@xref with One Argument
The simplest form of @xref takes one argument, the name of
another node in the same Info file.    The Info formatters produce
output that the Info readers can use to jump to the reference; TeX
produces output that specifies the page and section number for you.
For example,
     @xref{Tropical Storms}.
     
produces
     *Note Tropical Storms::.
     
and
See Section 3.1 [Tropical Storms], page 24.
(Note that in the preceding example the closing brace is followed by a period.)
You can write a clause after the cross reference, like this:
     @xref{Tropical Storms}, for more info.
     
which produces
     *Note Tropical Storms::, for more info.
     
and
See Section 3.1 [Tropical Storms], page 24, for more info.
(Note that in the preceding example the closing brace is followed by a comma, and then by the clause, which is followed by a period.)
