    289327currently instantiated last.
    290328
     329Scripts to start federation are copied into the local experiment's tmp file -
     330e.g., F</proj/DETER/exp/simple-split/tmp>.  These are taken from the directory
     331given by the B<-d> option.
     332
    291333If any sub-experiment fails to instantiate, the other sub-exeriments are
    292334swapped out.
