The object-oriented programming language is available as a port on
FreeBSD. Ruby combines syntax inspired by Perl with Smalltalk-like
features and is influenced by Eiffel and Lisp as well. With Ruby you can
make use of multiple programming paradigms, including functional,
object oriented, imperative and reflective. The automatic memory
management and a dynamic type system are one of the main key factors to
use Ruby.
