+/*
+ * j_who.d - trace Java calls by process using DTrace.
+ *           Written for the Java hotspot DTrace provider.
+ *
+ * $Id: j_who.d 19 2007-09-12 07:47:59Z brendan $
+ *
+ * This traces activity from all Java processes on the system with hotspot
+ * provider support (1.6.0).
+ *
+ * USAGE: j_who.d 		# hit Ctrl-C to end
+ *
+ * FIELDS:
+ *		PID		Process ID of Java
+ *		UID		User ID of the owner
+ *		CALLS		Number of calls made (a measure of activity)
+ *		ARGS		Process name and arguments
+ *
+ * The argument list is truncated at 55 characters (up to 80 is easily
+ * available). To easily read the full argument list, use other system tools;
+ * on Solaris use "pargs PID".
