blocking

I would like to block all countries except mine in iptables, that is a lits with about 100.000 Entries.

how can i define this blacklistfile in a script, so iptables blocks all those ip-ranges?

maybe i can use http://www.ipdeny.com/ipblocks/data/countries/ that provides lists in the form

117.55.192.0/20
117.104.224.0/21
119.59.80.0/21
121.100.48.0/21
...

i want to be able to change the blacklistfile easily without having to change the iptables-script
