And also, is you want to have access to @config and @database from the
outside, then as already mentioned then all instance variables (the
ones with @) are private. That means you have to use methods to set
and get the values of those variables. So you could create a methods
like this:

class Web
  def config
    @config
  end

  def config=(new_config)
    @config = new_config
  end
...
end

But, since most of the time the get and set methods are defined just
like the ones above then you can create those methods semi-
automatically by an accessor methods. So, to define an get and set
methods for @config and @database, you can do it like this:

class Web
  attr_accessor :config, :database
end

Or if you want just a get methods use "attr_reader" instead. And for a
write-only access "attr_writer".

Enjoy Ruby!
