Anyone who's been following the CVS repository knows that the current  
version is pretty different from MASON 11.  So it's time to release  
12.  But before we do so, we're looking for interesting items to  
add.  The CVS server now has a contrib directory and we'll gladly  
place items there that are done by people outside of the main MASON  
team (like Jung bindings) or which we've done but have tended to keep  
as separate modules (like our social nets module and parameter  
tutorial).  If you have anything you'd like to make public, let me know.
