Naming a `Top' Node
===================

  In a cross reference, you must always name a node.  This means that in
order to refer to a whole manual, you must identify the `Top' node by
writing it as the first argument to the `@xref' command.  (This is
different from the way you write a menu entry; see *Note Referring to
Other Info Files: Other Info Files.)  At the same time, to provide a
meaningful section topic or title in the printed cross reference
(instead of the word `Top'), you must write an appropriate entry for
the third argument to the `@xref' command.

Thus, to make a cross reference to `The GNU Make Manual', write:

     @xref{Top, , Overview, make, The GNU Make Manual}.

which produces

     
and

     See section "Overview" in The GNU Make Manual.

In this example, `Top' is the name of the first node, and `Overview' is
the name of the first section of the manual.
