How do I map Campaign Monitor statuses to Salesforce campaign member statuses?

The Salesforce campaign member status value can be mapped to values coming from Campaign Monitor, i.e. you could map the opened status from Campaign Monitor to a Salesforce status named registered. In addition to mapping the statuses, you can also determine which statuses count as a response from the customer. This relates to the Salesforce responded fields on the campaign (i.e. responses in campaign).
