  $ ./new_rails_project --no-svk -r http://terralien.com/svn/terralien/
  myproject

Result:

  p options.svk                 # => false
  p options.project_path        # => '/Users/ntalbott/svk'
  p options.repository          # => 'http://terralien.com/svn/terralien/'
  p options.create_structure    # => true
  p options.project_name        # => 'myproject'
