This document is version 2.0 (June 2008) of an
unofficial reference manual for LaTeX, a document preparation
system.  LaTeX is a macro package for TeX.

This was originally translated from `LATEX.HLP' v1.0a in the VMS
Help Library.  The pre-translation version was written by
GeorgeD. Greenwade of Sam Houston State University.  The
LaTeX2.09 version was written by Stephen Gilmore.  The
LaTeX2e version was adapted from this by Torsten Martinsen.  Karl
Berry made further updates and additions, and gratefully acknowledges
using `Hypertext Help with LaTeX', by Sheldon Green, and the
`LaTeX Command Summary' (for LaTeX 2.09) by L.Botway
and C.Biemesderfer (published by the TeX Users Group as
`TeXniques' number 10), as reference material (text was not
directly copied).

<h2 class="chapter">1 Overview of LaTeX</h2>

<p><a name="index-overview-of-_0040LaTeX_007b_007d-4"></a><a name="index-g_t_0040LaTeX_007b_007d-overview-5"></a>
The LaTeX command typesets a file of text using the TeX program
and the LaTeX &ldquo;macro package&rdquo; for TeX.  To be more specific,
it processes an input file containing the text of a document with
interspersed commands that describe how the text should be formatted. 
It produces at least three files as output:

     <ol type=1 start=1>
<li>A main output file, which is one of:

          <ol type=1 start=1>
<li>If invoked as <samp><span class="command">latex</span></samp>, a &ldquo;Device Independent&rdquo; (<samp><span class="file">.dvi</span></samp>)
file. This contains commands that can be translated into commands for
a variety of output devices.  You can view such <samp><span class="file">.dvi</span></samp> output of
LaTeX by using a program such as <samp><span class="command">xdvi</span></samp> (display directly)
or <samp><span class="command">dvips</span></samp> (convert to PostScript).

          <li>If invoked as <samp><span class="command">pdflatex</span></samp>, a &ldquo;Portable Document Format&rdquo;
(<samp><span class="file">.pdf</span></samp>) file.  Typically, this is a self-contained file, with
all fonts and images embedded.  This can be very useful, but it does
make the output much larger than the <samp><span class="file">.dvi</span></samp> produced from the
same document.
          </ol>

     <p>There are other less-common variants of LaTeX (and TeX) as well,
which can produce HTML, XML, and other things.

     <li>A &ldquo;transcript&rdquo; or <samp><span class="file">.log</span></samp> file that contains summary information and
diagnostic messages for any errors discovered in the input file.

     <li>An &ldquo;auxiliary&rdquo; or <samp><span class="file">.aux</span></samp> file. This is used by LaTeX itself, for
things such as sectioning.
        </ol>

   <p>A LaTeX command begins with the command name, which consists of a
<code>\</code> followed by either (a)&nbsp;a string of letters or (b)&nbsp;a
single non-letter.  Arguments contained in square brackets, <code>[]</code>,
are optional while arguments contained in braces, <code>{}</code>, are
required.

   <p>LaTeX is case sensitive.  Enter all commands in lower case unless
explicitly directed to do otherwise.

A minimal input file looks like the following:

<pre class="example">     \documentclass{<var>class</var>}
     \begin{document}
     <var>your text</var>
     \end{document}
</pre>

See <a href="#Document-classes">Document classes</a>, for details of the various document classes
available locally.

   <p><a name="index-preamble_002c-defined-8"></a>You may include other LaTeX commands between the <code>\documentclass</code>
and the <code>\begin{document}</code> commands (this area is called the
<dfn>preamble</dfn>).

<p><a name="index-document-classes-9"></a><a name="index-classes-of-documents-10"></a><a name="index-g_t_005cdocumentclass-11"></a>
The class of a given document is defined with the command:

<pre class="example">     \documentclass[<var>options</var>]{<var>class</var>}
</pre>
   <p class="noindent">The <code>\documentclass</code> command must be the first command in a
LaTeX source file.

classes are available as add-ons; see <a href="#Overview">Overview</a>):

<pre class="example">     article  report  book  letter  slides
</pre>
   <!-- xx briefly describe each one -->
   <p>Standard <var>options</var> are described below.

You can specify so-called <dfn>global options</dfn> or <dfn>class options</dfn>
to the <code>\documentclass</code> command by enclosing them in square
brackets as usual.  To specify more than one <var>option</var>, separate
them with a comma:

<pre class="example">     \documentclass[<var>option1</var>,<var>option2</var>,...]{<var>class</var>}
</pre>
   <p>Here is the list of the standard class options.

<h3 class="section">4.1 Font styles</h3>

<p><a name="index-font-styles-54"></a><a name="index-typeface-styles-55"></a><a name="index-styles-of-text-56"></a>
The following type style commands are supported by LaTeX.

   <p>These commands are used like <code>\textit{italic text}</code>. The
corresponding command in parenthesis is the &ldquo;declaration form&rdquo;, which
takes no arguments. The scope of the declaration form lasts until the
next type style command or the end of the current group.

   <p>The declaration forms are cumulative; i.e., you can say either
<code>\sffamily\bfseries</code> or <code>\bfseries\sffamily</code> to get bold
sans serif.

   <p>You can also use the environment form of the declaration forms; for instance,
<code>\begin{ttfamily}...\end{ttfamily}</code>.

</dl>

   <p>In addition, the command
<code>\mathversion{bold}</code>
<a name="index-g_t_005cmathversion-85"></a>can be used for switching to bold letters and symbols in
formulas. <code>\mathversion{normal}</code> restores the default.

   <p>LaTeX also provides these commands, which unconditionally switch to
the given style, that is, are <em>not</em> cumulative.  They are used
differently than the above commands, too: <code>{\</code><var>cmd</var><code> ...}</code>
instead of <code>\</code><var>cmd</var><code>{...}</code>.  These are two very different
things.

Synopsis:

<pre class="example">     \twocolumn[<var>text1col</var>]
</pre>
   <p>The <code>\twocolumn</code> declaration starts a new page and produces
two-column output. If the optional <var>text1col</var> argument is present,
it is typeset in one-column mode before the two-column typesetting
starts.

   <p>These parameters control typesetting in two-column output:

     <dl>
<dt><code>\columnsep</code><a name="index-g_t_005ccolumnsep-139"></a><dd>The distance between columns (35pt by default).

     <br><dt><code>\columnseprule</code><a name="index-g_t_005ccolumnseprule-140"></a><dd>The width of the rule between columns; the default is 0pt, so there is no rule.

     <br><dt><code>\columnwidth</code><a name="index-g_t_005ccolumnwidth-141"></a><dd>The width of the current column; this is equal to <code>\textwidth</code> in
single-column text.

   </dl>

   <p>These parameters control float behavior in two-column output:

     <dl>
<dt><code>\dbltopfraction</code><a name="index-g_t_005cdbltopfraction-142"></a><dd>Maximum fraction at the top of a two-column page that may be occupied
by floats.  Default &lsquo;<samp><span class="samp">.7</span></samp>&rsquo;, can be usefully redefined to (say)
&lsquo;<samp><span class="samp">.9</span></samp>&rsquo; to avoid going to float pages so soon.

