<span id="index-Tree-structuring"></span>
<p>A Texinfo file is usually structured like a book with chapters,
sections, subsections, and the like. This structure can be visualized
as a tree (or rather as an upside-down tree) with the root at the top
and the levels corresponding to chapters, sections, subsection, and
subsubsections.
</p>
<p>Here is a diagram that shows a Texinfo file with three chapters, each
with two sections.
</p>
<div class="example">
<pre class="example"> Top
|
-------------------------------------
| | |
Chapter 1 Chapter 2 Chapter 3
| | |
-------- -------- --------
| | | | | |
Section Section Section Section Section Section
1.1 1.2 2.1 2.2 3.1 3.2
</pre></div>
<p>In a Texinfo file that has this structure, the beginning of Chapter 2
would be written like this:
</p>
<div class="example">
<pre class="example">@node Chapter 2
@chapter Chapter 2
</pre></div>
<p>For purposes of example, here is how it would be written with
explicit node pointers:
</p>
<div class="example">
<pre class="example">@node Chapter 2, Chapter 3, Chapter 1, Top
@chapter Chapter 2
</pre></div>
<p>The chapter structuring commands are described in the sections that
follow; the <code>@node</code> command is described in
the previous chapter (see <a href="Nodes.html">Nodes</a>).
