 The package exports the `Pathy` class and utilities for configuring the bucket storage provider to use. By default Pathy prefers GoogleCloudStorage paths of the form `gs://bucket_name/folder/blob_name.txt`. Internally Pathy can convert GCS paths to local files, allowing for a nice developer experience.

-from pathy import Pathy
