[Squeakland] Where can I find a description of make siblings

[stéphane ducasse]

hi

I was showing to a teacher how to use make siblings and we were 
confused by the behavior.
Is there somewhere a description of the difference between copy and 
make siblings.
Apparently the behavior (duplicate) changed between 3.6-3.7 and 3.8. in 
3.8 this is now make siblings by default.
I checked a bit and it seems that indeed all the siblings are sharing 
the same behavior and the variables are local to each object.

So one teacher asked me how to get back the default copy behavior I 
browsed in the halos menus but I could not find that anymore. So what 
is the status of the makesibling/copy behavior? Is copy simply 
deprecated (which makes sense to me).
