@jcredding I don't love having to have a script added to each one of our repos like this.  Its overhead and I have to have the versions in the script installed or update as we change versions.

What do you think about: redding/rb#39 as a replacement for this?  This way you just do `rb each -- bundle exec assert` and you run assert against all installed rubies.  That cmd works with aliases or you can alias it as well.
