+    # to have these messages end up in /var/log/haproxy.log you will
+    # need to:
+    #
+    # 1) configure syslog to accept network log events.  This is done
+    #    by adding the '-r' option to the SYSLOGD_OPTIONS in
+    #    /etc/sysconfig/syslog
+    #
+    # 2) configure local2 events to go to the /var/log/haproxy.log
+    #   file. A line like the following can be added to
+    #   /etc/sysconfig/syslog
+    #
+    #    local2.*                       /var/log/haproxy.log
