+SYNOPSIS
+        #include <sys/driver_hooks.h>
+
+        set_driver_hook(H_MOVE_OBJECT0, value)
+        set_driver_hook(H_MOVE_OBJECT1, value)
+
+        <value> being:
+
+          void <closure>(object item, object dest)
+
+DESCRIPTION
+        Mandatory hooks to implement the efun void move_object().
+        Hook setting must be an unbound lambda closure.
+
+        Upon call, the hook has to perform the move itself (by using
+        set_environment()) and all depending actions (like the calls to
+        init() to add actions).
+
+        The difference lies in the binding of the set hook prior to
+        the call: the H_MOVE_OBJECT0 closure is bound to the current
+        object, the H_MOVE_OBJECT1 to 'item'.
+        If both hooks are set, H_MOVE_OBJECT0 is ignored.
