Hey, I've set up a script to render a half a dozen cameras through terminal. But many of the shots require a variety of different Display and Render Layers to be activated. 

Maya is telling me that I can use the option "-l boolean|name(s)" to "select which display and render layers to render" 
I'm tired and confused. Would anyone be so kind to post an example, so I can work out the correct syntax?
