Tabulous provides an easy way to add tabs to your Rails application.
Future support for tabulous is uncertain, so you may not want to start a new project with it. See FUTURE for details.
Tabulous officially supports Rails 5.0, 4.2, 4.1, 4.0 and MRI Ruby 2.3, 2.2, 2.1 and 2.0.
Tabulous should also work with Rails 3.2, 3.1, 3.0 and MRI Ruby 1.9 but automated tests to verify this have been removed.
Tabulous definitely does not work with Ruby 1.8.
