-"""Update .bp and .mk files under test/vts-testcase/hal.
-
-Among .bp and .mk files affected are:
-1. test/vts-testcase/hal/Android.bp
-2. files matching: test/vts-testcase/hal/<hal_name>/<hal_version>/Android.bp
-
-Usage:
-  To update build files for all HALs:
-     cd test/vts-testcase/hal; ./script/update_makefiles.py
-  To update build files for a specific HAL:
-     cd test/vts-testcase/hal; ./script/update_makefiles.py --hal nfc@1.0
