How can I load the RefactoringBrowser into Squeak 3.9?

Hi,

I have worked with Visual Works smalltalk before, but
I am new to
squeak. I want to install the Refactoring Browser on
my newly
installed Squeak 3.9 (on Ubuntu Feisty if that
matters) and can't
figure out how.
The World Menu -> Open -> Squeak Package Loader, where
there are
several refactoring browsers but nothing for 3.9.


There is a "Refactoring Engine" . Its explanatory text
says

"This is the Refactoring Engine. (It's the Refactoring
Browser without
the Browser and AST)." huh ? what does "Refactoring
Browser without
the Browser" mean?


One more question, I'll probably explore the squeak
library by adding
unit tests for various classes. Is there a process by
which I can
submit these tests as a patch? Sorry if this question
("How do I
submit a patch" has been addressed before, but I
couldn't find it
anywhere.

Thanks in advance,
Ravi
