Its a very basic perl script for sending templated request to nominet.
IMHO I would say you might as well code your own and understand it, or get one built to your own specs.
I have a web based catching system allowing shed loads of timing options, bounce counting and prediction plus customisation which I am thinking of licensing out.
Anyone interested PM me. Prior requirements must be a budget couple of a grand and a nominet Tag.
Cheers,
Rob.
