Remove all Launchpad Apps on Lion

Script to remove all launchpad apps

sqlite3 ~/Library/Application\ Support/Dock/*.db 'DELETE from apps;'
sqlite3 ~/Library/Application\ Support/Dock/*.db 'DELETE from groups WHERE title<>""'
sqlite3 ~/Library/Application\ Support/Dock/*.db 'DELETE from items WHERE rowid>2;'
killall Dock

Then you can bring in new ones by dragging them onto the Launchpad icon. From here: http://www.tuaw.com/2011/07/25/lion-deleting-apps-in-launchpad-and-starting-clean/
