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

to_s

        # Gem::Requirement.to_s

(from ruby core)
### Implementation from Object
---
    obj.to_s    -> string

Returns a string representing *obj*. The default #to_s prints the
object's class and an encoding of the object id. As a special case, the
top-level object that is the initial execution context of Ruby programs
returns ``main''.
