Section +\ref{sec:tl-coll-dists} briefly describes the contents of this \DVD. +Both \TL{} and the \TK{} are cooperative efforts by the \TeX{} user +groups. This document mainly describes \TL{} itself. + +\TL{} includes executables for \TeX{}, \LaTeXe{}, \ConTeXt, +\MF, \MP, \BibTeX{} and many other programs; an extensive collection +of macros, fonts and documentation; and support for typesetting in +many different scripts from around the world. + +\TL{} packages are regularly updated from +\acro{CTAN}: \url{http://www.ctan.org}. + +For a brief summary of the major changes in this edition of \TL{}, +see the end of the document, section~\ref{sec:history} +(\p.\pageref{sec:history}). + +\subsection{Operating system support} +\label{sec:os-support} + +\TL{} contains binaries for many Unix-based architectures, +including \MacOSX. The included sources should enable installation +on platforms for which we do not have binaries. + +As to Windows: only Windows 2000 and later are supported. Windows +9\textit{x}, ME and NT have been dropped. Because of this +change, Windows requires much less special treatment compared to +the Unix systems. There are no 64-bit executables for Windows, but the +32-bit executables should run on 64-bit systems. + +See section~\ref{sec:tl-coll-dists} for alternate solutions +for Windows and \MacOSX. + +\subsection{Basic installation of \protect\TL{}} +\label{sec:basic} + +You can install \TL{} either from \DVD{} or over the Internet. The net +installer itself is small, and downloads everything requested from the +Internet. The net installer is an attractive option if you need only a +fraction of the complete \TL. + +The \DVD{} installer lets you install to a local disk, but you can +also run \TL{} directly from the \DVD{} (or from a \DVD{} image, if +your system supports that). + +\noindent This is described in the +installation sections following, but here is a quick start: + +\begin{itemize*} + +\item The installation script is named \filename{install-tl}. It can + operate in both a \GUI{} mode (default for Windows) and + a text mode (default for everything else). You can force one mode or + the other with the options \code{-gui} and \code{-no-gui}, respectively. + +\item One of the installed items is a new program, the `\TL\ Manager', + named \prog{tlmgr}. Like the installer, it can be used in both \GUI{} + mode and in text mode. You can use it to install and uninstall + packages and do various configuration tasks. + +\end{itemize*} + + +\subsection{Getting help} +\label{sec:help} + +The \TeX{} community is both active and friendly, and most serious +questions end up getting answered. However, the support is informal, +done by volunteers and casual readers, so it's especially important that +you do your homework before asking. (If you prefer guaranteed +commercial support, you can forego \TL{} completely and purchase a +vendor's system; \url{http://tug.org/interest.html#vendors} has a list.) + +Here is a list of resources, approximately in the order we recommend +using them: + +\begin{description} +\item [Getting Started] If you are new to \TeX, the web page +\url{http://tug.org/begin.html} gives a brief introduction to the system. + +\item [\TeX{} \acro{FAQ}] The \TeX{} \acro{FAQ} is a huge compendium + of answers to all sorts of questions, from the most basic to the + most arcane. It is included on \TL{} in + \OnCD{texmf-doc/doc/english/FAQ-en/html/index.html}, and is available + on the Internet through \url{http://www.tex.ac.uk/faq}. Please + check here first. + +\item [\TeX{} Catalogue] If you are looking for a specific package, +font, program, etc., the \TeX{} Catalogue is the place to look. It is a +huge collection of all \TeX{}-related items. See +\url{http://www.ctan.org/help/Catalogue/}. + +\item [\TeX{} Web Resources] The web page +\url{http://tug.org/interest.html} has many \TeX{}-related links, in +particular for numerous books, manuals, and articles on all aspects of +the system. + +\item [support archives] The two principal support forums are the +Usenet newsgroup \url{news:comp.text.tex} and the mailing list +\email{texhax@tug.org}. Their archives have years of past +questions and answers for your searching pleasure, via +\url{http://groups.google.com/group/comp.text.tex/topics} and +\url{http://tug.org/mail-archives/texhax}, respectively. And a general web +search, for example on \url{http://google.com}, never hurts. + +\item [asking questions] If you cannot find an answer, you can post to +\dirname{comp.text.tex} through Google or your newsreader, or to +\email{texhax@tug.org} through email. But before you post, +\emph{please} read this \acro{FAQ} entry, to maximize +your chances of getting a useful answer: +\url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=askquestion}. + +\item [\TL{} support] If you want to report a bug or have +suggestions or comments on the \TL{} distribution, installation, or +documentation, the mailing list is \email{tex-live@tug.org}. However, +if your question is about how to use a particular program included in +\TL{}, please write to that program's maintainer or +mailing list. Often running a program with the \code{-{}-help} option +will provide a bug reporting address. + +\end{description} + +The other side of the coin is helping others who have questions. Both +\dirname{comp.text.tex} and \code{texhax} are open to anyone, so feel +free to join, start reading, and help out where you can. + + +% don't use \TL so the \uppercase in the headline works. Also so +% tex4ht ends up with the right TeX. Likewise the \protect's. +\section{Overview of \protect\TeX\protect\ Live} +\label{sec:overview-tl} + +This section describes the contents of \TL{} and the \TK{} of which it +is a part. + +\subsection{The \protect\TeX\protect\ Collection: \TL, pro\TeX{}t, Mac\TeX} +\label{sec:tl-coll-dists} + +The \TK{} \DVD{} comprises the following: + +\begin{description} + +\item [\TL] A complete \TeX{} system which can be run live or + installed to disk. + +\item [Mac\TeX] for \MacOSX, this adds a native \MacOSX\ installer and other +Mac applications to \TL{}. Its home page is +\url{http://www.tug.org/mactex/}. + +\item [pro\TeX{}t] An enhancement of the \MIKTEX\ distribution for Windows, +\ProTeXt\ adds a few extra tools to \MIKTEX, and simplifies +installation. It is entirely independent of \TL{}, and has its own +installation instructions. The \ProTeXt\ home page is +\url{http://tug.org/protext}. + +\item [CTAN] A snapshot of the \CTAN{} repository. + +\item [\texttt{texmf-extra}] A directory with assorted additional packages. + +\end{description} + +\CTAN{}, \pkgname{protext}, and \dirname{texmf-extra} do not +necessarily follow the same copying conditions as \TL{}, so be careful +when redistributing or modifying. + + +\subsection{Top level \TL{} directories} +\label{sec:tld} + +Here is a brief listing and description of the top level directories in +the \TL{} distribution. On the \pkgname{live} \DVD, the entire \TL{} +hierarchy is in a subdirectory \dirname{texlive}, not at the top +level of the disc. + +\begin{ttdescription} +\item[bin] The \TeX{} system programs, arranged by platform. +% +\item[readme.html] Web pages with a quick introduction and useful links, +in various languages. +% +\item[source] The source to all included programs, including the main \Webc{} + \TeX{} and \MF{} distributions. +% +\item[support] Various auxiliary packages and programs. These are + \emph{not} installed automatically. This includes + assorted editors and \TeX\ shells. +% +\item[texmf] See \dirname{TEXMFMAIN} below. +% +\item[texmf-dist] See \dirname{TEXMFDIST} below. +% +\item[texmf-doc] Tree for self-contained pure documentation, arranged by + language. +% +\item[tlpkg] Scripts, programs and data for managing the + installation. It also contains private copies of + Perl and Ghostscript for Windows, which are invisible outside \TL, + and a new Windows PostScript viewer PSView. +\end{ttdescription} + +In addition to the directories above, the installation scripts and +\filename{README} files (in various languages) are at the top level of +the distribution. + +The \dirname{texmf-doc} directory contains documentation which does +not belong to any particular package or program. The documentation +for the programs (manuals, man pages, Info files) is in +\dirname{texmf/doc}. The documentation for \TeX\ packages and +formats is in \dirname{texmf-dist/doc}. You can use the +\cmdname{texdoc} or \cmdname{texdoctk} programs to find any +documentation wherever it is located. The comprehensive links in +the top-level file \OnCD{doc.html} may also be helpful. + +This \TL\ documentation itself is in \dirname{texmf-doc} and is +available in several languages: + +\begin{itemize*} +\item{Simplified Chinese:} \OnCD{texmf-doc/doc/chinese/texlive-zh-cn} +\item{Czech/Slovak:} \OnCD{texmf-doc/doc/czechslovak/texlive-cz} +\item{English:} \OnCD{texmf-doc/doc/english/texlive-en} +\item{French:} \OnCD{texmf-doc/doc/french/texlive-fr} +\item{German:} \OnCD{texmf-doc/doc/german/texlive-de} +\item{Polish:} \OnCD{texmf-doc/doc/polish/texlive-pl} +\item{Russian:} \OnCD{texmf-doc/doc/russian/texlive-ru} +\end{itemize*} + +\subsection{Overview of the predefined texmf trees} +\label{sec:texmftrees} + +This section lists all predefined variables specifying the texmf trees +used by the system, and their intended purpose, and the default +layout of a \TL{} system. The command \texttt{texconfig conf} shows +you the values of these variables, so that you can easily find out +how they map to directory names in your installation. + +\begin{ttdescription} +\item [TEXMFMAIN] The tree which holds vital parts of the system + such as helper scripts (e.g., \verb+web2c/mktexdir+) and other + support files and their documentation. Does not include + \TeX\ formats and packages. +\item [TEXMFDIST] The tree which holds the main set of macro packages, + fonts, etc., as originally distributed. +\item [TEXMFLOCAL] The tree which administrators can use for system-wide + installation of additional or updated macros, fonts, etc. +\item [TEXMFHOME] The tree which users can use for their own individual + installations of additional or updated macros, fonts, etc. + The expansion of this variable dynamically adjusts for each user to + their own individual directory. +\item [TEXMFCONFIG] The tree used by the utilities + \verb+texconfig+, \verb+updmap+, and \verb+fmtutil+ to store modified + configuration data. Under \envname{TEXMFHOME} by default. +\item [TEXMFSYSCONFIG] The tree used by the utilities + \verb+texconfig-sys+, \verb+updmap-sys+, and \verb+fmtutil-sys+ to + store modified configuration data. +\item [TEXMFVAR] The tree used by \verb+texconfig+, \verb+updmap+ and + \verb+fmtutil+ to store (cached) runtime data such as format files and + generated map files. Under \envname{TEXMFHOME} by default. +\item [TEXMFSYSVAR] The tree used by \verb+texconfig-sys+, + \verb+updmap-sys+ and \verb+fmtutil-sys+, and also by \verb+tlmgr+, to + store (cached) runtime data such as format files and generated map files. +\end{ttdescription} + +\noindent +The default layout is: +\begin{description} + \item[system-wide root] can span multiple \TL{} releases: + \begin{ttdescription} + \item[2007] A previous release. + \begin{ttdescription} + \item [...] + \end{ttdescription} + \item[2008] The current release. + \begin{ttdescription} + \item [bin] ~ + \begin{ttdescription} + \item [i386-linux] \GNU/Linux binaries + \item [...] + \item [universal-darwin] \MacOSX binaries + \item [win32] Windows binaries + \end{ttdescription} + \item [texmf] This is \envname{TEXMFMAIN}. + \item [texmf-dist] \envname{TEXMFDIST} + \item [texmf-doc] \envname{TEXMFDOC} + \item [texmf-var] \envname{TEXMFSYSVAR} + \item [texmf-config] \envname{TEXMFSYSCONFIG} + \end{ttdescription} + \item [texmf-local] \envname{TEXMFLOCAL}, intended to be + retained from release to release. + \end{ttdescription} + \item[user's home] (\texttt{\$HOME} or + \texttt{\%USERPROFILE\%}) + \begin{ttdescription} + \item[.texlive2007] Privately generated and configuration data + for a previous release. + \item[.texlive2008] Privately generated and configuration data + for the current release. + \begin{ttdescription} + \item [texmf-var] \envname{TEXMFVAR} + \item [texmf-config] \envname{TEXMFCONFIG} + \end{ttdescription} + \item[texmf] \envname{TEXMFHOME} Personal macros. + \textit{etc.