+// Declares an API to be included in this API. The including API must
+// redeclare all the methods from the included API, but documentation
+// and options are inherited as follows:
+//
+// - If after comment and whitespace stripping, the documentation
+//   string of the redeclared method is empty, it will be inherited
+//   from the original method.
+//
+// - Each annotation belonging to the service config (http,
+//   visibility) which is not set in the redeclared method will be
+//   inherited.
+//
+// - If an http annotation is inherited, the path pattern will be
+//   modified as follows. Any version prefix will be replaced by the
+//   version of the including API plus the [root][] path if specified.
+//
+// Example of a simple mixin:
+//
+//     package google.acl.v1;
+//     service AccessControl {
+//       // Get the underlying ACL object.
+//       rpc GetAcl(GetAclRequest) returns (Acl) {
+//         option (google.api.http).get = "/v1/{resource=**}:getAcl";
+//       }
+//     }
+//
+//     package google.storage.v2;
+//     service Storage {
+//       rpc GetAcl(GetAclRequest) returns (Acl);
+//
+//       // Get a data record.
+//       rpc GetData(GetDataRequest) returns (Data) {
+//         option (google.api.http).get = "/v2/{resource=**}";
+//       }
+//     }
+//
+// Example of a mixin configuration:
+//
+//     apis:
+//     - name: google.storage.v2.Storage
+//       mixins:
+//       - name: google.acl.v1.AccessControl
+//
+// The mixin construct implies that all methods in `AccessControl` are
+// also declared with same name and request/response types in
+// `Storage`. A documentation generator or annotation processor will
+// see the effective `Storage.GetAcl` method after inherting
+// documentation and annotations as follows:
+//
+//     service Storage {
+//       // Get the underlying ACL object.
+//       rpc GetAcl(GetAclRequest) returns (Acl) {
+//         option (google.api.http).get = "/v2/{resource=**}:getAcl";
+//       }
+//       ...
+//     }
+//
+// Note how the version in the path pattern changed from `v1` to `v2`.
+//
+// If the `root` field in the mixin is specified, it should be a
+// relative path under which inherited HTTP paths are placed. Example:
+//
+//     apis:
+//     - name: google.storage.v2.Storage
+//       mixins:
+//       - name: google.acl.v1.AccessControl
+//         root: acls
+//
+// This implies the following inherited HTTP annotation:
+//
+//     service Storage {
+//       // Get the underlying ACL object.
+//       rpc GetAcl(GetAclRequest) returns (Acl) {
+//         option (google.api.http).get = "/v2/acls/{resource=**}:getAcl";
+//       }
+//       ...
+//     }
