Is there an SDK still around for 4.x ?

I'm working with a large client migrating their 4.x 3dns boxes to GTM's. I've been able to cobble together some vs status / wip attributes stuff based on scripts by coworkers. The customer has asked me if I can provide one that'll output wip statistics. I've been getting these "over the fence" requests for various different tasks to assist in this conversion effort. A 4.x SDK that is applicable to 4.10+ 3dns would be very helpful.

 

 

using perl for my language of choice, if that matters : )

 

 

Thanks, sorry if it's still around on DC and I missed it.
