   9 # igmpproxy supports both a debug mode and verbosity, which are very useful
  10 # when something isn't working.
  11 #
  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.
  14 #
  15 # Put any debug or verbosity options into IGMP_OPTS
  16 #
  17 # Examples:
  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
  21
