Arguments:
    HAZARD_FILE             Hazard layer file such as a shapefile or tif containing flood, tsunami,
                            volcano, earthquake data. The layer should be accompanied with an appropriate
                            keywords file.
    EXP_FILE                Exposure layer file such as a shapefile or tif containing population,
                            structures (e.g. buildings), roads, etc. data. The layer should be accompanied with
                            an appropriate keywords file.
    AG_FILE                 Path to an aggregation layer such as a shapefile or tif containing village,
                            boundaries, town subdivisions etc. data. The layer should be accompanied with
                            an appropriate keywords file.
    OUTPUT_DIR              Path to the output directory containing the output layers and reports
    FEATURE_TYPE            Any of the following keywords: roads, buildings, building-points, potential-idp, boundary-x(x:1-11)
    XMIN,YMIN,XMAX,YMAX     A quartet of decimal degrees values representing the analysis extent that
                            should be used. The order of the values is significant, representing XMIN, YMIN,
                            XMAX, YMAX. If omitted the union of the hazard and exposure layer extents should be used.
