The hyperref package is used to handle cross-referencing commands in LaTeX to produce hypertext links in the document. The package provides backends for the \special set defined for HyperTeX DVI processors; for embedded pdfmark commands for processing by Acrobat Distiller (dvips and Y&Y's dvipsone); for Y&Y's dviwindo; for PDF control within pdfTeX and dvipdfm; for TeX4ht; and for VTeX's pdf and HTML backends. The package is distributed with the backref and nameref packages, which make use of the facilities of hyperref. The package depends on the author's kvoptions, ltxcmds and refcount packages.
Modern native UTF-8 engines such as XeTeX and LuaTeX need hyphenation patterns in UTF-8 format, whereas older systems require hyphenation patterns in the 8-bit encoding of the font in use (such encodings are codified in the LaTeX scheme with names like OT1, T2A, TS1, OML, LY1, etc). The present package offers a collection of conversions of existing patterns to UTF- 8 format, together with converters for use with 8-bit fonts in older systems. Since hyphenation patterns for Knuthian-style TeX systems are only read at iniTeX time, it is hoped that the UTF-8 patterns, with their converters, will completely supplant the older patterns.
hyphen-base package
Includes Knuth's original hyphen.tex, zerohyph.tex to disable hyphenation, language.us which starts the autogenerated files language.dat and language.def (and default versions of those), etc.
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.
The package provides the switch \ifetex which indicates whether e-TeX is available or not. The package can be loaded as LaTeX package using \usepackage{ifetex} or in plain TeX using \input ifetex. In either case it aborts silently if the \ifetex macro is already defined. The package's test is whether \eTeXversion is defined as a primitive; if it is, the package assumes e-TeX features are available. date: 2011-12-15 16:49:50 +0100
ifmtarg package
The package provides an \ifoddpage conditional to determine if the current page is odd or even. The macro \checkoddpage must be used direct before to check the page number using a label. Two compiler runs are therefore required to achieve correct results. In addition, the conditional \ifoddpageoronside is provided which is also true in oneside mode where all pages use the odd page layout.
This package uses the (La)TeX extension -shell-escape to establish whether the document is being processed on a Windows or on a Unix-like system (Mac OS X, Linux, etc.), or on Cygwin (Unix environment over a windows system). Booleans provided are: \ifwindows, \iflinux, \ifmacosx and \ifcygwin. The package also preserves the output of uname on a Unix-like system, which may be used to distinguish between various classes of Unix systems.
The package, which works both for Plain TeX and for LaTeX, defines the \ifPDFTeX, \ifXeTeX, and \ifLuaTeX conditionals for testing which engine is being used for typesetting. The package also provides the \RequirePDFTeX, \RequireXeTeX, and \RequireLuaTeX commands which throw an error if pdfTeX, XeTeX or LuaTeX (respectively) is not the engine in use.
