"""Make boto3 automatically check the shared credentials file for updates.

In some situations, the ~/.aws/credentials file may be periodically updated. For
example, this is the case with the "AWS managed temporary credentials" which are
provided to AWS Cloud9 environments. (See
<https://docs.aws.amazon.com/cloud9/latest/user-guide/how-cloud9-with-iam.html#auth-and-access-control-temporary-managed-credentials>.)

Example usage of this module is:

import boto3
