+\section{Introduction}
+\label{sec:intro}
+
+\subsection{\protect\TeX\protect\ Live and the \protect\TeX\protect\ Collection}
+
+This document describes the main features of the \TL{} software
+distribution\Dash \TeX{} and related programs for \GNU/Linux
+and other Unix flavors, \MacOSX, and Windows systems.
+
+You may have acquired \TL{} by downloading, or on the \TK{} \DVD, which
+\TeX{} user groups distribute among their members, or in other ways.
+Section \ref{sec:tl-coll-dists} briefly describes the contents of the
+\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.
+
+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}).
+
+
+\htmlanchor{platforms}
+\subsection{Operating system support}
+\label{sec:os-support}
+
+\TL{} contains binaries for many Unix-based platforms, including
+\GNU/Linux, \MacOSX, and Cygwin.  The included sources can be compiled
+on platforms for which we do not provide binaries.
+
+As to Windows: Windows~7 and later are supported. Windows Vista, XP
+and 2000 will probably still mostly work.  There are no special
+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
+(\url{http://tug.org/texlive/acquire.html}). The net installer itself is
+small, and downloads everything requested from the Internet.
+
+The \DVD{} installer lets you install to a local disk.  You cannot run
+\TL{} directly from the \TK{} \DVD{} (or its \code{.iso} image), but you
+can prepare a runnable installation on, e.g., a \USB{} stick (see
+section~\ref{sec:portable-tl}).  Installation is described in later
+sections (\p.\pageref{sec:install}), but here is a quick start:
+
+\begin{itemize*}
+
+\item The installation script is named \filename{install-tl}.  It can
+  operate in a ``wizard mode'' given the option \code{-gui=wizard}
+  (default for Windows), a text mode given \code{-gui=text} (default for
+  everything else), and an expert \GUI{} mode given \code{-gui=perltk}.
+
+\item One of the installed items is the `\TL\ Manager' program,
+  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*}
+
+
+\htmlanchor{security}
+\subsection{Security considerations}
+\label{sec:security}
+
+To the best of our knowledge, the core \TeX\ programs themselves are
+(and always have been) extremely robust.  However, the contributed
+programs in \TeX\ Live may not reach the same level, despite everyone's
+best efforts.  As always, you should be careful when running programs on
+untrusted input; for maximum safety, use a new subdirectory.
+
+This need for care is especially urgent on Windows, since in general
+Windows finds programs in the current directory before anything else,
+regardless of the search path.  This opens up a wide variety of possible
+attacks.  We have closed many holes, but undoubtedly some remain,
+especially with third-party programs.  Thus, we recommend checking for
+suspicious files in the current directory, especially executables
+(binaries or scripts).  Ordinarily they should not be present, and
+definitely should not normally be created by merely processing a document.
+
+Finally, \TeX\ (and its companion programs) are able to write files when
+processing documents, a feature that can also be abused in a wide
+variety of ways.  Again, processing unknown documents in a new
+subdirectory is the safest bet.
+
+
+\subsection{Getting help}
+\label{sec:help}
+
+The \TeX{} community is 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 forgo \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{} FAQ] The \TeX{} 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-dist/doc/generic/FAQ-en/}, 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://mirror.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] Principal support forums include the
+Usenet newsgroup \url{news:comp.text.tex}, the mailing list
+\email{texhax@tug.org}, and \url{http://tex.stackexchange.com}, a
+collaboratively edited question and answer site.  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 FAQ entry, to maximize
+your chances of getting a useful answer:
+\url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=askquestion}.
+Also worth mentioning are the \LaTeX{} Community site at
+\url{http://www.latex-community.org/} and its forum
+\url{http://www.latex-community.org/forum/}, and 
+\TeX\ StackExchange at \url{http://tex.stackexchange.com/}.
+
+\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: \protect\TL,
+           pro\protect\TeX{}t, Mac\protect\TeX}
+\label{sec:tl-coll-dists}
+
+The \TK{} \DVD{} comprises the following:
+
+\begin{description}
+
+\item [\TL] A complete \TeX{} system to be installed to disk.  Home
+page: \url{http://tug.org/texlive/}.
+
+\item [Mac\TeX] for \MacOSX, this adds a native \MacOSX\ installer and other
+Mac applications to \TL{}.  Home page:
+\url{http://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.  Home page:
+\url{http://tug.org/protext/}.
+
+\item [CTAN] A snapshot of the \CTAN{} repository (\url{http://www.ctan.org/}).
+
+\end{description}
+
+\CTAN{} and \pkgname{protext} do not follow the same copying conditions
+as \TL{}, so be careful when redistributing or modifying.
+
+
+\subsection{Top level \protect\TL{} directories}
+\label{sec:tld}
+
+Here is a brief listing and description of the top level directories in a
+\TL{} installation.  
+
+\begin{ttdescription}
+\item[bin] The \TeX{} system programs, arranged by platform.
+%
+\item[readme-*.dir] Quick overview and useful links for \TL{},
+in various languages, in both \HTML{} and plain text.
+%
+\item[source] The source to all included programs, including the main
+  \Webc{}-based \TeX{} distributions.
+%
+\item[texmf-dist] The principal tree; see \dirname{TEXMFDIST} below.
+%
+\item[tlpkg] Scripts, programs and data for managing the
+  installation, and special support for Windows.
+\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.
+
+For documentation, the comprehensive links in the top-level file
+\OnCD{doc.html} may be helpful.  The documentation for nearly everything
+(packages, formats, fonts, program manuals, man pages, Info files) is in
+\dirname{texmf-dist/doc}.  You can use the \cmdname{texdoc} program to
+find documentation wherever it is located.
+
+This \TL\ documentation itself is in \dirname{texmf-dist/doc/texlive},
+available in several languages:
+
+\begin{itemize*}
+\item{Czech/Slovak:} \OnCD{texmf-dist/doc/texlive/texlive-cz}
+\item{German:} \OnCD{texmf-dist/doc/texlive/texlive-de}
+\item{English:} \OnCD{texmf-dist/doc/texlive/texlive-en}
+\item{French:} \OnCD{texmf-dist/doc/texlive/texlive-fr}
+\item{Italian:} \OnCD{texmf-dist/doc/texlive/texlive-it}
+\item{Polish:} \OnCD{texmf-dist/doc/texlive/texlive-pl}
+\item{Russian:} \OnCD{texmf-dist/doc/texlive/texlive-ru}
+\item{Serbian:} \OnCD{texmf-dist/doc/texlive/texlive-sr}
+\item{Simplified Chinese:} \OnCD{texmf-dist/doc/texlive/texlive-zh-cn}
+\end{itemize*}
+
+\subsection{Overview of the predefined texmf trees}
+\label{sec:texmftrees}
+
+This section lists the predefined variables specifying the texmf trees
+used by the system, and their intended purpose, and the default layout
+of \TL{}. The command \texttt{tlmgr~conf} shows the values of these
+variables, so that you can easily find out how they map to particular
+directories in your installation.
+
+All of the trees, including the personal ones, should follow the \TeX\
+Directory Structure (\TDS, \url{http://tug.org/tds}), with all its
+myriad subdirectories, or files may not be found.  Section
+\ref{sec:local-personal-macros} (\p.\pageref{sec:local-personal-macros})
+describes this in more detail.  The order here is the reverse order in
+which the trees are searched, that is, later trees in the list override
+earlier ones.
+
+\begin{ttdescription}
+\item [TEXMFDIST] The tree which holds nearly all of the files in the original
+  distribution---configuration files, scripts, packages, fonts, etc.
+  (The main exception are the per-platform executables, which are stored
+  in a sibling directory \code{bin/}.)
+\item [TEXMFLOCAL] The tree which administrators can use for system-wide
+  installation of additional or updated macros, fonts, etc.
+\item [TEXMFSYSVAR] The (site-wide) 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.
+\item [TEXMFSYSCONFIG] The (site-wide) tree used by the utilities
+  \verb+texconfig-sys+, \verb+updmap-sys+, and \verb+fmtutil-sys+ to
+  store modified configuration data.
+\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 [TEXMFVAR] The (personal) tree used by \verb+texconfig+,
+  \verb+updmap+ and \verb+fmtutil+ to store (cached) runtime data such
+  as format files and generated map files.
+\item [TEXMFCONFIG] The (personal) tree used by the utilities
+  \verb+texconfig+, \verb+updmap+, and \verb+fmtutil+ to store modified
+  configuration data.
+\item [TEXMFCACHE] The tree(s) used by \ConTeXt\ MkIV and Lua\LaTeX\
+  to store (cached) runtime data; defaults to \code{TEXMFSYSVAR},
+  or (if that's not writable), \code{TEXMFVAR}.
+\end{ttdescription}
+
+\noindent
+The default layout is:
+\begin{description}
+  \item[system-wide root] can span multiple \TL{} releases:
+  \begin{ttdescription}
+    \item[2016] A previous release.
+    \item[2017] The current release.
+    \begin{ttdescription}
+      \item [bin] ~

+\subsection{Extensions to \protect\TeX}
+\label{sec:tex-extensions}
+
+Knuth's original \TeX{} itself is frozen, apart from rare bug fixes. It
+is present in \TL\ as the program \prog{tex}, and will remain so
+for the foreseeable future.  \TL{} also contains several extended versions of
+\TeX\ (also known as \TeX\ engines):
+
+\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 PDF output as well as \dvi{}, and many non-output-related
+extensions.  This is the program invoked for most formats, e.g.,
+\prog{etex}, \prog{latex}, \prog{pdflatex}.  Its web site is
+\url{http://www.pdftex.org/}.  See
+\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,
+and is mostly (but not entirely) backward-compatible.  It is also
+intended to be a functional superset of Aleph (see below), though
+technical compatibility is not intended. The incorporated Lua
+interpreter (\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.  Its web site is \url{http://www.luatex.org/}, and the
+reference manual is \OnCD{texmf-dist/doc/luatex/base/luatex.pdf}.
