I did a quick, pseudo-system audit this morning and found an unexpected directory hogging up ~10GB of space on my drive. I assume that it's a remnant from a reasonably recent upgrade to XCode 4, but that's more of a guess than anything else.
I'm not an Objective-C/Cocoa developer. XCode is really installed just to support Homebrew. Off the top of my head, I can't think of anything else that I do with it.
Are these older 3.2.x directories safe to delete if I can reinstall Xcode 4 or will doing so make kittens cry?
