%{\tighten
%Donald Knuth's \TeX, a computerized typesetting system,
%provides nearly everything
%needed for high-quality typesetting of mathematical
%notations as well as of ordinary text.
%It is particularly notable for its flexibility, its superb hyphenation, and its
%ability to choose aesthetically satisfying line breaks.
%Because
%of its extraordinary capabilities, \TeX\ has become the leading typesetting
%system for mathematics, science, and engineering and has been adopted as
%a standard by the American Mathematical Society.  A companion program,
%^{\Metafont},
%can construct arbitrary letterforms including, in particular, any symbols that
%might be needed in mathematics.
%Both \TeX\ and \Metafont\ are widely available within the
%scientific and engineering community and have been implemented on a
%variety of computers.
%\TeX\ isn't perfect---it lacks integrated support for graphics, and
%some effects such as ^{revision bars} are very difficult to produce---%
%but these drawbacks are far outweighed by its advantages.

%\thisbook\/ is intended to serve scientists, mathematicians, and
%technical typists for whom \TeX\ is a useful tool rather than a primary
%interest, as well as computer people who have a strong interest in \TeX\
%for its own sake.  We also intend it to serve both newcomers to \TeX\
%and those who are already familiar with \TeX.  We assume that our
%readers are comfortable working with computers and that they want to get
%the information they need as quickly as possible.  Our aim is to provide
%that information clearly, concisely, and accessibly.

%{\tighten This book therefore provides a bright searchlight, a stout
%walking-stick, and detailed maps for exploring and using \TeX.  It will
%enable you to master \TeX\ at a rapid pace through inquiry and
%experiment, but it will not lead you by the hand through the entire
%\TeX\ system.  Our approach is to provide you with a handbook for \TeX\
%that makes it easy for you to retrieve whatever information you need.
%We explain both the full repertoire of \TeX\ commands and the concepts
%that underlie them.  You won't have to waste your time plowing through
%material that you neither need nor want.  \par}

%that you can get started if you haven't used \TeX\ before.  We assume
%that you have access to a \TeX\ implementation and that you know how to
%use a text editor, but we don't assume much else about your background.
%Because this book is organized for ready reference, you'll continue to
%find it useful as you become more familiar with \TeX.  If you prefer to
%start with a carefully guided tour, we recommend that you first read
%Knuth's ^{\texbook} (see \xrefpg{resources} for a citation), passing
%over the ``dangerous bend'' sections, and then return to this book for
%additional information and for reference as you start to use \TeX.  (The

%The structure of \TeX\ is really quite simple: a \TeX\ input document
%consists of ordinary text interspersed with commands that give \TeX\
%further instructions on how to typeset your document.  Things like math
%formulas contain many such commands, while expository text contains
%relatively few of them.

%The time-consuming part of learning \TeX\ is learning the commands and
%the concepts underlying their descriptions.  Thus we've devoted most of
%the book to defining and explaining the commands and the concepts.
%We've also provided examples showing \TeX\ typeset output and the
%corresponding input, hints on solving common problems, information about
%error messages, and so forth.  We've supplied extensive cross-references
%by page number and a complete index.