+
+\item [\XeTeX] adds support for Unicode input and OpenType- and system
+fonts, implemented using standard third-party libraries.  See
+\url{http://tug.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' (OTPs),
+for performing complex transformations on arbitrary input.  Omega is no
+longer included in \TL{} as a separate program; only Aleph is provided:
+
+\item [Aleph] combines the \OMEGA\ and \eTeX\ extensions.
+See \OnCD{texmf-dist/doc/aleph/base}.
+
+\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, xindy] index support.
+
+\item [dvips] convert \dvi{} to \PS{}.
+
+\item [xdvi] \dvi{} previewer for the X Window System.
+
+\item [dviconcat, dviselect] cut and paste pages
+from \dvi{} files.
+
+\item [dvipdfmx] convert \dvi{} to PDF, an alternative approach
+to pdf\TeX\ (mentioned above).
+
+\item [psselect, psnup, \ldots] \PS{} utilities.
+
+\item [pdfjam, pdfjoin, \ldots] PDF utilities.
+
+\item [context, mtxrun] Con\TeX{}t and PDF processor.
+
+\item [htlatex, \ldots] \cmdname{tex4ht}: \AllTeX{} to HTML (and
+XML and more) converter.
+
+\end{cmddescription}

+\htmlanchor{installation}
+\section{Installation}
+\label{sec:install}
+
+\subsection{Starting the installer}
+\label{sec:inst-start}
+
+To begin, get the \TK{} \DVD{} or download the \TL{} net installer.  See
+\url{http://tug.org/texlive/acquire.html} for more information and other
+methods of getting the software.
+
+\begin{description}
+\item [Net installer, .zip or .tar.gz:] Download from \CTAN, under
+\dirname{systems/texlive/tlnet}; the url
+\url{http://mirror.ctan.org/systems/texlive/tlnet} should redirect to a
+nearby, up-to-date, mirror.  You can retrieve either
+\filename{install-tl.zip} which can be used under Unix and Windows, or
+the considerably smaller \filename{install-unx.tar.gz} for Unix
+only. After unpacking, \filename{install-tl} and
+\filename{install-tl-windows.bat} will be in the \dirname{install-tl}
+subdirectory.
+
+\item[Net installer, Windows .exe:] Download from \CTAN{} as above,
+and double-click. This starts up a first-stage installer and unpacker;
+see figure~\ref{fig:nsis}. It gives three choices: ``Simple install''
+starts up the wizard installer, ``Custom install'' the expert \GUI{}
+installer, as described in section~\ref{sec:wininst}. A third option is
+just unpacking.
+
+\item [\TeX{} Collection \DVD:] go to the \DVD's \dirname{texlive}
+subdirectory. Under Windows, the installer normally starts 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.
+You can also mount the \ISO\ directly on most systems.  After installing
+from \DVD\ or \ISO, if you want to get continuing updates from the
+Internet, please see \ref{sec:dvd-install-net-updates}.
+
+\end{description}
+
+\begin{figure}[tb]
+\tlpng{nsis_installer}{.6\linewidth}
+\caption{First stage of Windows .exe installer}\label{fig:nsis}
+\end{figure}
+
+The same installer program is run, whatever the source.  The most
+visible difference between the two is that with the net installer, what
+you end up with is the packages that are currently available.  This is
+in contrast to the \DVD\ and \ISO\ images, which are not updated between
+the major public releases.
+
+If you need to download through proxies, use a \filename{~/.wgetrc} file
+or environment variables with the proxy settings for Wget
+(\url{http://www.gnu.org/software/wget/manual/html_node/Proxies.html}).
+\TL{} always uses \GNU\ Wget to download.  Of course, this should not
+matter if you are installing from the \DVD\ or \ISO\ image.
+
+\noindent
+The following sections explain installer start-up in more detail.
+
+\subsubsection{Unix}
+
+Below, \texttt{>} denotes the shell prompt; user input is
+\Ucom{\texttt{bold}}.
+The script \filename{install-tl} is a Perl script.  The simplest way
+to start it on a Unix-compatible system is as follows:
+\begin{alltt}
+> \Ucom{perl /path/to/installer/install-tl}
+\end{alltt}
+(Or you can invoke \Ucom{/path/to/installer/install-tl} if it stayed
+executable, or \texttt{cd} to the directory first, etc.; we won't repeat
+all the variations.)  You may have to enlarge your terminal window so
+that it shows the full text installer screen
+(figure~\ref{fig:text-main}).
+
+To install in expert \GUI\ mode (figure~\ref{fig:gui-main}), you'll
+need the \dirname{Perl::TK} module compiled with XFT support,
+which is generally the case with \GNU/Linux, but often not so with other
+systems.  Given that, you can run:
+\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.
+
+\textbf{Special considerations for Cygwin:} Unlike other
+Unix-compatible systems, Cygwin does not by default include all of the
+prerequisite programs needed by the \TL{} installer.  See
+Section~\ref{sec:cygwin}.
+
+
+\subsubsection{\MacOSX}
+\label{sec:macosx}
+
+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 makes a few
+Mac-specific adjustments, in particular to allow easily switching
+between the various \TeX\ distributions for \MacOSX\ (Mac\TeX, Fink,
+MacPorts, \ldots) using the so-called \TeX{}Dist data structure.
+
+Mac\TeX\ is firmly based on \TL, and the main \TeX\ trees and binaries
+are precisely the same.  It adds a few extra folders with Mac-specific
+documentation and applications.
+
+
+\subsubsection{Windows}\label{sec:wininst}
+
+If you are using the unpacked downloaded zip file, or the \DVD\
+installer failed to start automatically, double-click
+\filename{install-tl-windows.bat}.  If you want more customization
+options, e.g., selection of specific package collections, run
+\filename{install-tl-advanced.bat} instead.
+
+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-windows}

+\subsubsection{Cygwin}
+\label{sec:cygwin}
+
+Before beginning the installation, use Cygwin's \filename{setup.exe} program to
+install the \filename{perl} and \filename{wget} packages if you have
+not already done so.  The following additional packages are
+recommended:
+\begin{itemize*}
+\item \filename{fontconfig} [needed by \XeTeX\ and Lua\TeX]
+\item \filename{ghostscript} [needed by various utilities]
+\item \filename{libXaw7} [needed by \code{xdvi}]
+\item \filename{ncurses} [provides the \code{clear} command used by the installer]
+\end{itemize*}
+
+
+\subsubsection{The text installer}
+
+Figure~\ref{fig:text-main} displays the main text mode screen under
+Unix.  The text installer is the default on 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.
+
+\subsubsection{The expert graphical installer}
+
+Figure~\ref{fig:gui-main} displays the expert graphical installer under
+\GNU/Linux.  Other than using buttons and menus, this does
+not differ much from the text installer.
+
+This mode can be invoked explicitly with
+\begin{alltt}
+> \Ucom{install-tl -gui=perltk}
+\end{alltt}
+
+
+\subsubsection{The simple wizard installer}
+
+Under Windows, the default is to run the simplest installation method we
+could devise, called the ``wizard'' installer
+(figure~\ref{fig:wizard-w32}).  It installs everything and asks almost
+no questions.  If you want to customize your setup, you should run one
+of the other installers.
+
+On other platforms, this mode can be invoked explicitly with
+\begin{alltt}
+> \Ucom{install-tl -gui=wizard}
+\end{alltt}
+
+
+\subsection{Running the installer}
+\label{sec:runinstall}
+
+The installer is intended to be mostly self-explanatory, but following are a
+few notes about the various options and submenus.
+
+\subsubsection{Binary systems menu (Unix only)}
+\label{sec:binary}
+
+\begin{figure}[tb]
+\begin{boxedverbatim}

+   u [ ] Solaris on x86_64 (x86_64-solaris)
+   v [ ] Windows (win32)
+\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
+platforms as well.  This can be useful if you are sharing a \TeX\
+tree across a network of heterogeneous machines, or for a dual-boot
+system.
+
+\subsubsection{Selecting what is to be installed}
+\label{sec:components}
+
+\begin{figure}[tbh]
+\begin{boxedverbatim}
+Select scheme:
+===============================================================================
+ a [X] full scheme (everything)
+ b [ ] medium scheme (small + more packages and languages)
+ c [ ] small scheme (basic + xetex, metapost, a few languages)
+ d [ ] basic scheme (plain and latex)
+ e [ ] minimal scheme (plain only)
+ f [ ] ConTeXt scheme
+ g [ ] GUST TeX Live scheme
+ h [ ] infrastructure-only scheme (no TeX at all)
+ i [ ] teTeX scheme (more than medium, but nowhere near full)
+ j [ ] custom selection of collections
+\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.  This
+is recommended, 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}[tb]
+\centering \tlpng{stdcoll}{.7\linewidth}
+\caption{Collections menu}\label{fig:collections-gui}
+\end{figure}
+
+You can refine your scheme selection with the `collections' menu
+(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 \TeX\ Live Manager (\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 installation directory is
+\dirname{/usr/local/texlive/2017} on Unix and
+|%SystemDrive%\texlive\2017| on Windows.  This arrangement enables
+having many parallel \TL\ installations, such as one for each release
+(typically by year, as here), and you can switch between them merely by
+altering your search path.
