A small program written in Go that implements "dynamic DNS" or "ddns" for domains hosted on Godaddy.
You will need to get an API key and API secret from Godaddy. Make sure it's a production key, not a testing key.
$ ./godaddns -key="my api key" -secret="my api secret" -domain="example.com" -polling="(optional) polling interval in seconds; defaults to 360 seconds" -subdomain="(optional) if your target domain is subdomain.example.com, put 'subdomain' here; defaults to '@'" -log "(optional) path to log file; defaults to stdout"