} + \end{ttdescription} +\end{description} + + +\subsection{Extensions to \protect\TeX} +\label{sec:tex-extensions} + +\TeX{} itself is frozen, apart from rare bug fixes. It is still present +in \TL\ as the program \prog{tex}, and will remain so in the +foreseeable future. \TL{} contains several extended versions of \TeX: + +\begin{description} + +\item [\eTeX] adds a set of new primitives +\label{text:etex} (related to macro expansion, character scanning, +classes of marks, additional debugging features, and more) and the +\TeXXeT{} extensions for bidirectional typesetting. In default mode, +\eTeX{} is 100\% compatible with ordinary \TeX. See +\OnCD{texmf-dist/doc/etex/base/etex_man.pdf}. + +\item [pdf\TeX] builds on the \eTeX\ extensions, adding support for +writing \acro{PDF} output as well as \dvi{}. This is the program +invoked for most formats, e.g., \prog{etex}, \prog{latex}, +\prog{pdflatex}. See \url{http://www.pdftex.org/}. +\OnCD{texmf-dist/doc/pdftex/manual/pdftex-a.pdf} for the manual, and +\OnCD{texmf-dist/doc/pdftex/manual/samplepdf/samplepdf.tex} for example usage +of some of its features. + +\item [Lua\TeX] is the designated successor of pdf\TeX, with which it +is intended to be backward-compatible. It should also supersede Aleph, +see below. The incorporated Lua interpreter (see +\url{http://www.lua.org/}) enables elegant solutions for many thorny +\TeX{} problems. When called as \filename{texlua}, it functions as a +standalone Lua interpreter, and is already used as such within \TL. See +\url{http://www.luatex.org/} and +\OnCD{texmf-dist/doc/luatex/luatexref-t.pdf}. + +\item [\XeTeX] adds support for Unicode input and OpenType- and system +fonts, implemented using standard third-party libraries. See +\url{http://scripts.sil.org/xetex}. + +\item [\OMEGA\ (Omega)] is based on Unicode (16-bit characters), thus +supports working with almost all the world's scripts simultaneously. It +also supports so-called `\OMEGA{} Translation Processes' (\acro{OTP}s), +for performing complex transformations on arbitrary input. See +\OnCD{texmf-dist/doc/omega/base/doc-1.8.tex} (not completely up-to-date). + +\item [Aleph] combines the \OMEGA\ and \eTeX\ extensions. +See \OnCD{texmf-dist/doc/aleph/base} for some minimal documentation. + +\end{description} + + +\subsection{Other notable programs in \protect\TL} + +Here are a few other commonly-used programs included in \TL{}: + +\begin{cmddescription} + +\item [bibtex] bibliography support. + +\item [makeindex] index support. + +\item [dvips] convert \dvi{} to \PS{}. + +\item [xdvi] \dvi{} previewer for the X Window System. + +\item [dvilj] \dvi{} drive for the HP LaserJet family. + +\item [dv2dt, dt2dv] convert \dvi{} to/from plain text. + +\item [dviconcat, dviselect] cut and paste pages +from \dvi{} files. + +\item [dvipdfmx] convert \dvi{} to \acro{PDF}, an alternative approach +to pdf\TeX\ (mentioned above). See the \pkgname{ps4pdf} and +\pkgname{pdftricks} packages for still more alternatives. + +\item [psselect, psnup, \ldots] \PS{} +utilities. + +\item [lacheck] \LaTeX{} syntax checker. + +\item [texexec, texmfstart] Con\TeX{}t and \acro{PDF} processor. + +\item [tex4ht] \TeX{} to \acro{HTML} (and \acro{XML} and more) converter. + +\end{cmddescription} + + +\subsection{Fonts in \protect\TL} +\label{sec:tl-fonts} + +\TL{} comes with many high-quality scalable fonts. See +\url{http://tug.org/fonts} and +\OnCD{texmf-doc/doc/english/free-math-font-survey}. + + + +\section{Installation} +\label{sec:install} + +\subsection{Starting the installer} +\label{sec:inst-start} + +To start with, get the \TK{} \DVD{} or download the \TL{} net installer, +and locate the installer script: \filename{install-tl} for Unix, +\filename{install-tl.bat} for Windows. + +\begin{description} +\item [Net installer:] Download from \CTAN, under +\dirname{systems/texlive/tlnet}; the url +\url{http://mirror.ctan.org/systems/texlive/tlnet} will automatically +redirect to a nearby, up-to-date, mirror. You can retrieve either +\filename{install-tl.zip} which can be used under Unix and Windows and +\filename{install-unx.tar.gz} which is considerably smaller, for Unix +only. After unpacking, \filename{install-tl} and +\filename{install-tl.bat} will be in the \dirname{install-tl} +subdirectory. + +\item [\TeX{} Collection \DVD:] go to its \dirname{texlive} +subdirectory. Under Windows, the installer should start automatically +when you insert the \DVD. You can get the \DVD\ by becoming a member of +a \TeX\ user group (highly recommended, +\url{http://tug.org/usergroups.html}), or purchasing it separately +(\url{http://tug.org/store}), or burning your own from the \ISO\ +image (\url{http://tug.org/texlive/acquire.html}). + +\end{description} +The following sections explain in more detail. + +\subsubsection{Unix} + +\begin{figure}[tb] +\begin{boxedverbatim} +======================> TeX Live installation procedure <===================== + +=======> Note: Letters/digits in <angle brackets> indicate menu items <======= +=======> for commands or configurable options <======= + + + Detected platform: Intel x86 with GNU/Linux + + <B> binary systems: 1 out of 16 + + <S> Installation scheme (scheme-full) + + Customizing installation scheme: + <C> standard collections + <L> language collections + 83 collections out of 84, disk space required: 1666 MB + + <D> directories: + TEXDIR (the main TeX directory): + !! default location: /usr/local/texlive/2008 + !! is not writable, please select a different one! + TEXMFLOCAL (directory for site-wide local files): + /usr/local/texlive/texmf-local + TEXMFSYSVAR (directory for variable and automatically generated data): + /usr/local/texlive/2008/texmf-var + TEXMFSYSCONFIG (directory for local config): + /usr/local/texlive/2008/texmf-config + TEXMFHOME (directory for user-specific files): + ~/texmf + + <O> options: + [ ] use letter size instead of A4 by default + [X] create all format files + [X] install macro/font doc tree + [X] install macro/font source tree + [ ] create symlinks in standard directories + + <V> Install for running from DVD + +Other actions: + <I> start installation to HD + <H> help + <Q> quit + +Enter command: +\end{boxedverbatim} +\caption{Main text installer screen (\GNU/Linux)}\label{fig:text-main} +\end{figure} + +\begin{figure}[tb] +\tlpng{install-w32-main}{\linewidth} +\caption{Main \GUI{} installer screen (Windows)}\label{fig:gui-main} +\end{figure} + +\noindent +Below, \texttt{>} denotes the shell prompt; user input is +\Ucom{\texttt{bold}}. +Starting in a terminal window on a Unix-compatible system, the simplest +way: +\begin{alltt} +> \Ucom{cd /path/to/installer} +> \Ucom{perl install-tl} +\end{alltt} +(Or you can invoke \Ucom{perl /path/to/installer/install-tl}, or +\Ucom{./install-tl} if it stayed executable, etc.; we won't repeat all +these variations.) + +To install in \GUI\ mode (you'll need the \dirname{Perl/TK} module), use: +\begin{alltt} +> \Ucom{perl install-tl -gui} +\end{alltt} + +For a complete listing of the various options: +\begin{alltt} +> \Ucom{perl install-tl -help} +\end{alltt} + +\textbf{Warning about Unix permissions:} Your \code{umask} at the time +of installation will be respected by the \TL{} installer. Therefore, if +you want your installation to be usable by users other than you, make +sure your setting is sufficiently permissive, for instance, \code{umask +002}. For more information about \code{umask}, consult your system +documentation. + + +\subsubsection{Mac\,OS\,X} + +As mentioned in section~\ref{sec:tl-coll-dists}, a separate distribution +is prepared for \MacOSX, named Mac\TeX\ (\url{http://tug.org/mactex}). +We recommend using the native Mac\TeX\ installer instead of the \TL\ +installer on \MacOSX, because the native installer can make a few +Mac-specific adjustments, in particular to allow easily switching +between the various \TeX\ distributions for \MacOSX\ (Mac\TeX, gw\TeX, +Fink, MacPorts, \ldots). + +Mac\TeX\ is firmly based on \TL, and the main \TeX\ trees are precisely +the same. It does add a few extra folders with Mac-specific +documentation and applications. + + +\subsubsection{Windows} + +If you are using the net installer, or the \DVD\ installer failed to +start automatically, double-click \filename{install-tl.bat}. + +You can also start the installer from the command-prompt. Below, +\texttt{>} denotes the prompt; user input is \Ucom{\texttt{bold}}. If +you are in the installer directory, run just: +\begin{alltt} +> \Ucom{install-tl} +\end{alltt} + +Or you can invoke it with an absolute location, such as: +\begin{alltt} +> \Ucom{D:\bs{}texlive\bs{}install-tl} +\end{alltt} +for the \TK\ \DVD, supposing that \dirname{D:} is the optical drive. + +To install in text mode, use: +\begin{alltt} +> \Ucom{install-tl -no-gui} +\end{alltt} + +For a complete listing of the various options: +\begin{alltt} +> \Ucom{install-tl -help} +\end{alltt} + +\subsubsection{The text installer} + +Figure~\ref{fig:text-main} displays the main text mode screen under +Unix. + +This is only a command-line installer; there is no cursor support at +all. For instance, you cannot tab around checkboxes or input fields. +You just type something (case-sensitive) at the prompt and press the +Enter key, and then the entire terminal screen will be rewritten, with +adjusted content. + +The text installer interface is this primitive for a reason: it +is designed to run on as many platforms as possible, even with a +very barebones Perl (for Windows, a Perl subset is included). + +\subsubsection{The graphical installer} + +Figure~\ref{fig:gui-main} displays the graphical installer under +Windows. Most differences in available options are due to this +screenshot being from Windows, and the previous text screen being +from \GNU/Linux. + +\subsection{Running the installer} +\label{sec:runinstall} + +The installer is intended to be mostly self-explanatory. Still, a few +quick notes about the various options and submenus: + +\subsubsection{Binary systems menu (Unix only)} +\label{sec:binary} + +\begin{figure}[tbh] +\begin{boxedverbatim} +Available sets of binaries: +=============================================================================== + + a [ ] alpha-linux DEC Alpha with GNU/Linux + b [ ] amd64-freebsd x86_64 with FreeBSD + c [ ] hppa-hpux HP-UX + d [ ] i386-freebsd Intel x86 with FreeBSD + e [X] i386-linux Intel x86 with GNU/Linux + f [ ] i386-openbsd Intel x86 with OpenBSD + g [ ] i386-solaris Intel x86 with Sun Solaris + h [ ] mips-irix SGI IRIX + i [ ] powerpc-aix PowerPC with AIX + j [ ] powerpc-linux PowerPC with GNU/Linux + k [ ] sparc-linux Sparc with GNU/Linux + l [ ] sparc-solaris Sparc with Solaris + m [ ] universal-darwin universal binaries for MacOSX/Darwin + o [ ] win32 Windows + p [ ] x86_64-linux x86_64 with GNU/Linux +\end{boxedverbatim} +\caption{Binaries menu}\label{fig:bin-text} +\end{figure} + +Figure~\ref{fig:bin-text} displays the text mode binaries menu. By +default, only the binaries for your current platform will be installed. +From this menu, you can select installation of binaries for other +architectures as well. This can be useful if you are sharing a \TeX\ +tree across a network of heterogenous machines, or for a dual-boot +system. + +\subsubsection{Selecting what is going to be installed} +\label{sec:components} + +\begin{figure}[tbh] +\begin{boxedverbatim} +Select a scheme: +=============================================================================== + + a [ ] TeX Live basic scheme + b [ ] TeX Live scheme for ConTeXt + c [X] TeX Live full scheme + d [ ] GUST TeX Live scheme + e [ ] GUTenberg TeX Live scheme + f [ ] TeX Live medium scheme + g [ ] TeX Live minimal scheme + h [ ] TeX Live for Omega users + i [ ] teTeX scheme + j [ ] XML typesetting scheme +\end{boxedverbatim} +\caption{Scheme menu}\label{fig:scheme-text} +\end{figure} + +Figure~\ref{fig:scheme-text} displays the \TL\ scheme menu; from here, +you choose a ``scheme'', which is an overall set of package collections. +The default \optname{full} scheme installs everything available, but you +can also choose the \optname{basic} scheme for a small system, +\optname{minimal} for testing purposes, and \optname{medium} or +\optname{teTeX} to get something in between. There are also various +specialized and country-specific schemes. + +\begin{figure}[tbh] +\tlpng{stdcoll}{.7\linewidth} +\caption{Collections menu (Linux)}\label{fig:collections-gui} +\end{figure} + +You can refine your scheme selection with the `standard collections' and +`language collections' menus (figure~\ref{fig:collections-gui}, shown in +\GUI\ mode for a change). + +Collections are one level more detailed than schemes\Dash in essence, a +scheme consists of several collections, a collection consists of one or +more packages, and a package (the lowest level grouping in \TL) contains +the actual \TeX\ macro files, font files, and so on. + +If you want more control than the collection menus provide, you can use +the \prog{tlmgr} program after installation (see +section~\ref{sec:tlmgr}); using that, you can control the installation +at the package level. + +\subsubsection{Directories} +\label{sec:directories} + +The default layout is described in section~\ref{sec:texmftrees}, +\p.\pageref{sec:texmftrees}. The default location of +\dirname{TEXDIR} is different between Windows +(|%PROGRAMFILES%\texlive\2008|) and Unix +(\dirname{/usr/local/texlive/2008}). + +The main reason to change this default is if you lack write permission +for the default location. You don't have to be root or adminstrator to +install \TL, but you do need write access to the target directory. + +A logical alternate choice is a directory under your home directory, +especially if you will be the sole user. Use +`|~|' to indicate this, as in `|~/texlive/2008|'. + +We recommend including the year in the name, to enable keeping different +releases of \TL{} side by side. (You may wish to make a +version-independent name such as \dirname{/usr/local/texlive-cur} via a +symbolic link, which you can then update after testing the new release.) + +Changing \dirname{TEXDIR} in the installer will also change +\dirname{TEXMFLOCAL}, \dirname{TEXMFSYSVAR} and +\dirname{TEXMFSYSCONFIG}. + +\dirname{TEXMFHOME} is the recommended location for personal +macro files or packages. The default value is |~/texmf|. In +contrast to \dirname{TEXDIR}, here a |~| is preserved in the +newly-written configuration files, since it usefully refers to the home +directory of each individual running \TeX. It expands to +\dirname{$HOME} on Unix and \verb|%USERPROFILE%| on Windows. + +\subsubsection{Options} +\label{sec:options} + +\begin{figure}[tbh] +\begin{boxedverbatim} +<P> use letter size instead of A4 by default: [ ] +<F> create all format files: [X] +<D> install font/macro doc tree: [X] +<S> install font/macro source tree: [X] +<L> create symlinks in standard directories: [ ] + binaries to: + manpages to: + info to: +\end{boxedverbatim} +\caption{Options menu (Unix)}\label{fig:options-text} +\end{figure} + +Figure~\ref{fig:options-text} displays the text mode options menu. +Three of the options here need mentioning: + +\begin{description} +\item[use letter size instead of A4 by default:] The usual default paper + size selection. Of course, individual documents can specify a specific + paper size, if desired. + +\item[create all format files:] Although unnecessary format files + take time to generate and disk space to