%D   {fontstyle,fontalternative,fontsize,fontbody}
%D
%D Within a bodyfont, fonts can come in different sizes. For instance
%D \type {\tf} is accompanied by \type {\tfa}, \type {\tfb} etc. The
%D first two characters denote the alternative, while the third
%D character in these sequences represents the size. The actual size
%D is saved in a macro. The styles, being roman (\type {\rm}), sans
%D serif (\type {\ss}) etc. are also available in macros in \type {rm},
%D \type {ss} etc. form.

% we can use an indirect mapping for fontclasses (map string onto numbers) and indeed this
% is somewhat more efficient but also makes the code messy ... maybe some day ...
