Donald Arseneau submitted an update to the
cases
package.
Version number: 3.0 License type: other-free
Summary description: Numbered cases environment
Announcement text: ----------------------------------------------------------------------
This package provides a LaTeX environment numcases to produce multi-case equations with a separate equation number for each case. There is also a subnumcases environment which numbers each case with the overall equation number plus a letter [8a, 8b, etc.].
Update to cases.sty to have greater compatibility with amsmath and with hyperref. The layout is also changed to resist over-printing equation numbers.
