[Zope] Mac OS X SystemStarter interface

I am new to this but I have not seen how the "runzope" or zopectl start commands are done at system startup. Mac OS X has its own system(s). The old is called SystemStarter and the new is called launchd. SystemStarter requires a directory and a few simple files. I'm not sure what launchd requires. Is there a need to implement these or has it already been done? How do most people do it on the various unix/linux versions? If not, I'll take a swag at it if others feel they could use it.
