[Pharo-project] how do I rename a package?

I discovered to my astonishment that there is no contextual menu item in either the MC browser or the OB system browser to rename a package! I know how to move all classes and methods from one package to another programmatically, but shouldn't there be a way to rename a package? http://scg.unibe.ch/wiki/faq/pharofaq/howToMoveCodeBetweenPackages Couldn't figure out how to do this. - on
