This package is based on the package TikZ and can be used to draw polyominoes. It is possible to define custom styles, pics and grids.

The hfoldsty package provides virtual fonts for using old-style figures with the European Computer Modern fonts. It does a similar job as the eco package but includes a couple of improvements, i.e., better kerning with guillemets, and support for character protruding using the pdfcprot package.

This package is based on code to equalise the height of subscripts in maths. The default behaviour is to place subscripts slightly lower when there is a superscript as well, but this can look odd in some situations.

This package allows you to create lists of numbered items with a single active character as the only command. A variety of parameters are available to configure the appearance of the list; lists may be nested (effectively to unlimited depth).

ekdosis is a LuaLaTeX package designed for multilingual critical editions. It can be used to typeset texts and different layers of critical notes in any direction accepted by LuaTeX. Texts can be arranged in running paragraphs or on facing pages, in any number of columns which in turn can be synchronized or not. In addition to printed texts, ekdosis can convert .tex source files so as to produce TEI XML-compliant critical editions. Database-driven encoding under LaTeX then allows extraction of texts entered segment by segment according to various criteria: main edited text, variant readings, translations or annotated borrowings between texts.

This package provides macros beginning with the PS character, made active, which enable us to write the British or American English pronunciation as one can find it in the English Pronouncing Dictionary by Daniel Jones. There is an option to typeset the pronunciation in the style of Harrap's dictionary.

This package offers a way to find keys in a given path recursively, unlike pgfkeysvalueof.

This is a complete and easy-to-use package for typesetting pretty tables of signs and variations according to French usage. The syntax is similar to that of the array environment and uses intuitive position commands. Arrows are drawn automatically (using PSTricks by default or TikZ as an option). Macros are provided for drawing twin bars, single bars crossing the zeros, areas where the function is not defined, or placing special values. Several features of the variation tables can be customized.

This package will introduce the operations related to installing TeX Live and mainly introducing command line operations, in Chinese.

The bundle comprises: authblk, which permits footnote style author/affiliation input in the \author command, balance, to balance the end of \twocolumn pages, figcaps, to send figure captions, etc., to end document, fullpage, to set narrow page margins and set a fixed page style, and sublabel, which permits counters to be subnumbered.

The package defines a graph data structure, for use in documents that are using the experimental LaTeX 3 syntax.

The calculation environment formats reasoned calculations, also called calculational proofs. The package allows steps and expressions to be numbered (by LaTeX equation numbers, obeying the LaTeX \label command to refer to these numbers), and a step doesn't take vertical space if its hint is empty. An expression in a calculation can be given a comment; it is placed at the side opposite to the equation numbers. Calculations are allowed inside hints although numbering and commenting is then disabled.

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 fallback CJK font support for xeCJK.

The class offers entries for assets and social networks; customizable styles are provided. The class comes with no documentation, but a worked example offers some guidance.

The package offers enhancements for theorem-like environments: easier control of layout; proper placement of endmarks even when the environment ends with \end{enumerate} or \end{displaymath} (including support for amsmath displayed-equation environments); and support for making a list of theorems, analogous to \listoffigures.

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.

These are font bundles for the Chinese Arphic fonts which work with the CJK package. TrueType versions of these fonts for use with XeLaTeX and LuaLaTeX are provided by the arphic-ttf package.

The package allows inline use of Graphviz code, in a LaTeX document.

The ABNT package provides a clean and practical implementation of the ABNT rules for academic texts.

The package provides a class based on memoir to prepare theses and memoirs compliant with the presentation rules set forth by the Faculty of Graduate Studies of Universite Laval, Quebec, Canada. The class also comes with an extensive set of templates for the various types of theses and memoirs offered at Laval.

Please note that the documentation for the class and the comments in the templates are all written in French, the language of the target audience.

Starting with PDF 1.3, PDF files can contain file attachments, i.e., arbitrary files that a reader can extract, just like attachments to an e-mail message. The attachfile package brings this functionality to pdfLaTeX and provides some additional features such as the ability to use arbitrary LaTeX code for the file icon. Settings can be made either globally or on a per-attachment basis. attachfile makes it easy to attach files and customize their appearance in the enclosing document.

OpTeX is a LuaTeX format based on Plain TeX macros with power from OPmac (fonts selection system, colors, external graphics, references, hyperlinks, ...) with Unicode fonts.

This package loads the author's hepunits and hepnicenames packages, and a selection of others that are useful in High Energy Physics papers, etc.