+
+That installation directory can be overridden by setting the so-called
+\dirname{TEXDIR} in the installer.  The \GUI\ screen for this and other
+options is shown in figure~\ref{fig:gui-main}.  The most common reasons
+to change it are either lacking enough disk space in that partition (the
+full \TL\ needs several gigabytes), or lacking write permission for the
+default location (you don't have to be root or administrator to install
+\TL, but you do need write access to the target directory).
+
+The installation directories can also be changed by setting a variety of
+environment variables before running the installer (most likely,
+\envname{TEXLIVE\_INSTALL\_PREFIX} or
+\envname{TEXLIVE\_INSTALL\_TEXDIR}); see the documentation from
+|install-tl --help| (available online at
+\url{http://tug.org/texlive/doc/install-tl.html}) for the full list and
+more details.
+
+A reasonable alternative destination is a directory under your home,
+especially if you will be the sole user. Use `|~|' to indicate this, as
+in `|~/texlive/2017|'.
+
+We recommend including the year in the name, to enable keeping different
+releases of \TL{} side by side.  (You may wish to also maintain a
+version-independent name, such as \dirname{/usr/local/texlive-cur}, via a
+symbolic link, which you can then repoint 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
+the user running \TeX.  It expands to \dirname{$HOME} on Unix and
+\verb|%USERPROFILE%| on Windows.  Special redundant note:
+\envname{TEXMFHOME}, like all trees, must be organized according to the
+\TDS, or files may not be found.
+
+\dirname{TEXMFVAR} is the location for storing most cached runtime data
+specific to each user.  \dirname{TEXMFCACHE} is the variable name used
+for that purpose by Lua\LaTeX and \ConTeXt\ MkIV (see
+section~\ref{sec:context-mkiv}, \p.\pageref{sec:context-mkiv}); its
+default value is \dirname{TEXMFSYSVAR}, or (if that's not writable),
+\dirname{TEXMFVAR}.
+
+

+\end{boxedverbatim}
+\caption{Options menu (Unix)}\label{fig:options-text}
+\end{figure}
+
+Figure~\ref{fig:options-text} shows the text mode options menu.
+More info on each:
+
+\begin{description}
+\item[use letter size instead of A4 by default:] The default paper
+  size selection.  Of course, individual documents can and should
+  specify a specific paper size, if desired.
+
+\item[execution of restricted list of programs:] As of \TL\ 2010,
+  execution of a few external programs is allowed by default.  The (very
+  short) list of allowed programs is given in the \filename{texmf.cnf}.
+  See the 2010 news (section~\ref{sec:2010news}) for more details.
+
+\item[create 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 you could end up with incompatible format files.
+
+\item[install font/macro \ldots\ tree:] Download/install the
+  documentation and source files included in most packages.  Unchecking
+  is not recommended.
+
+\item[create symlinks in standard directories:]
+  This option (Unix only) bypasses the need to change environment
+  variables. Without this option, \TL{} directories usually have to be
+  added to \envname{PATH}, \envname{MANPATH} and \envname{INFOPATH}. You
+  will need write permissions to the target directories.  This option is
+  intended for accessing the \TeX\ system through directories that are
+  already known to users, such as \dirname{/usr/local/bin}, which don't
+  already contain any \TeX\ files.  Do not overwrite existing files on
+  your system with this option, e.g., by specifying system directories.
+  The safest and recommended approach is to leave the option unchecked.
+
+\item[after installation \ldots\ \CTAN:] When installing from \DVD, this
+  option is enabled by default, since usually one wants to take any
+  subsequent package updates from the \CTAN\ area that is updated
+  throughout the year.  The only likely reason to disable it is if you
+  install only a subset from the \DVD\ and plan to augment the
+  installation later.  In any case, the package repository for the
+  installer, and for updates after installation, can be set
+  independently as needed; see section~\ref{sec:location} and
+  section~\ref{sec:dvd-install-net-updates}.
+\end{description}
+Windows-specific options, as displayed in the advanced Perl/Tk
+interface:
+\begin{description}
+\item[adjust PATH setting in registry] This ensures that all
+  programs will see the \TL{} binary directory on their search path.
+
+\item[add menu shortcuts] If set, there will be a \TL{} submenu of
+  the Start menu. There is a third option `Launcher entry' besides
+  `TeX Live menu' and `No shortcuts'. This option is described in
+  section \ref{sec:sharedinstall}.
+
+\item[change file associations] The options are `Only new' (create
+  file associations, but do not overwrite existing ones), `All' and
+  `None'.
+
+\item[install \TeX{}works front end]
+\end{description}
+When all the settings are to your liking, you can type `I' in the
+text interface, or press the `Install TeX Live' button in the
+Perl/Tk \GUI, 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.
+
+\subsection{Command-line install-tl 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 most common 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})
+  compiled with XFT support; if Perl/Tk is not available,
+  installation continues in text mode.
+
+\item[-no-gui] Force using the text mode installer, even under
+  Windows.
+
+\item[-lang {\sl LL}] Specify the installer interface
+  language as a standard (usually two-letter) code.  The installer tries
+  to automatically determine the right language but if it fails, or if
+  the right language is not available, then it uses English as a
+  fallback.  Run \verb|install-tl --help| to get the list of available
+  languages.
+
+\item[-portable] Install for portable use on, e.g., a \USB{} stick.
+  Also selectable from within the text installer with the \code{V}
+  command, and from the \GUI{} installer.  See
+  section~\ref{sec:portable-tl}.
+
+\item[-profile {\sl file}] Load the installation profile \var{file} and
+  do the installation with no user interaction.  The installer always
+  writes a file \filename{texlive.profile} to the \dirname{tlpkg}
+  subdirectory of your installation.  That file can be given as the
+  argument to redo the exact same installation on a different system,
+  for example.  Alternatively, you can use a custom profile, most easily
+  created by starting from a generated one and changing values, or an
+  empty file, which will take all the defaults.
+
+\item [-repository {\sl url-or-directory}] Specify package
+  repository from which to install; see following.
+
+\htmlanchor{opt-in-place}
+\item[-in-place] (Documented only for completeness: Do not use this
+  unless you know what you are doing.) If you already have an rsync, svn,
+  or other copy of \TL{} (see
+  \url{http://tug.org/texlive/acquire-mirror.html}) then this option
+  will use what you've got, as-is, and do only the necessary
+  post-install.  Be warned that the file \filename{tlpkg/texlive.tlpdb}
+  may be overwritten; saving it is your responsibility.  Also, package
+  removal has to be done manually. This option cannot be toggled via the
+  installer interface.
+\end{ttdescription}
+
+
+\subsubsection{The \optname{-repository} option}
+\label{sec:location}
+
+The default network package repository is a \CTAN{} mirror chosen
+automatically via \url{http://mirror.ctan.org}.
+
+If you want to override that, the location value can be a url starting
+with \texttt{ftp:}, \texttt{http:}, or \texttt{file:/}, or a plain
+directory path.  (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/systems/texlive/tlnet/},
+substituting a real hostname and its particular top-level \CTAN\ path
+for |ctan.example.org/tex-archive|.  The list of \CTAN\ mirrors is
+maintained at \url{http://ctan.org/mirrors}.
+
+If the given argument is local (either a path or a \texttt{file:/} url),
+compressed files in an \dirname{archive} subdirectory of the repository
+path are used (even if uncompressed files are available as well).
+
+
+\subsection{Post-install actions}
+\label{sec:postinstall}
+
+Some post-installation may be required.
+
+\subsubsection{Environment variables for Unix}
+\label{sec:env}
+
+If you elected to create symlinks in standard directories (described in
+section~\ref{sec:options}), then there is no need to edit environment
+variables.  Otherwise, on Unix systems, the directory of the binaries
+for your platform must be added to the search path.  (On Windows, the
+installer takes care of this.)
+
+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.
+
+Optionally, you can also add the documentation man and Info directories
+to their respective search paths, if you want the system tools to find
+them.  The man pages might be found automatically after the addition to
+\envname{PATH}.
+
+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{$HOME/.profile} (or another file sourced by
+\filename{.profile}, and the lines to add would look like this:
+
+\begin{sverbatim}
+PATH=/usr/local/texlive/2017/bin/i386-linux:$PATH; export PATH
+MANPATH=/usr/local/texlive/2017/texmf-dist/doc/man:$MANPATH; export MANPATH
+INFOPATH=/usr/local/texlive/2017/texmf-dist/doc/info:$INFOPATH; export INFOPATH
+\end{sverbatim}
+
+For csh or tcsh, the file to edit is typically \filename{$HOME/.cshrc}, and
+the lines to add might look like:
+
+\begin{sverbatim}
+setenv PATH /usr/local/texlive/2017/bin/i386-linux:$PATH
+setenv MANPATH /usr/local/texlive/2017/texmf-dist/doc/man:$MANPATH
+setenv INFOPATH /usr/local/texlive/2017/texmf-dist/doc/info:$INFOPATH
+\end{sverbatim}
+
+If you already have settings somewhere in your ``dot'' files, naturally
+the \TL\ directories should 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/2017/bin/i386-linux \
+            /usr/local/texlive/2017/texmf-dist/doc/man
+\end{sverbatim}
+
+And 2)~check for a file \filename{/etc/environment} which may define the
+search path and other default environment variables.
