=== FGFS Construct ===
The fgfs-construct tool brings all your gathered data together, throws it in a washing machine and spits it out the otherside in format ready for use with FlightGear. Click the "Update list" button to populate the field with all decoded shapefiles. In the list you select all types that you'd like to include in your scenery. Note that you must select "Default" in order to generate anything other than water.
