<h2><a name="signjar">SignJar</a></h2>
<h3>Description</h3>
<p>Signs jar or zip files with the javasign command line tool. The
tool detailed dependency checking: files are only signed if they
are not signed. The <tt>signjar</tt> attribute can point to the file to
generate; if this file exists then
its modification date is used as a cue as to whether to resign any JAR file.
