Drawing vector graphics using a command line

[Douglas Pollard]

This is maybe off topic, But Linux CNC wil draw on screen almost 
anything you can think of and it comes in ubuntu.  I believe it can be 
run in camand line as well. I designed a couple boats and built them to 
sell.   Works great for some things.  Doug
