Introduction

You include can call load and require themselves.

For example, assume a.rb contains the following: 

require 'b'

and b.rb contains the following: 

require 'c'

and c.rb contains the following: 

def example 
  puts "Hello!" 
end

and d.rb contains the following: 

require 'a' 
example

When d.rb is then run, 

Hello!

d.rb includes a.rb with require, a.rb includes b.rb, and b.rb includes c.rb, meaning the example method is available to d.rb.
