/*
 * Changelog:
 *
 * 2005-01-13   Andrew Hill, Awarez Ltd. (http://www.awarez.net)
 *              Formatted file according to PEAR library standards.
 *              Moved $GEOIP_COUNTRY_CODE_TO_NUMBER, $GEOIP_COUNTRY_CODES,
 *                  $GEOIP_COUNTRY_CODES3 and $GEOIP_COUNTRY_NAMES into the
 *                  GeoIP class, so that library will still work even when
 *                  not included in the $GLOBAL context.
