title: Organising Rails source files
body: <p>If i want to move <strong>/lib/foo_bar.rb</strong> to <strong>/lib/tidy/foo_bar.rb</strong> or even <strong>/lib/tidy/somestuff/foo_bar.rb</strong> </p>
  
  <p>must i declare <strong>FooBar</strong> to be <strong>module Tidy</strong> or <strong>module Tidy::Somestuff</strong></p>
  
  <p><em>in other words</em> must the modules match the directory structure?</p>
