    #to_request_set(development = :none)  
  



  

    

Converts this AvailableSet into a RequestSet that can be used to install gems.



If development is :none then no development dependencies are installed. Other options are :shallow for only direct development dependencies of the gems in this set or :all for all development dependencies.
