+// to the v8 debugger. This class coordinates communication between the debug
+// agents and v8 debugger. It will set debug output handler as long as at least
+// one debugger agent is attached and remove it when last debugger agent is
+// detached. When message is received from debugger it will route it to the
+// right debugger agent if there is one otherwise the message will be ignored.
+//
+// v8 may send a message(e.g. exception event) after which it
+// would expect some actions from the handler. If there is no appropriate
+// debugger agent to handle such messages the manager will perform the action
+// itself, otherwise v8 may hang waiting for the action.
