The XML configuration file is usually contained in the polco.jar file in the config directory. The most important options can be controlled via runtime arguments ({@link ch.javasoft.polco.main.Polco#main(String[])} command line} version) or via {@link ch.javasoft.polco.adapter.Options Options} ({@link ch.javasoft.polco.adapter.PolcoAdapter PolcoAdapter} for use as library). Non-standard options can be changed in the XML configuration file.
