-  <p>
-    This is a small example application that shows how to integrate
-    Mozilla's persona signin service into a Flask application.
-  <p>
-    The advantage of persona over your own login system is that the
-    password is managed outside of your application and you get
-    a verified mail address as primary identifier for your user.
-  <p>
-    In this example nothing is actually stored on the server, it
-    just takes over the email address from the persona verifier
-    and stores it in a session.
-  {% if g.user %}
-  <p>
-    You are now logged in as <strong>{{ g.user }}</strong>
-  {% else %}
-  <p>
-    To sign in click the sign in button above.
