This package provides a development of TeX, which deals in multi-octet Unicode characters, to enable native treatment of a wide range of languages without changing character-set. Work on Omega has ceased; its compatible successor is Aleph, which is itself also in major maintenance mode only. Ongoing projects developing Omega (and Aleph) ideas include Omega-2 and LuaTeX.

David K. Lewis (Counterfactuals, Blackwell 1973) introduced a sphere semantics for counterfactual conditionals. He jokingly referred to the diagrams depicting such sphere models as Ptolemaic astronomy, hence the name of this package. The macros provided in this package aid in the construction of sphere model diagrams in the style of Lewis.

This package approaches the problem of the shortage of registers, by providing a mechanism for local allocation. The package works with Plain TeX and LaTeX.

sfmath is a simple package for sans serif maths in documents. After including the package, all maths of the current document is displayed with sans serif fonts.

Cochineal is a fork from the Crimson fonts (Roman, Italic, Bold, BoldItalic only), which contain roughly 4200 glyphs in the four styles mentioned above. Cochineal adds more than 1500 glyphs in those styles so that it is possible to make a TeX support collection that contains essentially all glyphs in all styles. The fonts are provided in OpenType and PostScript formats.

Epigrafica is a Greek and Latin font, forked from the development of the Cosmetica font, which is a similar design to Optima and includes Greek.

This package implements the standard layout for German term papers in law (one-and-half linespacing, 7 cm margins, etc.). It includes alphanum that permits alphanumeric section numbering (e.g., A. Introduction; III. International Law).

The bundle offers versions of the standard LaTeX article and report classes, rewritten to reflect a more European design, and the a4 package, which is better tuned to the shape of a4 paper than is the a4paper class option of the standard classes. The classes include several for article and report requirements, and a letter class. The elements of the bundle were designed by members of the Dutch TeX Users Group NTG.

This package adds support for traces in trees created using either the synttree or the qtree package. The package provides two commands (\traceLabel and \traceReference) to set and use a trace.

TeX's \let assignment does not work for LaTeX macros with optional arguments or for macros that are defined as robust macros by \DeclareRobustCommand. This package defines \LetLtxMacro that also takes care of the involved internal macros.

This LaTeX package produces mailing envelopes and labels, including barcodes and address formatting according to the US Postal Service rules.

This package provides Italian date and time styles that use words for the numbers and ordinals. This package includes the following date and time styles: itfulltext and it-fulltext-twenty-four. The first style uses a format ``am pm'', the second a format ``24 hours''.

This package provides macros to define and write matrices whose coefficients are given row by row in a list of values separated by commas.

These are font bundles for the Chinese Arphic fonts which work with the CJK package. TrueType versions of these fonts for use with XeLaTeX and LuaLaTeX are provided by the arphic-ttf package.

The package provides Bidi-aware page grid in background. It is based on pagegrid.

This package makes it easy to combine and index individual PDF files into one large PDF file.

This collection of tools consists of: a small package for dealing with duplicate-numbered output pages; newproof, for defining mathematical proof structures; onepagem for omitting the page number in one-page documents and time, which prints a 12-hour format time.

This highly experimental package can be used to add NFSS-declarations of combo fonts to LuaLaTeX documents.

The class offers another modern, neat, design, and provides a simple means of adding an experience timeline'.

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.

This package provides support for the easy inclusion of graphics made by PAW.

pst-lsystem is a PSTricks based package for creating images based on a L-system. A L-system (Lindenmayer system) is a set of rules which can be used to model the morphology of a variety of organisms or fractals like the Kochflake or Hilbert curve.

This package provides a LaTeX environment listing, an alternative to the built-in verbatim environment. The listing environment is tailored for including listings of computer program source code into documents. The main advantages over the original verbatim environment are: environments automatically fixes leading whitespace so that the environment and program listing can be indented with the rest of the document source, and; listing environments may easily be customised and extended.

The schule bundle was built to provide packages and commands that could be useful for documents in German schools. At the moment, its main focus lies on documents for informatics as a school subject. An extension for physics is currently in progress.

For the time being, the whole package splits up into individual packages for informatics (including syntax diagrams, Nassi-Shneiderman diagrams, sequence diagrams, object diagrams, and class diagrams) as well as classes for written exams (tests, quizzes, teaching observations, information sheets, worksheets, and answer keys).
