#
# 24.11.2009 Version 1.1 added support for multiple tuners
# 22.11.2009 Version 1.0 added check that femon iinstalled
# 21.11.2009 Version 0.9 added adapter number
# 20.11.2009 Version 0.8 first version
#
# Magic markers (optional):
#%# family=auto
#%# capabilities=autoconf suggest
#Change this value to point to the tuner you want to watch
Tuner=1
#Starting point for tuner to watch
