44 <p>The final steps in producing a Blitz distribution are to create the <code>blitz.jar</code>, <code>blitz-dl.jar</code> and <code>stats.jar</code> files. By convention, building <code>blitz-dl.jar</code> entails including all classes the Blitz proxy code is dependent upon including various classes of the JINI starter kit.</p>

46 <p>Fortunately, there is an Ant addon task which makes the work of generating the dependencies and building a .jar trivial. The necessary .jar is included in <code>ant_addon</code> and automatically used by the <code>build.xml</code> file (there's no need to install the addon in the Ant lib directory).</p>
