I just changed the Squeak Wiki http://wiki.squeak.org/squeak/227 entry about the RefactoringBrowser to what you see below. If what I've said is wrong, please say how. Also, the username/password for changing the Squeak Wiki is squeak/viewpoints. Anybody can contribute or update.

The RefactoringBrowser is now a series of menues in the OmniBrowser. You get the OmniBrowser in your system by executing this code in a Workspace.
"Omnibrowser" (Installer wiresong project: 'ob') install: 'OmniBrowser'; install: 'OB-Morphic'; install: 'OB-Standard'; install: 'OB-Shout'; install: 'OB-SUnitIntegration'.
"Refactoring engine and OB integration" (Installer ss project: 'rb') install: 'AST'; install: 'Refactoring-Core'; install: 'Refactoring-Spelling'; project: 'Regex'; install: 'VB-Regex'.
(Installer wiresong project: 'ob') install: 'OB-Refactory'; install: 'OB-Regex'.
Once you've done that, when you reach for a browser, it will ask you which of three browsers you want: Packaging, Omni, or regular. You can change from one to the other by clicking on a menu on the top rim of an open browser.
