13 DESCRIPTION
14 -----------
15 perf-inject reads a perf-record event stream a
16 point the processing code can inject other eve
17 this case build-ids (-b option) are read and i
18 stream.
19
20 Build-ids are just the first user of perf-inje
21 needs userspace processing to augment the even
22 information could make use of this facility.
