NamecoinToBind is a php script that generates bind zones for .bit domains from the namecoin blockchain by using the name_scan rpc command.
This version has a first support of the new spec (old spec is still supported for a while) :
apt-get install idn php5-cli
Launch : ./reload_bind.sh & Add it at startup (in /etc/rc.local before line 'exit 0' on debian) :
su -c '/<NamecoinToBind>/reload_bind.sh > /dev/null &'
