+// Package containers contains functionality for working with Object Storage
+// container resources. A container serves as a logical namespace for objects
+// that are placed inside it - an object with the same name in two different
+// containers represents two different objects.
+//
+// In addition to containing objects, you can also use the container to control
+// access to objects by using an access control list (ACL).
