-- Lists the accounts in an organization that are contained by the
-- specified target root or organizational unit (OU). If you specify the
-- root, you get a list of all the accounts that aren\'t in any OU. If you
-- specify an OU, you get a list of all the accounts in only that OU and
-- not in any child OUs. To get a list of all accounts in the organization,
-- use the ListAccounts operation.
--
-- Always check the @NextToken@ response parameter for a @null@ value when
-- calling a @List*@ operation. These operations can occasionally return an
-- empty set of results even when there are more results available. The
-- @NextToken@ response parameter value is @null@ /only/ when there are no
-- more results to display.
--
-- This operation can be called only from the organization\'s management
-- account or by a member account that is a delegated administrator for an
-- Amazon Web Services service.
--
-- This operation returns paginated results.