+
+In each (Unix) binary directory, we also create a symbolic link named
+\code{man} to the directory \dirname{texmf-dist/doc/man}.  Some \code{man}
+programs, such as the standard \MacOSX\ \code{man}, will automatically
+find that, obviating the need for any man page setup.
+
+
+\subsubsection{Internet updates after \DVD\ installation}
+\label{sec:dvd-install-net-updates}
+
+If you installed \TL\ from \DVD\ and then wish to get updates from the
+Internet, you need to run this command---\emph{after} you've updated
+your search path (as described in the previous section):
+
+\begin{alltt}
+> \Ucom{tlmgr option repository http://mirror.ctan.org/systems/texlive/tlnet}
+\end{alltt}
+
+This tells \cmdname{tlmgr} to use a nearby \CTAN\ mirror for future updates.
+This is done by default when installing from \DVD, via the option
+described in section~\ref{sec:options}.
+
+If there are problems with the automatic mirror selection, you can
+specify a particular \CTAN\ mirror from the list at
+\url{http://ctan.org/mirrors}.  Use the exact path to the
+\dirname{tlnet} subdir on that mirror, as shown above.
+
+
+\htmlanchor{xetexfontconfig}  % keep historical anchor working
+\htmlanchor{sysfontconfig}
+\subsubsection{System font configuration for \protect\XeTeX\protect\ and Lua\protect\TeX}
+\label{sec:font-conf-sys}
+
+\XeTeX\ and Lua\TeX\ can use any font installed on the system, not just
+those in the \TeX\ trees.  They do these via related but not identical
+methods.
+
+On Windows, fonts shipped with \TL\ are automatically made available to
+\XeTeX\ by font name.  On \MacOSX, supporting font name lookups requires
+additional steps; please see the Mac\TeX\ web pages
+(\url{http://tug.org/mactex}).  For other Unix systems, the procedure to
+be able to find the fonts shipped with \TL\ via font name follows.
+
+To facilitate this, when the \pkgname{xetex} package is installed
+(either at initial installation or later), the necessary configuration
+file is created in
+\filename{TEXMFSYSVAR/fonts/conf/texlive-fontconfig.conf}.
+
+To set up the \TL{} fonts for system-wide use (assuming you have
+suitable privileges), proceed as follows:
+\begin{enumerate*}
+\item Copy the \filename{texlive-fontconfig.conf} file to
+\dirname{/etc/fonts/conf.d/09-texlive.conf}.
+\item Run \Ucom{fc-cache -fsv}.
+\end{enumerate*}
+
+If you do not have sufficient privileges to carry out the steps above,
+or if you want to make the \TL{} fonts available to only one user,
+you can do the following:
+\begin{enumerate*}
+\item Copy the \filename{texlive-fontconfig.conf} file to
+      \filename{~/.fonts.conf}, where \filename{~} is your home directory.
+\item Run \Ucom{fc-cache -fv}.
+\end{enumerate*}
+
+You can run \code{fc-list} to see the names of the system fonts.  The
+incantation \code{fc-list : family style file spacing} (all arguments
+are literal strings) shows some generally interesting information.
+
+
+\subsubsection{\protect\ConTeXt{} Mark IV}
+\label{sec:context-mkiv}
+
+Both the `old' \ConTeXt{} (Mark II) and the `new' \ConTeXt{}
+(Mark IV) should run out of the box after \TL{} installation,
+and should need no special attention as long as you stick to
+using \verb+tlmgr+ for updates.
+
+However, because \ConTeXt{} MkIV does not use the kpathsea
+library, some setup will be required whenever you install new 
+files manually (without using \verb+tlmgr+). After each such 
+installation, each MkIV user must run:
+\begin{sverbatim}
+context --generate
+\end{sverbatim}
+to refresh the \ConTeXt{} disk cache data.
+The resulting files are stored under \code{TEXMFCACHE},
+whose default value in \TL\ is \verb+TEXMFSYSVAR;TEXMFVAR+. 
+
+\ConTeXt\ MkIV will read from
+all paths mentioned in \verb+TEXMFCACHE+, and write to the first
+path that is writable. While reading, the last found match will 
+take precedence in the case of duplicated cache data.
+
+For more information, 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|%SystemDrive%\texlive\texmf-local| on Windows)
+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 \TeX\ Directory
+Structure (\TDS) subdirectories; see \url{http://tug.org/tds} or consult
+\filename{texmf-dist/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 the \TeX\ Live Manager \GUI.
+
+By default, each of these variables is defined to be a single directory,
+as shown.  This is not a hard-and-fast requirement.  If you need to
+easily switch back and forth between different versions of large
+packages, for example, you can maintain multiple trees for your own
+purposes.  This is done by setting \dirname{TEXMFHOME} to the
+list of directories, within braces, separated by commas:
+
+\begin{verbatim}
+  TEXMFHOME = {/my/dir1,/mydir2,/a/third/dir}
+\end{verbatim}
+
+Section~\ref{sec:brace-expansion} describes brace expansion further.
+
+
+\subsubsection{Integrating third-party fonts}
+
+This is unfortunately a messy topic.  Forget about it unless you want to
+delve into many details of the \TeX{} installation.  Many fonts are
+included in \TL\ already, so take a look if you don't already know 
+that what you want isn't there.
+
+A possible alternative is to use \XeTeX\ or Lua\TeX\ (see
+section~\ref{sec:tex-extensions}), which let you use operating system
+fonts without any installation in \TeX.
+
+If you do need to do this, see
+\url{http://tug.org/fonts/fontinstall.html} for our best effort at
+describing the procedure.
+
+
+\subsection{Testing the installation}
+\label{sec:test-install}
+
+After installing \TL{}, you naturally want to test it out, so you can
+start creating beautiful documents and\slash or fonts.
+
+One thing you may immediately be looking for is a front-end with which
+to edit files.  \TL{} installs \TeX{}works
+(\url{http://tug.org/texworks}) on Windows (only), and Mac\TeX\ installs
+TeXShop (\url{http://pages.uoregon.edu/koch/texshop}.  On other Unix
+systems, it's left up to you to choose an editor.  There are many
+choices available, some of which are listed in the next section; see
+also \url{http://tug.org/interest.html#editors}.  Any plain text editor
+will work; something \TeX-specific is not required.
+
+The rest of 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 3.14159265 (TeX Live ...)
+Copyright ... D.E. Knuth.
+...
+\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 pdfTeX 3.14...
+...
+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}    # Unix
+> \Ucom{dviout sample2e.dvi}  # Windows
+\end{alltt}
+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
+\TeX.)  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 PDF file instead of \dvi{}; this processes the
+\filename{.tex} file and writes PDF directly:
+\begin{alltt}
+> \Ucom{pdflatex sample2e.tex}
+\end{alltt}
+
+\item Preview the PDF file:
+\begin{alltt}
+> \Ucom{gv sample2e.pdf}
+\textrm{or:}
+> \Ucom{xpdf sample2e.pdf}
+\end{alltt}
+Neither \cmdname{gv} nor \cmdname{xpdf} are 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 PDF viewers, too.  For Windows, we recommend trying Sumatra
+PDF (\url{https://www.sumatrapdfreader.org/free-pdf-reader.html}).
+
+\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}
+
+\item If you have installed the \filename{xetex} package, you can test
+its access to system fonts as follows:
+\begin{alltt}
+> \Ucom{xetex opentype-info.tex}
+This is XeTeX, Version 3.14\dots
+...
+Output written on opentype-info.pdf (1 page).
+Transcript written on opentype-info.log.
+\end{alltt}
+
+If you get an error message saying ``Invalid fontname `Latin Modern
+Roman/ICU'\dots'', then you need to configure your system so that the
+fonts shipped with \TL\ can be found.  See
+Section~\ref{sec:font-conf-sys}.
+
+\end{enumerate}

+
+
+\section{Specialized installations}
+
+The previous sections described the basic installation process.  Here we
+turn to some specialized cases.
+
+\htmlanchor{tlsharedinstall}
+\subsection{Shared-user (or cross-machine) installations}
+\label{sec:sharedinstall}
+
+\TL{} has been designed to be shared between different systems on a
+network. With a standard directory layout, no hard paths are
+configured: the locations for files needed by \TL{} programs are
+found relative to the programs.  You can see this in the principal
+configuration file
+\filename{$TEXMFDIST/web2c/texmf.cnf}, which contains lines such as
+\begin{sverbatim}
+TEXMFROOT = $SELFAUTOPARENT
+...
+TEXMFDIST = $TEXMFROOT/texmf-dist
+...
+TEXMFLOCAL = $SELFAUTOGRANDPARENT/texmf-local
+\end{sverbatim}
+This means that adding the directory for \TL{} executables for their
+platform to their search path is sufficient to get a working setup.
+
+By the same token, you can also install \TL{} locally and then move
+the entire hierarchy afterwards to a network location.
+
+For Windows, \TL{} includes a launcher \filename{tlaunch}. Its main
+window contains menu entries and buttons for various \TeX-related
+programs and documentation, customizable via an \code{ini} file.  On
+first use, it replicates the usual Windows-specific post-install,
+\emph{i.e.}, search path modification and file associations, but only
+for the current user. Therefore, workstations with access to \TL{} on
+the local network only need a menu shortcut for the launcher.  See the
+\code{tlaunch} manual (\code{texdoc tlaunch}, or
+\url{https://ctan.org/pkg/tlaunch}).
