I've created a dedicated page to MASON Sugarscape. It includes links
to the full package and to the subversion repository for the latest
bleeding edge Sugarscape source code on java.net.

I've also just released 1.1.1 which has some performance optimizations
and continued cleanup of the primary model class code.
