These files record details of problems reported in Knuth's Computers and Typesetting series of books, for the Computer Modern fonts, and for TeX, Metafont and related programs.

The package can generate thumb indexes for your document. It features printing thumb indexes on one- or two-sided pages, along with background- and foreground-color selection and full LaTeX styling of the chapter numbers in the thumb indexes. The height of each thumb index is automatically chosen based on the number of chapters in your document, while the width is chosen by the user. The package is designed to work with the memoir class, and also requires PerlTeX and TikZ.

The randomwalk package provides a user command, \RandomWalk, to draw random walks with a given number of steps. Lengths and angles of the steps can be customized in various ways.

The pagelayout class enables you to layout pages declaratively using simple macros for pages, covers, grids, templates, text, and graphics to create graphic rich, perfectly typeset, and print ready PDFs. The integration of Inkscape allows your to create box shadows. The integration of ImageMagick allows you to configure compression and sharpening for bitmap graphics to export web, print or preview versions of your document. Parallelized image optimization, caching, and a draft mode enable fast PDF creation and a responsive workflow, even for large documents with lots of photos and graphics.

The package provides a macro for reflecting images, in a number of different ways, in pursuit of more striking graphics in a document.

This package lets you draw Feynman diagrams using TikZ. It is a low-end modification of the TikZ-Feynman package, one of whose principal advantages is the automatic generation of diagrams, for which it needs LuaTeX. TikZ-FeynHand only provides the manual mode and hence runs in LaTeX without any reference to LuaTeX. In addition it provides some new styles for vertices and propagators, alternative shorter keywords in addition to TikZ-Feynman's longer ones, some shortcut commands for quickly customizing the diagrams look, and the new feature of putting one propagator on top of another.

This LaTeX package helps you write source code in your academic papers and make it looks neat. It uses minted and tcolorbox, configuring them the right way, to ensure that code fragments and code blocks look nicer.

The package can fetch the date declaration of packages and files used by a document, and then provide the information in macros. The facilities provide a means of obtaining the date of a package being documented.

This is a collection of packages for LuaTeX, a TeX engine using Lua as an embedded scripting and extension language, with native support for Unicode, OpenType/TrueType fonts, and both PDF and DVI output. The LuaTeX engine itself, and plain formats, are in collection-basic.

The longfigure package uses and relabels components of the well-known longtable package to provide a table-like environment that can display a stream of figures as a single figure that can break across pages.

This package enables the presentation of individual profiles, which may be useful for genealogical or local history treatises. Each profile is typeset using key/value-configurable environments, and a number of macros are provided to enable references and name formatting.

If your LaTeX document is version-controlled with Git, you might encounter situations, where you want to include some information of your Git repository into your LaTeX document, e.g., to keep track on who gave you feedback on which version of your document. This Git information can be included on every page by a watermark or (for custom needs) via provided variables.

The package provides OCG (Optional Content Groups) support within a PDF document, replacing the file.sty distributed with Asymptote. Nested OCGs are supported. The package may be used with pdfLaTeX and XeLaTeX.

The package provides syntax highlighting for the Q# language, a domain-specific language for quantum programming.

The package spits out sentences in Kantian style; the text is provided by the Kant generator for Python by Mark Pilgrim, described in the book ``Dive into Python''. The package is modelled on lipsum, and may be used for similar purposes.

This package provides a style file for use with the letter class that overwrites the \opening and \closing macros so that letters can be styled with the block letter style instead of the default style. Thus, the return address, the closing, and the signature appear flushed on the left margin.

This is a LaTeX class created for Brazilian students to facilitate the use of standards from the ABNT in academic works like TCCs, dissertations, theses.

The package provides a command \forloop for doing iteration in LaTeX macro programming.

The class produces a document that conforms to the format described in the University's Handbook for Graduate Students Preparing to Deposit.

ctan_chk is a basic Gawk program that uses CTAN's published guidelines for authors to help eliminate sloppiness in uploaded files/projects. It is completely open for users to program additional guidelines as well as CTAN's future adjustments.

epsf-dvipdfmx.tex is a plain TeX file to be \input after epsf.tex when using plain TeX with dvipdfmx. It is needed when an .eps file has anything except the origin for the lower-left of its bounding box.

This package provides a derivative of the CV class available to LyX users (renamed to avoid the existing cv package).

This package provides Adobe Photoshop Data format (PSD) support for the graphicx package with the convert command from ImageMagick.

This is Fontname, a naming scheme for (the base part of) external TeX font filenames. This makes at most eight-character names from (almost) arbitrarily complex font names, thus helping portability of TeX documents.
