"""
Adds or replaces the station's outer shell and the ice it stands on in an EXISTING station file, in place.
Nothing else in the file is touched: the kit rooms, the dressing and anything moved by hand stay as they are.

    blender -b --factory-startup Anchorage_Station_exterior.blend --python build/apply_exterior.py [-- options]

    --only exterior | ice     do one of the two (default: both)
    --only floe               only the floe's own mesh, swapped in place: the object, the seracs, blocks and drift
                              ice on it and everything else stay untouched (for a new rim or relief)
    --only coolers            only the four ice coolers on the floe (build/coolers.py: the Fab machine, instanced)
    --only relay              only the relay dish on Relay Control's roof (the Sci-Fi Lite pack's satellite): put
                              there, or put back where the recipe has it
    --only outpost            only the outpost: the armour, pylons, portals, roof works and site works over the shell
                              (build/outpost.py); the shell itself, the ice and the rooms stay untouched
    --only doors              only what the door leaves need to open: the slots in the roofs they lift through and the
                              housings over them (new meshes in place for the two shells, the galleries' armour and
                              the roof works); then run build/check_doors.py
    --no-save                 try it without writing the file
    --refresh-materials A,B   rebuild the Blender preview of these Unreal materials (asset names, for example
                              MI_Ice_A-2,M_Cave_SimpleSnow) from build/bl_kit.py; other materials are left alone

Use this, not build_anchorage.py, once the file has been worked on by hand.
