+ * rwbypid.d - read/write calls by PID.
+ *             Written using DTrace (Solaris 10 3/05)
+ *
+ * This script tracks the number of reads and writes at the syscall level
+ * by processes, printing the totals in a report. This matches reads
+ * and writes whether they succeed or not.
+ *
+ * $Id: rwbypid.d 3 2007-08-01 10:50:08Z brendan $
+ *
+ * USAGE:	rwbypid.d			# hit Ctrl-C to end sample
+ *
+ * FIELDS:
+ *		PID		process ID
+ *		CMD		process name
+ *		DIR		Read or Write
+ *		COUNT		total calls
