-- Lists all managed policies that are attached to the specified user.
--
-- A user can also have inline policies embedded with it. To list the
-- inline policies for a user, use the ListUserPolicies API. For
-- information about policies, refer to
-- <http://docs.aws.amazon.com/IAM/latest/UserGuide/policies-managed-vs-inline.html Managed Policies and Inline Policies>
-- in the /IAM User Guide/.
--
-- You can paginate the results using the 'MaxItems' and 'Marker'
-- parameters. You can use the 'PathPrefix' parameter to limit the list of
-- policies to only those matching the specified path prefix. If there are
-- no policies attached to the specified group (or none that match the
-- specified path prefix), the action returns an empty list.
