This package provides various different formats for the text created by the command \today, and also provides commands for displaying the current time (or any given time), in 12-hour, 24-hour or text format. It overrides Babel's date format, having its own library of date formats in different languages. This package is now obsolete and has been replaced by datetime2.

Catchfile catches the contents of a file and puts it in a macro.

The hep-math package provides some additional features beyond the mathtools and amsmath packages.

The package provides commands for creating a grid of rectangles, and commands for populating locations in the grid. PGF/TikZ is used for placement and population of the cells.

The package extends the facilities of the pict2e and the curve2e packages, providing extra reference frames, conic section curves, graphs of elementary functions and other parametric curves.

This package lets you typeset keywords of the version control system Subversion inside your LaTeX files anywhere you like. Unlike the otherwise similar package svn, the use of multiple files for one LaTeX document is well supported. The package interacts with an external Perl script, to retrieve information necessary for the required output.

This package provides a Python script to support changing or creating DVI files via disassembling into text, editing, and then reassembling into binary format. It supports advanced features such as adding a preprint number or watermarks.

The bundle shows the construction of PSTricks macros to draw Riemann sums of an integral and to draw the vector field of an ordinary differential equation. The results are illustrated in a fragment of lecture notes.

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.

This package provides TrueType versions of the Chinese Arphic fonts for use with XeLaTeX and LuaLaTeX. Type1 versions of these fonts, for use with pdfLaTeX and the cjk package, are provided by the arphic package.

This package adds two user commands to standard PiCTeX. One command uses relative coordinates, thus eliminating the need to calculate the coordinate of every point manually as in standard PiCTeX. The other command modifies \plot to use a rule instead of dots if the line segment is horizontal or vertical.

The package provides commands to formalize textual variants in critical editions typeset using eledmac.

The package provides the language definition file for support of Vietnamese in Babel.

This is the Vietnamese version of the Short Introduction to LaTeX2e.

This collection includes music-related fonts and packages.

Typeset footnotes in run-on paragraphs, instead of one above another; this is a re-seating, for the LaTeX environment, of an example in the TeXbook. The same basic code, improved for use in e-TeX-based LaTeX, appears in the comprehensive footnote package footmisc, and superior versions are also available in the manyfoot and bigfoot packages.

The package allows the user to filter out unwanted warnings and error messages issued by LaTeX, packages and classes, so they won't pop out when there's nothing one can do about them. Filtering goes from the very broad (``avoid all messages by such and such'') to the fine-grained (``avoid messages that begin with...''). Messages may be saved to an external file for later reference.

This package typesets Miller indices that are used in material science with an easy syntax. Minus signs are printed as bar above the corresponding number.

This package is unneeded and does nothing when used with a LaTeX format 2020-10-01 or newer as in this case the format provides the \AtEndDvi command. For older formats it implements \AtEndDvi, a counterpart to \AtBeginDvi. The execution of its argument is delayed to the end of the document at the end of the last page. Thus \special and \write remain effective, because they are put into the last page. This is the main difference to \AtEndDocument.

The package computes the number of sheets of paper used by, and hence the mass of a document. This is useful (for example) when calculating postal charges.

Xindy was developed after an impasse had been encountered in the attempt to complete internationalisation of makeindex. Xindy can be used to process indexes for documents marked up using (La)TeX, Nroff family and SGML-based languages. Xindy is highly configurable, both in markup terms and in terms of the collating order of the text being processed.

This package provides a TikZ-based solution to typeset visualisations of tone values. Currently, unt's model is implemented. Support for more models is planned.

In 1994, with LaTeX2e, the old font commands \rm, \sf, \tt, \bf, \it, \sl, and \sc became obsolete. This package defines them, and also the deprecated KOMA-Script command \sfb.

Pages of a document processed with the booklet package will be reordered and scaled so that they can be printed as four pages per physical sheet of paper, two pages per side. The resulting sheets will, when folded in half, assemble into a booklet.
