0003 <!-- This document is an unofficial reference manual for LaTeX, a
0004 document preparation system, version of November 2018.
0005 
0006 This manual was originally translated from LATEX.HLP v1.0a in the
0007 VMS Help Library.  The pre-translation version was written by
0008 George D. Greenwade of Sam Houston State University.  The
0009 LaTeX 2.09 version was written by Stephen Gilmore.  The
0010 LaTeX2e version was adapted from this by Torsten Martinsen.  Karl
0011 Berry made further updates and additions, and gratefully acknowledges
0012 using Hypertext Help with LaTeX, by Sheldon Green, and
0013 LaTeX Command Summary (for LaTeX 2.09) by
0014 L. Botway and C. Biemesderfer (published by the TeX Users
0015 Group as TeXniques number 10), as reference material.  We also
0016 gratefully acknowledge additional material appearing in
0017 latex2e-reference by Martin Herbert Dietze.  (From these references no
0018 text was directly copied.)

0121 
0122 <p>Synopsis:
0123 </p>
0124 <div class="example">
0125 <pre class="example">\begin{<var>environment name</var>}
0126   ...
0127 \end{<var>environment name</var>}
0128 </pre></div>
0129 
0130 <p>An area of LaTeX source, inside of which there is a distinct
0131 behavior.  For instance, for poetry in LaTeX put the lines between
0132 <code>\begin{verse}</code> and <code>\end{verse}</code>.
0133 </p>
0134 <div class="example">
0135 <pre class="example">\begin{verse}
0136   There once was a man from Nantucket \\
0137   ...
0138 \end{verse}
0139 </pre></div>
0140 
0141 <p>See <a href="Environments.html#Environments">Environments</a> for a list of environments.  Particularly notable is
0142 that every LaTeX document must have a <code>document</code> environment,
0143 a <code>\begin{document} ... \end{document}</code> pair.
0144 </p>
0145 <p>The <var>environment name</var> at the beginning must exactly match that at
0146 the end.  This includes the case where <var>environment name</var> ends in a
0147 star&nbsp;(<code>*</code>); both the <code>\begin</code> and <code>\end</code> texts must
0148 include the star.
0149 </p>
0150 <p>Environments may have arguments, including optional arguments.  This
0151 example produces a table.  The first argument is optional (and causes
0152 the table to be aligned on its top row) while the second argument is
0153 required (it specifies the formatting of columns).
0154 </p>
0155 <div class="example">
0156 <pre class="example">\begin{tabular}[t]{r|l}
0157   ... rows of table ...
0158 \end{tabular}
