in a TeX readable file that is read by the package thumbpdf.sty to automatically include the thumbnails. This arrangement works with both plain TeX and LaTeX.
The footnote package by Mark Wooding dates back to 1997 and has not been made hyperref compatible. The aim of the present package is to do that.
With the package, \_ in text mode (i.e., \textunderscore) prints an underscore so that hyphenation of words either side of it is not affected; a package option controls whether an actual hyphenation point appears after the underscore, or merely a break point. The package also arranges that, while in text, '_' itself behaves as \textunderscore (the behaviour of _ in maths mode is not affected).
An extensive collection of arithmetic operations for fixed point real numbers of high precision.
Extend the standard classes' size options
Provides classes extarticle, extreport, extletter, extbook and extproc which provide for documents with a base font size from 8-20pt.
Flexible typesetting of table and figure floats using key/value directives
Provides commands to typeset centered, left- or right-aligned table and (multiple-)figure floats, with footnotes. Instead of an environment, a command with 4 arguments is used; the first is optional and is used for key,value pairs generating variations on the defaults and offering a route for future extensions.
The package provides several file hooks (AtBegin, AtEnd, ...) for files read by \input, \include and \InputIfFileExists. General hooks for all such files (e.g. all \include'd ones) and file specific hooks only used for named files are provided; two hooks are provided for the end of \included files -- one before, and one after the final \clearpage.
A simple package to set up document margins
This package is considered obsolete; alternatives are the typearea package from the koma-script bundle, or the geometry package.
Variants of \fbox and other games with boxes
Provides variants of \fbox: \shadowbox, \doublebox, \ovalbox, \Ovalbox, with helpful tools for using box macros and flexible verbatim macros. You can box mathematics, floats, center, flushleft, and flushright, lists, and pages.
This package simplifies the inclusion of external multi-page PDF documents in LaTeX documents. Pages may be freely selected and similar to psnup 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.
The package causes LaTeX to directly produce HTML5 output, using external utility programs only for the final conversion of text and images. Math may be represented by SVG files or MathJax. Documents may be produced by LaTeX, LuaLaTeX, or XeLaTeX. A texlua script removes the need for system utilities such as make and gawk, and also supports xindy and latexmk. Configuration is automatic at the first manual compile. Print and HTML versions of each document may coexist, each with its own set of auxiliary files. Support files are self-generated on request. Assistance is provided for HTML import into EPUB conversion software and word processors.
Typeset fiction, non-fiction and mathematical books
The memoir class is for typesetting poetry, fiction, non- fiction, and mathematical works. Permissible document 'base' font sizes range from 9 to 60pt. There is a range of page- styles and well over a dozen chapter-styles to choose from, as well as methods for specifying your own layouts and designs. The class also provides the functionality of over thirty of the more popular packages, thus simplifying document sources. The class automatically loads an associated patch file mempatch; the patch file may be updated from time to time, between releases of the class itself. (The patch file stays around even when there are no extant patches.) Users who wish to use the hyperref package, in a document written with the memoir class, should also use the memhfixc package (part of this bundle). Note, however, that any current version of hyperref actually loads the package automatically if it detects that it is running under memoir.
Provides support for setting the spacing between lines in a document. Package options include singlespacing, onehalfspacing, and doublespacing. Alternatively the spacing can be changed as required with the \singlespacing, \onehalfspacing, and \doublespacing commands. Other size spacings also available.
The package supports compressed, sorted lists of numerical citations, and also deals with various punctuation and other issues of representation, including comprehensive management of break points. The package is compatible with both hyperref and backref. The package is (unsurprisingly) part of the cite bundle of the author's citation-related packages.
Add picture commands (or backgrounds) to every page
The package adds one or more user commands to LaTeX's shipout routine, which may be used to place the output at fixed positions. The grid option may be used to find the correct places.