<h2 class="chapter">6 Sectioning</h2>

<p><a name="index-sectioning-163"></a>
Sectioning commands provide the means to structure your text into units:

     <dl>
<dt><code>\part</code><a name="index-g_t_005cpart-164"></a><br><dt><code>\chapter</code><a name="index-g_t_005cchapter-165"></a><dd>(report and book class only)
<br><dt><code>\section</code><a name="index-g_t_005csection-166"></a><br><dt><code>\subsection</code><a name="index-g_t_005csubsection-167"></a><br><dt><code>\subsubsection</code><a name="index-g_t_005csubsubsection-168"></a><br><dt><code>\paragraph</code><a name="index-g_t_005cparagraph-169"></a><br><dt><code>\subparagraph</code><a name="index-g_t_005csubparagraph-170"></a><dd></dl>

   <p>All sectioning commands take the same general form, e.g.,

<pre class="example">     \chapter[<var>toctitle</var>]{<var>title</var>}
</pre>
   <p>In addition to providing the heading <var>title</var> in the main text, the
section title can appear in two other places:

     <ol type=1 start=1>
<li>The table of contents. 
<li>The running head at the top of the page.
        </ol>

   <p>You may not want the same text in these places as in the main text. 
To handle this, the sectioning commands have an optional argument
<var>toctitle</var> that, when given, specifies the text for these other
places.

   <p><a name="index-g_t_002a_002dform-of-sectioning-commands-171"></a>Also, all sectioning commands have <code>*</code>-forms that print
<var>title</var> as usual, but do not include a number and do not make an
entry in the table of contents.  For instance:

<pre class="example">     \section*{Preamble}
</pre>
   <p><a name="index-g_t_005cappendix-172"></a><a name="index-appendix_002c-creating-173"></a>The <code>\appendix</code> command changes the way following sectional units
are numbered.  The <code>\appendix</code> command itself generates no text
and does not affect the numbering of parts.  The normal use of this
command is something like

<pre class="example">     \chapter{A Chapter}
     ...
     \appendix
     \chapter{The First Appendix}
</pre>

<h2 class="chapter">7 Cross references</h2>

<p><a name="index-cross-references-174"></a>
One reason for numbering things like figures and equations is to refer

<h3 class="section">7.1 <code>\label</code></h3>

<p><a name="index-g_t_005clabel-175"></a>
Synopsis:

<pre class="example">     \label{<var>key</var>}
</pre>
   <p>A <code>\label</code> command appearing in ordinary text assigns to
<var>key</var> the number of the current sectional unit; one appearing
inside a numbered environment assigns that number to <var>key</var>.

   <p>A <var>key</var> name can consist of any sequence of letters, digits, or
punctuation characters.  Upper and lowercase letters are distinguished.

   <p>To avoid accidentally creating two labels with the same name, it is
common to use labels consisting of a prefix and a suffix separated by
a colon or period. Some conventionally-used prefixes:

     <dl>
<dt><code>ch</code><dd>for chapters
<br><dt><code>sec</code><dd>for lower-level sectioning commands
<br><dt><code>fig</code><dd>for figures
<br><dt><code>tab</code><dd>for tables
<br><dt><code>eq</code><dd>for equations
</dl>

   <p>Thus, a label for a figure would look like <code>fig:snark</code> or
<code>fig.snark</code>.

</pre>
   <p>Math arrays are produced with the <code>array</code> environment, normally
within an <code>equation</code> environment (see <a href="#equation">equation</a>).  It has a
single mandatory <var>template</var> argument describing the number of
columns and the alignment within them.  Each column <var>col</var> is
specified by a single letter that tells how items in that row should
be formatted, as follows:

     <dl>
<dt><code>c</code><dd>centered
<br><dt><code>l</code><dd>flush left
<br><dt><code>r</code><dd>flush right
</dl>

   <p><a name="index-g_t_005c_005c-_0028for-_0040code_007barray_007d_0029-192"></a>Column entries are separated by <code>&amp;</code>.  Column entries may include
other LaTeX commands.  Each row of the array is terminated with
<code>\\</code>.

   <p><a name="index-g_t_0040_0040_0040_007b_002e_002e_002e_0040_007d-193"></a>In the template, the construct <code>@{</code><var>text</var><code>}</code> puts <var>text</var>
between columns in each row.

   <p>Here's an example:

<pre class="example">     \begin{equation}
       \begin{array}{lrc}
       left1 &amp; right1 &amp; centered1 \\

   <p><a name="index-g_t_005carraycolsep-194"></a>The <code>\arraycolsep</code> parameter defines half the width of the space
separating columns; the default is &lsquo;<samp><span class="samp">5pt</span></samp>&rsquo;.  See <a href="#tabular">tabular</a>, for other
parameters which affect formatting in <code>array</code> environments,
namely <code>\arrayrulewidth</code> and <code>\arraystretch</code>.

   <p>The <code>array</code> environment can only be used in math mode.

<p><a name="index-g_t_005ccentering-198"></a><a name="index-centering-text_002c-declaration-for-199"></a>
The <code>\centering</code> declaration corresponds to the <code>center</code>
environment.  This declaration can be used inside an environment such
as <code>quote</code> or in a <code>parbox</code>.  Thus, the text of a figure or
table can be centered on the page by putting a <code>\centering</code>
command at the beginning of the figure or table environment.

   <p>Unlike the <code>center</code> environment, the <code>\centering</code> command
does not start a new paragraph; it simply changes how LaTeX formats
paragraph units.  To affect a paragraph unit's format, the scope of
the declaration must contain the blank line or <code>\end</code> command (of
an environment such as quote) that ends the paragraph unit.

   <p>Here's an example:

<pre class="example">     \begin{quote}
     \centering
     first line \\
     second line \\

   <p><a name="index-bold-typewriter_002c-avoiding-204"></a><a name="index-typewriter-labels-in-lists-205"></a>Another variation: since the bold style is applied to the labels, if
you typeset a label in typewriter using <code>\texttt</code>, you'll get
bold typewriter: <code>\item[\texttt{bold and typewriter}]</code>.  This
may be too bold, among other issues.  To get just typewriter, use
<code>\tt</code>, which resets all other style variations: <code>\item[{\tt
plain typewriter}]</code>.

</pre>
   <p>The <code>enumerate</code> environment produces a numbered list.  Enumerations
can be nested within one another, up to four levels deep.  They can also
be nested within other paragraph-making environments, such as
<code>itemize</code> (see <a href="#itemize">itemize</a>) and <code>description</code>
(see <a href="#description">description</a>).

   <p><a name="index-g_t_005citem-210"></a>Each item of an enumerated list begins with an <code>\item</code> command. 
There must be at least one <code>\item</code> command within the environment.

   <p>By default, the numbering at each level is done like this:

     <ol type=1 start=1>
<li>1., 2., <small class="dots">...</small>
<li>(a), (b), <small class="dots">...</small>
<li>i., ii., <small class="dots">...</small>

through <code>\enumiv</code> counters (see <a href="#Counters">Counters</a>).  If the optional
argument to <code>\item</code> is given, the counter is not incremented for
that item.

   <p><a name="index-g_t_005clabelenumi-215"></a><a name="index-g_t_005clabelenumii-216"></a><a name="index-g_t_005clabelenumiii-217"></a><a name="index-g_t_005clabelenumiv-218"></a>The <code>enumerate</code> environment uses the commands <code>\labelenumi</code>
through <code>\labelenumiv</code> to produce the default label.  So, you can
use <code>\renewcommand</code> to change the labels (see <a href="#g_t_005cnewcommand-_0026-_005crenewcommand">\newcommand &amp; \renewcommand</a>).  For instance, to have the first level use uppercase
letters:

</pre>
   <p>Figures are objects that are not part of the normal text, and are
instead &ldquo;floated&rdquo; to a convenient place, such as the top of a page. 
Figures will not be split between two pages.

