{definefontfamily,definefallbackfamily} +%D +%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 mendatory commands which are (a) the name of the fontclass, +%D (b) the styles of the font and (c) the name of the font. +%D +%D
