public class Concat extends Task implements ResourceCollection
This class contains the 'concat' task, used to concatenate a series of files into a single stream. The destination of this stream may be the system console, or a file. The following is a sample invocation: 
 <concat destfile="${build.dir}/index.xml"
   append="false">

   <fileset dir="${xml.root.dir}"
     includes="*.xml" />

 </concat>