store, it is still recommended + to leave this option checked: if you don't, then format files will be + generated in people's private \dirname{TEXMFVAR} tree as they are + needed. In that location, they will not be updated automatically if + (say) binaries or hyphenation patterns are updated in the + installation, and thus could end up with incompatible format files. + +\item[create symlinks in standard directories] (Unix only): + This option bypasses the need to change environment + variables. Without this option, \TL{} directories have to be added + to \envname{PATH}, \envname{MANPATH} and \envname{INFOPATH}. You will + need write permissions to the target directories. It is not + advisable to overwrite a \TeX\ system that came with your system + with this option. It is intended primarily for creating the links + in standard directories that are known to users, such as + \dirname{/usr/local/bin}, which don't already contain any + \TeX\ files. +\end{description} + +Now when all these settings are to your liking, you can type `I' to +start the installation process. When it is done, skip to +section~\ref{sec:postinstall} to read what else needs to be done, if +anything. + +\htmlanchor{runfromdvd} +\subsubsection{Set up for running from DVD{} (text mode only)} +\label{sec:fromdvd} + +Type `|V|' to select this option. This changes the main menu into something +like figure~\ref{fig:main-fromdvd}. +\begin{figure}[tbh] +\begin{boxedverbatim} +======================> TeX Live installation procedure <===================== + +=======> Note: Letters/digits in <angle brackets> indicate menu items <======= +=======> for commands or configurable options <======= + + <D> directories: + TEXDIRW (Writable root): + !! default location: /usr/local/texlive/2008 + !! is not writable, please select a different one! + TEXMFLOCAL (directory for site-wide local files): + /usr/local/texlive/texmf-local + TEXMFSYSVAR (directory for variable and automatically generated data): + /usr/local/texlive/2008/texmf-var + TEXMFSYSCONFIG (directory for local config): + /usr/local/texlive/2008/texmf-config + TEXMFHOME (directory for user-specific files): + ~/texmf + + <O> options: + [ ] use letter size instead of A4 by default + [X] create all format files + + <V> set up for installing to hard disk + +Other actions: + <I> start installation for running from DVD + <H> help + <Q> quit +\end{boxedverbatim} +\caption{The main menu with \optname{from DVD} + set}\label{fig:main-fromdvd} +\end{figure} + +Note the changes: all options about what to install have +disappeared, and the directories section now talks about +\dirname{TEXDIRW} or writable root. The symlinks option has also +disappeared. + +The installer will still create various directories and +configuration files, but won't copy \dirname{texmf}, +\dirname{texmf-dist} or \dirname{texmf-doc} to hard disk. + +Post-install configuration for Unix will be slightly more complicated, +because now the directory layout deviates from the default; see +section~\ref{sec:postinstall}. + +Due to time constraints, this option didn't make it into the \GUI{} +installer, but it is available both for Unix and for +Windows. Windows users have to start the installer from a command +prompt, see section~\ref{sec:cmdline}. + +Section \ref{sec:portable-unix} describes a more strictly portable +way to run \TL, which doesn't make or require changes in the +system's configuration, but doesn't allow any configuration either. + +\subsection{Command-line install options} +\label{sec:cmdline} + +Type +\begin{alltt} +> \Ucom{install-tl -help} +\end{alltt} +for a listing of command-line options. Either |-| or |--| can be used +to introduce option names. These are the more +interesting ones: + +\begin{ttdescription} +\item[-gui] If possible, use the \GUI{} installer. This requires the + Perl/Tk module (\url{http://tug.org/texlive/distro.html#perltk}); + if Perl/Tk is not available, installation continues in text mode. +\item[-no-gui] Force using the text mode installer, even under + Windows; you'll need this if you want a `from \DVD' installation, + since that is not available in \GUI{} mode. +\item[-lang {\sl LL}] Specify the installer interface + language as its standard two-letter code \textsl{LL}. Currently + supported languages: English (\texttt{en}, default), German + (\texttt{de}), French (\texttt{fr}), Dutch (\texttt{nl}), Polish + (\texttt{pl}), Slovenian (\texttt{sl}) and Vietnamese + (\texttt{vi}). The installer tries to determine the right language + itself but if it fails, or if the right language is not available, + then it uses English as a fallback. +\item[-profile {\sl profile}] The installer always writes a file + \filename{texlive.profile} to the \dirname{2008/tlpkg}- or + \dirname{tlpkg} subdirectory of your installation. This option tells + the installer to re-use such a profile file. Here's an excerpt: + \begin{fverbatim} +# texlive.profile written on Wed Jul 9 16:13:44 2008 UTC +# It will NOT be updated and reflects only the +# installation profile at installation time. +selected_scheme scheme-basic +TEXDIR /usr/local/texlive/2008 +TEXDIRW /usr/local/texlive/2008 +... +TEXMFSYSVAR /usr/local/texlive/2008/texmf-var +collection-basic 1 +... +option_symlinks 0 + \end{fverbatim} + Thus, using this option you can install in batch mode on + subsequent systems, reproducing the choices you made for the + original installation. +\item [-location {\sl url/path}] Specify a non-default source for + packages; see below. +\end{ttdescription} + +\subsubsection{The \optname{location} parameter} +\label{sec:location} + +The location value can be a url starting with \texttt{ftp:}, +\texttt{http:}, or \texttt{file:/} url, or a plain path. If the given +argument is on a local drive (either a path or a \texttt{file:/} url), +the installation type (compressed or live) is automatically determined: +if an \dirname{archive} subdirectory with \filename{.tar.lzma} files is +found then it will be used, even if uncompressed files are available as +well. + +When giving an \texttt{http:} or \texttt{ftp:} location, trailing +`\texttt{/}' characters and/or a trailing `\texttt{/tlpkg}' component +are ignored. For example, you could choose a particular \CTAN\ mirror +with something like: +\url{http://ctan.example.org/tex-archive/texlive/tlnet/2008}, +substituting of course a proper hostname and its particular top-level +\CTAN\ path (the list of \CTAN\ mirrors is maintained at +\url{http://ctan.org/mirrors}) for |ctan.example.org/tex-archive|. The +default is to pick a mirror automatically, using +\url{http://mirror.ctan.org}; in any case, the chosen host is used for +the entire download. + + +\subsection{Post-install actions} +\label{sec:postinstall} + +Some post-install may be required. + +\subsubsection{Windows} + +But on Windows, the installer takes care of everything. + +\subsubsection{If symlinks were created} + +If you elected to create symlinks in standard directories (mentioned in +section~\ref{sec:options}), then there is no need to edit environment +variables. + +\subsubsection{Environment variables for Unix} +\label{sec:env} + +The directory of the binaries for your platform must be added to +the search path. Each supported platform has its own subdirectory +under \dirname{TEXDIR/bin}. See figure~\ref{fig:bin-text} for the +list of subdirectories and corresponding platforms. + +You can also add the documentation man and Info directories to their +respective search paths, if you want the system tools to find them. + +For Bourne-compatible shells such as \prog{bash}, and using Intel x86 +GNU/Linux and a default directory setup as an example, the file to edit +might be \filename{$HOME/.profile} (or another file sourced by +\filename{.profile}, and the lines to add would look like this: + +\begin{sverbatim} +PATH=/usr/local/texlive/2008/bin/i386-linux:$PATH; export PATH +MANPATH=/usr/local/texlive/2008/texmf/doc/man:$MANPATH; export MANPATH +INFOPATH=/usr/local/texlive/2008/texmf/doc/info:$INFOPATH; export INFOPATH +\end{sverbatim} + +For csh or tcsh, the file to edit is typically \filename{$HOME/.cshrc}, and +the lines to add might look like: + +\begin{sverbatim} +setenv PATH /usr/local/texlive/2008/bin/i386-linux:$PATH +setenv MANPATH /usr/local/texlive/2008/texmf/doc/man:$MANPATH +setenv INFOPATH /usr/local/texlive/2008/texmf/doc/info:$INFOPATH +\end{sverbatim} + +Of course, you may well already have settings somewhere in your ``dot'' +files, and so then the \TL\ directories should simply be merged in as +appropriate. + +\subsubsection{Environment variables: global configuration} +\label{sec:envglobal} + +If you want to make these changes globally, or for a user newly added to +the system, then you are on your own; there is just too much variation +between systems in how and where these things are configured. + +Our two hints are: 1)~you may want to check for a file +\filename{/etc/manpath.config} and, if present, add lines such as + +\begin{sverbatim} +MANPATH_MAP /usr/local/texlive/2008/bin/i386-linux \ + /usr/local/texlive/2008/texmf/doc/man +\end{sverbatim} + +And 2)~check for a file \filename{/etc/environment} which may define the +search path and other default environment variables. + + +\subsubsection{When running from DVD} + +Normally, a \TL{} program consults a file \filename{texmf.cnf} for the +location of the various trees. It looks for this file in a series of +locations relative to its own location. However, this scheme breaks down +when a program is run from \DVD{}: the \DVD{} is read-only. Some of the +paths to be recorded in \filename{texmf.cnf} are only known at +installation time, so this file cannot be on the \DVD{} and must be +placed somewhere else. This makes it necessary to define an environment +\envname{TEXMFCNF} variable which tells \TL{} programs in what directory +to find this \filename{texmf.cnf}. It is also still necessary to modify +the \envname{PATH} environment variable, as described before. + +At the end of the installation, the installer should have printed a +message giving the value to which \envname{TEXMFCNF} should be set. In +case you missed it: this value is \dirname{$TEXMFSYSVAR/web2c}. For the +default, \dirname{/usr/local/texlive/2008/texmf-var/web2c}, you need the +lines +\begin{sverbatim} +TEXMFCNF=/usr/local/texlive/2008/texmf-var/web2c; export TEXMFCNF +\end{sverbatim} +or, for [t]csh: +\begin{sverbatim} +setenv TEXMFCNF /usr/local/texlive/2008/texmf-var/web2c +\end{sverbatim} + + +\subsubsection{\ConTeXt{} Mark IV} + +The `old' \ConTeXt{} should run out of the box. The new `Mark IV' +\ConTeXt{} will require manual setup; see +\url{http://wiki.contextgarden.net/Running_Mark_IV}. + + +\subsubsection{Integrating local and personal macros} +\label{sec:local-personal-macros} + +This is already mentioned implicitly in section~\ref{sec:texmftrees}: +\dirname{TEXMFLOCAL} (by default, +\dirname{/usr/local/texlive/texmf-local} or +\verb|C:\Program Files\texlive\texmf-local|) + +is intended for system-wide local fonts and macros; and +\dirname{TEXMFHOME} (by default, \dirname{$HOME/texmf} or +\verb|%USERPROFILE%\texmf|), is for personal fonts and macros. These +directories are intended to stick around from release to release, and +have their content seen automatically by a new \TL{} release. +Therefore, it is best to refrain from changing the definition of +\dirname{TEXMFLOCAL} to be too far away from the main \TL{} directory, +or you will need to manually change future releases. + +For both trees, files should be placed in their proper subdirectories; +see \url{http://tug.org/tds} or consult +\filename{texmf/web2c/texmf.cnf}. For instance, a \LaTeX{} class file or +package should be placed in \dirname{TEXMFLOCAL/tex/latex} or +\dirname{TEXMFHOME/tex/latex}, or a subdirectory thereof. + +\dirname{TEXMFLOCAL} requires an up-to-date filename database, or files +will not be found. You can update it with the command +\cmdname{mktexlsr} or use the `Reinit file database' button on the +configuration tab of \prog{tlmgr} in \GUI\ mode. + +\subsubsection{Integrating third-party fonts} + +This is unfortunately a very complicated and messy topic. Forget +about it unless you really know your way around blindfolded in a +\TeX{} installation. Don't forget to check first what you get for +free: see section~\ref{sec:tl-fonts}. + +A possible alternative is to use \XeTeX (see +section~\ref{sec:tex-extensions}), which lets you use operating system +fonts without any installation in \TeX. + + +\subsection{Testing the installation} +\label{sec:test-install} + +After installing \TL{} as best you can, you naturally want to test +it out, so you can start creating beautiful documents and\slash or fonts. + +This section gives some basic procedures for testing that the new system +is functional. We give Unix commands here; under \MacOSX{} and Windows, +you're more likely to run the tests through a graphical interface, but +the principles are the same. + +\begin{enumerate} + +\item Make sure that you can run the \cmdname{tex} program in the first +place: + +\begin{alltt} +> \Ucom{tex -{}-version} +TeX 3.1415926 (Web2C 7.5.7) +kpathsea version 3.5.7 +... +\end{alltt} +If this comes back with `command not found' instead of version and +copyright information, or with an older version, most likely you don't +have the correct \dirname{bin} subdirectory in your \envname{PATH}. See +the environment-setting information on \p.