This package provides macros for typesetting virtual keyboards limited to two octaves for showing notes represented by a colored circle. Optionally, the number used for pitch analysis can be shown. It is an extension of piano.sty. It features extended syntax and several options, like setting the color, adding numbers for pitch analysis, one or two octaves, and others.

This package provides special support for the italic ae character in some fonts, due to design flaws (in the author's opinion) regarding this character. At the moment only the fonts TeX Gyre Bonum, TeX Gyre Schola, TeX Gyre Pagella, and the Latin Modern fonts are supported. The other fonts in the TeX Gyre bundle do not need this support.

The luaset package is developed to define finite sets and perform operations on them inside LaTeX documents. There is no particular environment in the package for performing set operations. The package commands can be used in any environment (including the mathematics environment). It is written in Lua, and the .tex file is to be compiled with the LuaLaTeX engine.

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.

STANLI is a STructural ANalysis LIbrary based on PGF/TikZ. Creating new assignments and tests, at university, is usually a very time-consuming task, especially when this includes drawing graphics. In the field of structural engineering, those small structures are a key part for teaching. This package permits creating such 2D and 3D structures in a very fast and simple way.

This package extends the existing LaTeX picture environment, using the familiar technique (the graphics and color packages) of driver files (at present, drivers for dvips, pdfTeX, LuaTeX, XeTeX, VTeX, dvipdfm, and dvipdfmx are available). The package documentation has a fair number of examples of use, showing where things are improved by comparison with the LaTeX picture environment.

Philex provides means for creating and cross-referencing named or numbered environments. Possible uses would be equations, example sentences (as in linguistics or philosophy) or named principles. Cross references may refer either to the number, or to a short name of the target environment, or to the contents of the environment. Philex builds on the facilities of the linguex package.

The package provides a simple interface to OpenStreetMap, and to Google Maps, map images. In the simplest case, it is sufficient to specify the address you need. The package loads the map image using an external Lua script (LaTeX must be running with \write 18 enabled). The Lua script may be used from the command line; a Bash version is provided.

The package offers a solution to the problem that when you link to a float using hyperref, the link anchors to below the float's caption, rather than the beginning of the float. Hypcap defines a separate \capstart command, which you put where you want links to end; you should have a \capstart command for each \caption command.

This package provides a command to print a number with (potentially different) separators every three digits in the parts either side of the decimal point (the point itself is also configurable). The macro is fully expandable and not fragile (unless one of the separators is). There is also a command \sepnumform, that may be used when defining \the<counter> macros.

This package provides a collection of fonts that reproduce those used in old German printing and handwriting. The set comprises Gothic, Schwabacher and Fraktur fonts, a pair of handwriting fonts, Sutterlin and Schwell, and a font containing decorative initials. In addition, there are two re-encoding packages for Haralambous's fonts, providing T1, using virtual fonts, and OT1 and T1, using Metafont.

This MetaPost library was initially written to automate some elements of black and white illustrations for a physics textbook. It provides functions to draw things like lines of variable width, shaded spheres, and tubes of different kinds, which can be used to produce images of a variety of objects. The library also contains functions to draw some objects constructed from these primitives.

This package provides a macro package for typesetting scholarly critical editions. The ledmac package is a LaTeX port of the Plain TeX EDMAC macros. It supports indexing by page and line number and simple tabular- and array-style environments. The package is distributed with the related ledpar and ledarab packages. The package is now superseded by reledmac.

The bundle provides three packages: The mhchem package provides commands for typesetting chemical molecular formulae and equations. The hpstatement package provides commands for the official hazard statements and precautionary statements (H and P statements) that are used to label chemicals. The rsphrase package provides commands for the official Risk and Safety (R and S) Phrases that are used to label chemicals.

This package provides a redefinition of \verb and verbatim so that long lines are breakable before \ and after { with % as hyphen. It allows you to define your own verbatim-like environments (subject to a size limit) and allows you to declare any single character as a shorthand as in the \MakeShortVerb command of the shortvrb package.

This program makes PNG and/or GIF graphics from DVI files as obtained from TeX and its relatives. It offers very fast rendering of DVI as bitmap files, which makes it suitable for generating large amounts of images on-the-fly, as needed in preview-latex, WeBWorK and others. It does not read the postamble, so it can be started before TeX finishes.

This package allows LaTeX constructions (equations, picture environments, etc.) to be precisely superimposed over Encapsulated PostScript figures, using your own favorite drawing tool to create an EPS figure and placing simple text tags where each replacement is to be placed, with PSfrag automatically removing these tags from the figure and replacing them with a user specified LaTeX construction, properly aligned, scaled, and/or rotated.

The package modifies the behaviour of characters in maths mode so that:

• . is used as a one-thousand separator (as is common in Germany);

• , is used as a decimal separator (as is common in Germany);

• -- is represented with spacing as appropriate to such constructs as 1.000,--.

These conversions may be switched on and off.

Dk-bib is a translation of the four standard BibTeX style files (abbrv, alpha, plain and unsrt) and the apalike style file into Danish. The files have been extended with URL, ISBN, ISSN, annote and printing fields which can be enabled through a LaTeX style file. Dk-bib also comes with a couple of Danish sorting order files for BibTeX8.

The package provides the means to typeset factor structures, as are used in many areas of algebraic notation. The structure is similar to the A/B that is provided by the nicefrac package (part of the units distribution), and by the xfrac package; the most obvious difference is that the numerator and denominator's sizes do not change in the \faktor command.

The biocon--biological conventions--package aids the typesetting of some biological conventions. At the moment, it makes a good job of typesetting species names (and ranks below the species level). A distinction is made between the Plant, Fungi, Animalia and Bacteria kingdoms. There are default settings for the way species names are typeset, but they can be customized. Different default styles are used in different situations.

This package will get a description of the current Git version of the document and store it in a command \gitVer. If memoir or fancyhdr are in use, it will also add this to the document footers unless the option noheader is passed. The package also defines a command \versionBox which outputs a box containing the version and date of compilation.

This package allows you to create high-quality publication-ready graphics directly from MGL scripts embedded into your LaTeX document, using the MathGL library.

MathGL is a fast and efficient library by Alexey Balakin for the creation of high-quality publication-ready scientific graphics. Although it defines interfaces for many programming languages, it also implements its own scripting language, called MGL, which can be used independently.

lparse is derived from xparse, but only works with LuaTeX. Just as with xparse, it is possible to use a special syntax consisting of single letters to express the arguments of a macro. However, lparse is able to read arguments regardless of the macro systemd used -- whether LaTeX, or ConTeXt, or even plain TeX. Of course, LuaTeX must always be used as the engine.
