Uninstalling Xcode 4.1 from Lion

From the PDF in the Xcode Folder:

Uninstalling Xcode Developer Tools

To uninstall Xcode developer tools on the boot volume along with the <Xcode> directory, from a Terminal window type:

$ sudo <Xcode>/Library/uninstall-devtools --mode=all

Finally, to just uninstall the <Xcode> directory you can simply drag it to the trash
