# tool -- project homepage is at http://munin.sourceforge.net/

# This package has added support for NetBSD, via a number of new plugin
# scripts where specific steps needs to be taken to collect information.
#
# I also modified the ntp_ plugin script to make it possible to not
# plot the NTP poll delay, leaving just jitter and offset, which IMO
# produces a more telling graph.
#
#
#
# Magic markers (optional - only used by munin-config and some
# installation scripts):

#%# capabilities=autoconf
