+II. Working with fbtracemgr :
 
 a) Start user trace named "My trace" using configuration file fbtrace.conf and read
    its output on the screen :
 
-	fbsvcmgr service_mgr action_trace_start trc_name "My trace" trc_cfg fbtrace.conf
+	fbtracemgr -se service_mgr -start -name "My trace" -config fbtrace.conf
 	
-	To stop this trace session press Ctrl+C at fbsvcmgr console window. Or, in
-another console : list sessions and look for interesting session ID (b) and stop
-it using this found ID (e).

 b) List trace sesions
 
-	fbsvcmgr service_mgr action_trace_list

 c) Suspend trace sesson with ID 1
 
-	fbsvcmgr service_mgr action_trace_suspend trc_id 1
+	fbtracemgr -se service_mgr -suspend -id 1
 	
 d) Resume trace sesson with ID 1
 
-	fbsvcmgr service_mgr action_trace_resume trc_id 1
+	fbtracemgr -se service_mgr -resume -id 1
