deleq - a L A T E X Macro for Partial Numbering of Equations

To enable a more flexible equation numbering, especially "partial" equation numbers ('3a', '3b' etc.), the deleq package has been developed. It can produce partial equation numbers intermixed with ordinary equation numbers also in an eqnarray-like environment, the inter- mixing can occur within one environment. References to a partially numbered equation can be both the complete equation number ('3b') or only the main equation number ('3'). Further- more, equation numbers can be recycled without disturbing the ordinary equation numbers. The package also provides commands for putting commentatory text in an eqnarray environ- ment. Both standard LATEX class options leqno and fleqn 1 work with deleq.
