setting book title page font size

[Mark Summerfield]

Hi,

Does anyone know how to set the title page font size for books?
In book it has the line:

  # @TitlePageFont              { Helvetica Base} # title page font (not size)

There are no other entries for @TitlePage (no @TitlePageFormat for
example), and no mention of setting the size in the user manual that I
can find.

Thanks!
