+ * dnlcps.d - DNLC stats by process.
+ *            Written in DTrace (Solaris 10 3/05).
+ *
+ * The DNLC is the Directory Name Lookup Cache. Filename lookups often
+ * return a hit from here, before needing to traverse the regular file
+ * system cache or go to disk.
+ *
+ * dnlcps.d prints DNLC statistics by process.

+ * USAGE:	dnlcps.d        # wait several seconds, then hit Ctrl-C
+ *
+ * FIELDS:
+ *		PID             Process ID
+ *		CMD          	Command name
+ *		value        	0 == miss, 1 == hit
+ *		count        	number of occurrences
