+"""Record the event logs during boot and output them to a file.
+
+This script repeats the record of each event log during Android boot specified
+times. By default, interval between measurements is adjusted in such a way that
+CPUs are cooled down sufficiently to avoid boot time slowdown caused by CPU
+thermal throttling. The result is output in a tab-separated value format.
+
+Examples:
+
+Repeat measurements 10 times. Interval between iterations is adjusted based on
+CPU temperature of the device.
+
+$ ./perfboot.py --iterations=10
+
+Repeat measurements 20 times. 60 seconds interval is taken between each
+iteration.
+
+$ ./perfboot.py --iterations=20 --interval=60
+
+Repeat measurements 20 times, show verbose output, output the result to
+data.tsv, and read event tags from eventtags.txt.
+
+$ ./perfboot.py --iterations=30 -v --output=data.tsv --tags=eventtags.txt

+Systrace
+--------
+Systrace [1] can be used for obtaining performance analysis reports during boot
+time on userdebug or eng builds.
+Here is an example of trace events of "wm" and "am" categories:
+
+  $ANDROID_BUILD_TOP/external/chromium-trace/systrace.py wm am --boot
+
+This command will cause the device to reboot. After the device is rebooted and
+the boot sequence has finished, the trace report is obtained from the device
+and written as trace.html on the host by hitting Ctrl+C.
+
+LIMITATION
+Recording trace events is started after persistent properties are loaded, so
+the trace events that are emitted before that are not recorded. Several
+services such as vold, surfaceflinger, and servicemanager are affected by this
+limitation since they are started before persistent properties are loaded.
+Zygote initialization and the processes that are forked from the zygote are not
+affected.
