It seems that x_netkan_gitlab.use_source_archive: true doesn't actually work or I don't understand how it is supposed to be used?

Yeah, x_netkan_gitlab is an object. I pushed a commit showing the correct usage.

Please don't merge this yet. It's not ready; the latest changes are on a separate branch at https://gitlab.com/ksrss/KSRSS/-/tree/reborn which hasn't had a release made yet. When that happens, the install and relationships will probably change, perhaps drastically.

We'll also need clarification on the textures. The May 2020 release says it depends on https://github.com/KerbalFrench/KSRSS-Textures, but it also contains its own Textures folder, so we'd need to confirm whether that's a real dependency and also whether it's current for this new reborn branch. If so, we'll need to make 3 additional modules for the 4k, 8k, and 16k textures and make them mutually exclusive provides-based dependencies of the main module.

The reborn version does not depend on external textures.

Let's re-open this if a usable release actually happens.
