-- Retrieves the specified inline policy document that is embedded in the
-- specified IAM user.
--
-- Policies returned by this operation are URL-encoded compliant with
-- <https://tools.ietf.org/html/rfc3986 RFC 3986>. You can use a URL
-- decoding method to convert the policy back to plain JSON text. For
-- example, if you use Java, you can use the @decode@ method of the
-- @java.net.URLDecoder@ utility class in the Java SDK. Other languages and
-- SDKs provide similar functionality.
--
-- An IAM user can also have managed policies attached to it. To retrieve a
-- managed policy document that is attached to a user, use GetPolicy to
-- determine the policy\'s default version. Then use GetPolicyVersion to
-- retrieve the policy document.
--
-- For more information about policies, see
-- <https://docs.aws.amazon.com/IAM/latest/UserGuide/policies-managed-vs-inline.html Managed policies and inline policies>
-- in the /IAM User Guide/.
