+    ---help---
+      Enables a hypercall for domains to ask the hypervisor to perform
+      data transfer of messages between domains.
+
+      This allows communication channels to be established that do not
+      require any shared memory between domains; the hypervisor is the
+      entity that each domain interacts with. The hypervisor is able to
+      enforce Mandatory Access Control policy over the communication.
+
+      If XSM_FLASK is enabled, XSM policy can govern which domains may
+      communicate via the Argo system.
+
+      This feature does nothing if the "argo" boot parameter is not present.
+      Argo is disabled at runtime by default.
