  * The expected values come from `contrib/gen_kml_testdata.sh'.  The
  * assertions that prove the scanner did its job rather than just
  * recognising the magic are the bounding box (which is only correct if
  * the lon,lat tuple order was honoured), the first coordinate, the
  * placemark count, the description with its HTML stripped out of the
  * CDATA section, and the LookAt comment -- the viewer's position, which
  * must *not* have been reported as the data's position.
  *
  * @param argc number of arguments (ignored)
  * @param argv arguments (ignored)
  * @return 0 on success
