The mhequ style file simplifies creating multi-column equation environments and tagging equations therein. It supports sub-numbering of blocks of equations, such as (1.2a) and (1.2b), references to each equation individually (1.2a) or to the whole block (1.2). The labels can be shown in draft mode. The default behaviour is to show an equation number if and only if the equation actually has a label, which reduces visual clutter.

This package provides a set of bibliography tools. It includes:

• aux2bib, a Perl script which will take an .aux file and make a portable .bib file to go with it;

• bibify, a shell script that will optimize away one pass of the LaTeX-BibTeX cycle, in some cases;

• bibkey, a shell script that finds entries whose keyword field matches the given keys (uses sed and awk);

• cleantex, a shell script to tidy up after a LaTeX run;

• looktex, a shell script to list entries that match a given regexp;

• makebib, a shell script to make an exportable .bib file from an existing (set of) .bib file(s) and an optional set of citations (uses sed);

• printbib, a shell script to make a DVI file from a .bib file, sorted by cite key, and including fields like keyword, abstract, and comment;

• bib2html, a Perl script that makes a browsable HTML version of a bibliography (several .bst files are supplied);

• and citekeys, a shell script that lists the citation keys of a .bib file.

This package provides a collection of Thai fonts, supplied as FontForge sources, and with LaTeX .fd files.

The package makes available the pdfjam shell script that provides a simple interface to much of the functionality of the excellent pdfpages package for LaTeX. The pdfjam script takes one or more PDF files (and/or JPG/PNG graphics files) as input, and produces one or more PDF files as output. It is useful for joining files together, selecting pages, reducing several source pages onto one output page, etc.

The package adds blurred/faded/fuzzy shadows to PGF/TikZ pictures. It is configured as a TikZ/PGF library module.

Tinos, designed by Steve Matteson, is an innovative serif design that is metrically compatible with Times New Roman.

This is a collection of 45 fonts, created by QualiType.

This package contains a collection of symbols for typesetting electrical wiring diagrams for relay control systems. The symbols are meant to be in agreement with the international standard IEC-60617 which has been adopted worldwide, with perhaps the exception of the USA. It extends and modifies, when needed, the TikZ-library circuits.ee.IEC. A few non-standard symbols are also included mainly to be used in presentations, particularly with the beamer package.

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.

The package aims to streamline the work of typesetting, and to provide the look and feel of harvmac for readers.

The package draws Bao diagrams in LaTeX. The package is a development of psgo, and uses PSTricks to draw the diagrams.

This package adds the \keyboard[1][2]..[7] command to your project. When used, it draws a small 2 octaves piano keyboard on your document, with up to 7 keys highlighted.

This package provides a Python script and a LaTeX .sty file which can be used together to include Jupyter Notebooks (all of them, or some specific cells) as part of a LaTeX document. It will convert the Jupyter Notebook format to proper LaTeX so it gets included seamlessly, supporting text, LaTeX, images, etc.

The package supports XeTeX's (and other putative future similar engines') need for Unicode characters, in a similar way to what the fontenc does for 8-bit (and the like) fonts: convert accent-glyph sequence to a single Unicode character for output. The package also covers glyphs specified by packages (such as tipa) which define many commands for single text glyphs.

The package allows selection of Latin Modern Typewriter fonts with scaling and access to all its features.

This package provides the translation into German of the documentation of microtype.

In Die TeXnische Komodie (issue 1/2013) Christian Justen described his use of LaTeX in his work as priest (similar requirements may be encountered in the work of pastors and other ministers of religion). One point was to arrange A5 pages onto A4 landscape paper, either side-by-side or as a booklet. Justen made two Bash scripts for this job; the package provides one Texlua script for both requirements.

This collection provides support for Arabic and Persian.

The package takes control of the six TeX token registers \everypar, \everymath, \everydisplay, \everyhbox, \everyvbox and \everycr. Real hooks for each of the registers may be installed using a stack like interface. For backwards compatibility, each of the \everyX token lists can be set without interfering with the hooks.

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 package provides a range of differential, partial differential and delimiter commands, together with a \fullfunction (function, with both domain and range, and function operation) and various reference commands.

This package provides math support via newtxmath for NotoSerif and NotoSans. (Regular and Bold weights only.)

This package provides for a variety of continuation indicators on pages when the text continues on the following page. The default is to only mark odd pages, but all pages can be marked and the marking can be stopped or started at any point.

This package typesets the turnstile sign. Among other uses, this sign is used by logicians for denoting a consequence relation, related to a given logic, between a collection of formulas and a derived formula.
