if __FILE__ == $0 problem with main.

Question

Hi, Im currently working on a project for my first course in Ruby. A part of the assignment is to have a main class as the one below. I have it in a separate file and the other modules and classes are in separate files. Now Im getting an uninitialized constant Main::Camping (NameError) which I dont get. Any clues to why?! Thanks

Regards

class Main  

if __FILE__ == $0   
    $camping = Camping.new(32, 12)  #creates a new camping     

    include Menus
    $current_menu = main_menu

    # loops through the menu
    while (true)
        puts $current_menu
        choice = Menus.get_input
        $current_menu.make_menu_choice(choice)
    end
end   

end

Where is the file that defines Camping or 'Menu'? You will need to 'require' those files:

require 'camping'
require 'menus' # etc

class Main
#..
