%D The \tex{definefontfamily} creates like \tex{definetypeface} a collection of font
%D with different styles which can be later called with the \tex{setupbodyfont} command.
%D
%D The command takes three mandatory commands which are (a) the name of the fontclass,
%D (b) the styles of the font and (c) the name of the font.

%D When a document contains different languages and the global font lacks some characters
%D for one language, one could set a different font where these charcters are taken from.
%D This fallback font (there can be more than one for a certain style) could be set with
%D the \tex{definefallbackfamily} command which takes the same argument as
%D the \tex{definefontfamily} command.
