+// Package configurations provides information and interaction with the
+// configuration API resource in the Rackspace Database service.
+//
+// A configuration group is a collection of key/value pairs which define how a
+// particular database operates. These key/value pairs are specific to each
+// datastore type and serve like settings. Some directives are capable of being
+// applied dynamically, while other directives require a server restart to take
+// effect. The configuration group can be applied to an instance at creation or
+// applied to an existing instance to modify the behavior of the running
+// datastore on the instance.
