+ * loads.d - print load averages. Written using DTrace (Solaris 10 3/05).
+ *
+ * These are the same load averages that the "uptime" command prints.
+ * The purpose of this script is to demonstrate fetching these values
+ * from the DTrace language.
+ *
+ * $Id: loads.d 3 2007-08-01 10:50:08Z brendan $
+ *
+ * USAGE:	loads.d
+ *
+ * SEE ALSO:	uptime(1)
+ *
+ * The first field is the 1 minute average, the second is the 5 minute,
+ * and the third is the 15 minute average. The value represents the average
+ * number of runnable threads in the system, a value higher than your
+ * CPU (core/hwthread) count may be a sign of CPU saturation.
