    The following script shows a little more complicted jruby example:
  </p>
  <blockquote><pre>
 &lt;script language="ruby"&gt;
  xmlfiles = Dir.new(".").entries.delete_if { |i| ! (i =~ /\.xml$/) }
  xmlfiles.sort.each { |i| $self.log(i) }

  <p>
    Note that due to a limitation in the current version of jruby (0.7.0),
    $project.log("Hello World") does not work (most likely because there are
    two log methods on Project), this is fixed in the current CVS version of jruby.

    The same example in groovy is:
  </p>
  <blockquote><pre>
 &lt;script language="groovy"&gt;
  xmlfiles = new java.io.File(".").listFiles().findAll{ it =~ "\.xml$"}
  xmlfiles.sort().each { self.log(it.toString())}

    The following script uses javascript to create a number of
    echo tasks and execute them.