   <p>The optional argument <code>[placement]</code> determines where LaTeX will try
to place your figure.  There are four places where LaTeX can possibly
put a float:

     <ol type=1 start=1>
<li><code>h</code> (Here) - at the position in the text where the figure
environment appears. 
<li><code>t</code> (Top) - at the top of a text page. 
<li><code>b</code> (Bottom) - at the bottom of a text page. 
<li><code>p</code> (Page of floats) - on a separate float page, which is a page
containing no text, only floats.
        </ol>

   <p>The standard report and article classes use the default placement
<code>tbp</code>.

   <p>The body of the figure is made up of whatever text, LaTeX commands, etc. 
you wish.

   <p><a name="index-g_t_005ccaption-234"></a>The <code>\caption</code> command specifies caption <var>text</var> for the
figure.  The caption is numbered by default.  If <var>loftitle</var> is
present, it is used in the list of figures instead of <var>text</var>
(see <a href="#Tables-of-contents">Tables of contents</a>).

   <p>The <code>itemize</code> environment produces an &ldquo;unordered&rdquo;, &ldquo;bulleted&rdquo;
list.  Itemizations can be nested within one another, up to four
levels deep.  They can also be nested within other paragraph-making
environments, such as <code>enumerate</code> (see <a href="#enumerate">enumerate</a>).

   <p>Each item of an <code>itemize</code> list begins with an <code>\item</code> command. 
There must be at least one <code>\item</code> command within the environment.

   <p>By default, the marks at each level look like this:

     <ol type=1 start=1>
<li>&bull;
<li><b>--<!-- /@w --></b> (bold en-dash)
<li>*
<li>. (centered dot, rendered here as a period)

through <code>\labelitemiv</code> to produce the default label.  So, you can
use <code>\renewcommand</code> to change the labels.  For instance, to have
the first level use diamonds:

the distance between the left margin of the enclosing environment and
the left margin of the list.  By convention, <code>\leftmargin</code> is set
to the appropriate <code>\leftmargin</code><var>N</var> when a new level of
nesting is entered.

   <p>The defaults vary from &lsquo;<samp><span class="samp">.5em</span></samp>&rsquo; (highest levels of nesting) to
&lsquo;<samp><span class="samp">2.5em</span></samp>&rsquo; (first level), and are a bit reduced in two-column mode. 
This example greatly reduces the margin space for outermost lists:

<h3 class="section">8.15 <code>list</code></h3>

<p><a name="index-list-286"></a><a name="index-lists-of-items_002c-generic-287"></a>
The <code>list</code> environment is a generic environment which is used for
defining many of the more specific environments. It is seldom used in
documents, but often in macros.

<pre class="example">     \begin{list}{<var>labeling</var>}{<var>spacing</var>}
     \item <var>item1</var>
     \item <var>item2</var>
     ...
     \end{list}
</pre>
   <p>The mandatory <var>labeling</var> argument specifies how items should be
labelled (unless the optional argument is supplied to <code>\item</code>). 
This argument is a piece of text that is inserted in a box to form the
label.  It can and usually does contain other LaTeX commands.

   <p>The mandatory <var>spacing</var> argument contains commands to change the
spacing parameters for the list.  This argument will most often be
empty, i.e., <code>{}</code>, which leaves the default spacing.

   <p>The <code>math</code> environment inserts the given <var>math</var> within the

<pre class="example">     \begin{minipage}[<var>position</var>]{<var>width</var>}
     <var>text</var>
     \end{minipage}
</pre>
   <p>The <code>minipage</code> environment typesets its body <var>text</var> in a
block that will not be broken across pages (similar to the
<code>\parbox</code> command, see <a href="#g_t_005cparbox">\parbox</a>).  You may use other
paragraph-making environments inside a minipage (unlike <code>\parbox</code>).

<!-- (xxref positions) -->
   <p>It takes an optional <var>position</var> argument for placing <var>text</var>,
and a mandatory <var>width</var> argument for specifying the line width.

environment.  You can restore indentation with a command such as
<code>\setlength{\parindent}{1pc}</code> command.

   <p><a name="index-footnotes-in-figures-295"></a><a name="index-figures_002c-footnotes-in-296"></a>Footnotes in a <code>minipage</code> environment are handled in a way that is
particularly useful for putting footnotes in figures or tables.  A
<code>\footnote</code> or <code>\footnotetext</code> command puts the footnote at
the bottom of the minipage instead of at the bottom of the page, and it
uses the <code>\mpfootnote</code> counter instead of the ordinary
<code>footnote</code> counter (see <a href="#Counters">Counters</a>).

   <p>However, don't put one minipage inside another if you are using
footnotes; they may wind up at the bottom of the wrong minipage.

<h3 class="section">8.18 <code>picture</code></h3>

<p><a name="index-picture-297"></a><a name="index-creating-pictures-298"></a><a name="index-pictures_002c-creating-299"></a>
<pre class="example">     \begin{picture}(width,height)(x offset,y offset)
     ... <var>picture commands</var> ...
     \end{picture}
</pre>
   <p><a name="index-g_t_005cunitlength-300"></a>The <code>picture</code> environment allows you to create just about any
kind of picture you want containing text, lines, arrows and circles. 
You tell LaTeX where to put things in the picture by specifying
their coordinates.  A coordinate is a number that may have a decimal
point and a minus sign&mdash;a number like <code>5</code>, <code>0.3</code> or
<code>-3.1416</code>.  A coordinate specifies a length in multiples of the
unit length <code>\unitlength</code>, so if <code>\unitlength</code> has been set
to <code>1cm</code>, then the coordinate 2.54 specifies a length of 2.54
centimeters.  You should only change the value of <code>\unitlength</code>,
using the <code>\setlength</code> command, outside of a <code>picture</code>
environment.

   <p>A position is a pair of coordinates, such as <code>(2.4,-5)</code>, specifying
the point with x-coordinate <code>2.4</code> and y-coordinate <code>-5</code>. 
Coordinates are specified in the usual way with respect to an origin,
which is normally at the lower-left corner of the picture.  Note that
when a position appears as an argument, it is not enclosed in braces;
the parentheses serve to delimit the argument.

   <p>The <code>picture</code> environment has one mandatory argument, which is a
<code>position</code>.  It specifies the size of the picture.  The environment
produces a rectangular box with width and height determined by this
argument's x- and y-coordinates.

   <p>The <code>picture</code> environment also has an optional <code>position</code>
argument, following the <code>size</code> argument, that can change the
origin.  (Unlike ordinary optional arguments, this argument is not
contained in square brackets.) The optional argument gives the
coordinates of the point at the lower-left corner of the picture
(thereby determining the origin).  For example, if <code>\unitlength</code>
has been set to <code>1mm</code>, the command
<pre class="example">        \begin{picture}(100,200)(10,20)
</pre>
   <p>produces a picture of width 100 millimeters and height 200
millimeters, whose lower-left corner is the point (10,20) and whose
upper-right corner is therefore the point (110,220).  When you first
draw a picture, you will omit the optional argument, leaving the origin
at the lower-left corner.  If you then want to modify your picture by
shifting everything, you just add the appropriate optional argument.

   <p>The environment's mandatory argument determines the nominal size of the
picture.  This need bear no relation to how large the picture really is;
LaTeX will happily allow you to put things outside the picture, or even
off the page.  The picture's nominal size is used by LaTeX in determining
how much room to leave for it.

   <p>Everything that appears in a picture is drawn by the <code>\put</code>
command. The command

<pre class="example">     \put (11.3,-.3){...}
</pre>
   <p class="noindent">puts the object specified by <code>...</code> in the
picture, with its reference point at coordinates (11.3,-.3). 
The reference points for various objects will be described below.

