Who said anything about parameters? If you meant arguments then indeed, OS X 
provides 2 ways to hand of arguments that correspond to documents (files) to 
open. The standard argc,argv way and something that is a lot like DBus messages.
But that's not the point here.

It's a little bit more subtle than that, and if you look at qprocess_unix.cpp 
you'll see a bit of code that does the opposite when it encounters an app 

But what you're basically saying is that if QProcess cannot do the job for us, 
we just have to use something other than Qt?
