+# igmpproxy supports both a debug mode and verbosity, which are very useful
+# when something isn't working.
+#
+# Debug mode will print everything to stdout instead of syslog. Generally
+# verbosity should NOT be set as it will quickly fill your syslog.
+#
+# Put any debug or verbosity options into IGMP_OPTS
+#
+# Examples:
+# OPTIONS="-d -v -v" - debug mode and very verbose, this will land in
+#                        stdout and not in syslog
+# OPTIONS="-v" - be verbose, this will write aditional information to syslog
