+* Use text mode LTTng to control tracing
+
+The tracing can be controlled from a terminal by using the lttctl command (as
+root).
+
+Start tracing :
+
+lttctl -n trace -d -l /mnt/relayfs/ltt -t /tmp/trace
+
+Stop tracing and destroy trace channels :
+
+lttctl -n trace -R
+
+see lttctl --help for details.
+
+
+* Use text mode LTTV
+
+Fell free to look in /usr/local/lib/lttv/plugins to see all the text and
+graphical plugins available.
+
+For example, a simple trace dump in text format is available with :
+
+lttv -m textDump -t /tmp/trace
+
+see lttv -m textDump --help for detailed command line options of textDump.
