Ruby module methods accessibility

I have the following module:

module Foo
  def f1 x
   puts "f1(#{x})"
  end
  def Foo.f2 x
   puts "f2(#{x})"
  end
end

When it is included into a class:

class Bar
    include Foo

    Foo.f2 "bar"   # This works
    f1 "bar"       # Missing method

    def b x
        f1 x       # This works too
    end
end

Why is the behavior of f1 different in the two cases?

How is the scope of module metods defined?

Can f1 be written in such a way, that it would work as in the case f1 "bar"? Like for example the task in Rakefile?

If you want to add class methods to Bar you'd want to use included; see Yehuda's post on the subject. It depends (somewhat) on what you're actually trying to do.
