+ * iofileb.d - I/O bytes by filename and process.
+ *             Written using DTrace (Solaris 10 3/05).
+ *
+ * This prints a summary of requested disk activity by pathname,
+ * providing totals of the I/O events in bytes. It is a companion to the
+ * iofile.d script - which prints in terms of I/O wait time, not bytes.
+ * I/O wait time is a better metric for understanding performance issues.
+ * Both disk and NFS I/O are measured.

+ *
+ * USAGE:	iofileb.d	# wait several seconds, then hit Ctrl-C
+ *
+ * FIELDS:
+ *		PID	process ID
+ *		CMD	command name
+ *		KB	Kilobytes of disk I/O
+ *		FILE	Full pathname of the file
