+If the export settings are set such that data loss would occur in the output
+file (i.e, due to the particular choice of data type and/or file type), the
+normal behaviour of <em>r.out.gdal</em> in this case would be to issue an error
+message describing the problem and exit without exporting. The <b>-f</b> flag
+allows raster export even if some of the data loss tests are not passed, and
+warnings are issued instead of errors.
