name mhequ category Package shortdesc Multicolumn equations, tags, labels, sub-numbering. longdesc MHequ simplifies the creation of multi-column equation longdesc environments, and to tag the equations therein. It supports sub- longdesc numbers of blocks of equations (like (1.2a), (1.2b), etc) and longdesc references to each equation individually (1.2a) or to the whole longdesc block (1.2). The labels can be shown in draft mode. [description longdesc copied from TeX Catalogue]