\pageref{sec:env}. + +\item Process a basic \LaTeX{} file: +\begin{alltt} +> \Ucom{latex sample2e.tex} +This is pdfeTeXk, Version 3.1415926... +... +Output written on sample2e.dvi (3 pages, 7484 bytes). +Transcript written on sample2e.log. +\end{alltt} +If this fails to find \filename{sample2e.tex} or other files, most +likely you have interference from old environment variables or +configuration files; we recommend unsetting all \TeX-related environment +variables for a start. (For a deep analysis, you can ask \TeX{} to +report on exactly what it is searching for, and finding; see ``Debugging +actions'' on page~\pageref{sec:debugging}.) + +\item Preview the result online: +\begin{alltt} +> \Ucom{xdvi sample2e.dvi} +\end{alltt} +(Under Windows, the analogous command is \cmdname{dviout}.) You should +see a new window with a nice document explaining some of the basics of +\LaTeX{}. (Well worth reading, by the way if you're new to the system.) +You do have to be running under X for \cmdname{xdvi} to work; if you're +not, or your \envname{DISPLAY} environment variable is set incorrectly, +you'll get an error \samp{Can't open display}. + +\item Create a \PS{} file for printing or display: +\begin{alltt} +> \Ucom{dvips sample2e.dvi -o sample2e.ps} +\end{alltt} + +\item Create a \acro{PDF} file instead of \dvi{}; this processes the +\filename{.tex} file and writes \acro{PDF} directly: +\begin{alltt} +> \Ucom{pdflatex sample2e.tex} +\end{alltt} + +\item Preview the \acro{PDF} file: +\begin{alltt} +> \Ucom{gv sample2e.pdf} +\textrm{or:} +> \Ucom{xpdf sample2e.pdf} +\end{alltt} +Unfortunately neither \cmdname{gv} nor \cmdname{xpdf} are currently +included in \TL{}, so you must install them separately. See +\url{http://www.gnu.org/software/gv} and +\url{http://www.foolabs.com/xpdf}, respectively. (There are plenty of +other \acro{PDF} viewers, too.) + +\item Standard test files you may find useful in addition to +\filename{sample2e.tex}: + +\begin{ttdescription} +\item [small2e.tex] A simpler document than \filename{sample2e}, to +reduce the input size if you're having troubles. +\item [testpage.tex] Test if your printer introduces any offsets. +\item [nfssfont.tex] For printing font tables and tests. +\item [testfont.tex] Also for font tables, but using plain \TeX{}. +\item [story.tex] The most canonical (plain) \TeX{} test file of all. +You must type \samp{\bs bye} to the \code{*} prompt after \samp{tex +story.tex}. +\end{ttdescription} + +\end{enumerate} + +If you are new to \TeX{}, or otherwise need help with actually writing +\TeX{} or \LaTeX{} documents, please visit +\url{http://tug.org/begin.html} for some introductory resources. + + +\section{Network installations} +\label{sec:netinstall} + +\TL{} has been designed to be shared between different users, and even +different systems on a network. With a standard directory layout, no +hard paths are configured: the locations for files needed by \TL{} +programs are defined relative to the places of those programs. You can +see this at work in the configuration file +\filename{$TEXMFMAIN/web2c/texmf.cnf}, which contains lines such as +\begin{sverbatim} +TEXMFMAIN = $SELFAUTOPARENT/texmf +... +TEXMFLOCAL = $SELFAUTOPARENT/../texmf-local +\end{sverbatim} +This means that other systems or other users merely need to add the +directory for \TL{} binaries for their platform to their search path. + +By the same token, you can also install \TL{} locally and then move +the entire hierarchy afterwards to a network location. + +Of course, Windows users have different expectations. The directory +\dirname{texmf-doc/source/texlive/texlive-common/w32client} contains a +sample script \filename{install-w32client} which creates settings and +menu shortcuts for using an existing \TL{} installation on a +\acro{LAN}. It is to be invoked through a batch file +\filename{install-w32client.bat} in the same directory. + +You can read more about \TL{} configuration and path searching in +section~\ref{sec:kpathsea}. + +\section{Maximally portable \protect\TL{} on DVD and USB} +\label{sec:portable-unix} + +The `running from \DVD{}' option described in +section~\ref{sec:fromdvd} is fine for your own system, but if you +are a guest on somebody else's system then you would probably like +something with minimal side effects. + +In the root of the \TL{} \DVD, or the \dirname{texlive} subdirectory of +the \TK{} \DVD, are a \filename{tl-portable} script (Unix) and a +\filename{tl-portable.bat} batchfile (Windows) which start up a +secondary shell\slash command prompt with environment settings suitable +for directly accessing the \TL{} on the \DVD. + +When it runs for the first time, some files will be generated in a +directory \dirname{~/.tlportable2008}, which will take a little time. +On subsequent runs, though, it will start almost instantaneously. + +The rest of the system will be unaware of \TL. If you want your editor +to be aware of this \TL, then you can start it from a second, parallel, +such \filename{tl-portable} session. + +You can also use \filename{tl-portable} to run \TL{} on a +\acro{USB} stick. In this case, copy all the top-level files and +the contents of the \dirname{bin}, \dirname{texmf}, +\dirname{texmf-dist}, and \dirname{tlpkg} directories (at least) to +the stick. This may take quite a while! If you are copying to a +\acro{FAT}32-formatted \acro{USB} stick, make sure to dereference +symbolic links (\code{cp -L}). A \dirname{texmf-local} directory on +the stick will also be found and used. + +Then run \filename{tl-portable} from the root of the stick, as above. +In this case, the script will notice that the stick is writable and use +it for generated files. You could burn the resulting contents of the +stick back to \DVD{} if that is more convenient to (for example) give to +others. + + +\section{\cmdname{tlmgr}: Managing your installation} +\label{sec:tlmgr} + +\begin{figure}[tb] +\tlpng{tlmgr-gui}{\linewidth} +\caption{\prog{tlmgr} in \GUI\ mode.

The programs \prog{updmap}, +\prog{fmtutil} and \prog{texconfig} are still included and will be +retained in the future, but \prog{tlmgr} is now the preferred interface. +Its capabilities include: + +\begin{itemize*} +\item listing schemes, collections and packages; +\item installing, updating, backing up, restoring and uninstalling + individual packages, optionally taking dependencies into account; +\item searching for packages; +\item listing and adding architectures; +\item changing installation options such as paper size and source + location (see section~\ref{sec:location}). +\end{itemize*} +\textit{Warning:} \prog{tlmgr} has not been designed for or tested +with installations which run from \DVD. + +\subsection{\cmdname{tlmgr} GUI mode} +\prog{tlmgr} can be started in \GUI{} mode with +\begin{alltt} +> \Ucom{tlmgr -gui} +\end{alltt} +or in Windows via the Start menu: \texttt{Start}, \texttt{Programs}, +\texttt{TeX Live 2008}, \texttt{TeX Live Manager}.

This +was only possible by dropping support for older Windows versions, so +\TL\ can now be installed only on Windows 2000 and later. + + +\subsection{Windows-specific features} +\label{sec:winfeatures} + +Under Windows, the installer does some extra things: +\begin{description} +\item[Menus and shortcuts.] A new `\TL{}' submenu of the + Start menu is installed, which contains entries for some \GUI{} programs + (\prog{tlmgr}, \prog{texdoctk}, the PS\_View PostScript previewer) + and some documentation. PS\_View also gets a shortcut on the + desktop as a drag-and-drop target for PostScript files. +\item[Automatic setting of environment variables.] No manual + configuration steps are required. +\item[Uninstaller.] The installer creates an entry under `Add/Remove + Programs' for \TL. The uninstall tab of\prog{tlmgr} refers to + this. +\end{description} + +\subsection{Additional included software} + +\begin{figure}[tb] +\tlpng{psview}{.6\linewidth} +\caption{PS\_View: very high magnifications available!}\label{fig:psview} +\end{figure} + +To be complete, a \TL installation needs support packages that are not +commonly found on a Windows machine. \TL{} provides the missing +pieces: +\begin{description} +\item[Perl and Ghostscript.] Because of the importance of Perl and + Ghostscript, \TL{} includes `hidden' copies of these + programs. \TL{} programs that need them know where to find them, + but they don't betray their presence through environment variables + or registry settings. They aren't full-scale distributions, and + shouldn't interfere with any system installations of Perl or + Ghostscript. +\item[Command-line tools.] A number of Windows ports of common Unix + command-line programs are installed along with the usual \TL{} + binaries. These include \cmdname{gzip}, \cmdname{chktex}, + \cmdname{jpeg2ps}, \cmdname{unzip}, \cmdname{wget} and the + command-line utilities from the \cmdname{xpdf} suite. (The + \cmdname{xpdf} viewer itself is not available for Windows, but the + Sumatra \acro{PDF} viewer is based on it: + \url{http://blog.kowalczyk.info/software/sumatrapdf}.) +\item[\texttt{fc-cache}] helps \XeTeX{} to handle fonts more + efficiently. +\item[PS\_View.] Also installed is PS\_View, a new PostScript viewer + with a free license; see figure~\ref{fig:psview}. +\end{description} +\begin{description} +\item[The \texttt{support} directory,] already mentioned in + section~\ref{sec:tld}. This directory contains various programs + which can be useful in connection with \TeX, in particular a + number of \TeX-aware editors and \TeX{} frontends. The software in + this directory isn't covered by the installer. This directory also + contains the \cmdname{dviout} \dvi{} previewer; see the next section. +\end{description} + +\subsection{The Dviout previewer} + +This \TL{} release unfortunately doesn't offer a preinstalled \dvi{} +previewer for Windows. However, you can install \prog{dviout} by +Toshio Oshima from the \path{support/dviout/} directory, which +contains also a short \filename{README} describing how to install +and configure \prog{dviout} for \TL. Please read this carefully +before installation. + +At first, when you preview files with \cmdname{dviout}, it will create fonts, +because screen fonts were not installed. After a while, you will have created +most of the fonts you use, and you will rarely see the font-creation window. +More information can be found in the (very good) on-line help. + +\subsection{Links for additional downloadable software} + +Urls for some other tools you may consider installing: +\begin{description} +\item[Ghostscript] \url{http://www.cs.wisc.edu/~ghost/} +\item[Perl] \url{http://www.perl.org/} with + supplementary packages from \acro{CPAN}, \url{http://www.cpan.org/} +\item[ImageMagick] \url{http://www.imagemagick.com}, for graphics + processing and conversion +\item[NetPBM] \url{http://netpbm.sourceforge.net/}, also for graphics. + +\item[\TeX-oriented editors] There is a wide choice, and it is a matter of the + user's taste. Here is a selection, in no particular order: + \begin{itemize*} + \item \cmdname{GNU Emacs} is available natively under Windows, see + \url{http://www.gnu.org/software/emacs/windows/ntemacs.html}. + \item \cmdname{Emacs} with Auc\TeX\ for Windows is available in \TL's + \path{support} directory; its home page is + \url{http://www.gnu.org/software/auctex}. + \item \cmdname{WinShell} is available in \TL's \path|support| + directory; its home page is \url{http://www.winshell.de}. + \item \cmdname{WinEdt} is shareware available from + \url{http://www.winedt.com}. + \item \cmdname{Vim} is free software, available from + \url{http://www.vim.org}. + \item TeXnicCenter is free software, available from + \url{http://www.toolscenter.org} and in the pro\TeX{}t distribution. + \item \cmdname{LEd} is available from \url{http://www.ctan.org/support/LEd}. + \item \cmdname{SciTE} is available from + \url{http://www.scintilla.org/SciTE.html}. + \end{itemize*} +\end{description} + + +\subsection{User Profile is Home} +\label{sec:winhome} + +The Windows counterpart of a Unix home directory is the +\verb|%USERPROFILE%| directory. Under Windows XP and Windows 2000, this +is usually \verb|C:\Documents and Settings\<username>|, and under +Windows Vista \verb|C:\Users\<username>|. In the +\filename{texmf.cnf} file, and \KPS{} in general, \verb|~| will expand +appropriately on both Windows and Unix. + + +\subsection{The Windows registry} +\label{sec:registry} + +Windows stores nearly all configuration data in its registry. The +registry contains a set of hierarchically organized keys, with several +root keys. The most important ones for installation programs are +\path{HKEY_CURRENT_USER} and \path{HKEY_LOCAL_MACHINE}, \path{HKCU} and +\path{HKLM} in short. The \path{HKCU} part of the registry is in the +user's home directory (see section~\ref{sec:winhome}). \path{HKLM} is +normally in a subdirectory of the Windows directory. + +In some cases, system information could be obtained from environment +variables but for other information, for example the location of +shortcuts, it is necessary to consult the registry. Setting environment +variables permanently also requires registry access. + + +\subsection{Windows permissions} +\label{sec:winpermissions} + +In later versions of Windows, a distinction is made between regular +users and administrators, where only the latter have free access to the +entire operating system. In practice, though, you could better describe +these classes of users as unprivileged users and normal users: being an +administrator is the rule, not the exception. Nevertheless, we have made +an effort to make \TL{} installable without administrative privileges. + +If the user is an administrator, shortcuts are created for all users, +and the system environment is modified. Otherwise, shortcuts and menu +entries are created for the current user, and the user environment is +modified. Use the \optname{non-admin} option to \prog{install-tl} if +you prefer per-user settings even as an administrator. + +Regardless of administrator status, the default root of \TL{} proposed +by the installer is always under \verb|%PROGRAMFILES%|. The installer +always tests whether the root is writable for the current user. + +A problem may arise if the user is not an administrator and \TeX{} +already exists in the search path. Since the effective path consists of +the system path followed by the user path, the new \TL{} will never get +precedence. As a workaround, in this case the installer creates +shortcuts to the command-prompt in which the new \TL{} binary directory +is prepended to the local searchpath. The new \TL{} will be usable when +run in a command-line session started from such a shortcut. + + +\section{A user's guide to Web2C} + +\Webc{} is an integrated collection of \TeX-related programs: \TeX{} +itself, \MF{}, \MP, \BibTeX{}, etc. It is the heart of \TL{}. The home +page for \Webc{}, with the current manual and more, is +\url{http://tug.org/web2c}. + +A bit of history: The original implementation was by Tomas Rokicki who, +in 1987, developed a first \TeX{}-to-C system based on change files +under Unix, which were primarily the original work of Howard Trickey and +Pavel Curtis. Tim Morgan became the maintainer of the system, and +during this period the name changed to Web-to-C\@. In 1990, Karl Berry +took over the work, assisted by dozens of additional contributors, and +in 1997 he handed the baton to Olaf Weber, who returned it to Karl in +2006. + +The \Webc{} system runs on Unix, 32-bit Windows systems, \MacOSX{}, and +other operating systems. It uses Knuth's original sources for \TeX{} and +other basic programs written in the \web{} literate programming system +and translates them into C source code. The core \TeX{} programs +handled in this way are: + +\begin{cmddescription} +\item[bibtex] Maintaining bibliographies. +\item[dmp] \cmdname{troff} to MPX (\MP{} pictures). +\item[dvicopy] Expands virtual font references in \dvi{} files. +\item[dvitomp] \dvi{} to MPX (MetaPost pictures). +\item[dvitype] \dvi{} to human-readable text. +\item[gftodvi] Generic font proofsheets. +\item[gftopk] Generic to packed fonts. +\item[gftype] GF to human-readable text. +\item[makempx] \MP{} label typesetting. +\item[mf] Creating typeface families. +\item[mft] Prettyprinting \MF{} source. +\item[mpost] Creating technical diagrams. +\item[mpto] MetaPost label extraction. +\item[newer] Compare modification times. +\item[patgen] Creating hyphenation patterns. +\item[pktogf] Packed to generic fonts. +\item[pktype] PK to human-readable text. +\item[pltotf] Plain text property list to TFM. +\item[pooltype] Display \web{} pool files. +\item[tangle] \web{} to Pascal. +\item[tex] Typesetting. +\item[tftopl] TFM to plain text property list. +\item[vftovp] Virtual font to virtual property list. +\item[vptovf] Virtual property list to virtual font. +\item[weave] \web{} to \TeX. +\end{cmddescription} + +\noindent The precise functions and syntax of these programs are +described in the documentation of the individual packages and of \Webc{} +itself. However, knowing a few principles governing the whole family of +programs will help you take advantage of your \Webc{} installation. + +All programs honor these standard \GNU options: +\begin{ttdescription} +\item[-{}-help] print basic usage summary. +\item[-{}-verbose] print detailed progress report. +\item[-{}-version] print version information, then exit. +\end{ttdescription} + +For locating files the \Webc{} programs use the path searching library +\KPS{} (\url{http://tug.org/kpathsea}). This library uses a combination +of environment variables and a configuration files to optimize searching +the (huge) collection of \TeX{} files. \Webc{} can look at many +directory trees simultaneously, which is useful in maintaining \TeX's +standard distribution and local and personal extensions in distinct +trees. To speed up file searches, the root of each tree has a file +\file{ls-R}, containing an entry showing the name and relative pathname +for all files under that root. + + +\subsection{Kpathsea path searching} +\label{sec:kpathsea} + +Let us first describe the generic path searching mechanism of the \KPS{} +library. + +We call a \emph{search path} a colon- or semicolon\hyph sepa\-rated list +of \emph{path elements}, which are basically directory names. A +search path can come from (a combination of) many sources. To look up +a file \samp{my-file} along a path \samp{.:/dir}, \KPS{} checks each +element of the path in turn: first \file{./my-file}, then +\file{/dir/my-file}, returning the first match (or possibly all +matches). + +In order to adapt optimally to all operating systems' conventions, on +non-Unix systems \KPS{} can use filename separators different from +colon (\samp{:}) and slash (\samp{/}). + +To check a particular path element \var{p}, \KPS{} first checks if a +prebuilt database (see ``Filename data\-base'' on +page~\pageref{sec:filename-database}) applies to \var{p}, i.e., if the +database is in a directory that is a prefix of \var{p}. If so, the path +specification is matched against the contents of the database. + +If the database does not exist, or does not apply to this path +element, or contains no matches, the filesystem is searched (if this +was not forbidden by a specification starting with \samp{!!}\ and if +the file being searched for must exist). \KPS{} constructs the list +of directories that correspond to this path element, and then checks +in each for the file being sought. + +The ``file must exist'' condition comes into play with \samp{.vf} files and +input files read by \TeX's \cs{openin} command. Such files may not +exist (e.g., \file{cmr10.vf}), and so it would be wrong to search the +disk for them. Therefore, if you fail to update \file{ls-R} when you +install a new \samp{.vf} file, it will never be found. +Each path element is checked in turn: first the database, then the +disk. If a match is found, the search stops and the result is +returned. + +Although the simplest and most common path element is a directory +name, \KPS{} supports additional features in search paths: layered +default values, environment variable names, config file values, users' +home directories, and recursive subdirectory searching. Thus, we say +that \KPS{} \emph{expands} a path element, meaning it transforms all +the specifications into basic directory name or names. This is +described in the following sections in the same order as it takes +place. + +Note that if the filename being searched for is absolute or explicitly +relative, i.e., starts with \samp{/} or \samp{./} or \samp{../}, +\KPS{} simply checks if that file exists. + +\ifSingleColumn +\else +\begin{figure*} +\verbatiminput{examples/ex5.tex} +\setlength{\abovecaptionskip}{0pt} + \caption{An illustrative configuration file sample} + \label{fig:config-sample} +\end{figure*} +\fi + +\subsubsection{Path sources} +\label{sec:path-sources} + +A search path can come from many sources. In the order in which +\KPS{} uses them: + +\begin{enumerate} +\item + A user-set environment variable, for instance, \envname{TEXINPUTS}\@. + Environment variables with a period and a program name appended + override; e.g., if \samp{latex} is the name of the program being run, + then \envname{TEXINPUTS.latex} will override \envname{TEXINPUTS}. +\item + A program-specific configuration file, for exam\-ple, a line + \samp{S /a:/b} in \cmdname{dvips}'s \file{config.ps}. +\item A \KPS{} configuration file \file{texmf.cnf}, containing a line like + \samp{TEXINPUTS=/c:/d} (see below). +\item The compile-time default. +\end{enumerate} +\noindent You can see each of these values for a given search path by +using the debugging options (see ``Debugging actions'' on +page~\pageref{sec:debugging}). + +\subsubsection{Config files} + +\begingroup\tolerance=3500 +\KPS{} reads \emph{runtime configuration files} named \file{texmf.cnf} +for search path and other definitions. The search path used to look +for these files is named \envname{TEXMFCNF} (by default such a file lives +in the \file{texmf/web2c} subdirectory). \emph{All} +\file{texmf.cnf} files in the search path will be read and definitions +in earlier files override those in later files. Thus, with a search +path of \verb|.:$TEXMF|, values from \file{./texmf.cnf} override those +from \verb|$TEXMF/texmf.cnf|. +\endgroup + +\begin{itemize} +\item + Comments start with \code{\%} and continue to the end of the line. +\item + Blank lines are ignored. +\item + A \bs{} at the end of a line acts as a continuation character, + i.e., the next line is appended. Whitespace at the beginning of + continuation lines is not ignored. +\item + Each remaining line has the form: +\begin{alltt} + \var{variable}[.\var{progname}] [=] \var{value} +\end{alltt}% + where the \samp{=} and surrounding whitespace are optional. +\item + The \ttvar{variable} name may contain any character other + than whitespace, \samp{=}, or \samp{.}, but sticking to + \samp{A-Za-z\_} is safest. +\item + If \samp{.\var{progname}} is present, the definition only + applies if the program that is running is named + \texttt{\var{progname}} or \texttt{\var{progname}.exe}. This allows + different flavors of \TeX{} to have different search paths, for + example. +\item \var{value} may contain any characters except + \code{\%} and \samp{@}. The + \code{\$\var{var}.\var{prog}} feature is not available on the + right-hand side; instead, you must use an additional variable. A + \samp{;}\ in \var{value} is translated to \samp{:}\ if + running under Unix; this is useful to be able to have a single + \file{texmf.cnf} for Unix, \acro{MS-DOS} and Windows systems. +\item + All definitions are read before anything is expanded, so + variables can be referenced before they are defined. +\end{itemize} +A configuration file fragment illustrating most of these points is +\ifSingleColumn +shown below: + +\verbatiminput{examples/ex5.tex} +\else +shown in Figure~\ref{fig:config-sample}. +\fi + +\subsubsection{Path expansion} +\label{sec:path-expansion} + + +\KPS{} recognizes certain special characters and constructions in +search paths, similar to those available in Unix shells. As a +general example, the complex path, +\verb+~$USER/{foo,bar}//baz+, expands to all subdirectories under +directories \file{foo} and \file{bar} in \texttt{\$USER}'s home +directory that contain a directory or file \file{baz}. These +expansions are explained in the sections below. +%$ +\subsubsection{Default expansion} +\label{sec:default-expansion} + +\tolerance=2500 +If the highest-priority search path (see ``Path sources'' on +page~\pageref{sec:path-sources}) contains an \emph{extra colon} (i.e., +leading, trailing, or doubled), \KPS{} inserts at that point the +next-highest-prio\-rity search path that is defined. If that inserted +path has an extra colon, the same happens with the next highest. For +example, given an environment variable setting + +\tolerance=1500 + +\begin{alltt} +> \Ucom{setenv TEXINPUTS /home/karl:} +\end{alltt} +and a \code{TEXINPUTS} value from \file{texmf.cnf} of + +\begin{alltt} + .:\$TEXMF//tex +\end{alltt} +then the final value used for searching will be: + +\begin{alltt} + /home/karl:.:\$TEXMF//tex +\end{alltt} + +Since it would be useless to insert the default value in more than one +place, \KPS{} changes only one extra \samp{:}\ and leaves any others in +place. It checks first for a leading \samp{:}, then a trailing +\samp{:}, then a doubled \samp{:}. + +\subsubsection{Brace expansion} + +A useful feature is brace expansion, which means that, for instance, +\verb+v{a,b}w+ expands to \verb+vaw:vbw+. Nesting is allowed. +This is used to implement multiple \TeX{} hierarchies, by +assigning a brace list to \code{\$TEXMF}. +For example, in \file{texmf.cnf}, the following definition +(appproximately; there are actually even more trees) is made: +\begin{verbatim} + TEXMF = {$TEXMFHOME,$TEXMFLOCAL,!!$TEXMFVAR,!!$TEXMFMAIN} +\end{verbatim} +Using this you can then write something like +\begin{verbatim} + TEXINPUTS = .;$TEXMF/tex// +\end{verbatim} +%$ +which means that, after looking in the current directory, the +\code{\$TEXMFHOME/tex}, \code{\$TEXMFLOCAL/tex}, \code{\$TEXMFVAR/tex} +and \code{\$TEXMFMAIN/tex} trees \emph{only}) will be searched (the +last two use using \file{ls-R} data base files). It is a convenient +way for running two parallel \TeX{} structures, one ``frozen'' (on a +\CD, for instance) and the other being continuously updated with new +versions as they become available. By using the \code{\$TEXMF} +variable in all definitions, one is sure to always search the +up-to-date tree first. + +\subsubsection{Subdirectory expansion} +\label{sec:subdirectory-expansion} + +Two or more consecutive slashes in a path element following a directory +\var{d} is replaced by all subdirectories of \var{d}: first those +subdirectories directly under \var{d}, then the subsubdirectories under +those, and so on. At each level, the order in which the directories are +searched is \emph{unspecified}. + +If you specify any filename components after the \samp{//}, only +subdirectories with matching components are included. For example, +\samp{/a//b} expands into directories \file{/a/1/b}, \file{/a/2/b}, +\file{/a/1/1/b}, and so on, but not \file{/a/b/c} or \file{/a/1}. + +Multiple \samp{//} constructs in a path are possible, but +\samp{//} at the beginning of a path is ignored. + +\subsubsection{List of special characters and their meaning: a summary} + +The following list summarizes the special characters in \KPS{} +configuration files. + +% need a wider space for the item labels here. +\newcommand{\CODE}[1]{\makebox[3em][l]{\code{#1}}} +\begin{ttdescription} +\item[\CODE{:}] Separator in path specification; at the beginning or + the end of a path it substitutes the default path expansion.\par +\item[\CODE{;}] Separator on non-Unix systems (acts like \code{:}). +\item[\CODE{\$}] Variable expansion. +\item[\CODE{\string~}] Represents the user's home directory. +\item[\CODE{\char`\{...\char`\}}] Brace expansion. +\item[\CODE{//}] Subdirectory expansion (can occur anywhere in + a path, except at its beginning). +\item[\CODE{\%}] Start of comment. +\item[\CODE{\bs}] Continuation character (allows multi-line entries). +\item[\CODE{!!