mmdbresolve reads IPv4 and IPv6 addresses on stdin and prints their IP geolocation information on stdout.
       Each input line must contain exactly one address. Output is in INI format, with a section delimiter named
       after the query address followed by a set of "key: value" pairs. A comment beginning with "# End" is
       appended to each section.

       At startup an "[init]" section is printed that shows the status of each datbase and of mmdbresolve
       itself.

       To resolve a single address:

           echo 4.4.4.4 | mmdbresolve -f /usr/share/GeoIP/GeoLite2-City.mmdb

       Exampleoutput

           [init]
           db.0.path: /usr/share/GeoIP/GeoLite2-City.mmdb
           db.0.status: OK
           mmdbresolve.status: true
           # End init
           [4.4.4.4]
           # GeoLite2-City
           country.iso_code: US
           country.names.en: United States
           location.latitude: 37.751000
           location.longitude: -97.822000
           # End 4.4.4.4
