             <ulink url="http://wrapper.tanukisoftware.org/">Java Service Wrapper</ulink>
             product from Tanuki Software to run in the background as a Unix system service.

             so it can be easily identified from a list of running processes.
             The service configuration is found in <filename class="filename">conf/sym_service.conf</filename>.
