The package allows LaTeX maths users of the PX fonts to select the shapes (italic or upright) for the Greek lowercase and uppercase letters. Once the shapes for lowercase and uppercase have been selected via a package option, the \other prefix (e.g., \otheralpha) allows using the alternate glyph (as in the fourier package). The pxgreeks package does not constrain the text font that may be used in the document.

The package provides commands for splitting a token list at the first occurrence of another (specified) token list. The package's mechanism differs from those of packages providing similar features, in the following ways: the method uses TeX's mechanism of reading delimited macro parameters; splitting macros work by pure expansion, without assignments; the operation is carried out in a single macro call. A variant of the operation is provided, that retains outer braces.

The package allows LaTeX users who use the TX fonts to select the shapes (italic or upright) for the Greek lowercase and uppercase letters. Once the shapes for lowercase and uppercase have been selected via a package option, the \other prefix (e.g., \otheralpha) allows using the alternate glyph (as in the fourier package). The txgreeks package does not constrain the text font that may be used in the document.

Epstopdf is a Perl script that converts an EPS file to an encapsulated PDF file (a single page file whose media box is the same as the original EPS's bounding box). The resulting file suitable for inclusion by pdfTeX as an image. LaTeX users may make use of the epstopdf package, which will run the epstopdf script on the fly, thus giving the illusion that pdfLaTeX is accepting EPS graphic files.

Virtual font metrics are usually created in a textual form, the Virtual Property List, but programs that use them need to use binary files (the Virtual Font and the TeX Font Metric). The two programs provided in this package translate between the two forms: vptovf takes a VPL file and generates a VF file and a TFM file; vftovp takes a VF file and a TFM file and generates a VPL file.

optional provides simple, flexible, optional compilation of LaTeX documents. Option switches may be given via package options, by the \UseOption command, or interactively via the \AskOption command (help text may be provided, by defining the \ExplainOptions command). The package is not robust, in the way that comment package is, against ill-behaved text. In particular, verbatim text may not be directly included in optional sections (whether they're included or not).

TeXlogos defines an assortment of frequently used logos not contained in base LaTeX itself. The Metafont, MetapostAMS, BibTeX and SliTeX logos are defined, as long as you have the appropriate CM/Logo/AMS fonts. Currency symbols Euro, Cent, Yen, Won and Naira are defined so as not to need TS1-encoded fonts. Also defined are the C++ logo, with the + signs properly positioned, and the logo of the Vienna University Business Administration Center (BWZ).

The package provides four commands for vertically scaling and stretching objects. Its primary function is the ability to scale/stretch and shift one object to conform to the size of a specified second object. This feature can be useful in both equations and schematic diagrams. Additionally, the scaling and stretching commands offer constraints on maximum width and/or minimum aspect ratio, which are often used to preserve legibility or for the sake of general appearance.

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.

The nef TikZ library provides predefined styles and shapes to create diagrams for neural networks constructed with the methods of the Neural Engineering Framework (NEF). The following styles are supported:

• ea: ensemble array,

• ens: ensemble,

• ext: external input or output,

• inhibt: inhibitory connection,

• net: network,

• pnode: pass-through node,

• rect: rectification ensemble,

• recurrent: recurrent connection.

This package provides macros for processing a CSV spreadsheet file with a minimum of configuration for the CSV file. The first row names the columns and the remaining rows are data. This data can be merged with TeX code residing in an auxiliary file and the process repeated for each data row. There is one macro to set things up, one to extract the data, and one to tell if the field is empty or not.

This package provides several document level commands to ease typesetting of maths with LaTeX. It provides complementary commands to all operators defined by amsmath that typeset the operators together with delimiters. These commands also accept optional sub- and superscripts. Additionally, this package provides several commands to typeset gradient, divergence, curl, Laplace, and d'Alembert operators. Furthermore several commands for producing row and column vectors, as well as (anti-)diagonal matrices and identity matrices are provided.

TeXplate is a tool for creating document structures based on templates. The application name is a word play on TeX and template, so the purpose seems quite obvious: we want to provide an easy and straightforward framework for reducing the typical code boilerplate when writing TeX documents. Also note that one can easily extrapolate the use beyond articles and theses: the application is powerful enough to generate any text-based structure, given that a corresponding template exists.

The package lets you shade or colour the cells in the alignment environments such as \halign and LaTeX's tabular and array environments. The colortbl package is to be preferred today with LaTeX (it assures compatibility with the longtable package, which is no longer true with colortab); another modern option is the table-colouring option of the xcolor. However, colortab remains an adequate solution for use with Plain TeX.

The package deals with the behaviour of the LaTeX internal command \@ifnextchar, which skips blank spaces. This has the potential to surprise users, since it can produce really unwanted effects. A common example occurs with brackets starting a line following \\: the command looks for an optional argument, whereas the user wants the brackets to be printed. The package offers commands and options for modifying this behaviour, maybe limited to certain parts of the document source.

The ffslides (``freeform slides'') class is intended to make it easier to place various types of content freely on the page, and therefore easier to design documents with a strong visual component: presentations, posters, research or lecture notes, and so on. The goal of the class is to be less rigid and less complex than some of the popular presentation-making options. It is essentially a small set of macros added to the article class.

The package defines commands for saving content that can be repeatedly placed into the document without replicating DVI/PDF code in the output file, allowing for smaller file size of the final PDF and improved content caching for faster display in certain PDF viewers. The method makes use of Form XObjects defined in the PDF specification. The user commands are modelled after the standard LaTeX commands \savebox, \sbox, \usebox and the lrbox environment.

This package enables the typesetting of formalized legal documents such as contracts, statutes etc. It will be the successor to the scrjura package. Like the latter, contract allows the typographically appealing typesetting of many different legal texts. The typesetting of contracts according to German conventions is supported out of the box. In addition, the package supports the definition of custom environments in order to typeset contracts and legal texts according to Anglo-American specifications, for example.

The package provides functionality for processing lists and array structures in LaTeX. Arrays can contain characters as well as TeX and LaTeX commands, nesting of arrays is possible, and arrays are processed within the same brace level as their surrounding environment. Array levels can be delimited by characters or control sequences defined by the user. Practical uses of this package include data management, construction of lists and tables, and calculations based on the contents of lists and arrays.

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.

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. 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.

TeXPower is a bundle of packages intended to provide an all-inclusive environment for designing pdf screen presentations to be viewed in full-screen mode, especially for projecting online with a video beamer. For some of its core functions, it uses code derived from ppower4 packages. It is, however, not a complete environment in itself: it relies on an existing class for preparing slides (such as foiltex or seminar) or another package such as pdfslide.

The float package provides commands to define new floats of various styles (plain, boxed, ruled, and userdefined ones); the rotating package provides new environments (sidewaysfigure and sidewaystable) which are rotated by 90 or 270 degrees. But what about new rotated floats, e.g., a rotated ruled one? This package makes this possible; it builds a bridge between the two packages and extends the commands from the float package to define rotated versions of the new floats, too.

This package provides Concrete Roman fonts, designed by Donald Knuth, originally for use with Euler mathematics fonts. Alternative mathematics fonts, based on the concrete parameter set are available as the concmath fonts bundle. LaTeX support is offered by the beton, concmath and ccfonts packages. T1- and TS1-encoded versions of the fonts are available in the ecc bundle, and Adobe Type 1 versions of the ecc fonts are part of the cm-super bundle.
