-# This is intended to be a Python level example of how one might write a customized
-# time stepping loop. This would replace the functionality of the WarpX::Evolve routine.
-# Wrappers are available for the major pieces of a time step and they would be called
-# here in the appropriate order.
-# Note that this is intended to be an example only and may not be functional. The
-# onestep routine as written here is out of date and is not consistent with WarpX::Evolve.
