<h2><a name="jarlib-manifest">jarlib-manifest</a></h2>
<h3>Description</h3>
<p>Task to generate a manifest that declares all the dependencies
 in manifest. The dependencies are determined by looking in the
 specified path and searching for Extension / "Optional Package"
 specifications in the manifests of the jars.</p>

<p>Note that this task
works with extensions as defined by the "Optional Package" specification.
 For more information about optional packages, see the document
<em>Optional Package Versioning</em> in the documentation bundle for your
Java2 Standard Edition package, in file
<code>guide/extensions/versioning.html</code> or online at
<a href="http://java.sun.com/j2se/1.3/docs/guide/extensions/versioning.html">
http://java.sun.com/j2se/1.3/docs/guide/extensions/versioning.html</a>.</p>
<p>See the Extension and ExtensionSet documentation for further details</p>
