+``paste.evalexception`` lets you interactively debug exceptions in
+your WSGI app.  ``z3c.evalexception`` is a small wrapper around that
+so that it works with the stock Zope 3 application server.
+
+Here's a simple PasteDeploy configuration file that sets up the Zope 3
+application server on top of the WSGIUtils HTTP server with the
+``z3c.evalexception`` middleware::
+
+  [filter-app:main]
+  use = egg:z3c.evalexception
+  next = zope
+
+  [app:zope]
+  use = egg:zope.paste
+  site_definition = parts/app/site.zcml
+  file_storage = parts/data/Data.fs
+
+  [server:main]
+  use = egg:PasteScript#wsgiutils
+  host = 127.0.0.1
