5.3 @top

The @top command is a special sectioning command that you use only after an ‘@node Top’ line at the beginning of a Texinfo file. The @top command tells the makeinfo formatter which node is the `Top' node, so it can use it as the root of the node tree if your manual uses implicit node pointers. It has the same typesetting effect as @unnumbered (see section @unnumbered and @appendix). For detailed information, see The @top Command.

The @top node and its menu (if any) is conventionally wrapped in an @ifnottex conditional so that it will appear only in Info and HTML output, not TeX.
