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 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

     *Note Overview: (make)Top.

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.