The bundle offers versions of the standard LaTeX article and report classes, rewritten to reflect a more European design, and the a4 package, which is better tuned to the shape of a4 paper than is the a4paper class option of the standard classes. The classes include several for article and report requirements, and a letter class. The elements of the bundle were designed by members of the Dutch TeX Users Group NTG.
A LaTeX package for fancy cross-referencing
Provides fancy cross-referencing support, based on the package's reference commands (\fref and \Fref) that recognise what sort of object is being referenced. So, for example, the label for a \section would be expected to be of the form 'sec:foo': the package would recognise the 'sec:' part.
Typeset source code listings using LaTeX
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 (default is bold for keywords, italic for comments and no special style for strings). Support for hyperref is provided. To use, \usepackage{listings}, identify the language of the object to typeset, using a construct like: \lstset{language=Python}, then use environment lstlisting for inline code. External files may be formatted using \lstinputlisting to process a given file in the form appropriate for the current language. Short (in-line) listings are also available, using either \lstinline|...| or |...| (after defining the | token with the \lstMakeShortInline command).
LuaTeX support for pdfTeX utility functions
LuaTeX provides most of the commands of pdfTeX 1.40. However, a number of utility functions are not available. This package tries to fill the gap and implements some of the missing primitives using Lua.
This collection of tools includes: support for short commands starting with @, macros to sanitise the OT1 encoding of the cmtt fonts; a 'do after' 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.
An alternative to babel for XeLaTeX and LuaLaTeX
This package provides a complete Babel replacement for users of LuaLaTeX and XeLaTeX; it relies on the fontspec package, version 2.0 at least. This is the first release that supports use with LuaLaTeX; it should be considered "transitional" in that role.
Adds line numbers to selected paragraphs with reference possible through the LaTeX \ref and \pageref cross reference mechanism. Line numbering may be extended to footnote lines, using the fnlineno package.
This LaTeX package provides a flexible mechanism for translating individual words into different languages. For example, it can be used to translate a word like "figure" into, say, the German word "Abbildung". Such a translation mechanism is useful when the author of some package would like to localize the package such that texts are correctly translated into the language preferred by the user. This package is not intended to be used to automatically translate more than a few words.
Use RCS (revision control system) tags in LaTeX documents
The rcs package utilizes the inclusion of RCS supplied data in LaTeX documents. It's upward compatible to *all* rcs styles I know of. In particular, you can easily access values of every RCS field in your document put the checkin date on the titlepage put RCS fields in a footline You can typeset revision logs. Not in verbatim -- real LaTeX text! But you need a configurable RCS for that. Refer to the user manual for more detailed information. You can also configure the rcs package easily to do special things for any keyword. This bundle comes with a user manual, an internal interface description, full documentation of the implementation, style information for AUC- TeX, and test cases.
The cmap package provides character map tables, which make PDF files generated by pdfLaTeX both searchable and copy-able in acrobat reader and other compliant PDF viewers. Encodings supported are OT1, T1, T2A, T2B, T2C and T5, together with LAE (Arabic), LFE (Farsi) and LGR (Greek) and a variant OT1tt for cmtt-like fonts. The package's main limitation currently is the inability to work with virtual fonts, because of limitations of pdfTeX. This restriction may be resolved in a future version of pdfTeX.
Various LaTeX packages by Martin Schroder
A bundle of LaTeX packages by Martin Schroder; the collection comprises: count1to, make use of fixed TeX counters; everysel, set commands to execute every time a font is selected; everyshi, set commands to execute whenever a page is shipped out; multitoc, typeset the table of contents in multiple columns; prelim2e, mark typeset pages as preliminary; and ragged2e, typeset ragged text and allow hyphenation.
