Adhearsion is for Ruby on Rails?
This is one of the biggest misconceptions about Adhearsion. It should be strongly stressed that Adhearsion is a Ruby framework, not a Ruby on Rails plugin or the like. Ruby on Rails, a web development framework, is probably the most popular Ruby software, but it has little to do with the Ruby language per se besides simply using it. The Ruby language is a general purpose programming language with which both Ruby on Rails and Adhearsion are written. Adhearsion does help facilitate integration with Rails applications and it shares a few libraries with Rails, such as ActiveSupport and ActiveRecord. In Rails-integration mode, Adhearsion still exists as a completely separate process.
