This script aims to create a traditional GeoIP-CSV database from GeoIP's GeoLite2 database files, for use with xtables-addons' xt_geoip module.
Upstream work on the original conversion scripts in xtables-addons is in progress as well:
https://sourceforge.net/p/xtables-addons/xtables-addons/ci/master/tree/geoip/
For conversion, it is required to download an additional file with country names from Geonames.

None, thanks to an insane speed fix by John Hood, github.com/cgull.
- Use Text::CSV for parsing the input data.
- Merge/adopt cgull's geoipnames feature.
