title: Multiline comments in Kivy
body: <p>I would like to know how to use multiline comments in a kivy (.kv) file.
  I tried the following codes and neither of them worked but the one line comment '#' works well.</p>
  
  <pre><code>"""
  I am
  a multiline
  comment.
  """
  
  '''
  Me
  too...
  '''
  </code></pre>
