+#  perf script | ./stackcollapse-perf.pl > out.stacks-folded
+#
+# The output of "perf script" should include stack traces. If these are missing

+#
+#  perf script -f comm,pid,tid,cpu,time,event,ip,sym,dso,trace | ...
+#
+# This is also required for the --pid or --tid options, so that the output has
