== DESCRIPTION:

restarts.rb implements a new method Kernel#raise_condition which
is similar to Kernel#raise for throwing exceptions, with the added feature
of adding "restarts" next to the place where the exception is thrown so
that they can be invoked from the exception handler somewhere higher
up in the stack.

      when :ID1 then do_something_more()
      when :ID2 then do_something_even_more()
      end

  end
end
