 swift via the Amazon S3 API.

+ - Support Bucket APIs (GET/PUT/DELETE/HEAD)
+ - Support Object APIs (GET/PUT/DELETE/HEAD)
+ - Support Multipart Upload (required **SLO** middleware support)
+ - Support S3 ACL (**under development**)

+    # information via Swift API at all and the acl won't be applied against to
+    # Swift API even if it is for a bucket currently supported.)
