[Dnsmasq-discuss] Pulling DHCP leases from an external script?

I'm not 100% certain, but the way I read the man page, the script is
triggered after the dnsmasq event occurs, so you can pass some custom
behavior to a script after dnsmasq has managed the lease.  However, it
sounds like you want to customize dnsmasq behavior and insert your own
algorithm for allocating IP addresses?  Just out of curiosity, why?  You
can specify quite a complex set of allocation rules using tags and more,
why would you need to have anything other than that?
