title: Reading a TextGrid file into NLTK
body: <p>I'm trying to read in a TextGrid file into NLTK, but I'm having some trouble.
  I understand that there is a parser for Textgrid ( as seen here: <a href="http://nltk.googlecode.com/svn/trunk/nltk_contrib/nltk_contrib/textgrid.py" rel="nofollow">http://nltk.googlecode.com/svn/trunk/nltk_contrib/nltk_contrib/textgrid.py</a>).</p>
  
  <p>Unfortunately, I'm new to NLTK, and I have no idea how to use the parser.</p>
  
  <p>Any help would be very appreciated.</p>
