This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.

== 

        # Method.==

(from ruby core)
---
    meth.eql?(other_meth)  -> true or false
    meth == other_meth  -> true or false

---

Two method objects are equal if they are bound to the same object and
refer to the same method definition and the classes defining the methods
are the same class or module.

This is MURDOC! A Ruby documentation browser inspired by Smalltalk-80. It allows you to learn about Ruby by browsing through its class hierarchies, and see any of its methods.
