  The first header type is the "Event" header.  Other headers vary from
  event to event.  Headers end with standard \r\n termination.
+ The last line of the manager response or event is an empty line.
+ (\r\n)
  
- Some standard headers:
-
- Action: <action>		-- request or notification of a particular action
- Response: <response>		-- response code, like "200 OK"
+ ** Please try to re-use existing headers to simplify manager message parsing in clients.
+    Don't re-use an existing header with a new meaning, please.
+    You can find a reference of standard headers in
+    doc/manager.txt
