-- Returns the current list of AWS services and a list of service
-- categories that applies to each one. You then use service names and
-- categories in your < CreateCase> requests. Each AWS service has its own
-- set of categories.
--
-- The service codes and category codes correspond to the values that are
-- displayed in the __Service__ and __Category__ drop-down lists on the AWS
-- Support Center
-- <https://console.aws.amazon.com/support/home#/case/create Create Case>
-- page. The values in those fields, however, do not necessarily match the
-- service codes and categories returned by the 'DescribeServices' request.
-- Always use the service codes and categories obtained programmatically.
-- This practice ensures that you always have the most recent set of
-- service and category codes.
