This is an edited version of jajb's script found in this thread.

Note!

After a fresh install of a ROM, first do a system boot before installing this script. This removes apps that are called on first startup (for configuring some system settings), so flashing the script before doing so will result in a bootloop.

Also, to avoid a bootloop caused by the removal of Velvet.apk, go to Settings > Apps > Default apps > Assist & voice input and make sure it's set to none. Or edit the script to keep Velvet.
