# Revision 0.1 2008/08/23 13:06:00 joti

# First version only chronyc tracking, autodetection included.

# Revision 0.2 2008/10/11 16:09:00 joti

# Added scaling of other values to match with frequency, added more description to fields

# Magic markers (optional - used by munin-config and installation

# scripts):
