This package carefully selects and defines 9 colors for 13 hues each. All colors with the same suffix number have equal luminance level. Also the color black is of level 0, and the color white is of level 10. By simply choosing two colors in the above list, which differ in level by at least 5, as foreground and background colors, you will get proper WCAG Color Contrast.

This package provides two commands (\chordscheme and \scales). With those commands it is possible to draw schematic diagrams of guitar chord tablatures and scale tablatures. Both commands know a range of options that allow wide customization of the output.

The package establishes Basque conventions in a document.

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.

Currvita is a package rather than a class (like most other curriculum vitae offerings). The author considers that a curriculum vitae can quite reasonably form part of another document (such as a letter, or a dissertation).

The package offers improvement of the Latvian language support in polyglossia, in particular in the area of the standard classes.

PostScript lacks a lot of basic operators such as tan, acos, asin, cosh, sinh, tanh, acosh, asinh, atanh, exp (with e base). Also (oddly) cos and sin use arguments in degrees. Pst-math provides all those operators in a header file pst-math.pro with wrappers pst-math.sty and pst-math.tex. In addition, sinc, gauss, gammaln and bessel are implemented (only partially for the latter). The package is designed essentially to work with pst-plot but can be used in whatever PS code. The package also provides a routine SIMPSON for numerical integration and a solver of linear equation systems.

If PDF files are included using pdfTeX, PDF annotations are stripped. The Pax project offers a solution without altering pdfTeX. A Java program (pax.jar) parses the PDF file that will later be included. The program then writes the data of the annotations into a file that can be read by TeX. The LaTeX package pax extends the graphics package to support the scheme: if a PDF file is included, the package looks for the file with the annotation data, reads them and puts the annotations in the right place.

LaTeX's figures, tables, and \marginpars are dangerous for footnotes (and probably also \enlargethispage). Here is a proposal (a patch package) to help, by using \holdinginserts in a simple way. It replaces the original problem with a new one --- it is an experiment to find out whether the new problem is less bad (or it is just a contribution to the discussion, maybe just a summary of previous work).

This package keeps track of files included in your document, with \input or \include. You then have permanent access to the name of the file currently being processed through the macro \finkfile.

FiNK has been deprecated and is not maintained anymore. People interested in FiNK's functionality are invited to use a package named currfile instead.

The package provides a macro \Inline that precedes a \def or \gdef. Within the definition text of an inlined definition, keywords such as \Expand may be used to selectively inline certain expansions at definition-time. This eases the process of redefining macros in terms of the original definition, as well as definitions in which the token that must be expanded is deep within, where \expandafter would be difficult and \edef is not suitable. Another application is as an easier version of \aftergroup, by defining a macro in terms of expanded local variables, then ending the group with \expandafter\endgroup\macro.

This package provides utilities and documentation related to TeX dimensional units, usable both with Plain TeX and with LaTeX.

The purpose of this package is to decrease the number of keystrokes needed to typeset small amounts of aligned material (matrices, arrays, etc.). It provides a facility for typing alignment environments and macros with spaces as the alignment delimiter and semicolons (by default) as the end-of-row indicator. This package also contains utility macros for typesetting augmented matrices, vectors, arrays, systems of equations, and more, and is easily extendable to other situations that use alignments. People who have to typeset a large number of matrices (like linear algebra teachers) should find this package to be a real time saver.

limecv is a LaTeX document class to write curriculum vitae. It is designed with the following design rules: simple, elegant and clean. To this end, it offers several environments and macros for convenience.

LaTeX2e's filecontents and filecontents* environments enable a LaTeX source file to generate external files as it runs through LaTeX. However, there are two limitations of these environments: they refuse to overwrite existing files, and they can only be used in the preamble of a document. The filecontents package removes these limitations, letting you overwrite existing files and letting you use filecontents filecontents* anywhere.

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 package provides four commands for vertically scaling and stretching objects. Its primary function is the ability to scale/stretch and shift one object to conform to the size of a specified second object. This feature can be useful in both equations and schematic diagrams. Additionally, the scaling and stretching commands offer constraints on maximum width and/or minimum aspect ratio, which are often used to preserve legibility or for the sake of general appearance.

The package offers XeTeX and LuaTeX support for the sans serif OpenType Fira Math font.

The package contains a number of PostScript fonts derived from the STIX OpenType fonts that may be used in maths mode in regular and bold weights for Calligraphic, Fraktur and Double-struck alphabets. Virtual fonts with metrics suitable for maths mode are provided, as are LaTeX support files.

upTeX is an extension of pTeX, using UTF-8 input and producing UTF-8 output. It was originally designed to improve support for Japanese, but is also useful for documents in Chinese and Korean. It can process Chinese simplified, Chinese traditional, Japanese, and Korean simultaneously, and can also process original LaTeX with \inputenc{utf8} and Babel (Latin/Cyrillic/Greek etc.) by switching its \kcatcode tables.

This package fixes problems with colour loss that occurres in the environments of the framed package.

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

This package provides variants of \fbox: \shadowbox, \doublebox, \ovalbox, \Ovalbox, with helpful tools for using box macros and flexible verbatim macros. You can box mathematics, floats, center, flushleft, and flushright, lists, and pages.

This package provides a drop-in replacement for the Avant Garde font from Adobe's basic set.
