The package aids spell-checking of TeX documents compiled with the LuaTeX engine. It can give visual feedback in PDF output similar to WYSIWYG word processors. The package relies on an external spell-checker application to check spelling of a text file and to output a list of bad spellings. The package should work with most spell-checkers, even dumb, TeX-unaware ones.

This package puts a grid on the paper. It was written for developers of a class or package who have to put elements on definite locations on a page (e.g., letter class). The grid allows a faster optical check, whether the positions are correct. If the previewer already offers features for measuring, the package might be unnecessary. Otherwise it saves the developer from printing the page and measuring by hand.

Cabin is a humanist sans with four weights and true italics and small capitals. According to the designer, Pablo Impallari, Cabin was inspired by Edward Johnston's and Eric Gill's typefaces, with a touch of modernism. Cabin incorporates modern proportions, optical adjustments, and some elements of the geometric sans. cabin.sty supports use of the font under LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX; it uses the mweights, to manage the user's view of all those font weights. An option is provided to enable Cabin as the default text font.

There are macro and environment arguments that expect numbers that will internally be multiplied by \unitlength. This package extends the syntax of these arguments, so that dimensions with calculation support may be used for these arguments.

This package provides LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX support for the Marcellus family of fonts, designed by Brian J. Bonislawsky. Marcellus is a flared-serif family, inspired by classic Roman inscription letterforms. There is currently just a regular weight and small-caps. The regular weight will be silently substituted for bold.

The T2 bundle provides a variety of separate support functions for using Cyrillic characters in LaTeX:

• the mathtext package, for using Cyrillic letters transparently in formulae;

• the citehack package, for using Cyrillic (or indeed any non-ASCII) characters in citation keys;

• support for Cyrillic in BibTeX;

• support for Cyrillic in Makeindex;

• and various items of font support.

This module provides the samin style that can be set using \DTMsetstyle provided by datetime2.sty. This package is currently unmaintained.

Semantic Web resource URLs are often abbreviated with prefixes, like owl:Class or rdf:type. The abbreviated URL (aurl) package provides the correct hyperlinks for those URLs. The 1000 most common prefixes are predefined and more can be added.

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

This package facilitates the use of fontspec for users who do not wish to bother with details, with a special focus on quality fonts supporting mathematics.

This package replaces \textsuperscript and \textsubscript commands by equivalent commands that use OpenType font features to access appropriate glyphs if possible. It also patches LaTeX's default footnote command to use this new \textsuperscript for footnote symbols.

This TikZ library is designed for generating diagrams related to Automated Planning, a sub-discipline of Artificial Intelligence. It allows users to define a ``domain model'' for actions, similar to PDDL and HDDL used in hierarchical planning. The package is useful for researchers and students to create diagrams that represent sequential action sequences or partially ordered plans, including causal links and ordering constraints (e.g., POCL plans). It is particularly suited for presentations and scientific publications.

This package provides a LaTeX interface to create, modify, and use the Lua data structure tables. Lua tables can be declared with the help of luakeys, and this package provides facilities to set, get, check, iterate, apply, etc., to the table.

The package integrates the features of xkeyval and of pgfkeys by introducing a new type of handlers. Style keys, links, changing key callbacks and values on the fly, and other features of pgfkeys are introduced in a new context.

The GFSNeohellenic font, a historic font first designed by Victor Scholderer, now has native support for Mathematics. A useful application is in Beamer documents since this is a sans math font.

The package is an update of the author's sseq package, for use with LuaLaTeX. This version uses less memory, and operates faster than the original; it also offers several enhancements.

This package provides an easy way to input slides on note pages quickly.

The family contains text fonts in roman, sans-serif and monospaced shapes, with true small caps and old-style numbers; the package offers full support of the textcomp package. The mathematics fonts include all the AMS fonts, in both normal and bold weights. Each of the font types is available in two main versions: default and light. Each version is available in four variants: default; oldstyle numbers; oldstyle numbers with old ligatures such as ct and st, and long-tailed capital Q; and veryoldstyle with long s. Other variants include small caps as default or large small caps, and for mathematics both upright and slanted shapes for Greek letters, as well as default and narrow versions of multiple integrals.

The package addresses, for LaTeX documents, the severe limitation on the number of output streams that TeX provides. The package uses a single TeX output stream, and writes marked-up output to this stream. The user may then post-process the marked-up output file, using LaTeX, and the document's output appears as separate files, according to the calls made to the package. The output to be post-processed uses macros from the widely-available ProTeX package.

The package provides macros \DeclareRobustActChar and \ReDeclareRobActChar. One uses \DeclareRobustActChar in the same way one would use \DeclareRobustCommand; the macro \protects the active character when it appears in a moving argument. \ReDeclareRobActChar redefines an active character previously defined with \DeclareRobustActChar, in the same way that \renewcommand works for ordinary commands.

Apacite provides a BibTeX style and a LaTeX package which are designed to match the requirements of the American Psychological Association's style for citations. The package follows the 6th edition of the APA manual, and is designed to work with the apa6 class.

Epigraphs are the pithy quotations often found at the start (or end) of a chapter. Both single epigraphs and lists of epigraphs are catered for. Various aspects are easily configurable.

The package allows the user to define shorthand aliases for single Unicode characters, and also provides support for such aliases in RTL-text. The package requires an TeX-alike system that uses Unicode input in a native way: current examples are XeTeX and LuaTeX.

This is a book publishing scheme, containing core (Lua)LaTeX and selected additional packages likely to be useful for non-technical book publication. It does not contain additional fonts (different books need different fonts, and the packages are large), nor does it contain additional mathematical or other technical packages.
