-# A script for testing imgdiff/applypatch. It takes two full OTA
-# packages as arguments. It generates (on the host) patches for all
-# the zip/jar/apk files they have in common, as well as boot and
-# recovery images. It then applies the patches on the device (or
-# emulator) and checks that the resulting file is correct.
