+<p>JobView tells Zope how to display a Job.  Because this is a rather
+straightforward view, we don't have to write any Python code: instead,
+it is coded as a page template.  This is an HTML-like file with
+embedded directives in the form of attributes that cause substitutions
+to happen.  More about page templates later.
+<p>The view is attached to the Job class by means of a single
+statement in the configuration file:
+&lt;browser:view name="index.html"

+              template="JobView.pt"
+              permission="Zope.Public" 
+              />
+<p>This tells Zope that there is a view named index.html which applies
+to instances of the IJob interface, implemented by the page template
+JobView.pt, and requiring the permission Zope.Public (a fancy way to
+say that anyone can view the job; more about permissions later).