}] Search \emph{only} database to locate file, \emph{do + not} search the disk. +\end{ttdescription} + + +\subsection{Filename databases} +\label{sec:filename-database} + +\KPS{} goes to some lengths to minimize disk accesses for searches. +Nevertheless, at installations with enough directories, searching each +possible directory for a given file can take an excessively long time +(this is especially true if many hundreds of font directories have to +be traversed.) Therefore, \KPS{} can use an externally-built plain text +``database'' file named \file{ls-R} that maps files to directories, +thus avoiding the need to exhaustively search the disk. + +A second database file \file{aliases} allows you to give additional +names to the files listed in \file{ls-R}. This can be helpful to +confirm to \acro{DOS} 8.3 filename conventions in source files. + +\subsubsection{The filename database} +\label{sec:ls-R} + +As explained above, the name of the main filename database must be +\file{ls-R}. You can put one at the root of each \TeX{} hierarchy in +your installation that you wish to be searched (\code{\$TEXMF} by +default); most sites have only one hierarchy. \KPS{} looks for +\file{ls-R} files along the \code{TEXMFDBS} path. + +The recommended way to create and maintain \samp{ls-R} is to run the +\code{mktexlsr} script included with the distribution. It is invoked +by the various \samp{mktex}\dots\ scripts. In principle, this script +just runs the command +\begin{alltt} +cd \var{/your/texmf/root} && \path|\|ls -1LAR ./ >ls-R +\end{alltt} +presuming your system's \code{ls} produces the right output format +(\GNU \code{ls} is all right). To ensure that the database is +always up-to-date, it is easiest to rebuild it regularly via +\code{cron}, so that it is automatically updated when the installed +files change, such as after installing or updating a \LaTeX{} package. + +If a file is not found in the database, by default \KPS{} goes ahead +and searches the disk. If a particular path element begins with +\samp{!!}, however, \emph{only} the database will be searched for that +element, never the disk. + + +\subsubsection{kpsewhich: Standalone path searching} +\label{sec:invoking-kpsewhich} + +The \texttt{kpsewhich} program exercises path searching independent of any +particular application. This can be useful as a sort of \code{find} +program to locate files in \TeX{} hierarchies (this is used heavily in +the distributed \samp{mktex}\dots\ scripts). + +\begin{alltt} +> \Ucom{kpsewhich \var{option}\dots{} \var{filename}\dots{}} +\end{alltt} +The options specified in \ttvar{option} start with either \samp{-} +or \samp{-{}-}, and any unambiguous abbreviation is accepted. + +\KPS{} looks up each non-option argument on the command line as a +filename, and returns the first file found. There is no option to +return all the files with a particular name (you can run the Unix +\samp{find} utility for that). + +The most common options are described next. + +\begin{ttdescription} +\item[\texttt{-{}-dpi=\var{num}}]\mbox{} + Set the resolution to \ttvar{num}; this only affects \samp{gf} + and \samp{pk} lookups. \samp{-D} is a synonym, for compatibility + with \cmdname{dvips}. Default is 600. + +\item[\texttt{-{}-format=\var{name}}]\mbox{}\\ + Set the format for lookup to \ttvar{name}. By default, the + format is guessed from the filename. For formats which do not have + an associated unambiguous suffix, such as \MP{} support files and + \cmdname{dvips} configuration files, you have to specify the name as + known to \KPS{}, such as \texttt{tex} or \texttt{enc files}. Run + \texttt{kpsewhich -{}-help} for a list. + +\item[\texttt{-{}-mode=\var{string}}]\mbox{}\\ + Set the mode name to \ttvar{string}; this only affects \samp{gf} + and \samp{pk} lookups. No default: any mode will be found. +\item[\texttt{-{}-must-exist}]\mbox{}\\ + Do everything possible to find the files, notably including + searching the disk. By default, only the \file{ls-R} database is + checked, in the interest of efficiency. +\item[\texttt{-{}-path=\var{string}}]\mbox{}\\ + Search along the path \ttvar{string} (colon-separated as usual), + instead of guessing the search path from the filename. \samp{//} and + all the usual expansions are supported. The options \samp{-{}-path} + and \samp{-{}-format} are mutually exclusive. +\item[\texttt{-{}-progname=\var{name}}]\mbox{}\\ + Set the program name to \texttt{\var{name}}. + This can affect the search paths via the \texttt{.\var{progname}} + feature. + The default is \cmdname{kpsewhich}. +\item[\texttt{-{}-show-path=\var{name}}]\mbox{}\\ + shows the path used for file lookups of file type \texttt{\var{name}}. + Either a filename extension (\code{.pk}, \code{.vf}, etc.) or a + name can be used, just as with \samp{-{}-format} option. +\item[\texttt{-{}-debug=\var{num}}]\mbox{}\\ + sets the debugging options to \texttt{\var{num}}. +\end{ttdescription} + + +\subsubsection{Examples of use} +\label{sec:examples-of-use} + +Let us now have a look at \KPS{} in action. Here's a straightforward search: + +\begin{alltt} +> \Ucom{kpsewhich article.cls} + /usr/local/texmf-dist/tex/latex/base/article.cls +\end{alltt} +We are looking for the file \file{article.cls}. Since the \samp{.cls} +suffix is unambiguous we do not need to specify that we want to look for a +file of type \optname{tex} (\TeX{} source file directories). We find it in +the subdirectory \file{tex/latex/base} below the \samp{texmf-dist} \TL\ +directory. Similarly, all of the following are found without problems +thanks to their unambiguous suffix. +\begin{alltt} +> \Ucom{kpsewhich array.sty} + /usr/local/texmf-dist/tex/latex/tools/array.sty +> \Ucom{kpsewhich latin1.def} + /usr/local/texmf-dist/tex/latex/base/latin1.def +> \Ucom{kpsewhich size10.clo} + /usr/local/texmf-dist/tex/latex/base/size10.clo +> \Ucom{kpsewhich small2e.tex} + /usr/local/texmf-dist/tex/latex/base/small2e.tex +> \Ucom{kpsewhich tugboat.bib} + /usr/local/texmf-dist/bibtex/bib/beebe/tugboat.bib +\end{alltt} + +By the way, that last is a \BibTeX{} bibliography database for \textsl{TUGBoat} articles. + +\begin{alltt} +> \Ucom{kpsewhich cmr10.pk} +\end{alltt} +Font bitmap glyph files of type \file{.pk} are used by display +programs like \cmdname{dvips} and \cmdname{xdvi}. Nothing is returned in +this case since there are no pre-generated Computer Modern \samp{.pk} +files in \TL{}\Dash the Type~1 variants are used by default. +\begin{alltt} +> \Ucom{kpsewhich wsuipa10.pk} +\ifSingleColumn /usr/local/texmf-var/fonts/pk/ljfour/public/wsuipa/wsuipa10.600pk +\else /usr/local/texmf-var/fonts/pk/ljfour/public/ +... wsuipa/wsuipa10.600pk +\fi\end{alltt} +For these fonts (a phonetic alphabet from the University of Washington) +we had to generate \samp{.pk} files, and since the default \MF{} mode on +our installation is \texttt{ljfour} with a base resolution of 600\dpi{} +(dots per inch), this instantiation is returned. +\begin{alltt} +> \Ucom{kpsewhich -dpi=300 wsuipa10.pk} +\end{alltt} +In this case, when specifying that we are interested in a resolution +of 300\dpi{} (\texttt{-dpi=300}) we see that no such font is available on +the system. A program like \cmdname{dvips} or \cmdname{xdvi} would +go off and actually build the required \texttt{.pk} files +using the script \cmdname{mktexpk}. + +Next we turn our attention to \cmdname{dvips}'s header and configuration +files. We first look at one of the commonly used files, the general +prologue \file{tex.pro} for \TeX{} support, before turning our attention +to the generic configuration file (\file{config.ps}) and the \PS{} font +map \file{psfonts.map}\Dash as of 2004, map and encoding files have +their own search paths and new location in \dirname{texmf} trees. As +the \samp{.ps} suffix is ambiguous we have to specify explicitly which +type we are considering (\optname{dvips config}) for the file +\texttt{config.ps}. +\begin{alltt} +> \Ucom{kpsewhich tex.pro} + /usr/local/texmf/dvips/base/tex.pro +> \Ucom{kpsewhich --format="dvips config" config.ps} + /usr/local/texmf/dvips/config/config.ps +> \Ucom{kpsewhich psfonts.map} + /usr/local/texmf/fonts/map/dvips/updmap/psfonts.map +\end{alltt} + +We now take a closer look at the \acro{URW} Times \PS{} support +files. The prefix for these in the standard font naming scheme is +\samp{utm}. The first file we look at is the configuration file, +which contains the name of the map file: +\begin{alltt} +> \Ucom{kpsewhich --format="dvips config" config.utm} + /usr/local/texmf-dist/dvips/psnfss/config.utm +\end{alltt} +The contents of that file is +\begin{alltt} + p +utm.map +\end{alltt} +which points to the file \file{utm.map}, which we want to +locate next. +\begin{alltt} +> \Ucom{kpsewhich utm.map} + /usr/local/texmf-dist/fonts/map/dvips/times/utm.map +\end{alltt} +This map file defines the file names of the Type~1 \PS{} fonts in +the URW collection. Its contents look like (we only show part of the +lines): +\begin{alltt} +utmb8r NimbusRomNo9L-Medi ... <utmb8a.pfb +utmbi8r NimbusRomNo9L-MediItal... <utmbi8a.pfb +utmr8r NimbusRomNo9L-Regu ... <utmr8a.pfb +utmri8r NimbusRomNo9L-ReguItal... <utmri8a.pfb +utmbo8r NimbusRomNo9L-Medi ... <utmb8a.pfb +utmro8r NimbusRomNo9L-Regu ... <utmr8a.pfb +\end{alltt} +Let us, for instance, take the Times Roman instance +\file{utmr8a.pfb} and find its position in the \file{texmf} directory +tree with a search for Type~1 font files: +\begin{alltt} +> \Ucom{kpsewhich utmr8a.pfb} +\ifSingleColumn /usr/local/texmf-dist/fonts/type1/urw/times/utmr8a.pfb +\else /usr/local/texmf-dist/fonts/type1/ +... urw/utm/utmr8a.pfb +\fi\end{alltt} + +It should be evident from these examples how you can easily locate the +whereabouts of a given file. This is especially important if you suspect +that the wrong version of a file is picked up somehow, since +\cmdname{kpsewhich} will show you the first file encountered. + +\subsubsection{Debugging actions} +\label{sec:debugging} + +Sometimes it is necessary to investigate how a program resolves file +references. To make this practical, \KPS{} offers various levels of +debugging output: + +\begin{ttdescription} +\item[\texttt{\ 1}] \texttt{stat} calls (disk lookups). When running + with an up-to-date \file{ls-R} database this should almost give no + output. +\item[\texttt{\ 2}] References to hash tables (such as \file{ls-R} + databases, map files, configuration files). +\item[\texttt{\ 4}] File open and close operations. +\item[\texttt{\ 8}] General path information for file types + searched by \KPS. This is useful to find out where a particular + path for the file was defined. +\item[\texttt{16}] Directory list for each path element (only relevant + for searches on disk). +\item[\texttt{32}] File searches. +\item[\texttt{64}] Variable values. +\end{ttdescription} +A value of \texttt{-1} will set all the above options; in practice, +this is usually the most convenient. + +Similarly, with the \cmdname{dvips} program, by setting a combination of +debug switches, one can follow in detail where files are being picked up +from. Alternatively, when a file is not found, the debug trace shows in +which directories the program looks for the given file, so that one can +get an indication what the problem~is. + +Generally speaking, as most programs call the \KPS{} library +internally, one can select a debug option by using the +\envname{KPATHSEA\_DEBUG} environment variable, and setting it to (a +combination of) values as described in the above list. + +(Note for Windows users: it is not easy to redirect +all messages to a file in this system. For diagnostic purposes +you can temporarily \texttt{SET KPATHSEA\_DEBUG\_OUTPUT=err.log}). + +Let us consider, as an example, a small \LaTeX{} source file, +\file{hello-world.tex}, which contains the following input. +\begin{verbatim} + \documentclass{article} + \begin{document} + Hello World! + \end{document} +\end{verbatim} +This little file only uses the font \file{cmr10}, so let us look at +how \cmdname{dvips} prepares the \PS{} file (we want to use the Type~1 +version of the Computer Modern fonts, hence the option \texttt{-Pcms}). +\begin{alltt} +> \Ucom{dvips -d4100 hello-world -Pcms -o} +\end{alltt} +In this case we have combined \cmdname{dvips}'s debug class 4 (font +paths) with \KPS's path element expansion (see \cmdname{dvips} Reference +Manual, \OnCD{texmf/doc/dvips/dvips.pdf}). +The output (slightly rearranged) appears in +Figure~\ref{fig:dvipsdbga}. +\begin{figure*}[tp] +\centering +\input{examples/ex6a.tex} +\caption{Finding configuration files}\label{fig:dvipsdbga} + +\bigskip + +\input{examples/ex6b.tex} +\caption{Finding the prolog file}\label{fig:dvipsdbgb} + +\bigskip + +\input{examples/ex6c.tex} +\caption{Finding the font file}\label{fig:dvipsdbgc} +\end{figure*} + +\cmdname{dvips} starts by locating its working files. First, +\file{texmf.cnf} is found, which gives the definitions of the search +paths for the other files, then the file database \file{ls-R} (to +optimize file searching) and the file \file{aliases}, which makes it +possible to declare several names (e.g., a short \acro{DOS}-like 8.3 and +a more natural longer version) for the same file. Then \cmdname{dvips} +goes on to find the generic configuration file \file{config.ps} +before looking for the customization file \file{.dvipsrc} (which, in +this case is \emph{not found}). Finally, \cmdname{dvips} locates the +config file for the Computer Modern \PS{} fonts \file{config.cms} +(this was initiated with the \texttt{-Pcms} option on the \cmdname{dvips} +command). This file contains the list of the map files which +define the relation between the \TeX{}, \PS{} and file system +names of the fonts. +\begin{alltt} +> \Ucom{more /usr/local/texmf/dvips/cms/config.cms} + p +ams.map + p +cms.map + p +cmbkm.map + p +amsbkm.map +\end{alltt} +\cmdname{dvips} thus goes on to find all these files, plus the generic +map file \file{psfonts.map}, which is always loaded (it contains +declarations for commonly used \PS{} fonts; see the last part of +Section \ref{sec:examples-of-use} for more details about \PS{} map +file handling). + +At this point \cmdname{dvips} identifies itself to the user: +\begin{alltt} +This is dvips(k) 5.92b Copyright 2002 Radical Eye Software (www.radicaleye.com) +\end{alltt} +\ifSingleColumn +Then it goes on to look for the prolog file \file{texc.pro}: +\begin{alltt}\small +kdebug:start search(file=texc.pro, must\_exist=0, find\_all=0, + path=.:~/tex/dvips//:!!