This code converts the software correlator output into an aips++ MeasurementSet.  The MeasurementSet can be analysed and postprocessed using the standard set of tools that is also used for the EVN hardware correlator at JIVE.  Existing tools can also be used to convert the MeasurementSet into FITS for use with classic AIPS.
