# Show Rails version number and quit Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify. You can specify extra command-line arguments to be used every time 'rails new' runs in the .railsrc configuration file in your home directory. Note that the arguments specified in the .railsrc file don't affect the defaults values shown above in this help message. 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
