To use my script you need 3 things:
1) To log queries
2) To log into a file you can read with the script
3) DJBDNS so you have programs dnsip and dnsname.  I don't have the URL
handy but the site is cryp.to

In order to dump the cache to the file, issue
killall -USR1 dnsmasq
which I put into the rc.dnsmasq script so that a stop dumps the cache.

At the end of your dnsmasq.conf, add (or uncomment) a line

log-queries

I also change the logging to go to /var/log/DNSMasq

I posted this to dnsmasq-discuss on 2 June 2005:
By default, dnsmasq logs daemon.debug.  In /etc/syslog.conf look for
debug to
see which log file and where located.

I dislike daemon.debug so I changed src/config.h to configure logging as
local1.debug, then I added
local1.*        /var/log/DNSmasq
to the end of syslog.conf (and restarted the syslog daemon).

I don't have the original lines from config.h but here's what is there
now:
#ifdef LOG_LOCAL0
#  define DNSMASQ_LOG_FAC(debug)  (debug) ? LOG_DAEMON : LOG_LOCAL1
#else
#  define DNSMASQ_LOG_FAC(debug)  LOG_LOCAL1
#endif
