For now, have a look at site.pp
to see whats included.
rake rebuild
This will output a box named like quantal64-dev-box-2013-01-23.box
that you can
add to vagrant with vagrant box add quantal64-dev-box-2013-01-23 /path/to/quantal64-dev-box-2013-01-23.box
.
Please note that it takes ~20/25 minutes to rebuild the VM on my laptop using a 15mb connection, so go grab a coffee while it runs ;)
I keep the latest release on a public folder at my dropbox account, feel free to use it:
vagrant box add quantal64-rails-2013-01-23 http://dl.dropbox.com/u/13510779/quantal64-dev-box-2013-01-23.box