+
+
+\htmlanchor{tlportable}
+\subsection{Portable (\USB{}) installations}
+\label{sec:portable-tl}
+
+The \code{-portable} installer option (or \code{V} command in the text
+installer or corresponding \GUI{} option) creates a completely
+self-contained \TL{} installation under a common root and forgoes system
+integration. You can create such an installation directly on a \USB{}
+stick, or copy it to a \USB{} stick afterwards.
+
+To run \TeX\ using this portable installation, you need to add the
+appropriate binary directory to the search path during your terminal
+session, as usual.
+
+On Windows, you can double-click \filename{tl-tray-menu} at the root
+of the installation and create a temporary `tray menu' offering a
+choice of a few common tasks, as shown in this screenshot:
+
+\medskip
+\tlpng{tray-menu}{4cm}
+\smallskip
+
+\noindent The `More\ldots' entry explains how you can customize this menu.
+
+
+%\htmlanchor{tlisoinstall}
+%\subsection{\ISO\ (or \DVD) installations}
+%\label{sec:isoinstall}
+%
+%If you don't need to update or otherwise modify your installation often,
+%and\slash or have several systems on which to use \TL{}, it may be
+%convenient to create an \ISO\ of your \TL{} installation, because:
+%
+%\begin{itemize}
+%\item Copying an \ISO\ between different computers is much
+%  faster than copying a normal installation.
+%\item If you are dual-booting between different operating systems
+%  and want them to share a \TL{} installation, an \ISO
+%  installation is not tied to the idiosyncrasies and limitations of
+%  other mutually supported filesystems (FAT32, NTFS,
+%  HFS+).
+%\item Virtual machines can simply mount such an \ISO.
+%\end{itemize}
+%
+%Of course you can also burn an \ISO\ to \DVD, if that is useful for you.
+%
+%Desktop \GNU/Linux/Unix systems, including \MacOSX, are able to
+%mount an \ISO. Windows 8 is the first(!) Windows version which can
+%do this. Apart from that, nothing changes compared to a normal hard
+%disk installation, see section \ref{sec:env}.
+%
+%When preparing such an \ISO\ installation, it is best to omit the
+%subdirectory for the release year, and have
+%\filename{texmf-local} at the same level as the other trees
+%(\filename{texmf-dist}, \filename{texmf-var}, etc.).  You can do this with
+%the normal directory options in the installer.
+%
+%For a physical (rather than virtual) Windows system, you can burn
+%the \ISO\ to DVD. However, it may be worth your while to
+%investigate free \ISO-mounting options such as WinCDEmu at
+%\url{http://wincdemu.sysprogs.org/}.
+%
+%For Windows system integration, you can include the \filename{w32client}
+%scripts described in section~\ref{sec:sharedinstall} and at
+%\url{http://tug.org/texlive/w32client.html}, which work just as well for
+%an \ISO\ as for a network installation.
+%
+%On \MacOSX, TeXShop will be able to use the DVD
+%installation if a symlink \filename{/usr/texbin} points to the
+%appropriate binary directory, e.g.,
+%\begin{verbatim}
+%sudo ln -s /Volumes/MyTeXLive/bin/universal-darwin /usr/texbin
+%\end{verbatim}
+%
+%Historical note: \TL{} 2010 was the first \TL{} edition which was no
+%longer distributed `live'.  However, it always required some acrobatics
+%to run from \DVD\ or \ISO; in particular, there was no way around
+%setting at least one extra environment variable.  If you create your
+%\ISO\ from an existing installation then there is no need for this.
+
+

+\section{\cmdname{tlmgr}: Managing your installation}
+\label{sec:tlmgr}

+    \label{fig:tlmgr-paper-options}
+  }
+}
+\end{figure}
+
+\TL{} includes a program named \prog{tlmgr} for managing \TL{} after the
+initial installation.  Its capabilities include:
+
+\begin{itemize*}
+\item installing, updating, backing up, restoring, and uninstalling
+  individual packages, optionally taking dependencies into account;
+\item searching for and listing packages and their descriptions;
+\item listing, adding, and removing platforms;
+\item changing installation options such as paper size and source
+  location (see section~\ref{sec:location}).
+\end{itemize*}
+
+\prog{tlmgr}'s functionality completely subsumes the \prog{texconfig}
+program.  We still distribute and maintain \prog{texconfig} for the sake
+of anyone used to its interface, but we recommend using \prog{tlmgr}
+nowadays.
+
+\subsection{\cmdname{tlmgr} \GUI{} mode}
+\prog{tlmgr} can be started in \GUI{} mode (figure~\ref{fig:tlmgr-gui}) with
+\begin{alltt}
+> \Ucom{tlmgr -gui}
+\end{alltt}
+or in Windows via the Start menu: \texttt{Start}, \texttt{Programs},
+\texttt{TeX Live ...}, \texttt{TeX Live Manager}. After clicking `Load'
+it displays a list of available and installed packages.  This assumes of
+course that the installation source is valid and reachable.
+
+Figures~\ref{fig:tlmgr-general-options} and~\ref{fig:tlmgr-paper-options}
+show the general and paper size option screens.
+
+\subsection{Sample \cmdname{tlmgr} command-line invocations}
+
+After the initial installation, you can update your system to the latest
+versions available with:
+\begin{alltt}
+> \Ucom{tlmgr update -all}
+\end{alltt}
+If this makes you nervous, first try
+\begin{alltt}
+> \Ucom{tlmgr update -all -dry-run}
+\end{alltt}
+or (less verbose):
+\begin{alltt}
+> \Ucom{tlmgr update -list}
+\end{alltt}
+
+This more complex example adds a collection, for the engine \XeTeX, from
+a local directory:
+
+\begin{alltt}
+> \Ucom{tlmgr -repository /local/mirror/tlnet install collection-xetex}
+\end{alltt}
+It generates the following output (abridged):
+\begin{fverbatim}
+install: collection-xetex
+install: arabxetex
+...
+install: xetex
+install: xetexconfig
+install: xetex.i386-linux
+running post install action for xetex
+install: xetex-def
+...
+running mktexlsr
+mktexlsr: Updating /usr/local/texlive/2017/texmf-dist/ls-R...
+...
+running fmtutil-sys --missing
+...
+Transcript written on xelatex.log.
+fmtutil: /usr/local/texlive/2017/texmf-var/web2c/xetex/xelatex.fmt installed.
+\end{fverbatim}
+
+As you can see, \prog{tlmgr} installs dependencies, and takes care of any
+necessary post-install actions, including updating the filename database
+and (re)generating formats.  In the above, we generated new formats for
+\XeTeX.
+
+To describe a package (or collection or scheme):
+\begin{alltt}
+> \Ucom{tlmgr show collection-latexextra}
+\end{alltt}
+which produces output like this:
+\begin{fverbatim}
+package:    collection-latexextra
+category:   Collection
+shortdesc:  LaTeX supplementary packages
+longdesc:   A very large collection of add-on packages for LaTeX.
+installed:  Yes
+revision:   32768
+\end{fverbatim}

+\section{Notes on Windows}
+\label{sec:windows}
+
+\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 (\prog{psv})
+  PostScript previewer) and some documentation.
+\item[File associations.] If enabled, \prog{TeXworks}, \prog{Dviout}
+  and \prog{PS\_view} become either the default program for
+  their respective filetypes, or get an entry in the `Open with'
+  right-click menus of those filetypes.
+\item[Bitmap to eps converter.] Various bitmapped formats get an
+  entry \cmdname{bitmap2eps} in their `Open with' right-click
+  menu. Bitmap2eps is a simple script which lets \cmdname{sam2p} or
+  \cmdname{bmeps} do the real work.
+\item[Automatic path adjustment.] No manual configuration steps are required.
+\item[Uninstaller.] The installer creates an entry under `Add/Remove
+  Programs' for \TL. The uninstall tab of the \TeX\ Live Manager \GUI\
+  refers to this. For a single-user install, the installer also
+  creates an uninstall entry under the Start menu.
+\item[Write-protect.] For an admin install, the \TL\ directories are
+  write-protected, at least if \TL\ is installed on a normal
+  NTFS-formatted non-removable disk.
+\end{description}
+
+Also, have a look at \filename{tlaunch}, described in
+section~\ref{sec:sharedinstall}, for a different approach.
+
+\subsection{Additional software included on Windows}
+
+To be complete, a \TL{} installation needs support packages that are not
+commonly found on a Windows machine. \TL{} provides the missing pieces.
+These programs are all installed as part of \TL{} only on Windows.
+
+\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 installations, and
+  shouldn't interfere with any system installations of Perl or
+  Ghostscript.
+
+\item[PS\_View.] Also installed is PS\_View, a \PS{} and PDF
+  viewer; see figure~\ref{fig:psview}.
+
+\begin{figure}[tb]
+\tlpng{psview}{.6\linewidth}
+\caption{PS\_View: very high magnifications available!}\label{fig:psview}
+\end{figure}
+
+\item[dviout.] Also installed is \prog{dviout}, a DVI viewer.
+  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
+  (highly recommended) on-line help.
+
+\item[\TeX{}works.]  \TeX{}works is a \TeX-oriented editor with
+  an integrated PDF viewer.
+
+\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{unzip} and the
+  utilities from the \cmdname{xpdf} suite (\cmdname{pdfinfo},
+  \cmdname{pdffonts}, \ldots).  The \cmdname{xpdf} viewer itself is
+  not available for Windows. Instead, you can download the Sumatra
+  PDF viewer, which is based on \cmdname{xpdf}, from
+  \url{https://www.sumatrapdfreader.org/free-pdf-reader.html}, among
+  other options.
