 634 Example:
 635 This command will add the context information 'prio' and two perf
 636 counters (hardware branch misses and cache misses), to all events

 664 usage: lttng add-context -t TYPE
 665
 666 If no channel and no event is given (-c/-e), the context
 667 will be added to all events and all channels.
 668 Otherwise the context will be added only to the channel (-c)
 669 and/or event (-e) indicated.
 670 Exactly one domain (-k/--kernel or -u/--userspace) must be specified.
