Examples of java.util.jar.Manifest

java.util.jar.Manifest
The Manifest class is used to maintain Manifest entry names and their associated Attributes. There are main Manifest Attributes as well as per-entry Attributes. For information on the Manifest format, please see the Manifest format specification. @author David Connelly @version 1.50, 04/21/06 @see Attributes @since 1.2
