<h3 class="section">5.1 Tree Structure of Sections</h3>
<p><a name="index-Tree-structuring-272"></a>
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>Here is a diagram that shows a Texinfo file with three chapters,
each of which has two sections.
<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>
<p>In a Texinfo file that has this structure, the beginning of Chapter 2
looks like this:
<pre class="example"> @node Chapter 2, Chapter 3, Chapter 1, top
@chapter Chapter 2
</pre>
<p>The chapter structuring commands are described in the sections that
follow; the <code>@node</code> and <code>@menu</code> commands are described in
following chapters. (See <a href="Nodes.html#Nodes">Nodes</a>, and see <a href="Menus.html#Menus">Menus</a>.)
