+Package webhooks provides information and interaction with the webhook API resource
+in the Rackspace Auto Scale service.
+
+Auto Scale uses webhooks to initiate scaling events. Webhooks are associated
+with scaling policies and provide capability URLs which can be accessed
+anonymously to trigger execution of those policies. The Auto Scale webhook
+architecture allows Auto Scale to be integrated with other systems, for example,
+monitoring systems.
