The package enables the user to connect information, and to place labels, without knowing (in advance) the actual positions of the items to be connected, or where the connecting line should go. The macros are useful for making graphs and trees, mathematical diagrams, linguistic syntax diagrams, and so on.

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 tries to prevent overflow lines in paragraphs or boxes. It changes LuaTeX's \linebreak callback and re-typesets the paragraph with increased values of \tolerance and \emergencystretch until the overflow no longer happens. If that doesn't help, it chooses the solution with the lowest badness.

This package provides tools to draw most of the geometrical constructions that a high school instructor or bachelor degree professor might need to teach geometry. The connection to Euclide depends on the fact that in his times calculations were made with ruler, compass and also with ellipsograph. This package extends the functionalities of the curve2e package.

The package uses PSTricks to draw bar charts from data stored in a comma-delimited file. Several types of bar charts may be drawn, and the drawing parameters are highly customizable.

The pgfgantt package provides an environment for drawing Gantt charts that contain various elements (titles, bars, milestones, groups and links). Several keys customize the appearance of the chart elements.

Pages of a document processed with the booklet package will be reordered and scaled so that they can be printed as four pages per physical sheet of paper, two pages per side. The resulting sheets will, when folded in half, assemble into a booklet.

Packages provides creation of sequential numeric labels for entities in a document. The motivating example is chemical structures in a scientific document. The package can automatically output a full object name and label on the first occurrence in the document and just labels only on subsequent references.

This package provides some LaTeX support for the use of EBGaramond12 in mathematics.

This LaTeX package provides macros based on TikZ to draw a game tree. The main idea underlying its core macros is the completion of a whole tree by using a sequence of simple parent-child tree structures, with no longer nested relations involved (like the use of grandchildren or great-grandchildren). Using this package you can draw a game tree as easily as drawing a game tree with pen and paper.

The package defines some commands and styles to support drawing straight-edge and compass diagrams with TikZ.

This package provides commands to typeset proof trees in the style of sequent calculus and related systems.

The package makes a quick hack to ziffer to display numbers in maths mode according to ISO 31-0, regardless of input format (European $1.235,7$ or Anglo-American $1,235.7$).

The rotpages package allows you to format documents where small sets of pages are rotated by 180 degrees and rearranged, so that they can be read by turning the printed copy upside-down. It was developed for collecting exercises and solutions: using the package, you can print the exercise text normally and the solutions rotated.

The package provides a macro \sidenote, that places a note in the margin of the document, with its baseline aligned with the baseline in the body of the document. These sidenotes are numbered (both in the text, and on the notes themselves).

DSSerif is a mathematical font package with double struck serifed digits, upper and lower case letters, in regular and bold weights. The design was inspired by the STIX double struck fonts, which are sans serif, but starting from a Courier-like base.

TeX by Topic is a book originally published by Addison-Wesley. It describes itself as ``a TeXnician's reference'', and covers the way TeX (the engine) works in as much detail as most ordinary TeX programmers will ever need to know.

This (deprecated) package provides support for the manipulation and reference of small, or sub, figures and tables within a single figure or table environment. It is convenient to use this package when your subfigures are to be separately captioned, referenced, or are to be included in the List-of-Figures. A new \subfigure command is introduced which can be used inside a figure environment for each subfigure. An optional first argument is used as the caption for that subfigure. The package is now considered obsolete: it was superseded by subfig, but users may find the more recent subcaption package more satisfactory.

This package provides provides colors with French names, based on xcolor and xkcdcolors.

This package adds Norwegian Bokmal translations for the glossaries package. These will be loaded automatically when the Babel package is loaded with the option norsk.

The sudoku package provides an environment for typesetting sudoku grids.

The main goal of this package is to offer additional database fields and formats for the genealogytree package, particularly for typesetting large trees.

The varwidth environment is superficially similar to minipage, but the specified width is just a maximum value -- the box may get a narrower natural width.

The package provides macros for typesetting math formulas in mixed horizontal and vertical mode, automatically as best fit. It provides an environment mathpar that behaves much as a loose centered paragraph where words are math formulas, and spaces between them are larger and adjustable. It also provides a macro \inferrule for typesetting fractions where both the numerator and denominator may be sequences of formulas that will be also typeset in a similar way. It can typically be used for typeseting sets of type inference rules or typing derivations.
