Automatic download of new data source scripts

Hi,

I am running Tellico 1.3.5, and I discovered only recently the feature that allow to automatically download data source scripts from kde-files (appeared in v1.2).
In particular, tellico is supposed to configure the scripts by itself, but I can't figure out how to provide the information.
I'am about to post updates of some of my scripts, so I'd like to get that issue solved as well.
Is it some specially formatted lines in the script itself ?