+
+\item[fc-list, fc-cache, \ldots] The tools from the fontconfig library allow
+  \XeTeX{} to handle system fonts on Windows.  You can use
+  \prog{fc-list} to determine the font names to pass to \XeTeX's
+  extended \cs{font} command. If necessary, run \prog{fc-cache}
+  first to update font information.
+
+\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 Vista and later it is
+\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. We have made an effort to make \TL{}
+installable without administrative privileges.
+
+If the installer is started with administrative permissions, there is an
+option to install for all users.  If this option is chosen, 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.
+
+Regardless of administrator status, the default root of \TL{} proposed
+by the installer is always under \verb|%SystemDrive%|. 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{}
+would never get precedence.  As a safeguard, the installer creates a
+shortcut to the command-prompt in which the new \TL{} binary
+directory is prepended to the local search path.  The new \TL{} will
+be always usable from within such a command-prompt. The shortcut for
+\TeX{}works, if installed, also prepends \TL{} to the search path, so it
+should also be immune to this path problem.
+
+For Windows Vista and later, you should be aware that even if you are
+logged in as administrator, you need to explicitly ask for administrator
+privileges. In fact, there is not much point in logging in as
+administrator. Instead, right-clicking on the program or shortcut that
+you want to run usually gives you a choice `Run as administrator'.
+
+
+\subsection{Increasing maximum memory on Windows and Cygwin}
+\label{sec:cygwin-maxmem}
+
+Windows and Cygwin (see section~\ref{sec:cygwin} for Cygwin installation
+specifics) users may find that they run out of memory when running some
+of the programs shipped with \TL.  For example, \prog{asy} might run out
+of memory if you try to allocate an array of 25,000,000 reals, and
+Lua\TeX\ might run out of memory if you try to process a document with a
+lot of big fonts.
+
+For Cygwin, you can increase the amount of available memory by following
+the instructions in the Cygwin User's Guide
+(\url{http://www.cygwin.com/cygwin-ug-net/setup-maxmem.html}).
+
+For Windows, you have to create a file, say \code{moremem.reg}, with
+these four lines:
+
+\begin{sverbatim}
+Windows Registry Editor Version 5.00
+
+[HKEY_LOCAL_MACHINE\Software\Cygwin]
+"heap_chunk_in_mb"=dword:ffffff00
+\end{sverbatim}
+
+\noindent and then execute the command \code{regedit /s moremem.reg} as
+administrator.  (If you want to change memory only for the current user
+instead of system-wide, use \code{HKEY\_CURRENT\_USER}.)

+\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[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[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 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.
+
+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.
+

+  \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}
+
+\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}, but we do not recommend
+setting this (or any) environment variable.
+
+Instead, normal installation results in a file
+\file{.../2017/texmf.cnf}.  If you must make changes to the defaults
+(not normally necessary), this is the place to put them.  The main
+configuration file is in \file{.../2017/texmf-dist/web2c/texmf.cnf}.
+You should not edit this latter file, as your changes will be lost when
+the distributed version is updated.
+
+\emph{All} \file{texmf.cnf} files in the search path will be read and
+definitions in earlier files override those in later files.  For
+example, with a search path of \verb|.:$TEXMF|, values from
+\file{./texmf.cnf} override those from \verb|$TEXMF/texmf.cnf|.
+
+\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, 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}
+
+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
+
+\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}
+\label{sec: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}, a definition like this
+(simplified for this example) is made:
+\begin{verbatim}
+  TEXMF = {$TEXMFVAR,$TEXMFHOME,!!$TEXMFLOCAL,!!$TEXMFDIST}
+\end{verbatim}
+We can then use this to define, for example, the \TeX\ input path:
+\begin{verbatim}
+  TEXINPUTS = .;$TEXMF/tex//
+\end{verbatim}
+%$
+which means that, after looking in the current directory, the
+\code{\$TEXMFVAR/tex}, \code{\$TEXMFHOME/tex}, \code{\$TEXMFLOCAL/tex}
+and \code{\$TEXMFDIST/tex} trees \emph{only}) will be searched (the
+last two 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 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).  \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 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 the \cmdname{dvips}
+reference manual).
+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}
+\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 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 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 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.

+\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 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 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, thanks to Fabrice Popineau.
+
+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 OSF was removed
+      (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-dist/doc/generic/tds/tds.html\#Extensions}
+{\texttt{texmf-dist/doc/generic/tds/tds.html\#Extensions}}.
+
+\item Helper scripts (not meant to be invoked by users) are now located
+in a new \dirname{scripts} subdirectory of \dirname{texmf*} trees, and
+can be 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-dist/doc/generic/tds/tds.html\#Scripts}
+{\texttt{texmf-dist/doc/generic/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-dist/doc/web2c/web2c.html\#TCX-files}
+{\texttt{texmf-dist/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 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 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
+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-dist/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 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
+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 DVI to
+PNG image files, is included.  See
+\url{http://www.ctan.org/pkg/dvipng}.
+
+\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 CTAN
+(\url{http://mirror.ctan.org/tex-archive/fonts/greek/cbfonts}).
+
+\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 BSD Ports system is available, and
+GNU/Linux and FreeBSD 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 MIPSpro 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 CTAN
+(\url{http://mirror.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
+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.
+
+\subsubsection{2008}
+
+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}.
+
+\subsubsection{2009}
+
+In 2009, the default output format for Lua\AllTeX\ is now PDF, to take
+advantage of Lua\TeX's OpenType support, et al.  New executables named
+\code{dviluatex} and \code{dvilualatex} run Lua\TeX\ with DVI output.
+The Lua\TeX\ home page is \url{http://luatex.org}.
+
+The original Omega engine and Lambda format have been excised, after
+discussions with the Omega authors.  The updated Aleph and Lamed remain,
+as do the Omega utilities.
+
+A new release of the AMS \TypeI\ fonts is included, including Computer
+Modern: a few shape changes made over the years by Knuth in the Metafont
+sources have been integrated, and the hinting has been updated.  The
+Euler fonts have been thoroughly reshaped by Hermann Zapf (see
+\url{http://tug.org/TUGboat/Articles/tb29-2/tb92hagen-euler.pdf}).  In
+all cases, the metrics remain unchanged.  The AMS fonts home page is
+\url{http://www.ams.org/tex/amsfonts.html}.
+
+The new \GUI{} front end \TeX{}works is included for Windows, and also in
+Mac\TeX.  For other platforms, and more information, see the \TeX{}works
+home page, \url{http://tug.org/texworks}.  It is a cross-platform front
+end inspired by the \MacOSX\ TeXShop editor, aiming at ease-of-use.
+
+The graphics program Asymptote is included for several platforms.  This
+implements a text-based graphics description language vaguely akin to
+MetaPost, but with advanced 3D support and other features.  Its home
+page is \url{http://asymptote.sourceforge.net}.
+
+The separate \code{dvipdfm} program has been replaced by
+\code{dvipdfmx}, which operates in a special compatibility mode under
+that name.  \code{dvipdfmx} includes CJK support and has
+accumulated many other fixes over the years since the last
+\code{dvipdfm} release.
+
+Executables for the \pkgname{cygwin} and \pkgname{i386-netbsd} platforms
+are now included, while we were advised that OpenBSD users get
+\TeX\ through their package systems, plus there were difficulties in
+making binaries that have a chance of working on more than one version.
+
+A miscellany of smaller changes: we now use \pkgname{xz} compression,
+the stable replacement for \pkgname{lzma}
+(\url{http://tukaani.org/xz/}); a literal |$| is allowed in filenames
+when it does not introduce a known variable name; the Kpathsea library
+is now multi-threaded (made use of in MetaPost); the entire \TL{} build
+is now based on Automake.
+
+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}.
+
+
+\subsubsection{2010}
+\label{sec:2010news} % keep with 2010
+
+In 2010, the default version for PDF output is now 1.5, enabling more
+compression.  This applies to all the \TeX\ engines when used to produce
+PDF and to \code{dvipdfmx}.  Loading the \pkgname{pdf14} \LaTeX\ package
+changes back to PDF~1.4, or set |\pdfminorversion=4|.
+
+pdf\AllTeX\ now \emph{automatically} converts a requested Encapsulated
+PostScript (EPS) file to PDF, via the \pkgname{epstopdf} package, when
+and if the \LaTeX\ \code{graphics.cfg} configuration file is loaded, and
+PDF is being output.  The default options are intended to eliminate any
+chance of hand-created PDF files being overwritten, but you can also
+prevent \code{epstopdf} from being loaded at all by putting
+|\newcommand{\DoNotLoadEpstopdf}{}| (or |\def...|) before the
+\cs{documentclass} declaration.  It is also not loaded if the
+\pkgname{pst-pdf} package is used.  For more details, see the
+\pkgname{epstopdf} package documentation
+(\url{http://ctan.org/pkg/epstopdf-pkg}).
+
+A related change is that execution of a very few external commands from
+\TeX, via the \cs{write18} feature, is now enabled by default.  These
+commands are \code{repstopdf}, \code{makeindex}, \code{kpsewhich},
+\code{bibtex}, and \code{bibtex8}; the list is defined in
+\code{texmf.cnf}.  Environments which must disallow all such external
+commands can deselect this option in the installer (see
+section~\ref{sec:options}), or override the value after installation by
+running |tlmgr conf texmf shell_escape 0|.
