+# This is the install script for generating an Android image based off the
+# current working build tree. make is called to relink the object files and
+# generate the new Android image to be flashed. The device is then rebooted into
+# bootloader mode and fastboot is used to flash the new image. The device is
+# then rebooted so the user's test script can run.
+#
+# This script is intended to be used by binary_search_state.py, as
+# part of the binary search triage on the Android source tree. It should
+# return '0' if the install succeeds; and '1' if the install fails (the image
+# could not build or be flashed).