   <p><a name="index-lR-box-301"></a>The <code>\put</code> command creates an <dfn>LR box</dfn>.  You can put anything
that can go in an <code>\mbox</code> (see <a href="#g_t_005cmbox">\mbox</a>) in the text argument of
the <code>\put</code> command.  When you do this, the reference point will
be the lower left corner of the box.

   <p>The <code>picture</code> commands are described in the following sections.

<ul class="menu">
<li><a accesskey="1" href="#g_t_005ccircle">\circle</a>:              Draw a circle.

</pre>
   <p>The <code>tabbing</code> environment provides a way to align text in
columns.  It works by setting tab stops and tabbing to them much as
was done on an ordinary typewriter.  It is best suited for cases where
the width of each column is constant and known in advance.

   <p>This environment can be broken across pages, unlike the <code>tabular</code>
environment.

   <p>The following commands can be used inside a <code>tabbing</code> enviroment:

     <dl>
<dt><code>\\ </code><span class="roman">tabbing</span><a name="index-g_t_005c_005c-_0040r_007btabbing_007d-331"></a><dd>End a line.

     <br><dt><code>\= </code><span class="roman">(tabbing)</span><a name="index-g_t_005c_003d-_0040r_007b_0028tabbing_0029_007d-332"></a><dd>Sets a tab stop at the current position.

     <br><dt><code>\&gt; </code><span class="roman">(tabbing)</span><a name="index-g_t_005c_003e-_0040r_007b_0028tabbing_0029_007d-333"></a><dd><a name="index-g_t_005c_003e-334"></a>Advances to the next tab stop.

     <br><dt><code>\&lt;</code><a name="index-g_t_005c_003c-335"></a><dd>Put following text to the left of the local margin (without changing
the margin).  Can only be used at the start of the line.

     <br><dt><code>\+</code><a name="index-g_t_005c_002b-336"></a><dd>Moves the left margin of the next and all the
following commands one tab stop to the right, beginning tabbed line if
necessary.

     <br><dt><code>\-</code><a name="index-g_t_005c_002d-337"></a><dd>Moves the left margin of the next and all the
following commands one tab stop to the left, beginning tabbed line if
necessary.

     <br><dt><code>\' </code><span class="roman">(tabbing)</span><a name="index-g_t_005c_0027-_0040r_007b_0028tabbing_0029_007d-338"></a><dd>Moves everything that you have typed so far in the
current column, i.e. everything from the most recent <code>\&gt;</code>,
<code>\&lt;</code>, <code>\'</code>, <code>\\</code>, or <code>\kill</code> command, to the right
of the previous column, flush against the current column's tab stop.

     <br><dt><code>\` </code><span class="roman">(tabbing)</span><a name="index-g_t_005c_0060-_0040r_007b_0028tabbing_0029_007d-339"></a><dd>Allows you to put text flush right against any tab stop, including tab
stop&nbsp;0.  However, it can't move text to the right of the last column
because there's no tab stop there.  The <code>\`</code> command moves all the
text that follows it, up to the <code>\\</code> or <code>\end{tabbing}</code>
command that ends the line, to the right margin of the tabbing
environment.  There must be no <code>\&gt;</code> or <code>\'</code> command between
the <code>\`</code> and the command that ends the line.

     <br><dt><code>\a </code><span class="roman">(tabbing)</span><a name="index-g_t_005ca-_0040r_007b_0028tabbing_0029_007d-340"></a><dd><a name="index-g_t_005ca_0027-_0040r_007b_0028acute-accent-in-tabbing_0029_007d-341"></a><a name="index-g_t_005ca_0060-_0040r_007b_0028grave-accent-in-tabbing_0029_007d-342"></a><a name="index-g_t_005ca_003d-_0040r_007b_0028macron-accent-in-tabbing_0029_007d-343"></a>In a <code>tabbing</code> environment, the commands <code>\=</code>, <code>\'</code> and
<code>\`</code> do not produce accents as usual (see <a href="#Accents">Accents</a>).  Instead,
the commands <code>\a=</code>, <code>\a'</code> and <code>\a`</code> are used.

     <br><dt><code>\kill</code><a name="index-g_t_005ckill-344"></a><dd>Sets tab stops without producing text.  Works just like <code>\\</code>
except that it throws away the current line instead of producing
output for it.  The effect of any <code>\=</code>, <code>\+</code> or <code>\-</code>
commands in that line remain in effect.

     <br><dt><code>\poptabs</code><a name="index-g_t_005cpoptabs-345"></a><dd><a name="index-g_t_005cpoptabs-346"></a>Restores the tab stop positions saved by the last <code>\pushtabs</code>.

     <br><dt><code>\pushtabs</code><a name="index-g_t_005cpushtabs-347"></a><dd>Saves all current tab stop positions. Useful for temporarily changing
tab stop positions in the middle of a <code>tabbing</code> environment.

     <br><dt><code>\tabbingsep</code><a name="index-g_t_005ctabbingsep-348"></a><dd>Distance to left of tab stop moved by <code>\'</code>.

   </dl>

   <p>This example typesets a Pascal function in a traditional format:

<pre class="example">     \begin{tabbing}
     function \= fact(n : integer) : integer;\\

Synopsis:

<pre class="example">      \begin{table}[placement]
     
       body of the table
     
      \caption{table title}
      \end{table}
</pre>
   <p>Tables are objects that are not part of the normal text, and are
usually &ldquo;floated&rdquo; to a convenient place, like the top of a page. 
Tables will not be split between two pages.

   <p>The optional argument <code>[placement]</code> determines where LaTeX will try
to place your table.  There are four places where LaTeX can possibly put
a float:

     <ul>
<li><code>h</code>: Here - at the position in the text where the table
environment appears. 
<li><code>t</code>: Top - at the top of a text page. 
<li><code>b</code>: Bottom - at the bottom of a text page. 
<li><code>p</code>: Page of floats - on a separate float page, which is a page
containing no text, only floats. 
</ul>

   <p>The standard <code>report</code> and <code>article</code> classes use the default
placement <code>[tbp]</code>.

   <p>The body of the table is made up of whatever text, LaTeX commands, etc.,
you wish.  The <code>\caption</code> command allows you to title your table.

</pre>
   <p>These environments produce a box consisting of a sequence of rows of
items, aligned vertically in columns.

   <p><a name="index-g_t_005c_005c-_0040r_007bfor-_0040code_007btabular_007d_007d-355"></a><code>\\</code> must be used to specify the end of each row of the table,
except for the last, where it is optional&mdash;unless an <code>\hline</code>
command (to put a rule below the table) follows.

   <p>The mandatory and optional arguments consist of:

     <dl>
<dt><code>width</code><dd>Specifies the width of the <code>tabular*</code> environment.  There must be
rubber space between columns that can stretch to fill out the specified
width. 
<br><dt><code>pos</code><dd>Specifies the vertical position; default is alignment on the centre of
the environment.

          <ul>
<li><code>t</code> - align on top row
<li><code>b</code> - align on bottom row
</ul>

     <br><dt><code>cols</code><dd>Specifies the column formatting.  It consists of a sequence of the
following specifiers, corresponding to the sequence of columns and
intercolumn material.

          <ul>
<li><code>l</code> - A column of left-aligned items. 
<li><code>r</code> - A column of right-aligned items. 
<li><code>c</code> - A column of centred items. 
<li><code>|</code> - A vertical line the full height and depth of the environment. 
<li><code>@{text}</code> - This inserts <code>text</code> in every row.  An @-expression
suppresses the intercolumn space normally inserted between columns; any
desired space between the inserted text and the adjacent items must be
included in text.  An <code>\extracolsep{wd}</code> command in an
@-expression causes an extra space of width <code>wd</code> to appear to the
left of all subsequent columns, until countermanded by another
<code>\extracolsep</code> command.  Unlike ordinary intercolumn space, this
extra space is not suppressed by an @-expression.  An
<code>\extracolsep</code> command can be used only in an @-expression in the
<code>cols</code> argument. 
<li><code>p{wd}</code> - Produces a column with each item typeset in a parbox of
width <code>wd</code>, as if it were the argument of a <code>\parbox[t]{wd}</code>
command.  However, a <code>\\</code> may not appear in the item, except in the
following situations:
               <ol type=1 start=1>
<li>inside an environment like <code>minipage</code>, <code>array</code>, or <code>tabular</code>. 
<li>inside an explicit <code>\parbox</code>. 
<li>in the scope of a <code>\centering</code>, <code>\raggedright</code>, or <code>\raggedleft</code>
declaration.  The latter declarations must appear inside braces or an
environment when used in a <code>p</code>-column element.
               </ol>
<li><code>*{num}{cols}</code> - Equivalent to <code>num</code> copies of
<code>cols</code>, where <code>num</code> is any positive integer and <code>cols</code> is
any list of column-specifiers, which may contain another
<code>*-expression</code>.

     </ul>

</pre>
   <p>The <code>\multicolumn</code> command makes an entry that spans several
columns.  The first mandatory argument, <var>cols</var>, specifies the
number of columns to span.  The second mandatory argument, <var>pos</var>,
specifies the formatting of the entry; <code>c</code> for centered, <code>l</code>
for flushleft, <code>r</code> for flushright.  The third mandatory argument,
<var>text</var>, specifies what text to put in the entry.

   <p>Here's an example showing two columns separated by an en-dash;
<code>\multicolumn</code> is used for the heading:

</pre>
   <p>The <code>thebibliography</code> environment produces a bibliography or
reference list.

   <p>In the <code>article</code> class, this reference list is labelled
&ldquo;References&rdquo;; in the <code>report</code> class, it is labelled
&ldquo;Bibliography&rdquo;.  You can change the label (in the standard classes)
by redefining the command <code>\refname</code>.  For instance, this
eliminates it entirely:

<pre class="example">     \renewcommand{\refname}{}
</pre>
   <p>The mandatory <var>widest-label</var> argument is text that, when typeset,
is as wide as the widest item label produced by the <code>\bibitem</code>
commands.  It is typically given as <code>9</code> for bibliographies with
less than 10 references, <code>99</code> for ones with less than 100, etc.

   <p>The <code>\bibitem</code> command generates an entry labelled by

automatically generated using the <code>enumi</code> counter.  The
<var>cite_key</var> is any sequence of letters, numbers, and punctuation
symbols not containing a comma.

   <p>This command writes an entry to the <samp><span class="file">.aux</span></samp> file containing the
item's <var>cite_key</var> and label.  When the <samp><span class="file">.aux</span></samp> file is read by
the <code>\begin{document}</code> command, the item's <code>label</code> is
associated with <code>cite_key</code>, causing references to <var>cite_key</var>

<p><a name="index-using-Bib_0040TeX_007b_007d-369"></a><a name="index-bib_0040TeX_007b_007d_002c-using-370"></a><a name="index-bibliography_002c-creating-_0028automatically_0029-371"></a><a name="index-g_t_005cbibliographystyle-372"></a><a name="index-g_t_005cbibliography-373"></a>
If you use the BibTeX program by Oren Patashnik (highly
recommended if you need a bibliography of more than a couple of
titles) to maintain your bibliography, you don't use the
<code>thebibliography</code> environment (see <a href="#thebibliography">thebibliography</a>). Instead,
you include the lines

<pre class="example">     \bibliographystyle{<var>bibstyle</var>}
     \bibliography{<var>bibfile1</var>,<var>bibfile2</var>}
</pre>
   <p>The <code>\bibliographystyle</code> command does not produce any output of
its own.  Rather, it defines the style in which the bibliography will
be produced: <var>bibstyle</var> refers to a file
<var>bibstyle</var><samp><span class="file">.bst</span></samp>, which defines how your citations will look. 
The standard <var>style</var> names distributed with BibTeX are:

     <dl>
<dt><code>alpha</code><dd>Sorted alphabetically. Labels are formed from name of author and year of
publication. 
<br><dt><code>plain</code><dd>Sorted alphabetically. Labels are numeric. 
<br><dt><code>unsrt</code><dd>Like <code>plain</code>, but entries are in order of citation. 
<br><dt><code>abbrv</code><dd>Like <code>plain</code>, but more compact labels. 
</dl>

   <p>In addition, numerous other BibTeX style files exist tailored to
the demands of various publications.  See
<a href="http://www.ctan.org/tex-archive/biblio/bibtex/contrib">http://www.ctan.org/tex-archive/biblio/bibtex/contrib</a>.

   <p>The <code>\bibliography</code> command is what actually produces the
bibliography.  The argument to <code>\bibliography</code> refers to files
named <samp><var>bibfile</var><span class="file">.bib</span></samp>, which should contain your database in
BibTeX format.  Only the entries referred to via <code>\cite</code> and
<code>\nocite</code> will be listed in the bibliography.

   <p>The <code>titlepage</code> environment creates a title page, i.e., a page
with no printed page number or heading.  It also causes the following
page to be numbered page one.  Formatting the title page is left to
you.  The <code>\today</code> command may be useful on title pages
(see <a href="#g_t_005ctoday">\today</a>).

   <p>You can use the <code>\maketitle</code> command (see <a href="#g_t_005cmaketitle">\maketitle</a>) to
produce a standard title page without a <code>titlepage</code> environment.

   <p>The <code>verbatim</code> environment is a paragraph-making environment in

<code>\</code> character produces a printed &lsquo;<samp><span class="samp">\</span></samp>&rsquo;.  It turns LaTeX

effect that they would on a typewriter.

   <p>The <code>\footnote</code> command places the numbered footnote <var>text</var>
at the bottom of the current page.  The optional argument <var>number</var>
changes the default footnote number.

   <p>This command can only be used in outer paragraph mode; i.e., you

With no optional argument, the <code>\footnotemark</code> command puts the
current footnote number in the text.  This command can be used in
inner paragraph mode.  You give the text of the footnote separately,
with the <code>\footnotetext</code> command.

   <p>This command can be used to produce several consecutive footnote
markers referring to the same footnote with

<pre class="example">     \footnotemark[\value{footnote}]

   <p>This command defines a theorem-like environment.  Arguments:

     <dl>
<dt><var>newenv</var><dd>The name of the environment to be defined; must not be the name of an
existing environment or otherwise defined.

     <br><dt><var>label</var><dd>The text printed at the beginning of the environment, before the
number. For example, &lsquo;<samp><span class="samp">Theorem</span></samp>&rsquo;.

     <br><dt><var>numbered_like</var><dd>(Optional.)  The name of an already defined theorem-like environment;
the new environment will be numbered just like <var>numbered_like</var>.

     <br><dt><var>within</var><dd>(Optional.)  The name of an already defined counter, a sectional unit. 
The new theorem counter will be reset at the same time as the

<p><a name="index-counters_002c-a-list-of-423"></a><a name="index-variables_002c-a-list-of-424"></a>
Everything LaTeX numbers for you has a counter associated with
it. The name of the counter is the same as the name of the environment
or command that produces the number, except with no <code>\</code>. 
(<code>enumi</code>&ndash;<code>enumiv</code> are used for the nested enumerate
environment.)  Below is a list of the counters used in LaTeX's
standard document classes to control numbering.

