PerlTeX is a combination Perl script (perltex.pl) and LaTeX2e package (perltex.sty) that, together, give the user the ability to define LaTeX macros in terms of Perl code. Once defined, a Perl macro becomes indistinguishable from any other LaTeX macro. PerlTeX thereby combines LaTeX's typesetting power with Perl's programmability. PerlTeX will make use of persistent named pipes, and thereby run more efficiently. Also provided is a switch to generate a PerlTeX-free, document-specific, noperltex.sty that is useful when distributing a document to places where PerlTeX is not available.

The experimental Unicode-Bidi package allows mixing non-RTL script with RTL script without any markup.

This is a beta version of the STEP Greek font. Only a regular face is available at present, though there are plans to add italic, bold and bold italic in the future. The font only supports LGR in TeX and is meant to serve as a Greek complement to a Times-like font such as STEP. The font supports polytonic Greek.

The package defines variants \mleft and \mright of \left and \right, that make the delimiters act as \mathopen and \mathclose. These commands address spacing difficulties in sub-formulas.

This package extends the cross-reference system of LaTeX2e and introduces concepts of namespace and scope. It also allows users to customize reference formats.

This package provides a set of virtual fonts which emulates T1 coded fonts using the standard CM fonts. The package name, AE fonts, supposedly stands for "Almost European". The main use of the package was to produce PDF files using Adobe Type 1 versions of the CM fonts instead of bitmapped EC fonts. Note that direct substitutes for the bitmapped EC fonts are available, via the CM-super, Latin Modern and (in a restricted way) CM-LGC font sets.

The bundle provides Adobe Type 1 versions of the fonts bbding10, dingbat, karta15, umranda and umrandb.

This package provides a LaTeX package for students of Tsinghua University to write coursework more efficiently. It can also be used by students from other universities.

This package is an as complete as possible manual about bibliographies in LaTeX, and thus mainly about BibTeX.

This package can be used to typeset go diagrams with PSTricks.

This package provides a class which provides the necessary macros to prepare a (classical) concert programme; a sample is provided.

This package provides a Lua module that can parse key-value options like the TeX packages keyval, kvsetkeys, kvoptions, xkeyval, pgfkeys, etc.

This bundle started as an extension to the AGU's own published styles, providing extra facilities and improved usability. The AGU now publishes satisfactory LaTeX materials of its own; it is recommended to switch to the official distribution.

The package allows the user to extract information from the job name, provided that the name has been structured appropriately: the package expects the file name to consist of a set of words separated by hyphens.

This package provides a calligraphic font in the handwriting style. The font is supplied as Metafont source. LaTeX support of the font is provided in the calligra package in the fundus bundle.

The collection contains fonts to represent Aramaic, Cypriot, Etruscan, Greek of the 6th and 4th centuries BCE, Egyptian hieroglyphics, Linear A, Linear B, Nabatean old Persian, the Phaistos disc, Phoenician, proto-Semitic, runic, South Arabian Ugaritic and Viking scripts. The bundle also includes a small font for use in phonetic transcription of the archaic writings.

The design of Didot's 1805 Greek typeface was influenced by the neoclassical ideals of the late 18th century. The font was brought to Greece at the time of the 1821 Greek Revolution, by Didot's son, and was very widely used. The font supports the Greek alphabet, and is accompanied by a matching Latin alphabet based on Zapf's Palatino. LaTeX support is provided, using the OT1, T1, TS1, and LGR encodings.

Circular Glyphs is a graphic alphabet of substitution based on a geometric construction using circles and arcs on a grid. The designs are all based on circular arcs, divided into four quadrants. It is inspired by Star Trek and used by the Bynar and Borg cultures depicted there.

The package provides a diagram environment. This allows the LaTeX user to easily create complex commutative diagrams, by placing formula nodes on a conceptual grid and attaching arrows to them.

This package provides a typical document usually contains many counters: page numbers, section numbers, itemizations, enumerations, theorems, and so on. This module provides a visual display for such counters.

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 facilitates the on-the-fly conversion of various graphics formats to formats supported by pdfLaTeX (e.g., PDF). It uses a range of external programs, and therefore requires that the LaTeX run starts with write18 enabled.

The package integrates the features of xkeyval and of pgfkeys by introducing a new type of handlers. Style keys, links, changing key callbacks and values on the fly, and other features of pgfkeys are introduced in a new context.

This package provides local allocation macros, with names taken from etex.sty but with implementation based on the LaTeX 2015 allocation macros.
