/**
 The EventJar task automates the construction of an event jar file that may
 be included in a deployable unit jar.
 <pre>
 <event destfile="pathname.jar" eventjarxml="foo/bar/event-jar.xml" autoinclude="yes" classpath="...">
    <classpath ...>
    <fileset ... >
 </event>
 </pre>
 eventjarxml is assumed to have a default value of event-jar.xml, so this property may be ommited if
 the metatinfbase property is used or inherited from an enclosing deployableunit task.
