Summary description: Typesetting sequences of math formulas, e.g. type inference rules
Announcement text: ----------------------------------------------------------------------
The package mathpartir provides macros for typesetting math formulas in mixed horizontal and vertical mode, automatically as best fit. It provides an environment mathpar that behaves much as a loose centered paragraph where words are math formulas and spaces between them are larger and adjustable. 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 similar way. It can typically be used for typeseting sets of type inference rules or typing derivations.
