An Erlang Extensible Provisioning Protocol (EPP) client for the .co.za domain name registration system. http://whois.co.za
I wrote the client for my site http://domain-name-registration.co.za. I haven't changed the site to use the client fully yet but I used it to get accredited (look for domain-name-registration.co.za at https://www.registry.net.za/accredited_registrars.php).
