+        - S3 URL endpoint. If not specified then the S3_URL environment variable is used, if that variable is defined. Ansible tries to guess if fakes3 (https://github.com/jubos/fake-s3) or Eucalyptus Walrus (https://github.com/eucalyptus/eucalyptus/wiki/Walrus) is used and configure connection accordingly. Current heuristic is: everything with scheme fakes3:// is fakes3, everything else not ending with amazonaws.com is Walrus.
