+ * j_calldist.d - measure Java elapsed times for different types of operation.
+ *                Written for the Java hotspot DTrace provider.
+ *
+ * $Id: j_calldist.d 59 2007-10-03 08:21:58Z brendan $
+ *
+ * This traces activity from all Java processes on the system with hotspot
+ * provider support (1.6.0). Method calls are only visible when using the
+ * flag "+ExtendedDTraceProbes". eg, java -XX:+ExtendedDTraceProbes classfile
+ *
+ * USAGE: j_calldist.d [top]	# hit Ctrl-C to end
+ *
+ * The "top" optional argument will truncate the output for each report
+ * section to that many lines, with a default of 10.
+ *
+ * FIELDS:
+ *		1		Process ID
+ *		2		Type of call (method/gc)
+ *		3		Name of call
