zeromind.fork

Fork a world into your own worlds, the way a repository is forked. The fork is a world of its own that you can change freely, and its content keeps pointing at the worlds that made it, so a change made in the fork can be proposed back to the world it was forked from with a pull request.

Pass the guid of the world to fork, and optionally { name = "..." } to title the fork. It answers the new world's record with forked_from; zeromind.swap opens the fork in this engine.
