Running

Start the application with padrino s. Then browse to http://127.0.0.1:3000/master/hello to get the master and to http://127.0.0.1:3000/master/v1/hallo to get the mounted v1 app inside of api/api.rb

The only caveat is that you need to include the in config/apps.rb:

# Mounts the core application for this project
Padrino.mount('V1', :app_file => Padrino.root('api/v1.rb'), :app_class => 'Grappe::V1') # this one needs first
Padrino.mount('Api', :app_file => Padrino.root('api/api.rb'), :app_class => 'Grappe::Api').to('/master')
