Command Line Invocation of RR - Sort of works

Hi

I'd like to find out if there are any additional parameters that RR can take at the command line
level to make my life easier at scripting the rendering process. This is what I have so far:

/Applications/RaceRender\ 3.app/Contents/MacOS/RaceRender\ 3 outdoor.rrp

I'm on a Mac but that shouldn't matter (much). The above line launches RR directly
into the project file. It isn't much, but it's still a timesaver.

Anyone else work along these lines that may have some info to share?