+
+Yet another related change is that \BibTeX\ and Makeindex now refuse to
+write their output files to an arbitrary directory (like \TeX\ itself),
+by default.  This is so they can now be enabled for use by the
+restricted \cs{write18}.  To change this, the \envname{TEXMFOUTPUT}
+environment variable can be set, or the |openout_any| setting changed.
+
+\XeTeX\ now supports margin kerning along the same lines as pdf\TeX.
+(Font expansion is not presently supported.)
+
+By default, \prog{tlmgr} now saves one backup of each package updated
+(\code{tlmgr option autobackup 1}), so broken package updates can be
+easily reverted with \code{tlmgr restore}.  If you do post-install
+updates, and don't have the disk space for the backups, run \code{tlmgr
+option autobackup 0}.
+
+New programs included: the p\TeX\ engine and related utilities for
+typesetting Japanese; the \BibTeX{}U program for Unicode-enabled
+\BibTeX; the \prog{chktex} utility
+(\url{http://baruch.ev-en.org/proj/chktex}) for checking \AllTeX\
+documents; the \prog{dvisvgm} (\url{http://dvisvgm.sourceforge.net})
+DVI-to-SVG translator.
+
+Executables for these new platforms are now included: \code{amd64-freebsd},
+\code{amd64-kfreebsd}, \code{i386-freebsd}, \code{i386-kfreebsd},
+\code{x86\_64-darwin}, \code{x86\_64-solaris}.
+
+A change in \TL{} 2009 that we failed to note: numerous \TeX4ht-related
+executables (\url{http://tug.org/tex4ht}) were removed from the binary
+directories.  The generic \code{mk4ht} program can be used to run any of
+the various \code{tex4ht} combinations.
+
+Finally, the \TL{} release on the \TK\ \DVD\ can no longer be run live
+(oddly enough).  A single \DVD\ no longer has enough room.  One
+beneficial side effect is that installation from the physical \DVD\ is
+much faster.
+
+\subsubsection{2011}
+
+The \MacOSX\ binaries (\code{universal-darwin} and
+\code{x86\_64-darwin}) now work only on Leopard or later; Panther and
+Tiger are no longer supported.
+
+The \code{biber} program for bibliography processing is included on
+common platforms.  Its development is closely coupled with the
+\code{biblatex} package, which completely reimplements the
+bibliographical facilities provided by LaTeX.
+
+The MetaPost (\code{mpost}) program no longer creates or uses
+\code{.mem} files.  The needed files, such as \code{plain.mp}, are
+simply read on every run.  This is related to supporting MetaPost as a
+library, which is another significant though not user-visible change.
+
+The \code{updmap} implementation in Perl, previously used only on
+Windows, has been revamped and is now used on all platforms.  There
+shouldn't be any user-visible changes as a result, except that it runs
+much faster.
+
+The \cmdname{initex} and \cmdname{inimf} programs were restored (but no
+other \cmdname{ini*} variants).
+
+\subsubsection{2012}
+
+\code{tlmgr} supports updates from multiple network repositories.  The
+section on multiple repositories in the \code{tlmgr help} output has
+more.
+
+The parameter \cs{XeTeXdashbreakstate} is set to~1 by default, for both
+\code{xetex} and \code{xelatex}.  This allows line breaks after
+em-dashes and en-dashes, which has always been the behavior of plain
+\TeX, \LaTeX, Lua\TeX, etc.  Existing \XeTeX\ documents which must
+retain perfect line-break compatibility will need to set
+\cs{XeTeXdashbreakstate} to~0 explicitly.
+
+The output files generated by \code{pdftex} and \code{dvips}, among
+others, can now exceed 2 gigabytes.
+
+The 35 standard PostScript fonts are included in the output of
+\code{dvips} by default, since so many different versions of them are
+extant.
+
+In the restricted \cs{write18} execution mode, set by default,
+\code{mpost} is now an allowed program.
+
+A \code{texmf.cnf} file is also found in \filename{../texmf-local},
+e.g., \filename{/usr/local/texlive/texmf-local/web2c/texmf.cnf}, if it
+exists.
+
+The \code{updmap} script reads a per-tree \code{updmap.cfg} instead of
+one global config.  This change should be invisible, unless you edited
+your updmap.cfg's directly.  The \verb|updmap --help| output has more.
+
+Platforms: \pkgname{armel-linux} and \pkgname{mipsel-linux} added;
+\pkgname{sparc-linux} and \pkgname{i386-netbsd} are no longer in the
+main distribution.
+
+\subsubsection{2013}
+
+Distribution layout: the top-level \code{texmf/} directory has been
+merged into \code{texmf-dist/}, for simplicity.  Both the
+\code{TEXMFMAIN} and \code{TEXMFDIST} Kpathsea variables now point to
+\code{texmf-dist}.
+
+Many small language collections have been merged together, to simplify
+installation.
+
+\MP: native support for PNG output and floating-point (IEEE double) has
+been added.
+
+Lua\TeX: updated to Lua 5.2, and includes a new library
+(\code{pdfscanner}) to process external PDF page content, among much
+else (see its web pages).
+
+\XeTeX\ (also see its web pages for more):
+\begin{itemize*}
+\item The HarfBuzz library is now used for font layout instead of
+ICU.  (ICU is still used to support input encodings, bidirectionality,
+and the optional Unicode line breaking.)
+\item Graphite2 and HarfBuzz are used instead of SilGraphite for Graphite
+layout.
+\item On Macs, Core Text is used instead of the (deprecated) ATSUI.
+\item Prefer TrueType/OpenType fonts to Type1 when the names are the same.
+\item Fix occasional mismatch in font finding between \XeTeX\ and
+\code{xdvipdfmx}.
+\item Support OpenType math cut-ins.
+\end{itemize*}
+
+\cmdname{xdvi}: now uses FreeType instead of \code{t1lib} for rendering.
+
+\pkgname{microtype.sty}: some support for \XeTeX\ (protrusion) and
+Lua\TeX\ (protrusion, font expansion, tracking), among other
+enhancements.
+
+\cmdname{tlmgr}: new \code{pinning} action to ease configuring multiple
+repositories; that section in \verb|tlmgr --help| has more, online at
+\url{http://tug.org/texlive/doc/tlmgr.html#MULTIPLE-REPOSITORIES}.
+
+Platforms: \pkgname{armhf-linux}, \pkgname{mips-irix},
+\pkgname{i386-netbsd}, and \pkgname{amd64-netbsd} added or revived;
+\pkgname{powerpc-aix} removed.
+
+\subsubsection{2014}
+
+2014 saw another \TeX\ tune-up from Knuth; this affected all engines,
+but the only visible change likely is the restoration of the
+\code{preloaded format} string on the banner line.  Per Knuth, this now
+reflects the format that \emph{would} be loaded by default, rather than
+an undumped format that is actually preloaded in the binary; it may be
+overridden in various ways.
+
+pdf\TeX: new warning-suppression parameter
+\cs{pdfsuppresswarningpagegroup}; new primitives for fake interword
+spaces to help with PDF text reflowing: \cs{pdfinterwordspaceon},
+\cs{pdfinterwordspaceoff}, \cs{pdffakespace}.
+
+Lua\TeX: Notable changes and fixes were made to font loading and
+hyphenation.  The biggest addition is a new engine variant,
+\code{luajittex} (\url{http://foundry.supelec.fr/projects/luajittex})
+and its siblings \code{texluajit} and \code{texluajitc}.  This uses a
+just-in-time Lua compiler (detailed \textsl{TUGboat} article at
+\url{http://tug.org/TUGboat/tb34-1/tb106scarso.pdf}).  \code{luajittex}
+is still in development, is not available on all platforms, and is
+considerably less stable than \code{luatex}.  Neither we nor its
+developers recommend using it except for the specific purpose of
+experimenting with jit on Lua code.
+
+\XeTeX: The same image formats are now supported on all platforms
+(including Mac); avoid Unicode compatibility decomposition fallback (but
+not other variants); prefer OpenType to Graphite fonts, for
+compatibility with previous \XeTeX\ versions.
+
+\MP: A new numbersystem \code{decimal} is supported, along with a
+companion internal \code{numberprecision}; a new definition of
+\code{drawdot} in \filename{plain.mp}, per Knuth; bug fixes in
+SVG and PNG output, among others.
+
+The \cmdname{pstopdf} Con\TeX{}t utility will be removed as a standalone
+command at some point after the release, due to conflicts with OS
+utilities of the same name.  It can still (and now) be invoked as
+\code{mtxrun --script pstopdf}.
+
+\cmdname{psutils} has been substantially revised by a new maintainer.
+As a result, several seldom-used utilities (\code{fix*}, \code{getafm},
+\code{psmerge}, \code{showchar}) are now only in the \dirname{scripts/}
+directory rather than being user-level executables (this can be reversed
+if it turns out to be problematic).  A new script, \code{psjoin}, has
+been added.
+
+The Mac\TeX\ redistribution of \TeX\ Live (section~\ref{sec:macosx}) no
+longer includes the optional Mac-only packages for the Latin Modern and
+\TeX\ Gyre fonts, since it is easy enough for individual users to make
+them available to the system.  The \cmdname{convert} program from
+ImageMagick has also been excised, since \TeX4ht (specifically
+\code{tex4ht.env}) now uses Ghostscript directly.
+
+The \pkgname{langcjk} collection for Chinese, Japanese, and Korean
+support has been split into individual language collections for the sake
+of more moderate sizes.
+
+Platforms: \pkgname{x86\_64-cygwin} added, \pkgname{mips-irix} removed;
+Microsoft no longer supports Windows XP, so our programs may
+start failing there at any time.
