8SYNOPSIS
9--------
10[verse]
11'perf inject <options>'

13DESCRIPTION
14-----------
15perf-inject reads a perf-record event stream and repipes it to stdout.  At any
16point the processing code can inject other events into the event stream - in
17this case build-ids (-b option) are read and injected as needed into the event
18stream.
19
20Build-ids are just the first user of perf-inject - potentially anything that
21needs userspace processing to augment the events stream with additional
22information could make use of this facility.
