2. package: This directory contains the Google Play services SDK itself.
When downloaded via the Android SDK manager, it will be a complete maven,
repository with the different versions of the library. When the update
script downloads the library from our cloud storage, it is cleared.
3. source_prop: File created by the Android SDK manager that contains
the package information, such as the version info and the license.
4. license: File created by the update script. Contains the license accepted
by the user.
5. lib_zip_sha1: sha1 of the library that has been installed by the
update script. It is compared with the one required by the config file to
check if an update is necessary.
6. client_paths: The client library jars we care about. They are zipped
zipped together and uploaded to the cloud storage.
