+Comparing two bootcharts
+------------------------
+A handy script named compare-bootcharts.py can be used to compare the
+start/end time of selected processes. The aforementioned grab-bootchart.sh
+will leave a bootchart tarball named bootchart.tgz at /tmp/android-bootchart.
+If two such barballs are preserved on the host machine under different
+directories, the script can list the timestamps differences. For example:
