I'm trying to build a Scribus template for use by people who do not necessarily have some of the fonts that the template prefers.
In CSS one can define a "font-family", such as
font-family: "Times New Roman", Times, serif; or
font-family: Arial, Helvetica, sans-serif; (which isn't really the standard meaning for "font family", but never mind).
But that appears to set user preferences in my instance of Scribus; what I'd like to do is define font substitution preferences for a template instead.
