The package provides macros for typesetting math formulas in mixed horizontal and vertical mode, automatically as best fit.

It also provides a macro \inferrule for typeseting fractions where both the numerator and denominator may be sequences of formulas that will be also typeset in a similar way. It can typically be used for typeseting sets of type inference rules or typing derivations. A macro inferrule for typesetting type inference rules.
