-- Retrieves information about the specified role, including the role\'s
-- path, GUID, ARN, and the role\'s trust policy that grants permission to
-- assume the role. For more information about roles, see

--
-- 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.
