-- Retrieves information about the AWS Directory Service directories in the
-- region that are registered with Amazon WorkSpaces and are available to
-- your account.
--
-- This operation supports pagination with the use of the 'NextToken'
-- request and response parameters. If more results are available, the
-- 'NextToken' response member contains a token that you pass in the next
-- call to this operation to retrieve the next set of items.
