The original WEB system by Donald Knuth has the macros webmac.tex that produce DVI output only; for historic reasons, it will never be modified (apart from catastrophic errors). Han The Thanh has modified these macros in his pdfwebmac.tex for PDF output (only) with pdfTeX. Jonathan Kew's XeTeX has similar macros xewebmac.tex by Khaled Hosny that modify webmac.tex for PDF output; these macros can only be used with a specific TeX engine each. The present pwebmac package integrates these three WEB macro files similar to cwebmac.tex in Silvio Levy's and Don Knuth's CWEB system, so pwebmac.tex can be used with Plain TeX, pdfTeX, and XeTeX alike.

Its initial application is the production of PDF and HINT files for all major WEB programs for TeX and friends. For this purpose, the shell script makeall was whipped together; it provides various command line options and works around several quirks in the WEB sources.

WEB programmers who want to use pwebmac.tex instead of the default webmac.tex in their programs have to change the first line in the TeX file created by weave. From there, all depends on the TeX engine you use.

It is often desirable to take an existing PDF and easily add annotations or text overlaying the PDF. This might arise if you wish to add comments to a PDF, fill in a PDF form, or add text to a PDF where space has been left for notes. This package provides a simple interface to do this without having to resort to inserting one page at a time. Some or all of the pages of the PDF can be included and not all pages of the PDF need have overlayed text. It is also possible to include text between pages of the PDF. Another advantage of this package is that the overlayed text can be set as normal flowing from one page to another or with manual page breaks if you wish. It is also possible to use any standard method to position text at arbitrary places on a given page.

Paper submissions to journals are usually accompanied by a cover letter. This package provides a LaTeX class and a template for such a cover letter with the following main features:

• minimalistic design,

• custom image,

• pre-defined commands for journal name, author, date, etc.

• many macros contained in this package speed up the process of preparing the necessary ingredients for the cover letter;

• macros for recommending up to three reviewers and editors;

• ORCID logo and link to the submitting author's ORCID page;

• controls for adding a ``conflict of interest'' statement and declaration;

• custom greeting;

• predefined valedictions for different types of submissions.

The package patches a few commands of the LaTeX2e kernel and the amsmath and mathtools packages to be more compatible with the LuaTeX engine. It is only meaningful for LuaLaTeX documents containing mathematical formulas, and does not exhibit any new functionality. The fixes are mostly moved from the unicode-math package to this package since they are not directly related to Unicode mathematics typesetting.

The original grffile package extended the file name processing of the graphics package to support a larger range of file names. The base LaTeX code now supports multiple dots and spaces, and this package by default is a stub that just loads graphicx.

This package provides an environment to create grids (type 5x5 or Seyes or Ruled) and commands to write texts right on the lines.

This package provides the PlayFairDisplay family of fonts, designed by Claus Eggers Sorensen, for use with LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX. PlayFairDisplay is well suited for titling and headlines. It has an extra large x-height and short descenders. It can be set with no leading if space is tight, for instance in news headlines, or for stylistic effect in titles. Capitals are extra short, and only very slightly heavier than the lowercase characters. This helps achieve a more even typographical colour when typesetting proper nouns and initialisms.

The package provides a custom citation-style for typesetting a German law thesis with LaTeX.

This bundled is aimed at producing undergraduate students final work or report at UFRGS/EE (Engineering School at the Federal University of Rio Grande do Sul), closely following ABNT rules (Brazilian Association for Technical Norms). It is composed of a main class, ufrgscca, and a set of auxiliary packages, some of which can be used independently.

This package provides a collection of input encodings, font encodings and font definition files for the Hebrew language.

Porson is an elegant Greek font, originally cut at the turn of the 19th Century in England. The present version has been provided by the Greek Font Society. The font supports the Greek alphabet only. LaTeX support is provided, using the LGR encoding.

The package provides emulation of pdfTeX primitives for LuaTeX v0.85+.

This package provides the binary for texlive-xetex.

The package harmony.sty helps typesetting harmony symbols for musicology.

This package provides an extended version of the plain TeX format, adding support for bibliographies, tables of contents, enumerated lists, verbatim input of files, numbered equations, tables, two-column output, footnotes, hyperlinks in PDF output and commutative diagrams. Eplain can also load some of the more useful LaTeX packages, notably graphics, graphicx (an extended version of graphics), color, autopict (a package instance of the LaTeX picture code), psfrag, and url.

Occasional Documents appear, that use graphics generated by TeXcad from the EmTeX distribution. These documents often use the \emline macro, which produced lines at an arbitrary orientation. The present package emulates the macro, using TikZ.
