The pgfkeys package (part of the PGF distribution) is a way of defining and using large numbers of keys for key-value syntaxes. However, pgfkeys itself does not offer means of handling LaTeX class and package options. This package adds such option handling to pgfkeys, in the same way that kvoptions adds the same facility to the LaTeX standard keyval package.

This package contains a BibTeX style file, apalike-ejor.bst, made to follow the European Journal of Operational Research reference style guidelines.

There are a number of symbols (e.g., \Square) that are defined by several packages. In order to typeset all the variants in a document, we have to give the glyph a unique name. To do that, we define \savesymbol{XXX}, which renames a symbol from \XXX to \origXXX, and \restoresymbols{yyy}{XXX}, which renames \origXXX back to \XXX and defines a new command, \yyyXXX, which corresponds to the most recently loaded version of \XXX.

This package adds emojis to citations.

This package provides a pgfornament library for Chinese traditional motifs and patterns. The command \pgfornamenthan takes the same options as \pgfornament from the pgfornament package, but renders Chinese traditional motifs instead.

The package provides a simple, configurable, way for neatly typesetting syllogisms and syllogistic-like arguments, composed of two premises and a conclusion.

The package defines a handful of commands for typesetting mathematical symbols of various kinds, ranging from large operators to extensible arrow-like relations and growing arrow-like math accents that all draw from the classic Halloween-related iconography (pumpkins, witches, ghosts, cats, and so on) while being, at the same time, seamlessly integrated within the rest of the mathematics produced by (AmS-)LaTeX.

ProTeX is a simple but powerful literate programming tool, which is designed to generate useful hypertext output (either PDF, or HTML using TeX4ht).

The class provides a variant of the LaTeX standard slides class, in which the user may add headers and footers to the slide.

This package changes the kernel internal \@bsphack/\@esphack so that it is also invisible in vertical mode.

The hologo package provides many useful logos of popular (and not so popular) TeX-family software. However, its interface is a bit cumbersome because you must type \hologoBibTeX instead of \BibTeX. This package makes it possible to import some of the logos provided by hologo as single commands, such as \BibTeX.

Additionally, the package provides logos of some TeX-family software that is popular mainly in Japan. These logos can be imported in the same way as those provided by the \hologo command.

This package provides Czech/Slovak-tuned Computer Modern fonts in the Metafont format; Type 1 format versions (csfonts-t1) are also available.

This package provides the binaries for texlive-psutils.

If you have \cite commands in \section-like commands, or in \caption, the citation will also appear in the table of contents, or list of whatever. If you are also using an unsrt-like bibliography style, these citations will come at the very start of the bibliography, which is confusing. This package suppresses the effect.

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

The package palette contains two files: colorpalette.sty and symbolpalette. One deals with colors and the other deals with symbols; the implementation is quite similar. With this package you can create themes. Each of these themes have a set of colors, and you can create palettes based on this theme with specific color values for each of the theme's color slots. The active palette for each theme can be swapped in to make experimenting with colors easier or give users choices as to which theme they pick.

This package provides support for the Cuprum font family.

The package provides the means to typeset Creative Commons icons, in documents licensed under CC licences. A font (in Adobe Type 1 format) and LaTeX support macros are provided.

The package computes the intersections between arbitrary PostScript paths or Bezier curves, using the Bezier clipping algorithm.

This package provides a Lua module for processing application arguments in the same way as BSD/GNU getopt_long(3) functions do.

tikzpingus is a package similar to tikzducks but with penguins and a vast set of gadgets and extras (capable of changing the wing-positions, body-types, and more).

This package provides the definition of some document-level commands (and some auxiliary functions) that perform the linear regression on a set of data and present the data and the results in tabular and in graphic form.

This small utility, written in SNOBOL, converts the composition of special characters to Unicode.

This package consists of several macros that are shorthand for a variety of physical constants, e.g. the speed of light. The constants can be used in two forms, the most accurate available values, or versions that are rounded to 3 significant digits for use in typical classroom settings, homework assignments, etc. Most constants are taken from CODATA 2018, with the exception of the astronomical objects, whose values are taken from International Astronomical Union specified values. Constants that are derived from true constants, e.g. the fine structure constant, have been calculated using the accepted values of the fundamental constants.
