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.

The appendix package provides various ways of formatting the titles of appendices. Also (sub)appendices environments are provided that can be used, for example, for per chapter/section appendices. An appendices environment is provided which can be used instead of the \appendix command.

The paralist package provides enumerate and itemize environments that can be used within paragraphs to format the items either as running text or as separate paragraphs with a preceding number or symbol. It also provides compacted versions of enumerate and itemize.

This package provides a LaTeX package for using compound numbers in chemistry documents. It works like \cite and the \thebibliography, using \fcite and \theffbibliography instead. It allows compound names in documents to be numbered and does not affect the normal citation routines.

The package provides a means of sending all LaTeX \newrite, table of contents, and other miscellaneous output via the LaTeX .aux file. The mechanism subverts the mechanism of \newrite, and means there will never be a No room for new \write message.

The package provides macros for typesetting Karnaugh-Maps and Veitch-Charts in a simple and user-friendly way. Karnaugh-Maps and Veitch-Charts are used to display and simplify logic functions manually. These macros can typeset Karnaugh-Maps and Veitch-Charts with up to ten variables.

The package provides a command \patchcommand that can be used to add material at the beginning and the end of the replacement text of an existing macro. It works for macros with any number of normal arguments, including those that were defined with \DeclareRobustCommand.

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 is a small package to create scalebars for maps, diagrams or photos. It was designed for use with cave maps but can be used for anything from showing a scalebar in kilometres for topographic maps to a scalebar in micrometres for an electron microscope image.

The package provides lightweight and robust facilities for creating and managing keys. Its machinery isn't as extensive as that of, e.g., the ltxkeys package, but it is equally robust; ease of use and speed of processing are the design aims of the package.

This package allows you to write \Level 2 {Some heading} instead of the usual \section stuff; the definitions of the levels can then easily be changed. There is a mechanism for shifting all levels. This makes it easy to bundle existing articles into a compilation.

The accfonts package contains three utilities to permit easy manipulation of fonts, in particular the creation of unusual accented characters. mkt1font works on Adobe Type 1 fonts, vpl2vpl works on TeX virtual fonts and vpl2ovp transforms a TeX font to an Omega one.

Bars, in the present context, are lines above and below text that abut with the text. Barred roman numerals are sometimes found in publications. The package provides a function that prints barred roman numerals (converting Arabic numerals if necessary). The package also provides a predicate \ifnumeric.

This package provides a package for typesetting scholarly critical editions, replacing the established ledmac and eledmac packages. It supports indexing by page and by line numbers, and simple tabular- and array-style environments. The package is distributed with the related reledpar package.

The bullcntr package defines the command \bullcntr, which may be thought of as an analogue of the \fnsymbol command: like the latter, it displays the value of a counter lying between 1 and 9, but uses, for the purpose, a regular pattern of bullets.

This package provides a family of 7-bit fonts with a code table designed for setting modern polytonic Greek. The fonts are provided as Metafont source; macros to produce a Greek variant of Plain TeX (including a hyphenation table adapted to the fonts code table) are provided.

The package adds a macro \rgcounts which displays the allocation status of the TeX registers. The display is written into the .log file as it is a bit verbose. An automatic call to \rgcounts is done at \begin{document} and \end{document}.

The package provides an \AtAppendix command to add code to a hook that is executed when \appendix is called by the user. Additionally, a TeX conditional \ifappendix and a LaTeX-style conditional \IfAppendix are provided to check if \appendix has already been called.

The lettrine package supports various dropped capitals styles, typically those described in the French typographic books. In particular, it has facilities for the paragraph text's left edge to follow the outline of capitals that have a regular shape (such as A and V).

This package provides the \setcounterref and \addtocounterref commands which use the section (or other) number from the reference as the value to put into the counter. It also provides \setcounterpageref and \addtocounterpageref that do the corresponding thing with the page reference of the label.

The setspace package provides support for setting the spacing between lines in a document. Package options include singlespacing, onehalfspacing, and doublespacing. Alternatively the spacing can be changed as required with the \singlespacing, \onehalfspacing, and \doublespacing commands. Other size spacings also available.

This package allows you to use alphanumeric section numbering. Its output is similar to alphanum, but you can use the standard LaTeX sectioning commands, so that it is possible to switch numbering schemes easily. Greek letters, double letters (bb) and different delimiters around them are supported.

The package provides techniques for adding flip book animations in the corner of your LaTeX documents (using images or ASCII art). Animations are defined as a set of numbered files (e.g., im1.pdf, im2.pdf, ...). The package relies on fancyhdr to control the corners.

The package provides commands for typesetting number lines (coordinate axes), coordinate systems and grids in the picture environment. The package may be integrated with other drawing mechanisms: the documentation shows examples of drawing graphs (coordinate tables created by Maple), using the eepic package's drawing capabilities.
