[Pharo-users] How to tell Versionner to load certain additional packages?

I created a ConfigurationOfArtie ( http://smalltalkhub.com/#!/~SergiReyner/Artie) that loads Bootstrap, Magritte3, Pillar and ApplicationSecurity. I´d like it to load some other packages like Magritte-Seaside or Bootstrap-Magritte. How to tell it to do so with Versionner? Cheers, Sergi
