+===============================================================
+loops - Linked Objects for Organization and Processing Services
+===============================================================
+
+Integration of external sources.
+
+  ($Id$)
+
+
+Setting up a loops Site and Utilities
+=====================================
+
+Let's do some basic set up
+
+  >>> from zope import component, interface
+  >>> from zope.traversing.api import getName
+  >>> from zope.app.testing.setup import placefulSetUp, placefulTearDown
+  >>> site = placefulSetUp(True)
+
+and build a simple loops site with a concept manager and some concepts
+(with a relation registry, a catalog, and all the type machinery - what
+in real life is done via standard ZCML setup or via local utility
+configuration):
+
+  >>> from loops.integrator.testsetup import TestSite
+  >>> t = TestSite(site)
+  >>> concepts, resources, views = t.setup()
+
+  >>> len(concepts) + len(resources)
+  18
+
+Fin de partie
+=============
+
+  >>> placefulTearDown()
