+mathematical typography.  The style delivers a particular context-dependent
+presentation on the basis of a rather coarse context-independent notation.
+Highlighted features: depending on the context, the command @code{\\frac}
+produces either built-up or case or solidus fractions, with parentheses added
+whenever required for preservation of the mathematical meaning; delimiters
+adapt their size to the material enclosed, rendering @code{\\left} and
+@code{\\right} almost obsolete.")
