-"""Script to download sdk/extras packages on the bots from google storage.
-
-The script expects arguments that specify zips file in the google storage
-bucket named: <dir in SDK extras>_<package name>_<version>.zip. The file will
-be extracted in the android_tools/sdk/extras directory on the test bots. This
-script will not do anything for developers.
-
-TODO(navabi): Move this script (crbug.com/459819).
