Outdated doc for turtle in 1.03?

[V Berry <vberry@lirmm.fr>]

Can someone help me getting that damn turtle work?
I choosed Beginning Student as a language then added the
teachpack turtle.ss), then clicked on "Execute" and :
(turtles #)
doesn't work (though it's told so in the included documentation!)

(To be safe, I also choosed Full Scheme (graphical MrEd) ,
then Add Teachpack -> turtles.ss
and typed (require-library "turtles.ss" "graphics")
but the result is the same).

After some frustrating time I managed to figure out that the "turtle"
function
now (in 103) is waiting for two integers indicating the size of the area

where it appears.

However, "draw" and other commands doesn't seem to work,
I can't figure out what they expect now (some kind of object?) and how
many arguments.

Could someone send me quick help about that (or doc hopefully)?
Thanks a lot
