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