+NAME
+----
+perf-inject - Filter to augment the events stream with additional information
+
+SYNOPSIS
+--------
+[verse]
+'perf inject <options>'
+
+DESCRIPTION
+-----------
+perf-inject reads a perf-record event stream and repipes it to stdout.  At any
+point the processing code can inject other events into the event stream - in
+this case build-ids (-b option) are read and injected as needed into the event
+stream.
+
+Build-ids are just the first user of perf-inject - potentially anything that
+needs userspace processing to augment the events stream with additional
+information could make use of this facility.
+
+OPTIONS
+-------
+-b::
+--build-ids=::
+        Inject build-ids into the output stream
+-v::
+--verbose::
+       Be more verbose.
+-i::
+--input=::
+       Input file name. (default: stdin)
+-o::
+--output=::
+       Output file name. (default: stdout)
+-s::
+--sched-stat::
+       Merge sched_stat and sched_switch for getting events where and how long
+       tasks slept. sched_switch contains a callchain where a task slept and
+       sched_stat contains a timeslice how long a task slept.
+
+--kallsyms=<file>::
+       kallsyms pathname
