+
+This package provides a page template engine implementation based on
+Chameleon. It plugs into the `zope.pagetemplate
+<http://pypi.python.org/pypi/zope.pagetemplate>`_ package and has an
+explicit dependency on this package.
+
+You can use the package to replace Zope's reference template engine
+with Chameleon in an application based on the Zope Toolkit.
+
+Configuration
+-------------
+
+The package is configured via ZCML.