<pre class="example">     part            paragraph       figure          enumi

(<code>\year</code>, Common Era).  When TeX starts up, they are
set to the current values on the system where TeX is running.  They
are not updated as the job progresses.

   <p>The related command <code>\today</code> produces a string representing the
current day (see <a href="#g_t_005ctoday">\today</a>).

<h2 class="chapter">13 Line breaking</h2>

<p><a name="index-line-breaking-459"></a><a name="index-breaking-lines-460"></a>
The first thing LaTeX does when processing ordinary text is to
translate your input file into a sequence of glyphs and spaces.  To
produce a printed document, this sequence must be broken into lines
(and these lines must be broken into pages).

   <p>LaTeX usually does the line (and page) breaking for you, but in
some environments, you do the line breaking yourself with the
<code>\\</code> command, and you can always manually force breaks.

<ul class="menu">
<li><a accesskey="1" href="#g_t_005c_005c">\\</a>:                          Start a new line.

The <code>\\</code> command tells LaTeX to start a new line.  It has an
optional argument, <var>morespace</var>, that specifies how much extra
vertical space is to be inserted before the next line.  This can be a
negative amount.

   <p>The <code>\\*</code> command is the same as the ordinary <code>\\</code> command
except that it tells LaTeX not to start a new page after the line.

in the output.

The <code>\-</code> command tells LaTeX that it may hyphenate the word at

find most of the correct hyphenation points, and almost never use an
incorrect one.  The <code>\-</code> command is used for the exceptional

   <p>When you insert <code>\-</code> commands in a word, the word will only be
hyphenated at those points and not at any of the hyphenation points

   <p>The <code>\hyphenation</code> command declares allowed hyphenation points
with a <code>-</code> character in the given words.  The words are separated
by spaces.  TeX will only hyphenate if the word matches exactly, no
inflections are tried.  Multiple <code>\hyphenation</code> commands
accumulate.  Some examples (the default TeX hyphenation patterns
misses the hyphenations in these words):

Synopsis:

<pre class="example">     \marginpar[<var>left</var>]{<var>right</var>}
</pre>
   <p>The <code>\marginpar</code> command creates a note in the margin.  The first
line of the note will have the same baseline as the line in the text
where the <code>\marginpar</code> occurs.

   <p>When you only specify the mandatory argument <var>right</var>, the text
will be placed

     <ul>
<li>in the right margin for one-sided layout;
<li>in the outside margin for two-sided layout;
<li>in the nearest margin for two-column layout. 
</ul>

   <p><a name="index-g_t_005creversemarginpar-507"></a><a name="index-g_t_005cnormalmarginpar-508"></a>The command <code>\reversemarginpar</code> places subsequent marginal notes
in the opposite (inside) margin.  <code>\normalmarginpar</code> places them
in the default position.

   <p>When you specify both arguments, <var>left</var> is used for the left
margin, and <var>right</var> is used for the right margin.

   <p>The first word will normally not be hyphenated; you can enable
hyphenation there by beginning the node with <code>\hspace{0pt}</code>.

   <p>These parameters affect the formatting of the note:

To get an expression <i>exp</i> to appear as a subscript, you just type
<code>_{</code><i>exp</i><code>}</code>.  To get <i>exp</i> to appear as a
superscript, you type <code>^{</code><i>exp</i><code>}</code>. LaTeX handles
superscripted superscripts and all of that stuff in the natural way. 
It even does the right thing when something has both a subscript and a
superscript.

<p><a name="index-math-symbols-531"></a><a name="index-symbols_002c-math-532"></a><a name="index-greek-letters-533"></a>
LaTeX provides almost any mathematical symbol you're likely to
need. The commands for generating them can be used only in math mode. 
For example, if you include <code>$\pi$</code> in your source, you will get
the pi symbol (\pi) in your output.

<p><a name="index-spacing-within-math-mode-812"></a><a name="index-math-mode_002c-spacing-813"></a>
In a <code>math</code> environment, LaTeX ignores the spaces you type and
puts in the spacing according to the normal rules for mathematics
texts.  If you want different spacing, LaTeX provides the following
commands for use in math mode:

     <dl>
<dt><code>\;</code><dd><a name="index-g_t_005c_003b-814"></a>A thick space (5\over18\,quad). 
<br><dt><code>\:</code><dt><code>\&gt;</code><dd><a name="index-g_t_005c_003a-815"></a><a name="index-g_t_005c_003e-816"></a>Both of these produce a medium space (2\over9\,quad). 
<br><dt><code>\,</code><dd><a name="index-g_t_005c_002c-817"></a>A thin space (1\over6\,quad); not restricted to math mode.

<h2 class="chapter">17 Modes</h2>

<p><a name="index-modes-837"></a><a name="index-paragraph-mode-838"></a><a name="index-math-mode-839"></a><a name="index-left_002dto_002dright-mode-840"></a><a name="index-lR-mode-841"></a>

   <p>When LaTeX is processing your input text, it is always in one of three
modes:

     <ul>
<li>Paragraph mode
<li>Math mode
<li>Left-to-right mode, called LR mode for short
</ul>

   <p>LaTeX changes mode only when it goes up or down a staircase to a
different level, though not all level changes produce mode changes. 
Mode changes occur only when entering or leaving an environment, or when
LaTeX is processing the argument of certain text-producing commands.

   <p>&ldquo;Paragraph mode&rdquo; is the most common; it's the one LaTeX is in
when processing ordinary text.  In that mode, LaTeX breaks your
text into lines and breaks the lines into pages.  LaTeX is in
&ldquo;math mode&rdquo; when it's generating a mathematical formula.  In &ldquo;LR
mode&rdquo;, as in paragraph mode, LaTeX considers the output that it
produces to be a string of words with spaces between them.  However,
unlike paragraph mode, LaTeX keeps going from left to right; it
never starts a new line in LR mode.  Even if you put a hundred words
into an <code>\mbox</code>, LaTeX would keep typesetting them from left
to right inside a single box, and then complain because the resulting
box was too wide to fit on the line.

   <p>LaTeX is in LR mode when it starts making a box with an <code>\mbox</code>
command.  You can get it to enter a different mode inside the box - for
example, you can make it enter math mode to put a formula in the box. 
There are also several text-producing commands and environments for
making a box that put LaTeX in paragraph mode.  The box make by one of
these commands or environments will be called a <code>parbox</code>.  When
LaTeX is in paragraph mode while making a box, it is said to be in
&ldquo;inner paragraph mode&rdquo;.  Its normal paragraph mode, which it starts out
in, is called &ldquo;outer paragraph mode&rdquo;.

<h2 class="chapter">19 Spaces</h2>

<p><a name="index-spaces-867"></a>
LaTeX has many ways to produce white (or filled) space.

   <p>Another space-producing command is <code>\,</code> to produce a &ldquo;thin&rdquo;
space (usually 1/6<span class="dmn">quad</span>).  It can be used in text mode, but is
more often useful in math mode  (see <a href="#Spacing-in-math-mode">Spacing in math mode</a>).

</li></ul>
<p>Horizontal space
<ul class="menu">
<li><a accesskey="1" href="#g_t_005chspace">\hspace</a>:              Fixed horizontal space. 
<li><a accesskey="2" href="#g_t_005cSPACE">\SPACE</a>:               Normal interword space. 
<li><a accesskey="3" href="#g_t_005cAT">\AT</a>:                  Ending a sentence. 
<li><a accesskey="4" href="#g_t_005cthinspace">\thinspace</a>:           One-sixth of an em.

