Thanks for this. I did some extra work on it (via someone else's fork) so it can run across multiple directories. I've too many projects lurking around to cd into all of them! I added some pretty colours too :)
I think we should ask the gem owner to verify that everything is ok unless there's a new version.
I updated the script to report if there is a new safe version available.
