Why the Ruby dependency for creating cookbooks?
I don't prefer installing frameworks I'm not using as add-ons for another product - can vagrant do the extras?
Well, Vagrant provides a hook for different provisioning frameworks. I believe that Puppet and Chef and officially supported. The project uses Chef, which is written in ruby and uses ruby-based cookbooks to do its work. So it is pretty unavoidable. Also, Vagrant is written in Ruby last I checked, so if you are using Vagrant you already have a Ruby dependency.
Sorry if I've misunderstood.
As an aside, I thought it would be cool to build a service like this, so it's great that somebody did it. However the name definitely has the wrong connotation.
We are waiting for 1.2.0 Vagrant release to make use of the librarian plugin. Vagrant self-installer will solve Windows issue. It contains several tiny bugs atm unfortunately :(
