 NAME
 ----
-perf-sched - Read perf.data (created by perf record) and display sched output
+perf-sched - Tool to trace/measure scheduler properties (latencies)
 
 SYNOPSIS
 --------
 [verse]
-'perf sched' [-i <file> | --input=file] symbol_name
+'perf sched' {record|latency|replay|trace}
 
 DESCRIPTION
 -----------
-This command reads the input file and displays the latencies recorded.
+There's four variants of perf sched:
+
+  'perf sched record <command>' to record the scheduling events
+  of an arbitrary workload.
+
+  'perf sched latency' to report the per task scheduling latencies
+  and other scheduling properties of the workload.
+
+  'perf sched trace' to see a detailed trace of the workload that
+  was recorded.
+
+  'perf sched replay' to simulate the workload that was recorded
+  via perf sched record. (this is done by starting up mockup threads
+  that mimic the workload based on the events in the trace. These
+  threads can then replay the timings (CPU runtime and sleep patterns)
+  of the workload as it occured when it was recorded - and can repeat
+  it a number of times, measuring its performance.)
