from compressor.cache import get_offline_manifest_filename
from storages.backends.s3boto import S3BotoStorage
class StaticCachedS3BotoStorage(S3BotoStorage):
S3 storage backend that also saves files locally for django-compressor
and also reads the manifest file from the local file-system instead of
S3, so packaged deploys also point to their own manifest.
