java.lang.Object org.apache.tools.ant.taskdefs.Manifest
public class Manifest
Holds the data of a jar manifest. Manifests are processed according to the Jar file specification.. Specifically, a manifest element consists of a set of attributes and sections. These sections in turn may contain attributes. Note in particular that this may result in manifest lines greater than 72 bytes being wrapped and continued on the next line. If an application can not handle the continuation mechanism, it is a defect in the application, not this task.
