          Create a VMware Engine network. VMware Engine network creation is considered finished when the VMware Engine network is in ACTIVE state. Check the progress of a VMware Engine network creation using `{parent_command} list`.

        """
          To create a VMware Engine network of type `STANDARD`, run:

            $ {command} my-network --type=STANDARD --location=global --project=my-project

          Or:

            $ {command} my-network --type=STANDARD

          In the second example, the project is taken from gcloud properties core/project and the location is taken as `global`.

          To create a VMware Engine network of type `LEGACY` in the `us-west2` region, run:

            $ {command} my-network --type=LEGACY --location=us-west2 --project=my-project

          Or:

            $ {command} my-network --type=LEGACY --location=us-west2

          In the last example, the project is taken from gcloud properties core/project. For VMware Engine networks of type `LEGACY`, you must always specify a region as the location.
