INCLUDE from url/http?

[Roemer]

I think the current implementation only allows including from files, how about also allow including from an URL? Then the partial files could reside in a git repository or artifactory or such.

Yes, as indicated on the README it's in the roadmap, see https://github.com/devthefuture-org/dockerfile-x#todo-next
But it's a lot of work and I don't have so much time for now.
If you want to try a PR I'll be happy to help you with,
instead you'll have to wait some months for this feature ;-)
