617: The collectivity of this routine is complex; only the MPI processes in comm will

3175: If `newname` is provided then the options database will automatically check the database for `oldname`.
3177: The old call `PetscOptionsXXX`(`oldname`) should be removed from the source code when both (1) the call to `PetscOptionsDeprecated()` occurs before the

3179: See `PTScotch_PartGraph_Seq()` for an example of when (1) fails and `SNESTestJacobian()` where an example of (2) fails.
3181: Must be called between `PetscOptionsBegin()` (or `PetscObjectOptionsBegin()`) and `PetscOptionsEnd()`.
3182: Only the process of rank zero that owns the `PetscOptionsItems` are argument (managed by `PetscOptionsBegin()` or

3184: If newname is provided, the old option is replaced. Otherwise, it remains

3186: If an option is not replaced, the info argument should be used to advise the user
