This happens because the keywords have changed since the tutorial was
written. The tutorial is being updated. In the meantime, you should be
able to update the FEP script yourself based on the current user's

Certainly. You just have to define a dual topology where modifications
happen at two sites, A->B at one site and B->A at the other. To the
FEP code, it just looks like one transformation.
