[Sugar-devel] Help Needed adding a module to my Activity

Hi, Sam

My understanding is that activities need to satisfy their own 
dependencies. This helps minimize the space taken by Sugar providing 
software for activities
not installed. Currently, it is difficult to install Sugar on an XO-1 
with 1GB storage and not possible for an XO-1.5 with 2GB storage.

ASLO needs to be supported. We certainly do not need to make activity 
bundles dependent on a distribution - setup.py is fine.
