OAuth 2.0 Client Library

oauth2client is a Python library designed for interacting with OAuth 2.0 protected resources, primarily for Google APIs. As of version 4.1.0, the library is officially deprecated, with no new features planned and limited support. Users are strongly advised to migrate to `google-auth` and `oauthlib` for modern and actively maintained OAuth 2.0 client functionality. The current version is 4.1.3.
