You need not put each class in a file. Normally you put each chunk of
logically connected code into on file, that may well be more than one
class, or in special cases also only half a class. Then you require
the files into the main file and start using the classes.

E.g.

main.rb:
---
require 'ui_1.rb'
require 'ui_2.rb'

class Datastructure
  ...
end

class Program
  def initialize
    @ui1 = UI1.new(42)
    @ui2 = UI2.new("Hello world")
  end

  ...
end

Program.new
---

ui_1.rb:
---
class UI1
  ....
end
---

ui_2.rb:
---
class UI2
  ....
end
---

etc.

Brian
