  Description:
      The 'rails new' command creates a new Rails application with a default
      directory structure and configuration at the path you specify.
  
  Example:
      rails new ~/Code/Ruby/weblog
  
      This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
      See the README in the newly created application to get going.
