+Flower is a label-based networking daemon.
+
+CloudABI applications are not permitted to call bind or connect on
+sockets directly, as that would conflict with CloudABI's security model.
+Instead, they can send RPCs to fulfill such requests to a separate
+daemon, called Flower.
+
+Like CloudABI, Flower makes use of a capability-based security model.
+This makes it easy to spawn applications in such a way that they can
+only have a limited view of the network, without requiring separate
+users or complex access control policies.
