// An interface for managing organization policies.
//
// The Organization Policy Service provides a simple mechanism for
// organizations to restrict the allowed configurations across their entire
// resource hierarchy.
//
// You can use a policy to configure restrictions on resources. For
// example, you can enforce a policy that restricts which Google
// Cloud APIs can be activated in a certain part of your resource
// hierarchy, or prevents serial port access to VM instances in a
// particular folder.
//
// Policies are inherited down through the resource hierarchy. A policy
// applied to a parent resource automatically applies to all its child resources
// unless overridden with a policy lower in the hierarchy.
//
// A constraint defines an aspect of a resource's configuration that can be
// controlled by an organization's policy administrator. Policies are a
// collection of constraints that defines their allowable configuration on a
// particular resource and its child resources.
