This package provides a command for the LaTeX programmer for testing whether an argument is empty.

The package contains the OpenType medieval cursive font Aboensis and a style file to use it in XeLaTeX documents. The font is based on Codex Aboensis, that is a law book written in Sweden in the 1430s. Since medieval cursive is very difficult to read for modern people, the font is not suitable for use as an ordinary book font, but is intended for emulating late medieval manuscripts.

The font contains two sets of initials: lombardic and cursive to go with the basic alphabet, and there is support for writing two-colored initials and capitals. There are also a large number of abbreviation sigla that can be accessed as ligature substitutions. The style file contains macros that help to use the extended features of the font such as initials and two-colored capitals. There are also macros to help achieve even pages with consistent line spacing.

The package provides commands for splitting a token list at the first occurrence of another (specified) token list. The package's mechanism differs from those of packages providing similar features, in the following ways: the method uses TeX's mechanism of reading delimited macro parameters; splitting macros work by pure expansion, without assignments; the operation is carried out in a single macro call. A variant of the operation is provided, that retains outer braces.

This package provides a set of MetaPost macros for typesetting derivation trees (such as used in sequent calculus, type inference, programming language semantics...).

Xindy was developed after an impasse had been encountered in the attempt to complete internationalisation of makeindex. Xindy can be used to process indexes for documents marked up using (La)TeX, Nroff family and SGML-based languages. Xindy is highly configurable, both in markup terms and in terms of the collating order of the text being processed.

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

The package is written in order to help identifying the rightful addressee for a bug report. The LaTeX team asks that it will be loaded in any test file that is intended to be sent to the LaTeX bug database as part of a bug report.

This bundle presents the whole of Beccari's original Greek font set, which use the Lispiakos font shape derived from the shape of the fonts used in printers' shops in Lispia. The fonts are available both as Metafont source and in Adobe Type 1 format, and at the same wide set of design sizes as are such font sets as the EC fonts.

Cantarell is a contemporary Humanist sans serif designed by Dave Crossland and Jakub Steiner. The present package provides support for this font in LaTeX. It includes Type 1 versions of the fonts, converted for this package using FontForge from its sources, for full support with Dvips.

This MetaPost package allows to draw binary Huffman trees from two arrays: an array of strings, and an array of weights (numeric). It is based on the METAOBJ package which provides many tools for building trees in general.

This package provides a simple package providing nuclear sub- and superscripts as commonly used in radiochemistry, radiation science, and nuclear physics and engineering applications. Isotopes which have Z with more digits than A require special spacing to appear properly; this spacing is supported in the package.

The ncc class provides a framework for a common class to replace the standard article, book and report classes, and providing a preprint class. The class's extensions are provided in a number of small packages, some of which may also be used with the standard classes.

The package provides a means of marking a source, so that samples of it may be included in a document (by means of the listings package) in a stable fashion, regardless of any change to the source. The markup in the source text defines tags for blocks of source. These tags are processed by a shell script to make a steering file that is used by the package when LaTeX is being run.

The bibleref package offers consistent formatting of references to parts of the Christian Bible, in a number of well-defined formats.

The package allows a lot of flexibility in constructing question and answer sheets.

This package is an extension to the exam document class. It provides the user with four new multiple choice typesetting environments which place their content in a random order. It can (only) be used in combination with the exam class. The questions themselves cannot be randomized with this package. Furthermore, the package provides a simple answer key table typesetter and has a command for writing the answer keys to an external file.

This package provides support for use of Libertinus fonts with traditional processing engines (LaTeX with Dvips or Dvipdfmx, or pdfLaTeX).

pdf-trans is a set of macros offering various transformations of TeX boxes (based on plain and pdfeTeX primitives).

This package provides two shorthands for typesetting breaking and non-breaking small spaces, where both hyphenation and kerning against space are correctly applied. Additionally, interword kerning can be applied.

The package offers support for the Calligra handwriting font, in LaTeX documents. The package is part of the fundus bundle.

This package aims to provide a single style file containing most configurations and macros necessary to write appealing publications in High Energy Physics. Instead of reinventing the wheel by introducing newly created macros, hep-paper preferably loads third party packages as long as they are light-weight enough. For usual publications it suffices to load the hep-paper package, without optional arguments, in addition to the article class.

This is an approximate equivalent of the Xerox Pica typeface; the font is optimised for submitting fiction manuscripts to mainline publishers. The font is a fixed-width one, rather less heavy than Computer Modern typewriter. Emphasis for bold-face comes from a wavy underline of each letter. The two fonts are supplied as Metafont source.

This package offers low-level mplib integration for plain LuaTeX and is designed with the purpose of being easy to extend. The use of multiple simultaneous MetaPost instances is supported, as well as running TeX or lua code from within MetaPost. With the included minim-mp format file, you can even use LuaTeX as a stand-alone MetaPost compiler.

The package uses PSTricks to draw the Julia and Mandelbrot sets, the Sierpinski triangle, Koch flake, and Apollonius Circle as well as fractal trees (which need not be balanced) with a variety of different parameters (including varying numbers of iterations).
