This set will be merged with all "package.hugo.json" files found in the dependency tree, picking the version closest to the project.
This command is marked as 'Experimental'. We think it's a great idea, so it's not likely to be
removed from Hugo, but we need to test this out in "real life" to get a feel of it,
so this may/will change in future versions of Hugo.
