Comment (by Michal Pirog):

Publicly available repo is here:

https://github.com/wofti/CactusSgrid.git

The thorn itself is at the directory "DNSData" ("BNSData" is an old version)

We are using the thornlist "dns.th" from the directory "useful_files" as an argument for "GetComponents".

Finally, we compile Cactus with the option list "dns.cfg" from the directory "useful_files".

PS: "README" is to update. And I need to prepare some .par file for testing. Again: where exactly should I upload this thorn?
