# this script converts CSV geoip database (free download at http://www.maxmind.com/app/geoip_country)
# to format, suitable for use with nginx_http_geo module (http://sysoev.ru/nginx)
#
# for example, line with ip range
#
#   "62.16.68.0","62.16.127.255","1041253376","1041268735","RU","Russian Federation"
#
# will be converted to four subnetworks:
#
#   62.16.68.0/22 RU;
#   62.16.72.0/21 RU;
#   62.16.80.0/20 RU;
