Must be called between PetscOptionsBegin() and PetscOptionsEnd(). If newname is provided, the old option is replaced. Otherwise, it remains in the options database. If an option is not replaced, the info argument should be used to advise the user on how to proceed. There is a limit on the length of the warning printed, so very long strings provided as info may be truncated.
