This package provides an introduction to the beamer class, in Portuguese.

The package contains macros for printing various 2/5 bar codes and Code 39 bar codes. The macros do not use fonts but create the bar codes directly using vertical rules. It is therefore possible to vary width to height ratio, ratio of thin and thick bars. The package is therefore convenient for printing ITF bar codes as well as bar codes for identification labels for HP storage media.

This package was a predecessor of longtable; the newer package (designed on quite different principles) is easier to use and more flexible, in many cases, but supertabular retains its usefulness in a few situations where longtable has problems.

The class formats documents in APA style (6th Edition). It provides a full set of facilities in three different output modes (journal-like appearance, double-spaced manuscript, LaTeX-like document). The class can mask author identity for copies for use in masked peer review.

The package can be used to construct dichotomous identification keys (used especially in biology for species identification), taking care of numbering and indentation of successive key steps automatically.

These packages are either mandated by the core LaTeX team, or very widely used and strongly recommended in practice.

This package allows the user to input formatted data into elements of a 2-D or 3-D array and to recall that data at will by individual cell number. The data can be but need not be numerical in nature. It can be, for example, formatted text.

This package typesets physical units following the rules of the International System of Units (SI). Note that the package is now superseded by siunitx; siunits has maintenance-only support, now.

This package provides environments for hanging paragraphs and list items. In addition, it defines environments for labeled paragraphs and list items.

This package provides a BibLaTeX style to format reference lists in the Harvard style recommended by the University of Bath Library.

The mdframed package develops the facilities of framed in providing breakable framed and coloured boxes. The user may instruct the package to perform its operations using default LaTeX commands, PStricks or TikZ.

This package provides solutions to a number of common difficulties in writing displayed equations and getting high-quality output. The single most ambitious goal of the package is to support automatic linebreaking of displayed equations. The bundle also contains the flexisym and mathstyle packages, which are both designated as support for breqn.

This package provides macros and an environment to generate timing diagrams (digital waveforms) without much effort. The TikZ package is used to produce the graphics. A tabular-like environment is provided to produce larger timing diagrams.

The font contains a single character: the Begriffsschrift quantifier (in several sizes), as used to set the Begriffsschrift (concept notation) of Frege. The font is not intended for end users; instead it is expected that it will be used by other packages which implement the Begriffsschrift.

This package provides direct support for Unicode emoji in pdfLaTeX, with full access to emoji sequences including but not limited to flag sequences, diversity modifier sequences, and tag sequences.

This is a LaTeX package for using colors from the current Beamer theme in PGFPlots diagrams.

This package provides the binaries for texlive-t1utils.

This package provides a document class and bibliographic style that prepares documents in the style required by the ASCE. These are unofficial files, not sanctioned by that organization.

The Pigpen cipher package provides the font and the necessary wrappers (style file, etc.) in order to write Pigpen ciphers, a simple substitution cipher. The package provides a font (available both as Metafont source, and as an Adobe Type 1 file), and macros for its use.

The package simplifies the preparation of Swiss documents and letters by setting up linguistic and common packages. While it is a useful addition to the chletter document class, it is not tied to it and may be used as a general purpose package.

This LaTeX package provides both syntactic and semantic helpers to typeset mathematics in LaTeX. The syntactic layer eases typesetting of formulae in general, while the semantic layer provides commands like \inner{x}{y} to unify typesetting of inner products. These not only unify typesetting of math formulae but also allow easily adapting notation if a user prefers to. The semantic layer is split into topics.

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

LaTeX, by default, restricts the sizes at which you can use its default computer modern fonts, to a fixed set of discrete sizes (effectively, a set specified by Knuth). The type1cm package removes this restriction; this is particularly useful when using scalable versions of the cm fonts (Bakoma, or the versions from BSR/Y&Y, or True Type versions from Kinch, PCTeX, etc.). Note that the LaTeX distribution now contains a package fix-cm, which performs the task of type1cm, as well as doing the same job for T1- and TS1-encoded ec fonts.

This package offers a variety of features for documenting LaTeX packages, ensuring consistent presentation, cross-referencing, and index generation. It also supports version and change tracking to maintain a consistent change history.