/usr/local/texmf/dvips//: + ~/tex/fonts/type1//:!!/usr/local/texmf/fonts/type1//). +kdebug:search(texc.pro) => /usr/local/texmf/dvips/base/texc.pro +\end{alltt} +\else +Then it goes on to look for the prolog file \file{texc.pro} (see +Figure~\ref{fig:dvipsdbgb}). +\fi + +After having found the file in question, \cmdname{dvips} outputs +the date and time, and informs us that it will generate the +file \file{hello-world.ps}, then that it needs the font file +\file{cmr10}, and that the latter is declared as ``resident'' (no +bitmaps needed): +\begin{alltt}\small +TeX output 1998.02.26:1204' -> hello-world.ps +Defining font () cmr10 at 10.0pt +Font cmr10 <CMR10> is resident. +\end{alltt} +Now the search is on for the file \file{cmr10.tfm}, which is found, +then a few more prolog files (not shown) are referenced, and finally +the Type~1 instance \file{cmr10.pfb} of the font is located and +included in the output file (see last line). +\begin{alltt}\small +kdebug:start search(file=cmr10.tfm, must\_exist=1, find\_all=0, + path=.:~/tex/fonts/tfm//:!!/usr/local/texmf/fonts/tfm//: + /var/tex/fonts/tfm//). +kdebug:search(cmr10.tfm) => /usr/local/texmf/fonts/tfm/public/cm/cmr10.tfm +kdebug:start search(file=texps.pro, must\_exist=0, find\_all=0, + ... +<texps.pro> +kdebug:start search(file=cmr10.pfb, must\_exist=0, find\_all=0, + path=.:~/tex/dvips//:!!/usr/local/texmf/dvips//: + ~/tex/fonts/type1//:!!/usr/local/texmf/fonts/type1//). +kdebug:search(cmr10.pfb) => /usr/local/texmf/fonts/type1/public/cm/cmr10.pfb +<cmr10.pfb>[1] +\end{alltt} + +\subsection{Runtime options} + +Another useful feature of \Webc{} is its possibility to control a number +of memory parameters (in particular, array sizes) via the runtime file +\file{texmf.cnf} read by \KPS{}. The memory settings can be found in +Part 3 of that file in the \TL{} distribution. The more important +are: + +\begin{ttdescription} +\item[\texttt{main\_memory}] + Total words of memory available, for + \TeX{}, \MF{} and \MP. You must make a new format file for each + different setting. For instance, you could generate a ``huge'' + version of \TeX{}, and call the format file \texttt{hugetex.fmt}. + Using the standard way of specifying the program name used by \KPS{}, + the particular value of the \texttt{main\_memory} variable will then + be read from \file{texmf.cnf}. +\item[\texttt{extra\_mem\_bot}] + Extra space for ``large'' \TeX{} data structures: + boxes, glue, breakpoints, etc. Especially useful if you use + \PiCTeX{}. +\item[\texttt{font\_mem\_size}] + Number of words for font information available for \TeX. This + is more or less the total size of all \acro{TFM} files read. +\item[\texttt{hash\_extra}] + Additional space for the hash table of control sequence names. + Only $\approx$10,000 control sequences can be stored in the main + hash table; if you have a large book with numerous cross-references, + this might not be enough. The default value of + \texttt{hash\_extra} is \texttt{50000}. +\end{ttdescription} + +\noindent Of course, this facility is no substitute for truly dynamic +arrays and memory allocation, but since these are extremely difficult to +implement in the present \TeX{} source, these runtime parameters provide +a practical compromise allowing some flexibility. + + +\begin{comment} +\section{Building on a new Unix platform} + +If you have a platform for which executables are not included, you will +need to compile \TeX{} and friends. This is not as hard as it +sounds. What you need is all in the directory \texttt{source} in the +distribution. + +\subsection{Prerequisites} + +You will need at least 100 megabytes of disk space to compile all of +\TeX{} and its support programs. You'll also need an \acro{ANSI} C +compiler, a \cmdname{make} utility, a lexical scanner, and a parser +generator. We recommend the \GNU version of these programs +(\cmdname{gcc}, \GNU \cmdname{make}, \cmdname{m4}, \cmdname{flex}, +\cmdname{bison}). You may be able to work with other C compilers and +\cmdname{make} programs, but you will need a good understanding of +building Unix programs to sort out problems. + +Also, the command \texttt{uname} must return a sensible value. + + +\subsection{Configuration} + +To begin, perform a normal installation of \TL{} to your disk (see +section~\ref{sec:install-disk} on +\p.\pageref{sec:install-disk}). You may wish to skip installing +all of the prebuilt binaries. + +Then, unpack the source from the compressed \texttt{tar} file in the +directory \dirname{source} to your disk and change directory to where +you placed it. + +Next, run \cmdname{configure} with a command line like this: +\begin{alltt} +> \Ucom{sh configure -prefix=/usr/local/TeX} +\end{alltt} + +The \optname{-prefix} directory is the one where you installed the +support tree; the directory layout will be as follows (where \$TEXDIR +stands for the directory you chose): + +\noindent +\begin{tabular}{>{\ttfamily}ll@{}} + \dirname{$TEXDIR/share/texmf} & main tree with fonts,\\ + & \qquad macros, etc\\ + \dirname{$TEXDIR/man} & Unix manual pages\\ + \dirname{$TEXDIR/info} & \GNU style Info manuals\\ + \dirname{$TEXDIR/bin/$PLATFORM} & binaries\\ +\end{tabular} +%$ + +If you want to leave out the \dirname{$PLATFORM} directory level, +i.e., put the binaries directly into \dirname{$TEXDIR/bin}, specify +the \verb|--disable-multiplatform| option to \cmdname{configure}. + +Have a look at the output of \verb|./configure --help| for more +options you can use. For example, you can skip building of \OMEGA{} and +\eTeX{}. + + +\subsection{Running \cmdname{make}} + +Make sure the shell variable or option \texttt{noclobber} is not set. +Then, run the main \cmdname{make} like this: +\begin{alltt} +> \Ucom{make world} +\end{alltt} +and relax\ldots + +Alternatively, you want to log all the output, as in: +\begin{alltt} +> \Ucom{sh -c "make world >world.log 2>\&1" \&} +\end{alltt} + +Before you believe that everything went ok, please check the log file +for errors: \GNU \cmdname{make} always uses the string \samp{***} +whenever a command fails. Also, check if all the programs were built: + +\begin{alltt} +> \Ucom{cd \var{TEXDIR}/bin/\var{archname}} +> \Ucom{ls | wc} +\end{alltt} +The result should be over 200 (you can check the exact number with the +\dirname{bin} directory contents in the distribution). + +If you need special privileges for \texttt{make install}, you can +separate the \samp{make world} into two different runs, like this: +\begin{alltt} +> \Ucom{make all} +> \Ucom{su} +> \Ucom{make install strip} +\end{alltt} + +After you've installed your new binaries, you should follow the normal +post-installation procedures, given in section~\ref{sec:postinstall} +(\p.\pageref{sec:postinstall}). + +Also, if you'd like to make your binaries available to others, please +contact us. We'll be happy to put them on the \TL\ web pages. +\end{comment} + +\htmlanchor{ack} +\section{Acknowledgements} + +\TL{} is a joint effort by virtually all of the \TeX{} user groups. +This edition of \TL{} was overseen by Karl Berry.

The \TL{} documentation web page +is \url{http://tug.org/texlive/doc.html}. + +Of course the most important acknowledgement must go to Donald Knuth, +first for inventing \TeX, and then for giving it to the world. + + + +\section{Release history} +\label{sec:history} + +\subsection{Past} + +Discussion began in late 1993 when the Dutch \TeX{} Users Group was +starting work on its 4All\TeX{} \CD{} for \acro{MS-DOS} users, and it +was hoped at that time to issue a single, rational, \CD{} for all +systems. This was too ambitious a target for the time, but it did spawn +not only the very successful 4All\TeX{} \CD{}, but also the \acro{TUG} +Technical Council working group on a \emph{\TeX{} Directory Structure} +(\url{http://tug.org/tds}), which specified how to create consistent and +manageable collections of \TeX{} support files. A complete draft of the +\TDS{} was published in the December 1995 issue of \textsl{TUGboat}, and +it was clear from an early stage that one desirable product would be a +model structure on \CD{}. The distribution you now have is a very direct +result of the working group's deliberations. It was also clear that the +success of the 4All\TeX{} \CD{} showed that Unix users would benefit +from a similarly easy system, and this is the other main strand of +\TL. + +We first undertook to make a new Unix-based \TDS{} \CD{} in the autumn +of 1995, and quickly identified Thomas Esser's \teTeX{} as the ideal +setup, as it already had multi-platform support and was built with +portability across file systems in mind. Thomas agreed to help, and work +began seriously at the start of 1996. The first edition was released in +May 1996. At the start of 1997, Karl Berry completed a major new release +of Web2c, which included nearly all the features which Thomas Esser had +added in \teTeX, and we decided to base the 2nd edition of the \CD{} on +the standard \Webc, with the addition of \teTeX's \texttt{texconfig} +script. The 3rd edition of the \CD{} was based on a major revision of +\Webc, 7.2, by Olaf Weber; at the same time, a new revision of \teTeX +was being made, and \TL{} included almost all of its features. The +4th edition followed the same pattern, using a new version of \teTeX, +and a new release of \Webc{} (7.3). The system now included a complete +Windows setup. + +For the 5th edition (March 2000) many parts of the \CD{} were revised +and checked, updating hundreds of packages. Package details were stored +in XML files. But the major change for \TeX\ Live 5 was that all +non-free software was removed. Everything in \TL{} is now intended +to be compatible with the Debian Free Software Guidelines +(\url{http://www.debian.org/intro/free}); we have done our best to check +the license conditions of all packages, but we would very much +appreciate hearing of any mistakes. + +The 6th edition (July 2001) had much more material updated. The major +change was a new install concept: the user could select a more exact set +of needed collections. Language-related collections were completely +reorganized, so selecting any of them installs not only macros, fonts, +etc., but also prepares an appropriate \texttt{language.dat}. + +The 7th edition of 2002 had the notable addition of \MacOSX{} support, +and the usual myriad of updates to all sorts of packages and +programs. An important goal was integration of the source back with +\teTeX, to correct the drift apart in versions~5 and~6. + +\subsubsection{2003} + +In 2003, with the continuing flood of updates and additions, we found +that \TL{} had grown so large it could no longer be contained on a +single \CD, so we split it into three different distributions (see +section~\ref{sec:tl-coll-dists}, \p.\pageref{sec:tl-coll-dists}). In +addition: + +\begin{itemize*} +\item At the request of the \LaTeX{} team, we changed the standard + \cmdname{latex} and \cmdname{pdflatex} commands to now use \eTeX{} (see + \p.\pageref{text:etex}). +\item The new Latin Modern fonts were included (and are recommended). +\item Support for Alpha \acro{OSF} was removed + (\acro{HPUX} support was removed previously), since no one had (or + volunteered) hardware available on which to compile new binaries. +\item Windows setup was substantially changed; for the first time + an integrated environment based on XEmacs was introduced. +\item Important supplementary programs for Windows + (Perl, Ghost\-script, Image\-Magick, Ispell) are now installed + in the \TL{} installation directory. +\item Font map files used by \cmdname{dvips}, \cmdname{dvipdfm} + and \cmdname{pdftex} are now generated by the new program + \cmdname{updmap} and installed into \dirname{texmf/fonts/map}. +\item \TeX{}, \MF{}, and \MP{} now, by default, output most input + characters (32 and above) as themselves in output (e.g., + \verb|\write|) files, + log files, and the terminal, i.e., \emph{not} translated using the + \verb|^^| notation. In \TL{}~7, this translation was + dependent on the system locale settings; now, locale settings do + not influence the \TeX{} programs' behavior. If for some reason + you need the \verb|^^| output, rename the file + \verb|texmf/web2c/cp8bit.tcx|. (Future releases will have cleaner + ways to control this.) +\item This documentation was substantially revised. +\item Finally, since the edition numbers had grown unwieldy, + the version is now simply identified by the year: \TL{} 2003. +\end{itemize*} + + +\subsubsection{2004} + +2004 saw many changes: + +\begin{itemize} + +\item If you have locally-installed fonts which use their own +\filename{.map} or (much less likely) \filename{.enc} support files, you +may need to move those support files. + +\filename{.map} files are now searched for in subdirectories of +\dirname{fonts/map} only (in each \filename{texmf} tree), along the +\envname{TEXFONTMAPS} path. Similarly, \filename{.enc} files are now +searched for in subdirectories of \dirname{fonts/enc} only, along the +\envname{ENCFONTS} path. \cmdname{updmap} will attempt to warn about +problematic files. + +For methods of handling this and other information, please see +\url{http://tug.org/texlive/mapenc.html}. + +\item The \TK\ has been expanded with the addition of a \MIKTEX-based +installable \CD, for those who prefer that implementation to Web2C. +See section~\ref{sec:overview-tl} (\p.\pageref{sec:overview-tl}). + +\item Within \TL, the single large \dirname{texmf} tree of previous +releases has been replaced by three: \dirname{texmf}, +\dirname{texmf-dist}, and \dirname{texmf-doc}. See +section~\ref{sec:tld} (\p.