+ * rb_stat.d - Ruby operation stats using DTrace.
+ *             Written for the Ruby DTrace provider.
+ *
+ * $Id: rb_stat.d 20 2007-09-12 09:28:22Z brendan $
+ *
+ * This traces activity from all Ruby programs on the system that are
+ * running with Ruby provider support.
+ *
+ * USAGE: rb_stat.d [interval [count]]
+ *
+ * FIELDS:
+ *		EXEC/s		Ruby programs executed per second, including
+ *				those without Ruby provider support
+ *		METHOD/s	Methods called, per second
+ *		OBJNEW/s	Objects created, per second
+ *		OBJFRE/s	Objects freed, per second
+ *		RAIS/s		Raises, per second
+ *		RESC/s		Rescues, per second
+ *		GC/s		Garbage collects, per second
+ *
+ * The numbers are counts for the interval specified. The default interval
+ * is 1 second.
+ *
+ * If you see a count in "EXECS" but not in the other columns, then your
+ * Ruby software is probably not running with the DTrace Ruby provider.
+ * See Ruby/Readme.
+ *
+ * Filename and method names are printed if available.
