+==================================
+Publishing views from ZIP archives
+==================================
+
+Python packages can be imported from ZIP files.  Zope supports using
+such packages as extension providers: ZCML can be loaded from them and
+they can provide views based on templates or other data contained
+inside the archive.
+
+This document demonstrates this facility.  The Python harness for this
+test (test_zipped.py) has added a ZIP file containing a sample package
+to sys.path, and loaded ZCML that loads a view from that package.
+
+Since the ZCML has already been loaded, we can check that our view is
+available::
+
+  >>> print http("""
+  ... GET /@@sometext.html HTTP/1.1
+  ... """)
+  HTTP/1.1 200 ...
+  <div>(This is some text.)</div>
+
+This is the text provided by the view class in in the `sampleview`
+package's __init__.py, wrapped in the <div> element from the myview.pt
+template also contained in that package.
