-- Adds (or updates) an inline policy document that is embedded in the
-- specified role.
--
-- When you embed an inline policy in a role, the inline policy is used as
-- the role\'s access (permissions) 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. For more information
-- about roles, go to
-- <http://docs.aws.amazon.com/IAM/latest/UserGuide/roles-toplevel.html Using Roles to Delegate Permissions and Federate Identities>.
--
-- A role can also have a managed policy attached to it. To attach a
-- managed policy to a role, use AttachRolePolicy. To create a new managed
-- policy, use CreatePolicy. 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 /Using IAM/ guide.
--
-- For information about limits on the number of inline policies that you
-- can embed with a role, see
-- <http://docs.aws.amazon.com/IAM/latest/UserGuide/LimitationsOnEntities.html Limitations on IAM Entities>
-- in the /Using IAM/ guide.
--
-- Because policy documents can be large, you should use POST rather than
-- GET when calling 'PutRolePolicy'. For general information about using
-- the Query API with IAM, go to
-- <http://docs.aws.amazon.com/IAM/latest/UserGuide/IAM_UsingQueryAPI.html Making Query Requests>
-- in the /Using IAM/ guide.
