I added the repository with the "+Repository" button and the Monticello registration info from the smalltalk hub site.
I loaded all the packages (!) and some were automatically changed on recompilation.
Is there a way to do this with less clicking? I selected each repository package in Monticello, clicked the latest version, then clicked the Load button.
I used the System Browser to navigate to the package and see the added methods (some exploratory clicking got me there...):
As for the CBO (couplingBetweenClasses) metric, it seems way off (at least with my comparisons with fanIn and fanOut, but I didn't verify their values either!). I will follow up here if I nail down the inconsistency.
These packages are a useful place to start. Thanks again for the help,
