# 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
OPTIONS=""
