The following is a demonstration of the dnlcsnoop.d script.
Here we run dnlcsnoop.d, while in another window a "find /etc/default"
command is executed,
# dnlcsnoop.d

The DNLC is the Directory Name Lookup Cache. Here we can see name lookups,
and whether the cache returned a hit. "/export/home/root/CacheKit-0.93" was
looked up a few times - this was the current directory that the find
command was executed from.
