I’m using Xcode for this bit because TextMate just tells me the bundle is already installed when I try opening any of its contents from Finder. This works fine for me, but please alert me if I’m being dumb about it.
Hold down the option modifier key (⌥) when you open the bundle then TextMate will open the bundle as a folder.
