Three changes to loadup scripts:
1) dribble files are now copied from the workdir into loadups if loadup completes successfully,
2) if the lock preventing simultaneous runs is already set when loadup starts, it now asks the user if they want to override the lock or to exit (previously it just exited),
3) there is now a --override flag that will automatically override the lock without asking the user.
Man page updated accordingly.
