        access key ID that you have just generated.

    --bucket <bucket>
        You must provide a valid S3 bucket name that you want media files to be
        uploaded to.

    --region <region>
        You must provide a valid S3 region. As 2016-03-17, S3 has the following
        regions:

        us-east-1
        us-west-1
        us-west-2
        eu-west-1
        eu-central-1
        ap-southeast-1
        ap-southeast-2
        ap-northeast-1
        ap-northeast-2
        sa-east-1

        You can review all valid S3 regions via the AWS documentation
        (http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region).
