<h2><a name="signjar">SignJar</a></h2>
<h3>Description</h3>
<p>Signs JAR files with the <tt>jarsigner</tt> command line tool. 
It will take a named file in the <tt>jar</tt> attribute, and an optional
<tt>destDir</tt> or <tt>signedJar</tt> attribute. Nested filesets are also
supported; here only an (optional) <tt>destDir</tt> is allowed. If a destination
directory or explicit JAR file name is not provided, JARs are signed in place.
</p>
<p>
Dependency rules
</p>
<ul>
<li>Nonexist destination JARs are created/signed</li>
<li>Out of date destination JARs are created/signed</li>
<li>If a destination file and a source file are the same,
and <tt>lazy</tt> is true, the JAR is only signed if it does not 
contain any signature.</li> 
<li>If a destination file and a source file are the same,
and <tt>lazy</tt> is false, the JAR is signed.</li> 
</ul>

<p>
When checking signatures, the actual signatory itself is not verified. This
means that "lazy" checks do not work if a JAR is signed by multiple authors.
</p>