<p><a name="index-g_t_005chspace-868"></a>
Synopsis:

<pre class="example">     \hspace[*]{<var>length</var>}
</pre>
   <p>The <code>\hspace</code> command adds horizontal space.  The <var>length</var>
argument can be expressed in any terms that LaTeX understands:
points, inches, etc.  It is a rubber length.  You can add both
negative and positive space with an <code>\hspace</code> command; adding
negative space is like backspacing.

   <p>LaTeX normally removes horizontal space that comes at the beginning
or end of a line.  To preserve this space, use the optional <code>*</code>
form.

<h3 class="section">19.2 <code>\hfill</code></h3>

<p><a name="index-g_t_005chfill-869"></a>The <code>\hfill</code> fill command produces a &ldquo;rubber length&rdquo; which has
no natural space but can stretch or shrink horizontally as far as
needed.

   <p><a name="index-g_t_005cfill-870"></a>The <code>\fill</code> parameter is the rubber length itself (technically,
the glue value &lsquo;<samp><span class="samp">0pt plus1fill</span></samp>&rsquo;); thus, <code>\hspace\fill</code> is
equivalent to <code>\hfill</code>.

The <code>\ </code> (space) command produces a normal interword space.  It's
useful after punctuation which shouldn't end a sentence.  For example
<code>Knuth's article in Proc.\ Amer.\ Math\. Soc.\ is fundamental</code>. 
It is also often used after control sequences, as in <code>\TeX\ is a
nice system.</code>

   <p>In normal circumstances, <code>\</code>&lt;tab&gt; and <code>\</code>&lt;newline&gt;
are equivalent to <code>\ </code>.

<h3 class="section">19.4 <code>\@</code></h3>

<p><a name="index-g_t_005c_0040_0040-874"></a>
The <code>\@</code> command makes the following punctuation character end a
sentence even if it normally would not.  This is typically used after
a capital letter.  Here are side-by-side examples with and without
<code>\@</code>:

<pre class="example">     ... in C\@.  Pascal, though ...
     ... in C.  Pascal, though ...

<h3 class="section">19.6 <code>\/</code></h3>

<p><a name="index-g_t_005c_002f-876"></a>
The <code>\/</code> command produces an <dfn>italic correction</dfn>.  This is a
small space defined by the font designer for a given character,
to avoid the character colliding with whatever follows.  The italic
<i>f</i> character typically has a large italic correction value.

   <p>If the following character is a period or comma, it's not necessary to
insert an italic correction, since those punctuation symbols have a
very small height.  However, with semicolons or colons, as well as
normal letters, it can help. Compare
<i>f: f;</i> (in the TeX output, the `f's are nicely separated)
with <i>f: f;</i>.

   <p>Despite the name, roman characters can also have an italic
correction.  Compare
pdfTeX (in the TeX output, there is a small space after the `f')
with pdfTeX.

   <p>The <code>\addvspace</code> command normally adds a vertical space of height

command will not add more space than needed to make the natural length
of the total vertical space equal to <code>length</code>.

     \framebox[<var>width</var>][<var>position</var>]{<var>text</var>}
</pre>
   <p>The <code>\fbox</code> and <code>\framebox</code> commands are like <code>\mbox</code>,
except that they put a frame around the outside of the box being created.

   <p>In addition, the <code>\framebox</code> command allows for explicit
specification of the box width with the optional <var>width</var> argument
(a dimension), and positioning with the optional <var>position</var>
argument. <!-- xxref -->

   <p><a name="index-g_t_005cfboxrule-895"></a><a name="index-g_t_005cfboxsep-896"></a>Both commands produce a rule of thickness <code>\fboxrule</code> (default

Synopsis:

<pre class="example">     \makebox[<var>width</var>][<var>position</var>]{<var>text</var>}
</pre>
   <p>The <code>\makebox</code> command creates a box just wide enough to contain
the <var>text</var> specified.  The width of the box is specified by the
optional <var>width</var> argument.  The position of the text within the box
is determined by the optional <var>position</var> argument, which may take
the following values:

     <dl>
<dt><code>c</code><dd>Centered (default). 
<br><dt><code>l</code><dd>Flush left. 
<br><dt><code>r</code><dd>Flush right. 
<br><dt><code>s</code><dd>Stretch (justify) across entire <var>width</var>; <var>text</var> must contain
stretchable space for this to work. 
</dl>

   <p><code>\makebox</code> is also used within the picture environment

Synopsis:

<pre class="example">     \parbox[<var>position</var>][<var>height</var>][<var>inner-pos</var>]{<var>width</var>}{<var>text</var>}
</pre>
   <p>The <code>\parbox</code> command produces a box whose contents are created
in <code>paragraph</code> mode.  It should be used to make a box small
pieces of text, with nothing fancy inside.  In particular, you
shouldn't use any paragraph-making environments inside a
<code>\parbox</code> argument.  For larger pieces of text, including ones
containing a paragraph-making environment, you should use a
<code>minipage</code> environment (see <a href="#minipage">minipage</a>).

   <p><code>\parbox</code> has two mandatory arguments:

     <dl>
<dt><var>width</var><dd>the width of the parbox;
<br><dt><var>text</var><dd>the text that goes inside the parbox. 
</dl>

   <p>The optional <var>position</var> argument allows you to align either the
top or bottom line in the parbox with the baseline of the surrounding
text (default is top).

   <p>The optional <var>height</var> argument overrides the natural height of the box.

   <p>The <var>inner-pos</var> argument controls the placement of the text inside
the box, as follows; if it is not specified, <var>position</var> is used.

     <dl>
<dt><code>t</code><dd>text is placed at the top of the box. 
<br><dt><code>c</code><dd>text is centered in the box. 
<br><dt><code>b</code><dd>text is placed at the bottom of the box. 
<br><dt><code>s</code><dd>stretch vertically; the text must contain vertically stretchable space
for this to work.

Synopsis:

<pre class="example">     \raisebox{distance}[<var>height</var>][<var>depth</var>]{text}
</pre>
   <p>The <code>\raisebox</code> command raises or lowers <var>text</var>.  The first
mandatory argument specifies how high <var>text</var> is to be raised (or
lowered if it is a negative amount).  <var>text</var> itself is processed
in LR mode.

   <p>The optional arguments <var>height</var> and <var>depth</var> are dimensions. 
If they are specified, LaTeX treats <var>text</var> as extending a
certain distance above the baseline (height) or below (depth),
ignoring its natural height and depth.

<h3 class="section">21.1 Reserved characters</h3>

<p><a name="index-reserved-characters-904"></a><a name="index-characters_002c-reserved-905"></a>
The following characters play a special role in LaTeX and are called
&ldquo;reserved characters&rdquo; or &ldquo;special characters&rdquo;.

<pre class="example">     # $ % &amp; ~ _ ^ \ { }
</pre>
   <p><a name="index-g_t_005c_0023-906"></a><a name="index-g_t_005c_0024-907"></a><a name="index-g_t_005c_0025-908"></a><a name="index-g_t_005c_0026-909"></a><a name="index-g_t_005c_005f-910"></a><a name="index-g_t_005c_0040_007b-911"></a><a name="index-g_t_005c_0040_007d-912"></a>Whenever you write one of these characters into your file, LaTeX
will do something special.  If you simply want the character to be
printed as itself, include a <code>\</code> in front of the character.  For
example, <code>\$</code> will produce <code>$</code> in your output.