The l3experimental packages are a collection of experimental implementations for aspects of the LaTeX3 kernel, dealing with higher-level ideas such as the Designer Interface. Some of them work as stand alone packages, providing new functionality, and can be used on top of LaTeX2e with no changes to the existing kernel. The present release includes: xgalley, which controls boxes receiving text for typesetting. l3regex: kernel support for regular expression search and replace operations; l3sort: kernel support for sorting sequences, token lists or comma- lists, according to user-specified comparison criteria; l3str: kernel support for string manipulation; l3tl-build: kernel support for token list building; l3tl_analysis: kernel support for token list analysis; and xcoffins, which allows the alignment of boxes using a series of 'handle' positions, supplementing the simple TeX reference point. All the files of the bundle are also available in the Subversion (SVN) repository of the LaTeX3 Project. The bundle on CTAN is based on a snapshot of the SVN repository.
The 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. This package supersedes the subfigure package (which is no longer maintained). The name was changed since the package is completely backward compatible with the older package The major advantage to the new package is that the user interface is keyword/value driven and easier to use. To ease the transition from the subfigure package, the distribution it includes a configuration file (subfig.cfg) which nearly emulates the subfigure package. The functionality of the package is provided by the (more recent still) subcaption package.
The TeX Live software distribution offers a complete TeX system for a variety of Unix, Macintosh, Windows and other platforms. It encompasses programs for editing, typesetting, previewing and printing of TeX documents in many different languages, and a large collection of TeX macros and font libraries. The distribution includes extensive general documentation about TeX, as well as the documentation for the included software packages.
This package exposes spacing parameters for various TeX logos to the end user, to optimise the logos for different fonts. Written especially for XeLaTeX users.
A LaTeX class for producing presentations and slides
The beamer LaTeX class can be used for producing slides. Its functionality is similar to Prosper but does not need any external programs and can directly produce a presentation using pdflatex. Beamer uses pgf for pdf/ps independent graphics. Frames are created using \frame{...}, and a frame can build multiple slides through a simple notation for specifying material for each slide within a frame. Beamer supports bibliographies, appendicies and transitions. Short versions of title, authors, institute can also be specified as optional parameters. A \plainframe{} allows a picture, for example, to fill the whole frame. Support figure and table environments, transparency effects, a \transduration command, animation commands, a pauses environment. Beamer also provides compatibility with other packages like prosper. The package now incorporates the functionality of the former translator package, which is used for customising the package for use in other language environments.
Provides a setup for using the AMS Euler family of fonts for mathematics in LaTeX documents. "The underlying philosophy of Zapf's Euler design was to capture the flavour of mathematics as it might be written by a mathematician with excellent handwriting." The euler package is based on Knuth's macros for the book 'Concrete Mathematics'. The text fonts for the Concrete book are supported by the beton package.
Automatic line breaking of displayed equations
The package provides solutions to a number of common difficulties in writing displayed equations and getting high- quality output. For example, it is a well-known inconvenience that if an equation must be broken into more than one line, 'left...right' constructs cannot span lines. The breqn package makes them work as one would expect whether or not there is an intervening line break. The single most ambitious goal of the package, however, is to support automatic linebreaking of displayed equations. Such linebreaking cannot be done without substantial changes under the hood in the way formulae are processed; the code must be watched carefully, keeping an eye on possible glitches. The bundle also contains the flexisym and mathstyle packages, which are both designated as support for breqn.
Driver-independent color extensions for LaTeX and pdfLaTeX
The package starts from the basic facilities of the color 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. Colors can be mixed like \color{red!30!green!40!blue}.
Generate Unicode characters from accented glyphs
The package supports XeTeX's (and other putative future similar engines') need for Unicode characters, in a similar way to what the fontenc does for 8-bit (and the like) fonts: convert accent- glyph sequence to a single Unicode character for output. The package also covers glyphs specified by packages (such as tipa) which define many commands for single text glyphs.
A class that produces overhead slides (transparencies), with many facilities. The class requires availability of the fancybox package. Seminar is also the basis of other classes, such as prosper. In fact, 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. Note that the seminar distribution relies on the xcomment package, which was once part of the bundle, but now has a separate existence.
