basic question - looking for a script to understand

I am trying to accomplish this ..

For my program, I have 3 exe files each of which have installers and a DLL which needs to be registered.

All of these have to go as a package under one setup.exe file.
I need some example script or any pointers to where i could find related information for this. I tried FAQ and wiki pages and example scripts but could not find something definitive.

THanks

I'm pretty sure the combination of FAQ, examples, Help file and wiki are all you need to accomplish.

I think the ${NSISDIR}\examples\example1.nsi is one way to start
