Automation of ZFS65 install and SP2 install

Hi All ;-),
Got a question about automating the install of ZSM65 and ZSM65sp2

We are still in our rollout phase and have another 300 servers to rollout
ZSM to. We were wondering if there was a way to automate the install of
ZSM65, and if possible the SP2.
I have built template files to help with the GUI install, but I wondered
if there was a way to pass the setup.exe file a properties file and if so
how would we build the properties file ;-)
Thanks for all your help with this one.