   <p><a name="index-g_t_005cbackslash-913"></a>One exception to this rule is <code>\</code> itself, because <code>\\</code> has
its own special (context-dependent) meaning.  A roman \ is produced by
typing <code>$\backslash$</code> in your file, and a typewriter <code>\</code> is
produced by using &lsquo;<samp><span class="samp">\</span></samp>&rsquo; in a verbatim command (see <a href="#verbatim">verbatim</a>).

   <p><a name="index-g_t_005c_007e-914"></a><a name="index-g_t_005c_005e-915"></a>Also, <code>\~</code> and <code>\^</code> place tilde and circumflex accents over
the following letter, as in &otilde; and &ocirc; (see <a href="#Accents">Accents</a>); to get
a standalone <code>~</code> or <code>^</code>, you can again use a verbatim
command.

   <p><a name="index-g_t_005csymbol-916"></a><a name="index-accessing-any-character-of-a-font-917"></a>
Finally, you can access any character of the current font once you
know its number by using the <code>\symbol</code> command. For example, the
visible space character used in the <code>\verb*</code> command has the code
decimal 32, so it can be typed as <code>\symbol{32}</code>.

   <p>You can also specify octal numbers with <code>'</code> or hexadecimal numbers
with <code>"</code>, so the previous example could also be written as
<code>\symbol{'40}</code> or <code>\symbol{"20}</code>.

&lsquo;<samp><var>month</var> <var>dd</var><span class="samp">, </span><var>yyyy</var></samp>&rsquo;; for example, `July 4, 1976'. 
It uses the predefined counters <code>\day</code>, <code>\month</code>, and
<code>\year</code> (see <a href="#g_t_005cday-_005cmonth-_005cyear">\day \month \year</a>) to do this.  It is not

<p><a name="index-splitting-the-input-file-1015"></a><a name="index-input-file-1016"></a>
A large document requires a lot of input.  Rather than putting the whole
input in a single large file, it's more efficient to split it into
several smaller ones.  Regardless of how many separate files you use,
there is one that is the root file; it is the one whose name you type
when you run LaTeX.

   <p>The <code>\includeonly</code> command controls which files will be read by
subsequent <code>\include</code> commands.  The list of filenames is
comma-separated. Each <var>file</var> must exactly match a filename

or &lsquo;<samp><span class="samp">foo.bar.tex</span></samp>&rsquo;).  If that is not found, the original <var>file</var>

<p><a name="index-table-of-contents_002c-creating-1021"></a>
<a name="index-g_t_005ctableofcontents-1022"></a>A table of contents is produced with the <code>\tableofcontents</code>
command.  You put the command right where you want the table of
contents to go; LaTeX does the rest for you.  A previous run must
have generated a <samp><span class="file">.toc</span></samp> file.

   <p>The <code>\tableofcontents</code> command produces a heading, but it does
not automatically start a new page.  If you want a new page after the
table of contents, write a <code>\newpage</code> command after the
<code>\tableofcontents</code> command.

   <p><a name="index-g_t_005clistoffigures-1023"></a><a name="index-g_t_005clistoftables-1024"></a>The analagous commands <code>\listoffigures</code> and <code>\listoftables</code>

<h2 class="chapter">24 Letters</h2>

<p><a name="index-letters-1043"></a><a name="index-creating-letters-1044"></a>
You can use LaTeX to typeset letters, both personal and business.  The
<code>letter</code> document class is designed to make a number of letters at
once, although you can make just one if you so desire.

   <p>Your <samp><span class="file">.tex</span></samp> source file has the same minimum commands as the other
document classes, i.e., you must have the following commands as a
minimum:

<pre class="example">      \documentclass{letter}
      \begin{document}
       ... letters ...
      \end{document}
</pre>
   <p>Each letter is a <code>letter</code> environment, whose argument is the name
and address of the recipient.  For example, you might have:

<pre class="example">      \begin{letter}{Mr. Joe Smith\\ 2345 Princess St.
           \\ Edinburgh, EH1 1AA}
        ...
      \end{letter}
</pre>
   <p>The letter itself begins with the <code>\opening</code> command.  The text of
the letter follows.  It is typed as ordinary LaTeX input.  Commands that
make no sense in a letter, like <code>\chapter</code>, do not work.  The letter
closes with a <code>\closing</code> command.

   <p><a name="index-g_t_005c_005c-_0040r_007bfor-letters_007d-1045"></a>After the <code>closing</code>, you can have additional material.  The
<code>\cc</code> command produces the usual &ldquo;cc: <small class="dots">...</small>&rdquo;.  There's also a
similar <code>\encl</code> command for a list of enclosures. With both these
commands, use <code>\\</code> to separate the items.

   <p>These commands are used with the <code>letter</code> class.

The <code>\address</code> specifies the return address of a letter, as it
should appear on the letter and the envelope.  Separate lines of the
address should be separated by <code>\\</code> commands.

   <p>If you do not make an <code>\address</code> declaration, then the letter
will be formatted for copying onto your organisation's standard
letterhead.  (See <a href="#Overview">Overview</a>, for details on your local
implementation).  If you give an <code>\address</code> declaration, then the
letter will be formatted as a personal letter.

Synopsis:

<pre class="example">     \typein[<var>\cmd</var>]{<var>msg</var>}
</pre>
   <p><code>\typein</code> prints <var>msg</var> on the terminal and causes LaTeX to
stop and wait for you to type a line of input, ending with return.  If
the optional <var>\cmd</var> argument is omitted, the typed input is
processed as if it had been included in the input file in place of the
<code>\typein</code> command.  If the <var>\cmd</var> argument is present, it
must be a command name.  This command name is then defined or
redefined to be the typed input.

<h3 class="section">25.2 <code>\typeout{</code><var>msg</var><code>}</code></h3>

<p><a name="index-g_t_005ctypeout-1068"></a>
Synopsis:

<pre class="example">     \typeout{<var>msg</var>}
</pre>
   <p>Prints <code>msg</code> on the terminal and in the <code>log</code> file. 
Commands in <code>msg</code> that are defined with <code>\newcommand</code> or
<code>\renewcommand</code> (among others) are replaced by their definitions
before being printed.

   <p>LaTeX's usual rules for treating multiple spaces as a single space
and ignoring spaces after a command name apply to <code>msg</code>.  A
<code>\space</code> command in <code>msg</code> causes a single space to be
printed, independent of surrounding spaces.  A <code>^^J</code> in
<code>msg</code> prints a newline.

<h2 class="chapter">26 Command Line</h2>

<p><a name="index-command-Line-1069"></a>
The input file specification indicates the file to be formatted;
TeX uses <samp><span class="file">.tex</span></samp> as a default file extension.  If you omit the
input file entirely, TeX accepts input from the terminal.  You
specify command options by supplying a string as a parameter to the
command; e.g.

<pre class="example">     latex '\nonstopmode\input foo.tex'
</pre>
   <p class="noindent">will process <samp><span class="file">foo.tex</span></samp> without pausing after every error.

&lsquo;<samp><span class="samp">*</span></samp>&rsquo; prompt, it is waiting for input.  You can type <code>\stop</code>
(and return) and it will prematurely end the document.

\section{Introduction}

This is an example article for \TUB, from
\url{http://tug.org/TUGboat/location.html}.

We recommend the graphicx package for image inclusions, and the hyperref
package for active url's (in the \acro{PDF} output).  \TUB\ is produced
using \acro{PDF} files exclusively, nowadays.

The \texttt{ltug*} classes provide these abbreviations, among many others:
