title: simple markup for jinja2 or html textarea
body: <p>I am writing a google app engine web app using python and jinja2.  Is there a simple lightweight textarea markup that I can use either for jinja2 or just generally for an HTML text area.  I just want line breaks to come across and italics and bold and maybe one or two other things but I don't just want to mark is safe (and not autoescape the rest of it).</p>
  
  <p>I am surprised that no one has asked a similar question and they probably have so maybe I'm just using the wrong keywords.</p>
