[Dnsmasq-discuss] Are dnsmasq's dhcp-option accumulative

[T o n g]

Hi, 

Are dnsmasq's dhcp-option accumulative?

I notice the following two lines in different files from /etc/dnsmasq.d/
dnsmasq.*.conf

  dhcp-option=option:router,192.168.2.1
  dhcp-option=6,0.0.0.0

Are they one overwrite another or they are accumulative? I.e., if I put 
in another file:

  dhcp-option=252,"http://192.168.1.2/wpad.dat"

All three will take effect at the same time, right? 

Thanks
