+/*
+Package gophercloud provides a multi-vendor interface to OpenStack-compatible
+clouds. The library has a three-level hierarchy: providers, services, and
+resources.
+
+Provider structs represent the service providers that offer and manage a
+collection of services. Examples of providers include: OpenStack, Rackspace,
+HP. These are defined like so:
+
+ opts := gophercloud.AuthOptions{
+ IdentityEndpoint: "https://my-openstack.com:5000/v2.0",
+ Username: "{username}",
+ Password: "{password}",
+ TenantID: "{tenant_id}",
+ }
+
+ provider, err := openstack.AuthenticatedClient(opts)
+
+Service structs are specific to a provider and handle all of the logic and
+operations for a particular OpenStack service. Examples of services include:
+Compute, Object Storage, Block Storage. In order to define one, you need to
+pass in the parent provider, like so:
+
+ opts := gophercloud.EndpointOpts{Region: "RegionOne"}
+
+ client := openstack.NewComputeV2(provider, opts)
+
+Resource structs are the domain models that services make use of in order
+to work with and represent the state of API resources:
+
+ server, err := servers.Get(client, "{serverId}").Extract()
+
+Another convention is to return Result structs for API operations, which allow
+you to access the HTTP headers, response body, and associated errors with the
+network transaction. To get a resource struct, you then call the Extract
+method which is chained to the response.
