Node:Tree Structuring, Next:Structuring Command Types, Up:Structuring
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.
Here is a diagram that shows a Texinfo file with three chapters,
each of which has two sections.
                          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
In a Texinfo file that has this structure, the beginning of Chapter 2
looks like this:
@node Chapter 2, Chapter 3, Chapter 1, top @chapter Chapter 2
The chapter structuring commands are described in the sections that
follow; the @node and @menu commands are described in
following chapters. (See Nodes, and see Menus.)
