Binary package “rails” in ubuntu trusty
MVC ruby based framework geared for web application development
Rails is a full-stack, open-source web framework in Ruby for writing
real-world applications.
.
Being a full-stack framework means that all layers are built to work
seamlessly together. That way you don't repeat yourself and you can
use a single language from top to bottom. Everything from templates to
control flow to business logic is written in Ruby.
.
This is (almost) empty dependency package which provide the rails
command which runs the defaults version of the rails. If you need
a specific version of rails, you need to depend on ruby-rails-VERSION
package.
