Thanks for that link. For future google searches, the exact link to the example is here:

@Héber, does ruby come installed with PlasticSCM? We can't install ruby on client machines, I'm not sure if that example would actually work on all the machines. Is there a generic variant or does ruby work with all Plastic installs?
We can install ruby on our server if there is a server-trigger that would work for the same purposes.
