The package provides macros for typesetting math formulas in mixed horizontal and vertical mode, automatically as best fit. It provides an environment mathpar that behaves much as a loose centered paragraph where words are math formulas, and spaces between them are larger and adjustable. It also provides a macro \inferrule for typesetting fractions where both the numerator and denominator may be sequences of formulas that will be also typeset in a similar way. It can typically be used for typeseting sets of type inference rules or typing derivations.

The pagelayout class enables you to layout pages declaratively using simple macros for pages, covers, grids, templates, text, and graphics to create graphic rich, perfectly typeset, and print ready PDFs. The integration of Inkscape allows your to create box shadows. The integration of ImageMagick allows you to configure compression and sharpening for bitmap graphics to export web, print or preview versions of your document. Parallelized image optimization, caching, and a draft mode enable fast PDF creation and a responsive workflow, even for large documents with lots of photos and graphics.

This package provides several tools that aim to simplify the compilation of LaTeX documents:

• LaTeX.mk: a Makefile snippet to help compiling LaTeX documents in DVI, PDF, PS, ... format. Dependencies are automatically tracked: one should be able to compile documents with a one-line Makefile containing include LaTeX.mk. Complex documents (with multiple bibliographies, indexes, glossaries, ...) should be correctly managed.

• figlatex.sty: a LaTeX package to easily insert Xfig figures. It can interact with LaTeX.mk so that the latter automatically invokes fig2dev if needed.

This package is meant for content which you reuse regularly, like songs in small booklets. For example the booklets used at church, weddings or similar events. You typeset your content once (most likely a song), garnish it with some meta data and put it into a file. From there you can insert this content into your document with one single line. The inserted content can have header and footer that use the meta data (i.e., title, composer, lyricist). Inside these content fragments, you can combine an image of a stave line with song lyrics.

The PDF visualizer http://issuu.com/ISSUU is a popular service which shows PDF documents ``a page a time''. Due to the way it is implemented, internal links in these documents are not allowed. Instead, they must be converted to external ones in the form http://issuu.com/action/page?page=PAGENUMBER. The package patches hyperref to produce external links in the required form instead of internal links created by \ref, \cite and other commands.

Since the package redefines the internals of hyperref, it must be loaded after hyperref.

The statistics package can compute and typeset statistics like frequency tables, cumulative distribution functions (increasing or decreasing, in frequency or absolute count domain), from the counts of individual values, or ranges, or even the raw value list with repetitions. It can also compute and draw a bar diagram in case of individual values, or, when the data repartition is known from ranges, an histogram or the continuous cumulative distribution function. You can ask statistics to display no result, selective results or all of them. Similarly statistics can draw only some parts of the graphs.

The package uses a text font (usually the document's text font) for the letters of the Latin alphabet needed when typesetting mathematics. (Optionally, other characters in the font may also be used). This facility makes possible (for a document with simple mathematics) a far wider choice of text font, with little worry that no specially designed accompanying maths fonts are available. The package also offers a simple mechanism for using many different choices of (text hence, now, maths) font in the same document. Of course, using one font for two purposes helps produce smaller PDF files.

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.

Montserrat is a geometric sans-serif typeface designed by Julieta Ulanovsky. It is rather close in spirit to Gotham and Proxima Nova, but has its own individual appearance --- more informal, less extended, and more idiosyncratic. It is provided in a total of nine different weights, each having eight figure styles and small caps in both upright and italic shapes. There are two quite different versions that don't fit into the usual LaTeX classifications. The version having the appellation Alternates has letter shapes that are much more rounded than the default version, reflecting the signage in the neighborhood of Montserrat.

Romande ADF is a serif font family with oldstyle figures, designed as a substitute for Times, Tiffany or Caslon. The family currently includes upright, italic and small-caps shapes in each of regular and demi-bold weights and an italic script in regular. The support package renames the fonts according to the Karl Berry font name scheme and defines four families. Two of these primarily provide access to the ``standard'' or default characters while the ``alternate'' families support alternate characters, additional ligatures and the long ``s''. The included package files provide access to these features in LaTeX as explained in the documentation.

This LuaLaTeX package provides extensive support for handling options, on package level and locally. It allows the declaration of sets of options, along with defaults, allowed values and limited type checking. These options can be enforced as package options, changed at any point during a document, or overwritten locally by optional macro arguments. It is also possible to instantiate an Options object as an independent Lua object, without linking it to a package. Luaoptions can be used to enforce and prepopulate options, or it can be used to simply handle the parsing of optional key=value arguments into proper Lua tables.

This package defines the command \perfectcut#1#2 which displays a bracket <#1||#2>. Various other delimiters are similarly defined (parentheses, square brackets ...). The effect of these commands is to let the delimiters grow according to the number of nested \perfectcommands (regardless of the size of the contents).

The package was originally intended for solving a notational issue for direct-style continuation calculi in proof theory. For general use, the package also defines commands for defining other sorts of delimiters which will behave in the same way. The package also offers a robust reimplementation of \big, \bigg, etc.

Many people preparing their resumes find the requirement ``please list five (or six, or ten) papers authored by you''. The same requirement is often stated for reports prepared by professional teams. The creation of such lists may be a cumbersome task. Even more difficult is it to support such lists over the time, when new papers are added. The BibTeX style bestpapers.bst is intended to facilitate this task. It is based on the idea that it is easier to score than to sort: we can assign a score to a paper and then let the computer select the papers with highest scores.

