Due 11:59pm Wednesday, February 20
update37
Run update37 to download the skeleton file (graphics.scm) for your homework. This file, along with README.scm and structures.scm will be placed in your cs37/homework/04 directory. Be sure to read README.scm before beginning with graphics.scm.

Submit
Once you are satisfied with your programs, hand them in by typing handin37 at the unix prompt. You may run handin37 as many times as you like, and only the most recent submission will be recorded. This is useful if you realize after handing in some programs that you'd like to make a few more changes to them.
