That is
http://www.bobjectsinc.com/squeakrbalpha/download/LintUI.9.cs.gz

Decompress and file it in after the RB-files and execute "LintDialog open".
Then select items in the different panes and hit the "RUN" button. Only
select a few classes until you have a feeling for the expected execution
time or at least schedule a coffee-break ... Click on an item in the
resulting report and a RB opens.

First impression: it seems to work fine. (The RBs for "Variables not
referenced" do not show the names of the variables.)
