Help in deciphering config rules..

[Ishwar Rattan <ishwar () pali cps cmich edu>]

Just got interested in honeyd. I found sample config files
on www.honeyd.org. I understand the route stuff but have a
little problem with info like:
...
add default udp port 53 "./scripts/dnstool.py"
add default tcp port 25 "scripts/smtp.pl -n <youremailaddresshere>"
add default tcp port 80 "./scripts/iis5.net/main.pl"
...

On first line with add: "./scripts/dnstool.py" -- I assume it is a
python script. Where does it come from? Do I have to write onea? If so,
what goes in there (a sample will help)?

Thanks for your time.
