卸载Xcode 4.5 Developer Preview

I installed Xcode 4.5 DP1 when it was released to developers. However, now that Xcode 4.5 was released in the Mac App Store, I no longer need the DP1. How can I completely remove it (and the new versions of the dev tools that it installed, if any) without affecting my regular Xcode installation? Thanks in advance!I installed Xcode 4.5 DP1 when it was released
