title: Inkscape command line programming
body: <p>I'd like to be able to derive new images from a pre-existing image from the command line. To do that, I'd turn on/off specific layers that have portions of the image and then save the resulting image to a file.  However, while I can see a number of commands listed in the help to manipulate layers, I don't see any that would allow one to select a specific one and turn it on/off.</p>