This program can be used to automate the upload of a package to CTAN. The description of the package is contained in a configuration file. The provided information is validated in any case. If the validation succeeds and not only the validation is requested, then the provided archive file will be placed in the incoming area of the CTAN for further processing by the CTAN team. In any case any finding during the validation is reported at the end of the processing. Note that the validation is the default and an official submission has to be requested by an appropriate command line option.

In colorblind-safe documents, the contents are presented in a way that the same information is conveyed to readers regardless of a potential color vision deficiency. This package provides the tools necessary for colorblind-safe typesetting in LaTeX. It provides color schemes for a wide range of applications. The most commonly used schemes are qualitative schemes, providing easily distinguishable colors for use in graphics, but also for text coloring or highlighting. Additionally, diverging and sequential schemes are included which can be used for encoding quantitative information using colors. This package incorporates colorblind-safeness into the writing process, making it both less cumbersome and less error-prone.

This bundle provides a class examdesign. The class provides several features useful for designing tests or question sets: it allows for explicit markup of questions and answers; the class will, at the user's request, automatically generate answer keys; multiple versions of the same test can be generated automatically, with the ordering of questions within each section randomly permuted so as to minimize cheating; the generated answer keys can be constructed either with or without the questions included; environments are provided to assist in constructing the most common types of test question: matching, true/false, multiple-choice, fill-in-the-blank, and short answer/essay questions.

The package provides macros to collect and process a macro argument (i.e., something which looks like a macro argument) as a horizontal box rather than as a real macro argument. The "arguments" are stored as if they had been saved by \savebox or by the lrbox environment. Grouping tokens \bgroup and \egroup may be used, which allows the user to have the beginning and end of a group in different macro invocations, or to place them in the begin and end code of an environment. Arguments may contain verbatim material or other special use of characters. The macros were designed for use within other macros.

This package provides an user interface for making LaTeX cross-references flexibly, while allowing to have them checked for consistency with the document structure as typeset. Statements such as above, on the next page, previously, can be given to \zcheck in free-form, and a set of checks can be specified to be run against a given label, which will result in a warning at compilation time if any of these checks fail. \zctarget and the zcregion environment are also defined as a means to easily set label targets to arbitrary places in the text which can be referred to by \zcheck.

This package aims to improve of font readability in presentations, especially with maths. The standard CM maths fonts at large design sizes are difficult to read from far away, especially at low resolutions and low contrast color choice. Using this package leads to much better overall readability of some font combinations. The package offers a couple of harmonising combinations of text and maths fonts from the (distant) relatives of Computer Modern fonts, with a couple of extras for optimising readability. Text fonts from Computer Modern roman, Computer Modern sans serif, SliTeX Computer Modern sans serif, Computer Modern Bright, or Concrete Roman are available, in addition to maths fonts from Computer Modern maths, Computer Modern Bright maths, or Euler fonts.

This package provides for LuaLaTeX an ArabTeX-like interface to generate Arabic writing from an ascii transliteration. It is particularly well-suited for complex documents such as technical documents or critical editions where a lot of left-to-right commands intertwine with Arabic writing. arabluatex is able to process any ArabTeX input notation. Its output can be set in the same modes of vocalization as ArabTeX, or in different roman transliterations. It further allows many typographical refinements. It will eventually interact with some other packages yet to come to produce from .tex source files, in addition to printed books, TEI XML compliant critical editions and/or lexicons that can be searched, analyzed and correlated in various ways.

LaTeX tables are implemented using TeX commands such as \halign, \noalign, \span, and \omit. In order to implement new features, many macro packages have modified the inner table commands inside LaTeX. This makes package code complicated, difficult to maintain, and often conflicts with each other. At present, the LaTeX3 programming layer is basically mature. This tabularray package will discard the old \halign commands and directly use LaTeX3 functions to parse the table, and then typeset the entire table. Under the premise of being compatible with the basic syntax of LaTeX2 tables, this macro package will completely separate the content and style of the table, and the style of the table can be completely set in keyval way.

This collection comprises a set of four manuals, or Author Handbooks, each documenting the use of a class of publications based on one of the AMS document classes amsart, amsbook, amsproc and one hybrid, as well as a guide to the generation of the four manuals from a coordinated set of LaTeX source files. The Handbooks comprise the user documentation for the pertinent document classes. As the source for the Handbooks consists of a large number of files, and the intended output is multiple different documents, the principles underlying this collection can be used as a model for similar projects. The manual Compiling the AMS Author Handbooks provides information about the structure of and interaction between the various components.

The greektonoi mapping extends the betababel package or the Babel polutonikogreek option to provide a simple way to insert ancient Greek texts with diacritical characters into your document using a similar method to the commonly used Beta Code transliteration, but with much more freedom. It is designed especially for the XeTeX engine and it could also be used for fast and easy modification of monotonic Greek texts to polytonic. The output text is natively encoded in Unicode, so it can be reused in any possible way. The greektonoi package provides, in addition to inserting Greek accents and breathings, many other symbols used in Greek numbers and arithmetic or in the Greek archaic period. It could be used with greektonoi mapping or independently.

This collection contains implementations for aspects of the LaTeX3 kernel, dealing with higher-level ideas such as the Designer Interface. The packages here are considered broadly stable (The LaTeX3 Project does not expect the interfaces to alter radically). These packages are built on LaTeX2e conventions at the interface level, and so may not migrate in the current form to a stand-alone LaTeX3 format.

Packages provided are xparse, which provides a high-level interface for declaring document commands xfp, an expandable IEEE 754 FPU for LaTeX, l3keys2e, which makes the facilities of the kernel module l3keys available for use by LaTeX 2e packages, xtemplate, which provides a means of defining generic functions using a key-value syntax, and xfrac, which provides flexible split-level fractions.
