batch rendering multiple scenes using net render

Hi All,
I have a bunch of scenes created within a single project. I'm using net render. Within the net render interface, I simply select the scene file, set it to master, and render. I can't seem to find a way to batch render all of the scenes overnight? I keep everything in a single project so that I don't have to copy the textures for multiple projects. Is there an easy way to get all of the files to render without my interaction?
