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