rails - 2:5.2.2.1+dfsg-1+deb10u3 main

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 a metapackage.
