gcs-oauth2-boto-plugin is a Python application whose purpose is to behave
as an auth plugin for the boto auth plugin framework for use with OAuth 2.0
credentials for the Google Cloud Platform. This plugin is compatible with
both user accounts and service accounts, and its functionality is essentially
a wrapper around the oauth2client package of google-api-python-client with
the addition of automatically caching tokens for the machine in a thread-
and process-safe fashion.
