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.
