With this template, and associated style and LaTeX packages, it is possible to estimate the page length of manuscripts for submission to the SPIE journals Optical Engineering and Optical Engineering Letters. With a strict three-page limit, this is particularly important for the latter. The template gives simple instructions on how to prepare the manuscript.

This is a BibLaTeX style that implements the bibliography style of the Council of Science Editors (CSE) for BibLaTeX.

Plnfss is a set of macros to provide easy font access (somewhat similar to NFSS but with some limitations) with Plain TeX. Plnfss can automatically make use of PSNFSS fd files, i.e., when an Adobe Type 1 is used the relevant fd file will be loaded automatically. For cmr-like fonts (ec, vnr, csr or plr fonts), a special format called pfd (plain fd) is required and must be loaded manually.

This package provides a macro to set various margins as well as dimensions for header/footer and page dimensions. Most common paper sizes, paper orientation, disabling of headers and footers, and two sided printing are supported.

The user interface might not be very fancy, but it's fast, small, and gets the job done. If you are looking for something more elaborate try the geometry package.

This package is for including .Rnw (knitr/sweave) files inside .tex files. It requires that you have R and the R-package knitr installed.

The sidecap package defines environments called SCfigure and SCtable (analogous to figure and table) to typeset captions sideways. Options include outercaption, innercaption, leftcaption and rightcaption.

This package provides OpenType math font support in plain TeX format. It only works with the XeTeX engine.

The package provides two commands: \dotlessi and \dotlessj, which give access to dotless i and j in math mode. They are intended for symbols in non English languages.

The package provides helpers for German language package documentation.

This is a modern plain format for the LuaTeX engine, adding improved low-level support for many LuaTeX extensions and newer PDF features. While it can be used as drop-in replacement for plain TeX, it probably is most useful as a basis for your own formats. Most features included in the format are provided by separate packages that can be used on their own; this package contains only their shared lowest-level programming interface, along with their combined format.

This package provides commands to draw scientific calculator keys with the help of TikZ. It also provides commands to draw the content of screens and of menu items.

This collection provides support packages for German.

This package provides environments for hanging paragraphs and list items. In addition, it defines environments for labeled paragraphs and list items.

This package provides miscellaneous LaTeX packages and classes.

The \maybebm and \maybeit macros can be used in maths expressions to make the arguments typeset as bold or italic respectively if the surrounding context is appropriate. They are useful for writing user macros for use in general contexts. \maybebm is especially appropriate when section titles contain math expressions, since the title will appear bold but the header and table of contents usually replicate the title in normal width. \maybeit performs a similar role to \mathrm but the maths expression will be italicised if the surrounding text is. \maybeitsubscript is provided to shift subscripts to the left if the expression is italicised.

This package provides environments randbild to draw small marginal plots (using the packages PSTricks and pst-plot), and randbildbasis (the same, only without the automatically drawn coordinate system).

The kastrup package provides the binhex.tex file. This file provides expandable macros for both fixed-width and minimum-width numbers to bases 2, 4, 8 and 16. All constructs TeX accepts as arguments to its \number primitive are valid as arguments for the macros. The package may be used under LaTeX and plain TeX.

The datetime2 package provides commands for formatting dates, times and time zones and redefines \today to use the same formatting style. In addition to \today, you can also use \DTMcurrenttime (current time) or \DTMnow (current date and time). Dates and times can be saved for later use. The accompanying datetime2-calc package can be used to convert date-times to UTC+00:00. Language and regional support is provided by independently maintained and installed modules. The datetime2-calc package uses the pgfcalendar package (part of the PGF/TikZ bundle). This package replaces datetime.sty, which is now obsolete.

This package is an extension to the exam document class. It provides the user with four new multiple choice typesetting environments which place their content in a random order. It can (only) be used in combination with the exam class. The questions themselves cannot be randomized with this package. Furthermore, the package provides a simple answer key table typesetter and has a command for writing the answer keys to an external file.

This package provides a citation and bibliography style for use with BibLaTeX. It conforms to the bibliographic standards used at the Ecole nationale des chartes (Paris), and may be suitable for a more general use in historical and philological works.

This package calculates biological sequence alignment with the Gotoh algorithm. The package also provides an interface to control various settings including algorithm parameters.

Following the lead of xii.tex, this little program plays Reversi.

Lua code working with Unicode data has to deal with quite some challenges. For example there are many canonically equivalent sequences which should be treated in the same way, and even identifying a single character becomes quite different once you have to deal with all kinds of combining characters, emoji sequences and syllables in different scripts. Therefore lua-uni-algos wants to build a collection of small libraries implementing algorithms to deal with lots of the details in Unicode, such that authors of LuaTeX packages can focus on their actual functionality instead of having to fight against the peculiarities of Unicode. Given that this package provides Lua modules, it is only useful in Lua(HB)TeX. Additionally, it expects an up-to-date version of the unicode-data package to be present. This package is intended for package authors only; no user-level functionality provided.

This collection contains files to add wallpapers (background images) to LaTeX documents. It provides simple commands to include effects such as tiling.
