To add support for the output from other programs, I'd need some simple samples to test them with. I don't have Illustrator, so I don't have a way of knowing what it's output is like in order to adjust the parser to support it. GIMP is what I have and use. The big three alternatives people might have and use are Illustrator, Inkscape, and Photoshop. Would be nice to have simple source files for those, and instructions on how to generate them for people that want to.