+
+\subsubsection{2015}
+
+\LaTeXe\ now incorporates, by default, changes previously included only
+by explicitly loading the \pkgname{fixltx2e} package, which is now a
+no-op.  A new \pkgname{latexrelease} package and other mechanisms allow
+for controlling what is done.  The included \LaTeX\ News \#22 and
+``\LaTeX\ changes'' documents have details.  Incidentally, the
+\pkgname{babel} and \pkgname{psnfss} packages, while core parts of
+\LaTeX, are maintained separately and are not affected by these changes
+(and should still work).
+
+Internally, \LaTeXe\ now includes Unicode-related engine configuration
+(what characters are letters, naming of primitives, etc.) which was
+previously part of \TeX\ Live.  This change is intended to be invisible
+to users; a few low-level internal control sequences have been renamed
+or removed, but the behavior should be just the same.
+
+pdf\TeX: Support JPEG Exif as well as JFIF; do not
+emit a warning if \cs{pdfinclusionerrorlevel} is negative; sync
+with \prog{xpdf}~3.04.
+
+Lua\TeX: New library \pkgname{newtokenlib} for scanning tokens; bug
+fixes in the \code{normal} random number generator and other places.
+
+\XeTeX: Image handling fixes; \prog{xdvipdfmx} binary looked for first
+as a sibling to \prog{xetex}; internal \code{XDV} opcodes changed.
+
+MetaPost: New numbersystem \code{binary}; new Japanese-enabled
+\prog{upmpost} and \prog{updvitomp} programs, analogous to
+\prog{up*tex}.
+
+Mac\TeX: Updates to the included Ghostscript package for CJK
+support.  The \TeX\ Distribution Preference Pane now works in Yosemite
+(\MacOSX~10.10).  Resource-fork font suitcases (generally without an
+extension) are no longer supported by \XeTeX; data-fork suitcases
+(\code{.dfont}) remain supported.
+
+Infrastructure: The \prog{fmtutil} script has been reimplemented to read
+\filename{fmtutil.cnf} on a per-tree basis, analogous to \prog{updmap}.
+Web2C \prog{mktex*} scripts (including \prog{mktexlsr}, \prog{mktextfm},
+\prog{mktexpk}) now prefer programs in their own directory, instead of
+always using the existing \envname{PATH}.
+
+Platforms: \pkgname{*-kfreebsd} removed, since \TeX\ Live is now easily
+available through the system platform mechanisms.
+Support for some additional platforms is available as custom binaries
+(\url{http://tug.org/texlive/custom-bin.html}).  In addition, some
+platforms are now omitted from the \DVD\ (simply to save space), but can
+be installed normally over the net.
+
+% 
+\subsubsection{2016}
+
+Lua\TeX: Sweeping changes to primitives, both renames and removals,
+along with some node structure rearrangements.  The changes are
+summarized in an article by Hans Hagen, ``Lua\TeX\ 0.90 backend changes
+for PDF and more''
+(\url{http://tug.org/TUGboat/tb37-1/tb115hagen-pdf.pdf}); for all the
+details, see the Lua\TeX\ manual,
+\OnCD{texmf-dist/doc/luatex/base/luatex.pdf}.
+
+Metafont: New highly experimental sibling programs MFlua and MFluajit,
+integrating Lua with \MF, for trial testing purposes.
+
+MetaPost: Bug fixes and internal preparations for MetaPost 2.0.
+
+\code{SOURCE\_DATE\_EPOCH} support in all engines except Lua\TeX\ (which
+will come in the next release) and original \code{tex} (intentionally
+omitted): if the environment variable \code{SOURCE\_DATE\_EPOCH} is set,
+its value is used for timestamps in the PDF output.  If
+\code{SOURCE\_DATE\_EPOCH\_TEX\_PRIMITIVES} is also set, the
+\code{SOURCE\_DATE\_EPOCH} value is used to initialize the \TeX\
+primitives \cs{year}, \cs{month}, \cs{day}, \cs{time}.  The pdf\TeX\
+manual has examples and details.
+
+pdf\TeX: new primitives \cs{pdfinfoomitdate}, \cs{pdftrailerid},
+\cs{pdfsuppressptexinfo}, to control values appearing in the output
+which normally change with each run.  These features are for PDF output
+only, not DVI.
+
+Xe\TeX: New primitives \cs{XeTeXhyphenatablelength},
+\cs{XeTeXgenerateactualtext},\\ \cs{XeTeXinterwordspaceshaping},
+\cs{mdfivesum}; character class limit increased to 4096; DVI id byte
+incremented.
+
+Other utilities:
+\begin{itemize*}
+\item \code{gregorio} is a new program, part of the \code{gregoriotex}
+package for typesetting Gregorian chant scores; it is included in
+\code{shell\_escape\_commands} by default.
+
+\item \code{upmendex} is an index creation program, mostly compatible
+with \code{makeindex}, with support for Unicode sorting, among other
+changes.
+
+\item \code{afm2tfm} now makes only accent-based height adjustments
+upward; a new option \code{-a} omits all adjustments.
+
+\item \code{ps2pk} can handle extended PK/GF fonts.
+\end{itemize*}
+
+Mac\TeX: The \TeX\ Distribution Preference Pane is gone; its
+functionality is now in TeX Live Utility; bundled GUI applications
+upgraded; new script \code{cjk-gs-integrate} to be run by users who wish
+to incorporate various CJK fonts into Ghostscript.
+
+Infrastructure: System-level \code{tlmgr} configuration file supported;
+verify package checksums; if GPG is available, verify signature of
+network updates.  These checks happen with both the installer and
+\code{tlmgr}.  (If GPG is not available, updates proceed as usual.)
+
+Platforms: \code{alpha-linux} and \code{mipsel-linux} removed.
+
+
+\htmlanchor{news}
+\subsection{Present---2017}
+\label{sec:tlcurrent}
+
+Lua\TeX: More callbacks, more typesetting control, more access to
+internals; \code{ffi} library for dynamic code loading added on some
+platforms.
+
+pdf\TeX: Environment variable |SOURCE_DATE_EPOCH_TEX_PRIMITIVES| from
+last year renamed to |FORCE_SOURCE_DATE|, with no changes in
+functionality; if the \cs{pdfpageattr} token list contains the string
+\code{/MediaBox}, omit output of the default \code{/MediaBox}.
+
+Xe\TeX: Unicode/OpenType math now based on HarfBuzz's MATH table support;
+some bug fixes.
+
+Dvips: Make the last papersize special win, for consistency with
+\code{dvipdfmx} and package expectations; the \code{-L0} option (\code{L0}
+config setting) restores the previous behavior of the first special
+winning.
+
+ep\TeX, eup\TeX: New primitives \cs{pdfuniformdeviate},
+\cs{pdfnormaldeviate}, \cs{pdfrandomseed}, \cs{pdfsetrandomseed},
+\cs{pdfelapsedtime}, \cs{pdfresettimer}, from pdf\TeX.
+
+Mac\TeX: As of this year, only \MacOSX\ releases for which Apple still
+releases security patches will be supported in Mac\TeX, under the
+platform name |x86_64-darwin|; currently this means Yosemite,
+El~Capitan, and Sierra (10.10 and newer). Binaries for older \MacOSX\
+versions are not included in Mac\TeX, but are still available in \TeX\
+Live (|x86_64-darwinlegacy|, \code{i386-darwin}, \code{powerpc-darwin}).
+
+Infrastructure: The \envname{TEXMFLOCAL} tree is now searched before
+\envname{TEXMFSYSCONFIG} and \envname{TEXMFSYSVAR} (by default); the
+hope is that this will better match expectations of local files
+overriding system files.  Also, \code{tlmgr} has a new mode \code{shell}
+for interactive and scripted use, and a new action \code{conf auxtrees}
+to easily add and remove extra trees.
+
+\code{updmap} and \code{fmtutil}: These scripts now give a warning when
+invoked without explicitly specifying either so-called system mode
+(\code{updmap-sys}, \code{fmtutil-sys}, or option \code{-sys}), or user
+mode (\code{updmap-user}, \code{fmtutil-user}, or option \code{-user}).
+The hope is that this will reduce the perennial problem of invoking user
+mode by accident and thus losing future system updates.  See
+\url{http://tug.org/texlive/scripts-sys-user.html} for details.
+
+\code{install-tl}: Personal paths are now set to Mac\TeX\ values
+(|~/Library/...|)\ by default on Macs.  New option
+\code{-init-from-profile} to start an installation with the values from
+a given profile; new command \code{P} to explicitly save a profile; new
+profile variable names (but previous ones are still accepted).
+
+Sync\TeX: the temporary file name now looks like
+\code{foo.synctex(busy)}, instead of \code{foo.synctex.gz(busy)}
+(no~\code{.gz}). Front ends and build systems that want to remove temp
+files may need adjusting.
+
+Other utilities: \code{texosquery-jre8} is a new cross-platform program
+for retrieving locale and other OS information from a \TeX\ document; it
+is included in |shell_escape_commands| by default for restricted
+shell execution. (Older JRE versions are supported by texosquery, but
+cannot be enabled in restricted mode, as they are no longer supported by
+Oracle, even for security issues.)
+
+Platforms: See Mac\TeX\ entry above; no other changes.
+
+\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 volunteers in their spare time, and so there is always more
+to do.  Please see \url{http://tug.org/texlive/contribute.html}.

 recommend checking for suspicious files in the current directory, especially executables (binaries or scripts).
