Activity conventions?

[Kent Loobey]

Can someone point me to a list of the OLPC "Activity" conventions.

I just got my XO an hour or so ago and I have already noticed some 
inconsistencies in the way "activities" close/exit.

I want to make sure that the activities I write are consistent with the OLPC 
conventions.

I am writing in Python but I would think that the conventions would be 
universal but then ya never know.

Thanks.
