-- Attaches the specified managed policy to the specified role.
--
-- When you attach a managed policy to a role, the managed policy is used
-- as the role\'s access (permissions) policy. You cannot use a managed
-- policy as the role\'s trust policy. The role\'s trust policy is created
-- at the same time as the role, using CreateRole. You can update a role\'s
-- trust policy using UpdateAssumeRolePolicy.
--
-- Use this API to attach a managed policy to a role. To embed an inline
-- policy in a role, use PutRolePolicy. For more 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 /Using IAM/ guide.
