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.

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.

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}.

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.

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 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.

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 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 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 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.

The hypdvips package fixes some problems when using hyperref with Dvips. It also adds support for breaking links, file attachments, embedded documents and different types of GoTo-links. The cooperation of hyperref with cleveref is improved, which in addition allows an enhanced back-referencing system.

This package produces a wide page layout for documents that use A4 paper size. Moreover, LayAureo provides both a simple hook for leaving an empty space, which is required if pages are bundled by a press binding, and an option called big that forces typearea to become maximum.

The LaTeX internal command \@finalstrut is used automatically used at the end of footnote texts to insert a strut to avoid mis-spacing of multiple footnotes. Unfortunately the command can cause a blank line at the end of a footnote. The package provides a solution to this problem.

The package offers enhancements for theorem-like environments: easier control of layout; proper placement of endmarks even when the environment ends with \end{enumerate} or \end{displaymath} (including support for amsmath displayed-equation environments); and support for making a list of theorems, analogous to \listoffigures.

Exceptions for American English hyphenation patterns are occasionally published in the TeX User Group journal TUGboat. This bundle provides alternative Perl and Bourne shell scripts to convert the source of such an article into an exceptions file, together with a recent copy of the article and machine-readable files.

xcharter repackages Bitstream Charter with an extended set of features. The extension provides small caps, oldstyle figures and superior figures in all four styles, accompanied by LaTeX font support files. The fonts themselves are provided in both Adobe Type 1 and OTF formats, with supporting files as necessary.

The package provides macros for typesetting natural deduction proofs in Fitch style, with subproofs indented and offset by scope lines. The proofs from use of the package are in the format used in the textbook Language, Proof, and Logic by Dave Barker-Plummer, Jon Barwise, and John Etchemendy.

This package enables users to specify in their sources the following settings on the PDF document to output: PDF version (1.4, 1.5 etc.); whether or not to compress streams; whether or not to use object streams. This package supports all major PDF-output engines and dvipdfmx.

The hfoldsty package provides virtual fonts for using old-style figures with the European Computer Modern fonts. It does a similar job as the eco package but includes a couple of improvements, i.e., better kerning with guillemets, and support for character protruding using the pdfcprot package.

The ragged2e package defines new commands \Centering, \RaggedLeft, and \RaggedRight and new environments Center, FlushLeft, and FlushRight, which set ragged text and are easily configurable to allow hyphenation (the corresponding commands in LaTeX, all of whose names are lower-case, prevent hyphenation altogether).

This package extends the \newtheorem command with a new command, \newshadetheorem, which can produce theorem statement in a shaded box. It supports all the options of \newtheorem.

However, this package is considered as obsolete by its author. Users are generally recommended, therefore, to use mdframed instead.

This is a Lua(La)TeX macro package that supports typesetting Korean documents including Old Hangul texts. As LuaTeX has opened up access to almost all the hidden routines of TeX engine, users can obtain more beautiful outcome using this package rather than other Hangul macros operating on other engines.
