# The correct way is to do this.

# Possibly with some additional stuff here,
# but note the trail.

module YayComments

  ##
  # Sometimes you need the double-hash, so you do this.
  #
  # And continue here as needed.
  #
  attr_accessor :wee

  # This is not good,
  # leaving a space.

  def foo
  end

  ## And this I really don't like either
  #  because it just looks weird.
  def moomin
  end

# Sometimes I leave a space here, but I might not.
