I've never used Monticello Configurations before, and would like some  
guidance before I screw up the trunk (there's your motivation to  
answer quickly, hah!  :-).  Here are my questions:

I don't feel like adding each package individually, since this seems  
error-prone and is definitely tedious.  Is it safe to add packages  
using match '*'?  This seems a bit dangerous, because I might  
inadvertently add a package that doesn't belong (eg: if I'm also  
working on a package that isn't in trunk/).  Is there a way to start  
from a previous configuration?  In other words, can I populate a new  
configuration using the latest versions of all packages in a previous  
configuration?  If not, how do others go about this?

Can you specify multiple version of the same package in a single  
configuration?  For example, if I want to load Compiler-jcg.85 before  
Compiler-jcg.86, can I add them in that order to a Configuration, or  
do I need to create two Configurations?

Thanks,
Josh