Case conversion ignoring mathematics, etc
The textcase package offers commands \MakeTextUppercase and \MakeTextLowercase are similar to the standard \MakeUppercase and \MakeLowercase, but they do not change the case of any sections of mathematics, or the arguments of \cite, \label and \ref commands within the argument. A further command \NoCaseChange does nothing but suppress case change within its argument, so to force uppercase of a section including an environment, one might say: \MakeTextUppercase{...\NoCaseChange{\begin{foo}} ...\NoCaseChange{\end{foo}}...}
The package enhances the quality of tables in LaTeX, providing extra commands as well as behind-the-scenes optimisation. Guidelines are given as to what constitutes a good table in this context. From version 1.61, the package offers longtable compatibility.
Recommended fonts, including the base 35 PostScript fonts, Latin Modern, TeX Gyre, and T1 and other encoding support for Computer Modern, in outline form.
Implementation of the (new in 2015) XeTeX \Ucharcat command in lua, for LuaTeX
The package implements the \Ucharcat command for LuaLaTeX. \Ucharcat is a new primitive in XeTeX, an extension of the existing \Uchar command, that allows the specification of the catcode as well as character code of the character token being constructed.
Complete set of information/warning/error message macros
This package provides a complete set of macros for information, warning and error messages. Under LaTeX, the commands are wrappers for the corresponding LaTeX commands; under Plain TeX they are available as complete implementations.
A package providing corner marks for camera alignment as well as for trimming paper stacks, and additional page information on every page if required. Most macros are easily adaptable to personal preferences. An option is provided for selectively suppressing graphics or text, which may be useful for printing just colour graphics on a colour laser printer and the rest on a cheap mono laser printer. A page info line contains the time and a new cropmarks index and is printed at the top of the page. A configuration command is provided for the info line font. Options for better collaboration with dvips, pdftex and vtex are provided.
The package defines a new math version sans, and a command \sansmath that behaves somewhat like \boldmath
The package offers the command \DeclareFloatingEnvironment, which the user may use to define new floating environments which behave like the LaTeX standard foating environments figure and table.
Flexible handling of verbatim text including: verbatim commands in footnotes; a variety of verbatim environments with many parameters; ability to define new customized verbatim environments; save and restore verbatim text and environments; write and read files in verbatim mode; build "example" environments (showing both result and verbatim source).
Improves the interface for defining floating objects such as figures and tables. Introduces the boxed float, the ruled float and the plaintop float. You can define your own floats and improve the behaviour of the old ones. The package also provides the H float modifier option of the obsolete here package. You can select this as automatic default with \floatplacement{figure}{H}.
Mathtools provides a series of packages designed to enhance the appearance of documents containing a lot of mathematics. The main backbone is amsmath, so those unfamiliar with this required part of the LaTeX system will probably not find the packages very useful. Mathtools provides many useful tools for mathematical typesetting. It is based on amsmath and fixes various deficiencies of amsmath and standard LaTeX. It provides: Extensible symbols, such as brackets, arrows, harpoons, etc.; Various symbols such as \coloneqq (:=); Easy creation of new tag forms; Showing equation numbers only for referenced equations; Extensible arrows, harpoons and hookarrows; Starred versions of the amsmath matrix environments for specifying the column alignment; More building blocks: multlined, cases-like environments, new gathered environments; Maths versions of \makebox, \llap, \rlap etc.; Cramped math styles; and more... Mathtools requires mhsetup.
Alternative versions of "ragged"-type commands
The package defines new commands \Centering, \RaggedLeft, and \RaggedRight and new environments Center, FlushLeft, and FlushRight, which set ragged text and are easily configurable to allow hyphenation (the corresponding commands in LaTeX, all of whose names are lower-case, prevent hyphenation altogether).
This package is an extension of the keyval package and offers additional macros for setting keys and declaring and setting class or package options. The package allows the programmer to specify a prefix to the name of the macros it defines for keys, and to define families of key definitions; these all help use in documents where several packages define their own sets of keys.
Miscellaneous macros by Jorg Knappen, including: represent counters in greek; Maxwell's non-commutative division; latin1jk, latin2jk and latin3jk, which are their 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.
