shortdesc Package for subequation numbering.
longdesc Sometimes it is necessary to be able to refer to subexpressions of
longdesc an equation. In order to do that these subexpressions should be
longdesc numbered. In standard LaTeX there is no provision for this. To
longdesc solve this problem Stephen Gildea once wrote subeqn.sty for LaTeX
longdesc 2.09; Donald Arsenau rewrote the macros and Johannes Braams made
longdesc them available for LaTeX2e. Note that this package is not
longdesc compatible with the package subeqnarray (written by Johannes
longdesc Braams), but it can be used together with the LaTeX class options
longdesc leqno and fleqn. [description copied from TeX Catalogue]
