Having written my first bit of MrEd GUI code just last week, I can
attest that it is not difficult to get a basic grasp on it. I worked
from the MrEd Graphical Toolbox Manual, with reference to the class.ss
documentation (in the MzScheme Libraries Manual) as I needed it. It
was a lot of fun. (I know, I need to get out more.) --PR