\pageref{sec:tld}), and the \filename{README} +files for each. + +\item All \TeX-related input files are now collected in +the \dirname{tex} subdirectory of \dirname{texmf*} trees, rather than +having separate sibling directories \dirname{tex}, \dirname{etex}, +\dirname{pdftex}, \dirname{pdfetex}, etc. See +\CDref{texmf-doc/doc/english/tds/tds.html\#Extensions} +{\texttt{texmf-doc/doc/english/tds/tds.html\#Extensions}}. + +\item Helper scripts (not meant to be invoked by users) are now located +in a new \dirname{scripts} directory of \dirname{texmf*} trees, and +searched for via \verb|kpsewhich -format=texmfscripts|. So if you have +programs which call such scripts, they'll need to be adjusted. See +\CDref{texmf-doc/doc/english/tds/tds.html\#Scripts} +{\texttt{texmf-doc/doc/english/tds/tds.html\#Scripts}}. + +\item Almost all formats leave most characters printable as +themselves via the ``translation file'' \filename{cp227.tcx}, instead of +translating them with the \verb|^^| notation. Specifically, characters +at positions 32--256, plus tab, vertical tab, and form feed are +considered printable and not translated. The exceptions are plain \TeX\ +(only 32--126 printable), \ConTeXt\ (0--255 printable), and the +\OMEGA-related formats. This default behavior is almost the same as in +\TL\,2003, but it's implemented more cleanly, with more possibilities +for customization. See \CDref{texmf/doc/web2c/web2c.html\#TCX-files} +{\texttt{texmf/doc/web2c/web2c.html\#TCX-files}}. +(By the way, with Unicode input, \TeX\ may output partial character +sequences when showing error contexts, since it is byte-oriented.) + +\item \textsf{pdfetex} is now the default engine for all formats +except (plain) \textsf{tex} itself. (Of course it generates \acro{DVI} +when run as \textsf{latex}, etc.) This means, among other things, that +the microtypographic features of \textsf{pdftex} are available in +\LaTeX, \ConTeXt, etc., as well as the \eTeX\ features +(\OnCD{texmf-dist/doc/etex/base/}). + +It also means it's \emph{more important than ever} to use the +\pkgname{ifpdf} package (works with both plain and \LaTeX) or equivalent +code, because simply testing whether \cs{pdfoutput} or some other +primitive is defined is not a reliable way to determine if \acro{PDF} +output is being generated. We made this backward compatible as best we +could this year, but next year, \cs{pdfoutput} may be defined even when +\acro{DVI} is being written. + +\item pdf\TeX\ (\url{http://pdftex.org}) has many new features: + + \begin{itemize*} + + \item \cs{pdfmapfile} and \cs{pdfmapline} provide font map support + from within a document. + + \item Microtypographic font expansion can be used more easily.\\ + \url{http://www.ntg.nl/pipermail/ntg-pdftex/2004-May/000504.html} + + \item All parameters previously set through the special configuration + file \filename{pdftex.cfg} must now be set through primitives, + typically in \filename{pdftexconfig.tex}; \filename{pdftex.cfg} is no + longer supported. Any extant \filename{.fmt} files must be redumped + when \filename{pdftexconfig.tex} is changed. + + \item See the pdf\TeX\ manual for more: \OnCD{texmf-dist/doc/pdftex/manual/pdftex-a.pdf}. + + \end{itemize*} + +\item The \cs{input} primitive in \cmdname{tex} (and \cmdname{mf} and +\cmdname{mpost}) now accepts double quotes containing spaces and other +special characters. Typical examples: +\begin{verbatim} +\input "filename with spaces" % plain +\input{"filename with spaces"} % latex +\end{verbatim} +See the Web2C manual for more: \OnCD{texmf/doc/web2c}. + +\item enc\TeX\ support is now included within Web2C and consequently all +\TeX\ programs, via the \optname{-enc} option\Dash \emph{only when +formats are built}. enc\TeX\ supports general re-encoding of input and +output, enabling full support of Unicode (in \acro{UTF}-8). See +\OnCD{texmf-dist/doc/generic/enctex/} and +\url{http://www.olsak.net/enctex.html}. + +\item Aleph, a new engine combining \eTeX\ and \OMEGA, is available. +A little information is available in \OnCD{texmf-dist/doc/aleph/base} +and \url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=aleph}. The +\LaTeX-based format for Aleph is named \textsf{lamed}. + +\item The latest \LaTeX\ release has a new version of the +\acro{LPPL}\Dash now officially a Debian-approved license. Assorted +other updates, see the \filename{ltnews} files in +\OnCD{texmf-dist/doc/latex/base}. + +\item \cmdname{dvipng}, a new program for converting \acro{DVI} to +\acro{PNG} image files, is included. See \OnCD{texmf/doc/man/man1/dvipng.1}. + +\item We reduced the \pkgname{cbgreek} package to a ``medium'' sized set +of fonts, with the assent and advice of the author (Claudio Beccari). +The excised fonts are the invisible, outline, and transparency ones, +which are relatively rarely used, and we needed the space. The full set +is of course available from \acro{CTAN} +(\url{http://www.ctan.org/tex-archive/fonts/greek/cb}). + +\item \cmdname{oxdvi} has been removed; just use \cmdname{xdvi}. + +\item The \cmdname{ini} and \cmdname{vir} commands (links) for +\cmdname{tex}, \cmdname{mf}, and \cmdname{mpost} are no longer created, +such as \cmdname{initex}. The \cmdname{ini} functionality has been +available through the command-line option \optname{-ini} for years now. + +\item \textsf{i386-openbsd} platform support was removed. Since the +\pkgname{tetex} package in the \acro{BSD} Ports system is available, and +\acro{GNU/}Linux and Free\acro{BSD} binaries were available, it seemed +volunteer time could be better spent elsewhere. + +\item On \textsf{sparc-solaris} (at least), you may have to set the +\envname{LD\_LIBRARY\_PATH} environment variable to run the +\pkgname{t1utils} programs. This is because they are compiled with C++, +and there is no standard location for the runtime libraries. (This is +not new in 2004, but wasn't previously documented.) Similarly, on +\textsf{mips-irix}, the \acro{MIPS}pro 7.4 runtimes are required. + +\end{itemize} + +\subsubsection{2005} + +2005 saw the usual huge number of updates to packages and programs. +The infrastructure stayed relatively stable from 2004, but inevitably +there were some changes there as well: + +\begin{itemize} + +\item New scripts \cmdname{texconfig-sys}, \cmdname{updmap-sys}, and + \cmdname{fmtutil-sys} were introduced, which modify the + configuration in the system trees. The \cmdname{texconfig}, + \cmdname{updmap}, and \cmdname{fmtutil} scripts now modify + user-specific files, under \dirname{$HOME/.texlive2005}. + +\item Corresponding new variables \envname{TEXMFCONFIG} and + \envname{TEXMFSYSCONFIG} to specify the trees where configuration + files (user or system, respectively) are found. Thus, you may + need to move personal versions of \filename{fmtutil.cnf} and + \filename{updmap.cfg} to these places; another option is to + redefine \envname{TEXMFCONFIG} or \envname{TEXMFSYSCONFIG} in + \filename{texmf.cnf}. In any case the real location of these files + and the values of \envname{TEXMFCONFIG} and \envname{TEXMFSYSCONFIG} + must agree. + See section~\ref{sec:texmftrees}, \p.\pageref{sec:texmftrees}. + +\item Last year, we kept \verb|\pdfoutput| and other primitives undefined + for \dvi\ output, even though the \cmdname{pdfetex} program was + being used. This year, as promised, we undid that compatibility + measure. So if your document uses \verb|\ifx\pdfoutput\undefined| + to test if PDF is being output, it will need to be changed. You + can use the package \pkgname{ifpdf.sty} (which works under both + plain \TeX\ and \LaTeX) to do this, or steal its logic. + +\item Last year, we changed most formats to output (8-bit) characters as + themselves (see previous section). The new TCX file + \filename{empty.tcx} now provides an easier way to get the + original \verb|^^| notation if you so desire, as in: +\begin{verbatim} +latex --translate-file=empty.tcx yourfile.tex +\end{verbatim} + +\item The new program \cmdname{dvipdfmx} is included for translation of + DVI to PDF; this is an actively maintained update of + \cmdname{dvipdfm} (which is also still available for now, though + no longer recommended). + +\item The new programs \cmdname{pdfopen} and \cmdname{pdfclose} are included + to allow reloading of pdf files in the Adobe Acrobat Reader without + restarting the program. (Other pdf readers, notably \cmdname{xpdf}, + \cmdname{gv}, and \cmdname{gsview}, have never suffered from this + problem.) + +\item For consistency, the variables \envname{HOMETEXMF} and + \envname{VARTEXMF} have been renamed to \envname{TEXMFHOME} and + \envname{TEXMFSYSVAR}, respectively. There is also + \envname{TEXMFVAR}, which is by default user-specific. See the + first point above. + +\end{itemize} + + +\subsubsection{2006--2007} + +In 2006--2007, the major new addition to \TL{} was the \XeTeX{} program, +available as the \texttt{xetex} and \texttt{xelatex} programs; see +\url{http://scripts.sil.org/xetex}. + +MetaPost also received a notable update, with more planned for the +future (\url{http://tug.org/metapost/articles}), likewise pdf\TeX{} +(\url{http://tug.org/applications/pdftex}). + +The \TeX\ \filename{.fmt} (high-speed format) and the similar files for +MetaPost and \MF\ are now stored in subdirectories of \dirname{texmf/web2c}, +instead of in the directory itself (although the directory is still +searched, for the sake of existing \filename{.fmt}'s). The +subdirectories are named for the `engine' in use, such as \filename{tex} +or \filename{pdftex} or \filename{xetex}. This change should be +invisible in normal use. + +The (plain) \texttt{tex} program no longer reads \texttt{\%\&} first +lines to determine what format to run; it is the pure Knuthian \TeX. +(\LaTeX\ and everything else do still read \texttt{\%\&} lines). + +Of course the year also saw (the usual) hundreds of other updates to +packages and programs. As usual, please check \acro{CTAN} +(\url{http://www.ctan.org}) for updates. + +Internally, the source tree is now stored in Subversion, with a standard +web interface for viewing the tree, as linked from our home page. +Although not visible in the final distribution, we expect this will +provide a stable development foundation for future years. + +Finally, in May 2006 Thomas Esser announced that he would no longer be +updating te\TeX{} (\url{http://tug.org/tetex}). As a result, there was +been a surge of interest in \TL{}, especially among \GNU/Linux +distributors. (There is a new \texttt{tetex} installation scheme in +\TL{}, which provides an approximate equivalent.) We hope this will +eventually translate to improvements in the \TeX\ environment for +everyone. + +\medskip \noindent +Final note on the past: all releases of \TL{}, along with ancillary +material such as \CD\ labels, are available at +\url{ftp://tug.org/historic/systems/texlive}. + +\htmlanchor{news} +\subsection{Present} +\label{sec:tlcurrent} + +In 2008, the entire \TL{} infrastructure was redesigned and +reimplemented. Complete information about an installation is now stored +in a plain text file \filename{tlpkg/texlive.tlpdb}. + +Among other things, this finally makes possible upgrading a \TL{} +installation over the Internet after the initial installation, a feature +MiK\TeX\ has provided for many years. We expect to regularly update new +packages as they are released to \CTAN. + +The major new engine Lua\TeX\ (\url{http://luatex.org}) is included; +besides a new level of flexibility in typesetting, this provides an +excellent scripting language for use both inside and outside of \TeX\ +documents. + +Support among Windows and the Unix-based platforms is now much more +uniform. In particular, most Perl and Lua scripts are now available on +Windows, using the Perl internally distributed with \TL. + +The new \cmdname{tlmgr} script (section~\ref{sec:tlmgr}) is the +general interface for managing \TL{} after the initial installation. +It handles package updates and consequent regeneration of formats, map +files, and language files, optionally including local additions. + +With the advent of \cmdname{tlmgr}, the \cmdname{texconfig} actions to +edit the format and hyphenation configuration files are now disabled. + +The \cmdname{xindy} indexing program +(\url{http://xindy.sourceforge.net/}) is now included on most platforms. + +The \cmdname{kpsewhich} tool can now report all matches for a given file +(option \optname{--all}) and limit matches to a given subdirectory +(option \optname{--subdir}). + +The \cmdname{dvipdfmx} program now includes functionality to extract +bounding box information, via the command name \cmdname{extractbb}; this +was one of the last features provided by \cmdname{dvipdfm} not in +\cmdname{dvipdfmx}. + +The font aliases \filename{Times-Roman}, \filename{Helvetica}, and so on +have been removed. Different packages expected them to behave +differently (in particular, to have different encodings), and there was +no good way to resolve this. + +The \pkgname{platex} format has been removed, to resolve a name conflict +with a completely different Japanese \pkgname{platex}; the +\pkgname{polski} package is now the main Polish support. + +Internally, the \web\ string pool files are now compiled into the +binaries, to ease upgrades. + +Finally, the changes made by Donald Knuth in his `\TeX\ tuneup of 2008' +are included in this release. See +\url{http://tug.org/TUGboat/Articles/tb29-2/tb92knut.pdf}. + + +\subsection{Future} + +\emph{\TL{} is not perfect!} (And never will be.) We intend to +continue to release new versions, and would like to provide more help +material, more utilities, more installation programs, and (of course) an +ever-improved and better-checked tree of macros and fonts. This work is +all done by hard-pressed volunteers in their limited spare time, and a +great deal remains to be done.
