+=head1 NAME
+
+dar_cpuusage - Munin plugin to monitor darwin cpu usage.
+
+=head1 APPLICABLE SYSTEMS
+
+Should work on any darwin (Mac OS X) system with the 'top' command.
+
+=head1 CONFIGURATION
+
+None needed
+
+=head1 INTERPRETATION
+
+The plugin runs the top command and shows the CPU usage for the machine.
+
+=head1 BUGS
+
+The stats are a snapshot at the time of the command - a 5 minute average would
+be better.
+
+=head1 MAGIC MARKERS
+
+  #%# family=auto
+  #%# capabilities=autoconf
+
+=head1 VERSION
+
+  v.0.0.1
