#
# This is the basic code that is needed at run time within R to
# provide and define the relevant classes.  It is included
# automatically in the generated code by copying the contents of
# srun.swg into the newly created binding code.


# This could be provided as a separate run-time library but this
# approach allows the code to to be included directly into the
# generated bindings and so removes the need to have and install an
# additional library.  We may however end up with multiple copies of
# this and some confusion at run-time as to which class to use. This
# is an issue when we use NAMESPACES as we may need to export certain
# classes.
