LaTeX's standard styles use two page styles, one on normal pages and one on opening pages with \maketitle or \chapter, etc. Unfortunately there is only easy access to changing one of these two so if you want something other than plain on the opening pages you must use \thispagestyle on each such page. The fancyhdr package does provide a more flexible interface, but if you just want an empty page style on all pages then this package will do the job.

pdftosrc extracts an embedded source file, or extracts and uncompresses a PDF stream given by object number.

This package can be used to include every kind of Scratch program in LaTeX documents. This may be particularly useful for Math Teachers and IT specialists.

The lgrmath package is a LaTeX package which sets the Greek letters in math mode to use glyphs from the LGR-encoded font of one's choice. The documentation includes a rather extensive list of the available font family names on typical LaTeX installations.

This package provides a jiffy file (taken from fancybox) for placing a frame around a box of text. The macros also provide for typesetting an empty box of given dimensions.

Diagxy is a general diagramming package, useful for diagrams in a number of mathematical disciplines.

The package provides a command \isotope for setting the atomic weight and atomic number indications of isotopes.

Nature does not accept papers in LaTeX, but it does accept PDF. This class and BibTeX style provide what seems to be necessary to produce papers in a format acceptable to the publisher.

This package provides Czech/Slovak-tuned Computer Modern fonts in the Metafont format; Type 1 format versions (csfonts-t1) are also available.

The purpose of this package is to extend TikZ with the functionality for drawing quantum circuit diagrams.

This is a bundle of Lua scripts and LaTeX packages for conversion of LaTeX files to EBook formats such as EPUB, MOBI and EPUB3. TeX4ht is used as the conversion engine.

pst-lsystem is a PSTricks based package for creating images based on a L-system. A L-system (Lindenmayer system) is a set of rules which can be used to model the morphology of a variety of organisms or fractals like the Kochflake or Hilbert curve.

The package enables you to embed Python code in LaTeX, and insert the script's output in the document.

The package is used in documentation files; with it the code listings will highlight (for example) pairs of curly braces with matching colors. Other delimiters like \if ... \fi, are highlighted, as are the names of new commands. All this makes code a little more readable, and helps during process of writing. Three options are provided, including a non-color option designed for printing (which numbers delimiters and underlines new commands).

This package provides an abstraction for creating PRISMA 2009 flow diagrams in LaTeX. It simplifies the process of building these diagrams by providing intuitive commands while maintaining full compatibility with TikZ.

This package provides a Lua script which can be used for retrieving bibliographic information in BibLaTeX format for packages hosted on CTAN. The ctanbib script depends only on LuaXML.

This is a simple wrapper for the paracol package for setting two-column parallel text.

The package provides an expandable variant of the LaTeX kernel command \@testopt, named \@expandable@testopt, and a more general \@expandable@ifopt, both intended for package writers. Also we have a variant of \newcommand which uses these macros to check for optional arguments.

The class offers another modern, neat, design, and provides a simple means of adding an experience timeline'.

The gauss package provides configurable tools for producing row and column operations on matrices (a.k.a.: Gaussian operations).

This package contains templates for the creation of documents for IARIA publications (International Academy, Research, and Industry Association) and implements the specifications for the IARIA citation style.

The bundle deals with category code switching; the packages of the bundle should work with any TeX format (with the support of the plainpkg package). The bundle provides:

• stacklet.sty, which supports stacks that control the use of different catcodes;

• actcodes.sty, which deals with active characters;

• catchdq.sty, which provides a simple quotation character control mechanism.

This package supports common layouts for tabular column heads in whole documents, based on one-column tabular environment. In addition, it can create multi-lined tabular cells.

The package also offers:

• a macro which changes the vertical space around all the cells in a tabular environment,

• macros for multirow cells, which use the facilities of the multirow package,

• macros to number rows in tables, or to skip cells;

• diagonally divided cells;

• horizontal lines in tabular environments with defined thickness.

The package provides a counter style (like \arabic, \alph and others) which produces output strings like primeiro (``first'' in Portuguese), segundo, (``second''), and so on up to 1999th. Separate counter commands are provided for different letter case variants, and for masculine and feminine gender inflections.
