+* Mon Dec 12 2011 Joseph D. Wagner <joe@josephdwagner.info> 0:7.0.23-2
+- Added support to /usr/sbin/tomcat-sysd and /usr/sbin/tomcat for
+  starting tomcat with jsvc, which allows tomcat to perform some
+  privileged operations (e.g. bind to a port < 1024) and then switch
+  identity to a non-privileged user. Must add USE_JSVC="true" to
+  /etc/tomcat/tomcat.conf or /etc/sysconfig/tomcat.
