Provides commands \setcounterref and \addtocounterref which use the section (or whatever) number from the reference as the value to put into the counter, as in:

    ...\label{sec:foo}
    ...
    \setcounterref{foonum}{sec:foo}
    

Commands \setcounterpageref and \addtocounterpageref do the corresponding thing with the page reference of the label. The author is Heiko Oberdiek.
