The package allows the user to generate multiple documents from a single source, by marking pieces of the document with tags and specifying which marked pieces to include or exclude.

The hanging package facilitates the typesetting of hanging paragraphs. The package also enables typesetting with hanging punctuation, by making punctuation characters active.

This PSTricks package provides a really rather simple command \PstPolygon that will draw various regular and non-regular polygons (according to command parameters); various shortcuts to commonly-used polygons are provided, as well as a command \pspolygonbox that frames text with a polygon.

This package provides a wrapper for the truncate package, thus fixing issues related to LuaTeX's hyphenation algorithm.

This package provides macros for measuring alphabet lengths (i.e., the length occupied by the characters abcd...xyz), em-widths and ex-heights, which may help in making typesetting decisions.

The package allows the user to override existing labels (for example, those generated automatically).

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.

This LaTeX package provides a command to convert dates to names of Japanese holidays. Another command, converting dates to the day of the week in Japanese, is available as a free gift.

Typesetting bagpipe music in MusixTeX is needlessly tedious. This package provides specialized and re-defined macros to simplify this task.

The package amends the \see and \seealso macros that are used in building indexes with MakeIndex, to deal with repetitions, and to ensure page numbers are present in the actual index entries.

This is an advanced letter document class which extends LaTeX's usual letter class, providing support for building your own letterhead and marking fold points for window envelopes. The class supersedes an earlier class called myletter.

The package defines the \efbox command, which creates a box just wide enough to hold the text created by its argument. The command optionally puts a (possibly partial) frame around the box, and allows setting the box background colour.

This class file complies with the Digital Submission Requirement for masters and PhD thesis submissions of the University of Texas at Austin.

The package establishes Catalan conventions in a document (or a subset of the conventions, if Catalan is not the main language of the document).

The package provides macros holding file name information (directory, base name, extension, full name and full path) for files read by LaTeX \input and \include macros; it uses the file hooks provided by the author's filehook. In particular, it restores the parent file name after the trailing \clearpage of an \included file; as a result, the macros may be usefully employed in the page header and footer of the last printed page of such a file. The depth of inclusion is made available, together with the parent (including file) and parents (all including files to the root of the tree). The package supersedes FiNK.

Erewhon is based on the Heuristica package, which is based in turn on Utopia. Erewhon adds a number of new features --- small caps in all styles rather than just regular, added figure styles (proportional, inferior, numerator, denominator) and superior letters. The size is 6% smaller than Heuristica, matching that of UtopiaStd.

This package allows you to draw elements of the diagram monoids, commonly referred to as diagrams.

This bundle provides fonts to go with the cjk macro package for Chinese, Japanese and Korean with LaTeX2e. The package aims to supersede HLaTeX fonts bundle.

This package is a LaTeX adaptation of a set of tools developed for ConTeXt reproduction of Oliver Byrne's 1847 edition of the first six books of Euclid's Elements; see https://github.com/jemmybutton/byrne-euclid. It consists of a MetaPost library, responsible for all the drawing and a set of LaTeX macros to conveniently use them.

Algorithm2e is an environment for writing algorithms. An algorithm becomes a floating object (like figure, table, etc.). The package provides macros that allow you to create different keywords, and a set of predefined key words is provided; you can change the typography of the keywords. The package allows vertical lines delimiting a block of instructions in an algorithm, and defines different sorts of algorithms such as Procedure or Function; the name of these functions may be reused in the text or in other algorithms.

The tclldoc package and class simplify the application of the doc/docstrip style of literate programming with Tcl. The tclldoc package is a bit like the doc package is for LaTeX, whereas the tclldoc class more parallels the ltxdoc class.

The package offers support for drawing tree diagrams, and is especially suitable for linguistics use. It allows trees to be specified in a simple bracket notation, automatically calculates branch sizes, and supports both DVI/PostScript and PDF output by use of pict2e facilities. The package is a development of the existing qobitree package, offering a new front end.

This package provides font information needed to load the cmmi and cmmib fonts for use to produce old-style numbers.

This package provides a file written with TeX, not using any packages, to be compiled with TeX or pdfTeX only, not with LaTeX and al.
