org.apache.tools.ant.taskdefs.Manifest
public class Manifest
extends java.lang.Object
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.
