The package provides interfaces for the user to control PDF parameters, such as line width or text rendering mode. The control operations work in a manner very similar to that of the color package.

The kashida feature in XePersian has problems with some fonts such as the HM Series fonts and the XB Series fonts. This package fixes these problems.

The recipecard class typesets recipes into note card sized boxes that can then be cut out and pasted on to note cards. The recipe then looks elegant and fits in the box of recipes.

The package defines a command \leading, whose argument specifies the nominal distance between consecutive baselines of typeset text. The command replaces the rather more difficult LaTeX command \linespread, where the leading is specified by reference to the font size.

This is an early package for using alternate input encodings. The author considers the package mostly obsolete, since most of its functions are taken by the inputenc package; however, inputenc doesn't support the roman8 and atari encodings, so umlaute remains the sole source of that support.

This package provides the \collect@body command (as in amsmath), as well as a \long version \Collect@Body, for collecting the body text of an environment. These commands are used to define a new author interface to creating new environments.

This package provides an easy to use command. It takes an URL of the Research Organization Registry (ROR) as argument and creates a ROR symbol which links to the given URL---very similar to the orcidlink package from which it is derived. The symbol itself always fits with the chosen font size.

hepunits is a LaTeX package built on the SIunits package which adds a collection of useful HEP units to the existing SIunits set.

The package combines a document's columns into a PDF ``article thread''. PDF readers that support this mechanism can be instructed to scroll automatically from column to column, which facilitates on-screen reading of two-column documents. Even for single-column documents, threadcol supports the creation of multiple article threads, which help organize discontiguous but logically related regions of text into a form that the user can scroll through as if its contents were contiguous.

exceltex is a LaTeX package combined with a helper program written in Perl. It provides an easy to use yet powerful and flexible way to get data from spreadsheets into LaTeX. In contrast to other solutions, exceltex does not seek to make the creation of tables in LaTeX easier, but to get data from spreadsheets into LaTeX as easily as possible. The Excel file format only acts as an interface between the spreadsheet application and exceltex because it is easily accessible (via the Spreadsheet::ParseExcel Perl module) and because most spreadsheet applications are able to read and write Excel files.

This package allows the automatic drawing of the image of objects in spherical mirrors and lenses from the data of the focus, from the position and height of the object. It calculates the position and height of the image, and also displays the notable rays.

This package provides a TeX macro package for easy typesetting programs in Python, C and Pascal. Program source files may also be input.

YaX is advertised as a key system, but it rather organizes attributes in parameters, which parameters can be executed, so that YaX is halfway between key management and macro definition (and actually hopes to provide a user's interface). Values assigned to attributes can be retrieved and tested in various ways, with full expandability ensured as much as possible. Finally, YaX's syntax is a quite peculiar (as few braces as possible), but may be customized.

The package computes and draws 2D Delaunay triangulation. The algorithm is written with Lua, and depending upon the choice of the engine, the drawing is done by MetaPost (with luamplib) or by TikZ. The Delaunay triangulation algorithm is the Bowyer and Watson algorithm. Several macros are provided to draw the global mesh, the set of points, or a particular step of the algorithm.

METAOBJ is a large MetaPost package providing high-level objects. It implements many of PSTricks features for node connections, but also trees, matrices, and many other things. It more or less contains boxes.mp and rboxes.mp. It is easily extensible with new objects.

This package provides font maps and setup tools for Japanese, Korean, Traditional Chinese, and Simplified Chinese. It is the successor of the jfontmaps package. The files in this package contain font maps for dvipdfmx to make various Japanese, Chinese, and Korean fonts available for (u)ptex and related programs and formats.

This is a bundle of macros that the author uses in the coding of others of his macro files.

Econometrics is a package that defines some commands that simplify mathematic notation in economic and econometrics writing. The commands are related to the notation of vectors, matrices, sets, calligraphic and roman letters statistical distributions constants and symbols matrix operators and statistical operators.

These are Adobe Type 1 versions of the OT1-encoded and maths parts of the Computer Modern Bright fonts.

The package is based on pygmentex but provides an automatic run from within the document itself, with the option --shell-escape. It does not need the additional action by the user to run the external program pygmentize to create the code snippets.

The Scientific and Technical Information eXchange (STIX) fonts are intended to satisfy the demanding needs of authors, publishers, printers, and others working in the scientific, medical, and technical fields. They combine a comprehensive Unicode-based collection of mathematical symbols and alphabets with a set of text faces suitable for professional publishing.

This package provides additional rerun warnings if some auxiliary files have changed. It is based on MD5 checksum, provided by pdfTeX.

This package provides LaTeX support for the included Font Awesome 5 icon set.

The original amscd package provides a CD environment that emulates the commutative diagram capabilities of AMS-TeX version 2.x. This means that only simple rectangular diagrams are supported, with no diagonal arrows or more exotic features. This enhancement package implements double, dashed, and bidirectional arrows (left-right and up-down), and color attributes for arrows and their annotations. The restriction to rectangular geometry remains. This nevertheless allows the drawing of a much broader class of commutative diagrams and alike.
